Chapter 144

Luo Zemin shook his head: "If it's not enough, we can only consider combining them in sections. For example, if two sections are put together horizontally, it will be 20 meters long, and if two sections are put together vertically, it will be 10 meters high."

Xu Wen pursed his lips, "Can it be as strong?"

Tan Changlin interrupted: "You can consider leaving gaps when designing. Just like playing with building blocks, leave slots, and after the two sections of the wall are put together, fix them with welding or other methods."

"You know where I'm going to use this thing. That environment doesn't support welding." Xu Wen disagreed. Who can play with fire on the seabed?

Luo Zemin said confidently: "Believe me! No matter who you ask, it cannot change the fact that this number is the limit of the printed wall. If it is higher or longer, it cannot be guaranteed to be strong.

Do you want to build a building? To be honest, if you want to build a building, our current technology is not capable of that. Generally, the height of one floor of a building is about three meters. I mean one floor.

We can only print one layer, and the rest needs to be connected manually. It is difficult, and the cost saved also goes up.

The most important issue is quality, which we haven’t tested yet. But I personally think that the quality may not be comparable to that of man-made buildings.”

Xu Wen shook his head: "It's not building a house. But it's almost the same idea."

Tan Changlin comforted Xu Wen: "This is already the best and fastest way."

Xu Wen didn't say anything.

If the purpose is simply to expand Rainbow Island, this size is indeed no problem.

A little bit at a time.

But any ship that can become a battleship is more than 100 meters long.

Lu Yuanzheng said that the vehicle parked at the door of his house was 177 meters long.

This means that the length of light has to be spliced ​​into seventeen pieces. Who knows how many storms the spliced ​​parts can withstand?

However, Xu Wen thought again, what use is a wall in front of a huge ship like the Kaya? Even if the Kaya cannot use its strength at close range, the heavy weapons on the light ship will be destroyed in one go, so this has no practical significance for the Kaya.

On the contrary, if they built a flimsy wall and it was destroyed by the Kaya, could they be charged with provoking trouble and intending to start a war between the two countries?

Thinking of this, Xu Wen breathed a sigh of relief and asked Luo Zemin: "Can the length be adjusted?"

"It can only be shorter, not longer. Within the longest and highest ranges, the size can be adjusted at will."

Xu Wen nodded, "That's enough! How long will it take to finish it?"

"The earliest will be next week."

"It's actually pretty quick here. Mainly because I saw the list of raw materials you gave Brother Xu. Some of the raw materials you requested are very rare and hard to find internationally. Brother Xu certainly couldn't find them for you, so I had to ask a lot of people for help before I could buy them. They're on the way now, but it'll take a few more days to get them here."

"No rush." ​​Xu Wen asked. There was no point in rushing.

Tan Changlin, who was standing next to him, was attracted by a rectangular block in the corner. He pointed at it and asked, "What is that?"

Luo Zemin looked back and said, "A 3D printer!"

"Can I see it?"

"Of course."

Tan Changlin rubbed his hands and walked over, and Xu Wen followed him curiously.

"This is what a normal printer should look like!" Tan Changlin half bent over and looked down to examine it carefully.

This printer is about one and a half meters long and fifty to sixty centimeters high. It is currently working, probably printing a red round cup.

There are several similar models lying on the ground next to it, and it can be seen that they have gone through a process from rough production to increasingly sophisticated debugging.

Tan Changlin sighed twice, then lowered his head to carefully examine its working principle.

This printer is considered a finished product, but for the convenience of debugging, the surrounding protective panels are not installed, and the components inside can still be clearly seen.

The plastic used for printing is like a long wire, but the wire is insulated outside and has a copper core inside. This is just a solid red plastic wire.

One end is connected to the print head, and after heat treatment, it runs along the predetermined track little by little, and then a cup is slowly printed out.

It's really slow! If we continue to produce at this speed, we will be on the verge of bankruptcy. There is still room for improvement.

Xu Wen also smelled a pungent smell of melting plastic.

Luo Zemin chased after him and smiled at Xu Wen a little embarrassedly, "Sorry! I used your research without your permission. I just wanted to make a more normal printer to test it."

Xu asked: "..."

Her printer isn't working properly?

Luo Zemin saw the protest in her expression and said quickly, "That's not what I meant. I meant to make a small and convenient test."

Xu Wen certainly didn't take it seriously, he nodded and praised him: "You are amazing! You can draw inferences from one example and do it very well."

Luo Zemin is much more powerful than Xu Wen expected.

Moreover, even a small cup requires a model program. In that era when computers were far from being popular, whether Luo Zemin asked someone for help or did it himself, it was extremely amazing.

Either their connections are strong or their own strength is strong.

Luo Zemin waved his hands, "This is all made with the drawings and data you gave me. You are the amazing one!" He raised his wrist to check his watch, "It looks like you still have some time. It's too hot here, shall we go somewhere else to talk? I know a dessert shop that makes delicious cold drinks and cakes."

