Chapter 180

"Now I feel that I am a little overconfident! I am thinking about whether I should write a letter home and ask a powerful fellow apprentice to come over!"

Xu asked: "..."

"No, no, no! It may be a little chaotic on the road, but now we are in the capital, everything will be fine!" Xu Wen waved his hand to stop them, "This is the so-called imperial city, the public security is good!"

It's not that she doesn't know what's right for her, it's just that this is really going too far.

And Sister Mulan may be more aggressive due to her personality. She said she would call her fellow apprentices at home, and if Xu Wen didn't stop, then in two days he would definitely see the fellow apprentices appearing out of nowhere.

Mulan's wife thought about it and agreed. Since we have reached the old city, there should be no problem.

After a long and tiring journey, Xu Wen had no time to rest and was in no hurry to go to school. He took his wife Mulan to the guesthouse under the jurisdiction of Lu Yuanzheng's unit and booked a better room.

There are many inconveniences and potential safety risks for two lesbians to go out together. So when it comes to booking a room, Xu Wen never skimps and always tries to pick a better and more expensive hotel.

If there is no suitable hotel or there is a more suitable guesthouse, stay in a guesthouse.

There are differences between guest houses, inns and hotels.

A guesthouse generally refers to a place operated by a unit to provide rest for employees or their families. It usually only provides accommodation services, and meals are also served in the unit's small canteen.

For example, the guesthouse they stayed in Haicheng belonged to Li Daoming's unit.

The place where Xu Wen lived in the compound was the guesthouse of Lu Yuanzheng's unit.

Lu Yuanzheng and his unit were pushed up level by level until finally they got the name starting with the word "国".

Like their guesthouse in Beijing, the scale and treatment are very good.

As for guest houses and hotels, they are both commercial in nature and sell services. The difference between them lies in the scale, consumption level, etc.

In addition, a simple hotel does not provide meals, but a hotel does.

Therefore, in terms of investment amount and service, the hotel is superior.

Xu Wen said that if he settled in Pengcheng, he would like to stay in a hotel, and if he went to Haicheng, he would like to stay in a guesthouse.

In the capital, the best place is of course the guesthouse.

The reason is simple: in the 1980s, under the imperial city, good guesthouses were more comfortable than ordinary hotels.

Both of them were military dependents. With letters of introduction from their expedition unit, they stayed in the guesthouse under the jurisdiction of their unit.

In this way, the safety and food of the two lesbians are guaranteed.

On the first day in the capital, Xu Wen and his wife Mulan both took a good bath to wash off the dust and slept soundly.

When I woke up again, it was already bright daylight.

The next day.

Early in the morning, Sister Mulan saw that Xu Wen looked a little depressed and asked in confusion, "Sister-in-law, what's wrong with you? Are you feeling unwell?"

Xu Wen shook his head, seeming to want to say something but stopping himself.

We are all women, so some things don’t need to be said clearly, Sister Mulan understood immediately, “Oh, do you miss your home, Luying?”

Xu Wen's face suddenly turned red.

This is what it's like dealing with a sister-in-law who has a straightforward personality; you never know what she might say that will catch you off guard.

Although the facts were almost the same and she and Lu Yuanzheng were an old couple, Xu Wen still felt a little embarrassed.

Xu Wen and Lu Yuanzheng are rarely together nowadays.

The first week after every breakup is always extremely uncomfortable, with no relief at all.

This condition usually gets better after a week.

It doesn't mean that you won't miss the other person after a week, but you will be relatively accustomed to the other person not being around. Although you will miss the other person in your heart, you won't be worrying about him/her too much.

Sister Mulan didn't notice Xu Wen's embarrassment. She frowned and looked towards the south, sighing deeply: "I miss my old Wang too."

"Sorry!" Xu Wen said.

Because of her, Sister Mulan separated from Squad Leader Wang Bin.

Sister Mulan waved her hands, "Sister-in-law, don't be so polite all the time. I'm not used to it! Besides, I've always been looking forward to going out with you to see the world. It's boring to stay on the island all the time! Not only is it boring, but I don't like our Lao Wang either.

There is an old saying in our area: "Far away, the fragrance is good, near, the stench is bad." It means that people will be more intimate if they keep a certain distance from each other. But if they are together every day, it is easy to get tired of each other and dislike each other!

