The mold is made, a small piece of breastplate. Reynolds is preparing to test the relationship between thickness and stress. It does not need to be too large, and can be calculated according to the proportion.

Another furnace came out there, which increased the experimental materials in his hand by more than three or two. He could barely make two pairs of breastplates, of course, it was an extremely shrinking version. The breastplate mold was only the size of an adult's palm.

Dry, smel, remove impurities, cast molds, and use molds to press lightly. This is the characteristic of metal. Unlike iron and fine iron, you cannot use too much force to this kind of metal. The greater the force it gives, the stronger the rebound force. Light pressure is the king.

Without modern experimental equipment, this job is not easy to do. Even with Cui Qing as an assistant, two blacksmiths and more than ten coolies, Renault was sweating profusely.

When the breastplate became cold, I put it on the forging table and called a few Yulin soldiers and sent them a row of sledgehammers, knocking them in turns from childhood to adulthood.

The sound of dinging sounds continued. It was not until a seventh-grade warrior took action that he smashed the breastplate as big as a palm with a large iron hammer.

Not bad, very good. The power of a seventh-grade warrior is not comparable to that of ordinary people. With the large hammer, Renault thinks this can be accomplished.

"Cui Qing, is there any free furnace in the craftsman camp?" Renault asked. This furnace is three or three furnaces a day, and the speed is too slow. The daily output is only more than one pound. When will it take to wait?

"Sir, I'll go and ask someone." He really didn't know about this. After waiting for half an hour, the craftsman replied. The furnace in the small furnace was full and the army was preparing to fight. All the blacksmiths were busy. Because the number of ores was not large, there were several large furnaces empty.

The big furnace is good, 500 kilograms at a time. Anyway, Renault is not ready to make steel. Just make the flying bull cut-off iron out. The charcoal consumed is less than half of the iron smelting.

"You arrange the manpower and refine the ore you brought as soon as possible, don't have iron. As long as this metal is refined, you will send it here after it is refined." Renault instructed. Siwu had been lying on the other side for a while. It seemed that the Ninth Princess had something to look for her.

After walking out of the back garden, Siwu greeted him: "Sir, please."

The people of Da Chu had too many etiquettes. At first, they felt fresh, but after a long time, they were annoying!

"Talk the serious business."

"Yes, sir, the princess has made a sample paper, which is excellent." Siwu was wearing a veil and couldn't see her face. She could hear it from her voice. She was very excited, just like Cui Qing did this morning.

"So fast?" Renault didn't expect that the Ninth Princess was working so hard.

Renault has checked the information. If it is based on the ancient method of papermaking, then wait. It doesn’t take half a month to think about fermenting materials. This method of papermaking is not advisable, and you can’t afford to wait.

Therefore, the papermaking technique he summarized borrowed many modern papermaking methods. He first simply fermented, chopped, steamed, crushed, and finally fermented and stirred in the pool.

In fact, this set has only one purpose, which is to decompose the fibers in the material and finally become floc. What is paper? These floc fibers of plants are gathered together through curtains and remove moisture and become paper.

During this process, Renault also added original additives that can be found such as lime to speed up the process. Even so, according to Renault's calculations, it will take at least three days, and it will be completed in just two days and two nights?

"Mr. Come, the Ninth Princess hasn't slept these two days." Siwu sued a small complaint. In Dingjun City, in the southwest Dingjun City, no one dared to say that the princess is not, and even the general is not good. After Zhu Fu's death, the general and the princess were only known as the monarch and the minister, and were no longer relatives.

When Siwu thought of the princess' marriage, he felt sad. The four of them were one with the princess. When the princess married, they were concubines. If the princess did not marry, they would also keep their lives together.

"Yihe, you haven't slept for two days? How could this happen? Go to bed immediately. No matter what, I'll talk about it when you wake up. Si Ji and Siwu, don't stand stupidly and help the princess to rest. I want to hear my praise or scold people, and wait until I've finished sleeping." Seeing the Ninth Princess, Renault didn't mention papermaking, and he scolded her and ordered the female official to send her back to rest.

After the princess and servants walked away, they turned around and looked at the princess villa. They were all workshops. The flat ground was dug out a material pool, which was full of material liquid. A group of coolies were at a loss and did not dare to look up at Renault.

They knew that they were working for the princess these two days, and that was the ninth princess of the empire. They didn’t know who they were here, so they scolded the princess. It was so scary.

"The little one is a temporary...the little one is a small one..."

"What's your name?" Renault asked calmly.

"Little Lu Youde."

"Are you a showman?" Renault continued to ask. He could see that Lu Youde was timid and he would not dare to speak on his own.

"The little one...the little one is not."

Well, this is an uneducated person. Renault does not discriminate against illiteracy. In Dachu, there are not many people who recognize words. I have come into contact with either generals or gang merchants, and even tiger teeth can recognize a lot of words.

