"I heard that Sun Simiao stayed in Xishan?"

In fact, Li Yong had also heard that Li Er wanted to keep Sun Simiao three times and five times, but Sun Simiao resolutely refused, Li Yong said with a deliberate sigh.

"Alas, if I can't leave, I have to stay, what can I do?"

Li Er suddenly wanted to beat someone when he heard it, I couldn't leave Sun Simiao even though the emperor was so dignified, Sun Simiao said very resolutely that he didn't want to stay in Chang'an, why did he turn around and stay here with Li Yong?

"Why?"

Li Er asked very incomprehensibly, Li Yong smiled and said nothing, just don't tell you, just make you crazy, Li Er strode forward, he really wanted to find Sun Simiao to ask clearly, is he not as good as Li Yong?

"You really don't tell so-and-so?"

"Actually, it's nothing, Sun Daochang just wants to study medical skills, write books, and teach students."

"As a doctor in Tai Hospital, he can also study medical skills, write books, and teach students."

Li Er was very unwilling to say in his heart, Li Yong wanted to say, do you have a microscope?

"Because I have a microscope."

Li Er was stunned, microscope? What's that? Li Er is now messy in the wind, although this newly bought Zhuangzi has not yet been renovated, but Li Er always feels as if he has entered another world as soon as he enters here, Li Er looked back at Li Yong who walked leisurely with his hands behind his back, and asked with a puzzled expression.

"Li Yong, what is a microscope?"

"To put it simply, there are countless tiny organisms on the ground, in the air, and even on the clothes of saints, and such microorganisms are so small that they are difficult to see with the naked eye, and can only be observed with the help of microscopes."

Li Yong explained with a smile.

"There are countless tiny creatures on so-and-so's clothes?"

Li Er looked down at his clothes with a puzzled expression, Li Yong nodded and said.

"Well, hundreds of millions, but it's hard to see with the naked eye."

Li Er was stunned at first, and then laughed directly.

"Or billions? Still hard to see with the naked eye? Hahahaha...... No matter how tiny it is, billions of plans have already crushed something! That's how you used this to fool Sun Daochang? You're too, Sun Daochang actually believed it, it's really laughing to death......"

Li Er smiled back and forth, his eyes were full of laughter, Li Yong stood aside and smiled slightly, looking at Li Er's eyes was like looking at a fool, caring for fools starts with me, ignorance, you ignorant mortals, laughed, Li Er couldn't laugh anymore, because Li Yong's eyes were not quite right when he looked at him, Li Er was surprised.

"You're not fooling Daoist Sun? Are you serious? ”

Li Yong smiled and nodded, Li Er shook his head decisively, it's strange to believe you, you kid is very bad, although Li Er resolutely didn't believe it, but he didn't think to tell Sun Simiao, no matter whether Sun Simiao stayed in Tai Hospital or Xishan, in short, he stayed in Chang'an, which he was happy to see.

"Where's your flying hot air balloon?"

Li Er finally asked the biggest purpose of his trip, of course he was most interested in the hot air balloon, to be able to fly into the sky, from the moment he saw the hot air balloon flying into the sky, his heart was like a cat's paw scratching, but at that time he was angry with Li Yong, I was really embarrassed to come to the Xishan Courtyard to see the hot air balloon, and now he finally took the opportunity to come to the new Lijiazhuang, the most unmissable thing is of course the hot air balloon.

"Put it away, in the warehouse over there."

Li Yong led Li Er to the venue over there, Li Yong's guards carefully dragged the hot air balloon out and then spread it out carefully, Li Er observed everything with interest and commented.

"Such a big hot air balloon is so small when put away, but it is easy to carry."

In fact, he is so interested in hot air balloons, a large part of the reason is that he thinks that hot air balloons can fly, easy to observe the enemy's situation, know themselves and know the enemy, in order to be invincible, this is simply an artifact on the battlefield, the previous telescope has already made Li Er very excited, if the hot air balloon with the telescope is perfect, and, if it is used to siege the city, then the use of the hot air balloon is even greater, siege? Li Er couldn't help but think of the expedition to Goguryeo, if there were a hundred and ten hot air balloons used to attack the city, tsk, it would be beautiful to think about, as Li Yong lit the fire, the hot air balloon gradually became swollen, Li Er looked at the hot air balloon that gradually became round and bigger, and his eyes were full of fire.

"I heard Changle and Pheasant Slave say that the scenery in the sky is so magnificent, and I am also very curious." Li Er said with a smile.

