The golden wheat fields are truly real, and they are not subject to human imagination. The wheat is almost as tall as a person, and those who don't know would mistake it for sugarcane.

The wheat stalks grew thicker and the ears of wheat on them grew better.

"Hey, hey, hey, I'm talking to you, don't move." Widow Zhang saw some people standing in front of the wheat field, and those people were trying to reach out to pick the wheat ears.

This was not the first time she had seen such people. They were always interested in the wheat and thought it was growing well.

"You guys are such idiots! We're not hiding anything. We told you we were selling culture medium earlier, but you refused to buy," Widow Zhang said. "Now that the wheat is growing well here, you want to steal it. Do you think it'll be useful as seeds?"

"We're not from here." Prince Su coughed lightly, "We just heard that the wheat here is growing very well, so we came to take a look."

"I know. You're not the first wave. People from the neighboring villages and even the town have come to see us," Widow Zhang said. "If I don't keep a close eye on it, you'll completely strip this wheat field bare. One person picking a little, another picking a little, and it'll be gone in no time."

Prince Su really didn't expect so many people to come here, and some of them would steal the fruits.

"If you like them, you can buy them," said Widow Zhang. "Pull one and you'll get a penny."

Widow Zhang calculated the prices. The best wheat and rice in town cost three or four wen per jin, while the worse ones cost two wen. People like them could only make twenty or thirty wen a day at best, but that wasn't their daily income. They needed to feed and clothe their families, and few in the village were willing to buy rice. Most people tried to find other ways to fill their stomachs.

The eldest wife of the Liu family asked Widow Zhang and others to watch over the land, and Widow Zhang had to keep an eye on it. If anyone wanted to pick the wheat, she would pay them. She couldn't let them pick it for free. That way, Widow Zhang could explain it to the eldest wife of the Liu family later.

After hearing what Widow Zhang said, Prince Su did not think there was anything wrong. He asked someone to give Widow Zhang a piece of silver. Since she was helping the Liu family's eldest branch to look after the land, they could not take those things for nothing.

"Cut two bundles." King Su ordered people to cut the wheat.

Prince Su planned to have someone sent to the capital overnight. He was the one who had someone do this and send him to the capital. As long as the Liu family is not stupid, they will not blindly think that others are good.

"This is too much silver." said Widow Zhang.

"No need to look for it." Prince Su said.

Widow Zhang heard this and simply went to get a basket of strawberries and handed it to Prince Su. Widow Zhang didn't dare to keep the extra silver for herself. She also wanted to work for the Liu family's eldest wife for a long time in the future, so she had to give the silver to the Liu family's eldest wife and tell them what happened here.

After Prince Su and his entourage left, Widow Zhang watched over the land with her family while she went to the town.

In the carriage, He Xichen looked at the wheat in surprise.

"If I hadn't seen it with my own eyes, I wouldn't have believed it." He Xichen held two wheat stalks with the ears of wheat still on them. He took off some wheat, rubbed it in his hands, and threw a few grains of wheat into his mouth.

"I haven't weighed it, but the yield should have increased," King Su said. It was obvious to the naked eye that the wheat was indeed growing better than the other wheat. The ears were longer, the grains were more plentiful, and the grains were fuller.

Prince Su was not someone who was detached from the mundane world. If he wanted to do something, he had to first do some basic homework and understand how these things really worked. A farmer's egg cost one penny, but if the chef at the palace said eggs were two or five pennies each, wouldn't that mean someone was greedy?

"Let's go to the Liu family first." Prince Su came to the wheat field first because he didn't want others to know he was here and didn't want others to tamper with the situation. After leaving General Xu's house, he went straight to the wheat field. In just one night, no one informed the Liu family, so it would be difficult for them to tamper with the situation, and it was unlikely that others would do so either.

The county magistrate here hasn't submitted a memorial to the emperor yet, probably because the wheat hasn't been harvested yet. The wheat hasn't been cut or weighed, so who can guarantee that the wheat yield has actually increased? If there hasn't been an increase, and the county magistrate submits a memorial, he would be committing a crime of deceiving the emperor.

Widow Zhang walked to the town, but no matter how fast she walked, she couldn't catch up with the carriage. It wasn't that she hadn't thought about looking for Master Zhang's oxcart, but Master Zhang had already left with the oxcart this morning.

