It was the end of the first lunar month when Prince Su and his entourage arrived in the northwest. The capital was a long way away, and Prince Su had deliberately set up a trap along the way, either to kill or capture alive those who were trying to assassinate him.

Prince Su is very capable, otherwise, how could he become the old emperor's candidate for crown prince.

This northwest incident was of great importance. The emperor had deliberately sent Prince Su here to further enhance his reputation among the people. Prince Su had only seen ordinary wheat along the way, and the Liu family's eldest branch wasn't here. It was unlikely that anyone from elsewhere would have used that culture medium, and it likely hadn't been leaked.

At the Xu family, Prince Su and He Xichen arrived first. Madam Xu was He Xichen's aunt, but not related to Prince Su by blood. Because Prince Su's mother, the Imperial Concubine, and the wife of Duke Chengguo were sisters, Prince Su was quite positive about the Duke Chengguo's residence and thought it would be a good idea to come to the Xu family.

Before that, it was General Xu who submitted a memorial to the emperor about the recipes given by the Liu family.

General Xu wasn't one to seek credit; his submission was itself a merit. If he took all the credit, the emperor wouldn't believe he had developed those findings. If he claimed his children had developed them, would the emperor allow him to continue research?

Truth will eventually come to light. It would be better to tell the truth and save the Liu family.

Prince Su came to the Xu family to ask General Xu about the situation and what the things given by the eldest wife of the Liu family were like.

"There's a universal version of this culture medium, which is used for some common crops, but it's not as good as the targeted culture medium," General Xu said. "Right now, people are using the universal version, and those vegetables do grow faster and better."

General Xu went to check on the crops several times, and the servants had indeed not lied to him; the crops were indeed growing well after using the culture medium. General Xu planned to use the culture medium when the spring wheat crop came out; he was worried about running out of food and fodder while fighting outside.

The imperial court would indeed provide them with food and fodder, but sometimes there simply wasn’t enough of it, and the soldiers had to cultivate some of their own land.

General Xu thought that since the culture medium could be used, he could use it. By then, he could harvest more wheat and the soldiers would be able to have more to eat.

"The Liu family grows a lot of wheat," General Xu said. "I heard they've been selling strawberries lately, and some people are buying them and taking them to the capital to sell."

"Have you met General Xu?" asked Prince Su.

"I haven't seen them, but it's not like I'm watching them every day." General Xu coughed lightly. "I took a look at the wheat fields earlier, and they're really growing well. Winter wheat shouldn't be harvested so quickly, but the wheat grown with culture medium is almost ready. If Your Highness visits in the next few days, you should still be able to see wheat growing in the fields."

"Let's go and take a look tomorrow." said Prince Su.

Prince Su didn't know what the wheat grown by the Liu family was like, but since General Xu said so, the wheat grown by the Liu family should be good.

There are always some geniuses in this world, and no matter how hard others try, they can never reach their intelligence. It would be best if Liu Yulian really is a genius, then the engagement between He Xiyuan and Liu Yulian would be secure.

The eldest wife of the Liu family didn't know anyone was coming to see their wheat fields, so Liu's father paid some people for their work. The land that the eldest wife had bought near the town had been reclaimed and was now being planted with crops.

Liu Yulian couldn't possibly produce so many saplings at once; she mostly just took seeds. She'd buy some at the store, then substitute the better seeds from the space. This would save her the time of cultivating new varieties, saving her several years, even decades.

"I think it might rain today. If it rains tomorrow, it will be difficult to work. If the rain is lighter, it will be okay." Father Liu said. It is not suitable to work on rainy days, and others cannot be asked to work in the fields. If they get sick, the wages will not be enough to pay for medical treatment.

"Let's see tomorrow. If it doesn't rain and someone comes to work, then we'll do it. If it rains, then don't do it." Liu Yulian walked into the yard and looked at the dark clouds in the sky. "I hope it doesn't rain all the time."

If it rains constantly, they won't be able to irrigate the culture medium, as the liquid will be easily washed away by rain, so they'll have to use solid fertilizer.

