In fact, Su Cheng had also heard that Li Shimin wanted to keep Sun Simiao behind again and again, but Sun Simiao refused firmly.

Su Cheng deliberately sighed: "Oh, I can't drive it away, I have to stay. What can I do?"

When Li Shimin heard this, he suddenly wanted to beat someone. I was so fucked that even the emperor could not keep Sun Simiao. Sun Simiao firmly expressed that he didn't want to stay in Chang'an, so why did he just turn around and stay with Su Cheng and stop leaving?

"Why?" Li Shimin asked in confusion.

Su Cheng smiled without saying a word, just not telling you, just to drive you crazy!

Li Shimin walked forward with great strides. He wanted to ask Sun Simiao clearly, is his dignified emperor not as good as Su Cheng?

"Master Sun?"

"I have seen Your Majesty!"

"I heard that Master Sun stayed in Sujiazhuang?"

"Yes, I am going to stay in Sujiazhuang to study medical skills, write books and teach students." Sun Simiao said calmly.

"As a medical officer in the Imperial Hospital, Taoist priests can also study medical skills, write books and teach students." Li Shimin was very unwilling to accept it.

Sun Simiao asked back: "Does Your Majesty have a microscope?"

Li Shimin was confused. A microscope? What is that?

Sun Simiao bowed and passed by, leaving Li Shimin alone in the wind.

I always feel like I have entered another world as soon as I enter Sujiazhuang. Li Shimin turned around and looked at Su Cheng who was walking leisurely with his hands on his back, and asked with a puzzled look: "Su Cheng, what is a microscope?"

"Simply put, there are countless tiny creatures on the ground, in the air, and even on His Majesty's clothes. Such microorganisms are so small that they are difficult to see with the naked eye. They can only be observed with the help of a microscope." Su Cheng explained with a smile.

"There are countless tiny creatures on my clothes?" Li Shimin looked down at his clothes with a puzzled look on his face.

Su Cheng nodded and said, "Well, there are hundreds of millions, but it is difficult to see with the naked eye."

Li Shimin was stunned for a moment, then laughed!

"Billions of millions? It's hard to see with the naked eye? Hahahaha..."

"Even if it is small, billions of dollars will have crushed me long ago! You used this to fool Master Sun? You are so irritating. Master Sun actually believed me. I was so laughing to death..."

Li Shimin smiled so hard that he leaned back and forth, and his eyes burst into laughter.

Su Cheng stood aside and smiled slightly, looking at Li Shimin like a fool.

You ignorant mortals!

After laughing, Li Shimin couldn't laugh anymore because Su Cheng looked at him incorrectly.

Li Shimin said in surprise: "Aren't you fooling Master Sun? Are you serious?"

Su Cheng nodded with a smile.

Li Shimin shook his head decisively, it would be strange if he believed you, you are such a bad boy.

Although Li Shimin firmly refused to believe it, he did not think about telling Sun Simiao that whether Sun Simiao stayed in the Imperial Hospital or Sujiazhuang, he was always in Chang'an, which was something he was happy to see.

"Where is your hot air balloon that can fly?" Li Shimin finally asked about his biggest purpose for this trip.

What he is most interested in is of course the hot air balloons, which can fly in the sky!

From the moment he saw the hot air balloon flying in the sky, his heart was like a cat's paws, but he was angry with Su Cheng at that time, and he was really embarrassed to come to Sujiazhuang to watch the hot air balloons.

Now that he finally took the opportunity to come to Sujiazhuang, the most important thing he must-see is of course the hot air balloon.

"Put it away, it's in the warehouse over there." Su Cheng led Li Shimin to the venue over there, and the guards carefully dragged the hot air balloon out and spread it out carefully.

Li Shimin observed everything with interest and commented: "That big hot air balloon is so small to put away, it is easy to carry."

In fact, a large part of the reason why he is so interested in hot air balloons is that he thinks hot air balloons can fly and make it easier to observe the enemy situation.

Only by knowing oneself and one’s enemy can one be defeated in a hundred battles.

This is simply a magical tool on the battlefield!

The previous telescope had already made Li Shimin very excited. It would be perfect if the hot air balloon was paired with a telescope.

Moreover, if used to siege the city, the hot air balloon will be even more useful!

Siege?

Li Shimin couldn't help but think of conquering Liaodong. If there were a hundred hot air balloons to attack the city, it would be very beautiful to think about it.

As Su Cheng ignited, the hot air balloon gradually became bulging.

Li Shimin looked at the hot air balloon that gradually became round and bigger, and his eyes were full of heat.

"I heard Changle and Chi Nu talk that day that day that the scenery in the sky was as magnificent as it was, and I was very curious!" Li Shimin said with a smile.

Li Junxian next to him turned pale. Although Su Cheng and Cheng Chumo were overheated, and even Princess Changle and King Jin were overheated, it was very safe, Li Junxian was still worried when he saw the hot air balloon.

Is this thing reliable?

If something happens, who can bear the responsibility?

Li Junxian hurriedly said, "Your Majesty, it's so dangerous to fly into the air. Your Majesty is so safe for the country. How can you take risks easily?"

Li Shimin smiled and said, "It's okay, Su Cheng has already brought Changle and the pheasant slaves to fly by. How can there be any danger?"

Li Junxian turned his head and looked at Su Cheng and asked, "Mr. Ankang County, is there really no danger at all? Can you guarantee Your Majesty's safety?"

Is hot air balloon dangerous?

Nonsense, of course there is. Although the system says that safety is guaranteed, Su Cheng still thinks this thing is a bit dangerous.

After all, nothing is absolutely absolute.

Su Cheng said angrily: "Of course there is danger. You may be choked to death when drinking water, you may be choked to death when eating, and you may be thrown to death when riding a horse. How can there be no danger in this world?"

The horse's hooves sounded like thunder. Su Cheng, Li Shimin and others turned around. A group of old hooligans, no, a group of old heroes came one after another.

When they heard that the emperor's emperor's emperor had arrived in Sujiazhuang, they all came over the work.

To be honest, they are very curious about hot air balloons, but they have never seen them.

Because they also knew that the emperor must be even more curious. The emperor insisted on not going. Can they come and play happily?

Everyone was an old fox, and they all held back their desires. But now that the emperor himself has gone to Sujiazhuang, who can still bear it?

The hot air balloon had already bulged, and Cheng Yaojin and others all stared at the giant with curiosity and enthusiasm.

"What a big guy, that's so big!"

"I don't think it's in the sky, but it's amazing when I put it in front of me!"

"It really got burned by fire!"