Xu Wen hesitated for a moment, but finally nodded. It was really too hot here in Luo Zemin.

Luo Zemin mainly discussed cooperation with Xu Wen.

He wants to use Xu Wen's 3D printing technology to start a business and specialize in 3D printers.

To start a business, one must first get the factory running. As he could not afford to pay Xu Wen's copyright fees, he discussed with her about letting her invest in the company through technology.

As long as Xu Wen agreed, he would go back and apply for a patent immediately.

Regardless of success or failure, Xu Wen will be given 20% of the shares.

Of course Xu Wen is very optimistic about 3D printer technology and also about Luo Zemin as a person.

The key to being brave enough to work hard and to be flexible in thinking is to not forget your roots.

So Xu Wen agreed.

Luo Zemin wrote a handwritten letter of commitment to Xu Wen, saying that he would give her a formal contract once the factory registration procedures were completed.

Tan Changlin was not there when we talked about this.

I don’t know if it was out of politeness or because he really didn’t like desserts, but when we arrived at the door of the dessert shop, Tan Changlin said he still needed to buy some daily necessities and left first, and made an appointment with Xu Wen to meet at the pier.

After Xu Wen negotiated the relevant matters with Luo Zemin, he took a detour to say hello to his second brother before setting off back to Rainbow Island.

Tan Changlin was already waiting for her at the dock, carrying his daily necessities in his hands.

Just a piece of soap for washing clothes.

Only then did Xu Wen realize that he was just leaving a space for himself and Luo Zemin to talk.

It turns out that his emotional intelligence is not as low as he appeared before.

Return to Rainbow Island.

As usual, Xu Wen stopped in front of the Kaya and distributed some of the fruits and vegetables he bought from Pengcheng to them.

They gave the money to Xu Wen as usual, but this time, the officer named Custer took the initiative to greet Xu Wen: "Beautiful lady, thank you! But you better not give me any more in the future."

Xu Wen was a little puzzled, "Why?"

"Then why do you insist? From what I understand, this is very disadvantageous to you, isn't it?"

"You should also know that my husband is also a soldier. I know that he has a hard time when he is away from home! When I see you, I will think of him. I just want to be nice to you and do good deeds. If one day in the future my husband is forced to be trapped outside and can't return to the country or home, there will be someone who can give him a little warmth. That's all, there is no benefit or disadvantage!"

Everyone on the Kaya who heard these words was moved.

In addition to being soldiers, they are also sons, fathers, and husbands, and their families are also thinking about them at home.

Especially because of their special profession, they are trapped here and their families are completely unaware of it.

Custer hesitated to speak and finally just said thank you.

Although he didn't know what happened, the other party took the initiative to speak up, and spoke in a caring tone, which was a huge breakthrough for Xu Wen.

During dinner, Xu Wen mentioned this matter to Lu Yuanzheng.

The journey is long and he frowned, lost in thought.

Seeing that his expression was not right, Xu Wen wondered, "What's wrong? Is there something wrong?"

"There is only one thing going against you in your approach to them right now."

"Yes, my sisters-in-law misunderstood me." Xu Wen interrupted subconsciously, and his expression became serious after he finished speaking.

How did these officers and soldiers trapped on the Kaya know about what happened on the island?

"Are there spies?" Xu Wen said, then shook his head to deny it. "There are currently no ordinary people on this island. They are either soldiers or their wives and children. At the very least, they are elites like Tan Changlin who work in state-owned units. There can't be spies."

Lu Yuan raised his eyebrows, "People doubted you, but you were generous and believed them unconditionally."

"If I were to be like them, wouldn't that make me look ignorant?"

"That's right! My wife is the smartest." Lu Yuanzheng said as he put down his bowl and chopsticks. "My dear wife, go home after you finish eating. I have a meeting to attend."

"You're not full yet!" Xu Wen pointed to the bowl in front of him.

Generally, they would not waste food when on a long expedition, and no matter how much food they collected, they would not leave any leftover.

There is still half a bowl of rice in Lu Yuanzheng's bowl.

"Everyone has heard our conversation, how can we eat? I have to report this. Or you can take it back for me and I will eat it in the evening when I get home."

Things have different levels of urgency.

If the enemy can get tea to the island, it will be much more serious than wasting a bowl of rice and we can't afford to delay.

In the end, Xu Wen finished the meal.

She said that she would be his strongest support, and she would do what he couldn't do.

That night, the journey was long and the journey ended without return.

The next day, their red and blue confrontation continued. If you look closely, you will find that many ships are missing.

The journey is long and the expedition is not yet over.

Xu Wen was eating breakfast when Lu Yuanzheng came back in a hurry and asked her, "Wife, do you know how to completely prevent noise?"

"Ah?" Xu Wen blinked. "Sound gun? You mean they brought sound guns? But sound guns can only detect objects and can't eavesdrop on conversations, right?"

Shengna Xu Wen knew it.

This is also often used in the military, such as torpedoes and submarines.

But the sound cannot be eavesdropped, and no matter what the sisters-in-law say to her, she should not be able to hear it.