Liu Yulian entered the room and took out the cotton thread she had soaked in a special liquid. She also wanted to make her brother invulnerable armor. Fortunately, she had a lot of cotton left over, otherwise, he would always fail. It was really difficult.

There are so many steps involved, and either one step fails or the other fails.

If you fail too many times, you will become numb.

The main thing is that if you fail in the game, you can throw the keyboard. If you fail in real life, you have to keep doing it like in the game until you succeed.

Liu Yulian made the silk thread first, instead of weaving the armor first. If she wove all the silk threads first, the success rate would still depend on the silk thread. Don't let some of the silk threads of the armor work, but some don't, then it won't be able to stop the sword.

Liu Yulian wasn't that stupid. Someone had done that in the game before. The probability of successfully making all the silk threads of an entire piece of armor was too low. Armor made that way would be a defective product. Only armor made from the silk threads would be truly invulnerable.

Since such silk threads are so rare, some people use ordinary silk threads to clamp them on both sides with a low spacing, thinking that the probability of protection will be higher.

It's okay to do that in the game, since you can revive unlimitedly and the cost is low.

It won’t work in reality. If something really happens, it will be too late to regret.

Therefore, Liu Yulian didn't dare to use ordinary silk threads to make such armor. It had been more than half a month since she started to make those silk threads, and she still hadn't finished all the silk threads. She could only make two small bundles of silk threads, and she had to make a few more bundles.

Armor woven from this silk thread can be very thin, but it is very powerful.

Both Liu's father and mother knew that Liu Yulian was researching some kind of invulnerable silk thread. Such silk thread was not easy to cut, was very tough, and was very soft, and could be easily bent into various shapes.

If they hadn't seen Liu Yulian successfully make two small bundles of silk threads, they wouldn't have dared to believe it.

"Failed again?" Mother Liu looked at Liu Yulian who was picking up silk thread with a thin bamboo stick. Her daughter had failed many times and had used up a lot of herbs and other plants.

Those things cost money, and Liu's mother felt a little distressed. But when she learned that the silk threads were invulnerable to weapons, she asked her daughter to continue researching. If she succeeded, it would also keep her son safer.

"Some succeeded, some failed," Liu Yulian said, "We have to pick them one by one."

This is how the game works. Not all threads you try will fail; a small percentage might be successful. Players have to pick them out one by one, using the in-game appraisal technique. Appraising high-level items costs copper coins and ingots, effectively spending RMB.

Liu Yulian is now picking out those silk threads, mainly by hand. This is not a game, and there is no identification technique.

Not within the service area...

What else could Liu Yulian do? She could only identify the silk thread herself based on its characteristics. She thought back to when she used to save a few coins playing games, constantly clicking the mouse to make the game character perform various actions to identify things. It was truly too difficult.

"I have to pick them one by one again." Mother Liu looked at the books placed aside. Her daughter had read a lot in the past and her memory was good. She didn't know where those books had gone. After all, the Jingning Marquis's Mansion had been confiscated, and even if there were any rare copies, they would probably have been thrown away or burned.

In the eyes of Liu's mother and others, Liu Yulian relied on memory to write down those things, and some of them had errors, and the success rate was too low. When they saw their daughter preparing the culture medium before, the success rate of the culture medium was very high, and it was basically successful.

In the game, the probability of synthesizing some things is 100% success rate.

The culture medium prepared by Liu Yulian has a very high success rate. As long as you follow the relevant steps and don't change the steps at will, the success rate will be high.

"You have to pick them one by one." Liu Yulian nodded. If you don't pick them one by one, what else can you do? The finished silk threads can't just be soaked in those potions forever. After finally reaching the last step, you must not commit suicide at this time. You still have to pick out the silk threads that have been made successfully.

Liu's mother didn't know what the silk threads were like, and she was afraid she'd pick out the wrong ones. So she moved a chair for her daughter to sit on, letting her carefully select the threads. The threads were incredibly thin, almost as fine as a human hair.

"Staring like this will make your eyes blurry." Liu's mother sighed.

