When the hot air balloon was inflated, it had already alarmed Li Shimin.

It should be said that the entire palace was shaken.

There was a sudden appearance of such a colorful ball in the East Palace, who could not see it, and it was not blind.

Even Li Yuan, who had not been doing anything for a long time, asked.

At this time, it was the time when Li Yuan, the emperor, was the most decadent, did he know Li Chuan? Know! Do you know that he came after a thousand years? Of course you do! But what does this have to do with him?

He is already too emperor, and he can't control being the emperor's son, he knows that no matter how much he can't do anything, that's it, why bother doing that?!

But today's show really made him curious, and at the same time a little unhappy.

Tossing around in his palace doesn't know how to say hello first? Scare him, the emperor, can he afford it?!

"Let's go, go to the East Palace." Li Yuan stared at the balloon for a long time and decided to go to the scene.

Li Shimin was relatively close, and he had already arrived at this time.

As soon as he entered Yiqiu Palace, Li Shimin saw his brother and his son, taking his brother's son to work hard to tie sandbags to a big basket, and the dangling big ball looked much more stable.

Remembering the scene of seeing the big ball ascend to the sky just now, Li Shimin pressed his heart that was beating fast.

"See Your Majesty." And all the people put down their work and came to pay their respects.

Li Shimin took a deep breath, calmed down his emotions, and his eyes fell on Li Chuan, "Tell me, what are you tossing about?" ”

"Tossing...... Heaven? Li Chuan scratched his head, didn't he suddenly get inspiration, so he planned to make a hot air balloon, anyway, he didn't expect it to go so smoothly.

Li Shimin has a black line, can he be reliable? Heaven? Do you really think he's an immortal?!

This thought had just flashed through him, and he remembered the big rickety ball that the wind had just seen, so, heavens, maybe it could really be, right?!

After only a moment of hesitation, Li Shimin missed the opportunity to taunt Li Chuan, and then, he also avoided being slapped in the face.

"Father, father, come and see, this large Kong Ming lantern, it can really fly." The little prince was so excited that he didn't want to, he dared to start and drag Li Shimin forward.

Li Shimin didn't care about this, his eyes were fixed on the colorful ball, the big Kong Ming lantern? It's not, looking at it like this, it's really an enlarged Kong Ming lantern.

This makes Li Shimin feel uncomfortable, how many years have Kong Ming lanterns appeared, many people are putting Kong Ming lanterns to pray for blessings every year, why didn't anyone think of making Kong Ming lanterns bigger?

Why? Why exactly? Following movable type printing, horseshoes, and more Kong Ming lanterns, are lit up and feel very simple, but before the window paper is pierced, no one can think of it.

"Why?" If you can't figure it out, ask Li Chuan, this kid must know.

Li Chuan looked confused, what is why? Why can hot air balloons fly?

"This, the hot air is rising, after the air is heated, it is lighter than the cold air, so it will float up, when we hold this part of the hot air, the force of the hot air will rise with us, as long as it is well controlled, we can swim in the sky at will, of course, there is also a risk that it will fall, so we need to be cautious when taking off." Li Chuan didn't know if Li Shimin could understand this explanation, he only hoped that His Majesty Li Er wouldn't impulsively ride a hot air balloon to the sky.

"Air?" Li Shimin is very unfamiliar with this term, but he can roughly understand what it means.

He really didn't pay attention to this phenomenon, but after Li Chuan said it, if he thought about it carefully, it was really like this.

When you light a fire in winter, the heat rises, and even the breath you exhale rises.

Li Chuan opened his mouth and didn't explain, he felt that even if he explained, Li Shimin might not be able to understand, and it was more likely that after he explained, Li Shimin would have more doubts.

For his own good, let's live silence.

"The Emperor has arrived!"

Hulala, everyone immediately ran over to salute.

Li Chuan is the last of these people, anyway, his title is the smallest, and it is just right to hide behind.

Actually, it's not hiding behind, because there are people behind him, that is, guards and craftsmen.

So to be precise, he's caught in the middle.

Li Chuan went out to take a peek, and the sight was a white fat man, who looked like he was about fifty years old, quite white, but there were a lot of wrinkles on his face, and it could be seen that the maintenance was okay, but the lifestyle was definitely not very healthy.

As for the majesty of being an emperor and the spirit of the king, he didn't see it at all.

There are too many people like this in modern society, and they won't look at it more than they walk on the road.

Li Yuan waved his hand, signaled everyone to be exempt, then stared at the hot air balloon, looked at it for a long time, and asked, "What is this?" ”

"Large Kong Ming lanterns." Li Shimin replied, walked over and helped Li Yuan to approach the hot air balloon, so that he could see more carefully.

"What are you doing with this stuff?" Li Yuan frowned, do you pray for blessings? Now is not the day to pray for blessings.

"Try to fly into the sky." Li Shimin looked up at the hot air balloon that was shaking a little again, and felt a little emotion in his heart.

The ancients had a lot of imagination about flying, but no one could do it.

As for him, since he watched the video from Li Chuan last time, he has been very greedy for those weapons, especially the plane, watching the iron guy pass through the air, his mood has also fluctuated.

But Li Shimin knew that that thing was not something that Datang could have, for Datang, airplanes, artillery and rockets were all invisible buildings in the air, unsightly and unreachable.

Unexpectedly, Li Chuan would be able to make a large Kong Ming lantern, this thing looks very simple, but it can fly if it can't stand it.

"Nonsense!" Li Yuan's face was blank, and he reprimanded: "What if such a big thing flies into the sky and falls and hits someone." ”

Li Shimin lowered his head and remained silent, and his attitude of admitting his mistakes was quite good.

He knew that his father was using the topic to play, just to get angry, so let him train him, anyway, just don't mix with the government.

Li Chuan silently took two steps back, pretending to be a pillar.

He is not afraid of Li Shimin, because he knows that His Majesty Li Er will use him, but Li Yuan is different, he was forced to abdicate and become the emperor, he can't manage political affairs, he can only hold it in the palace, just like a brazier that burns all the time, and it explodes when he adds some gunpowder.

"Collect the things, don't mess around, there are so many people in the capital, this thing flying out will cause casualties." Li Yuan was still unhappy in his heart, he trained, this emperor's son listened obediently, but the problem was that he only listened, and it was over after listening.

Whatever he says is in vain!

"The retainers will pay attention." Li Shimin replied.

Put it away? Definitely not, he still wants to test it, if he can, he also wants to go to heaven!
