I was a village chief in a primitive society

Chapter 430: Something that can be called perfect. (1 more please customize)

"Tap tap tap......"

Yuying ran excitedly from the first floor to the second floor, with a smile and excitement on her face.

She calmed her breathing and said excitedly:"Witch......Wu, Uncle Gu Mu asked you to come over."

When Lady Fox Ear came back from the sheepfold in the morning, she was stopped by the ancient tree and told that she had something to do with the witch.

"What's wrong? Is the hot air balloon ready?"This was the first thing Su Bai thought of.

Yu Ying nodded heavily and said,"Yes, Gu Mu Shu said that it has been made and I want you to take a look."

Su Bai closed the book in his hand and stood up immediately, saying,"Let's go and have a look."

He can't wait to see if we can successfully make a hot air balloon in this era. It would be great if we succeed."

"Tap tap tap......"

The two stepped out of the cement house and started walking towards Gu Mu's carpenter's office.

More than half an hour later, the two arrived in front of Gu Mu's carpenter's house, which was still a wooden house.

That wooden house looked relatively large, and it was specially built as a carpenter's house. Because many new carpenter apprentices were recruited, the house needed to be larger.

This way we can accommodate more people, and it will be more convenient for Gu Mu to teach them.

"Wu, I have already developed what you want. Can you take a look?"Gu Mu said excitedly.

He didn't bother to take off the mask on his face, and came over with a very excited expression, eager to share the news.

Ever since he got the blueprint, he had been very excited. After knowing the principle, he wanted to show this thing even more.

He felt that the hot air balloon was simply amazing. If he could make it, it would be his own skill.

And he would be more famous in the tribe and could help. The development of the tribe is also very good

"Where? Show me."Su Bai was also a little excited. If the hot air balloon is really successfully developed, it will be of great significance to the tribe.

Not to mention the magical feeling of flying into the sky, just developing this area can also help the tribe a lot.

"Wu, come this way, I placed it in the forest."Gu Mu pointed in the direction of the forest.

Because the area of ​​the hot air balloon is very large, if it is placed in the tribe, it will definitely attract many people to come and see it.

This would be too ostentatious, and the entire tribe will know it.

More What's more, because of the Pink Flower Festival, many women from other tribes came to the tribe, so we have to be more careful.

"Tap tap tap....."

Everyone walked excitedly toward the forest, and met the Horn Girl and they also followed them out of the tribe.

More than half an hour later, everyone arrived outside the tribe and saw a hot air balloon in an empty forest.

Su Bai saw the familiar hot air balloon at first sight. Its appearance was a little different from the hot air balloons on the earth, but not too different.

The only difference is the materials used. Hot air balloons on the Earth side use more rigorous materials.

Hot air balloons on the earth's side are more strictly called sealed hot air balloons, which consist of three parts: a balloon, a hanging basket and a heating device.

The skin of a hot air balloon is made of reinforced nylon (some hot air balloons are made of polyester). Although it is light in weight, it is extremely strong and the balloon is airtight.

The surface of polyester or nylon fabrics should be treated with waterproof and breathable materials, similar to surface coating or composite materials, to ensure that hot air does not escape. Basically, it is made of high-strength nylon 210D composite TPU.

This kind of fabric has high strength, tear resistance, and high waterproofness, and is suitable for aerial photography of airships, hot air balloons, parachutes, etc.

But in this era, there is no such high-end thing, so it can only be replaced by animal skins.

Therefore, the fabric presented in this hot air balloon is sewn from the skin of a slippery lizard, which is both waterproof and durable.

Even if it suddenly starts raining, don’t worry too much. The waterproof animal skin is enough to give the hot air balloon enough time to land.

"Wu, this is the hot air balloon you asked me to make. It is simply amazing."Gu Mu is still very excited.

Every time he gets the drawing and looks at it, he can't calm down for a long time, even more so when he learns its principle.

The upper part of the hot air balloon is in the shape of a big balloon, and the lower part is It is a gondola aircraft.

The air inside the balloon is heated, so it has a lower density than the cold air outside, which acts as buoyancy to cause the entire body to move. These facts are the first he has heard of.

Although it is the first time he has heard of these facts He said, but he felt that these theories were very reasonable and very feasible.

So he was very excited and wanted to present this hot air balloon immediately.

No, he spent a few days to complete this The hot air balloon was fully realized. During this period, I didn't sleep for several nights and stayed up until dawn.

"Very good, pretty much what I imagined."Su Bai nodded with satisfaction. This hot air balloon is perfect.

Although I don't know how to sew the hot air balloon. Looking at it from a close distance, the gaps between the animal skins and the animal skins are sewn very tightly.

And it’s not just one layer. There are three layers in this hot air balloon bag, and each layer is made of different animal skins.

Except for the outer layer of lizard skin, which is tougher and waterproof, the inner two layers are also relatively tough. Durable.

This is to prevent the hot air balloon from accidentally scratching a branch and not falling to the ground immediately.

The reason why three layers of very tough animal skins are used is to prevent some tribes on the ground from using long hair after seeing it. Throw the spears and shoot them up.

If those spears accidentally pierce the hot air balloon, the hot air balloon will also fall, and these three layers of tough animal skins can prevent this.

"Wu, this hot air balloon network is completely made according to your requirements. Let’s see if there are any deficiencies."Gu Mu said worriedly.

This hot air balloon was the first time he came into contact with it, and it was also the first time he did this kind of thing. It was inevitable that he would feel a little unsure.

Although the production process was not difficult, it can be said that it was relatively smooth. Yes, but it is the first time it is made, and it is designed to carry people into the sky.

If the quality of this hot air balloon is not up to standard and causes problems for the people riding in the hot air balloon, he will feel guilty.

"good."Su Bai nodded, approached the hot air balloon and began to observe.

After all, he was going to ride on this hot air balloon later, but he had to observe it carefully.

Although he said that he had self-defense skills now, the hot air balloon suddenly burst. There is nothing you can do if he falls.

So before inflating the hot air balloon, you must first check whether the hot air balloon has passed the test..........................................
