Although the latter was puzzled, he still honestly took out the seal and handed it over to Ying Changsheng.

I saw Win Changsheng, and with a seal, he dipped it in the ink on the table next to him.

Immediately, on the paper, the cover was down.

On the paper, four clear words of Wu Zhangcang appeared.

"Got it?"

After doing this, Ying Changsheng did not continue, but asked Zhang Liang and Zhang Cang.

The two of them frowned, obviously a little surprised, and they hadn't come back to their senses yet.

Seeing this, Ying Changsheng couldn't help but sigh.

He understood.

For people who have never been exposed to printing, it is difficult to make them realize the simple technique of printing through these means.

For things that have not been touched.

Human beings, after all, lack some imagination.

It's like printing.

It's not a high-tech thing at all.

It is nothing more than engraving printing, which is nothing more than making the seal bigger and then printing.

And movable type printing is not difficult.

It is nothing more than fixing individual small "seals" into one piece, and then printing.

What kind of high-tech stuff is this?

During the Qin Dynasty, it was fully capable of this technology.

However, people didn't expect it, and it wasn't until the Northern Song Dynasty that people thought of it......

I only saw Ying Changsheng explaining.

"On the seal, one word can be printed, can't it be printed hundreds of words at one time?"

"This ......"

Zhang Cang and Zhang Liang, suddenly, only felt a buzz in their heads.

Immediately, the clouds were cleared, and the mouth suddenly opened.

None of them.

It's not that hard at all!

It's just that I didn't think of it before.

Hearing Ying Changsheng say this, Zhang Cang's eyes instantly lit up.

"This is a good skill, using people to copy, after all, the speed is too fast, if you use this method, a set of books, just to complete the engraving, is to print as much as you want, how much will be printed......

"That's right!"

Zhang Liang also bowed his head and looked at the paper again.

"However, after all, this thing is still with the paper, so it can be used to show its usefulness, if there is no paper out, use bamboo slips, but it can't be printed!"

"That's nature!"

Ying Changsheng nodded.

"These two technologies complement each other, and one is indispensable!"

Zhang Cang on the side nodded and sighed again.

"This is really a good thing for the benefit of the country and the people, my Daqin often copies official documents, tired swords, pen and knife officials, their hands are sore, and they can't copy a few copies, and this official document is a copy, hundreds of words, thousands of words, or even tens of thousands of words, when transcribing, but can not make mistakes, once it is wrong, in my Daqin, it is to be punished......"

"In the past, it was written with bamboo slips, and it was written wrongly, and it was possible to use a knife to cut off the typo, and then re-write, but now it is written on paper, and if it is wrong, it has to be rewritten, and with this printing it is different, just write out a sample, let the craftsmen follow the carving, and you can do it......"

"Right!"

Zhang Liang nodded.

He sighed.

"Although there were a large number of books in my home when I was young, there were many errors in them, and even, for the same article, there were some differences between the collections of the two families, which were errors in transcription, but if it was printed, probably there would not be such errors......

"Don't be in a hurry to say this, let me ask you, don't you think, what I just said, is there anything that needs to be improved?"

Ying Changsheng frowned and looked at Zhang Liangdao.

Zhang Liang and Zhang Cang talked a lot, but the two of them were stunned to focus all their attention on what Ying Changsheng just said, engraving and printing.

In Ying Changsheng's opinion, this thing is something behind the times!

The cost is very high.

After all, if you make a mistake in engraving printing, you need to remake the template and then re-engrave it, which is time-consuming and labor-intensive.

"Your Highness, is there anything else you want to say?"

Zhang Liang and Zhang Cang, with a confused face, the two of them can think of engraving printing, which is already rare and valuable, how can they continue to think deeply, think of movable type printing?

Seeing the ignorant looks of the two, it was not easy for Ying Changsheng to continue selling officials, he pointed to the seal.

"This large piece, with hundreds of words, thousands of words on the seal, is time-consuming and labor-intensive, and once a word is wrong, the entire layout needs to be re-engraved!"

"But what can be done if you don't?"

Zhang Liangfa asked.

"Absolutely!"

Ying Changsheng said.

He picked up Zhang Cang's seal and said.

"If you carve out each one, small seals of equal size, each small seal, only one word will be written in it!"

"When it is necessary to print, according to the content of the article, the words that need are selected, composed into an article, fixed, and then printed, so that every time a book is printed, you have to give it to him, and carve out a layout yourself......

"Nineteen sons are talented, Zhang Cang admires it!"

Zhang Cang's eyes lit up, and he said to Ying Changsheng.

Of course, he could realize the power of these things that Ying Changsheng said.

Zhang Liang on the side was also shocked, and he immediately asked.

"Your Highness, are these things complicated to do?"

"Craftsmen, can you finish it?"

"Probably, it should be fine!"

Ying Changsheng and Zhang Cang said at the same time.

Immediately, Win Changsheng didn't talk nonsense, and immediately headed towards Yan outside.

"Go to Shaofu and invite the prince to this son!"

"No!"

Yan Yi answered, and then retreated, going to ask the public to lose the upper creation.

After a while, the public lost and made it in.

"The ministers lost and made up, knock on the nineteen sons!"

The public loses a black dress and respectfully salutes.

"Excuse me!"

Ying Changsheng waved his hand, and then told the latter about movable type printing.

The latter was silent for a moment, and then couldn't help muttering.

"How could I not have thought of such a simple thing?"

Hearing his words, Zhang Liang and Zhang Cang on the side couldn't help laughing.

Well, that's what they thought when they first heard Ying Changsheng mention this printing technique.

That's the truth, it's a very simple thing.

However, they just didn't think it through.

At this time, Ying Changsheng asked.

"Is there any difficulty in proposing this, movable type printing?"

"There should be difficulty, but it's not too much!"

Gong lost and said.

"The difficulty is that this is just an idea, if you really want to make it, you need to conduct some experiments, after all, this movable type printing, typesetting, one by one, how to fix, or, what kind of material, to make this movable type, is also a problem......
