When I returned to the Lin Mansion, it was getting late. Lin Yingyue got out of the carriage, still did not take Shi Yuan, but walked towards his other courtyard with Li Maomao...... It was Li Maomao's little girl who stuck out her tongue at Shi Yuan embarrassedly.

Shi Yuan looked at Lin Yingyue's figure for a long time, and only after a long time did he conclude and say: This chick is really in good shape! Then he returned to his courtyard, but he didn't see Xiao Lei's figure today, and after wandering around the courtyard for a while, Shi Yuan, who had nothing to do, returned to his room.

There were still pastries on the table that Lin Yingyue asked Qingshuang to send in the morning, Shi Yuan smiled slightly, put away the pastries, and sat down at the desk...... He wanted to practice calligraphy, which was the only thing he could find at night to relieve boredom since he crossed over. But seeing the paper and ink on the desk, Shi Yuan couldn't help but think of the papermaking technology he saw in the paper mill today, and Shi Yuan also had a general understanding of the ancient papermaking process today...... Improve papermaking! This thought suddenly burst out of Shi Yuan's heart, after all, Old Man Lin had a life-saving grace for himself, and he should do something to repay him!

Improved papermaking ...... Shi Yuan remembered that it was done by a man named Cai Lun. And it seems that this man is a eunuch...... But this world is different from the world he is in, according to Shi Yuan's estimate, the world where he is currently located should be more advanced and has undergone improvements. However, compared with the production scale and method of modern assembly lines, it is still extremely backward. Moreover, the raw materials used in papermaking are mainly wood, and the paper has never been recycled, and the cost is also very high. Therefore, although there is a lot of demand for writing paper, it is not circulated among the people. Speaking of which, I even have to use rice paper to go to the toilet, which is really a bit of a tyrannical thing!

It has been some time since Shi Yuan crossed over, but he has not accepted this matter. It wasn't until yesterday that Mr. Wenyan, who was teaching, made him angry, and he began to accept his situation...... Since there's no going back, let's do something! Shi Yuan has always been a good student with excellent character and learning, until he finished graduate school, went to society, and became a hard-working office worker, that he found that the knowledge he learned seemed to be useless...... If you learn mathematics, physics and chemistry well, you are not afraid to go all over the world, and he has not used any of those formulas and equations...... But now Shi Yuan is secretly glad that he is "studying hard", and it is really not wrong...... Improving papermaking techniques, for him, this is not too difficult, but Shi Yuan still has to sort it out, after all, this is in ancient times, and it still has to be combined with the current existing papermaking process.

Shi Yuan turned out the "pencil" made of toner when he was bored, this "pencil" was still when Shi Yuan first came to the Lin Mansion, and he thought it was really troublesome to write with a brush, so he got some toner, and some gum and water, dried it and made it into a carbon rod, stuffed it in bamboo, and made a simple pencil. Later, I practiced calligraphy by myself, and I forgot about it for a while...... Now if you want to write these things yourself, using a pencil is just the right fit! Shi Yuan pondered for a while, then smeared it on the paper, and the papermaking process, materials, processing, bleaching, etc., slowly became clear on the paper!

In this era, paper was also used for a wide range of purposes, but most people used crude hemp paper to write or wrap things. The paper made by the Lin family is a "high-grade product": there are strong ink absorption and weak ink absorption, the strong ink absorption is made of wood fiber, and the weak ink absorption is made of bamboo fiber, the use is also different, but they are all for writing, the paper made by the Lin family is better made of bamboo, and it is also the most distinctive place of the Lin family's paper. In addition, there is also refined rice paper, made of rice stalks and mulberry skin, which has the strongest ink absorption and the best texture, and is used by some literati and ink writers to write calligraphy and paintings. The Lin family's paper and the Lin family's ink inkstone can complement each other, which is why the Lin family not only sells paper, but also does the business of the four treasures of the study! To put it simply, the Lin family is in the stationery business, but there are not many people who can read and write at this time, so the four treasures of the study are expensive! But in any case, at this time, the paper processing is refined, it is only done by feeling and experience, there is no specific system, there is no specific formula, and these people do not know what physical changes and chemical reactions. Therefore, the paper made is a little yellowed and rough, Shi Yuan wants to list these things and add them to the paper mill to make the paper delicate, smooth and more exquisite!

Unconsciously, it was already dark, but Shi Yuan didn't care, lit the oil lamp, and still wrote and wrote drawings and formulas on paper. From time to time, I also used the "pencil" in my hand to pick off the wick, so that the writing became much clearer.

"What are you doing?"

The sudden sound startled Shi Yuan, and the charcoal in his hand was folded into two ends with a force. Shi Yuan was annoyed for a while, so he looked up, only to see Lin Yingyue standing in front of him.

"Miss Lin...... You're going to scare people to death! By the way, why are you in my room? Shi Yuan calmed down and asked with a slight unhappiness.

"Why are you so fierce! I just saw that the lights were on in your room, and I knocked on your door, but no one answered, so I came in...... What are you doing? Lin Yingyue looked at the paper on Shi Yuan's table and asked puzzled.

Shi Yuan smiled when he heard the sound and said, "I'll tell you in a few days, it's a great thing anyway!" ”

Lin Yingyue saw that Shi Yuanshen was mysterious and secretive, so she didn't ask much. I didn't see Shi Yuan's face clearly when I came in just now, but this time, Lin Yingyue burst out laughing. It turned out that Shi Yuan had been writing with his head down, and the oil lamp was too close to him, so he was smoked into panda eyes......

