In the past, Wang Xu had never seen the method of making rice paper, and if he wanted to improve it, he had to figure out how the rice paper was made.

Wang Xu has a hunch that the manufacturing method of rice paper must be infinitely close to modern papermaking, because the quality of rice paper is not much more than that of modern paper, just like toilet paper, but the erosion of moisture is too heavy.

I believe that after improvement, it will be improved, and the main thing is the cost, the cost must be reduced, only in that way, can it be sold on a large scale, so that the West Capital can be profitable.

A few days later.

Wang Xu renamed the paper mill in the western capital to a paper mill, and expanded the scale several times, of course, this also costs money, but it made Wen Qing hurt hard for a while, but when he thought that it was possible to make the kind of paper that Wang Xu said, Wen Qing endured it.

After understanding, Wang Xu found a problem, the papermaking technology of this era is actually similar to the modern one, but the materials are different, and the degree of refinement is not enough, the most important thing is that the paper is missing the two most important things.

The first is an auxiliary material called glue; It is also an additive, which can make the paper smooth and delicate, and the filler can also improve the smoothness and opacity of the paper, and make the paper water resistant. This technology, rice paper can not sit on, and it is also the main difference between modern paper and rice paper in this era.

The second is also an auxiliary material, called pigment, which can increase the whiteness of paper; Dyes can color paper; Other chemical additives can change the properties of the paper to provide some special purpose for the paper.

For example, after the white fuel is filled into the paper, the white paper is unusually white, which is indeed much better than the yellowed rice paper.

........

There are many differences, Wang Xu wrote them all down and kept them for future revisions.

this day.

In the paper mill, Wang Xu brought more than a dozen Wenyuan Pavilion walkers, all of whom had been trained by Wang Xu. He knows the steps of papermaking well, and can effectively guide the work of craftsmen.

However, while they were reused by Wang Xu, they also lost their freedom from then on. I won't be able to get half a step out of here again.

A few days ago, the steel mill was also taken by Wang Xu to walk in more than a dozen Wenyuan Pavilions, and on the second day, Wang Xu asked Zhang Meng to bring hundreds of forest troops and dozens of brocade guards to station. The water surrounding the steelmaking plant is impassable, and all the personnel in the steelmaking plant cannot leave the factory.

Wang Xu did this, but it was also a helpless move, in order to prevent this technology from leaking, he could only grieve the craftsmen and Wenyuan Pavilion to walk. However, in order to make up for everyone, Wang Xu rewarded their family with a large amount of property.

The Science and Technology Institute, the steel mill, and the paper mill are now the three forbidden places in the Western Capital, and only Wang Xu is specially approved by the Military Aircraft Department. to enter, otherwise, it is considered an assassin at the disposal of the assassin.

Coming to the paper mill, Wang Xu personally instructed all the craftsmen to make paper, the process was extremely difficult, and even Wang Xu himself could not do some links, and everyone had to study and decide.

Fortunately, there was no major trouble, there was Wang Xu's modern concept, and after a few days of research, this huge project was completed.

"You're just going to stay here. Assist the craftsmen in making paper, if you need anything, you can tell Yu Linjun and let them do it. Wang Xu was leaving. Said to a dozen Wenyuan Pavilion walkers.

Wenyuan Pavilion is a person who has been studying hard for more than ten years, how can they not know what Wang Xu means, after everyone heard this, they immediately expressed their position.

"King Wen, I will never step out of this place in the future, and I will not leak the papermaking technique."

Wang Xu smiled slightly. Turn and leave.

..............

The steelmaking mill has now been completely set up, and the paper mill is also making progress, Wang Xu went to check it every once in a while, and if the craftsmen did something wrong, he could correct it in time.

It's been a month since the first day of the steelmaking program began, and it's mid-July.

Early this morning, Wang Xu washed up and prepared to implement his third-step money-making plan.

However, just as Wang Xu was about to leave the Chengqian Palace, Jia Hui sent soldiers to the Chengqian Palace to stop Wang Xu, saying that there was something important to report.

Wang Xu wondered in his heart, but he was still waiting for Jia Hui in the study.

It was close to noon before Jia Hui came to the Chengqian Palace.

Entering Wang Xu's study, Jia Hui smiled and bowed his hand: "Jia Hui greets the lord." ”

Wang Xu waved his hand to signal Jia Hui to sit down, and said, "Lord Jia, seeing that you are happy, have you encountered anything good?" ”

Jia Hui had a thick smile on his face, very happy, and the wrinkles at the corners of his eyes stretched out like chrysanthemums blooming, dazzling in an instant. He smiled and said, "My lord, great joy, great joy! ”

Wang Xu was full of doubts and asked, "Where does the joy come from?" ”

"Lord, please look!"

While speaking, Jia Hui unloaded a war knife from his waist and respectfully handed the war knife to Wang Xu.

Seeing Jia Hui take off the war knife, Wang Xu realized that Jia Hui was wearing a war knife around his waist. In the past, Jia Hui wore a long sword on his waist, but today he suddenly changed it to a war knife, if Jia Hui hadn't taken the initiative to take off the war knife and handed it to Wang Xu, he wouldn't have noticed that Jia Hui was wearing a war knife around his waist.

"Sonorous!"

Wang Xu suddenly pulled the war knife out of the scabbard.

"Buzz!"

The sword came out of its sheath, and there was a crisp buzzing sound, and the light shone on the blade, flashing a cold light.

"Good knives! Good knives! ”

Wang Xu looked at the war knife in his hand and praised again and again. The sword was six feet long, the handle was two feet long, and the handle was wrapped with coarse cloth; The blade is four feet long and streamlined; The weight is about 30 pounds, which is just right. Wang Xu stretched out his hand and gently rubbed it on the blade, his skin was in contact with the blade, it was cold and slippery, and he felt a coolness transmitted from the knife.

Walking to the desk with a knife, Wang Xu raised the knife and shouted: "Drink!" ”

With a loud shout, the sword slashed down.

"Click!"

The war knife slashed at the corner of the desk, and a cold knife light flashed, and a corner of the table was chopped off. Wang Xu buried his head and looked at it, only to see that the place where the sword had been cut was neat and smooth, without any uneven places, and the vertical section was like a smooth mirror, smooth. At the same time, the blade of the sword is still as bright as new, and the blade has not been damaged, and it is extremely sharp.

"Okay, if the Western Capital Army is all equipped with such swords, it will be like a tiger with wings."

Wang Xu praised again and again, looked down at the sharp war knife in his hand, and said: "Master Jia, let's go, go to the North School Field, find a few ordinary war knives to try, and see how much difference this knife is from ordinary war knives." ”

Both of them were very excited, and walked towards the school in a hurry.

"Lord Jia, do you guess how many ordinary war knives this kind of steel knife can break if it is continuously chopped?"

Jia Hui thought as he walked, and finally tried to say: "If you cut an ordinary war knife and ensure that this knife is not damaged, you should be able to chop ten handles in a row." (To be continued.) )