My son, Wang, and I have been getting to the point where we just don't like each other. You don't know how annoying it is when I see him throwing his socks around or not picking up the trash on the table when I'm at home!

Every day I threatened Lao Wang that I wanted to go back to my hometown.

It’s only after meeting you that I realized that being annoyed with him and missing him are not contradictory. I don’t want to go back to my hometown. I was really annoyed when I saw him, and I really missed him after I left.”

Sister Mulan spoke very quickly, her words snapping like beans pouring out of a bamboo tube.

"But, no matter how much I miss him, I'm still willing to go out with you! Although it's a bit annoying with so many people, it's lively. And, I'll tell you a secret. I've dreamed of coming to the capital since I was a child!"

Jiao Mulan moved closer to Xu Wen's ear and lowered her voice.

At this moment Xu Wen thought she was going to tell him some shocking secret, so he leaned sideways and listened attentively.

"I watched a movie when I was a kid! The scene of the flag-raising in front of the □□ was so cool! So I have liked soldiers since I was a kid. When I grew up, I also wanted to be a soldier, but I was not tall enough! Later, my only wish became to marry a soldier. Although I got married, I still didn't get to see the national flag raising in front of the □□.

This time I finally got what I wanted!"

Xu asked: "..."

So, your big secret is that you want to watch the flag-raising ceremony? Or that you want to marry a soldier?

It doesn’t matter which one, they can all be achieved or have already been achieved.

Xu Wen nodded, not knowing whether to laugh or cry. "We got up late today. Let's go watch the national flag raising tomorrow morning. We won't have dinner at the guesthouse this morning. I'll take you to try some special snacks in Beijing first."

"Great!" Sister Mulan became more energetic when talking about food. She touched her stomach and said, "The food on the train is too bad. It's a good opportunity to visit my five dirty temples."

After having dinner with Sister Mulan, the two went to Xu Wen’s school first.

After entering the school, Sister Mulan stopped making so much noise and just stayed quietly beside Xu Wen, causing Xu Wen to keep looking at her sideways.

Sister Mulan sighed, "Don't look at me! I'm normal and I'm fine. The main thing is, you know? Semi-illiterate people like us have an instinctive respect for schools. What's more, your school is inlaid with gold and silver! I will try my best to act cultured and not embarrass you!"

Xu Wen laughed and shook his head, "Sister-in-law, I finally understand why Squad Leader Wang likes you so much! You are so cute! But you don't have to wrong yourself, just be yourself, it's okay."

"Really? Won't it embarrass you?" Sister Mulan wondered.

"How could you possibly embarrass me? Compared to us students who only know how to study, you are also very good at martial arts! Many martial arts have been slowly lost!"

"That's true. Practicing martial arts is hard and tiring! There are fewer and fewer people who can persevere, and even fewer who can become famous."

Thinking of this, Sister Mulan felt that she was not so inferior anymore. She straightened her back a little and held her head high.

Xu Wen first went to say hello to his counselor and expressed his request to meet the principal.

Xu Wen is a legendary figure in Peking University. She does not come to study, but her grades are much better than those of the students on campus.

Even the counselor only saw her once or twice a year. Seeing that she came to the school on her own initiative, he guessed that something important had happened. After thinking about it, he said he would go and ask her first.

It is impossible for the president of such a large university to wait for Xu Wen to give advice at any time.

Xu Wen still has the self-awareness that he needs to queue up for reservation.

After making an appointment with the counselor to come back the next day, Xu Wen left school.

Then Xu Wen took Mulan's wife to find an old friend.

Mulan's sister-in-law had also met this person, Tan Changlin.

Tan Changlin's unit has very high confidentiality requirements, so if you want to meet him, you have to go through a series of cumbersome procedures and wait for a long time before you can see him.

When Tan Changlin saw Xu Wen, he was obviously frightened, "Why are you here?"

"Come to see an old friend! What? Not welcome?"

"No, no, no, you're so welcome! Wait, I'll go back and take a day off so I can take you guys out for dinner."

Tan Changlin took leave quite quickly and was released not long after.

It's almost time for dinner now.

Beijing has a lot of delicious food, but the most famous ones are roast duck and noodles.

