Reborn in that autumn

Watching my brother and the others walking forward, they went to the place where they were standing just now.

Ye Qiu stopped paying attention to them and instead started communicating with Ao Shijie in the space.

"Uncle Aoxue, have you ever encountered such a mechanism? What kind of mechanism is this?" Ye Qiu asked Ao Shijie.

Ao Shijie, who was eating space snacks, replied: "I don't know, I haven't seen it. Speaking of which, I haven't encountered it either."

"Then since you don't know and have never seen this kind of mechanism, of course you can't know how to get past it? That's troublesome. How should we get past it?" Ye Qiu said helplessly after hearing this.

"Then what you are saying now is that there are always more solutions than difficulties. The solutions are all figured out. Since they can design like this, there must be a way in the past, but we have not found it."

"Don't be discouraged? There are so many of us, we will always find a way."

"What's more, a smart guy like me can't think of a solution."

"What's more, you have such a big library here. I'll go in there and study it first, while you think about it yourself first," Ao Shijie said.

Ye Qiu replied: "Okay"

"This thing looks like quicksand!"

"I seem to have read it in a book. If you think about it slowly and carefully, you will definitely be able to think of it."

At this time, Li Zichen came back and said, "What quicksand."

Only then did Ye Qiu realize that he had been too absorbed in his thoughts just now. He spoke up and explained: "Hey, I've seen it in a novel. It's like this. It's full of sand down there."

"Quicksand is basically regular sand, except that the water in this sand has been saturated, so the friction between the sand grains is reduced. The resulting sand is a mushy mixture of sand and water that can no longer hold Any weight.”

"Just like you didn't struggle when you fell just now, I easily pulled you up."

"If you step into quicksand, it won't suck you in. However, if you move around in it, you will sink deeper and deeper. He made me want to see you, so I won't come out. Fortunately, you are very calm."

Quicksand is an interesting natural phenomenon - it's actually solid ground that has liquefied due to being oversaturated with water. "Flow" means that sand moves very easily in this semi-fluid state.Quicksand is not a special type of soil; it is usually sand or another type of granular soil.Quicksand is nothing more than a mushy mixture of sand and water - the sand actually floats on the water.

"When the water in a loose sand belt reaches saturation, ordinary sand will tumble up, forming quicksand. If the water captured by the sand cannot escape from it, liquefied soil will form, and the liquefied soil can no longer bear the weight. There are two ways It can increase the tumbling degree of sand, eventually forming quicksand.”

“Flowing groundwater—the force created by the upward flow of water overcomes gravity and makes sand particles more buoyant.”

"Then what if I was accidentally sucked into the quicksand because you didn't react in time? Where will we float to?" Li Zichen asked after hearing this.

"Generally, quicksand will suck people up to the waist and stop, and people swallowed by quicksand may also be washed to other places along the current. In fact, quicksand cannot completely engulf people, because the density of the human body is smaller than that of sand. Quicksand will only make people sink slowly, and they will stop after sinking to the waist level."

"Therefore, if you are accidentally swallowed by the quicksand, you should stay calm when being sucked by the quicksand. Try to spread your limbs and lie back to increase the contact area between the body and the quicksand. Then slowly move to a safe area and use Escape from the quicksand area by crawling or sliding." Ye Qiu thought of the words in the book and explained.

"There is a difference between quicksand and swamp, but anyone who has been swallowed can be found. But the place where they may be found will be different."

"Because the formation of quicksand is inseparable from groundwater, and groundwater is flowing, so when a person is completely swallowed by quicksand, it will also flow and may be swept to other places along the current."

"But a swamp is different. A swamp is just a big mud pit, filled with silt. So if it is swallowed by the swamp, it will only sink to the bottom and not flow."

"" Just like in the desert, quicksand is sand that flows like water, but quicksand is not really like water.The reason for the formation of quicksand is that the groundwater in the desert rises up and liquefies the sand, so it can flow.Under normal circumstances, as long as a person falls into quicksand and does not stir and struggle, he will not be swallowed up quickly.Because the density of quicksand is less than the density of people. "

"So if an object is less dense than quicksand, it will float on quicksand. And some people have conducted research. After an object sinks into quicksand, the rate of sinking is also related to the density of the object itself. Things with high density will sink in quicksand. The faster the speed, the slower the density is lower than the density of quicksand. The human body is lower than the density of quicksand, so people will not be catastrophic after falling into quicksand. But there is one thing to note, that is, do not struggle , the more you struggle, the more dangerous it is. You should lie on your back to increase the force-bearing area, so that you can save yourself, because in quicksand, people will stop when they sink to the waist. The same is true for swamps. In fact, swamps are more dangerous than quicksand. . Because after entering a swamp, a person will continue to sink. In order to reduce the sinking of the body, one should also lie on his back to increase the stress-bearing area and have time to wait for rescue."

When Li Zichen heard this, he said to several people: "Listen carefully to Teacher Ye's words and keep them in mind. When you meet in the future, you may be able to save your own life. These are all wealth and can save your life at critical moments."

"Yes, I understand." Several people replied.

Ye Qiu smiled and replied: "How can I be called a teacher? I just saw it in a book. Maybe you have seen it before, but you have forgotten or studied it."

"Your knowledge is very valuable to us. Some of us have barely studied for a few days. Most of us rely on our own experience."

"But what kind of quicksand is this? We have never been exposed to it, so how can we know how to escape from it? Speaking of which, we have to thank you for letting us know so much. Maybe one day in the future, we will encounter it during our mission. "A few people among the security guards said to me one sentence at a time.

"You will be our teacher Xiaoye for a while today and tell us more. We are willing to listen. Maybe we will figure out how to escape the danger while we are chatting, and we will go over." One of the security guards said. "

"Okay then! If you want to listen, I can continue." Ye Qiu replied.
