The mold was made, a small piece of cuirass, and what Renault was ready to test was the relationship between thickness and stress, which did not need to be too large, and could be calculated proportionally.

Another furnace came out over there, which increased the experimental materials in his hand by more than three taels, and he could barely make two pairs of cuirass, of course, it was an extremely shrunken version, and the mold of the cuirass was only the size of an adult's palm.

Drying, smelting, removing impurities, casting molds, and light pressure with molds, this is the characteristics of metal, and iron, fine iron is different, this metal you can't use too hard, the greater the force to give it, the stronger the rebound force, light pressure is the king.

Without modern experimental equipment, this work is not easy, even with Cui Qing's assistant, plus two blacksmiths, and more than ten coolies, Renault is also sweating hot.

When the cuirass was cold, he put it on the forging platform, called a few Yulin soldiers, and gave them a row of sledgehammers, knocking them in turns from small to large.

The sound of clanging was endless, and it was not until a seventh-rank martial artist made a move that he smashed the palm-sized breastplate with a large hammer.

Not bad, very good, the strength of the seven-rank martial artist is not comparable to ordinary people, plus the large iron hammer, Renault feels that this can be done.

"Cui Qing, is there any spare furnace in the craftsman's camp?" Renault asked, this furnace is three taels, three furnaces a day, the speed is too slow, the output of a day is only more than one catty, when will this be?

"Sir, I'm going to get someone to ask. He really didn't know about this, and after waiting for half an hour, the craftsman's battalion replied that the small furnaces were full, and the army was ready for battle, and all the blacksmiths were busy, because the amount of ore was not much, but there were several large furnaces empty.

The furnace is good, five hundred catties at a time, anyway, Renault is not ready to make steel, as long as the flying cow is cut off, the charcoal consumed is not even half of the iron smelting.

"You arrange for people to bring in the ore and smelt it out as soon as possible, no iron, as long as this metal, after it is refined, it will be sent here. Renault instructed, Si Wu has been probing his brain for a while, and it seems that the ninth princess has something to find herself.

Walking out of the back garden, Si Wu greeted him: "Please sir." ”

There are too many etiquettes of the Great Chu people, and they still feel fresh at first, but after a long time, they are annoying!

"Get down to business. ”

"Yes, sir, the princess has already made a sample paper there, and it is excellent. Si Wu was also wearing a veil, and he couldn't see her face, and he could hear it in her voice, she was very excited, just like Cui Qing did this morning.

"So fast?" Renault didn't expect that the Ninth Princess would also fight so hard.

Renault checked the information, if it is completely according to the ancient paper-making method, then wait, just the material, you don't have to think about it for half a month. This method of making paper is not advisable, and the ass can't afford to wait.

Therefore, the papermaking technology he summed up borrowed from many modern papermaking methods. First, simply soak it, chop it, steam it, crush it, and finally put it into the pool and stir it while soaking.

In fact, this set has only one purpose, to decompose the fibers in the material, and finally become flocculent. What is paper? It is these plant flocculent fibers, which are gathered together through the curtain, and after the water is removed, it is paper.

In this process, Renault also added lime and other original additives that could be found to speed up the process, even so, according to Renault's calculations, it would take at least three days, and it would only be completed in two days and two nights?

"Mr. Hui, the ninth princess hasn't slept for the past two days. Si Wu complained a little, in the southwest Dingjun City, except for Mr., I am afraid that no one dares to say that the princess is not, not even the general, after Zhu Fu's death, the general and the princess only have the name of the monarch and the minister, and they are no longer relatives.

Thinking of the princess's marriage, Si Wu's heart rose to sadness, the four of them and the princess are one, the princess marries, they are concubines, the princess does not marry, they also have to follow for a lifetime.

"Yihe, you haven't slept for two days? How can this be done, go to sleep immediately, no matter what, wait until you wake up, Si Ji, Si Wu, don't stand stupidly, help the princess to rest." If you want to hear me praise or scold, wait until you have enough sleep. Seeing the ninth princess, Renault didn't mention the paper-making matter, he opened his mouth and counted her down, and ordered the female official to send her back to rest.

When the five princess masters and servants walked away, they turned around and looked at this princess courtyard, which had become a workshop, and the flat ground had dug out a material pool, which was still full of material liquid, and a group of coolies were at a loss, and they didn't dare to look up at Renault.

They knew that they had been working for the princess for the past two days, and that was the ninth princess of the empire, and they didn't know who was coming, so they opened their mouths and scolded the princess, which was too scary.

"Little ...... The small ones are temporary...... Charge...... Small ......"

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

"Little Lu Youde. ”

"Are you Xiushi?" Renault continued to ask, he could see that this Lu Youde was timid, and if he didn't ask, he was afraid that he wouldn't dare to take the initiative to speak.

