Following.

The wind was cold.

As for how to deal with the next harmony, Li Zhong feels that he can't just stay at the stage of thinking.

So......

He asked Li Er for two hundred copper coins, as well as a group of craftsmen who could forge copper bells and copper tripods.

Li Er was naturally puzzled: "What do you want so many copper coins for?" ”

The eldest grandson queen was also there, and the three of them chatted while walking.

Li Chong said, "I want to make something." ”

Li Er: "......"

Empress Eldest Sun: "......"

Then the two looked at Li Chong.

Wait for him to continue.

Li Zhong continued: "This thing can't be spoken. ”

Li Er: "......"

Empress Eldest Sun: "......"

After being speechless for a while, Empress Eldest Sun couldn't help but say, "You want to make something, but you don't tell Your Majesty, so how can Your Majesty give you the money?" ”

Li Chong glanced at Li Er.

Trust!

Li Er said, "Okay!" Isn't it two hundred? ”

Empress Eldest Sun: "......"

Two hundred guan is not a small amount, that is equivalent to six or seven hundred horses of silk, and you can't get enough silk, but copper, in the entire Tang Dynasty, is relatively small.

Otherwise......

I won't want to use silk as currency.

Li Chong then said: "It's okay if you don't give money, you can just give me bronze of the same weight." ”

Li Er was so indulgent to Li Chong that he agreed without hesitation.

Wait until after Li Chong leaves.

Empress Changsun couldn't help but ask Li Erdao: "Your Majesty, you really don't ask him what he is doing with so much copper?" ”

Li Er took a deep breath, "When he wants to say it, he will naturally say it." ”

Empress Eldest Sun also said calmly: "No wonder others say that Li Chong is His Majesty's male favorite." ”

Li Er: "......"

……

About ten days passed.

Got the copper.

Got the craftsman again.

The next step is for the craftsman to cast according to the drawings he has drawn.

This is naturally not a problem for Datang craftsmen with rich experience.

However, even so, if he wanted to get the bronze cannon he wanted, he had to go to Zhenguan for ten years.

Zhenguan ten years.

New Year's Day, Xin Chou.

Ashina Sheer came to surrender.

It's the one who fights with Xue Yantuo, loses every time, and has to fight if he loses.

Li Er can't be said to be unattached to Ashina Sheer.

As soon as he came up, he named the other party as the general of Zuo Xiaowei, and after that, he married the other party with the eldest princess of Nanyang.

It's weird.

For such a 'harmony', Li Chong will not hate it at all.

Because he knows that Ashina Sheer is the licking dog of the Tang Dynasty and is loyal.

And......

Next, Ashina Sheer will also settle in Chang'an.

I saw Li Zhong sigh, "But the cannon has already been made, and it will definitely be test-fired." ”

February.

Li Chong finally got the cannon made by the craftsman.

To be precise, it should be a gun carriage.

Because a cannon weighs thousands of pounds, ordinary people can't move it at all.

When it is made into a gun truck, I think it is much easier to carry.

Li Zhong checked the quality and felt okay.

But how do you try it so that you don't let people see it?

The point is, he also needs a gunner.

Of course, it is impossible for a person like him to go to the battlefield to take risks.

That's not what a colt should do.

The only way to do that is to find someone you can trust.

……

Princess's House.

While drinking wine, Li Chunfeng told Li Zhong about the data he had measured in the past two years and some new discoveries.

Li Zhong also listened carefully.

From Li Chunfeng's mouth, Li Chongneng felt his love for astronomy, but Li Chongneng was the only one who could be trusted.

Li Chunfeng is a typical science and engineering thinking talent, although in the history books, he is generally compared with Yuan Tiangang.

But Yuan Tiangang is actually more inclined to those traditional people's impressions of the gods.

"Master Li, you don't know ......?"

Listening to Li Chunfeng talk eloquently.

Li Chong still couldn't open his mouth after all.

After all, he loved astronomy so much.

If you let him be an artilleryman now, it won't be too cruel to the other party.

can only echo: "I said a long time ago, the earth is a circle!" Now, your observations can be regarded as indirect proof of this. ”

"But how do you know?"

Li Chunfeng asked.

"I was born smart. By the way, have you ever thought about changing your official position? ”

In order to interrupt Li Chunfeng's search for the roots, he unconsciously asked.

Li Chunfeng said, "What do you mean?" ”

Li replied: "I think it's too condescending for you to stay in the Taishi Bureau. ”

Li Chunfeng: "? ”

Li Chong: "I want you to do things for me." ”

Li Chunfeng: "......"

Li Chong: "Ahem! Of course, it's not a bad thing, it's a serious thing. For Datang, it should be said that it is still a little helpful. I just think it's useless for you to stay in the Taishi Bureau. You can't predict the weather for the next seven days. ”

Li Chunfeng looked inexplicable and replied, "Why seven days?" ”

LI Chong; "It doesn't matter! I want you to be the vice president of the Academy of Sciences, what do you think? ”

Li Chunfeng: "......"

Li Chunfeng was silent.

Li Chong said: "You look down on the Academy of Sciences." ”

Li Chunfeng: "No. I'm just a little curious, and, a little bit confused. I'm not a craftsman, and even if I go to the Academy of Sciences, it's useless to you, Master Li. ”

Li Chong poured wine for Li Chunfeng and said: "Don't be presumptuous, smart people, no matter where they go, they can give full play to their ingenuity." The key is whether you are willing to go or not. I don't know anyone in Datang, and the only one I can trust is you. After all, I can't let Sun Simiao be the vice president of the Academy of Sciences, right? Moreover, Sun Simiao is also very busy, he has been writing medical books recently, and he has to treat people. ”

Li Chunfeng: "Speaking of which...... It's been a long time since I've seen Doctor Sun. I'll have to visit another day. ”

Li Chong: "Back to business, I want you to be the vice president of the Academy of Sciences, and you should not be." ”

Li Chunfeng hesitated: "Is it okay to work part-time?" ”

Li thought about it for a while: "It's okay." ”

Anyway, if you go out, you will be artillery, and if you enter, you will be the general of the Taishi Bureau, which is also very good.

Of course! There are some things that Li Chong had to say in advance.

Li Chong: "Next, everything you see at the Academy of Sciences must be kept secret. You can't mention it to anyone else, not even your parents, wife and children. Speaking of which...... Do you have a son? ”

Li Chunfeng said: "This is naturally there, I am seven years old this year." ”

Li Chong said: "That's not a big difference, let's mix with my son." ”

Li Chunfeng: "Huh? ”

Look at Li Chong's appearance of wanting to make a big move.

Li Chunfeng also couldn't help asking, "Master Li, do you have any big things to do?" I won't do this against Tang Law. ”

Li Chong smiled, "Where do you think of it, I'm not the kind of person who violates the law and discipline." I just love Datang deeply. ”