Three people ordered four dishes and a bowl of fried noodles each.

Sister Mulan was concentrating on eating. She had never been to the capital, and had never eaten these before, so it was very new to her and she ate with gusto.

Xu Wen comes here every year and has eaten there a lot in his previous life, so he is not too interested in the food. He mainly comes to chat with Tan Changlin.

"Ouch! I almost forgot that you are still a college student!" Tan Changlin slapped his forehead, "But..."

He looked at Xu suspiciously and asked, "With your ability, there's no need to come all the way from Rainbow Island just to write a paper, right?"

He didn't think it would be difficult for Xu Wen to write a thesis.

"I also need a tutor to guide me!" Xu Wen lied with his eyes open.

Tan Changlin sneered. Although he didn't say anything, this smile expressed his attitude vividly.

"Okay! Then I'll tell you the truth. I'm here to do business." Xu Wen took out a few individually packaged diapers from the bag he was carrying and placed them on the table.

"What is this?" Tan Changlin picked up a piece curiously and looked at it over and over again.

The words on it were large, and Tan Changlin recognized them. "Is the urine wet?"

Although the specific meaning of "urine does not wet" is unclear, these three words are enough to get the point across.

"Yes, it is mainly used on babies, and there are detailed instructions for use at the back." Xu Wen was afraid that many people would not understand it because they were illiterate, so he asked his sister-in-law, who was good at drawing, to draw a very detailed picture tutorial. A very cartoony and cute sketch.

Tan Changlin: “…”

He can understand both pictures and words.

The problem is...

"I'm a single, unmarried young man, and you're giving me urine?" Isn't that a bit inappropriate?

"Who gave it to you? This thing is very expensive! I want you to help give it to your colleagues who are married and have kids. Let them try it out and it would be best if they can give me some feedback. I tell you, this is a magic tool for taking care of kids..."

Xu Wen talked for a long time about the benefits of not getting your urine wet.

Sister Mulan was so excited after hearing this that she wished she could go back and have a child to play with.

However, Tan Changlin, who had a background in science and engineering, remained rational and listened with little interest.

After Xu Wen finished speaking, he only said one sentence: "Why bother to say so much?!"

Xu asked: "..."

She rolled her eyes in annoyance. "I'm not saying this just for you! I hope you can convey this to my future clients!"

Tan Changlin: “…”

So he is just a mouthpiece?

With Tan Changlin's profession, he will definitely be a high-income earner in the future, and his colleagues will have enough spending power to try new things.

Although diapers are disposable items, they don't cost much to buy one each.

But, it can’t withstand long usage time!

Children from zero to three years old basically use it.

Therefore, the cumulative orders brought by a buyer are not a small number.

Xu Wen blinked, "Of course not! Am I the kind of person who would take advantage of my friends?"

Tan Changlin snorted.

"I don't know if you are that kind of person. But since we met, you have been getting more and more comfortable with calling me names. And even after calling me names, I haven't seen you do anything like friends should do."

"Why not?" Xu Wen argued unconvincedly, "Didn't I come here to treat you to a meal today?"

Tan Changlin: “…”

After a long while, he only managed to say: "Then I have to eat more today."

After all, as a man, it is quite novel to be invited to dinner by friends who come from far away at your doorstep.

"Young people nowadays are becoming less and less lovable." Xu Wen shook his head and said his real purpose, "Okay! Selling urine is indeed a side job. I have more important things to do."

"What?"

"I want to make a satellite phone!"

Tan Changlin was stunned for a moment, then his eyes widened like bells. After looking at Xu Wen for three seconds, he rolled his eyes until only the whites of his eyes were left looking at Xu Wen, while sneering, "Why don't you go to heaven? Do you know what you are talking about?"

Satellite phone?

Let’s not talk about satellites for now.

Just the phone.

Who can use the telephone nowadays?

How many of you can afford a private phone?

Not to mention satellites?!

Satellite!

That's something in space.

Can ordinary people play it?

Xu Wen, a quiet girl, has such big ambitions!

This tone is even more arrogant!

It's so big that it can't even be described by bragging.

So even though Tan Changlin laughed at her, she didn't take it to heart at all.

"I'm serious." Xu Wen said seriously.

"Do you know what a satellite phone is?"

