Chumo winks back, and the two of them instantly understand.

Chang sun Chong looked at Zhang Feng and said, "OK, let's go."

Zhang Feng smiled. In fact, he had guessed the result just now and said, "OK, go up now. I promise you are not in danger."

In fact, what he said was also well founded. The last accident could only be said to be an accident, but this time it was different. The seal was reinforced again, and he only experimented for a while, so he dared to let three people go up, otherwise he wouldn't dare to give him ten courage.

Chumo and Chumo don't think so. They are still immersed in the pain of the last injury, but they have reluctantly agreed to Fengzi, so they have to climb the hot-air balloon reluctantly.

Zhang Feng's coke broke and hurriedly greeted Ma Zhou and Hao Chujun: "ready to take off."

As soon as they listen, they put a pair of scissors on the hemp rope connecting the green bricks, ready to cut at any time.

Chumo and Cheng on the hot-air balloon are a little uncomfortable. They hold the basket with their hands and look desperate.

I thought I had just been thrown last time, and I would be thrown again this time. Why is my life so hard.

But these are not up to them. Since they have been on the thief ship, there is no reason to go down.

With a click, the hemp rope was cut and the hot-air balloon floated up slowly.

At first, there was nothing. It was very stable. It felt the same as sitting before, but as it got higher and higher, it swayed.

This frightened the three people and yelled in the basket.

"Feng Zi, you fucking hurt me again."

"Help, I don't want to die."

They huddled together and cried for their parents.

Zhang Feng, with his hands on his hips and his head raised, seemed to have nothing to do with him.

In fact, he has been listening carefully to all this. After all, he has just taken off and doesn't fly high. The voice is very loud.

It's not that he doesn't worry about Chumo and others. On the contrary, he is very relieved.

The balloon has been reinforced and its stability is much better than before. Besides, it's just flying for a few incense sticks. There's no danger at all. On the contrary, these guys have been crying on it, which makes people upset.

Thinking about it, the cry gradually decreased.

Zhang Feng glanced and found that the hot-air balloon was drifting away. He turned his head and glanced at Ma Zhou and others: "go, catch up and have a look."

Chumo and others, on the other hand, felt that the hot-air balloon swayed at first and almost fell down. Now they are all right.

They looked at each other, let go of their hands, and lay down beside the basket to watch. Their fear was even a little less.

"Look at that. It's Kushan."

"Over there is Chang'an city."

They slowly let go of themselves, as if they found a new world.

After watching for a while, there was a hissing sound from the hot-air balloon, and then it began to descend.

This decline is a little different from the last time. Last time, there was a sudden leak of air, but this time it was relatively slow, just like blowing air. If you don't listen carefully, there is no gap at all.

The three of them sat in the basket until they saw that they were getting closer and closer to the ground.

"Ah, how did it fall?"

"Yes, how is it getting to the ground? Didn't Feng Zi say he wanted some incense?"

While talking, the hot-air balloon has fallen to the ground and landed steadily without any ups and downs.

They hurried down the basket and looked curiously in front of the hot-air balloon.

But at this time, Zhang Feng came with Ma Zhou and Hao Chujun.

"Feng Zi, why did we come down so soon?"

Chumo looks at Zhang Feng and looks puzzled.

Zhang Feng glanced at the hot air balloon and said with a smile, "why? Do you still want to continue playing in the sky?"

Chumo waved his hand again and again. Although the hot-air balloon gave him a good experience, who dares to joke about his life? He hurriedly said, "that's not true. I'm just curious. Didn't you say you wanted some incense just now? Why did you come down so soon? Is there a problem?"

Chang sun Chong and Du Gou also looked at Zhang Feng curiously.

However, Zhang Feng didn't answer immediately. Instead, he walked around the hot-air balloon for several times. Finally, he checked the seal again and showed an expression of sudden enlightenment. Then he looked at the people: "in fact, I didn't know just now. Now I know."

With that, he looked at Ma Zhou and Hao Chujun and said seriously: "remember, you can't use hemp rope for sealing next time. The reason why it drops too fast this time is that there is too little air impact, and the gap in the hemp rope is too large. If you use hemp rope next time, it will be the same as this time."

No hemp rope?

Ma Zhou and Hao Chujun are a little confused.

If you don't use hemp rope, what do you use?

They wanted to ask, but when they thought that the teacher might have to arrange, they quickly recorded it in the book and said in unison, "yes, teacher."

Zhang Feng nodded, then looked at Chumo and others, and asked seriously, "did you feel anything unusual on it just now? This is very serious. It may be related to human life in the future. You can think about it."
