"I have read the Three Kingdoms cursoryly, and some of the stories in this picture book are based on this book, but they are not the same." His Majesty Li Er said: "Qi Lin must have been inspired by this book, but it has been changed to be easy to read and understand, and it is full of fun, and it has taken a lot of thought!" ”

Xu Hui said: "Your Majesty, is this considered a serious business?" Today, he was promoted to an official position, isn't it because of this painting book? ”

His Majesty Li Er laughed, touched Xu Hui's smooth little hand, and said: "Qi Lin has meritorious advice today, and if he takes a multi-pronged approach, I will promote him to a third-level reward." Well, this kid is still playing tricks with me, and he almost deceived two more ranks. ”

Xu Hui didn't know why, and looked at Li Er with bright eyes, a little confused and confused, but it was even more innocent and cute.

Looking at the lovely appearance of the concubine, the faint fragrance of osmanthus wafted into the nose, and His Majesty Li Er laughed evilly twice.

But because the little son was still in the palace, he had no choice but to suppress the evil fire, hold the concubine in his arms, gently pinch the soft flesh of her waist and hips, and paste it on her face.

……………..

Although it was a holiday, Xu Qilin didn't sleep lazy, just got up later than when he went to work.

The thunderous morning exercise has long been a part of Xu Qilin's life. Since he competed with Xue Zonggui, he has practiced harder.

Although he has Brother Xiaolong's upper body, Xu Qilin's strength and speed are limited by his own physique. Winning is winning, but it makes him very regretful, and he is quite ashamed to damage the prestige of Brother Xiaolong.

Moreover, even if Xu Qilin doesn't want to stand up with martial arts, being strong and strong in this era of lack of medical treatment is the only way to live a long-term life.

When it comes to exercise, Xu Qilin's equipment and methods can be said to be the most scientific in this era, and of course they will not just throw stones and locks like the ancients.

What squats, jump rope, push-ups...... Xu Qilin still knows a lot about fighting, or what strong muscles are needed in martial arts.

After finishing the morning exercise, washing up, and having breakfast, Xu Qilin left the house and went to the papermaking experimental field outside the city.

When I entered the experimental field, I saw a row of huge water tanks, which were called urns in ancient times. That's right, this is the reaction vessel that Xu Qilin wants to make caustic soda.

"This urn is so big!" Xu Qilin circled around the water tank, and said in his heart: Sima Gang's shoes smashed this water tank, and it is really no problem for children to swim in it.

The official of the Ministry of Industry who was sent to assist was named Zhang Cheng, who was only eight grades, very young, but his attitude was very respectful, and he seemed to have a studious spirit.

For example, Zhang Cheng carried pen and paper and ink in a porcelain vase, Xu Qilin's instructions, and the experimental steps were all written down one by one, and he knew how to ask if he didn't understand.

There is such a person next to him, Xu Qilin has a sense of vanity when the leaders of later generations inspect it, and someone next to him holds a small notebook to record.

Hmmm, huh! Xu Qilin straightened his chest and walked to the side of the pile of debris. Grass, hemp, bamboo, wood, reeds and other materials have been chopped and milled, and processed finely.

Zhang Cheng explained: "In order to make the paper with similar specifications, the lower officials proportionally proportioned the materials, all of which were one. ”

Xu Qilin nodded and said approvingly: "Very good, Brother Zhang is attentive." ”

As he spoke, he pretended to pick up the scraps, tested the fineness, and sniffed them under his nose, wanting to put them in his mouth and taste them—well, now the appearance of an expert is enough.

Taking out a piece of paper from his sleeve, Xu Qilin handed it to Zhang Cheng and said, "According to this ratio and steps, let's start making caustic soda!" ”

Zhang Cheng took the paper and read it. The above is written in more detail, as long as you are literate, you have never done it before, and it is very simple to follow it.

In response, Zhang Cheng beckoned the craftsmen to add water and carry out a chemical reaction in the vat.

Xu Qilin hurriedly reminded loudly: "Don't move too much, protect your face and hands, be careful not to splash the reaction liquid, especially your eyes!" ”

The corrosiveness of caustic soda is not comparable to that of soda ash and quicklime, and these craftsmen must not know it when they first come into contact with it. This is going to have a production safety accident, don't say anything that you can't afford to bear, and Xu Qilin can't bear to hurt people.

Zhang Cheng also repeated loudly, reminding the craftsmen to be careful with their work.

Soda ash and quicklime react in water to form a caustic soda solution, and the underlying precipitation is calcium carbonate.

Adding a large amount of calcium carbonate to papermaking can ensure the strength and whiteness of the paper, and can also adjust the ink absorption, which has better hiding power and optical properties.

Maybe you can skip the process of sulfur bleaching? Xu Qilin sat in the shade and pondered the process of papermaking, thinking about how to reduce costs and improve production efficiency.

At this time, Zhang Cheng walked over, took a pen and paper, and humbly asked Xu Qilin for advice.

Xu Qilin didn't care whether he could understand it or not, and after talking about it roughly, he changed the topic and asked Zhang Cheng to find an engraving engraver and a carpenter, and if there were any unused or carved engravings in the warehouse of the Ministry of Industry, he would also bring them together.

Zhang Cheng hurriedly asked his subordinates to do it, and he didn't drag his feet at all.

In fact, Zhang Cheng also understands that if papermaking is successful, it will be a great achievement. This is a matter personally explained by His Majesty, and it is done, as long as Xu Qilin helps him say a few good words, he will be promoted.

What Xu Qilin wanted was to sawn the ready-made engraving into single words, and then trim and polish them to unify the size and height of the movable type mold.

As for the missing words, it should be the quickest and easiest way to separate the engraving plates and make up a pair of wooden movable type molds.

In Xu Qilin's mind, the engraving can be preserved for a long time, and the wooden type of the same material should also be possible.

Moreover, as long as the government is involved, it is not difficult to make a lead mold and establish a royal printing office.

The efficiency of the Ministry of Industry is still okay, which is also related to the importance of His Majesty Li Er. The lettering craftsmen were quickly summoned and began to work according to Xu Qilin's explanation.

The carpenters made the rotary typesetting frame according to the pattern drawn by Xu Qilin, which is two large wooden wheels, which are divided into several grids, and the wooden movable characters are arranged in the grid according to the rhyme. When typesetting, people sit between two wheels, turn the roulette wheel to the word on the person, turn the wheel to take the word, save time and effort.

Zhang Cheng didn't quite understand what he was doing, anyway, just listen to Xu Qilin's command, success is gratifying, but failure is not his responsibility.

I had a simple working meal at noon, and in the afternoon, Xu Qilin instructed the craftsmen to steam and cook the pulp, and the next steps were washing, screening, beating, whitening, scooping paper, squeezing drying, and baking paper.

Obviously, this paper can't be made today. But Xu Qilin is also familiar with the processes and tools of ancient handmade papermaking, and has ideas for improvement.

For example, tanning, which is the ancient bleaching method, usually requires direct sunlight, which is the professional so-called photolysis method, and it takes two or three months to make the pulp white.