At this time, Li Junxian's face next to him turned pale, although Li Yong and Li Chongyi had taken a hot air balloon, and even Princess Changle and King Jin had also taken a hot air balloon, and they were all very safe, but Li Junxian was still worried when he really saw the hot air balloon, is this thing reliable? If something happens, who can afford it? Li Junxian hurriedly persuaded.

"Saint, it is very dangerous for a hot air balloon to fly into the air, how can a saint be in danger of his safety?"

Li Er waved his hand and smiled.

"It's okay, Li Yong has already flown over with Changle and Pheasant Slave, how can there be any danger?"

Li Junxian turned his head to look at Li Yong and asked.

"Hua Tinghou, is the hot air balloon really not dangerous at all? Can you guarantee the safety of the saints? ”

Are hot air balloons dangerous? Nonsense, of course there is, this primitive hot air balloon is not dangerous, Li Yong has already taken it out and used it, and he will not seal it for so long before taking it out for teaching, there is no absolute, who dares to pat his chest and say that there is no problem, anyway, he Li Yong does not dare, Li Yong said angrily.

"Of course, there are dangers, you may choke to death when you drink water, you may choke to death when eating, you may fall to death while riding a horse, how can there be anything in this world that is completely dangerous?"

The sound of horses' hooves was like thunder, Li Yong, Li Er and others turned around, a group of old hooligans, no, a group of old heroes came on horseback, they heard that the emperor drove to the new Lijiazhuang, and suddenly all of them skipped work and came, to be honest, they were also very curious about the hot air balloon, but they all never came to see the hot air balloon, because they also knew that the emperor must be more curious, the emperor endured not to go, they ran to play happily can it work? They are all old foxes, and they all held back the desire in their hearts, but now that the emperor himself has gone to Sujiazhuang, who can bear it? The hot air balloon had already been inflated, and Cheng Yanjin and the others all widened their eyes and looked at this behemoth curiously and feverishly.

"Good fellow, that's big."

"I don't think I look at it from the sky, but it's really amazing to look at it in front of me."

"Did you really burn it by fire?"

Everyone sighed around the hot air balloon, and Cheng bit Jin slapped his thigh and said.

"Looking at it like this, a hot air balloon is quite simple, it's nothing more than a ball on top, a basket on the bottom, and then a stove to burn the fire, isn't that enough?"

When everyone heard it, it seemed to be really simple, Li Yong smiled.

"Indeed, it's that simple, Uncle Cheng can go back and try it."

Li Er was very moved when he heard it, he could go back and try it, if it was successful, he could be equipped in the army on a large scale, it was nothing more than sewing a ball from cloth, and then hanging a basket underneath, and then adding a stove, how much would it cost? Is it really that simple? Looking at Li Yong's smiling face, they always felt that something was wrong.

"The balloon is about to take off."

Li Yong said with a smile, Li Junxian was immediately anxious when he heard it, and knelt down on one knee and said.

"Saint, don't take risks lightly! Generals, please also advise the saints, it may be dangerous to take a hot air balloon, and the saint is a member of the community, how can he take a hot air balloon? ”

Cheng Yanjin nodded solemnly and said.

"Li Junxian is right, let's let the minister go up and try it first."

Wei Chigong also hurriedly said.

"Saint, I would like to go up and give it a try!"

Xu Shiji said with a smile.

"General Li's worries are not wrong, let's let the ministers and others explore the way and see the situation."

There is such a group of old hooligans, today this hot air balloon has to fly and fly, and if it doesn't fly, it has to fly, so Li Yong didn't bother to care which of them got on and who didn't, and he turned into the basket first, but to Li Yong's surprise, Li Er then followed in without hesitation.

"A certain trustworthy Li Yong."

Li Er smiled at Li Junxian, Cheng Biting Jin and others, Li Yong couldn't help but be stunned when he heard this, he didn't expect Li Er to be so decisive, and trust him so much, the emperor is generally very afraid of death, so seeing Li Er flipping into the basket without hesitation, Li Yong was still a little surprised in his heart, Li Junxian saw that he couldn't persuade the emperor, and hurriedly stepped forward to turn into the basket, as the commander of the palace guards, of course he had to follow the emperor, however, before he could turn into the basket, a big hand knocked him down, The shot is naturally Cheng Biting Jin.

"I'll stay there~"

Cheng Biting Jin quickly flipped into the basket, Li Junxian was very helpless, what can you do when you meet an old killer like Cheng Biting Jin? I can only let it, I will turn it over again, Li Junxian held it with both hands, and then a big hand fell on him again and slammed him down, almost without looking back, Li Junxian guessed who it was, sure enough, it was Wei Chigong, don't you look like this, okay? I'm His Majesty's guard, I have to follow the emperor, just when Li Junxian was about to turn over again, Li Yong had already held him down.

