Datang: Stop pretending, you are a peerless expert

Li Shimin and the queen, holding their baby Li Lizhi, went to the Ministry of Industry.

Enter the Ministry of Industry, which is the high-tech center of Datang, where all the most advanced things of Datang are developed and manufactured.

Datang's Modao and the strongest crossbow were all invented here.

A group of skilled craftsmen are researching, and the iron furnace is burning with raging fire.

Eunuch Gao entered the Ministry of Industry and shouted: "The emperor is here!"

Officials from the Ministry of Industry hurried over to greet him.

"Xu Sheng, Minister of the Ministry of Industry, pay homage to my emperor, long live the emperor, thousand years old empress, and the princess."

Xu Sheng, the servant of the Ministry of Industry, is a gray-haired old man who is considered a senior technical talent in the Ministry of Industry.

"Xu Shilang get up, there is no need to be so polite."

Li Shimin laughed.

This Xu Sheng is usually diligent and conscientious, and Li Shimin respects him very much.

In particular, his technology is the best in the world, the most complicated iron smelting technology, quenching technology, the manufacture of crossbows, and the production of farm tools, Datang's technology is almost covered by him alone.

"Wei Chen dare not."

Xu Sheng is very humble.

When Li Lizhi arrived at the Ministry of Industry, she thought it was fun, so Mo Yu took her there to play.

"Xu Shilang, Qu Yuanli, which I brought back a few days ago, are you ready?"

the queen asked.

Xu Shilang quickly replied: "More than 5000 Quyuanli have been made. The Ministry of Industry now uses them to produce Quyuanli except for weapons. The design of this Quyuanli is really ingenious and exquisite. The old minister really admires it." The five bodies are cast on the ground, the empress has a wonderful idea, I can't wait."

When Xu Shilang saw Qu Yuanli and the design drawings, he was very shocked.

Zhiyuanli has been used for thousands of years, but he didn't expect to change it.

Especially myself, I have studied farm tools all my life, but I didn't come up with such a design.

"This isn't Bengong's design, it's a young master's. He built this Quyuanli, and it has been used in his village for several years."

said the Queen.

Xu Shilang was astonished, it has been used for several years.

"Not only is Qu Yuanli's design ingenious, but his design blueprints are even more ingenious. It's just that there are many things I can't understand."

Xu Sheng said.

"Can't understand? Xu Shilang has worked in the Ministry of Industry for most of his life, and there are still drawings that Xu Shilang can't understand?"

Li Shimin was surprised.

Most of the skilled craftsmen of Tang Dynasty, not to mention all, were designed or improved by Xu Shilang.

He has drawn countless design drawings, but there are some that he can't understand?
Xu Shilang took it out of his sleeve, spread it out, and pointed to the Pythagorean law, curvature calculation, Arabic numerals and triangular symbols cos and sin on it
"Your Majesty, what do these symbols mean? I don't understand."

Li Shimin was stunned: Damn, I've never seen it before!

The queen smiled and said: "I took a look at it when I brought it back, and I really don't understand it. I thought Xu Shilang could understand it, but I didn't expect that he couldn't understand it either."

Li Shimin asked: "Then Xu Shilang can't understand the design drawings, so how did he design and make Qu Yuanli?"

The tools are naturally designed according to the drawings. If you can't even understand the drawings, how can you make them?

Xu Shilang said embarrassingly: "I'm not afraid of the emperor's jokes, my minister is following the gourd painting, so I use the copy brought back by the empress."

This.
"Not bad, very good, as long as it can be made, is it useful?"

Li Shimin said.

"It works, works well, has been tested outside, and has been distributed to surrounding farmers for free."

Xu Shilang said.

In order to promote production, Li Shimin directly gave away production tools to farmers who could not afford them.

"Xu Shilang did a great job."

Li Shimin said.

Whether it is a horse or a donkey, as long as it can pull a mill, it will do.

"Your Majesty, Your Majesty!"

There was a sudden commotion outside the engineering department, Changsun Wuji ran in panting, he had a huge body and it took a lot of effort to run.

"Zhao Guogong, why are you so flustered?"

Li Shimin found it interesting to see him running like a big fat man.

"Brother, speak slowly if you have something to say, and be so anxious."

said the Queen.

"Youyou State"

Changsun Wuji couldn't speak, he was too anxious.

Li Shimin's heart skipped a beat when he heard the word Youzhou, and secretly called out that it was not good.

Du Ruhui, Shangshu of the Ministry of War, ran in and said, "Your Majesty, something is wrong, Luo Yi has turned his back!"

Li Shimin was dumbfounded when he heard that Luo Yi had turned his back on him.

Su Yu didn't joke, Luo Yi really turned his back?

The queen couldn't close her mouth in shock, and stood there in a daze.

"Reverse? Is he really rebellious?"

Li Shimin said repeatedly.

This made Changsun Wuji look confused: Is it really the opposite?Did the emperor know that Luo Yi was going to rebel?what's the situation?
"Your Majesty, Luo Yi has really turned his back."

Du Ruhui said.

Zhangsun Wuji was confused and jealous: All of you know about Luo Yi's plan to rebel, but I don't?Am I not the first minister of the court?Am I not your uncle?Actually hiding it from me?
"Back to the palace!"

Li Shimin returned to the imperial study in a hurry, and ordered the important ministers of the court to be called over.

Not long after, Fang Xuanling, Du Ruhui, Changsun Wuji, Yu Chigong, Cheng Yaojin, Qin Qiong, Li Jing, Li Shiji
Civil and military officials have all arrived.

Li Shimin sat on the dragon chair, full of thoughts.

The news of Luo Yi's rebellion had just arrived in Chang'an City, Cheng Yaojin didn't know what happened yet.

"Shubao, what's the matter? You called me over suddenly. I'm drinking at home."

Today Cheng Yaojin secretly took money from his own house to buy high-quality wine brewed by Su Yu. He was drinking happily, but he was announced to the palace.

The location is the Royal Study Room, Cheng Yaojin knew something important was going to happen.

The bigger things are, the fewer people know about them and the fewer people involved in making decisions.

This is the law of officialdom, big things, hold a meeting.

A few people have decided on a big matter, and you don't know it yet.

"Luo Yi is reversed."

Qin Qiong said in a low voice.

"What, old Luo Yi has gone wrong."

Cheng Yaojin shouted.

Li Shimin's thoughts were interrupted by Cheng Yaojin's words, he raised his head and looked at Fang Xuanling and Du Ruhui, the three of them had a tacit understanding.

Su Yu mentioned Luo Yi's rebellion three days ago.

However, the three of Li Shimin took Su Yu's words as a joke.

"My dear friends, you all know that Luo Yi has turned his back on you, please tell me what to do."

Li Shimin murmured in his heart: Su Yu said that Luo Yi died later, so there was no need to send troops.

Is this reliable or not?

In case it is wrong.
Ah bah, Su Yu didn't miss it.

What the hell, I didn't believe him at first, but now it's all come true.

Is this kid a fairy?
Luo Yi rebelled with his front foot, and he knew it with his back foot.

"Your Majesty, old Luo Yi failed the country's grace and killed him. I, Old Cheng, will take the lead."

Cheng Yaojin yelled.

The other generals did not speak.

At this time, Datang had just experienced a catastrophe, and it was necessary to guard against Turkic sneak attacks, especially Luo Yi's cavalry was elite. If he went south with all his strength, he could reach Chang'an City soon.

The most frightening thing is that if Luo Yi and Turkic Jieli collude and attack south together.

Li Shimin's scalp tingled when he thought about it.
