However, Li Shimin and Fang Xuanling have the difference between this. Now, the whole book needs to be carved out by printing the book, and the effort it takes to be imagined.

But if it is used to combine movable type, wouldn’t that mean that if you want to print a book, just arrange and combine individual characters?

That means printing books will be much easier in the future and the cost will be much lower.

Nowadays, the price of a book on the market is really not cheap, and most people really can't afford it!

Kong Yingda was excited when she heard this, "Yes, each word is engraved separately and then arranged in combination and arrangement, and the cost of printing the book will be greatly reduced. Why did no one think of such a simple idea before?"

Chu Suiliang said excitedly: "Yes, the price of books will not be so expensive in the future. Those poor students can also afford books!"

This hit Li Shimin's itch. The more students from poor families, the more beneficial it will be to the court, because it can break the monopoly of the aristocratic families over talents.

However, just when everyone was excited, Wei Zheng poured a basin of cold water and pondered: "Not anyone has thought about it like this, but the woodcut characters are easily deformed and rotten when they encounter water, so after trying it, I found that this road cannot be done at all."

Everyone who was a little excited was immediately poured a basin of cold water. It turned out that someone had thought about it and tried it, but found that it couldn't work at all.

Li Shimin couldn't help but sigh. Although he had always thought Su Cheng was amazing, someone had tried it before, which meant Su Cheng was destined to fail.

Changsun Wuji had a sudden inspiration and pondered: "The wood is easily deformed and rotted when it comes to water. Can you use something else?"

Wei Zheng shook his head slightly and said, "We are just speculations. Those craftsmen take this as a career. If they could use other stereotypes, they would have discovered it long ago!"

Fang Xuanling and others could not help but nodded after hearing this. Although Wei Zheng was good at pouring cold water, he had to admit that his pouring made sense.

Li Shimin said helplessly: "It turns out that this kid is also stupid. You kid are messing around in the workshop, and you don't even come to summon him!"

Fang Xuanling smiled and said, "Duke Rong is extremely smart enough to think of this. It is normal for him to not know the inside story. After all, there is no workshop for printing books at Duke Rong's house."

After hearing this, the eunuch finally understood it. He hesitated for a while and said boldly: "Report to Your Majesty, I heard from the people in the workshop that Duke Rong is looking for some copper plates, lead and water."

Li Shimin was stunned when he heard this and said happily: "Oh? So Su Cheng didn't use woodcuts as carvings? Haha, I just said that this guy is so wise, how could he not have imagined that woodcuts are easily deformed when they encounter water? It seems that he discovered that using something else instead of woodcuts!"

Fang Xuanling and others couldn't help but mutter in their hearts after hearing this, saying that the emperor didn't say that just now.

However, it is not the time to slander. They were also happy after hearing the eunuch's words. If Su Cheng succeeded, it would have a great impact on scholars all over the world. It would definitely be a feat that was famous in history.

It's not even less than the contribution of great success!

Now even Li Shimin couldn't sit still and stood up and said, "Let's go and see if Su Cheng can succeed!"

Can it be successful with copper and lead?

Fang Xuanling, Wei Zheng and the others are not sure, but that's Su Cheng. When did Su Cheng fail?

Li Shimin walked out of the hall with great strides, Fang Xuanling, Wei Zheng, Chu Suiliang, Kong Yingda and others followed closely behind.

In the workshop, the craftsman had already engraved a word, just a simple word "zhi". Just as he was about to continue engraving, Su Cheng smiled and said, "No need to engrave it again, one word is enough, just give it a try. If it succeeds, it will not be too late to engrave again in the future."

Wang Shengnan nodded slightly and smiled: "Yes, if it succeeds, it will not be too late to get another move!"

"Have the lead water boiled?" Su Cheng asked.

"It's ready, it's ready!" the manager said quickly.

"Populate the lead water and be careful!" Su Cheng ordered.

The craftsman carefully poured the lead water on the engraved copper template. As time passed, a square lead type gradually took shape.

Wang Shengnan said in surprise: "Success! Success!"

"It must be successful!" Su Cheng was also very surprised, and a lively scene appeared in his mind, thinking about it with great enthusiasm!

However, thinking about this in front of Wang Shengnan seemed a bit unauthorized, and Su Cheng quickly stopped thinking.

Exchange good books and follow the vx official account. Follow them now and you can receive cash red envelopes!

"Print it and try it can do it!" Su Cheng said with a smile.

"Yes, yes, try it quickly, try it quickly." The manager said quickly.

A craftsman took out the lead type with a hint of heat and prepared for the test.

The lead type was printed on the paper, leaving a word "一".

The manager and the craftsman were immediately excited and shouted excitedly: "It's successful! It's really successful!"

Su Cheng couldn't help laughing: "This is very simple!"

After saying that, Su Cheng couldn't help frowning, looked at it carefully, and said a little dissatisfied: "This moji is not very good, is this okay?"

The craftsman hurriedly said, "The National Lord doesn't know that the ink used for printing books is not for writing, but specially prepared ink. Now this ink is definitely not suitable for lead type, but the formula of the ink will be improved later."

So that's it, Su Cheng asked quickly: "You still need to improve the formula of ink? Is it easy to do?"

The craftsman nodded confidently and said, "It's easy to do, it's easy to do. You can definitely try it out in less than ten days or half a month!"

These craftsmen are all masters. Since they said they could try it out with such certainty, they must be very sure. Su Cheng was very happy when he heard it: "So, is the movable type printing technique done?"

It's very simple, and it's not clay or wood, but it's just lead type in one step!

Wang Shengnan blinked his eyes at Su Cheng and asked curiously: "How do you know how to use lead?"

Su Cheng smiled calmly and said, "I don't know why, I just know, maybe this is a genius!"

Since coming to the Tang Dynasty, Su Cheng felt that his skin had become as thick as the city wall. Perhaps this is the one who is close to the red and the one who is close to the black. After all, whether it is Li Shimin or Cheng Yaojin, they are shameless.

Is Su Cheng a genius?

If others claim to be a genius, then Wang Shengnan will definitely sneer and feel that this person is overestimating his abilities. However, Su Chengsu himself is a genius. Wang Shengnan nodded in his mind, with a hint of admiration in his eyes.

Because she felt that Su Cheng was a genius, there was no doubt that if Su Cheng was not a genius, then there would be no genius in the world.