"Even if my eyes are blurry, I still have to choose." Liu Yulian joked, "Once the armor is finished, if I sell it, it will definitely fetch a high price."

"You said the price was high, but you put all the money you earned from selling strawberries into this," said Liu's mother. "And how much did you put into this from your embroidery?"

Liu Yulian looked at the thin thread in the basin and said, "That's worth it."

"It's worth it. It can save lives, so why wouldn't it be worth it?" Liu's mother didn't stop Liu Yulian because the armor made of silk threads could save lives, and also because the money was originally earned by Liu Yulian. "If others see you going through so much trouble... But it's okay. As long as it succeeds, and it's not just yours, then it can't be considered a crime to possess a treasure."

Liu's mother thought that ordinary people would not be able to make this kind of silk thread, and only the powerful and wealthy could find a way to make it. This kind of silk thread is not easy to make. Liu's mother watched Liu Yulian waste many pages of paper writing and constantly correcting her, and now she has barely come up with a decent method.

But there are hundreds of herbs and other ingredients needed for this. Not to mention the question of the right proportions, whether to soak in cold water or boiling water, and how long to soak...

Mother Liu felt a headache looking at those papers. She didn't know how her daughter remembered those things.

"Yes." Liu Yulian nodded. "I copied them all and bound them into a book."

"It has to be bound into a volume, which is as thick as several books." Mother Liu thought that the paper placed next to it was only a part of it. With so much content, it was only possible that it was written and revised day by day.

Some of those papers were scribbled on in many places. The ones Liu Yulian brought were scribbled on in various places, and she wanted to keep improving them.

"If I print them out and sell them, can I make money?" Liu Yulian couldn't help but think so. You know, these silk threads are too expensive, they are gold-swallowing threads.

If Liu Yulian hadn't done it before in the game, and the system had given the names of the materials for the steps, her success rate probably wouldn't have been so high. If it were someone else, they would probably have failed numerous times. Making a piece of armor like this would cost at least several thousand taels of silver, and at most tens of thousands.

But this amount of silver is not particularly much for those powerful families, and they can still make one or two pieces of such armor.

"Who would buy a book like this? I'd rather see if the rich buy it than not." Mother Liu said, "It's just a book, and they don't know if it's real or not, so there must be few people who buy it."

"..." Liu Yulian was silent. This was the cruel reality. She continued to pick the silk threads, trying to prepare them as soon as possible.

These silk threads cannot be wasted. Instead of cutting them directly into a large piece of cloth, they have to be used on armor, all of which are made into certain shapes, just like knitting a sweater.

After Liu Yulian sorted out the silk threads, she placed them on bamboo poles. They were still damp and needed to be dried. The threads were very light and could be blown away by a gust of wind. They couldn't be dried over a fire; it was best to air dry them.

"By the time you finish getting all the silk threads, the wheat will probably be harvested." said Liu's mother.

"Dad, keep an eye on it." Liu Yulian continued to work hard with the silk threads with her head down. She couldn't be impatient and had to look more carefully so as not to miss a successful silk thread.

Liu Yulian hadn't been going to the fields that often recently; it was mainly her father who went. Old Jiang drove the ox cart with her father, and he knew to ask Village Chief Zhang if he could help find some work.

In this way, Father Liu can relax a little and not be so tired.

The lamps in ancient times are not the lamps in later generations. Just because Liu Yulian has full life skills doesn’t mean she can make lamps, nor can she generate electricity.

Liu Yulian could only quickly pick out the threads. If she left the threads in the potion overnight and came back to work on them tomorrow, many of them might be ruined.

If you can only make a dozen out of a hundred long threads, that's already very difficult. Some threads can be made halfway, but if they can't be made halfway, they have to be cut.

"Brother, you must protect me more in the future." Liu Yulian curled her lips.

"You are so attentive, how could your elder brother not protect you?" Mother Liu said with a smile, but unfortunately she could not help.