Xu Wen nodded, "Of course, it is a phone that transmits information based on a satellite communication system."

Tan Changlin suddenly felt a toothache. "How can you say such ridiculous things in a tone like 'Do you want to eat fried dough sticks or steamed buns today?'"

This time it was Xu Wen's turn to roll his eyes, "This is not some fantasy."

Obviously, satellite phones will be a common thing in a few decades.

For most ordinary people, using wireless communications and satellite communications are just like making phone calls. There is not much difference, and no one will be surprised.

"Fuck!" Tan Changlin stood up and looked Xu Wen up and down, still not daring to believe it, "Are you serious?"

Sister Mulan, who had been eating hard, was like a lioness whose fur suddenly stood up the moment Tan Changlin stood up. She stretched one arm across Xu Wen, held the chopsticks in one hand, and looked at Tan Changlin vigilantly.

It seemed as if he was going to stick the chopsticks into Tan Changlin's eyes in the next second.

Xu asked: "..."

Tan Changlin: “…”

Xu Wen hurriedly pulled Sister Mulan, "Sister-in-law, don't get excited! He is really my friend. It's just that maybe what I said scared him a little, so he lost control! He didn't mean to hurt me."

Tan Changlin lost control even more, his voice was a little hoarse from being too shocked, "Xu Wen, you actually go out with a bodyguard now?!"

"You are the bodyguard!" Xu Wen rolled his eyes in annoyance, "This is also a military wife from Rainbow Island. She was worried that I would be unsafe on the road alone, so she came here with me."

Tan Changlin took a deep breath, and then another deep breath...

Sister Mulan asked Xu Wen doubtfully: "He looks thin and weak and unhealthy. Is he going to have a seizure?" He is shaking like this? !

Tan Changlin: “…”

A breath of air stuck in my chest, making me even more depressed.

Xu Wen chuckled and shook his head, giving Tan Changlin time to react.

Sister Mulan, however, still looked at Tan Changlin with caution, "It was just a phone call, why did he get so excited?"

Although telephones are rare, they shouldn't be that exaggerated, right?

She came from a small martial arts school and had seen a telephone before, not only had she seen it but had also used it.

Before she married Wang Bin and before Wang Bin was transferred to Rainbow Island, she would call Wang Bin from time to time using a public phone.

It's only a few cents a minute, which is not expensive.

From what Xu Wen said, it seems that Tan Changlin is not someone who can't afford to pay a few cents. Why would he be so excited?

It's not that Tan Changlin didn't notice Sister Mulan's contempt, but he was too frightened and really didn't want to bother with her.

However, Sister Mulan is a simple person, and her thoughts are written on her face, so Tan Changlin can't pretend not to see it.

He let out a long breath, but couldn't help but speak to Sister Mulan, "You know she..." He pointed at Xu Wen, "What is she going to do?"

Sister Mulan's eyes suddenly became very gentle when she looked at Tan Changlin, as if she was caring for a mentally retarded person. Her tone was sad: "I know! Didn't she say it? She wants to be a telephone."

Although it is not clear why Xu Wen wanted to make a telephone, telephones are not something rare and there is no need to be so surprised.

After all, Xu Wen can also print directly to the factory!

Tan Changlin felt like he was about to choke on his breath, so he took a sip of tea to hold it down, and squeezed out some words from between his teeth: "She doesn't want to make a phone! She wants to make a satellite phone!"

"Isn't that still a phone call?" Sister Mulan blinked, very confused. It's just two more words than a normal phone call.

Tan Changlin: “…”

He didn't want to talk anymore.

Xu Wen smiled and explained for him: "Satellite phones are different from ordinary phones... For example, what I want is that when you make a call here, squad leader Wang Bin can also answer the call."

Sister Mulan said "oh".

Xu Wen thought to himself, he is indeed a martial artist, look at how strong his mental quality is.

Tan Changlin also looked at Sister Mulan suspiciously, wondering if she didn't understand.

Three seconds later.

"Oh my god!" Sister Mulan stood up and took Xu Wen's hand. Her tone was even more excited than Tan Changlin's just now. "Sister-in-law, is this true? If we make a call here, can we get the call on the island? Is this true or not?"

Tan Changlin: “…”

Xu asked: "..."

This reflex arc is long enough.

