I was a village chief in a primitive society

Chapter 432: Isn’t it because you are afraid of heights? (3 more, please customize)

The expressions of Aier and the others are pretty good, because they can often fly into the sky.

I can often feel the feeling of being in the sky, and I don’t know how many times I have seen the ground from below.

So this time when they flew into the sky, their expressions were not exaggerated.

But there will still be a shock, after all, this is the first time I have seen a hot air balloon.

They didn't even expect that a hot air balloon made of animal skin could fly into the sky, and it also relied on flames to fly into the sky. This was a bit incredible.

This was the reason for their shock. As for the beautiful scenery below, they were not surprised at all.

"I didn’t expect this thing to fly without wings."Ai'er said in surprise.

Butterfly Girl flew out of the hot air balloon and planned to observe the hot air balloon 360 degrees.

"Phew! Phew!"

The butterfly girl flapped her beautiful purple wings and flew out, and began to observe around the hot air balloon. She flew up to the top and down to the bottom of the basket, watching carefully, and sometimes she flew to the side of the flame to watch.

Just. Like a curious baby, he looked at the hot air balloon up and down, and poked the big balloon with his finger from time to time.

I found that the hardness of the big balloon was quite hard. At first, I found that I couldn't poke it in, but then I poked it hard and it got a little dented. That's all

"It's really amazing."Ai'er kept mumbling to herself.

Butterfly Girl returned to the hot air balloon with curiosity, her face full of questions.

Okay.

"How about it? Did you see anything different? Chengshi asked why.

Originally, the boy wanted to fly out and have a look, but he thought that he must protect the safety of the good witch first, so he suppressed his curiosity.

"Fly out and take a look, I'm here."Ai'er pushed the other party. Instead of talking to herself for a long time, it was better for the other party to take a look.

Yanhua looked up at the big brazier and wondered:"Witch, why can you fly with the help of flames?"

The Niujiao Niang has had this doubt for a long time. She wanted to ask the question before she even took off from the bottom. She was still lighting the fire.

But she didn't know what she wanted to do at the time. It wasn't until the balloon soared that she suddenly realized it.

"Yes, yes, Wu, won't these flames burn the hot air balloon?"Yu Ying asked worriedly.

The fox-eared girl was curious about something different from the others. She was curious about whether the hot air balloon was safe.

Unlike the horned girl, she didn't have the time to worry about whether the hot air balloon was safe. I just think this hot air balloon is so fun

"Probably not? These flames are so far away from the hot air balloon. Sha Lan guessed.

The cat-eared girl was also curious about this point, but a hot air balloon cannot fly without those burning flames. She still knew this.

"This is called thermal expansion and contraction, and the heat emitted by the flame is used to make the hot air balloon fly."Su Bai explained simply and crudely.

In fact, hot air balloon flight is based on the principle that the density of hot air is smaller than that of cold air, and the same volume of hot air is lighter than cold air, thus generating buoyancy.

The flame heats the air in the balloon, and when the air is affected by After thermal expansion, the specific gravity will become lighter.

The hot air will rise above the cold air. Hot air is lighter than cold air because the mass of hot air per unit volume is smaller, making it lighter and generating buoyancy heat, which can lift the balloon into the air.

Now, if you tell girls this principle, they still don’t understand it. It’s different if you tell it to a blond girl.

They will definitely understand it faster, and they will also want to do an experiment.

"don't know."Yanhua said without hesitation, this is indeed a bit difficult for her.

She only knows how to fight with weapons, but she still doesn't understand the hot air and cold air.

"I probably know something about it. It should be that when the flame is burning, it heats the air, and then the hot air balloon flies up. Wu, right? Sha Lan asked tentatively.

The cat-eared girl also thought about it for a while before coming to this conclusion, but she didn't know if this conclusion was correct.

"That's exactly what it is."Su Bai nodded with satisfaction, but he slightly underestimated the cat-eared lady.

"Wu, then this flame really won’t burn the hot air balloon, right?"Yuying is still very worried.

"Don't worry, the flame is still some distance away from the hot air balloon, and the flame is not very big. I will light the hot air balloon and we will be safe."Su Bai put his hand on the fox-eared girl's hand.

He saw that the other party was very nervous, and the pink fox tail drooped involuntarily.

Yuying's small hand was suddenly covered by a pair of big hands, and her heartbeat instantly It began to speed up.

The originally worried heart began to calm down, and she didn't look so scared anymore.

She took a deep breath, nodded heavily and said:"Yeah, I believe in witches.""

The little hand of the fox-eared girl was pinched by the big hand. She felt a sense of security that she had never experienced before, but at the same time she was a little shy. Her little face immediately turned red. She didn't dare to look up at Su Bai, and she had no intention of watching the hot air balloon. The beautiful scenery below, all the attention was on the big hand. The pink fox tail that was originally drooping began to stand up slowly, and then swayed involuntarily, and the overall look was in a good mood.

Sha Lan saw this scene, Suddenly she felt strange in her heart, and she really wanted to be treated like this.

But she suddenly shook her head crazily, thinking that this idea was too incredible.

How could she have such an idea? It was really too bold, The other party is a witch, why do you think so?

Yanhua was very strange when he saw the cat-eared girl, and asked doubtfully:"Alan, what's wrong with you? Is it uncomfortable?"

The horned lady didn't know what the other party was doing, but she only knew that the other party's face was suddenly so red.

"What happened to Alan? Is it uncomfortable to fly too high?"Su Bai also turned around and greeted.

After all, hot air balloons fly in the sky. I wonder if the girl is not used to flying so high, or maybe the other party is afraid of heights.

Sha Lan immediately stood up straight and restrained himself. He shook his head emotionally and said:"No, Wu, it doesn't matter to me."

The cat-eared girl has been blaming herself in her heart, why do she suddenly have so many random ideas?

"Just be fine, remember to tell me if you have anything."Su Bai said seriously.

If the girl doesn't have any fear of heights, then she should let her go down in time.

Although fear of heights is not a serious disease, the hot air balloon will fly higher and higher. If the girl is at high altitude, I'm scared, but I'm a little out of control

"Wu was worried."Sha Lan immediately lowered his head.

"It's okay. If any of you feel uncomfortable, remember to tell me."Su Bai glanced around and said

"yes."Everyone said in unison.........................................
