Zhao Yuan, who was immersed in compiling the textbook, seemed to have lost track of the time, and it was not until Tao Pulai informed him that all the wasteland had been reclaimed halfway through, and Zhao Yuan realized that it was the end of February.

During this period, in addition to celebrating a birthday for Luoluo, who turned five, Zhao Yuan was busy compiling teaching materials.

"Brother Yuan, you've written so many books, are you going to start looking for someone to copy them?" Meng Ying looked at Zhao Yuan's achievements during this period of time and asked.

"Looking for someone to copy the book?" Zhao Yuan frowned, ignoring the biggest problem in the spread of books in this era.

"That's right, you have to find someone to help you copy the books, otherwise there are so many books, and it will cost too much money to find the printing house to engrave the engraving." Meng Ying, who already had a lot of knowledge, said a little strangely.

"I'm so busy that I forgot that these textbooks can't just be written." Zhao Yuan patted his forehead, and the ink on his hand hung on his forehead.

Books in this era were very precious, and most of them were controlled by some wealthy families, and it was rare for commoners to see them.

Commoners also mainly obtained books by copying, and the books sold in bookstores were too expensive, but civilians often could not find books to copy.

"It seems that I need to build a printing shop, otherwise so many books, just by hand, I don't know when I will copy them, and there may be mistakes in hand-copying." Zhao Yuan said in a low voice.

After the printing workshop, especially the printing workshop using movable type printing, is built, it will touch the interests of the wealthy families, and the wide dissemination of books will break the monopoly of the wealthy families on knowledge and threaten their status, so it is a very risky thing.

"No matter what, the cement has been figured out, and then a movable type printing is made, it doesn't matter." In Meng Ying's eyes, Zhao Yuan seemed a little chattering at the moment.

"Xiaoying, don't you think it's more idle, I'll find you something to do, how about it?" Zhao Yuan said to Meng Ying with a smile.

"Okay, Brother Yuan, what should I do?" Meng Ying asked with a smile.

"Let's set up a printing office, and in the future, you can help me print all the books I 'write', Xiaoying, how about it?" Zhao Yuan said.

"But I don't understand it at all, and there shouldn't be anyone in our Gray Plains Town who understands it, and the books used in the academy in the bazaar in the past were all hand-copied by them." Meng Ying wanted to help Zhao Yuan, and when she heard Zhao Yuan's words, she said embarrassedly.

"It doesn't matter if you don't understand, just if I understand, I'll teach you." Zhao Yuan said with a smile.

Movable type printing, the need for movable type seals, ink, paper, although these things Zhao Yuan can find ready-made, but in Zhao Yuan's opinion, the quality is inferior.

"It seems that better ink and paper must be made first, and as for movable type for printing, it can be carved with cork in the first place, and later when there is a condition, it can be made with newly produced steel." Zhao Yuan pondered.

"It's another big stall." Zhao Yuan couldn't help but have a headache.

"What's wrong, uncle?" Seeing that Zhao Yuan was thinking about it and began to sigh again, Luoluo came over and asked.

"Does Luoluo also want to help Uncle Ao?" Zhao Yuan asked with a smile.

"Of course you have to help, uncle, how do you read my handwriting?" The little girl, like Zhao Yuan, has become a flower cat at this time.

"Okay, let's do some experiments."

"Is it the same as the experiments we did before?" Luoluo asked in surprise.

"Almost, Xiaoying, you are also with you, this has something to do with the upcoming printing office."

"Okay."

Zhao Yuan took Meng Ying and Luoluo to sort out the results of this time, and a thick stack of manuscripts was placed on the desk in the study, smelling the scent of ink that filled his nose, and his heart was satisfied.

Since the invention of papermaking, the method of papermaking has not changed much, Zhao Yuan is ready to combine the knowledge of later generations, on the basis of the existing papermaking technology, ready to improve the method of papermaking under the existing conditions.

First, the existing paper is a luxury product, and if the book is printed, the consumption of paper will occupy a lot of cost.

The second is that the quality of paper is really not good, and the fibers contained in the paper are very coarse, and the ink often runs when written in ink.

There is also the formula of ink, and Zhao Yuan plans to develop ink making into a pillar industry in Gray Plains Town in the future.

The mountains and forests in Danling are mostly pine forests, and they are also pines with high oil yield, which can provide a large number of raw materials for ink production.

Moreover, there are many tung oil trees in the territory, and Zhao Yuan believes that only by doing a few more experiments can he make some good ink.

"Movable type printing, or use ink is better." Zhao Yuan whispered.

……

Yangchang Town, Dead Man's Slope, here is the largest piece of wasteland bought by Zhao Yuan, after measurement, the area reached more than 3,200 acres, and most of it has been reclaimed at this time.

"Uncle Wu, do you always say that such land needs to be cultivated, look at the grass here that doesn't even grow, it's all sand." A young man said to an old man.

This old man is a well-known local farmer in Yangchang Town, named Wu Zhifan. His family had no land, so he supported a large family by renting other people's land.

When the children grew up, the tenant land was planted for the children, and it happened that Tao Pu recruited the farm manager, and someone recommended him, so Tao Pu invited him over.

"This land is grass in your eyes, but in the Workshop Army, it is a treasure!" Wu Lao said with a smile.

As a farmer who has been growing land all his life, Wu Zhifan knows how to make a piece of land produce more food. Although he couldn't summarize the truth that "every crop is a flower, it all depends on fertilizer", but he knows that the method of farming in the workshop is better than his own.

"Work hard, people like this are the ones who do great things, don't just think about taking that little salary, learn more about the methods of cultivating the land in the workshop, and you will benefit from it in the future!" Wu Lao said to the young man.

Wu Zhifan looked at his three sons and daughter-in-law who were working hard in the field, and he was very satisfied with the current job, and he was infinitely grateful to the workshop army and Lord Zhao, who was constantly in the mouth of the workshop army.

"I must learn the counting method that the workshop army and the pottery steward said, and I can buy land and become a landlord after a few years." Wu Zhifan, an old farmer, thought of his lifelong wish to have a piece of land of his own.

More than 21,000 acres of land are divided into 14 pieces, that is, in 14 places, which means that 14 old farmers like Wu Zhifan who know how to farm and have a certain amount of knowledge are in charge, which was once a very nerve-wracking thing for Tao Pu.

However, with the continuous advancement of land reclamation, things seem to fall into place, no matter how small the land is, a good steward has been found.

"It's time to go and talk to the owner, and the land can start planting!" Tao Pu, who had just completed a new round of inspections, pondered.

Due to the fact that the location of the land purchased is not very good, most of them are still very poor, and of the more than 21,000 acres of land, less than 1,000 acres can be reclaimed into paddy fields, and the rest can only be dry land.
