Kaichi returned to his lodgings with a large stack of parchment, the smell of which made him feel uncomfortable.

Although all parchment paper has been treated to remove odors in the past, it cannot be completely removed, especially after a long time, the smell will be stronger.

March was reading a book on the balcony by the sunset, and the red glow was scattered on Marchi's body like a light veil, and he felt that the color of his hair had changed.

She saw Jia Yi walk in with the scroll, put away the book, and looked at Jia Yi on the balcony, her chest was crushed and deformed.

"Jiayi, why do you come back with so many exercises every day, isn't it too complicated, fortunately, Professor Linna is not like you, otherwise we wouldn't be miserable. ”

Jia Yi looked up at March, now that the elf rice is on track, Jia Yi doesn't have any new projects, and March is idle except for studying.

"March, are you okay now?" said Kaichi tilted his head and smiled a little flatteringly.

March looked down at Jiayi, her long hair hanging down, but because her hair was a little naturally curly, it looked a little messy, and she didn't have the soft feeling of long hair hanging down.

"What do you want to do? Haven't you been teaching students lately?"

Feeling a little tired from looking up and talking, Kaichi released his levitation technique and flew up to the balcony and landed next to March, where he put the test questions aside.

Stared at March, and said, "This, I'm teaching students, but don't you have nothing to do? ”

March got back into the chair, spun around on one of the legs, and faced Jiayi, "What do you want to do?"

After speaking, she looked at Jia Yi suspiciously, Jia Yi has always wanted to do something, but she has never come to discuss with herself, is there any difficulty this time.

Jia Yi also had this idea just now, he wanted to make a little blank paper out to facilitate himself, but he didn't have much time for himself, and the white paper actually didn't have much technical content, and it didn't help much for magic, so Jia Yi didn't think about catching it all in his own hands.

However, the benefits in this area are quite large, if you can make a blank paper to replace the daily paper, just charge the patent fee is enough to make a lot of money, although the unit price of this thing is not high, but the use of a large amount of ah.

The most profitable thing in the world has never been luxury goods but fast-moving consumer goods, and the market base is there.

Jia Yi stretched out his hand and pulled a chair from the room and flew over, and sat in front of March: "Recently, I have used a lot of paper for my students, and some people can't even afford parchment, so I wondered if I could use ordinary paper instead, which is cheaper." ”

It's not that some people can't afford to use parchment, learning magic consumes a lot, and ordinary people don't have this opportunity, but there are always people who will smash pots and sell iron to support their children, hoping to have a good future.

When Jia Yi was grading his homework, he saw someone scrape off the written words with a knife, and then write them again, because the scraping was not very clean, so there was a little smudge when he saw it, and even some of the parchment was scratched.

The thickness of the parchment is limited, even if the original writing is scraped off, it can't be used a few times, Jiayi didn't pay attention to it, and then saw that the parchment had been scratched, but the other party carefully avoided the place where the groove was, and he gradually understood.

He can only write as neatly as possible in the test paper for marking homework and the handwriting is smaller, not taking up too much space, there is no scholarship at this time, and it is not very friendly to some poorer children.

However, March didn't know Jiayi's thoughts, he looked at Jiayi suspiciously: "Use paper, this quality is too poor, the handwriting is pasted, and you can't read it clearly, how to use it?"

"So, I thought if I could improve the papermaking process and make the paper better, so that it can be used more by everyone, although the parchment paper is good, but it is too expensive. ”

Kaichi dragged his chair closer to March and said to her.

He took the parchment book in March's hand, put it on his hand and patted it, making a snapping sound: "You see, this book is only a few words, tens of thousands of words, just such a thick one, if you can use thinner paper, coupled with good printing technology, the thickness of this book will definitely be greatly reduced, and the cost will be much lower." In this way, the price of books will also be much cheaper. ”

At this time, the price of books was not cheap, even ordinary books, such as knight novels, were not cheap, and the slightly more expensive ones were often used in gold coins.

This is mainly due to the fact that the sales are not high, so the cost of book printing is very expensive, which also leads to the fact that the length of the general book is not very long, even if it is a long knight novel, at most tens of thousands of words, and the novel that can exceed 100,000 words can still be sold, which shows that the other party is a very best-selling novelist, and the writing is really good.

If it were like the online texts that Jia Yi read in his previous life, a novel of three or four million words at every turn, no one could afford to buy it at all, and a book would fill a shelf.

March asked curiously, "Then what are you telling me to do? Do you want me to help? It's not impossible, you always have a lot of ideas." ”

"This is not just about helping. Garnishes handed the book back to March and rubbed his hands, "I want you to be in charge of this." ”

"Am I responsible?"

March used two interrogative sentences in a row to express her surprise.

"I don't know how to make paper, so why don't you do it yourself?"

Jia Yi said helplessly: "How can I have time, I want to substitute for a teacher, this is the task assigned by the teacher, and if you are lazy, I'm afraid Professor Linna will also go back and get angry." The last time I took too long a vacation, some professors already felt dissatisfied, feeling that they had wasted so much time on private matters, and they didn't look like a student. ”

Jiayi felt as if he had been cheated, he wanted Orlando to make a move at the time, but he didn't expect it to become himself in the end, but this leave was given by his teacher on his own initiative, but he didn't expect to come back and say it for too long, which no one could predict.

Seeing that March was a little tempted, but a little annoyed, Jia Yi added: "I'll help you, I'll give you some technical solutions, and you just need to follow along when the time comes." It doesn't matter if there is a problem, it is a slow trial and error, and all the results are slowly tried and tested in this way. You see how many difficulties we encountered when planting elf rice, didn't they all solve it slowly and plant the rice well. ”

March felt a little moved, but still a little uneasy: "You won't ignore it then, will you? When I encounter any problems, I will find you and say that you don't have time, let me solve it myself." ”

"How could it be. Jia Yi hurriedly shook his head, "Papermaking is a good thing, how can I give up those credits, if I can make cheap white paper, then it must have a great effect on the promotion of knowledge, and it will also be of great benefit to the academy." When the time comes, everyone will remember us, even if we are not legendary mages, we will definitely be able to leave a strong mark, and everyone who uses blank paper will remember our name. ”

As soon as Jia spoke, he began to think about it, as if he had really seen this day.

In fact, he benchmarked himself against Cai Lun, and Cai Lun did not invent white paper, but improved white paper, making paper a real utility.

Although in modern times, Cai Lun has become a symbol in history books, but hundreds of years ago, Cai Lun's position in the hearts of readers was unshakable. Even if someone slanders Kong Meng from the bottom of their hearts, no one dares to say that Cai Lun is not.

However, the biggest credit for giving the lead to March is also March's, so it's a little disappointing to think about it.

However, thinking that Cai Lun was a eunuch, Cai Lun subconsciously covered his crotch, and when he thought about it like this, there seemed to be nothing unacceptable.

Although eunuchs have nothing to do with papermaking.
