Late at night.

Li Chengqian returned to his East Palace, but was called to the Liangyi Hall by He De.

He was a little confused.

At this hour, my father had already rested......

Is it so abnormal today, is it because I am worried about my sister who is going away for the first time?

But no matter what, his father shouted, and he still had to go.

Inside the Liangyi Palace.

His Majesty Li Er looked at his son in front of him and said in a deep voice:

"Regarding the matter of "Chang'an Daily" before, I asked you to discuss it with Lu Risheng, has there been a result?"

Li Chengqian was stunned.

He thought about it, and it seemed that there was indeed such a thing.

However, what Lu Heng meant to himself later was probably to toss casually, anyway, His Majesty Li Er's strategic vision would definitely not be bad, and they would not be able to continue to build a new bookstore for a while now, so it would not hurt to give it to him.

Thinking of this, Li Chengqian arched his hand and said:

"Father, the son has already discussed with Sunrise, and this technology can be given to you at any time."

"It's just ......"

"Erchen wants to ask, what are you going to do with it?"

Li Shimin was also stunned for a moment.

He didn't expect that Li Chengqian, who had always been obedient to him, would take the initiative to ask about his follow-up plans today.

This was a bit unexpected.

After thinking for a moment, His Majesty Li Er raised his eyebrows and said:

"It's a good thing to know how to ask."

"But you can start by talking about what the technology is all about, how much it costs, how much it will cost to mass-produce, and how much investment it will take to get started."

"Otherwise, I can't say what I have planned, can I?"

After hearing this, Li Chengqian also felt that this was the truth.

So he told the story.

"This technique was researched by Lu Heng himself, and he called it movable type printing."

"Our Datang originally had printing, but it was an engraving made of a whole piece of wood, and most of the uses were to print Buddhist scriptures and other things."

He said that he was inspired by the seal, and changed it, dividing the whole stencil and asking the craftsmen to engrave words on small square clay blocks, and then baked them into a half-porcelain and half-pottery shape.

"Engrave more words that are used more, and engrave fewer words that are not commonly used."

"When it's time to print, just glue the blocks directly into the wooden frame and print them on the paper one by one."

"After printing once, roast the sticky place with fire for a short while, and the block can be removed again, and you can continue to use it later."

"The reason why "Chang'an Daily" can be printed so quickly and in large quantities is because of this technique!"

Li Shimin was shocked and dazed when he heard this.

Although I had guessed before, it must be a very novel technology that allowed Lu Heng to build Tianxia Bookstore and "Chang'an Daily" one after another in a short period of time......

But this movable type printing is indeed a bit beyond his imagination!

The reason why he coveted this technique was because he saw the speed and quality of Lu Heng's books.

The books in the Tianxia Bookstore were sent to His Majesty Li Er as early as the opening of the book, and the text content was all from the East Palace study, so naturally there was no problem. That word, at first glance, is not hand-copied.

As for the "Chang'an Daily", which has only published two issues, it shocked Chang'an City with speed and quantity!

If this technology is in the hands of the imperial court, what is it not fragrant to do?

The national documents distributed to the provincial, prefecture and county governments every year can save a lot of money and save a lot of time.

Not to mention printing books!

Li Shimin was still sitting and listening.

Thinking of this, he stood up directly!

"How many people know about this technology today?"

His Majesty Li Er stared at his son:

"I heard that the bookstore was in the world that day, and the old Cheng family also invested a lot of ......"

"Does his family know?"

Li Chengqian shook his head.

"Father, this matter was done with us, and Lu Guogong didn't actually get involved."

"You also know that he is silent, he doesn't have any heart, he didn't ask, and we didn't say."

"Now, the only people who know this technology are Erchen, Risheng, Yu'er, and those craftsmen who are responsible for printing."

Li Shimin's spirits were lifted.

He asked:

"Are those craftsmen all right?"

"They weren't in the courtyard of your bookstore when they burned down the bookstore?"

Li Chengqian continued to shake his head:

"Sunrise has already placed them in his own small courtyard, and recently asked Erchen to invite someone from the Hundred Horsemen Division to guard them."

"The original arrangement was to put the children of the craftsmen in the Lu Mansion on the outskirts of Beijing, but now that they have left Chang'an, those children will be sent to the Tiger Head Gang first."

"That's right...... Those craftsmen were originally brought over by the Zhang gang leader of the Tiger Head Gang. ”

"But don't worry, they haven't stepped out of the courtyard so far, so it's fine!"

Li Shimin was silent for a moment.

He originally thought that a reckless man like Lu Heng was usually reckless in everything, although he had a bit of God-given intelligence, but he still needed to clean up the mess in many things.

Unexpectedly, the arrangement was quite appropriate.

Half a day.

He said in a deep voice:

"Gao Ming, I gave you an errand."

"Transfer all the craftsmen in that courtyard out of Chang'an City as soon as possible, and find a suitable place outside the city, the place should be large enough for the craftsmen's families to live there, and it should not be dazzling, so as not to be noticed."

"All their daughters-in-law and children were brought back, sent together, and made a home there."

"I will send a hundred horsemen to protect the vicinity."

"The craftsman only needs to work, the money and food are distributed, and nothing else has to be worried!"

Li Chengqian was a little stunned.

He knew that movable type printing was a good thing.

But he didn't expect that after his father heard about it, he would attach so much importance to it.

"Father, can you tell your sons what you are going to do with them?"

After hesitating for a long time, Li Chengqian finally asked again.

Li Shimin looked at his son and said in a low voice:

"Lu Heng handed over this thing to you, thinking that he also hoped to pave the way for you, I don't mind."

"Since you are the prince of the Tang Dynasty, you naturally have to accumulate enough prestige before ascending the throne."

"Whether it's fame or merit, it can be counted."

"That kid has a loud abacus, and he knows that I will definitely not rashly move the five surnames and seven hopes before, so I only told you one person."

"But it's different now."

"They've touched my mold, and I'm not that easy to bully."

"What Lu Heng thinks, I also think."

"The book will be printed out and sent to various state capitals in Datang, and it will be distributed for free for a while."

"It's good to support the children of the poor family to become upstarts and wash the court of the Tang Dynasty!"

Li Chengqian was shocked.

He could hear what Li Shimin wanted to do.

What's so ......

Isn't it the same as Lu Heng's plan, using a large number of cheap books to support the children of the poor family?

It's just that His Majesty Li Er's methods have to be more ruthless!
