In the blink of an eye, in the middle of December, the children who had studied for a cold season had mastered the basics, and Lin Yan felt that their learning speed was amazing.

As long as it is a new knowledge point, say it again, and they will soon be able to absorb it and extend it to new ones.

She didn't have to bother to tell in detail at all, and now they have undergone a metamorphosis, their minds are filled with all kinds of knowledge, and their imagination is rich every day.

I want to use what I've learned to create something new.

Lin Yan taught dry goods, and the rest was understood by themselves and confirmed in practice.

"The cold season is still half a month away, and this year is about to end, do you have any plans for next year?"

Hua Min smiled and said, "I haven't thought about it yet." Seeing that you are so happy, do you have a new plan? ”

Everyone else looked at Lin Yan, she was indeed different today, wearing a snow-white leather coat, fluffy, sparse yellow hair was also tied up, and she looked full of energy.

"Lin Yan, what do you want to do?" Shi Zhi's eyes rolled, and he simply asked. He felt that Lin Yan had too many ideas, and it was too difficult to guess.

Shui Sheng raised up and looked at Lin Yan for a while, feeling that she was going to do something big again.

Ye Cong walked up to her and turned around before saying, "Lin Yan, you look so good today, I also want beautiful clothes to wear." ”

"Haha, Ye Cong, you are also good-looking, your skin is much whiter." Lin Yan laughed, not to mention, after a cold season, the children's tanned skin was whiter.

There is no need to withstand the scorching sun of the hot season, nest at home and not go out, but the skin has whitened a lot.

"Am I really white? Is it the same as you? Ye Cong asked.

Lin Yan is the whitest of them, although she will also tan, but she is still young, and she can protect herself from the sun, she may eat well in this cold season, and she is white and fat, and she is the best-looking little doll in Sun City.

Shi Zhi looked at Ye Cong and said directly: "How can you compare with Lin Yan, look at your hands, and then look at Lin Yan's, you will know the gap." ”

Ye Cong looked down, and immediately deflated after comparison, "It can't be compared, it really can't be compared." ”

After everyone laughed, Lan Yue asked, "Lin Yan, what is the plan you just said?" ”

The others quieted down and stared at Lin Yan.

She said: "You have learned so much, and you will put what you have learned to good use next year." The reason why I chose you to take classes is because I am smart and can remember what I have learned, but after a long time, some things will be slowly forgotten. ”

Shi Zhi raised the slate in his hand, "Isn't there a record, my house is full of slates, all of which are records that I usually make, and they will not be lost." ”

Hua Min said: "Although the slate can be recorded, it is too cumbersome, and the things written down with charcoal will slowly blur. I also traced all my notes a few days ago, but I was afraid that the handwriting would be lost after a long time. ”

"yes, I found it too." Ye Cong hurriedly followed.

Others nodded one after another, the slate record does have many shortcomings, and the most feared thing is that it will fade after a long time, and the handwriting will be blurred, so if you don't notice it, you have to write it again.

They noticed these shortcomings, but they couldn't think of a better way.

They looked at Lin Yan expectantly, since she said so, there should be a way.

Huang Ying couldn't help but say first: "Lin Yan, you have a better way, talk about it quickly." ”

"Okay, let's stop selling it." Lin Yan looked around with a smile, they couldn't help but beat people, and she felt that the time had come.

"In fact, there are many kinds of carriers for recording words."

"Variety?" Everyone was shocked, they didn't come up with any of them, there were many more.

Lin Yan nodded, "There are indeed many kinds, you will see them later." Let me start with bamboo slips and paper. Bamboo slips are bamboo pieces made of bamboo, and the text is engraved on them, and the preservation time is also long, but the disadvantage is that it is heavy, cumbersome to make, and inconvenient to transfer. ”

"What about paper, what is that?" Hua Min was very curious, the first time she heard about paper, the bamboo slips could still be understood, and she looked at the appearance of Lin Yan's painting on the slate, which was very vivid.

"Paper is made of various fibers through a complex process, light and easy to use, written with a special pen, and can be stored for a long time. When the paper is bound into a book, there is a book. A book can be passed on better. ”

"What does it look like?" The more Hua Min listened, the more confused she became, and she didn't understand it anymore.

The others were also question mark faces, and they didn't know what Lin Yan was talking about.

Lin Yan felt that he had overestimated them, he had never seen the real thing, and no matter how he described it, it was still very abstract. She immediately decided: "Okay, I can't say it clearly, then I'll understand it when I make it." ”

"Make it? When do we do it? Hua Min said eagerly. It's so important, especially since they have learned so much and want to teach more people.

Aquatic asked, "Do you know how to do it?" What do we need to prepare? ”

"I know the process, I've never done it." Lin Yan is also very regretful, paper has a long history in the history of human civilization, and it is very common in the later period, who would have thought of doing it in person.

"So, next year we will work together and keep experimenting to make paper. Regardless of the quality, make it first and then improve it slowly. ”

"Okay, okay, I'm with you." Hua Min was very positive, she wanted to see what Lin Yan's magical paper looked like.

Shui Sheng also followed and said, "I'm with me too." ”

Others are not to be outdone and are very active to join.

If you can make paper, that's a new beginning.

Lin Yan said: "I just want you to do it together, I don't know when I can get it out." Not only do you have to make paper, but you also have to make pens. The charcoal I use now is too thick to write on paper. Therefore, our task next year is not only to make paper, but also to make pens, which is a difficult task. ”

"With you, we can do it." Ye Cong admires Lin Yan very much, and believes that it is not a problem to have her.

Hua Min also agreed, "You know what to do, we will definitely be able to do it." ”

"It's just that we already know the general process, and if we can't do it, wouldn't it be too useless." Huang Ying followed.

Bai Chen: "Paper is so easy to use, what materials do we need to prepare?" ”

Everyone else stopped, staring at Lin Yan, eager to immediately plunge into the experiment.

"Let's start with the straw paper, this one is the easiest. As the name suggests, straw paper is made of grass, and we will find more reeds and weeds to try. Speaking of the improvement of charcoal, it is not very easy to use it when burned on the fire, Mao Mu and Lin Yun, you two have experience in burning products, first use the kiln to burn some charcoal out, and then we will find a way to improve it......"

Hearing that paper is made of weeds, everyone else was shocked, can grass make paper?

But looking at Lin Yan's confident appearance, they suppressed their doubts in their hearts and continued to listen to Lin Yan talk about the principle of papermaking.
