"Because Ying Guogong couldn't afford to pay the 500 yuan, he used a house outside the city and 500 acres of land as collateral, which is also the key to what I can find."

Li Junxian said: "There are still 500 acres of land in this house, and a few days ago there was a change of owner, named Qin Jue, so I suspect that this person is the person who took out the glass bottle and the elixir and jade liquid, and 380 acres of the 500 acres belong to the salt mine, so I suspect that this salt is the handiwork of this person."

It's just that the humble duty found out that this salt mine is a poisonous salt mine, but the salt he refined is the high-grade refined salt, and the humble duty suspects that this person has a special method of refining salt ore. ”

After Li Junxian finished speaking, Li Shimin was silent for a moment, and then said: "This person is twenty wen and a pound of salt, if I send someone to buy it all, can I turn this salt into official salt?" ”

Li Shimin suddenly thought of a point, this salt is good salt, high-grade refined salt, in this case, if Twenty Wen collects this salt and then sells it, wouldn't it be able to make money?

"Your Majesty, I'm afraid this matter will not work, because this salt needs to rely on household registration certificates, and each person can only buy one catty per month!"

Li Junxian said truthfully to Li Shimin: "This is also the reason why this salt can be sold normally, if there is no such regulation, this salt would have been bought by all people a long time ago." ”

"What? And such strange regulations? ”

Li Shimin's eyes suddenly flashed, as if he had thought of something, and then said, "This guy's courage is really big." ”

It's just that Li Shimin didn't say anything, but waved his hand at Li Junxian.

Li Jun retreated with envy.

When Li Junxian retreated, Li Shimin didn't have the heart to continue to watch the twists and turns, and said to himself: "It's really interesting, this move is ruthless enough, it cut off the wealth of the family and the nobles at once, and put the salt industry into the hands of one person, I am much easier now, salt is the lifeblood of the world, how can it be controlled in the hands of others?" ”

However, Li Shimin did not dare to act rashly, first of all, this person used Cheng Chumo to be the person in front of the scene, and he operated behind the scenes, which can be described as exquisite.

According to Cheng Chumo's status, the family and Xungui didn't dare to move at all, so he could operate well behind the scenes.

"I, I really want to go out of the palace to meet this person, this salt and iron is the most important thing, if the salt can't be held tightly in my hands, I can't sleep and eat."

Li Shimin muttered to himself, and then sighed.

Originally, he could have secretly controlled this person, but if he did this, if he let the family know, it would be bad for him, but if he didn't do this, the salt could not be in his own hands, and this feeling of being stuck in his throat was really not very good.

Li Shimin thought for a while, and then he was ready to meet this guy, if this person really has a good way to extract salt, he must find a way to buy it.

………………

Qin Jue, who was in the manor at this time, naturally didn't know that the palace had noticed him, and he was looking at Cheng Chumo with interest at this time.

At this time, Cheng Chumo was like an apocalypse possessed, and he actually started to do carpentry work.

A serious person is holding a dagger and carving it on a piece of wood.

"What are you doing here?"

Qin Jue was a little curious about what Cheng Chumo did.

"Don't mention it, my artifact was damaged a few days ago, and I'm going to make a new one."

Cheng Chu didn't raise his head silently, and focused on doing his thing.

"Artifact? What kind of artifact are you? ”

Qin Yu was even more curious, this Cheng Chumo looked stupid, but the way he focused was really different.

"When I'm done, I'll be able to guess with your intelligence, so let me sell it first."

Cheng Chumo suddenly raised his head, grinned, and then quickly lowered his head, and the dagger in his hand kept picking up sawdust.

Before Cheng Chumo could finish carving, Qin Jue suddenly frowned, and then said, "You are engraving printing?" ”

Because Qin Jue found that Cheng Chumo carved anti-script characters on this wood, he guessed what he was doing in an instant.

"Block printing?"

Cheng Chumo suddenly raised his head, looked at Qin Jue, and then said: "This name is good, let's call it engraving printing in the future." ”

After Cheng Chumo finished speaking, he lowered his head again and carved it.

"How did you come up with this?"

"I was forced by the old man of my family to study, I didn't want to go to study at all, I wanted to sleep as soon as I read, so the master punished me for copying books, so I was too tired, I was thinking if there was any way to avoid the pain of copying books.

Then one day, I saw someone else copying the stone tablet and rubbing it from the stone tablet, and I thought, if I carved all these words on the wooden board in turn, and then brushed with ink, and then printed it, wouldn't it be much easier for me?

So I started to do this, but I didn't succeed several times, until one day, I used jujube wood, and I knew that if I wanted to print it, I had to find hard wood. ”

Cheng Chumo said to Qin Jue while carving.

At this time, Qin Yu was directly shocked.

Engraving printing began in the early Tang Dynasty and flourished in the late Middle Tang Dynasty, which he knew.

But the inventor of engraving printing turned out to be the fool in front of him.

The reason for the invention was because the Master punished him for copying books!

Qin Jue looked at Cheng Chumo, who was serious, and then said, "Cheng Chumo, have you ever thought about carving out these words separately?" If the Master asked you to copy the Analects today, Mencius tomorrow, and Zhou Yi the day after tomorrow, wouldn't you have to carve a lot? If each character is engraved separately, in this way, it will be good to re-typeset it every time? ”

After hearing Qin Jue's words, Cheng Chumo suddenly raised his head, and then said, "Heavenly Master, you are really smart!" In this case, I can leave a lot of work left! ”

Qin Jue smiled, this is special movable type printing, which is definitely much better than engraving printing.

"Also, you carved it out of wood, have you ever thought about carving it out of something else? This wood is wood after all, and no matter how tight the wood is, it will be too easy to corrode after all. ”

"Heavenly Master, I have also considered this problem, because this template is not the first time that I have been damaged, and it is easy to be damaged if I use it too many times, but there is no way, I can't carve other things, and I have also tried to carve stones, that thing can only carve very large characters, and I copy the book and use the stone to expose the filling."

"When you think of this, have you ever thought about going up to the Holy Hearing?"

As soon as Cheng Chumo heard Qin Jue's words, he immediately said: "No, no, if I tell Your Majesty, it will be bad, I will definitely be hung up and beaten, this kind of thing must not be told to others." ”

Qin Jue was directly speechless, this Cheng Chumo, although he is the inventor of engraving printing, but it was completely developed for copying books, for him, this printing technology is a tool to help him copy books.

He never imagined that this technology would be the most powerful tool for the development of a civilization in the future.