Lu Yuanzheng pursed his lips and said, "It wasn't heard by the sound machine. It should be that the sisters-in-law were playing at the beach and saying bad things about you, and the people who came to place the sound machine happened to hear it."

Xu asked: "..."

It took her a while to digest this information.

"You mean they left the Kaya? And installed a sonar device here? But weren't our officers and soldiers always monitoring them?"

"We found several containers on the seafloor last night. They contained acoustic equipment. One of them was not far from the sea where you usually play.

I suspect one of their people sneaked out and set it there.

As for surveillance, we have people on patrol so there will be some negligence, not to mention they can avoid our patrols if they can help." Lu Yuanzheng looked unhappy.

If there is a sound, it is very troublesome.

At least it is unrealistic for frogmen to get on board the Kaya from the bottom. In fact, no living creature can approach the Kaya unknowingly.

This will make Lu Yuanzheng and the others become very passive.

As far as Xu Wen knew, there was no complete sound shielding technology before she came here.

The few types she knew, Lu Yuanzheng and the others also knew.

"Can't we use this as an excuse to fire them away?"

Lu Yuanzheng shook his head. "We have no evidence that they did it. There are no obvious markings on any of the equipment. As long as they refuse to admit it, there is nothing we can do."

Xu Wen thought about it for a long time, and the few methods he knew of were either technically unachievable or were known methods with little effect.

Seeing that Xu Wen had no better suggestions, Lu Yuanzheng told her to keep it a secret and not let the other sisters-in-law or children know about Shengmi, and then left in a hurry.

If it weren't for the fact that Xu Wen had seen a lot and wanted to know if Xu Wen had any solution, he wouldn't have told Xu Wen.

This question was also asked at the instruction of Song Xueqin.

The sonic technology is really hard to crack, which makes Rainbow Island very passive.

Xu Wen knew that this time, no matter what he said, he could not let the Kaya stay here.

Song Xueqin and other officers and soldiers from the other islands arrived at Rainbow Island and held meetings all day.

It's easy to guess that they were discussing how to bomb the Kaya.

In the evening of the next day, Xu Wen brought a lot of dairy products and fruits to comfort the officers and soldiers on the Kaya.

The sentries on the Rainbow were already used to it, so they weren't scared when they saw Xu Wen appearing.

They all thought that Lu Yuanzheng was also on the houseboat.

Just like yesterday, Custer was much friendlier to her.

Xu Wen took the opportunity to ask to see the Kaya.

As expected, Custer refused with a defensive look on his face.

Xu Wen didn't leave, nor did he try to persuade them. He just sat on the deck of the houseboat, looking as if he was about to cry.

Custer: “…”

After a while, Custer said, "This is a military ship. No outsiders are allowed on board."

Xu Wen blinked and shed a tear.

She calculated the angle carefully; the tears must have fallen slowly from her eyelashes, rolling from the corner of her eye to the edge of her lips.

This is something she has rehearsed many times in front of the mirror, and even she herself is particularly moved when she sees it.

Lu Yuanzheng only saw it once and warned her not to use the beauty trap.

Xu Wen looked pitiful, his eyes clear and innocent: "But here, you can visit military ships. I've been on them. Could it be that your ships are so simple or the technology is so low-end that even an ordinary citizen can understand them at a glance?"

Custer shook his head: "Impossible!"

It is not possible for an ordinary woman to study any warship thoroughly with just one look.

They had heard a little about Xu Wen's identity, and also vaguely heard what the people on their island were scolding her for.

Custer's adjutant thought of this and had an idea: what if Xu Wen could really be bribed?

The idea made him somewhat excited.

If I could really get the other party's chief officer's wife to be my undercover agent, then...

Custer's adjutant whispered his thoughts to Custer.

Custer frowned and disagreed: "How can you take advantage of a woman? Especially since she is so friendly to us!"

The adjutant continued to persuade him for a long time, and the gist of what he said, if translated into Chinese, is nothing more than that people who achieve great things do not care about trivial matters, and so on.

Anyway, Xu Wen is just an ordinary citizen. What’s the difference between allowing her on board and allowing many visitors from other industries on board in the country?

Custer had better be persuaded.

Staying on a boat for a long time is actually a very psychologically demanding experience.

In particular, in order to avoid exposing their own numbers, they only allowed a few people to take turns going up to the deck for fresh air every day.

The cabin doors were too depressing and the food was monotonous.

The fruits and vegetables that Xu Wen delivered every day were definitely not enough for the entire ship’s population and could only be given to the sick patients to taste.

If you can make use of Xu Wen and complete your goal and go home earlier, it would still be worth it.

After thinking about it, Custer agreed and said that only one person would be allowed on board and that he would need to be searched.

Xu Wen didn't expect that he could convince them so easily. He was stunned for a moment, and then he felt scared.

There were at least three digits of officers and soldiers on that ship.

What would happen if she was the only woman on board?

What if I get raped... No, even if I get restrained it would be a problem.
