I was a village chief in a primitive society

Luzi came to Yong'an Building after class. Because she was holding an umbrella, she didn't get wet.

As soon as she came in, she bowed very politely and asked,"What does the witch want from me?"

"I want to know something about your other continent."Su Bai asked.

I asked briefly last time, but I didn't ask in detail because at that time, I didn't have much desire for another continent.

But I couldn't bear it. I have to go through three months every year. It’s the rainy season around here, which is really a bit inconvenient.

Since it doesn’t rain on another continent, would you consider spending it there in the rainy season next year or in the future?

"The witch is talking about our Shanxiang tribe, right? The demand for water there is very large, which is completely different from ours. Luzi thought of her tribe."There aren't many trees over there, so it can be said that there are completely two different looks.""

"Is everything filled with sand? There are very few trees and water sources, right?"Su Bai asked.

After hearing it last time, he felt that the other continent was very much like a desert, and this continent was a forest.

But he was not very sure at the time, because he remembered that in the primitive era, the desert did not seem to exist. In terms of natural conditions, dry climate is an important condition for the formation of large-scale deserts.

In dry areas, in addition to rocks weathered into debris, there is also a large amount of silt and stones brought by dry rivers.

There is a lack of When covered with plants, once strong winds blow, a large amount of sand on the ground will be lifted up.

When the wind weakens or encounters obstacles, large areas of sand and dust will accumulate to become deserts. Large areas of desert are often scattered in the Dry areas or basins with relatively low terrain.

Su Bai has some knowledge in this area. Large-scale deserts on the earth are mainly distributed in two dry areas.

One is the northwest desert area of ​​Su Bai country, which is far away from the ocean. , there are also mountains blocking the way, making it difficult for the moist ocean air to reach.

At the same time, rainfall is particularly scarce, which contributes to the formation of deserts.

The second is the Sahara Desert in a certain African region, where the air pressure is high, the weather and wind direction are relatively stable, dry winds blow all year round, and rainfall Scarce, deserts gradually formed.

This is not just one of the reasons. There are also human factors in the formation of deserts.

Due to human deforestation, overgrazing and blind land reclamation, as well as local wars that destroyed water conservancy facilities in arid areas, All these have accelerated the process of desertification.

For a long time, due to human beings' reckless indiscriminate cultivation, deforestation, and overgrazing, the ecological balance of the sandy area has been catastrophically damaged. The harm of wind and sand has become more and more serious, forming a disaster model , overgrazing (including overcrowding and deforestation) - wind erosion - desertification.

After Su Bai's very strict analysis, he felt that there should be no such thing as a desert at this time, so he overturned the idea that another continent was a desert..

But now when I hear Luzi say this, I suddenly feel that another continent is very much like a desert.

"Wu, what is a desert?"Luzi doesn't know what a desert is.

"To put it simply, there is sand everywhere, as far as the eye can see."

Su Bai took a sip of tea."That means you don't have the concept of soil. There is sand everywhere that will sink if you step on it."

He could only think of such a simple explanation. Do you want to explain to the other party a lot about the formation of the desert?

It would be a bit too old-fashioned, and it would also make people incomprehensible.

"It's almost like this. Most of the tribes are in places with trees, but these places are very few, so we often have wars."

Luzi thought of some sad things."Our tribe died in such a war, and that's why I came here."

"You are very short of water over there, right? What if we take our water over there and change it? Do you think we can get the resources we want?"Su Bai asked.

Sometimes you can't find something in the virgin forest, such as various ores.

There are more ores in the desert, or there are some What about other foods or fruits and vegetables!

"It's definitely possible. The demand for water there is very big. If Wu Na goes there to exchange water, everyone will definitely be vying for it. Luzi said without hesitation

"In this case, if you were asked to lead the way, would you know how to go back?"Su Bai asked.

He was thinking that he could not spend all his time on this continent, because all the available resources in the surrounding areas have been used up.

Now he just has to wait for the surrounding resources to slowly pick up. Now he is in a state of In the development stage, even if you want to move faster, there is nothing you can do.

So he wants to set his sights on another continent. This is also to make the Yanlong tribe urbanize faster.

"I definitely won’t remember much when I walk back, but if I fly in a hot air balloon, maybe I can still remember it." Luzi said.

Although the girl's expression looked calm, she was already very, very excited inside.

If she hadn't been in front of the witch now, she would have jumped up with excitement. Now she still needs to restrain her image.

"Recently I have been thinking about some new means of transportation, maybe not using a hot air balloon. After all, this thing cannot guarantee your 100% safety."Su Bai explained.

Yes, this is an idea he has been thinking about recently. Hot air balloons alone are definitely not enough.

He originally wanted to directly create airships or airplanes like other novels.

But he was helpless in his mind. There are ideas in it, but there are not enough materials, so there is no way to complete the ideas in his mind.

In fact, the main material of the airship is the steam engine, which the Yanlong tribe already has, but another material is also very important, that is The exterior material of the airship.

If you simply use iron ore to refine the iron, and then use the iron to make the outer iron sheet, the entire airship will be very heavy. Let alone whether it can fly up, the entire airship The safety cannot be guaranteed.

Therefore, a brand new material must be developed, which must be very thin and durable.

"No problem at all. Whenever the wizard needs me, I will be ready. Luzi said happily.

Although there was a smile on her face, her body still stood very straight, without any intention of overstepping the rules.

"You go back first and I'll call you when I'm ready."Su Bai waved his hand.

He thought it was time to prepare a new means of transportation. This would definitely surprise the people of the tribe..........................................
