Great Tang’s Unparalleled National Teacher

Zhangsun Chong is obviously not interested in this issue, but seeing everyone discussing it, I had to glance at it and replied: "Two li is two li."

"I don't think so."

Du Gou put his arms around his chest. He seemed to have different opinions. He also glanced down and said, "I'm looking at a mile and a half."

Zhang Feng nodded, and did not refute, and recorded all what everyone said in the notebook.

These all are important data, even if it’s a mile and a half away from the ground and the hot air balloon has stopped in the air, it means that this time the hydrogen can only support the weight of four people. And to the sky a mile and a half.

If you want to fly higher next time, you need to add more hydrogen, at least more than this time, so that you can basically guarantee a higher flight than this time, so it can be used in the military. on.

On the other hand, if you want to fly lower, add less hydrogen, at least a little less than this time, so you can fly lower than this time. In this case, it can be used in agriculture. .

After recording everything, Zhang Feng was just about to speak, a cold wind blew, feeling the chill, he quickly said: "Throw two sandbags down."

Cheng Chumo and The others had done hot air balloons before and naturally knew what this sandbag was for. It was nothing more than lightening the load and using the direction of the wind to shift the direction. They understood in their hearts that they had a sandbag in their hands and threw them all down.

As the weight on the hot air balloon decreases, the cold wind hits and the direction slowly begins to change.

Soon, the hot air balloon began to turn sharply and float down.

Zhang Feng sat in the basket, holding a pen in one hand and a notebook in the other, recording the wind direction and the speed of the hot air balloon.

The three of Cheng Chumo are cuddling together. It is strange this time. They didn't shout, perhaps because of curiosity. Their three people stared at Zhang Feng's notebook closely, a little puzzled. ,

Zhangsun Chong couldn't help but opened the mouth and said: "Feng'zi, what are you memorizing with a notebook in such a strong wind?"

Zhang Feng gave an angry glance Zhangsun Chong: "You know what a fart, if I don't record it, how many times can your life be kept without experimenting again? I'm afraid it was gone last time."

After that, he no longer paid attention to these three guys.

However, his words made Zhangsun Chong and the others a little uncomfortable.

So I really think I am a little white mouse.

The last experiment?

Resentment belongs to resentment. After thinking about it, this youngster is still responsible.

I also know that you will record it and will not do all reactive experiments.

Thinking about it, Du Gou looked towards Zhang Feng and asked: "Feng'zi, what are your records? Take it out and have a look."

Zhang Feng frowned, put down his pen and glanced at the three of them: "You don't understand, and it's useless to show you. With this time, you can see how far we are from the ground?"

Du Gou Oh There was a sound, and there was no rebuttal. He glanced down, astonished and said: "It's almost there, less than half a mile."

tone barely fell, Cheng Chumo stood up and faced each other. Looking down, sure enough, it’s already not far from the ground, and it’s almost here soon. They cheered and said, "It’s here, it’s coming soon."

Zhang Feng glanced at Cheng Chumo and the others with an angry look. One glance: "When you arrive, you will be there. What makes a fuss about nothing."

Cheng Chumo ate a flat, stared at Zhang Feng, and did not make a sound. He kept talking with Zhangsun Chong and the cheers others.

After about a cigarette time, the hot air balloon swayed, as if it had hit something. Zhang Feng quickly got up and glanced down. It turned out that it had reached the ground.

I was about to tell Cheng Chumo and the others to go down, but unexpectedly these guys were more active than him. As soon as the hot air balloon hits the ground, these guys have already jumped off the ground.

Zhang Feng shook his head and smiled, slowly stepping off the hot air balloon.

Just after coming down, Ma Zhou ran over and looked at Zhang Feng expectantly: "Honored Teacher, how was it just now? Is there any important news?"

Zhang Feng handed over the notebook in his hand to Ma Zhou, with a serious expression: "We were about one and a half to two miles in the sky just now. This is all related to the hydrogen you injected into the hot air balloon. Remember, if it's next time If you want to fly high, you have to release more hydrogen than this time, and the sandbags have to release less. If you want to fly low, you need to inject a little less hydrogen, and the sandbags should also release a little more, understand?"

Ma Zhou handed the notebook in his hand to Hao Chujun, nodded: "Understood, Honored Teacher."

Hao Chujun is also nodded, indicating that he understands.

Zhang Feng glanced at the sun in the sky, and saw that it had gone down the mountain and all around had begun to fog, so he glanced at everyone: "Let’s do this today, I will talk about something later."

Cheng Chumo and the others are finally sighed in relief.

The experiment is finally over, no need to suffer.

They keep cheering, just like celebrating something.

Zhang Feng corner of mouth twitching, do you want to suffer so much in your own hot air balloon? These guys.

Thinking about it, he turned around and was about to leave. At this moment, Hao Chujun spoke. He said somewhat disappointed: "Honored Teacher, will you come tomorrow?"

"Tomorrow will not come."
