Two days later, the injury on Li Zhi's buttocks finally healed.

When he came to the Taiji Hall in a strange posture, Li Shimin raised his head and gave him a blank look, and then lowered his head and continued to read the folds.

After Li Zhi saw his Lao Tzu's attitude, he knew that he was waiting for him to say a few good words and coax.

So he came to Li Shimin's side very doggedly and squatted down, and helped Li Shimin beat his thighs very rhythmically with his two hands.

I only heard him speak: "Father, the son already knows that he is wrong, so don't be angry with the son again."

If it is because of the recklessness of the recklessness of the sons, the body is broken, wouldn't it be detrimental to the prestige of the Heavenly Khan? ”

Li Shimin's legs are actually not tired, but he enjoys Li Zhi's massage very much.

So he made his body more relaxed and said, "You still know that you are reckless?

Do you know if you will be angry with your body when you consider being a father? ”

Li Zhi smiled "hehe" and said: "This matter is indeed ill-conceived by Erchen.

Now that the sons have known their mistakes, the father and the emperor will stop worrying with the sons and daughters for the sake of the sons and daughters. ”

After listening to Li Zhi's words, Li Shimin "hummed" and said: "You don't talk about your age in front of your father."

In my opinion, I am not as bold as you alone in adding up so many civil ministers and military generals in the court.

Even in these dynasties, no one has dared to run to the sky like you. ”

After listening to Li Shimin's words, Li Zhi laughed and said, "Father, I am angry.

Erchen, this is also contributing to my Datang's scientific and technological career! ”

Li Shimin lowered his head and glared at Li Zhi and said, "There are so many people in the academy, so no one can do this anymore except you?" ”

Li Zhi said: "After all, it is Erchen who came up with it himself, of course, it is better for Erchen to operate it himself." ”

After Li Shimin listened to Li Zhi's words, he kicked him lightly, signaling him to beat the other leg.

It wasn't until Li Zhi turned to the other side that Li Shimin spoke: "According to me, it seems that you just don't know the severity.

That's tens of thousands of feet in the air, and you dare to go up directly without verifying it?

Haven't you ever thought about how sad your father and your mother would be if something happened to you?

Do you know that your imperial grandfather almost fainted directly after hearing about this?

If he is frightened out of what you have done, he will not be angry if he picks your skin for the father. ”

After hearing this, Li Zhi also felt scared for a while.

He is well aware of the dangers of hot air balloons.

In terms of Datang's current technology and material technology, the probability of accidents is really not low.

When he decided to fly up, he didn't think about the consequences of failure.

Now that I think about it, I was a bit careless.

Thinking of this, Li Zhi didn't defend anymore, but honestly spoke again: "Erchen knows that he is wrong. ”

Li Shimin sighed after listening to Li Zhi's words.

He gently patted Li Zhi's shoulder and said, "It's good to know your mistakes, don't be so hasty in doing things in the future!" ”

Li Zhi nodded wordlessly.

Li Shimin continued to speak: "You said that this hot air balloon is very useful back then, and today you are just going to talk to your father in detail. ”

Li Zhi said: "At the moment, this hot air balloon is only in its primary form.

All you can do is reconnaissance on the battlefield, transmit information, and if you are proficient, you can also use it to drop explosives to attack the enemy.

In the future, when the technology matures, it can also be used for topographic survey, weather prediction and astronomical observation.

Of course, if the technology is mature, it can be used for long-distance transportation. ”

After listening to Li Zhi's words, Li Shimin immediately became interested in hot air balloons.

Leaving aside the other functions for the time being, the fact that it can be used in war alone is already attractive enough for Li Shimin.

So he asked, "How safe is this thing?" If you have a lot of equipment, you can get serious casualties? ”

Li Zhi said: "As long as the material is reliable, the safety is still very guaranteed.

It's just that this thing is too dependent on the weather conditions to handle, so it's not very useful. ”

Li Shimin said, "What do you know? It is difficult to maneuver, but it is not limited by terrain.

The difficulty of my Datang fighting with the surrounding countries is how to quickly get to the enemy's location.

If it is safe, it can be used as a means of transporting troops.

At that time, if our Tang army can suddenly appear in the enemy camp, won't the other party let us handle it at will? ”

After listening to Li Shimin's words, Li Zhi immediately reacted.

In the previous life, when the hot air balloon was invented, countries around the world already had planes capable of attacking hot air balloons.

At that time, the role of hot air balloons was naturally limited.

However, in this day and age, it is completely different.

Hot air balloons are not only not attacked by enemies on the battlefield, but can also be used as troop carriers.

If you add the reconnaissance and attack capabilities, this hot air balloon can be regarded as invincible.

So he hurriedly opened his mouth and encouraged Li Shimin: "Father, Erchen has set the subsequent development direction of the hot air balloon.

Why don't you find someone to study it specifically, so that my Datang army can dominate the world without using war horses? ”

After hearing this, Li Shimin nodded excitedly and said, "That's how it should be, it's how it should be!" ”

After listening to Li Shimin's words, Li Zhi continued: "This thing is also of great use to Qin Tianjian.

Why don't you let Li Chunfeng and Yuan Tiangang participate together, so that my Datang can reach a new level in astronomy and meteorology? ”

Li Shimin nodded and said, "Okay, then according to your opinion, hurry up and arrange manpower to conduct research." ”

Li Zhi nodded and continued to speak: "Father."

Now although Tubo has surrendered to my Tang Dynasty, the strength of Tubo cannot be underestimated after all.

Bailan, the party item Zhuqiang has been included in the territory of our Tang Dynasty, which makes the border between the two countries a little long.

Erchen suggested that the Western Regions Protectorate be placed on the border between the two countries, and by the way, the dragoon army should be transferred to the territory of Gaochang.

In this way, it can not only protect the safety of Zhuqiang, but also prevent sudden accidents in the Western Turks. ”

Li Shimin listened to Li Zhi's words and said with a serious voice: "Have you listened to the rumors of those ministers? ”

Li Zhi shook his head and said, "Father and Emperor have misunderstood, Erchen has never worried that the dragoon army will lose control.

I believe that my father will not doubt the loyalty of his sons.

What's more, now that I, Datang, have developed a rifle, the combat power of the Dragoon Army is no longer unattainable in front of the Datang Army.

All Erchen thinks about is how to protect the thousands of miles of rivers and mountains of my Tang Dynasty with the least number of troops.

As for the words of those ministers, in the eyes of the ministers, they were nothing more than the chirping of mosquitoes and flies.

They were just afraid that their father, with such a powerful army, would kill them at any time. ”

After listening to Li Zhi's words, Li Shimin patted Li Zhi's head with a smile and said, "Don't talk nonsense. ”
