Li Chengqian looked at Cheng Chubi with a confused expression, and then glanced at the seal under the cover.

"Isn't that already obvious?"

Cheng Chubi behaves like Einstein who is about to discover the theory of relativity, and like Newton who is about to be smashed in the head by an apple.

"No, Your Highness, if you cover it two more times, I have an indescribable feeling, it's amazing......"

Li Ke on the side was also full of questions, although he couldn't figure out when Brother Chu Bi wanted to do the demon moth, but now he could only cooperate and whisper instigation.

"Big brother, you can try two more and see what kind of demon moth Brother Chu Bi wants to get."

“？？？” Cheng Chubi was not happy. God's special demon moth, does Lao Tzu want to invent and create?

This is for your brother, so that your brother can surpass that Michelin tire prince.

Become the hottest-eyed, cough, and most dazzling young star in the Tang Li royal family.

After glaring at Li Ke viciously, Cheng Chubi took a deep breath.

Forget it, don't worry about this guy, wait for the great invention that you promoted Chinese civilization to appear hundreds of years in advance, and then have a chance to take revenge on this bad prince.

Li Chengqian looked at his painting with a black line on his face, and reluctantly gritted his teeth and covered it twice.

Cheng Chubi copied the painting, looked at the three vermilion seals neatly arranged in a vertical row, and looked suddenly enlightened.

"Sure enough, I understand, Your Highness...... You're such a genius, hahahaha......"

"Brother Chu Bi, what are you doing here?"

Li Chengqian rubbed his eyebrows, feeling that it was no longer himself who needed to be treated now, but Brother Chubi.

"For Brother Dexian, come, give me your private seal, come, Your Highness, you also give me your seal, and Yu Zhan, bothering you to give me your private seal......"

Although everyone didn't understand what this guy wanted to do, they all took out their private seals and handed them over under Cheng Chubi's frequent urging.

I saw Cheng Chubi use his big hand holding a knife to take out his own private seal.

Then the four private seals were put into the clay box, copied up, pulled a blank tribute paper from the side, and then slammed it hard.

Everyone looked at Cheng Chubi's operation with a black line on their faces and a bewildered face. I saw four private seals of different sizes, all stamped on the tribute paper.

"Do you understand?"

"......" The three heads shook in unison.

Cheng Chubi was unwilling to change the order of the four private seals and stamped them again......

"Do you understand now?" Cheng Chubi swept over the three people, and what he saw was still three blackened and confused faces.

Cheng Chubi looked up at the sky with a desperate face, this special mother's ...... I've been guided to such a point that they still don't understand.

"Didn't you notice? The words on these four private seals are all different. ”

Yu Zhining's face darkened, and he stretched out his hand.

"General Cheng, if you don't say such nonsense, we know it...... I'm tired of you returning the private seal to the old man. ”

"What's the hurry, who would be rare with you, I'm driving you to broaden your horizons and consider new things.

Don't you think that the engraving printing of my Datang is very backward now? ”

"And these four private seals are now providing us with a better idea."

As soon as these two sentences came out, the faces of the other three people changed directly, whether it was the Li family brothers or Yu Zhining, they were all taken aback by Cheng Chubi's words.

"You see, if we say that there are 10,000 or 20,000 characters in the Analects, the font used is only 3,000 or 4,000 characters.

If I carve out these three or four thousand individual fonts, and then use this method, I will print the first page of the Analects, and then on the second page, I will adjust the order of them, adding or subtracting the characters......"

Cheng Chubi was there with a gesture and a spittle, and under the explanation of the flying stars, the three of them had already reacted.

They all looked at Cheng Chubi with a shocked face, as if they had been shocked by the picture depicted by Cheng Chubi.

Yu Zhining's face turned from black to red, and he didn't care about feeling sorry for his long beard that had been pulled off by the shock just now, and he said in a trembling voice.

"Yu understands what General Cheng meant, in the past, engraving and printing must be carved according to the content and format of the book."

"And if it's General Cheng's way, you only need to carve out all the fonts you need separately and fix them with something."

"In that way, no matter what kind of books are of any time, that set of fonts, you can print all those books."

"If it is really feasible, then its cost, compared with today's engraving printing, is simply extremely cheap......"

"This, this is simply the gospel of the poor scholars in the world who suffer from having no books to read......"

Yu Zhining turned his head in a daze, looked at Cheng Chubi, and never thought that this person had always been happy to scare the subordinate officials of the East Palace.

Cheng Ri was fortunate to enter His Royal Highness the Prince, and was a rude and unreasonable martial artist, not only excellent in medicine, but also a genius in poetry.

And today, with a few private seals, you can come up with a brilliant idea to innovate Datang's book printing method.

Although Yu Zhining was born in the family of an official eunuch, he was once in the late Sui Dynasty, and he knew the poor scholars in those places.

It is extremely difficult to read, and the only way to rely on the family and borrow books from them is to worship the wall of a certain master and have books to read.

Even if you are a reader with a little money in your family, if you want to sell a set of classics with a small number of words, you need to hesitate again and again before making a move.

What's more, after borrowing from others, they copy it themselves, why, because the price of books is ridiculously high.

Datang's engraving printing, because the engraving is very difficult, and because the engraving material is mostly wood, it will crack and damage if it is not properly maintained.

As a result, the price of the books printed by the engraving remained high, and after many printings, the handwriting began to become blurred.

Rao is like this, the income earned by the people of Chang'an City from their monthly labor is afraid that it can be used to purchase a set of "Analects".

Hearing Yu Zhining's explanation full of embarrassment and emotion, Li Chengqian and Li Ke became more and more calm.

Li Ke stared at Cheng Chubi with straight eyes, then glanced at the prince brother beside him, and muttered.

"Brother Chu Bi, you brain, little brother, I'm really convinced."

"Could it be that brother, what amazing elixir have you taken? Is it because ...... Because I haven't eaten bear-hearted leopard gall bladder? ”

"......" Cheng Chubi saw Li Ke's stunned eyes, and he was immediately unhappy.

How does this guy's brain grow, is it because he thinks about making up for form all day long? That's not right, the heart and gall have nothing to do with the brain.