Zhang Erye had an ox cart and knew that the vendors who bought strawberries would transport them to the county town or the prefectural capital and make a lot of money. So Zhang Erye's family simply bought some strawberries and shipped them out to sell. Now, Zhang Erye's family has tasted some sweetness and bought more to sell in the past few days.

They had heard from vendors that strawberries in the city were selling for ten coins per pound, primarily because scarcity made them valuable. The strawberries from the Liu family's main branch looked unique. The noble ladies and daughters of the city would often enjoy the best of the flowers themselves, so ten coins was nothing to them.

Strawberries that cost three cents can be transported to the provincial capital and sold for ten cents per pound. That's really a profit.

Of course, they needed a vehicle. Pushing the strawberries manually would be cumbersome unless they were very close to the city. Furthermore, the strawberries would be damaged by the hay they were using for transportation, and they would have to bear the cost themselves, not the eldest branch of the Liu family.

Those crushed strawberries can be sold at a low price and you can make some money.

The eldest wife of the Liu family often rented Mr. Zhang's ox cart before. When Mr. Zhang's family wanted to buy some strawberries to sell, the eldest wife of the Liu family naturally agreed.

The reason vendors were able to sell strawberries at high prices was mainly because they knew the housekeepers of wealthy families, so they didn't set up multiple stalls and simply delivered the strawberries directly to those families. They also delivered the strawberries to some pastry shops, which would also use the strawberries to make some snacks.

As a result, Mr. Zhang's strawberries wouldn't necessarily sell well in the city. He didn't take the best strawberries, but rather the inferior, slightly smaller ones, and used them to set up his stall. The wealthy bought them for ten cents, while the rest of the city bought them for five cents, and that was fine.

It was a little over a quarter of an hour from here to the town, and more than half an hour to the county seat, that's the time it takes to get there by oxcart. To get to the provincial capital, driving an oxcart would take more than an hour.

But no one wants to go against money, and Mr. Zhang isn't the only one in his family. He and his sons will split up and go. Today, two of them will go, and tomorrow, the others will go. This way, they can rest and not be so tired. As for the cattle, they'll bring some extra fodder to feed them.

In the Liu family's main house, Mrs. Jiang had never met Prince Su. When she opened the door and saw them, she said she would go and report to the master first.

Just then, Father Liu came back from outside with his granddaughter in his arms and saw Prince Su. Father Liu was originally a marquis, so he recognized Prince Su and quickly let Prince Su and the others into the house.

"Is this your little granddaughter?" asked Prince Su.

Prince Su had already sent people to the northwest before the New Year, and his people had already inquired about the Liu family. Prince Su heard the servants' report yesterday and learned that the Liu family had already split up. As soon as they arrived in the northwest and arrived at Shiyuan Village, the illegitimate sons clamored for a division.

Those people simply believed that the Liu family could no longer return to the capital, and that Liu Yanjing, the eldest son of the family, had injured his legs and was inconvenienced. They were unwilling to spend the extra money to treat Liu Yanjing's legs, and perhaps even wanted to cripple their legitimate brother.

The current emperor has no legitimate son, and Prince Su and the other princes are all illegitimate sons. The competition between them is very fierce. If the emperor had a legitimate son, it would not be the turn of these illegitimate sons to fight for the throne.

This dynasty pays attention to the difference between legitimate and illegitimate children. The previous princes and emperors were basically born of legitimate parents.

"Yes." Father Liu replied.

The weather today was pretty good. It wasn't sunny, and there was only a little drizzle in the morning. Father Liu went to the fields to work early in the morning. After returning, he took his granddaughter out to play. Just as he was about to bring his granddaughter back for dinner, he saw Prince Su and others.

In the yard, Liu Yulian was still fiddling with her silk threads. She had to. Who knew when her brothers would go off to the battlefield? Liu Yulian just wanted to finish it as soon as possible.

As soon as Prince Su and others arrived in the yard, they smelled the scent of medicine. They originally thought that someone was injured, but they saw Liu Yulian sitting in the yard fiddling with the silk threads, one by one.

Liu Yulian had been to the Duke of Cheng's mansion before and had met He Xichen and Prince Su. Seeing these two people, she stood up and saluted them, but her hands were still stained with medicine, so she didn't wash them, as she would have to continue.

