Datang: Acting as a celestial mystery at the beginning

The East Palace is where Prince Li Chengqian lives. He suddenly heard that the East Palace was on fire, and Li Shimin's heart was about to jump out. When he brought a group of guards to the East Palace, he saw that the fire had already been extinguished.

Fortunately, the fire was not big, and only burned a house, but in front of the house, there were still a pile of canvas and baskets left over from the fire, exuding a faint smell of kerosene, and there was still a pool of blood on the ground, but there were no injured people.

Li Chengqian stood in front of the pile of things, his immature face was full of solemnity, as if there was something he couldn't understand.

Li Lizhi was also there, hiding behind a palace lady, her face turned pale from fright.

There was also an old man and a group of guards standing beside them, all very nervous.

"What happened?"

Li Shimin hurriedly asked: "Chengqian Li asked, are you all right?"

Li Lizhi ran over quickly, held Li Shimin's hand, and said softly, "We are fine, only one guard was injured and was taken away."

"What's the matter?"

Li Shimin was very anxious, could it be that an assassin failed to assassinate him, and wanted to attack Li Chengqian instead.

"Your Majesty, this fire was caused by His Highness the Crown Prince. What kind of hot air balloon is he doing, and he almost burned the East Palace."

The old man's name is Kong Yingda, and he was also one of the 30 scholars of the Qin Palace, the No. [-] first grandson of Confucius, and served as the prince and grand teacher, and the post of Zhan Shi in the East Palace Zhan Shifu.

After Li Shimin moved out from the East Palace and lived in Taiji Palace, Li Chengqian was in charge of this place, and Zhan Shifu began to be built.

Because the crown prince is the crown prince and the future emperor, the official organization of the East Palace is basically established in imitation of the three provinces and six ministries, but the scale and number of officials have been reduced in order to familiarize themselves with how to govern the country in advance.

Zhan Shifu is equivalent to Shangshu Province, and the left and right Chunfang imitate Zhongshu Province and Menxia Province respectively.

The East Palace even has a ten-lead mansion, which was set up on the model of the Sixteen Guards. In the early Tang Dynasty, the ten-lead mansion in the East Palace had military power.

This is also the reason why the prince rebelled so easily in history. There is a small court in the East Palace, and the prince can still control the military power. If he is not satisfied, he can directly rebel and enter the Taiji Palace.

When Li Shimin heard that the crown prince made it, he immediately said angrily: "Li Chengqian, what are you doing?"

"Your Majesty, it's not His Highness's fault, it's Li Yi'an!"

Kong Yingda immediately said: "Li Yi'an doesn't know what air density to teach the prince. Now he can't even read the sage's classics, and he doesn't listen to his persuasion. These days, he has been asking people to make some hot air balloons, saying that they use kerosene to burn them. It can take people into the sky, and this fire comes from the kerosene of the hot air balloon.”

Hearing that it was knowledge from Mr. Li Shimin, he immediately lost his temper. Usually he doesn’t ask about it. What Li Chengqian learned from Mr., but within a month, there will occasionally be one or two discussions on government affairs and political theory. What did Li Chengqian learn.

What Li Chengqian has learned about politics has to surpass the highest level of this era, and it is completely no problem to respond to it, and it is straightforward.

Even in terms of governing the country and appeasing the people, the measures given were very good, which made Li Shimin feel relieved to hand him over to his husband.

He didn't pay attention to these things for a while, Li Chengqian actually made such a serious matter for him, and it had something to do with his husband.

"Li Chengqian!"

Seeing that he hadn't responded yet, Li Shimin yelled again.

"The firepower is not enough to be unstable. It must be like this. Can you make something to control the flame, adjust the size, and increase the fire at any time."

Li Chengqian was shocked, and accidentally said what he was thinking.

"You are talking to yourself, what are you talking about?"

Li Shimin said with a gloomy face, "What is this hot air balloon you got?"

Only then did Li Chengqian come to his senses. Seeing that it was Li Shimin coming, he hurriedly said: "A thing similar to a Kongming lantern, as long as the hot air balloon is big enough, it can carry people into the sky."

Kong Yingda first yelled: "Nonsense, how can a person fly into the sky, that is a fairy."

Li Chengqian reasoned and said: "Of course, this hot air balloon is the same as the Kongming lantern. Master Kong, do you know how the Kongming lantern flew into the sky?"

Kong Yingda was reading the books of sages and sages, so he didn't know this, so he shook his head and said, "I don't understand that lowly stuff."

In the eyes of their scholars, artisans, like businessmen, are people at the bottom of society.

"It's not cheap stuff, it's science!"

Li Chengqian said firmly: "According to what Mr. said in the physics class, the air around us is also dense. Use a torch to heat the air, and the air will expand, so that the density inside the balloon is lower than the density of the air outside the balloon, and you can fly up. As long as the density is high enough, it is not a problem to take people into the sky."

"What nonsense!"

Kong Yingda had never heard of such ridiculous remarks, and when he heard that he dared to refute his own words, his face flushed with anger.

"Aye, actually brother is not talking nonsense."

Li Lizhi said in a milky voice: "Brother's hot air balloon just now really brought a guard into the sky, but it was not flying very high and the wind blew, hit the top of the room, and fell off. That guard was so miserable. There was a lot of blood."

They suddenly realized that this is how the fire came.

"These are the master's knowledge, which is science. The master not only taught us physics, but also chemistry and mathematics. All of them are very useful, but you don't understand."

Li Chengqian insisted on his own ideas.

"Your Majesty, look!"

Kong Yingda grieved and said: "Your Highness followed Li Yi'an and learned so many lowly things. What should I do if you talk about science? The crown prince is the prince, and the future monarch. Is it possible that we will use these to govern the country in the future?"

"Li Yi'an is a man of bad conduct. He was so angry with Deming because of his personal affairs before. He doesn't understand the important affairs of his family and country. He will only mislead the prince and let him continue. There will be endless troubles."

He reasoned and shouted: "Your Majesty, please don't send the prince to Li Yi'an to teach."

After all, Kong Yingda bowed and bowed, very sure.

"Your Majesty, I think that the things that Mr. taught are somewhat inappropriate."

Du Ruhui couldn't see it either.

Hearing Du Ruhui's objection, Li Shimin had to start thinking, Mr. is indeed omnipotent, and what he gave was really novel, and even subverted some of their ideas.

But these things cannot assist Li Chengqian in governing the world in the future.

"I will think about it carefully!"

Li Shimin said lightly.

"Aye, you can't do this!"

Li Chengqian is not willing.

"To shut up!"

Li Shimin's face turned cold, making him afraid to say anything.

"Can I still go to play with my husband in the future?"

Li Lizhi said pitifully.

"Let's talk about it later!"

Li Shimin waved his hand and said: "Come here, show me the prince, if he dares to do these things again, come and tell me right away."

Li Chengqian looked frustrated.

This matter was put aside, and when he returned to Ganlu Hall, Li Shimin saw that the eldest grandson Wuji had just arrived, and hurriedly said: "Your Majesty, I have compiled the list of scholars for the palace examination tomorrow, please have a look at it."

Li Shimin thought of the imperial examination process, which was perfected by Li Yi'an on the basis of the former Sui Dynasty. Looking at the map on the case, he sighed: "If you only teach the strategy of governing the country, you don't have to worry me."