Shi Yuan listened to Lin Yingyue's guidance, wiped the circles on his face, and then asked, "Do you have anything to do with me?" ”

When Lin Yingyue heard this, she snorted coldly and said, "Let me ask you, did you give the pastry I gave you in the morning to Steward Wang?" ”

When Shi Yuan heard Lin Yingyue's words, he was stunned for a moment, and said, "Yes, what's wrong!"

"You ......" Lin Yingyue was stunned by Shi Yuan's natural words, and didn't know what to say.

"Isn't it just pastry! In the morning, Steward Wang came to me, and I divided some of them, as the saying goes, it is better to be happy alone than to be happy...... It's just pastry, why are you so stingy, Miss Lin? Shi Yuan didn't know that Lin Yingyue's mother was a Yangzhou woman, and her favorite thing to eat before her death was this Yangzhou flower cake, Lin Yingyue would bring some back every time she went to Yangzhou, which was regarded as a treasure! Usually only Old Man Lin can eat it, and Lin Yingyue has never given it to anyone. This morning, I met Shi Yuan, who was looking for a kitchen, and somehow got it for a while, so I thought of this flower cake, and gave it to Shi Yuan......

"What is better to be alone than to be happy with all...... I won't pursue Steward Wang's share, if I let me know that you give someone else the pastries I gave you, I will ......" Lin Yingyue was annoyed in her heart, but she was also made by Shi Yuan's words and couldn't smile bitterly, and there was nothing she could do about Shi Yuan for a while.

"Okay, okay, I don't give it to others...... You didn't come to me just for this, did you? Although Shi Yuan didn't know why Lin Yingyue would treasure those flower cakes, he still agreed.

"Of course, there are other things...... Let me ask you, where did you pass poems across the bank of Mingyang Lake and Fenglai Lou yesterday? And the woman in white who helped you today, how did you meet? "This is the real reason why Lin Yingyue came to Shi Yuan! Back in the room, Lin Yingyue originally wanted to check those account books, but she couldn't forget what she heard about Shi Yuan in Qingfeng Pavilion today. and the woman in white who later called Shi Yuan upstairs, and I don't know how Shi Yuan knew her...... The more she thought about it, the more irritated she became, so Lin Yingyue came to Shi Yuan's courtyard to ask what was going on.

Lin Yingyue asked two questions one after another, Shi Yuan didn't know why Lin Yingyue suddenly asked himself these questions. It was regarded as Lin Yingyue's curiosity and told her about yesterday's events.

Lin Yingyue listened to Shi Yuan's words quietly on the side, and it wasn't until Shi Yuan finished speaking that she said with a smile: "That Shen Wei is a strange woman, you actually play tricks on people like this!" Don't be afraid that the talents of Jinling will trouble you! ”

"Hey! Miss Lin, I was put on a stand by her yesterday, why are you still helping her speak! Shi Yuan said with a depressed face.

Lin Yingyue didn't care about Shi Yuan's words, but continued again: "In this way, you and the woman in the Qingfeng attic are only new acquaintances...... So why did she help you today? And what did she say to you upstairs today? ”

"Damn! This chick is here to check the account, right? How does it feel like a wife questioning her late husband...... This chick can't be jealous, right? Shi Yuan thought so, and immediately denied his thoughts: this chick and himself have only known each other for less than two days, and no matter how narcissistic he is, he will not think that this chick likes him.

Just when Shi Yuan was secretly guessing Lin Yingyue's intentions in his heart, Lin Yingyue on the other side was also complicated in his heart: What's wrong with him? How do you ask this?

"Well...... I don't know, maybe I'm too charming! Shi Yuan didn't guess Lin Yingyue's purpose, so he opened his mouth and snorted.

When Lin Yingyue heard this, she was not embarrassed to ask anything after all, she just snorted coldly and did not speak again. Instead, he pointed to the "pencil" on Shi Yuan's desk and asked, "What is this, I see the ...... you wrote just now?"

When Shi Yuan heard that Lin Yingyue didn't ask any more questions, his heart was inexplicably relieved, he picked up the "pencil" on the table, smiled and said: "This is called 'pencil', which is made of charcoal powder, and it is much more convenient to write than a brush...... Shi Yuan said, found a blank piece of paper, drew a puppy casually, and then said with a smile: Good painting, good painting!

Lin Yingyue sneered and laughed: "You are really thick-skinned!" The painting is ugly, what kind of painting is this...... But this pencil is a good thing! ”

Shi Yuan didn't feel the slightest embarrassment, took the pencil in his hand and said: "Miss Lin is really discerning, if this pencil is energy-producing, it will be of great benefit to the world's readers!" And our Lin family can also make a lot of money with this! ”

When Lin Yingyue heard Shi Yuan say "Our Lin family", her heart suddenly jumped, and an inexplicable joy flashed, and then she didn't say anything, but shook her head and said: "Although this pencil is easy to use, no one in the world will use it, because the imperial examination is not only about poetry and articles, but also about calligraphy achievements!" If you use this pencil, I am afraid that it will affect the results of the imperial examination. ”

Lin Yingyue said slowly, and Shi Yuan immediately understood: this is a world where liberal arts are supreme, the scientific process of industrial manufacturing is abandoned, and the use of pencils is naturally unleashed! The so-called everything is inferior, but only reading is high. Even the Lin family, which manufactures scholarly ink treasures, does not have a high status...... The Lin family is just a merchant after all! How ironic is that? Shi Yuan couldn't help but think of the sentence "Those who are covered in clothes are not silkworm breeders!" ”