Seeing her aunt sitting there, absorbed in selecting silk thread, little Liujia didn't dare approach too closely. She had previously wanted to help her, but she was stopped by her aunt. Her grandmother had also gone to play nearby, and when she disobeyed, she was spanked.

This made Xiao Liujia afraid of those silk threads and she didn't dare to move forward casually.

"Come, grandma will take you to find something to eat." Mother Liu took her granddaughter's hand to prevent her from disturbing her daughter while she was picking silk thread.

After nearly an hour of painstaking work, Liu Yulian managed to pick out a small handful of usable threads. The rest were wasted and could only be used as ordinary silk threads. During the first process, a large bundle of threads became a small bundle by the last, and most of the threads in that small bundle were failures.

With so little silk thread, Liu Yulian didn't dare to put the bamboo pole outside. She could only put it in a ventilated place in the house and open a window. It was really difficult for her to prevent the silk thread from being blown away by the wind.

Game developers are not human beings at all, they are just emotionless money-making machines.

It seems that the medicinal materials are not very precious, but there are failures in every process. Sometimes it is impossible to tell which silk threads have failed in the previous processes, and those failed silk threads have to continue to soak in the medicine.

Game developers are like that. If you want to know in advance, use the identification technique.

In the end, players can't tell whether they're spending more money on appraisal or letting failed items continue through other processes. At most, players want to wait until the end to have everything appraised, so why not? But appraising every step would be a massive undertaking. Developers are the devil!

"It's ready." Mother Liu asked Mrs. Jiang to cook chicken noodle soup. She placed the noodles in front of Liu Yulian and said, "Eat some."

My daughter has been busy picking out silk threads since she finished her dinner early. She must be hungry.

Liu's mother still knew how to have someone cook for her daughter, and she had chicken soup noodles with a poached egg.

"It will take about a month." Liu Yulian said, "Fortunately, there are still many herbs here, so we can buy them."

"I was just saying that. Doctor Shi also asked you if there was anything going on at home and what you were going to do." Mother Liu smiled and said, "You've been to several herbal medicine shops in town."

"They don't buy much." Liu Yulian shrugged helplessly, "We can only look at more of them. They use them to make silk thread. It's not a secret that should be revealed."

When Liu Yulian went to buy herbs, if someone asked her, she would say it, and if no one asked her, she would not say it.

At the beginning of a new day, Prince Su and He Xichen did not go directly to the Liu family, but went to Shiyuan Village first. When they arrived in the village, they asked someone where the land of the Liu family's eldest house was, as they were going to buy strawberries.

"Their strawberries are really good," said the villager. "The wheat is also good, golden and ready to be harvested."

The villagers were filled with regret when they thought of this. Why didn't they buy the culture medium like the widow Zhang's family did? If they had bought it, they would have harvested a lot of wheat by now.

Unfortunately, their family didn’t buy it, so now they can only drool at other people’s wheat fields.

Some people wondered if it was too late to buy culture medium and if they could increase production. If they could, that would be great.

"Just go this way. When you see the tall, golden wheat fields, the strawberry field is right next to it," the villager said. "Widow Zhang's family is guarding that strawberry field. The Liu family's main branch isn't here. If you want to buy strawberries, you can ask Widow Zhang. There's a road over there, and your carriage can pass through."

Widow Zhang was not very literate, but someone in her family had read books and could record things. So she told her grandson to write it down and not to think about taking advantage of others. If you take advantage of others at first, you will want to take advantage of others later, and if you take advantage of others more and more, you will not be able to turn back.

"Okay, then let's go and take a look." said King Su.

The eldest branch of the Liu family wanted to sell strawberries, so they had a road built. The road is quite wide, but it is not easy to push a wheelchair. It is more convenient to take a horse-drawn carriage.

He Xichen was sitting in the carriage, accompanying Prince Su to see the wheat field to see if the wheat there was really growing so well. If the wheat field was really good, the day when the Liu family returned to the capital would be just around the corner.

"Let's go and take a look." Prince Su got on the carriage. If He Xichen hadn't been there, he would have walked over directly. He Xichen was unable to move around easily, so they took the carriage over.