He Xichen had someone push him in front of Liu Yulian and saw the silk thread in the wooden basin. There were several wooden basins in the yard, and they all seemed to contain medicine. The color of the medicine in each basin was not exactly the same, and some of the basins contained powder.

"What are you doing?" He Xichen asked.

"To make silk thread for armor," Liu Yulian replied. "This is the potion I'll be soaking it in today."

"Today?" He Xichen was puzzled. "Does it mean I need to soak in another potion tomorrow?"

"Yes." Liu Yulian nodded. "It has just been soaked here. One, two, three, four... eight times. Yesterday was also eight times. It will take about five days for it to be effective."

It may take five days to produce a small amount of usable silk thread, and this cycle repeats itself until there is enough silk thread.

Liu Yulian decided that after this experience, she didn't want to make more silk thread anytime soon. It was too damn difficult. Anyone who wanted to do it could do it. The success rate was so low, and it cost so much money. Who would be willing to do it if it didn't save their life?

"..." He Xichen didn't understand. Did the silk thread used to make armor need to be soaked like this? He remembered that the materials used to make armor were not soaked like this. Some of them had copper and iron sheets. Ordinary silk thread, the silk thread used to make ordinary clothes, would be cut into by a sword in an instant.

"These threads are different." Liu Yulian pointed to a thread on a railing. "You can pull it, it's very tough. You can also cut it with a knife, it won't break."

"If it can't be cut off, how do you cut it off?" He Xichen asked.

"You'll know once you see..." Liu Yulian said quietly. The threads themselves weren't very long. A long thread would have a successful section and a failed section, which could then be cut. In the end, there was basically no single successful thread left.

The attendant beside He Xichen immediately stepped forward to take the silk thread, but before his hand touched it, Liu Yulian spoke again.

"Wait, I'll get it for you." Liu Yulian said, "Just two will be enough."

Liu Yulian was not willing to give them more than a few. If they accidentally let one fly away and no one knew where it would go, she would be heartbroken. That wasn't silk thread, it was all silver.

The attendant took two silk threads and cut them with his knife, but the threads did not break. The attendant was skeptical and thought that these were just two threads slightly thicker than a hair and that they could definitely be cut. He tried twice more but failed.

Is it possible that his knife is broken?

Fortunately, there was not only one follower here, and other people tried, but still failed to cut the silk thread.

He Xichen was shocked. This thread was so resilient, it was definitely a good material for killing people. He thought about using it to cut the throat. Of course, if you want to cut the throat with the thread, you have to use force, but it does have some use.

If Liu Yulian knew what He Xichen was thinking, she wouldn't be shocked at all. Some people did that in the game, but they could just use thinner steel wire or other tools. Why would they use such expensive silk thread?

"Is the armor made invulnerable to swords and guns?" He Xichen thought of this.

"Yes." Liu Yulian nodded, and she sat down again to continue fiddling with the silk threads.

“…” He Xichen never thought that someone would make silk thread in this way.

"It takes over thirty steps, and if even one out of ten succeeds, that's already incredible," Liu Yulian said. "These medicinal liquids can't be sloppy either. They all need to be prepared according to the correct proportions. Also, when soaking the silk threads, they must be completely soaked. You can't soak the outside while leaving the inside unsoaked. Soaking them for too long won't work either."

“…” He Xichen stared at the wooden basins.

"You can do it too," Liu Yulian said. "I can give you the manuscript."

I can't be the only one spending so much money. Once you make it, you will know how expensive these silk threads are.

"I used to read some content in books and could make it with ordinary thread." Liu Yulian said.

“…” He Xichen always felt that something was wrong.

Prince Su accompanied Liu's father into the house. Since they didn't have such good tea at home, Liu's father simply asked Mrs. Jiang to bring out the roasted grass jelly taro ball milk tea she had made earlier. These kinds of dishes weren't available in the capital, and they were pretty good, considered desserts and suitable for entertaining guests.

"We don't have good tea at home, please forgive me, Your Highness." said Liu's father.

"No need for formalities," Prince Su said. "I came this time to commend you for your cotton cultivation and to see the wheat fields you've grown using culture medium. This morning, I went over there and harvested two bundles of wheat, which I had sent to the capital at full speed."

"The wheat hasn't been harvested yet." Father Liu was planning to find someone to harvest it, which would happen in the next few days.

"That's all right." Prince Su waved his hand. "It does grow differently from other wheat. After the harvest, I'll write a detailed memorial to report to Father."

