"Young Master!" Ah Da jumped from the tree, he didn't listen to their chat, but he and Ah Er had to be on guard, and he looked a little nervous at this time.

"Do we have a place to hide?"

"Yes!" Ah Da and Ah Er led the two into the workshop and transferred them to the inner room of the account room. On weekdays, only Uncle Li occasionally comes over to write down the accounts, so there is no one here at this time.

Ah Er opened the inner panel of a cabinet door, and there was still a room inside. It's not big, but there are still tables and chairs.

"Will anything happen to the craftsmen outside?" Xin Kun frowned.

"You two will hide it." Ah Da didn't speak, and closed the partition.

Xin Kun was busy trying to open it, if something happened to Tuzhuang, she would be uneasy for the rest of her life. At this point, she would rather go out. But the partition turned out to be opened and closed from the outside. She can protect herself in Riga and keep people from coming in. But she wanted to get out, and that was impossible. Thinking about it, she really added protection, and a big iron rod was blocked on the steel bolts on both sides. And the steel bolt is welded to the door, and if you want to get out, you can only tear down the wall.

Xin Ye had already sat down and took a bookcase against the wall, and there were still a few books in it. However, none of them are what Xin Ye likes, four books and five classics, few people will like them. Thinking about it, he put it back and picked up the ink ingot and sharpened it.

"Grandpa, do you know this?"

"Well, I asked them to repair it, this looks like adobe on the outside, but there is an iron plate in the middle inside, not too thick, and it is impossible to get in without the sword of the little prince. You see, at the top are blowholes, and no one can suffocate us in them. ”

"But we're going to be locked up and killed! How are we going to get out in case no one comes to save us? ”

"There is also an exit, rest assured, they don't know about this Da, and Lao Li doesn't know either. I asked someone to design it, and I almost forgot to tell you. Xin Ye smiled.

"Grandpa!" Of course, Xin Kun knew that this was what the old man did for himself, and he was a little depressed when he thought about it, how hated he was, so he had to force the old man to get himself an iron house directly.

"It doesn't matter if you're Jian'er's daughter or not, but you're my granddaughter, I won't let anything happen to you." The old man smiled, his ink was polished, and gave her the pen, "Let's tell me what grade steel of yours, in your meanest, steel also has a formula?" ”

"Like bronze, the difference in copper-tin ratio is destined for their texture. I can't say ......," Xin Kun began, writing about some of the characteristics of the grade steel she knew.

Although she doesn't know how to practice steel, they enthusiasts are also very clear about the composition of steel. Of course, she didn't know how to add these ingredients. She just knew that different grades of steel could hit different kinds of tools.

In modern times, there is a materials research institute, and this is what people specialize in. In order to research and manufacture different kinds of materials to meet the ever-changing requirements of that time. And all she can say now is that she wants to give it a try. She has a feeling that if she wants to live, she has to be unique, and uniqueness must be the thing that the rulers care about the most, otherwise, it is still useless.

Xin Ye and Xin Kun quietly studied Xin Kun's ideas in this hut, the old man was much more professional than Xin Kun, he looked at Xin Kun's thoughts, and shook his head, "We can't actually do it, metallurgy is not like your Aunt Li making soup, you can throw whatever you want." When to throw it, how much to throw it, as well as the heat and temperature at that time, are all to be described accurately, so according to your ideas, we can only continue to practice scrap iron. ”

"yes, the temperature is a big problem." Xin Kun nodded, the high temperature of several thousand degrees was not something that a small workshop like them could have now. So not everyone is a god of crossing, at least not himself.

"You can try this." Xin Ye refers to a soft alloy. This metal is relatively soft, so the temperature required is not high, and it is easier to succeed than other materials with high hardness.

"Well, this kind of armor can be made into some soft silk armor, and when fighting, this kind of armor is much more durable than ordinary cowhide armor."

"For the little prince?" Xin Ye frowned, so this was specially tried by Xin Kun, just to make it for Guo Peng to make armor?

"Well, he wants to go to war, and I'll have to give him a full suit." Xin Kun nodded.

"This is not as good as the stainless steel armor in the palace." Xin Ye could imagine what Xin Kun wanted to do, but he wasn't optimistic.

"This is worn inside, I just said, I'll give him a soft silk armor." Xin Kun explained.

Although in fact, the old man didn't understand. He hesitated for a moment, "That, soft armor is also sold in the shop, but it is also woven from steel wire with the thickness of noodles." You use this kind of mild steel, draw it into filament, and spin it into armor, but in fact, you are afraid that the defense is still insufficient. ”

At this time, there is also a legend in the rivers and lakes that there are 'divine weapons', which not only refers to those famous weapons, but also includes those protective gear, as long as it is really the best and can save life, it is the same as the top ten famous swords, and they are all on the list, and no one dares to say that that thing is in their own son.

Xin Kun obviously planned to give Guo Peng one himself, but the old man couldn't say that that thing must be useless. However, he is also a professional, he can imagine what Xin Kun wants to do, this thing, if he can't prevent himself, it will be a failure. So he didn't want his granddaughter to suffer the pain of failure. It was precisely because she had never failed that he was even more uneasy.

"You don't have to be like that kind of chain mail, that one is a bit heavy, and it really wears out, who doesn't know how much he wears on him. What I want to do is that I won't be found when I go into the palace and search my body. At most, it will feel like he's gaining weight, but it won't feel like he's wearing something in it. ”

"It's not just hard." The old man had another headache, that is, to pull the tightrope, and to weave it into cloth and make underwear. This is used to deal with small scenes, even if someone stabs him with a sword, as long as it is stabbed in that clothes, he can run for his life. It was designed to be used for escape.

"yes, it's hard." Xin Kun also sighed, if it wasn't difficult, she wouldn't be annoyed. The kind of noodle-thick soft armor that Xin Ye said looks about the same as European knight armor, but it is also worn outside. What Xin Kun imagined was a bit like Huang Rong's soft hedgehog armor in the Condor Shooting. But the book also said that it was not iron and cloth, and it was a rare treasure in the rivers and lakes. But Jin Dada didn't say what it was made of!

"It's okay, try slowly. Little Wangye, I don't think it's short-lived, you will definitely be able to do it. "What can the old man do, saying that he made a steel foil to make clothes for the little prince, in addition to the lack of toughness, the protection must also be very limited. So the old man made a difficulty. He was thinking positively now, it was because he suddenly thought that if he succeeded, Xin Kun would be able to wear one.
