I was a village chief in a primitive society

Chapter 427: Everyone is convinced. (2 more please customize)

"Yes, this way our feet are off the ground, and the flying speed of the hot air balloon is not slow, so it is a means of transportation."Su Bai said with a smile.

In this era, he doesn't want to get too entangled. The best way to communicate is to be simple and easy to understand. It's not good to tell them that it's too complicated, otherwise they won't understand, and he has to spend more words. Explain.

It is better to do it as simple as possible, so that neither party will be embarrassed and the other party can clearly understand

"Wu, what does a hot air balloon look like?"Yu Ying asked curiously.

The fox-eared lady's pink fox tail kept wagging, her face was full of anticipation, and she fiddled with the glasses on the bridge of her nose from time to time.

"It's something similar to a balloon. You'll know when I draw it."Su Bai said lightly.

He didn't know how to describe it to the fox-eared lady. It would be more intuitive to draw it directly. At this time, he was very lucky that he had good painting skills on the earth, otherwise his farming plan would be difficult. Confined to this one.

I can’t draw anything, and the people in the tribe don’t know it at all, because they can’t understand it just by describing it.

It’s also very difficult to do it by yourself. , because there are many things that he doesn’t understand.

For example, he is a mason or a carpenter. He definitely doesn’t know these skills. He has definitely seen pigs running if he has never eaten pork, so his painting is still very simple, as long as he draws it Just let others do it.

Yuying nodded heavily, and immediately took out the pennisetum paper and quill pen and handed them over.

Then she began to wait quietly aside, wanting to see what the hot air balloon looked like.

"Get me a pencil and an eraser. The quill is not easy to use."Su Bai said softly.

Everything in the quill pen is all the juice of the black stone nut. Once you write these things, they cannot be modified.

If you make a mistake when you draw, all your efforts will be wasted, so you still use a pencil and eraser. better

"yes."Yu Ying nodded. She found a pencil and an eraser and handed them over.

"swish swish......"

Su Bai took the pencil and eraser and began to draw the outline of the hot air balloon on the paper.

In addition, some detailed things need to be drawn, such as a basket to carry people, or a basin for holding flames, etc.

It is not difficult to draw a hot air balloon. The difficult thing is to make good use of the principle of flying into the sky.

Hot air balloons are heated air inside the balloon, which has a lower density than the cold outside air, which acts as a buoyancy force to cause the entire body to move.

It mainly uses heated air, or certain gases such as hydrogen or helium whose density is lower than the density of the air outside the balloon to create buoyant flight.

Hot air balloons control the rise and fall of the balloon by adjusting the temperature of the air in the balloon.

The basic principle of hot air balloon flight is thermal expansion and contraction, that is, when the air expands when heated, the specific gravity will become lighter and rise upward.

This operation is not difficult. All you need to do is to operate it properly. As long as one person practices a few more times, he can control the hot air balloon.

"Tap tap tap......"

Yanhua and Shalan had finished training and walked up to the second floor of the cement house from outside.

As soon as they went upstairs, they saw Su Bai drawing something seriously in front of the table, and their laughter immediately stopped.

At this time, they were relatively aware of the importance. When Wu was busy with something, they would not disturb him under any circumstances.

The beast-eared girls slowly approached the fox-eared girls, walking as quietly as possible.

Yanhua gently approached Fox-Eared Girl and asked,"What is Wu doing now? He looks so serious."

While asking, Ox-Eared Girl looked at Su Bai, the expression on her face was full of curiosity.

Usually at this time, the witch is drawing some useful things for the tribe, so she is particularly curious and doesn't know what good things it will be this time.

"Yes, are you making some weapons?"This is what Sha Lan suddenly thought of.

The cat-eared girl also envied the horned girl. That saber looked so powerful. It could cut anything easily.

So she wanted to own it too. Every time she saw the witch When I draw something, I think about weapons.

"No, Wu is drawing a hot air balloon."Yu Ying said with a smile. Because she already knew, the expression on her face was particularly happy.

"hot air balloon?"The beast-eared girls said in unison. It was also the first time for them to hear this unfamiliar word.

"Yes, it’s something that can make us fly into the sky, Wu said......."Yuying said all the words she just heard.

After the fox-eared girl finished speaking, her pink fox tail was still wagging, and it was obvious that her excitement had not faded.

"Since it is so magical, can we all fly into the sky? Yanhua asked in disbelief.

"If so that would be great, I would love to fly up to see it."Sha Lan is obviously looking forward to it.

"I don’t know, these are all said by witches, but witches have never lied to us, so they must be true."Yu Ying said seriously.

Fox-eared lady was very convinced at first, but after thinking about it, she felt that this was unrealistic.

If it weren't for growing wings or using witchcraft, it would be too difficult for ordinary people to fly into the sky. Okay.

But when I saw Wu Xin’s sworn look, I believed it again. Now when I saw Niujiao Niang’s unbelievable look, I was a little shaken.

"What the witch said should be true. The witch would never lie to us."Yanhua said seriously immediately.

Niujiao Niang can be said to trust Su Bai unconditionally, because since he came to the tribe, many things have changed for the better.

The entire tribe is also developing in a good direction. Every time he takes out The new things are very good, and they are also very good for the development of the tribe.

Or she can do it every time she says it, and she has never deceived anyone, so she is particularly convinced.

"Yes, what Wu said must be true."Shalan twitched her cat ears.

Although the cat-eared lady didn't get along with Su Bai for a long time, this period of time alone was enough to convince her.

"Why did you come here suddenly?"Yu Ying asked curiously

"Didn’t we harvest a lot of wheat before? Then Wu asked us to keep those straws. There are a lot of them now. We don’t know what we will do that time. Sha Lan said

"Yes, if we hadn't stopped them, they would have been burned, so let's come over and ask the witch what to do? Yanhua added

"Then wait until the witch painting is finished, then ask again."Yu Ying said softly..........................................
