He pointed to the engraving: "The carvers in our workshop are skilled, and we can carve such a plate in one day." This engraving is kept, and you can print as many as you want. The more you print, the lower the cost. ”

This is also the reason why the Four Books and Five Classics on the market are much cheaper than other books in terms of price. Because of the high demand, every printing workshop has engraving, and if there is a shortage of goods, you only need to take out the engraving and print it. Because of the large printing volume, the cost is low, and the selling price is naturally low.

Other scarce books are expensive to print, so it is better to have someone copy them by hand.

Coming out of Cao Ji's workshop, Du Jinning did not go home, but followed Guan Jiaze to Guan Mansion and asked to see Guan Lehe.

Not long after Guan Lehe returned home from the academy, he heard a report from someone that his little disciple was coming, he was very surprised, and let people pass Du Jinning to come in and ask her, "What's wrong?" ”

Du Jinning said: "Teacher, I just printed it from Cao Jishu, and I want to tell you something. ”

"Oh." Guan Lehe pointed to the chair, "Sit, sit down." ”

Du Jinning sat down and said, "The people who printed Cao Ji said that the movable type printing they use is still cement or woodcut, because it takes effort and is not used, and the cost is high, so they don't like to use it. I thought, if you make a mold, pour lead water into it, and make it into lead characters, will it be durable? A workshop, spend a little money to make hundreds of thousands or even hundreds of thousands of words, and there will be no other costs in the future. Because the lead font is durable, there is no problem with tens or hundreds of years, and the workshop can be sold to others if it is not opened, which is a kind of fixed asset, even if the cost of starting to make the word mold is larger, it should be acceptable. Besides, there is no need to cast so many words at once, print a book and cast a book, and the small amount adds up, and the word mold will naturally increase. At most, it is just that there is not much money to be made in the early stage. ”

Guan Lehe's eyes became brighter and brighter as she spoke, and in the end, he looked at Du Jinning with a strange gaze, as if he didn't know her.

Du Jinning was furious by him, and said with a dry smile: "Teacher, why do you look at me like this?" ”

"I see how your little head grows, you can always come up with things that others can't think of." Guan Lehe said with emotion.

Du Jinning felt weak in his heart, touched his nose and smiled without making a sound.

After expressing his feelings, Guan Lehe asked Du Jinning: "Since you have come up with this method, why don't you open a workshop by yourself like opening a teahouse?" I heard Brother Ze say that your teahouse can make money, and you can have dividends of dozens of taels of silver every month. You have a lot of shares, and if you continue like this, in just one year, you can open such a printing workshop yourself, why do you tell me this method? Aren't you afraid that I will swallow your method? ”

"Teacher, you are a gentleman, how can you do such a thing?" Du Jinning slapped a sycophant.

"You can't have the heart to hurt others, and you can't have the heart to prevent people. Although I am your teacher, I don't know people and faces, but I don't know my heart, maybe I am greedy? Guan Lehe still refuses to relent.

"I believe in the teacher." After Du Jinning finished speaking, in order to emphasize this point, he nodded very hard.

As the saying goes, a thousand wear it, but you don't wear it. Although Guan Lehe is a decent gentleman and doesn't like to pat the horse, he is still comfortable by Du Jinning's sycophancy.

"You!" He pointed Du Jinning with his finger, and his smile was quite doting on the juniors.

He leaned back in his chair and asked, "What do you want?" ”

Du Jinning stood up, straightened his clothes, and bowed solemnly to Guan Lehe: "If the students come up with this method to reduce the cost of book printing and let more children across the country be able to read and write, it will not be in vain that the teacher Jinning will bring me out of the mountain village and teach me a lesson." The method of pencil printing is entirely up to the teacher. ”

This seems to be a high-sounding statement, but it is also Du Jinning's heart.

Since she has traveled to this era and knows this method, it is impossible for her to hide this method and only use it as her own money-making tool. Popularizing this method for the benefit of the people can be regarded as a reward for God to let her be reborn. Anyway, she has a lot of modern knowledge in her head, and it's all wealth. If you want to make money, you can rely on your own ability. She doesn't seek to be rich and expensive, but to be rich and secure.

In addition, she also knows that if she covers this method of printing with lead characters to make money, it will inevitably cause a lot of trouble. After all, she has no foundation, no background, and having such a secret is equivalent to a powerless child holding a golden job bowl in the downtown area, which is to invite trouble and find death.

The last time she told Guan Lehe about the tea-making method, it was the same thing.

Guan Lehe was deeply moved by Du Jinning's words.

He looked at Du Jinning movingly, and praised repeatedly: "Good boy, good boy." ”

After blinking his eyes and calming his mood for a while, he said: "However, even if I find a way to get someone to hand the emperor an excerpt and explain this method, the emperor will let the royal family use this method to open printing workshops in various places." The cost of printing has fallen, but whether the price of books will fall depends on the conscience of those who do it. Rather than letting others make profits, it is not known whether it will benefit others, so it is better for us to do it ourselves. ”

He looked at Du Jinning: "I will let people try the lead casting method first, and if it is feasible, we will open printing workshops in various places." When the time comes, the profits from these workshops will be divided into 10% of your shares. Do you have any objection to this? ”

Du Jinning shook his head: "The student said it just now, but it is up to Mr. to decide." There was no objection from the student. ”

Guan Lehe's gaze at Du Jinning was extremely kind.

One percent of the elements, for people who don't understand this industry, may feel too little. But Du Jinning didn't feel wronged at all, it can be seen that he is an open-minded person who doesn't care about gains and losses. But also, if he is a person who values the gains and losses of interests, he will not take out this method and want to dedicate it to the country.

But for the Guan family, it takes a lot of manpower, material and financial resources to do this in the early stage, and there are really a lot of components.

"In the future, when you take the palace exam, the emperor will ask you to write a strategy, and you can also write this method on it, without worrying about our family's business. The Guan family touches your light, and it is enough to make money for a few years with this method. He added.

When he said this, he was also well-informed, and as soon as he heard what Du Jinning said, he felt that it was feasible, so he said so.

"Yes, sir." Du Jinning did not refuse, and directly agreed.

As for what happens in the future, that's for later, and there's no need to discuss it now.