Tan Changlin felt more balanced mentally, and suddenly felt that Xu Wenyu's surprising behavior was not so difficult to accept. He calmly picked up the teacup and took a sip of the already cold tea.

Sister Mulan was still excited, "Ask sister-in-law, if this thing can be done! Then you are the one among us women!"

She raised her thumb and flexed it.

"Sister-in-law, do you know why I left the martial arts school and came to our island? It was because my husband, Wang, said that when he moved to the island, he might not be able to call me once a year. Not only could I not call, but the place was so remote that I didn't even know if the letter could be delivered! Oh my! I was so scared that I came all the way to Rainbow Island.

Although Rainbow Island is much better than I imagined, it is indeed too remote. There is still no phone on our island..."

Tan Changlin couldn't bear to listen any more and interrupted her: "You know about satellite phones... Anyway, is it possible that such a powerful thing was developed just for you to make phone calls and say sweet nothings to your man?"

Before Sister Mulan could speak, Xu Wen nodded and said, "Yes! I want to make a satellite phone just to call my man!"

Tan Changlin: “…”

No more chatting today!

After a while, Tan Changlin smiled.

"Comrade Xu Wen, you are the most talented female comrade I have ever met in my life, but you are also the most unambitious person I have ever met!" Tan Changlin sorted out his words and found that this was not quite correct.

But that's basically what it means.

"When I first met you, I looked down on you! I thought you were just relying on Lu Yuanzheng's relationship to show off your power and bully others on the island. I thought others were nice to you just to curry favor with Lu Yuanzheng.

Later I found out that you conquered the people of Rainbow Island with your own abilities.

Many of your "inventions" or "research" on Rainbow Island are world-class.

Whether it is "electric cars", "wind power generation" or "3D printing", they are all your work. At least the real core is proposed by you.

Even though…” Tan Changlin raised the urine in his hand, “This thing, at present, even if it is not unique in the world, it must be a rare thing, right?”

Although it was a question, Tan Changlin obviously did not need an answer.

"But you have no name in the world right now. Your name in China is mostly related to your college entrance exams. It doesn't matter if it's your past grades or the grades of your students. Do you know why?"

Of course Xu Wen knew it, but she didn't say anything and just listened quietly.

The more Mulan listened, the more she felt that it made sense. Xu Wen knew everything, and many things on the island were indeed her masterpieces. Following Tan Changlin's words, she asked him, "Why?"

Tan Changlin rolled his eyes and threw the individually packaged diapers back onto the table. "Because of the purpose of her doing this!"

"Ah?" Sister Mulan was at a loss.

Tan Changlin has lost count of how many times he has sighed. "She is developing wind power generation because she wants to use an electric fan. She is developing seawater desalination because she wants to take a shower. She is developing 3D printing because the Kaya has taken up too much of her husband's time, making her feel constrained on the island. She is developing urine-proofing to make it easier to take care of the children, and she is developing a satellite phone..."

He glanced at Xu Wen and let out the anger that he had been holding back for a whole meal. "Just because she doesn't want to be out of touch with her man for a long time. If I'm not mistaken, you're out at sea for a long journey and you feel it's inconvenient not being able to contact him, so you want to get a satellite phone so you can find him on the ship, right?!"

Sister Mulan: "..."

She had never thought about it so much before. She arrived on the island relatively late and didn't quite understand the reason. She subconsciously looked at Xu Wen.

Xu Wenchao raised his thumb to Tan Changlin, "You are so smart! You can guess this! Yes! I just want to contact him when Lu Yuanzheng goes out to sea, what's wrong? Not only that, I also hope that Rainbow Island can contact the outside world.

You also know that although we have temporarily solved the electricity problem on our island, we cannot solve the communication problem for the time being. Our island is too remote and too far away, and even cables cannot reach us. So we cannot watch TV or make phone calls for the time being.

There are only two solutions. First, lay the optical cable from the land, and for safety reasons, try to go under the sea. Then you can imagine how much manpower, material resources and financial resources such a project would cost. At least for the time being, this is a project that is simply impossible to achieve.

The second is to make a satellite phone. I checked and found that there are already commercial satellites launched into space. We can pay a certain fee. So the idea I proposed is not completely unfeasible. "

It is definitely achievable, but because many things are too advanced, we don’t know whether they can be made at the moment.

