F * ck, did he go up?
Cheng Chumo glanced at the ground in panic and realized that he was already a few hundred meters above the ground. If he fell, wouldn't he become a meat patty?
Thinking of this, he glared fiercely at Zhang Feng, only to realize that Zhang Feng was running on the ground like an ant. It seemed that this bastard was also panicking.
With a burst of pride in his heart, he began to enjoy the scenery in mid-air. He didn't know if he didn't look, but when he saw it, he was shocked. He had never been to the sky before. Now that he looked at it, the sky was full of cotton candy. Even the ground was green, as if it was sprinkled with a large basin of textile paint. It was very beautiful.
Not only that, even the distant mountains seemed to be closer to him. The mountains were covered in silver, and he could vaguely see the proud plum blossoms in the snow. There were also roe deer foraging for food, big bugs hunting, and so on. It was as if all of this was for him.
He stared with his round eyes and looked left and right, completely immersed in the beautiful scenery in front of him, as if he had forgotten the embarrassing scene just now.
At the same time, on the ground, Zhang Feng was leading the group to look for traces of the hot air balloon. To be precise, they were looking for traces of Cheng Chumo. Just now, there was a gust of wind, and this guy swayed with the wind and rose up a lot. Now, they could not see him clearly. Coupled with the snow from last night, it directly blocked everyone's vision.
"Da Bing, Chong, Ma Zhou, Hao Chujun, the four of you search in the east, west, north, and south directions."
Zhang Feng glanced around and instructed everyone. There were only a few faint traces of the hot air balloon, so it would be easier to search by splitting up.
Everyone nodded and set off in four directions at the same time. They knew the severity of the matter and did not hesitate.
"Creak … Creak …"
As the snow from yesterday had not melted, there were some noises on the ground when they walked, but it did not stop them from searching.
Zhang Feng took out a cigarette from his waist and lit it with a lighter. He slowly smoked and walked towards the shadow of the hot air balloon.
In fact, he was not very worried about Iron Bull. That guy had thick skin and flesh, so it would be fine if he fell. Moreover, the hot air balloon was not to be trifled with. There were several layers of silk on top of it. Although it was still a little breathable, it was much better than before, so Iron Bull's safety was not a problem.
However, he was thinking about a problem.
Iron Bull's words made sense. Humans were not pigs. It was impossible to tie them up every time they went up into the sky. However, if they didn't tie them up, they would inevitably panic the first time they went up into the sky. If they panicked, they would be in danger if they moved randomly. It seemed like they had to think of a way to not tie them up.
That's it. Kongming Lantern.
Below the Kongming Lantern, there was something similar to a bamboo basket. If the fire was placed in the bamboo basket, and the silk and iron wires were enlarged and improved, it might be able to carry two people into the sky, or even more.
I'm really a f * cking genius. I'll reward him with a cigarette.
He proudly took a deep puff of his cigarette and continued to walk in the direction where Cheng Chumo had disappeared.
However, if there were too many people, how would they control the direction? Even the brazier is not safe? What if it caught fire? Moreover, it was not a good idea to rely on the wind. What if there was no wind when they wanted to fly?
This series of problems gave him a headache. Logically speaking, there was nothing to worry about. However, this was his personality. He either did not do it or did it to the best of his ability. Suddenly, a bold idea appeared in his mind.
Hydrogen?
Hot air balloons in the future were filled with hydrogen and helium, which were lighter than air. If these two types of gases were poured into the hot air balloon, wouldn't it be the same as the hot air balloons in the future? The problem just now would also be solved.
Thinking of this, he kept recalling the method of making hydrogen that was taught by his teacher in the future.
At that time, he had done this experiment with his own hands. Half of a glass cup was filled with water. When the water was added, a large amount of gas, including hydrogen, had already entered the cup. Then, a little salt was added to the cup because salt could help conduct electricity. Then, a cardboard board was used to cover the cup. Then, two 30-60 centimeter long wires were inserted about five centimeters apart from the cardboard board, and five to seven centimeters of the wires were submerged in the water.
Then, the other end of the wires was connected to the positive and negative poles of the power source. Soon, he would see that bubbles were produced near the wires in the water. Hydrogen was produced at the negative pole, and oxygen was produced at the positive pole. Then, he found a container, inverted the container, and sank it into the glass cup. Slowly, the glass cup was pulled up without leaving the water. The final result was that the glass cup was protruding from the water and filled with water. This way, he could obtain hydrogen.
Most of the things in this experiment could be replaced by other things. The glass cup could be used as a bowl, the salt itself could be found, and paper was needless to say. The wires could be made with copper wire in the forge, but where would the electricity come from?