After he came into contact with the soldiers, he found that there were no few people who could read the literacy of the soldiers below the team. Thinking about the big seal script, Renault was so worried that it was much more difficult than simplified Chinese.

He has been studying for almost a month, and now there are less than 200 large seal scripts that can be recognized at a glance. Renault has begun to wonder if he is a college student.

"Okay, don't be afraid, tell me what you did before?" Renault asked softly. He was a noble man, and it's okay to scold the princess, and it's too much to scare the common people.

"Small, it turns out to be a carpenter in the craftsman." Lu Youde replied in a low voice.

Renault almost laughed out loud. The princess’s way of employing people is unfathomable. She actually uses a carpenter as the manager of papermaking?

This was his misunderstanding. A person as smart as the Ninth Princess naturally would not choose such a manager. She didn't need to manage the business at all. The coolies here are all carpenters in the craftsman camp, and Lu Youde could command them easily. The real manager is the female officials under her. These carpenters who don't even know each other are useless.

"Okay, I heard that the paper was made, so I'll take it to me."

"yes."

After a while, dozens of papers were delivered to him, which was quite regular, but the thickness difference was too big. Renault knew that this was a paper sieve worker, and he would be fine after practicing for a few days.

But this paper...

Not suitable for use!

Renault's papermaking technology has added a lot of natural additive materials, which are much better than yellow paper. Not only are they white and flat, but they can't see many impurities. They shake gently and have a good toughness. At least they are fine with writing.

But the paper is too thick and too hard, and this is not what he wants.

After looking at the material pool, there is still a possibility of remediation. The Ninth Princess has completed the preliminary work very well.

"Lu Youde, go and get quicklime and sheep oil."

Renault had no choice. There were too few details in the fantasy novel. He checked it several times, but he couldn't find out the papermaking process. He all mentioned it all.

Needless to say, lime is used as a natural softener. It is said that the main ingredient in pulp softener is oil. As for the details, I can't find it, so I can only use it and try it.

Adding natural additives, the next step is to stir, stirring constantly, making several carpenters sweat all over their bodies. Only then did Renault feel that it was almost done.

"Come on, try sifting one."

Looking at the two coolies holding bamboo sieves and clumsy sieves, Renault had an impulse and wanted to kick them away and get started by himself.

Fortunately, he could still control himself. Renault knew in his heart that he was also an amateur. He occasionally saw ancient sifting paper on TV, but he had never tried it. He was probably not much better than these two coolies when he started.

After sifting back and forth a piece of paper dozens of times, Renault couldn't bear it: "Don't sift it back and forth, put the sieve in the pulp, just go back and forth once."

Coolie quickly stopped and carried the sieve to the side. A few more people came up and they actually wanted to use their hands to get the paper. It's crazy. The paper on the sieve has not yet been formed and it breaks as soon as it touches. In addition, his pulp formula is extremely unreliable and cannot be touched.

"Stop, get the flat wooden boards." Renault had to give orders in person, feeling tired.

Wooden boards are easy to deal with. Lu Youde is just a carpenter. After a while, he will carry a few wooden boards.

"It's too big, it's the same size as the sieve."

I took it back and changed it. I couldn't think the tools here were good. With Lu Youde, a carpenter, waiting for a quarter of an hour before I carried a suitable wooden board back.

"Press the board against the sieve and turn it upside down."

With Renault's guidance...

The paper fell off by itself. Lu Youde was working hard to make the wooden board back and forth, and the paper on the sieve was almost done.

I took this new piece of paper and rubbed it with my fingers. It was too thick and felt much softer than before, but my toughness became worse. Fortunately, I wouldn't break it with just a poke.

"Continue, prepare more wooden boards." Renault continued his papermaking career, and thin paper was finally made. Only when it was thin could it realize the benefits of this paper. It was much softer than the previous paper. Although it was far from crust paper, at least it could be used.

"Take a knife and cut the paper." Lu Youde was commanded and turned around, looking at the small paper, a little confused. This paper is not big, so why should I cut it?

Anyway, I just followed the instructions. When the knife was brought over, Renault discovered that Da Chu did not have a paper knife, at least not here. Lu Youde brought a thick-backed guillotine, which was originally used to chop grass. He polished it a few times, and there were also several holding horizontal knives and kitchen knives...

You know that Lu Youde knew that he was not educated and heard that he wanted a knife, so he brought all the knife he could think of.

The guillotine is the flattest and should be the most suitable, but it is too blunt. The horizontal knife is curved and the kitchen knife is too short...

Well, there is no one suitable one, so I can only use it first. After taking a piece of paper, fold it four times in a row, cutting the paper with a horizontal knife, cutting the paper as wide as toilet paper, and feeling infinite joy.