"Four people are the safest."

Li Junxian was dumbfounded, he could only be four people at a time? But as the emperor's bodyguard, he must follow the emperor, his eyes swept over the four people in the basket, the emperor naturally couldn't let it out, Li Yong naturally couldn't let it out, and then Cheng Biting Jin and Wei Chigong, uh, couldn't afford to provoke, originally thought that he could experience flying with the emperor, but he didn't expect to be swept down, the raging flames burned, and the hot air balloon began to slowly fly off the ground, Cheng Biting Jin couldn't help but shout excitedly.

"It's flying, it's really flying~"

The hot air balloon is constantly climbing, flying higher and higher, and the field of vision is getting wider and wider.

"Lying down~ so high!"

"~ The wind is so strong!"

"Look, that's Chang'an~"

Cheng Biting Jin and Wei Chigong exclaimed, Li Er didn't shout at the emperor's majesty, but his face also turned red because of excitement, a magnificent scenery, a panoramic view of the great rivers and mountains, Li Er couldn't help but be proud when he looked at this great rivers and mountains.

"This is all a certain country!"

There's nothing wrong with that.

"It turns out that from the sky, a certain Chang'an is so spectacular!"

Li Er stroked the railing and flew away.

"Li Yong, fly, let's fly over Chang'an."

Cheng Yanjin instigated, he was excited when he first flew up, but he felt dissatisfied at this moment.

Wei Chigong also instigated.

"That's right, let's fly over Chang'an City to have a look."

Today's wind and sun are beautiful, if there is no Li Er in the hot air balloon, it is not bad to fly down, Li Yong shook his head and said.

"Your Majesty is still on the hot air balloon, let's go down."

Cheng Yanjin couldn't help but nod when he heard this.

"That's what Li Yong said, then let's fall first, and when the saint gets off the hot air balloon, let's fly again."

Li Er couldn't help but roll his eyes when he heard this, look at what the two of you said, is this human? Li Er said categorically.

"Li Yong, you don't have to land, fly to Chang'an, I also want to go to Chang'an to see, can I fly to the palace?"

"Yes, yes, the problem is that I am afraid that I will be shot into a sieve before I hit the ground."

Li Yong said calmly, anyway, this hot air balloon can't sit a few people, Li Er shouldn't worry that there will be a large army falling from the sky, although the guards in the palace also know that the hot air balloon is Li Yong's, it should be unlikely to release arrows, but no one is sure, this is a problem, Li Er said.

"Then go down first, let Li Junxian enter the palace and tell the guards not to let go of arrows."

How troublesome is it to fall and fly up again? Li Yong directly took out the pen and ink from the small box next to him and said with a smile.

"A saint can pass it down by hand."

This is a good way, Li Er finished writing with a splash of ink, Li Yong stuffed it into the copper pipe, and the copper pipe fell down the rope with the letter, Li Junxian was stunned when he saw the letter in the copper pipe, didn't he say that he would just go up and take a look? Why do you want to fly to the palace again in the blink of an eye? Li Xiaogong, Hou Junji, Xu Shiji and others couldn't help but scold, it must have been instigated by Cheng Yanjin and Wei Chigong, these two stinky and shameless ones, they haven't been able to go to the sky to see it, what can be done, Li Junxian hurriedly sent guards to gallop into the palace with the emperor's handwritten letter, and on the hot air balloon, Li Yong and others could clearly see more than a dozen small black dots rushing towards Chang'an.

"Walk you~"

Li Yong cut the rope with a knife, and the hot air balloon began to fly slowly towards Chang'an City, today the wind is beautiful, the hot air balloon flies very slowly and steadily, it is indeed a good weather to ride a hot air balloon, and it is also at this moment, Li Er and Cheng Yanjin and others, Yu Chigong really experienced the fun of riding a hot air balloon, fun, very fun.

"Fluttering in the wind, it's really a fairy enjoyment, I really want to fly all over the Tang Dynasty in a hot air balloon, and take a good look at this great country and mountains laid by a certain one."

Li Er said with great interest.

"The saint has all the opportunities, how can he have time to travel the world?"

Li Yong glanced at Li Er obliquely, and decisively poured a basin of cold water on it.

"Did you kid build this hot air balloon just to take this one to travel the world?"

Li Er asked, of course not, he was just a product of many experiments, for Li Er's question, Li Yong thought about it and nodded and replied.

"Not bad~"

Li Er looked at the magnificent mountains and rivers, and couldn't help but snort coldly in his heart, he still wanted to leave Chang'an and travel the world? You're thinking beautifully!
