"You also want me to do it myself?" Qian Rujun wanted to test Xiang Yuhe's adaptability. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Info also wants to know how he will react in the face of such an unopposed power.

"Princess, this is also a place where you can have a more relaxed thing to do when you are busy. ”

Obviously, Xiang Yuhe had long thought about the princess's raincoat. So he directly mentioned his plan.

Qian Rujun has never asked for privileges. If the actor thinks it is necessary for her to do it, she will not object.

"But I don't want to do it? I've been busy lately. There were a couple of helmsmen and there was no time to do it. ”

"Helmsman, I've arranged for a few friends to help with it. They also think it should be. ”

"If the princess asks, I believe there are many people who are willing to help the princess do it. ”

Qian Rujun could hear that Xiang Yuhe's meaning was all voluntary. In fact, if Qian Rujun is unwilling to do it. Most of them are willing to help her. And take it for granted.

"It's boring, it's not fun. Then you have also prepared my share of the materials, and I have to do my own part. But you have to tell us if what you're doing is effective or not, so I can arrange a classroom for you to teach. With so many people, this classroom may have to open the largest one. ”

Qian Rujun said. And write things down.

She is responsible for a lot of things, and if she doesn't write them down, she may really forget something important.

For the students of Xuetang Island, it is a great honor and pride to be able to teach what he has discovered on stage in a large classroom.

Qian Rujun is actually very curious, in this era when chemical products have not yet been available, it is actually very difficult to make something that can prevent rain.

Even if it is such a thing, it is difficult for the water to be outside through layers of resistance.

After a long time, the water will slowly seep into the clothes and cannot be used for a long time.

For them, they walk outside, and if it rains, the best thing to do is not to keep going, but to find a place where they can shelter from the wind and rain.

Set up your tent and hide in it.

It's just that it is unlikely that more than a thousand of them want to have a very large camp. Most of the mountains are very narrow.

It is estimated that the students are also discussing this issue, so the students of these schools on the island will think of making raincoats.

Even if there is rain gear, Qian Rujun is not prepared to let the students of the students still be active outside when it rains.

Because it's easy to catch a cold.

Although they are physically stronger after drinking the spiritual water, they cannot avoid the danger of illness 100%.

They don't have e-books.

When it rains, there are many wild animals that take advantage of people's rush to hunt.

For animals, they are exposed to rain for a short period of time, and for some animals it is okay. Some don't care too much about the rain.

Many people think that the rain is beautiful.

However, some people will notice that it is especially dangerous when it rains.

Even on flat land, disasters such as flooding can occur when the rain is heavy.

Of course, if there is no rain at all, a drought may occur.

Water is a necessity for us human beings, but when everything needed is in excess, it is a disaster.

The danger after the rain in the mountains, Qian Rujun is very clear.

Of course, she won't be the one who knows best.

The people who actually live in the mountains will know much better than her.

In later generations, there were many people who lived in the mountains.

There are not many people in Dahan who dare to live in the mountains. In addition to the bottom terrain factor, the most important factor is the danger.

Great Han, the number of beasts in the mountains is thousands of times more than that of humans. In the mountains, they may be hunted, not actively hunted.

Most of the people took refuge in the mountains to escape the war. But they did not dare to live alone in the mountains, but in a group of people in small basins between the mountains.

Form an artificial space.

The dangers in the mountains may even extend to flat ground, causing flooding or slipping. Flooded villages on flat ground.

In many places, the flooding is due to the water from the mountains.

The water on the mountain collects the ground and brings kinetic energy, which washes the land on both sides, and in this process, the power of water is unstoppable.

If human beings had not blocked it with something hard, it is likely that the land would have been washed away, and the houses that lived on the land would have been washed away, and you would have suffered the loss if you were human.

Not to mention being in the mountains, the ground under your feet may suddenly lose solid energy due to excessive water content, and liquefy and collapse directly.

You can't defend against it, even if you run fast enough, but humans must have a reaction force to jump.

The land has been lost, how can it provide you with enough reaction force to jump out of the way?

Speaking of which, all kinds of dangers in the mountains will be multiplied, and the dangers brought by increasing the water body are even more numerous.

Landslides and landslides are almost impossible to avoid the effects of water, and unless the earth brings another kind of kinetic energy, which is an earthquake, in most cases, these things are related to water.

Even if you're wearing rain gear, how can you avoid these dangers?

Qian Rujun knew that he couldn't stop Xiang Yuhe's creativity at this time. Because students are creative, they must be given room to express themselves, otherwise it will hinder their lives.

Qian Rujun was still very patient to listen to Xiang Yuhe explain his rain gear.

For Qian Rujun, Xiang Yuhe's rain gear is actually not too trendy.

The concept he uses is to change the material, to make use of the material.

In other words, they are looking for clothing that can protect against water.

Many people didn't expect that silk fabrics could actually be waterproof, but Xiang Yuhe noticed it.

Qian Rujun once paid attention to this special fabric of silk. Because in later generations, silk could even be made into body armor.

Through different weaving methods, silk can express different textures.

It's a pity that Xiang Yuhe didn't have too good conditions on the boat.

Because there is no special weaver here who can help him experiment with different weaving methods, and Xiang Yuhe has not yet realized this.

He used other materials to assist in the production of waterproof special clothing.

Even in later generations, materials science itself is a part of science and technology, and can even make the material of this world change dramatically.

The improvement of silk weaving methods is actually a part of material science, and most of the weaving methods in this era are the continuation of the previous generation and the development of a new weaving method, just for the needs of the grain, so that the silk becomes more beautiful.

A large number of things have been invented in more than a hundred years.

It's not that the previous accumulation was not enough, but that there was not so much manpower input.
