Chapter 459: hot air balloon

"Since you can't get to Crow Island by crossing the lake, you can simply fly. The monsters in the cannibal lake are no matter how powerful they are, it is impossible to have the ability to fly."
When Feng Yun came to his tent and was about to open the door of the tent, his mind suddenly flashed, and then an image appeared in his mind.
This time he thought of it as a tool that can be used to fly a man and reach Crow Island from a high place above the surface of the cannibal lake, more specifically, a hot air balloon.
Before he crossed, hot air balloons were not rare gadgets. They appeared frequently in film and television works, and there were even major hot air balloon festivals.
In fact, when Fengyun realized that the Cannibal Lake would become a huge obstacle for his coalition forces to defeat the Raven Tyrant and his Black Raven Tribe, it was not that the hot air balloon had flashed in his mind, but he did not catch it.
It is not easy to make a hot air balloon lift off smoothly and be able to fly with people.
Even in the world before he traveled, it would be a very difficult task for ordinary people to make a hot air balloon that can be used normally, not to mention the primitive society where materials and tools are extremely scarce.
But now that he has been forced to the corner, there is no way to retreat, the problem must be solved.
Therefore, Feng Yun couldn't help but think of the hot air balloon again.
Although it is very difficult to make a hot air balloon under current conditions, this does not mean that there is no possibility of success.
Since it is not completely impossible to succeed, Feng Yun felt that he should give it a try.
No matter how bad the result is, how bad can it go? At best, it is a failure.
But if it succeeds, won't it be able to solve the big problem that plagues everyone?
Feng Yun has never been a hesitant person.
After deciding to make a hot air balloon, Feng Yun acted immediately, but he did not start making it right away. Instead, he opened the tent door, walked in, sat down on the animal skin in the middle of the tent, and closed his eyes. .
After closing his eyes, he can see that his eyeballs are moving under his eyelids again, which shows that he is not going to sleep.
He searched for information about hot air balloons in his mind. He had to figure out the steps and various materials needed to make a hot air balloon.
If you start rashly without understanding this, the odds of success that were not high will become even lower.
After about half an hour, Feng Yun opened his eyes, and he already had a rough shape in his heart.
The steps to make a hot air balloon are not complicated. He also knows the principles very well. The difficulty lies in the materials.
Among these materials, what Fengyun thinks is the most difficult to handle is the two, one is the airbag and the other is the fuel. The former needs to be light enough, otherwise it will not be able to fly by itself, and it must be strong enough.
As for fuel, it seems that it is not difficult to find. There are many things that can be ignited, but it is difficult to find the fuel for hot air balloons.
It must be light enough for the same reason as the airbag. When it burns, it must be strong enough, otherwise the heat it emits will not be enough to make the hot air balloon fly.
Fengyun recognized the difficulty of making hot air balloons, especially under the current circumstances, but he did not choose to give up, and decided to give it a try no matter what.
Feng Yun sorted out the thoughts in his mind, stood up, and walked out of the tent.
He decided to find someone first, he was Feng Lei.
It is too difficult to make a hot air balloon in primitive society. He needs to find a helper and counts on him alone. There is no possibility of success. Even if it succeeds by luck, it must take a very long time, by then the day lily will be cold.
It didn't take long for Fengyun to find Fenglei.
After seeing Feng Lei, Feng Yun took him to a slightly more secluded place and told him his thoughts.
"Brother Lei, do you think my method will work?"
Finally, Feng Yun asked Feng Lei's thoughts.
"I don't know. I didn't even understand what you were talking about."
What Feng Lei gave back to Feng Yun was a face full of blankness.
"It's all for nothing."
Feng Yun couldn't help sighing in secret, and felt a sense of powerlessness in his heart. It was too difficult for a primitive man to understand what a hot air balloon is and how it works.
Feng Yun has never been a person who likes to give up halfway. Now that he has decided to make a hot air balloon, no matter how difficult it is, he is ready to do it.
"Brother Lei, it doesn't matter if you don't understand. I'll show you first and you will understand."
"How to demonstrate?"
Feng Lei's eyes lit up, showing an expression of curiosity and expectation.
Although he still didn't understand what a hot air balloon was, from the bottom of his heart, he was still willing to believe in Fengyun. If a hot air balloon was made, he might actually be able to send people directly to Crow Island.
To be honest, it is not so much Feng Lei believes in hot air balloons as he believes in Feng Yun.
Feng Yun's various practical and novel inventions in the Yan Snake Tribe have already caused him to trust him almost blindly. As long as he said, he would instinctively believe it, including hot air balloons.
"Brother Lei, before the presentation, I want you to help me find something."
Feng Yun thought about it for a while, and made a request to Feng Lei.
"Just tell me. What do you want, tell me, as long as I can find it, I will help you get it."
I don't know if I want to see how Feng Yun will demonstrate, Feng Lei readily agreed.
"You can help me find some resin, bones, and string."
Fengyun reported what he wanted.
"That's it? Anything else?"
Feng Lei breathed a sigh of relief secretly. He was originally worried that Feng Yun would let him look for some weird things, but he didn't expect it to be just some very common things.
"If it's convenient, help me find another piece of leather. Remember it's better to be thinner."
"No problem. Yun, wait a while, I'll find it for you."
Before Feng Lei spoke, he stood up and hurriedly walked out.
"Oh, yes. Brother Lei, you found something and sent it to my tent."
Feng Yun also stood up and shouted at Feng Lei's back.
"understood."
Feng Lei waved his hand to Feng Yun and walked away without looking back.
Feng Yun immediately walked to the tent where he lived.
After entering the tent, he was not idle, and started to get busy nervously.
If you want to do a good demonstration, let Feng Lei understand the working principle of the hot air balloon, understand him, and then try his best to help him, it is not enough to rely on the few things he asked him to find.