"Yes." Father Liu responded.

"There's a lot of wasteland and sand and rocks in the northwest, which is a concern for my father," Prince Su said. "Every year, we have to ship food and fodder here from other places. If the fields here could produce more food, that would be great."

Prince Su read the second imperial edict from the emperor. While the emperor did intend to restore the Liu family's title of marquis, he also had no plans to allow them to enter the capital so soon. The emperor intended for the Liu family to remain in the northwest for a few more years, perhaps because he thought the northwest was a good place.

The Liu family didn't come up with these things before they were exiled, but they did after they were exiled.

The emperor thought that if the Liu family continued to stay in the northwest, even if they were restored to the title of marquis and had a large house in the northwest, would the Liu family be willing to stay in the northwest? The northwest is not as prosperous as the capital. Then the Liu family would definitely find a way to return to the capital, and they would definitely work hard to study those things.

When Father Liu heard what Prince Su said, he understood that the emperor wanted the Liu family to turn the northwest into a granary.

"The culture medium costs money." Father Liu said.

There's nothing I can do. My daughter has been spending too much money lately and there's not much money left at home.

"..." Prince Su hadn't expected Liu's father to say that. Money wasn't the problem at all. "The court will pay. This time, I've also brought an imperial edict from my father, appointing Ling'e as the Princess of Rongning County. I believe that once my father receives the wheat and I submit this memorial, the Liu family will surely be able to recover."

Father Liu understood that the Liu family's title might still be restored.

"Thank you, Your Highness." Father Liu certainly wanted to continue to be a marquis. Even if he didn't become a marquis, his legitimate son could become one.

When Widow Zhang arrived at the Liu family's main house, she knocked on the door and saw Mrs. Jiang. Widow Zhang had originally wanted to tell Liu Yulian and others about someone using a silver ingot to buy wheat, but who would have thought that she would run into those people here? She could tell that the people from the Liu family's main house knew them.

"Young lady," Widow Zhang said, still smiling, as she stepped forward, "What a coincidence! They just went to the wheat fields and spent this money to buy two bundles of wheat. So, I quickly gave the silver to you, young lady, to prevent me from losing it."

Widow Zhang didn't say anything else, just let the people in the Liu family's main branch know the situation.

Liu Yulian asked Widow Zhang to put the silver aside first, took out her purse, took out a piece of silver and gave it to Widow Zhang, "In two days, we will harvest the wheat and plow the land."

"Okay." Widow Zhang took the silver and left. There was work to do at home. Since they had a large family, they could easily assign some people to continue working for the Liu family's eldest wife. Widow Zhang's wheat was almost ready for harvest, mainly because they used the culture medium later, which was why it was slow.

Other people's wheat had also grown ears, and they were still wondering if using culture medium would be useful at this time. When they realized that using it at this time would not increase the yield much, they did not plan to buy culture medium anymore, but decided to use it when they planted new crops.

At noon, Prince Su and He Xichen stayed in the Liu family's main house for lunch. Liu Yulian also cooked two dishes, and the other dishes were made by Mrs. Jiang and Mrs. Xie.

Liu Yulian was naturally in high spirits when she learned she had been named a county lady. As soon as she was happy, she took out the books she had copied earlier on how to make invulnerable silk thread. Each step, including the materials, steps, and time, was recorded in three relatively thin books.

Liu Yulian didn't draw any pictures or write down the names of the herbs. Just the names would have been enough. If someone else had added pictures, the book would have been even thicker.

"The herbs aren't expensive, but the failure rate is high." That means it costs a lot of money, Liu Yulian said, "We have to test each one individually."

"It's a waste of money." Father Liu said bluntly, "She spent all the money she earned from selling embroidery, selling strawberries at home, and other money she had."

"Life is more important than money!" Liu Yulian emphasized, "Besides, how can you say that Huo Huo died? The armor he made wasn't for me to wear!"

If we talk about Huo Huo, let’s talk about brother Liu Yanjing’s Huo Huo, and also He Xiyuan’s Huo Huo.

"It can be considered as Yuandi Huohuo." He Xichen saw Liu Yulian glanced at him. Liu Yulian was his brother's fiancée. "You will be a family sooner or later. His things will be yours sooner or later."

"..." Liu Yulian was silent. Didn't He Xichen plan to take out some silver to show his appreciation?
