In the fifth year of Longsheng's reign, December 20th.
Jinling City.
East Palace, an empty palace.
Basically all the paper-making materials Qin Yu needs are ready.
Although it had only been one day, Cheap Dad had already sent people to urge him many times because he was afraid that Qin Yu would not work for him.
The key is that papermaking is a difficult task, but Qin Yu said it so lightly. Although he trusted Qin Yu, he still couldn't help but feel worried in his heart.
The clerk from the household department who came to urge him was sent away.
Qin Yu began to look at the materials Deng Bao had found.
In fact, the materials are very simple, just bark, reeds, broken hemp, etc.
Xiao Nan stood aside, eager to try, "Brother-in-law, where should we start?"
Developing a simple papermaking technique is a great thing that will go down in history and be remembered for eternity. Xiao Nan will not miss it.
Shen Binglan stood aside, her eyebrows slightly raised, watching quietly without saying anything.
Qin Yu had done too many shocking things, so she wasn't surprised.
Qin Yu said lightly: "Actually, making paper is very simple. You need to chew up all the bark, reeds and broken hemp heads first. I will be of great use."
Xiao Nan looked at Qin Yu with a confused expression, "Chew...chew it to pieces..."
Qin Yu smiled and said, "I said it wrong, it was chipped."
Xiao Nan puffed out his chest and said with confidence, "Brother-in-law, leave these tasks to me, so you can rest assured."
In fact, as long as you know the principles of papermaking, this thing is not difficult.
It doesn't matter what raw materials are used for papermaking, because what is needed is the cellulose in bark, reeds, etc.
Cellulose is the main material for papermaking.
But there are lignins connecting cellulose to each other, so to get cellulose, lignin must be removed first.
Xiao Nan was crushing all the raw materials for papermaking.
Qin Yu and Shen Binglan were preparing lime water on the side.
Shen Binglan frowned slightly, with confusion on her face. She felt that Qin Yu was obviously doing it for the first time, but he did it very skillfully and accurately in every step, and he never made mistakes.
Qin Yu didn't pay attention to Shen Binglan's expression and soaked the mashed pieces in lime water.
This step has two functions, one is to decompose and filter impurities, and the other is to remove color from debris.
After filtering and color removal are completed.
Then we come to the most critical step, removing lignin.
The method is also very simple, boil it at high temperature to completely remove the lignin inside.
Then there is pounding to enhance the firmness of the paper, followed by continued washing to remove impurities and enhance the whiteness, and then grooves to make the paper fibers on the surface of the barrel more uniform.
Normally, people use paper troughs.
But Qin Yu's conditions were limited, and he only used wooden barrels, but it didn't hurt. After all, it was just an experiment.
After these steps are completed.
The wooden barrels in front of Qin Yu and the others contained uniform pulp.
Immediately afterwards.
This is the most critical step, turning pulp into paper, which is papermaking.
Later, under the leadership of Qin Yu,
They used papermaking molds to pick up the pulp that had been beaten evenly in the barrel, and then placed the papermaking molds with paper in an area surrounded by several stoves for drying and drying.
Although the paper on the papermaking mold frame is still wet pulp at this time.
But the shape of the paper has already begun to take shape.
Anyone can tell at a glance that as long as it is dried, it will be a complete, white and shiny piece of paper.
Looking at the paper on the papermaking template.
Xiao Nan's eyes were almost pierced, and his face was full of excitement and disbelief, "Brother-in-law, this...is this done?"
He really couldn't believe that paper was made so simply by breaking the bark of trees.
Shen Binglan's beautiful eyes were also flashing with wonder.
She felt that she had been numbed by Qin Yu's anecdotes one after another.
But when Shen Binglan saw with her own eyes that the rotten tree bark and rotten pockmarks turned into white paper in front of her, she was still shocked.
The simplicity of the materials used in Qin Yu's papermaking is astonishing.
The simplicity of Qin Yu's papermaking technology is even more astonishing.
From the perspective of Xiao Nan and Shen Binglan, there is nothing difficult at all, it is just a matter of a few details.
However, they also understand that just these few details are enough to determine the success of this papermaking technology.
Xiao Nan couldn't help but give Qin Yu a thumbs up, "Brother-in-law, you are really strong. You can make paper so easily. Then in the future, our Wei Dynasty will still use crappy bamboo slips? Change them all to
Paper book!”
Although Xiao Nan doesn't like reading, he still has some affirmation of papermaking.
Qin Yu smiled calmly, "Then I don't care. We have been busy for such a long time, so we should give us a small reward, right?"
Xiao Nan smiled and nodded in agreement, "Brother-in-law is right, then let's go to the side hall."
The words fell.
Qin Yu and Xiao Nan raised their feet and walked out of the hall.
Shen Binglan looked at it and felt speechless for a while. She felt that in Qin Yu's heart, it seemed that this unique and irreplaceable papermaking technique was not as important as a song.
She shook her head helplessly and had no choice but to follow.
Shen Binglan is relieved now. Perhaps if it weren't for Qin Yu's character, he wouldn't have achieved such an achievement.
.......
The next day.
Noon.
East Palace, Side Palace.
Since the paper has been dried.
Qin Yu and Xiao Nan once again lived a life of luxury and sensuality.
Compared with working as coolies in the Ministry of Household Affairs, their lives now are really less carefree.
Vocal music was playing in the hall, and the lingering sound lingered around the beams.
A group of beauties swayed their fair and slender waists.
Qin Yu and Xiao Nan were enjoying themselves watching it.
Qin Wenyao and Wei Huang rushed in from outside the palace in a hurry.
All the beauties were frightened and hurriedly stopped and retreated.
Xiao Nan stood up subconsciously, trembling.
Qin Yu was drinking wine, still looking calm and calm.
Qin Wenyao looked at Qin Yu, his eyes darkened, "Yu'er, how is the paper made?"
He was very busy in the household department and couldn't wait to see anything.
But Qin Yu was singing and dancing here, drunk and happy, and was very happy.
However, Qin Wenyao's tone was not too high and his words were not very sharp.
Because he knew that if Qin Yu said he could do it, he would definitely do it. He just couldn't stand Qin Yu's lazy look.
Emperor Wei smiled and said: "Wen Yao, don't worry. If Yu'er said it can be made, then it can be made. I guess he is tired from working and is relaxing here."
Qin Wenyao: "???"
He looked at Emperor Wei with a confused expression.
He and Emperor Wei came together just now. Emperor Wei's face became even more angry and he said he would hang Xiao Nan up and beat him.
Qin Wenyao thought to himself: This... this damn person sold me as soon as he entered the house?
