"Since you can't get to Crow Island by crossing the lake, it's better to fly. Pen, fun, pavilion www. biquge。 infoNo matter how powerful the monsters in the cannibal lake are, they can't have the ability to fly. ”

When Fengyun came to his tent and was about to open the tent door, a flash of inspiration suddenly flashed in his mind, and then an image popped up in his mind.

This time, he thought of a tool that could fly people to Raven Island from a high place above the surface of the Cannibal Lake, and more specifically, a hot air balloon.

Before he crossed, hot air balloons were not a rare thing, and 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 Raven and his Black Crow Tribe, the shadow of the overheated air balloon flashed in his mind, but he didn't catch it.

It's not easy to get a hot air balloon into the air 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 working hot air balloon, let alone in a primitive society where materials and tools were extremely scarce.

But now that he has been cornered, there is no way back, and the problem must be solved.

Therefore, Fengyun couldn't help but think of hot air balloons again.

Although it is very difficult to make a hot air balloon under the current conditions, this does not mean that there is no possibility of success.

Since it is not completely impossible to succeed, Fengyun feels that he should give it a try.

No matter how bad the result is, how bad can it be, at most it is just failure.

But if we succeed, wouldn't we be able to solve the big problem that plagues everyone?

Fengyun has never been a hesitant person.

Deciding to make a hot air balloon, Fengyun immediately went into action, but instead of starting to make it right away, he opened the tent door, walked in, sat down on the animal skin in the middle of the tent, and closed his eyes.

When the eyes are closed, you can see the eyeballs moving under the eyelids, which means that he is not going to sleep.

He searched his mind for information about a hot air balloon, and he first had to figure out the steps and materials needed to make one.

If you start rashly without understanding this, the odds of success will become even lower.

After about half an hour, Fengyun opened his eyes, and he already had a rough prototype in his heart.

The steps of making a hot air balloon are not complicated, and he knows the principle very well, and the difficulty lies in the materials.

Among these materials, Fengyun feels that there are two things that are most difficult to get together, one is the airbag, the other is the fuel, the former needs to be light enough, otherwise it will not be able to fly on its own, not to mention manned, and at the same time it must be strong enough.

Fuel may seem easy to find, and there are many things that can be ignited, but it is difficult to find fuel for a hot air balloon.

It needs to be light enough for the same reasons as an airbag, and it needs to burn violently enough, otherwise it won't emit enough heat to make the balloon fly.

Fengyun realizes the difficulty of making a hot air balloon, especially in the current situation, but he doesn't choose to give it a try and decides to give it a try no matter what.

Fengyun gathered the thoughts in his mind, stood up, and walked out of the tent.

He decided to find someone first, and he was Wind Thunder.

It was too difficult to make a hot air balloon in a primitive society, he needed to find a helper, and counting on him alone, there was no possibility of success. Even if you succeed, it will take a very long time, and the daylily will be cold by then.

It didn't take long for Fengyun to find Wind Thunder.

After Fengyun saw Feng Lei, he took him to a slightly more secluded place and told him what he thought.

"Brother Lei, do you think my method will work?"

At the end, Fengyun asked Fenglei what he thought.

"I don't know. I didn't understand what you were saying. ”

Wind and thunder gave back to Fengyun with a face full of confusion.

"It's all in vain. ”

Fengyun couldn't help but sigh secretly, and a sense of powerlessness spontaneously arose in his heart, it was too difficult for a primitive person to understand what a hot air balloon was and how it worked.

Fengyun has never been a person who likes to give up halfway, and since 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 a little bit and you'll understand. ”

"How?"

Feng Lei's eyes lit up, revealing an expression of curiosity and expectation.

Although he still hasn't figured out what a hot air balloon is, in his heart, he still wants to believe in Fengyun, and if he makes a hot air balloon, maybe he can really send people directly to Raven Island.

To be honest, it is not so much that Feng Lei believes in hot air balloons, but that he believes in Fengyun as a person.

The various practical and novel inventions that Fengyun had made in the Flame Snake tribe had already made him trust him almost blindly, and as long as he said it, he would instinctively believe it, including hot air balloons.

"Brother Lei, before the demonstration, I want you to help me find something. ”

Fengyun thought for a moment and made a request to Fenglei.

"Say it. Whatever you want, you tell me, and if I can find it, I'll get it for you. ”

I don't know if I want to see how Fengyun will demonstrate, so Fenglei happily agreed.

"Just help me find some pine resin, bones, and string. ”

Fengyun reported what he wanted.

"That's all, anything else?"

Feng Lei secretly breathed a sigh of relief, he was originally worried that Fengyun would let him look for something strange, but he didn't expect it to be just something very ordinary and common.

"If it's convenient, find me another leather, preferably thinner. ”

"No problem. Yun, you wait a while, I'll help you find it. ”

Before Feng Lei could speak, he stood up and hurried out.

"Oh, yes. Brother Rei, you've found something, send it to my tent. ”

Fengyun also stood up and shouted at the back of Feng Lei.

"Got it. ”

Feng Lei waved his hand to Fengyun and walked away without looking back.

Fengyun immediately walked towards the tent where he lived.

After entering the tent, he was not idle, and began to get busy nervously.

If you want to do a good demonstration, let Feng Lei understand how the hot air balloon works, understand him, and then help him with all his might, it is not enough to rely on the few things he asked him to find. (To be continued.) )
