Hand over the jade seal first [Infrastructure]

Yes, firecrackers.

At the beginning, Xiao Zirong said that he didn't want to participate in this matter, but he still handed over some materials to Taoyuan City. Later, he didn't take care of it. Occasionally, he would answer some unsolvable problems there, but more often Just let those people do their own research.

There is no way, Xiao Zirong can only rely on the library. When he wants to do something, he needs to find materials first, record various key content, and then hand it over to the people below when he understands it. Guarantee that problems can be solved after encountering them.

If it's the knowledge point that he didn't understand thoroughly, then I'm sorry, you can figure it out yourself.

Xiao Zirong is not really a god who knows everything, he also has to study to understand.

It is true that the years of being a Piao in the library have enriched his knowledge reserve, but it is not that comprehensive.

The firecracker was independently researched by Taoyuan City. Whether it is stuffed with gunpowder from the front or needs to be ignited separately, it shows that this thing is backward. If it was Xiao Zirong, he would definitely not make such a backward thing.

But it was enough to make him feel that these people have really made rapid progress, and he originally thought that they would come up with artillery first. After all, artillery is big, and it must be much easier to make than firecrackers.

In the end, I didn’t expect to make the firecracker first, and the reason given by Zhai Xi was: the firecracker was originally made as a model of a cannon, but after doing it, I found that the firecracker was more portable, so I made it first. firearms.

Chai Shuren and Xie Junsheng next to Xiao Zirong looked at the firecracker and their eyes lit up: "Your Highness, this thing is ready to go to the battlefield?"

Xiao Zirong said: "Reluctantly, there is still a danger of bombing, and there is still a lot of room for improvement. I will still write a letter to Zhai Xi later."

After finishing speaking, Xiao Zirong sighed, how can he really not care about it, he now suspects that the reason he brought the fireworks to Wei State was to continue researching thermal weapons without any burden.

After all, the state of Wei already has gunpowder, so the state of Qi must naturally stay ahead, or it will be invaded.

As a result, that trash Yuan Ke hasn't produced gunpowder until now!

Looking at the expressions of Chai Shuren and Xie Junsheng, Xiao Zirong couldn't help but smiled and said: "It's not that I don't want to play with you, I'm afraid that if the chest explodes and directly hurts my left and right arms, what should I do? Don't worry, I will give it to you when the upgraded version comes out later." You play."

However, it is not allowed for individuals to own guns, and guns must be strictly controlled.

Thinking of this, he felt that he needed to write a letter to Xiao Xuexing to bring the gun control laws to the court for discussion. This should be no problem.

After all, if the control is not strict, ordinary people can also hold guns. At that time, everyone will be unsafe, and people can be assassinated from a distance. This thing is more convenient to carry than bows and arrows.

Xiao Zirong threw this idea away in his mind for a while, then turned to Chai Shuren and asked, "How is the wool?"

Chai Shuren said: "It has been cleaned and brought in, Your Highness...you...do you really want to do it yourself?"

Xiao Zirong waved his hand: "Don't worry, I will let the palace servants do it, I won't do it myself, it's just that there are some procedures that others don't know how to do."

If the illiteracy rate is low, he can write down all the steps, but the problem is that even in his palace, most of the palace people are illiterate, how can Xiao Zirong not keep an eye on it?

The weaving of woolen cloth is completely different from the making of woolen carpets. The carpet does not need to grow wool, as long as it is woven and cut to the same length, but woolen cloth is not.

And people nowadays don't seem to know the difference between wool and cashmere, so Xiao Zirong has to have people pick out the cashmere. Clothes made of cashmere are lighter, thinner and warmer, and can be made into close-fitting clothing.

Wool is almost as good as a coat.

It just so happened that the matter was almost negotiated, Xiao Zirong drove away the two greedy people, then turned around and ran to the place he had allocated before, which was a place where he specially asked people to make wool.

Liu Cainiang followed Xiao Zirong and said helplessly: "The backyards of other princes and kings are all Yingyingyanyan, surrounded by beauties. Your Highness's backyards are all separated and become experimental sites."

Liu Cainiang is worried, her highness is good everywhere, good-looking, good-looking and smart, even if she keeps herself clean, she can't be without someone around her, right?She knew that even Ayin Aman was not confiscated.

Yes, Liu Cainiang still doesn't know the relationship between Xiao Zirong and Xiao Xuexing. It's a coincidence that when Xiao Zirong celebrates Xiao Xuexing's birthday, she needs to sit in the palace, and when Xiao Xuexing came over, she went out to Taoyuan for Xiao Zirong city ​​delivery.

Well, what was sent was information about firearms, and Ayin Aman was told in advance not to expose this matter casually, it seems... quite obedient.

So now Liu Cainiang still thinks that Xiao Zirong is single. Of course, if she knows who Xiao Zirong is divorced from, she will probably be shocked.

Xiao Zirong looked at her worried look, thought for a while and decided that he should reveal it, after all, he is also someone who has been with him for a long time: "Don't worry about me, there are already people in my room."

It's just that they often live in two places.

Liu Cainiang was obviously a little surprised: "Who is it?"

Xiao Zirong said, "Well, you've known each other for a long time."