After all, mobile phones haven’t even come into the world yet!

This is still the era of wired telephones. It may be impossible for a single person to enter the era of wireless telephones.

After all, Magic Mirror is just a search engine. How can it possibly find out the key technologies?

However, with the help of the magic mirror, Xu Wen carefully studied the differences between wired communication, wireless communication, and satellite communication.

Especially wireless communications, in the future, most of the mobile phones people use will be based on wireless communications.

Xu Wen even studied the development process from 1G network to 5G network, and finally figured out why mobile phones are so huge.

The principle of mobile phones is mainly to achieve long-distance communication through radio waves. The disadvantage is that sometimes the signal is poor and the sound is distorted. If you are in deep mountains and forests, there will be basically no signal.

Every time a person speaks, every sound produced will produce an irregular wavy line, which is a sound wave.

The sound waves are sealed and transmitted through the antenna on the mobile phone. This is the original 1G network.

Even so, it took several years to come.

2G network is the most popular. According to statistics, more than 4 billion of the 5 billion people in the world have used it.

The difference between 2G network and 1G network is that 2G network digitizes radio waves and enters the digital communication era.

For example, as we all know, in the computer world, there are only two symbols, 0 and 1.

In a 1G network, sound waves are packaged and sent directly without any changes. If there is any obstruction during the transmission, the sound will be damaged.

To put it simply, 1g is similar to online shopping. The person making the phone call is roughly equivalent to the seller. After the goods are packed and sent out, they are no longer under his control. During the transportation process, there may be many problems such as violence, loss of goods, and contamination. Whether the goods are intact when they reach the buyer depends on the transportation process and the rigor of the package.

The 2G network uses technology to convert the original sound waves into digital data, which is then transmitted directly and restored to digital data at the other end.

In the early days of mobile phone development, it was all 2G networks, that was also an era.

The following 3G, 4G, and 5G are actually all based on digital communications.

Now is of course the era of wired communications, and we are slowly entering the wireless era.

But wireless communications also need to be based on base stations.

This is not only a major event that will cost the lives of the people and money, but it is also a national event. Xu Wengan could not have predicted it, nor did he have the courage to mobilize the country to build base stations across the country right now.

Even if you could, you wouldn't be able to reach the island.

So she only had one last option, satellite communication.

Satellites are like relay stations that can cover every corner of the earth. They amplify electromagnetic waves sent from the earth and then send them back to another earth station.

For Xu Wen, she still needs to continue her research on even the most in-depth subjects, as she doesn't fully understand them yet.

She only knew that if she had a cell phone, she could purchase the right to use commercial satellites and transmit signals to anywhere on Earth.

This way, she and Lu Yuanzheng could chat on the phone for a long time.

Now that she has come to Beijing, what she wants to do is to make a mobile phone that can receive satellite electromagnetic waves.

Xu Wen's idea is equivalent to skipping grades. There is no 1G network yet, but they want to jump directly to 2G network, and also jump from wired to wireless.

She can't do it on her own.

But there should be no shortage of talented classmates and professors in her school.

Tan Changlin was also one of her targets.

After listening to this, the skin on Tan Changlin's face kept shaking due to excessive excitement.

He also knew that what Xu Wen said was very likely to come true.

Of course, he was different from Xu Wen. Xu Wen only cared about whether the result could allow her to get through to Lu Yuanzheng on the phone.

What Tan Changlin cares about is what kind of impact this will have on the world once it is accomplished.

This must be a number of world firsts.

It is something that will also be written into history.

Although Xu Wen and Tan Changlin were discussing the same thing, their purposes were obviously different.

Sister Mulan was a little emotional. "Do you think men are born with a heart for the country? Are we just good at staying at home?"

Otherwise, why would Tan Changlin talk about the country and the world as soon as he opens his mouth?

Xu Wen just wanted to be able to call Lu Yuanzheng.

Tan Changlin glanced at Xu Wen and said nothing.

He somewhat disagreed with what Sister Mulan said. Xu Wen was also a person who cared about the country and the world. All she did were good things that benefited the country and the people.

It's just that some personal emotions are mixed in with these good things.

