Great Tang’s Unparalleled National Teacher

The two Hao Chujun saw that they were also shot while lying down. They were at a loss for a while, so they looked towards Zhang Feng and were about to speak, but Zhang Feng stopped them with a wave of his hand, laughed looked towards Cheng Chumo and the others: “Iron Ox, I know you are cold in the sky, but this is for science, for Great Tang, you sacrifice once, as for Ma Zhou, they can’t go to heaven…”

” Why can’t they go to heaven? Are you cheating us?”

Du Gou was a little unconvinced.

“Do you think their physique can go to heaven?”

Zhang Feng snorted, said angrily: “Besides, if they go to heaven, who is recording data underground, you Is it?”

Everyone looked at each other in blank dismay.

Although they don’t know what data is, it should be a very important thing to see Feng’zi say so solemnly vowed. It’s not too much to say.

It’s just…

The matter of God is still somewhat repulsive in my heart.

I was thrown down last time, and now I am going again. Everyone is a little bit reluctant.

Cheng Chumo said embarrassingly: “Feng’zi, it’s not that we don’t want to go to the sky, but it’s a bit too cold here, can we take it easy? Or let’s find some people?”

He has already thought about it. As long as Feng’zi agrees, he will go out and find some irrelevant people, at worst, pay some money.

However, Zhang Feng obviously doesn’t think so. He is frowned and hates these guys’ shirk words. He waved his hand: “No, you’ve been up there before. You have experience. I’m not worried about letting others go. Let you get something to protect you from the cold, is that okay?”

Cheng Chumo looked at Zhangsun Chong and couldn’t help but said, “Well, you should prepare more. “

Zhang Feng nodded, then looked towards Ma Zhou and the others: “You go and prepare something to keep out the cold, try to hurry up.”

Ma Zhou and the others are not inked , Turned around and ran away. After a while, they came back with all kinds of quilts and coats.

Zhang Feng took a look at it, and then handed it to Cheng Chumo and the others: “Come on, I will give you all the quilts and coats. Put them on and go up.”

Cheng Chumo and the others took the cotton-padded clothes reluctantly and slowly boarded the hot air balloon.

Everything is ready, Zhang Feng looked towards Ma Zhou and the others: “Untie the hemp rope and take off.”

Ma Zhou nodded, quickly untie the hemp rope, The hot air balloon rises slowly at a speed visible to naked eye.

This time has stabilized a lot. It hasn’t been swayed like the last time, and it has been rising. Cheng Chumo and the others seem to be used to all this, and they didn’t yell, just sat in a basket in a daze.

The hot air balloon flew higher and higher, slowly passing through the clouds, about 5 minutes of time, and finally stopped in the sky.

Cheng Chumo and the others sat in the hot air balloon, cuddling each other, their eyes scattered, as if everything outside had nothing to do with them.

On the ground, Zhang Feng held his head high, glanced at Ma Zhou and the others from time to time, and said: “Please remember, seal the mouth with wax water, the hot air balloon is obviously much more stable, and there is no sloshing anymore. In the case of, there should be no air leakage.”

The two of them screamed and wrote Dragon Snake on the notebook.

This experiment is very important to them. It not only solved the importance of air leakage, but also stabilized a lot, which is undoubtedly a huge improvement.

However, they soon thought of other problems.

Iron Ox just came down because of a leak. Now that the problem has been solved by Honored Teacher, how can these guys get down now?

The air in the hot air balloon is blocked. As long as the air is not exhausted, it will be difficult for them to get down.

Thinking about it, Hao Chujun quickly asked: “Honored Teacher, wait for the Iron Ox big brother, how do they get off?”

How do they get off?

Zhang Feng frowned.

He suspects that this guy is already stupid in reading. Didn’t he just come down?

He replied in anger: “How did you get down just now, are you stupid?”

“Honored Teacher, did you forget?”

Hao Chujun complexion changed and quickly reminded: “Iron Ox big brother and the others just came down because of a gas leak. Now you have blocked this drawback, how do they get down now?”

Zhang Feng startled.

Hao Chujun’s words reminded him.

Yes, I have blocked this drawback.

As long as the qi inside is not exhausted, these guys will have a hard time getting off, unless…

He glanced at the two of them and quickly said: “Is there any preparations on the hot air balloon just now? Sandbags and other heavy objects?”

The rise and fall of a hot air balloon is related to the inner Qi temperature of the sphere. When the inner Qi temperature of the sphere is high, the balloon’s gravity decreases. When the buoyancy is less than that, the balloon rises and the air temperature inside the sphere decreases. , The buoyancy generated by the sphere is less than the weight and load of the sphere itself, and the balloon begins to descend.

However, this method cannot be used in the hot air balloons that have been developed so far.

So, you can only rely on heavy objects, such as sandbags.

Because the wind direction at different heights is different, the airflow produced is also different. If you want to ascend, then drop the weight carried by the hot air balloon, and follow the wind direction of the airflow, which will change the direction and height.
