It seemed that his guess was correct. The hydrogen gas had been successfully collected.
"Feng Zi, what exactly do you have in there?"
Cheng Chumo scratched his head and looked at the silk in confusion.
"You don't have to worry about that."
Zhang Feng waved his hand and ignored the ignorant question. He then looked at Ma Zhou and said, "Ma Zhou, Hao Chujun, you two continue to collect according to the method just now."
"Yes, Master."
The two of them answered in unison. They were actually a little confused, but seeing that their master was unwilling to explain, they did not ask.
Then, Ma Zhou and Hao Chujun began to experiment according to Zhang Feng's experiment. They were very serious. In order to prevent mistakes, Zhang Feng guided them from the side. After about half an hour, the silk was completely filled with hydrogen gas.
However, hydrogen gas was lighter than air. Once it was filled, it would directly rise into the air. In order to prevent this, Zhang Feng, Ma Zhou, and Hao Chujun held onto the silk tightly, afraid that it would slip away. In the end, the three of them were clearly not heavy enough to hold down the hydrogen gas. The tips of their feet were floating.
"Tie Niu, Da Bing, Buggy, hurry up and help."
Zhang Feng held onto the silk with one hand and shouted at the three of them.
There was no other way. The three of them were simply unable to suppress the hydrogen gas in the silk. They needed the help of these fat and thick guys.
"Oh, oh, coming."
Cheng Chumo responded carelessly. He could also see the seriousness of the matter. He went forward and grabbed a corner of the silk. In an instant, it floated down. It had to be said that these guys were really good at suppressing the weight.
Zhangsun Chong and Du Gou were not to be outdone. They went forward and used Monkey Hangs Tree. The silk finally stopped rising and stabilized in the air.
"Feng Zi, what exactly is this thing? Why is it floating in the air? "
Du Gou panted heavily and looked at the silk floating above his head with a puzzled expression.
"There is some gas in the silk. Even if I explain it to you, you won't understand. In any case, we will rely on this thing to ascend into the sky later."
Zhang Feng used a hand to wipe the sweat on his forehead and casually explained. He wanted to let everyone know the importance of this thing. Otherwise, if the ignorant person suddenly let go, it would not be worth it.
"What? Is this a divine object that can reach the heavens? "
Zhangsun exclaimed. He originally thought that this thing was not that important, but now it seemed that it was really amazing. No wonder Feng Zi treated it as a treasure. It turned out that it was a divine object that could reach the heavens. Thinking of this, he exerted more strength in his hand, as if he was ready to hold this thing tightly in his hand.
The other two were the same. At first, they didn't care about this experiment, but now it seemed that this thing could actually pull people up. It was really not something ordinary things could compare with. No wonder it was said to be a divine object that could go to heaven. When they thought of going to heaven, the strength in their hands increased.
With everyone's unrelenting efforts, Silk finally showed no signs of flying up again. It remained in the air, motionless. Seeing this, Zhang Feng heaved a sigh of relief. However, it was impossible to keep holding on like this. He looked at Hao Chujun and said seriously, "Hao Chujun, let go gently now and see if you can leave."
"Yes, teacher."
Hao Chujun nodded and gently loosened his grip. At first, the silk didn't move, but the moment he loosened his grip, the silk rose slightly.
"Quick, everyone, press harder."
Zhang Feng glanced at the crowd and hurriedly pressed down with force.
In fact, even without Zhang Feng's reminder, everyone could feel the abnormality in their hands. They subconsciously exerted force together, and the silk suddenly sank down. Immediately, there were no signs of it floating up.
Seeing this, Zhang Feng let out a long breath and turned to look at Hao Chujun. "Hao Chujun, go get the green brick now. The sooner the better."
"Yes, teacher."
Hao Chujun cupped his hands and turned to run out of the door.
"Feng Zi, what do you need the green brick for?"
Cheng Chumo asked curiously. He didn't dare to relax his grip at all.
"Without the green brick, how are you going to let go?"
Zhang Feng glanced at Cheng Chumo and said unhappily.
"You're right."
Cheng Chumo chuckled. He didn't think too much about it. It was just that this thing was new to him.
Zhang Feng did not pay any attention to this fellow. Instead, he raised his head and glanced at the silk. He could not help but marvel in his heart. Now, there were a total of five people, including himself, who were pulling the silk. Each person weighed a total of one hundred and fifty kilograms. Ignoring Chen Tieniu's fat and thick body, there was a total of seven hundred and fifty kilograms. The hydrogen gas was actually able to withstand such a heavy weight.
In other words, this hydrogen gas could easily carry four people into the sky. If it was light, it could even carry five people. He had to test it out later.
Just as he was thinking, Hao Chujun brought 30 green bricks and stacked them under his feet.
"Teacher, the green bricks are here. What do we do now?"
Hao Chujun wiped the sweat off his forehead. It seemed that he was quite tired.
