Li Shimin arranged for Li Junxian to send the slightly drunk Du Ruhui back to the house to recuperate, and he returned to the Cheng'en Palace.

Empress Changsun was talking with Li Liqing, and when she saw him come in, she was still holding some wooden boards in her hands, and she couldn't help but ask curiously, "What does Your Majesty hold?" ”

Li Shimin raised the wooden board and looked at it, and said with a smile: "Keming handed it to me, saying that it was offered by a student named Pei Xingjian in Hongwen Hall. ”

He has an impression of the name Pei Xingjian, and the last article about the reform of the imperial examination seems to have come from him.

And......

"Pei Xingjian?" Empress Eldest Sun thought for a moment, "But Pei Zhonggong's descendants?" ”

In the second year of Wude, Pei Xingjian's father Pei Renji failed to assassinate Wang Shichong, and then was killed, and was posthumously named the governor of Yuanzhou, and was given the nickname "Zhong".

Therefore, the eldest grandson queen called him Pei Zhonggong.

"What the queen said is true, and that's what I want to say." Li Shimin nodded and said: "After Pei Renji was killed, he still packed up his bones and buried him to repay his kindness, and said that he would be buried with him on Beibi Mountain after death.

Therefore......

After the murder of the Duke of Yan, I fulfilled his wish. ”

Li Lizhi next to her looked surprised when she heard this.

I didn't expect Luo Datou and that nerd Pei Xingjian to have this relationship, no wonder the relationship is so good.

What I didn't expect was that Pei Xingjian's father was still a loyal man.

Since then......

Don't bully him too much.

"Alas......" Li Shimin's side, every time he mentioned Luo Shixin, the Duke of Yanguo, he inevitably sighed.

Empress Eldest Sun was thoughtful, and deliberately diverted the topic: "Your Majesty hasn't said yet, what is this plank." ”

"Oh!" Li Shimin came back to his senses, "It is a kind of template called engraving printing......

Pei Xingjian also attached a note that it was created by one of his friends, but his name was not indicated. ”

"Luo Tai Sui!" Li Li didn't want to think about it, and blurted out.

"Luo Tai Sui? It should be that he is right! Li Shimin also thought of it.

Although her daughter has never mentioned Pei Xingjian, this strange man has appeared next to her, how could Li Shimin not find out?

So I also know the relationship between Pei Xingjian and Luo Taisui.

Empress Eldest Sun was also in the know, and chuckled: "I'm afraid that Luo Taisui, this kid, wants to help his friend, but his friend doesn't want to take the credit."

These two children ......"

"A talented person, a temperamental person, are all rare talents!" Li Shimin exclaimed.

Gathering it to its subordinates to cultivate it well can be regarded as another wealth left to the prince.

"And what is this object for?" Empress Eldest Sun asked.

Li Lizhi was also curious.

After all, Luo Taisui had never shown her this thing.

But what can be presented to the father is definitely not simple!

Good for you, you've learned to hide your secrets!

You wait for me!

She narrowed her eyes like a ruthless kitten.

Then she saw her father offering a treasure in front of her mother, smearing it on the board with ink, and then covering it with blank paper, and brushing it gently......

Something magical happened.

The originally blank paper was filled with dense text.

"It's ...... Rubbing? Empress Eldest Sun guessed, but then overturned her own conjecture, "Oh, it doesn't seem to be." ”

Rubbing is white on black, and this is black on white.

"It's block printing!" Li Shimin dragged the special name of this object in front of his wife and daughter.

"This kid ......," Empress Eldest Sun took the paper with the text printed on it and looked at it in Su's hand, "and the surname Zhao was ranked first." ”

Li Shimin and Li Lizhi leaned their heads over to look, it was really.

The surname Li of the royal family is only ranked fourth.

Uh-huh!

Doesn't that catch your little tail? Luo Datou!

Li Lizhi was a little proud.

"These surnames are arranged quite randomly, and I guess he didn't think too much about it."

For Luo Taisui, Li Shimin has an unusual tolerance, and muttered: "With this engraving printing, a large number of books and documents can be reproduced in a short period of time, and it is very practical." ”

"But the traditional families are not happy." Empress Eldest Sun seemed to mean something.

Li Shimin was slightly stunned, then reacted, stroked his palms and laughed: "Okay! Good! O Shixin! Your good boy, with any move, you will dig the root of the family! ”

Then, as if he couldn't get enough of it, he shouted a few more times.

Among the three people, Li Lizhi is still in the dark, and she doesn't understand that just these few broken planks have dug up the foundation of the family?

Seeing her daughter's blank face, Empress Changsun explained to her: "Take the current imperial examination as an example, in addition to the various privileges of the family, the most important thing is the leadership of family learning.

And the root of these family studies is the family's family collection of classics, because it is inconvenient to copy by hand, there is almost no need to worry about circulation.

But with this approach, the Maison's advantages may no longer exist.

Do you understand that? ”

"Erchen understood." Li Lizhi is talented and intelligent, so she naturally understands everything.

But......

Forget about the father and queen mother, that guy Luo Datou has such a vision, and it is really not the oil of the provincial lamp.

Next, the three of them chatted for a while around this engraving printing, and Li Shimin planned to hand over the "Hundred Family Names" to Gao Shilian and let him revise it together with the family list.

Then the technology of engraving printing should be studied by the Ministry of Industry, and it should not be difficult, and it can even be popularized.

The night was getting deeper, and Li Lizhi got up and retired.

"Xiao Changle."

At this time, Li Shimin stopped her.

"What's the matter with my father?" Li Lizhen stopped.

"Before, due to natural disasters, your marriage with the eldest grandson's family was delayed for a long time......," Li Shimin said while observing his daughter's reaction, "Now that everything is on the right track, I am thinking about giving this matter a decision in the near future."

What do you think? ”

"Your Majesty......" Empress Changsun wanted to speak and stopped.

On the one hand, he is his own nephew, and on the other hand, he is his own daughter.

She knew that her daughter was extremely reluctant.

This thing......

It's a dilemma.

It's finally here...... Li Li said secretly in her heart, but she was not in a hurry, and said calmly: "Why did my father say this? ”

Li Shimin saw that his daughter obviously wanted to repay the debt, so he put on a straight face and said: "Xiao Changle, the marriage of children has their own parents' orders, and the words of the matchmaker can't help you be willful!" ”

Li Lizhi didn't know that he was a paper tiger, and he still had nothing to fear.

"The order of the parents, the words of the matchmaker, no matter how great it is, can it be greater than the law of the Tang Dynasty?" She said unhurriedly.

"The Law of the Tang Dynasty?" Li Shimin was angry, "Which law in Datang prohibits parents from deciding on the marriage of their children?" ”

"I don't know here." Li Li said confidently: "But Erchen knows that there is a rule, no intermarriage is allowed within five suits!"

This was approved by my father and deliberately added to the laws of the Tang Dynasty! ”

"Me!"

Li Shimin was dumbfounded.

The eldest grandson's beautiful eyes moved back and forth between the father and daughter, and finally couldn't help but burst out laughing.
