"Hahaha, great! That's great! I've finally made it! ”

"Father, I made it! I made it! ”

Li Tai's hands danced excitedly, like a nervous disorder, yelling and screaming there.

Since Li Shimin's family was driven out of Chang'an, they came to Taiyuan, Shanxi, which was their former base and the place where they raised their troops.

Li Shimin's ambition is not dead, he is ready to make a comeback in Taiyuan, but before he thinks of a way to crack the Qintian hot air balloon, he can only accumulate strength.

And after Li Tai saw Qin Tian's hot air balloon last time, he kept the structure inside firmly in mind, and after coming to Taiyuan, he locked himself in his room and began to study it.

After many repeated experiments, it still didn't work, and he just didn't understand how Qin Tian managed to bring people to the sky.

In order to study how to carry people to the sky, he became crazy and couldn't sleep at night.

Finally, just today, Li Tai has finally figured out how to bring people to heaven, so it is no wonder that he will be like this, just like the expression of an expert who invents an important achievement.

"King Wei isn't sick, is he? I've been locking myself in my room, nervous! A soldier saw Li Tai as if he was stunned, and asked the people around him.

"Be quiet, and speak less, lest there be no good fruit to eat." Another warned.

"Father, come here, come on, I know, I finally know." Li Tai saw Li Shimin's figure, so he yelled loudly.

Li Shimin saw that Li Tai had no royal demeanor at all at this time, and frowned secretly.

"What is it that makes you so flustered?"

"Father, good news, great news!" Li Tai completely ignored the anger in Li Shimin's words at this time.

"What's the good news?" As soon as Li Shimin heard the good news, he also became energetic.

"Father, I know how Qin Tian brought people to the sky, I have already made it!" Li Tai's face flushed with excitement.

"What? Do you make it? Li Shimin was taken aback when he heard this, and he even pulled Li Tai to confirm without any image.

"Yes, that's right, Father, I've already made it!" Li Tai nodded in confirmation and replied.

"Quick, Qingque, take me to see it!" Li Shimin is now extremely excited, once he also masters this artifact, he will have a chance to recapture Chang'an.

"Yes, Father, please come with me!" Li Tai took Li Shimin to his room.

"Come here, get this one out there." Li Tai commanded the soldier who had just spoken.

The two of them carried the hot air balloon made by Li Tai into the courtyard, and at this time, Li Tai began to assemble it, and it installed a brazier in the hanging basket with some charcoal in it. After everything was done, Li Tai lit the charcoal in the brazier directly, and suddenly the airbag puffed up, and the hanging basket had slowly left the ground and went up.

Li Shimin was almost dumbfounded, and he really flew up.

However, Li Tai did not stop, and continued to throw charcoal into the brazier, and the fire in the basin also became larger, and the hot air balloon quickly took off.

In a few moments, the hot air balloon was about 10 meters above the ground.

Li Tai waved his hand at Li Shimin from above, and shouted loudly: "Father, I flew into the sky, hahaha......"

Li Tai's movement on this side attracted the attention of many people.

Soon, there were many more people around Li Shimin.

The eldest grandson Wuji was startled at first when he saw the hot air balloon, thinking that Qin Tian was calling, but it turned out that it was not, it was Li Tai on it, which shocked him, but he didn't expect Li Tai to make this kind of artifact.

"Your Majesty, this ......"

Seeing that it was almost over, Li Tai began to descend until he stopped steadily on the ground, and when he saw everyone's surprised looks, he was proud for a while.

Li Shimin patted Li Tai on the shoulder: "Qingque, you did a good job, you did a good job!" ”

"Father, this is what the son should do!" Although Li Tai said modestly, his heart was happy.

"Your Majesty, now that we have this artifact, we don't have to be afraid of Qin Tian anymore!" The eldest grandson Wuji arched his hand and said.

Li Shimin nodded, agreeing with the words of the eldest grandson Wuji, he looks at Li Tai now, and the more he looks at it, the more he likes it! His most beloved son gave himself such a big surprise today.

"Father, do you want to go up and try it?" Li Tai suggested at this time.

"It's good!"

Li Shimin has been trying for a long time, but it is just for the sake of face, it is difficult to speak!

"Your Majesty, no, you Ninety-Five Supreme, how can you do such a dangerous thing!" As soon as the eldest grandson Wuji heard that Li Shimin was going to try, he immediately objected.

"Auxiliary, you've been thinking too much, Qingque has tried, it's okay for me to try, no need to say more!" Li Shimin interrupted the eldest grandson Wuji and walked directly into the hanging basket.

Li Tai also followed in, lit the fire, added the fire, and did it in one go! The hot air balloon took off into the air.

Li Shimin watched the figure below get smaller and smaller, and the whole Taiyuan was in full view, and for a while, Li Shimin was full of pride.

With this, he still has something to fear!

"Father, I want to play too, I want to play too!"

"I'm going to fly too, I'm going to fly like a bird in the sky?"

After Li Shimin came down, Li Zhi and Princess Jinyang's little son ran over and pestered Li Shimin to play.

Li Shimin said with a smile: "You have to tell your fourth brother to let him take you fly." ”

"Fourth brother, fourth brother, you take us to fly, okay?"

"I also want the fourth brother to take me flying."

A little Zhengtai, a little Lori, heard Li Shimin say this, so he began to pester Li Tai and asked Li Tai to take them to the sky to play.

"Okay, okay, the fourth brother will take you flying." Although Li Tai's character is not very good, he is still very good to his younger siblings, because they will not pose any threat to him.

After Li Tai flew the two of them again, he was called into the room by Li Shimin.

"Qingque, the artifact you made this must be kept secret, and no one else can know about it, this will be our secret weapon to recapture Datang." Li Shimin called Li Tai to the room and specially instructed that if the production method was leaked, it would easily cause chaos in the world.

"Erchen understands, please rest assured that Erchen will not let others know." Li Tai also knows the importance of this, so he can't tell anyone else.

Li Shimin also reminded what he should have reminded, so he nodded with satisfaction.

Qin Tian, who was far away in the palace, didn't know that Li Tai had invented a hot air balloon, if he was allowed to see it, he would definitely knock Li Tai's head open, wanting to see how Li Tai's head grew and could actually make it.

Qin Tian was writing a business plan for the establishment of the Imperial Bank at this time, and suddenly, his expression was ......
