Everyone shouted wildly, and Li Chengqian was depressed above.

What does it mean that His Royal Highness the Crown Prince has flown into the sky?

Is Lao Tzu good at flying?

He looked at the group of turtles below, did he know what a hot air balloon was? I really haven't seen the world before.

"Gao Ming, what are you doing here? Come down! ”

Li Shimin was a little displeased. As soon as he came, he did this, which made him a little unhappy.

And Li Chengqian slowly lowered the hot air balloon.

When he reached the ground, Li Chengqian got down from the hanging basket and tied the rope to the pillar.

Everyone gathered around and looked at the huge hot air balloon, and they all felt amazing.

Li Shimin was originally angry, but he was also attracted by this big thing.

It's so small when it's in the air, but once it's on the ground, it's a behemoth!

"Gao Ming, what is this? Why can you fly in the air? ”

He asked.

Li Chengqian said: "Your Majesty, this is a large hot air balloon!" As long as it is lit below, this thing can be lifted into the air! Just like Erchen just did. ”

People still don't know much about how this works.

So Li Chengqian said again: "This thing is based on Zhuge Liang's Kong Ming lantern during the Three Kingdoms period!" ”

When he said this, the people understood.

Although they don't know what the principle is, it is an indisputable fact that the Kong Ming lantern can indeed be lifted into the sky. Everyone also often puts Kong Ming lanterns.

But no one is going to carry it forward.

So everyone was shocked.

"I didn't expect His Royal Highness the Crown Prince to be able to draw inferences from one another, and use it like this, it's really a genius!"

"Yes, it's really a genius, we can't think of it, His Royal Highness the Crown Prince actually thought of it."

"To be able to sit on it, that's like climbing high and looking far away!"

……

These ministers talked to their heart's content, and at the same time, a large number of points also fell into Li Chengqian's pocket, but he didn't like these points because there were too few.

It would be a very coercive thing to fly in front of the masses of people with this huge hot air balloon.

People's flattery of people made Li Shimin very unhappy.

He glanced at Zheng Liwan, then at Li Chengqian, and said, "Gao Ming, this side of Xinjiang is tight, do you still have time to get these playthings here?" You must know that now our Datang grain and grass can't enter Liangzhou! Can't cross the river! Do you have time to play with this balloon here? Just to accompany this woman? Make them happy!? ”

Li Shimin pointed at Zheng Liwan.

The so-called red face and troubled water, Li Chengqian couldn't have imagined that after Zheng Liwan was seen by Li Shimin, this guy would have to say what he was doing everywhere.

Li Shimin thinks so much! Sometimes there are things that are obviously not in 6, and after he says this, it is like that!

In fact, he originally wanted to use a hot air balloon to curry favor with Zheng Liwan and Wu Zetian, and took them in the sky above Chang'an City to look at the beautiful scenery of Chang'an, what a pleasant thing it was.

Since Li Shimin is unhappy, then he naturally has a way.

After all, there are many examples of throwing hot air balloons into war, it's just a tool, it's up to you how you understand it.

So, he said, "Your Majesty, you have misunderstood your son. That's not the case with Erchen. ”

As soon as these words came out, Li Shimin was surprised.

"Okay, just tell me how I misunderstood you!? Didn't you build this hot air balloon for fun? I was so happy to see you. ”

Li Shimin was a little forceful, but Li Chengqian was unhurried.

"Definitely! Your Majesty, this balloon can be used to transport goods, and at the same time, it can be used to transport goods regardless of the environment, no matter how bad the environment. ”

Li Chengqian said, if this is the case, then this hot air balloon is indeed a big artifact.

Empress Changsun also saw that Li Shimin was very angry just now, and she didn't know how to persuade her, and now Li Chengqian has resolved the embarrassing crisis.

She also came out and said:

"Your Majesty, the concubine said, you must be wrong to blame Gao Ming. Gao Ming is worried about Datang all the time, how can he lose his mind with playthings? ”

Li Chengqian's heart was secretly refreshed, with the intercession of Empress Eldest Sun, Li Shimin not only would not scold himself, but might also reward himself.

And be flawless.

So he said:

"Yes, Your Majesty, Erchen heard earlier that after General Qin went to Liangzhou, he encountered the melting of ice and snow, and the sudden birth of a large river caused the materials to be unable to be transported, so Erchen has been studying hot air balloons in the East Palace for the past few days, and finally caused it when His Majesty came, and it was Your Majesty who was blessed."

Li Chengqian's words made Li Shimin very happy to listen to, he was happy, everything was much easier.

"It's your fault for saying that!"

Li Shimin said bluntly.

"Erchen is also at fault, and he failed to report to His Majesty in time, which caused His Majesty's misunderstanding."

Li Shimin laughed.

changed his face in an instant, and people said that accompanying the king is like accompanying the tiger, and they are talking about such Li Shimin.

"Look, look, you are an example for you to learn! Learn from him! ”

Originally, he was going to train Li Chengqian, but now it seems that he has become a training minister. The ministers must be depressed in their hearts, what did we do wrong?

Li Shimin is right to say anything, and Li Chengqian is also so-called, anyway, why can't he say that he is here.

Subsequently, Li Shimin said: "How high can this hot air balloon fly?" ”

"Your Majesty, the height of Sili is the highest, and the air will become thinner upward, which is not good for people's health."

That is, it can fly at an altitude of 2,000 meters. This height can be said to be like a cloud for ancient people.

As soon as these words came out, everyone was in an uproar.

Someone also said: "If you use it to fight, it will fly up to a height of four miles, and even the enemy will not be able to fight it!" ”

But it's so high, how to fight?

However, it can be used to distribute leaflets to confuse the enemy and disintegrate the enemy's internal forces.

"Yes, not only that, but if you raid the rear of the enemy army through a hot air balloon at night, it is the deadliest existence."

These ministers have finally played their part.

Li Chengqian smiled and said: "That's right, everyone is right, that's why this king wanted to invent the hot air balloon, however, it has a fatal flaw, that is, the problem of fuel, often can only fly for an hour at most, you have to refuel, otherwise the hot air balloon will run out of power and fall directly to the ground, which will be too dangerous." ”

If the power is unlimited, then it is called powerful, a hot air balloon travels all over the world.

Others can't, but Li Chengqian can, because he has a mall where he can exchange fuel at will.

Li Chengqian said in great detail, and Li Shimin was a little moved when he heard it.

"Hearing Gao Ming say that, I want to give it a try!"

As soon as these words came out, everyone fell silent.
