Du Chuan felt that Bi Fang's eyes seemed to be looking at a fool, his face was stiff like an ice cube, dense blood filled the whites of his eyes, and his heart seemed to be dripping with blood.

"You're murder!"

"What nonsense?" Bi Fang was furious, pointed to the sea of quicksand in front of him, and said angrily, "Do you think I know that this is quicksand? Didn't I fall in on that too? ”

"Do you see any difference between this desert and the previous ones? Yes? ”

Du Chuan, who was asked rhetorically, breathed sluggishly.

Yes, even if the other party did it on purpose, what evidence can he have to prove it?

Under the dark sky, all deserts are the same gray-black, what difference is there?

Du Chuan thought about it desperately, and suddenly remembered the last sentence that Bi Fang said just now, and pointed at Bi Fang's nose and scolded.

"Then why do you say welcome to hell?"

"I wanted to intimidate the audience, but I never thought that this place was really quicksand." Bi Fang looked at Du Chuan, who was constantly sinking, and was still not in a hurry.

Bi Fang's acting skills are so realistic that Du Chuan couldn't tell the truth for a while, and just when he wanted to speak, Pan Wei on the side couldn't stand it.

"Fang Shen, help me! Please, save me! I don't want to die, I really don't want to die! ”

"I swear, I swear I won't rub your heat in the future, please, please!"

"I'm old and young, I can't die yet, it's all him! It's all signed by him, and I'm dizzy! ”

Under the huge stimulation, Pan Wei's tears collapsed like blood, his snot mixed with vomit slid down the corners of his mouth, and his breath was like a person who was about to freeze to death spitting out faint white vapor in the depths of the cold night, but he still blamed Du Chuan like crazy.

Severe sunburn and water poisoning, under such a huge stimulus, he has not fainted and his will to survive is amazing.

Bi Fang saved so many people last time, so he will come to save him this time, right?

"It's not that I don't want to, but you are so far away, how can I save it?" Bi Fang spread his hands, indicating that he was really powerless.

The other party was sent directly after the collapse of the sand dune, at least a few dozen meters away from him, there are no trees and no ropes here, how to save them.

What?

Clothes torn off as rope? Where did he get so much effort to tear his clothes?

No, it doesn't.

Bi Fang shook his head in disappointment, he also wanted to save it, but there was really nothing he could do!

And the sailors who have been watching have long been dumbfounded, starting from the collapse of the sand dunes, they can no longer understand the development of things.

Is this going to die?

Can it be saved?

Many people's impressions of quicksand come from various films, and in their perception, quicksand is a big monster that can suck people into a bottomless pit.

Once people are trapped in it, they can't extricate themselves and can only watch as the trapped people are swallowed by the sand in an instant.

[It's a little too much......]

[What? Fang Shen didn't mean it, didn't you see that he also fell into it just now? A little brain, okay? 】

[They deserve it, they want to follow, they don't have their lives, who is to blame? Early Death and Early Superbirth]

[Upstairs passed]

[I don't think it's over, it's a big joy right now! 】

[The old party won't get into trouble, right? ] Don't save when you die]

[How can I save if I can't save it? ] Don't you see that it's so far away? 】

When the water friends were arguing, Du Chuan and the others had already buried themselves in their chests, and their breathing began to be difficult.

Pan Wei was even more sobbing, fear was like a devil's claw, holding his heart and drawing blood marks on it.

He just felt a heat in his crotch.

The moisture of the surrounding sand increased.

In the panic, Du Chuan couldn't think carefully about whether Bi Fang did it on purpose, and he didn't even pay attention to Pan Wei's face-turning, he just wanted to survive now!

Grabbing the car on the side, Du Chuan wanted to pull himself up with the help of reaction force, but it was useless, and the terrifying suction came from his lower body.

What to do?

Du Chuan panicked, really panicked.

He had never thought that he might take his life again just by rubbing the heat!

Wrapped in the hot quicksand, Du Chuan felt as if he was about to be cooked, and large pieces of sweat were dripping.

"Remember, the more you struggle, the faster you sink, and if you don't move, it becomes very slow, and besides, this is wet sand, as long as you are honest, it can't sink." Bi Fang pointed to the fainting fat man, very concerned.

Sure enough, among the four people, only the fat man who didn't move much was still stuck in the sand, and the sand only reached his buttocks, and the whole person barely sank.

Seeing this scene, Du Chuan and the others didn't dare to move all of a sudden.

"If you're lucky, this is wet sand, not dry sand, and wet sand is in principle just sand that has been infiltrated with water, and due to the reduced friction between the sand particles, a semi-liquid, hard-to-bear sand-water mixture is formed."

Bi Fang grabbed a handful of quicksand, held it in his hand and squeezed it hard, and the audience could clearly see that the sand was clumped together like plasticine.

It's like the mud I used to do when I was a kid.

"In this kind of quicksand, if you think that you can loosen the sand around your body by shaking it, so that your limbs can be pulled out of the quicksand, you are very wrong, this kind of movement can only accelerate the deposition of the clay, increase the stickiness of the quicksand, and the person who struggles indiscriminately will only sink deeper and deeper."

"To escape from this quicksand, the trapped person has to move their feet gently so that the water and sand can penetrate as much as possible into the squeezed out vacuum area, which will relieve the pressure on the trapped person's body and allow the sand to slowly loosen."

"At the same time, try to keep your limbs as far apart as possible, because the greater the surface area of the sand, the more buoyancy you get. As long as the trapped person has enough patience and gentle enough movements, they can slowly get out of the trap. ”

Bi Fang said very seriously, Du Chuan and the others listened very carefully, and they couldn't wait to put their ears on his face, but the distance was too far, and some words were blurred.

But several people also grasped the key words, moved slowly, and slowly got out of trouble.

"In fluid mechanics, quicksand is classified as an expansive fluid, which means that the greater the shear force, the more viscous the quicksand will resist the shear movement. The researchers calculated that dragging one of the trapped person's feet at a rate of one centimeter per second would require about 100,000 Newtons, about the same force as lifting a medium-sized car. ”

"So unless you have a crane to help, it's hard to pull someone out of the quicksand all at once. However, according to the calculation of this strength, if it is pulled stiffly, then the human body will have been torn off before the quicksand 'lets go'. ”

Rip-off?

Many viewers were taken aback when they heard this word.

[, so terrifying? 】

[Hand tearing devils? 】

[Fluid mechanics is out, let me see, what else does Fang Shen can't do, meteorology, geography, biology...... emmm】

[Terrifying! I was surprised to find that Fang Shen could do anything! 】

[But Fang Shen climbed so fast just now, I didn't see anything clearly, why did I come up? ] 】

"Because I react quickly, wet sand is slow quicksand, as long as I don't sink deeply, move quickly, and judge the direction accurately, I can escape."

Bi Fang knew that this was a piece of quicksand, of course, he had been prepared, and now his reaction was as high as 12, which was already stronger than ordinary people.

"But at that time, many people's attention may not have been on my side at that time, if I didn't see it, I could wait for my survival and go and watch the edited video."

Bi Fang is not only talking to the audience, but also teaching Du Chuan and others how to escape.

Severe sunburn, water poisoning...... Bi Fang touched the hot sand, well, now add to that the low temperature burns, difficulty breathing, wound infection and dehydration.

After this set of processes, the probability of death should not be large.

After all, I'm not a demon myself.

There is no life-and-death feud between the two sides, it's just a group of shameless people who come to rub the heat, there is no need to kill them directly, now they can jump out and kill chickens to show monkeys.

Let those who want to rub his heat next time weigh their own weight.
