Li Er stared at Li Chong deadly, this person wanted his beauty all day long, and he felt that the other party was not well-intentioned.

Seeing that Li Er was angry, Li Chong didn't say anything.

Seeing that Li Er didn't speak, Li Chong said goodbye.

Just now, I felt that Li Chong was not at ease, but after seeing Li Chong leave without hesitation, I felt a little reluctant.

"Queen!"

Li Er said directly.

Of course, he definitely didn't call Li Chong, he was talking about the queen's illness.

Only then did Li Chong stop.

Feel......

The timing is right, so he said: "We must pay attention to two points, first, where you usually live, you should live there as much as possible, so as not to adapt to all changes, and second, Your Majesty had better be able to control it." ”

After Li Zhong left, Li Er thought to himself, what does it mean to be temperate?

Back to the Academy of Sciences.

The stove was set up, and the sand was mixed with what was obtained from the salt pond and burned it with a try.

Outcome......

This thing didn't melt for half a day, there was melting, but not much.

Li Zhong knew that this should be something missing.

It should be a flux.

But what exactly to use as a flux, this Li Chong is not very clear, anyway......

Just let people go outside, and when they see stones, they bring some back, and try little by little.

As long as you try dozens of more kinds, there will be one after all, and it should work.

That's probably a month later.

Seeing that the sand was finally melting little by little, to be honest, Li Chong felt that it was not very difficult.

In fact, it's right to think about it, if it's too difficult, how could the ancients be able to burn it.

It is the purity of this raw material that needs to be selected again.

Because he wants as close as possible to transparent glass, not colorful ones.

Anyway, he knew that iron and copper would definitely not be available.

Then, he locked on calcium, for example, pure quicklime is good.

When the transparent glass water was finally boiled out, it could only be said that Rao was a member of the Academy of Sciences, and they couldn't help but be a little excited.

It's definitely not because it's worth a lot.

Rather, it's the kind of rewarding satisfaction that comes after a major study has been completed.

That's what they're after!

And at the same time......

After almost two years of field practice.

Li Chong's threshing machine and Quyuan plough have also been well received.

In fact, the north does not need the curved plough very much, but the south needs this very much.

It's just that there are still very few people in the south now, and they are far from being able to compare with the north.

Simply, Li Chong also took these three things to see Li Er.

How good it is, Li Chong doesn't want to explain anymore.

Directly gave Li Er a bunch of people's opinion feedback forms, of course, written by people from the Academy of Sciences, which can directly show how good this thing is.

In the past, when wheat was beaten from the wheat stalks, it hurt my back and back, but now I use my hands and feet together, and it is fast and good.

Even......

If every household could have such a threshing machine, it is estimated that the proper term threshing floor would disappear from the word of mouth of the people.

Because there is no need at all.

And the curved plow, the effect is also good.

In the comparative experiment with the straight plow, fifty groups of experiments, fifty groups all felt that the curved plow was better, more flexible than the straight plow, and more convenient to use, originally only one acre, now one and a half acres, it seems that there is still still room for power.

With these evaluations, Li Chong has a lot more confidence.

Li Er finished reading Li Chong's data, and passed it on to Fang Xuanling and the eldest grandson Wuji to see.

Then he sighed and said: "It's a pity that Du Ruhui is not there." Come on, send a copy of this copy to Du Ruhui's house, so that he doesn't have to worry about it and recuperates well. Other...... Over the years, Du Ruhui has been diligent and conscientious, and it is because of this that he fell ill, he is already a national prince, so he will not be sealed, and his second son Du He will be named the county man of Xinfeng County, and at the same time enter the East Palace, study with the prince, so that he has no worries. ”

Eldest grandson Wuji: "......"

Fang Xuanling: "......"

Wei Zheng, who was on the side, couldn't stand it anymore, and said, "Your Majesty, are you too casual to be knighted recently?" ”

glanced at Li Chong, forget this.

Why is Du Ruhui's son Du He like this now.

Does this Duhe make any contribution to Datang?

Li Chongye said: "Your Majesty, please consider carefully. ”

"What, Li Chong, you want to stop me too?"

Li Chong said: "If you want to seal Du He as the county man of Xinfeng County, I won't stop it, and if you seal Lantian County, I won't say a word, but when you enter the East Palace, I oppose it." ”

The atmosphere is a bit subtle.

None of the three could understand it.

But thinking about Li Chong, he is the prince and the prince, and he does have some say in the prince's education.

I think it makes sense.

And Li Er was also thinking about why Li Chong would stop it.

Not......

Maybe Li Chong is unwilling to teach?

He didn't say let Li Chong teach Du He.

He just asked Du He to accompany the prince to study.

However, it seems that this accompaniment does infringe on a little bit of Li Chong's terms of reference.

Forget it, Li Er quickly compromised and said: "Then the male of Xinfeng County will keep it, and I will talk about it later when he enters the East Palace to accompany the prince to study." ”

In fact, Du He is not very old now, and he should be almost the same as Li Chengqian, otherwise, Princess Chengyang will get his turn, and it can only be said that these founding heroes of the Tang Dynasty generally give birth very late.

However, at this young age, he was directly knighted, which is really good for Du Ruhan's family.

Since Du Ruhui is going to leave him, Li Er can only use this method to let him rest in peace as much as possible before Du Ruhui dies.

The will soon reached Du Ruhui's house.

Seeing the threshing machine, seeing the Quyuan plow, and then seeing His Majesty's concern for himself in his heart, and knighting his young son, Du Ruhui was also grateful.

It's a pity that you can't enter the East Palace.

Li Er asked Li Chong the reason afterwards.

Li Chong said: "It was this Du He who instigated Li Chengqian's rebellion. ”

Only then did Li Er understand.

As soon as Du Ruhui dies, the entire Du family will definitely decline.

A child like Du He, if he wants to restore the glory of the family, he can only take risks.

"So you're worried that he'll make the prince rebel again?"

Li Er asked.

I saw Li Chong shake his head and replied, "No, I'm not worried about this. I can't stand that there are such pig teammates around the prince. Even if he succeeds in his rebellion, no one will obey the prince. I like to be around smart people. ”

“……”

Li Er had nothing to say.

"Tiger father and dog, that's what you said, in fact, Fang Xuanling is too. Cough! Including Your Majesty, you too. ”

Li Er: "Then your son is very good?" ”

Li Er was very dissatisfied.

Li Chong said, "My son...... To be honest, I don't know what to do. I'm a person who only cares about my own happiness, so I don't really want to pay attention to them, and when the time comes, when I grow up, I will just lose the country. ”
