"Uncle Cheng, why do you believe in those illusory things? Where did the Heavenly Palace come from in this world?"

Xiao Zhengta looked at Cheng Yaojin with a chuckle. He really didn't expect that this big and thick man would believe that.

"Hmph! I'm not a god, aren't I here to fly here? Old Man Cheng, are you scared?"

Qin Qiong looked at Cheng Yaojin with contempt, and from time to time he stretched out his wide palm, wanting to touch the clouds beside him.

"Don't you, do you think I'm an old slut?"

After hearing Qin Qiong's words, Cheng Yaojin was furious and glared at him. He was just sighing, how could he be cowardly? In his dictionary, there was no word "fear".

"Two...two...two old men! What's the matter with you quarrel?"

Cheng Yaojin's words almost made Changsun Wuji spit out a mouthful of old blood. He kept standing quietly aside, not calling anyone or provoking anyone, why did he get caught in the attack for no reason?

"Pooh!"

In response to Changsun Wuji's rebuttal, the two old guys spat at the side in unison, just flying for a while. Looking at the way he was scared, he was really ashamed to be with him.

"you……"

Such a move immediately made Changsun Wuji stare at him, but he was helpless because he was really scared, and even now he felt that these legs no longer belonged to him.

"The two uncles and uncles are afraid of altitude, which is not a shame. When choosing the Air Force in the future, all soldiers will need to be screened, and not everyone is suitable for this position."

Xiao Zhengta is really unable to see it. Afraid of heights is similar to motion sickness. It is an instinctive reaction of the body and is not embarrassing. However, it is too much for these two old guys to do this. He must popularize their homework for them.

"There's still this?"

The two looked at Xiao Zhengta half-believingly. Why have they never heard of such a statement and such a disease before?

"Zhi Nu, the huge cloud group in front is good, let's go in and take a walk!"

Li Er had long been accustomed to these guys, and did not take these things into consideration. He still looked at the distance with great enthusiasm, pointed his hand at a huge cloud, full of yearning.

"Father, let's forget it. The so-called cloud cluster is nothing more than water vapor condensed. The interior is made of cold air and water droplets. If you break in like this, your body will be unable to bear it. Father, you must protect the dragon body!"

Those who don’t know are fearless, so Xiao Zhengtai knows very well that they can have such ideas, so he whispers to popularize relevant knowledge to everyone, so as to avoid such dangers in the future.

"I see!"

Li Er pretended to be in a daze, nodded heavily, and let Xiao Zhengtai control the hot air balloon float in the sky.

"Your Highness, how high are we flying now?"

Looking at the smaller and smaller Chang'an City below, Cheng Yaojin couldn't help but ask, but his eyes were even more curious.

"It's hard to say, it should be a few hundred meters high."

After Xiao Zhengta made a rough calculation, he gave a similar answer. He didn't know how many of them were.

What?

In just a moment, they had already flew hundreds of meters, which was really incredible.

"Zhi Nu, what is above the sky? Can you take your father to see?"

Li Er looked up and still couldn't see through the clouds, but the desire for knowledge in his heart kept telling him to go up and take a look.

"This...Father...it's really impossible to do with this thing!"

Xiao Zheng was a little helpless. Why are the requirements getting higher and higher? Isn’t it like riding a hot air balloon and trying to enter space?

"What? Is this aversion to be difficult?"

Li Er was very puzzled. Isn’t this thing rising all the time? Moreover, when he saw the so-called sky, it was not very high and continued to fly, he should be able to break out soon.

"Father, what you think is too simple. It is impossible to pass through the atmosphere with a hot air balloon.

Let’s not talk about whether it can fly so high. It just supplies the oxygen we breathe, and even if we fly to that height, we will be suffocated to death.

Without oxygen, it won't continue to burn, and then our fate is to fall from here and smash it to pieces!"

Xiao Zhengtai knew that if he didn't say it seriously, Li Er wouldn't be afraid at all and had to go there and make some excuses.

"It's so serious. My father saw that the sun is not very far away from us. Why don't we go there and take a walk?"

Li Er's face looked a little ugly. He could hear what Xiao Zhengtai meant. Now this height was almost at the limit of the hot air balloon. If they continued to fly, they were likely to encounter big problems.

"Father, your request is more difficult than the one just now. The sun is in the universe, and all planets revolve around the sun, and the same is true for the earth where we live.

Even if the technology is mature in the future and can fly outside the universe, it is impossible to reach the sun because the sun is a huge ball of flame, and its temperature is terrifyingly high.

Take steel as an example. I am afraid that before it reaches the sun, steel has already turned into iron and was wiped out. As for wanting to go to the sun, it is simply unrealistic. Nothing can withstand its heat."

Xiao Zheng shook his head quickly. What do these guys think about their heads? Do they like these things that are seeking death? Even there is no such technology in later generations, let alone now.

ah?

After hearing Xiao Zhengtai's words, everyone was shocked, their eyes full of disbelief. It was obvious that they were not far from themselves, so how could they be so scary?

"Zhinu, who did you hear these things? Why do you understand them so much?"

After pondering for a moment, Li Er then looked at Xiao Zhengta with deep meaning. Since he understood so much, if he was not mistaken, this little guy should have been secretly with him on his back.

"I wonder if my father has ever heard this saying: It is better to travel thousands of miles or walk thousands of miles than to guide the way for masters than to read thousands of books.

My sons also went out for a trip and happened to meet some strange people. These people's academic and insights were far beyond ordinary people, but they did not have the greed of the world and were devoted to satisfying their desire for knowledge.

The sons knew this knowledge only after following them to communicate. The sons did not know whether it was true or not.

The father is the magnificent of the nine fives, and he must not take risks easily. It is because the father said he wanted to travel to Chang'an City that his son would agree to bring his father up. If the father wanted to take risks, the son would rather resist the order than let his father take risks!”

Regardless of whether Li Er was angry or not, Xiao Zhengtai directly blocked Li Er's next request, his affairs, his secrets, and he must not tell others about excuses, and he will never try the risks.