"Small...... The small ones are not. ”

Well, this is an uneducated, Renault does not discriminate against illiterate, and in Dachu, there are not many people who can read. In the past, I came into contact with either generals or gang merchants, and even Huya could recognize a lot of words.

When he came into contact with the soldiers, he found that there were not many literate soldiers below the line. Thinking about the big seal again, Renault is panicked, which is much more difficult than simplified characters.

He has been studying for almost a month, and now there are less than two hundred big seals that he can recognize at a glance. Renault began to wonder if he was a fake college student.

"Okay, don't be afraid, tell me what you used to do?" Renault asked softly, he was a nobleman, it was okay to scold the princess, and it would be more embarrassing to scare the little people.

"The small one turned out to be a carpenter from the craftsman's house. Lu Youde replied in a low voice.

Renaud almost laughed out loud, the princess's way of employing people is unfathomable, and a carpenter is used as a steward for papermaking?

This is his misunderstanding, the ninth princess is such a smart person, naturally she will not choose such a manager, she doesn't need to be in charge at all, the coolies here are all carpenters in the artisan camp, and Lu Youde is easy to command. The real stewards are the female officials under her, and these carpenters who don't even know a word are useless.

"Well, I heard that paper is made, show it to me. ”

"Yes. ”

After a while, dozens of pieces of paper were delivered to the front, which was neat, but the difference in thickness was too big. Renault knew that this was a paper sieve or a manual student, and it would be good to wait for a few days of practice.

But this paper ......

It doesn't work!

Renault's papermaking technology adds a lot of natural added materials, much better than yellow paper, not only white, flat, but also not much impurities, gently shaken, toughness is also okay, at least for writing is no problem.

But the paper was too thick and too hard, and it wasn't what he wanted.

Looking at the material pool, there is still the possibility of remedy, and the ninth princess has completed the preliminary work very well.

"Lu Youde, go get quicklime and mutton fat. ”

Renault can't help it, there are too few details in the fantasy novel, he checked it several times, and he didn't find out the process of papermaking, all of which were brushed aside.

Needless to say, mutton fat 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, I can only use it, touch the stones to cross the river, try to come.

Adding natural additives, the next thing is stirring, stirring, and making a few carpenters tired and sweaty, and Renault feels almost the same.

"Come on, sift one. ”

Looking at the two coolies, holding a bamboo sieve and clumsy sieve paper, Renault had an impulse to kick them away and do it himself.

Fortunately, he can still restrain himself, Renaud understands in his heart, he is also a layman, occasionally I have seen the ancient method of sieving paper on TV, I have never tried it, and I am afraid that it is not much better than these two coolies.

A piece of paper was sifted back and forth dozens of times, and Renault really couldn't bear it: "Don't sieve back and forth, put the sieve in the pulp, just go back and forth once." ”

The coolie hurriedly stopped, carried the sieve to the side, and a few more came up, and actually wanted to use his hands to get the paper, crazy, now the paper on the sieve has not yet been formed, it will break when touched, and his pulp formula is extremely unreliable, and he can't touch it.

"Stop, get the planks flat. "Renault had to give orders in person, and he was tired.

The planks are easy to handle, Lu Youde is a carpenter, and after a while, he will bring a few planks.

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

Take it back and change it, the tools here can't be any better, with Lu Youde, a carpenter, there, and he waited for a quarter of an hour before bringing back a suitable plank.

"The plank is pressed against the sieve and it is turned upside down. ”

With Renault's guidance......

The paper fell off by itself, and Lu Youde tossed the wooden board back and forth, and the paper on the sieve was almost dry.

I took this new piece of paper and rubbed it with my fingers, it was too thick, it felt much softer than before, but the toughness became worse, but fortunately it would not break when I poked it.

"Go ahead and prepare more planks. Renault continued his paper-making business, and a piece of thin paper was finally made, and only when it was thin could the benefits of this paper be realized, it was much softer than the previous paper, although it was far from animal skin paper, at least it could be used.

"Take a knife and cut paper. Lu Youde was turned around by the command, looking at the small paper and a little confused, this paper is not big, what else is cutting?

Anyway, just listen to the instructions, and when the knife is brought over, Renault found out that Da Chu does not have a paper cutter, at least not here. Lu Youde brought a thick-backed guillotine, which was originally supposed to be used for cauldium, and he polished it casually a few times, and a few of them held horizontal knives and kitchen knives......

Don't say it, Lu Youde knew that he was uneducated, and when he heard that he wanted a knife, he brought all the knives he could think of.

The guillotine is the flattest, it 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 suitable one, so you can only use it first. I took a piece of paper, folded it four times in a row, cut the paper with a horizontal knife, and cut the paper into a width as wide as hand paper, and my heart was full of joy.

Without Renault's command, Lu Youde did the same, let the coolies under him move, one person with a horizontal knife, and began to cut paper.