However, Xu Wen is indeed too low-key. No matter which scientific research has made rapid progress because of her, she will never put her name on it.

Just tell her not to mention her name.

What other reasons could there be? Isn't it that the cheater is justified because of his guilty conscience? !

Cheating in this life is, in the final analysis, cheating.

You can't use cheating grades to change other people's lives.

Whether it is wind power generation or 3D printing, including the mobile phones and satellite communications that we want to develop now, these were not invented by Xu Wen.

She didn't even know who invented it because it became so common decades later.

Xu Wen, of course, could not say what he really thought, and only said: "Everyone's choice is different. Let me give you a simple example. Some people may have an ambitious dream to change the world, while others may start by changing themselves. I am probably one of those people who thinks, 'If you can't even clean your own house, how can you clean up the world?'

I think only if I change myself first, change my family, and then change the people around me, we can slowly influence our country and even our world together.”

"Like you, Changlin, every research and every project of yours is aimed at achieving some kind of international achievement, which is true. But I want my family and I to live a more comfortable life, which is also true. A harmonious family brings prosperity, and when the family is prosperous, the people around you live a good life, and does it also indirectly affect other people and things?

Yes, I do many things to make myself more comfortable, but is the ultimate goal just to make myself comfortable? "

Sister Mulan shook her head and said, "Of course not!"

Everyone uses electricity, everyone drives electric cars, and in the future many children will use diapers.

In this sense, Xu Wen also indirectly changed the lives of many people.

The starting point is different from Tan Changlin, but the end point is the same.

Tan Changlin thought about it and felt that there was nothing wrong with what he said, so he stopped worrying about it.

I asked carefully about what he needed.

What Xu Wen wants to do cannot be accomplished by a single team.

Tan Changlin could only be responsible for part of it, but he promised to try his best to help form a team that Xu Wen wanted.

But this matter cannot be handled officially for the time being, so I’m afraid I’ll have to research it myself first.

So Xu Wen still needs to find a school here, and it would be best if he could get the school’s approval and get support from teachers and laboratories.

Xu Wen was also worried when talking about this. Her four years of college were almost over, and she didn't even know how many classmates there were in her class, let alone the professor who taught her class.

I'm afraid it's not easy to do.

But I can only wait until I talk to the principal first.

The three of them ate and chatted, and the meal took them three or four hours.

The final person to settle the bill was still Tan Changlin.

He couldn't bring himself to have dinner with two lesbians who came from far away and let them pay the bill.

Although it was Xu Wen who asked him for help, if Xu Wen succeeded in this project, he would also benefit greatly.

In short, this meal was invited willingly.

After saying goodbye to Tan Changlin, Xu Wen went to see Wang Fang again.

Wang Fang's grades certainly allowed her to enter a top university in the country.

She has changed a lot and has become much more confident.

She asked Xu Wen why he came to Beijing, and Xu Wen gave the same excuse, saying that he came to prepare to write a thesis and promote non-wet diapers.

Wang Fang volunteered to help. She asked Xu Wen to get some urine.

Sister Mulan wondered, "As a college student, who can you sell urine-proofing to?"

"Some of my classmates are married. There are also many senior students who are in graduate school. Otherwise, I can go out and distribute trial products. Anyway, it's not easy to have a job to help Wenwenjie, I will definitely do my best! I can also mobilize my classmates to help me."

Wang Fang's school was actually not far from Xu Wen's school. After sending Wang Fang home, Xu Wen took Sister Mulan to his own school.

She wants to talk to the counselor again.

As soon as they arrived at the office, the counselor stood up and pulled Xu Wen out, "You're here! Come on, the principal is still waiting for you!"

"Ah? Didn't you say tomorrow?" Xu Wen was a little confused.

"I thought the principal would be able to see you tomorrow at the earliest. When he heard you were coming, he said he wanted to see you today. I called the guesthouse where you were staying, and they said you hadn't returned yet. I was just thinking of changing my shoes and riding my bike to your guesthouse to find you!"

Xu asked: "..."

Is the principal so free?

She is a student and she can see him whenever she wants?!

Xu Wen was confused and nervously followed the instructor to the principal's office.

There are guests in the principal's office.

He is an acquaintance.

Xu Wen had seen him before on Rainbow Island, but he couldn't remember his name for the moment.