He didn't say it directly, but he wanted to pave the way for Liu Cainiang to think for himself, so that the impact might be smaller.

At first, Liu Cainiang wondered if it was Bai Yan, but after thinking about it, it should be impossible. Nothing happened in Taoyuan City back then, so how could they be together now?

But...except for the few of them who have been following him all this time, the whole of Jinling can't be regarded as having known each other for a long time.

Seeing her frowning and guessing, Xiao Zirong didn't say it directly, and gave a very malicious reminder: "He is now in Jiankang."

Well, this tip should be more straightforward, right?

However, Liu Cainiang frowned after thinking for a long time and said, "Is Your Highness lying to me? Is there a lady in Jiankang that you have known for a long time?"

Xiao Zirong winked at her: "Don't restrict gender so rigidly."

Cainiang Liu:? ? ? ?

Looking at Liu Cainiang's shocked expression, he thought he could guess it now, right?

Liu Cainiang said with a difficult face: "Could it be... Ling Fu?"

Xiao Zirong:? ? ?

He also looked at Liu Cainiang in shock: "Why is it Ling Fu? I don't want a beauty like the Regent, I want Ling Fu? What do you think?"

Liu Cainiang was even more shocked, her mind was full of thoughts: His Royal Highness and the Prince Regent got together.

Isn't this news more exciting than Xiao Zirong having an affair with Ling Fu?

Seeing that Liu Cainiang was stunned, Xiao Zirong stretched out his hand and shook in front of her: "I'm back to my senses."

Liu Cainiang replied in a daze, and followed Xiao Zirong without saying anything.

Before Xiao Zirong entered the yard, he smelled a unique smell of fur, mixed with the smell of sheep, which was not very pleasant to be honest.

The steward who was in charge of the yard came up to him and asked cautiously, "Your Highness, do you want some incense?"

Xiao Zirong thought for a moment about the chemical reaction that might be produced by the combination of smell and fragrance, and suddenly his face turned green and he said directly: "No need."

The smell is just unpleasant, but if you use aromatherapy, it will become a biochemical weapon.

He went in with the steward. At this time, the wool had actually been processed for the first time. When the merchants harvested Tuyuhun, the merchants had already asked the local people to process it once. It should be processed twice. However, the wool at this time was still Somewhat dirty.

The steward explained: "There is some oil on the wool, which is not very easy to clean. I washed it again according to the method of Tuyuhun, but it still can't meet His Highness's requirements."

Xiao Zirong's requirements for wool are white, soft and loose, and whiteness can be relaxed, because sheep are not the same as sheep, and not all sheep's wool is white.

But it's loose and soft... Even after two treatments, it still can't be achieved, so the steward was a little puzzled and asked carefully: "Is the method on Tuyuhun wrong?"

He almost said that the Tuyuhun people lied to them.

Xiao Zirong shook his head and said, "Their method is correct, but their usage of wool is different from ours."

Tuyuhun seldom uses wool to make clothes. Most of them are made of felt or blankets. Even if they are made of clothes, they are relatively rough outerwear, and the processing method is naturally not too delicate.

Xiao Zirong looked down at the wool and said, "Now it's not just the oil, but also the grass seeds that haven't been completely removed. Let's try carbonization first."

When Xiao Zirong said this, he suddenly turned his head and said to Ah Yin who was behind him: "Go and call Zhai Ling and the others over."

The processing of wool also involves a series of chemical reactions, and it doesn't hurt to let them know that it might come in handy at some point.

When Zhai Ling came over, he greeted Liu Cainiang with a smile, and Liu Cainiang nodded in a daze.

Zhai Ling asked in surprise, "What's the matter? Is Sister Liu not feeling well?"

Xiao Zirong didn't expect Liu Cainiang to react so strongly, coughed lightly and said: "It's okay, come here, I will tell you the principle of carbonization. The carbonization of wool uses acid and high temperature. The main component of these grass seeds and grass clippings is fiber. Do you still remember the concepts of vegetarian and cellulose?"

Zhai Ling nodded vigorously: "It's written in the book!"

Xiao Zirong vaguely found the feeling of teaching Zhai Ling and the others back then, smiled and said: "At high temperature, cellulose is dehydrated and carbonized by acid, so the impurities after carbonization of grass seeds and grass clippings are very fragile and easily broken. It can be removed from wool, but if the removal process is done manually, it will be very troublesome, so I will give you a homework to find a way to make a device that can quickly remove these impurities and reduce manual operations, can it be done?"

Zhai Ling immediately said: "Don't worry, Your Highness, we will definitely research it as soon as possible."

Xiao Zirong replied: "You guys draw a blueprint before doing it, and show me after you draw it."

This machine is likely to rely on manual operation, so he doesn't intend to give the blueprint directly. Zhai Ling and the others have already mastered the basic knowledge, and it is time to learn how to use it by themselves.

Just when Xiao Zirong was about to continue talking, Liu Cainiang, who was next to her, suddenly reacted, turned her head to look at Xiao Zirong and said anxiously: "Your Highness, Your Highness, you...how can you be with the Regent? This... ...How do you explain to His Majesty?"

The scene was so quiet that you could hear a needle drop.

Xiao Zirong: I treat you as my own and you help me come out in public?
