Ballistic Silence of Special Years

Jumping into the water, the icy water instantly surrounded him.

The water here is not deep, only more than one meter, and a person standing in the water is only submerged to the abdomen, not to the chest.

When I came here, I was in a car, and there was some mountain wind. My body was cold. When I got into the water, my lower body was in the water, and my upper body was soaked by the splashing water. At first, I didn’t think there was any problem, but after a while, a mountain wind After blowing, Li Zheng couldn't help but trembled.

Fatty Wei next to him shook his huge head and said, "What kind of water is this! Why is it so cold?"

Li Zheng said: "This is an irrigation canal for agricultural purposes. The water is naturally from the river or the reservoir. Of course it is cold."

Actually they were all wrong.

If it is river water or reservoir water, it is not so cold.

This is a serious landscape.

Flying down from a waterfall on the mountain, a large pool of water rushed out at the foot of the mountain, and then led here through irrigation canals.

When everyone was in the water, Tong Zhi and Yilian several other instructors patrolled along the canal, and then began to issue new orders.

"It's all there, squat down!"

Everyone can only squat down.

But once squatting down, everyone immediately found that something was wrong.

The water was not deep at first, but after squatting down, the water directly covered the neck, and when it reached the chin, some short ones directly soaked the mouth, so they had to close their mouths tightly and only breathe through their noses.

After soaking for about ten minutes, Tong Zhi looked at the stopwatch, felt that the time was almost up, and gave another command: "Stand up!"

After standing up for about 10 minutes, Tong Zhi asked everyone to squat down again.

After about ten minutes, let everyone get up again.

At first, everyone thought Tong Motou was boring and deliberately torturing the big guy.

The result is slowly getting better.

The water soaked his body and clothes, and when he stood up again, Li Zheng found that his body temperature was obviously dropping rapidly.

The principle is actually very simple. If you simply soak in the water without moving and adapt to the temperature of the water, the human body will not feel too uncomfortable.

But once he gets up, the wind in the mountains blows over his drenched upper body, quickly taking away the heat from his body like a radiator.

After coming and going, Tong Motou's purpose is to let everyone lose their body temperature in the shortest time.

Rapid loss of body temperature can lead to hypothermia.

Li Zheng knew this very well.

He had experienced this feeling before under the ruins.

So he has inquired about this symptom many times afterwards.

He knows how powerful it is.

Because the normal body temperature of the human body is 36.5–37.5 degrees Celsius, hypothermia can be divided into three stages according to its severity.

The first stage is relatively mild hypothermia, and the body temperature drops to 1-2 degrees lower than normal body temperature.During this stage, the human body trembles, the hands become numb, and complex movements cannot be performed.Vasoconstriction of distal extremities reduces heat loss.Breathe fast and shallow."Goosebumps" appear on the skin and try to make the hairs stand on end for insulation.

This response is limited due to the lack of hair on humans, but is more effective in other species.

So, a person with hypothermia may feel fatigued and have abdominal pains, and at the same time find themselves strangely warmed.

If you think that you have survived this time and have prevented the danger of body temperature loss by shaking your body and the like, it is a big mistake.

In fact, this is a sign that hypothermia has progressed to the second stage.

When the condition of hypothermia enters the second stage, the body temperature will drop to 2-4 degrees lower than the normal body temperature.The shaking of the body is more violent, the muscle incoordination is more obvious, and then the movement is obviously felt more sluggish and difficult, with stumbling steps and disorientation, although the patient may remain alert.

The human body responds to this hypothermia in a defensive response, and the superficial blood vessels continue to constrict to keep vital organs warm.The patient is pale and the lips, ears, fingers, and toes may turn blue.

If the hypothermia has not been treated or effectively stopped, it will enter the third stage of terror.

By this time the body temperature has dropped below about 32 degrees, and the shaking of the body has usually stopped.Speech difficulties began to appear, slow thinking, and memory problems began.

The most frightening time is that the hypothermia person himself will lose the ability to save himself. Usually, the hands cannot be used, the standing is unstable, and the cell metabolism stops.

Finally, hypothermia will enter a fatal stage. When the body temperature drops below 30 degrees, the exposed skin turns blue and swells, muscle coordination is almost completely lost, walking is almost impossible, speech is incoherent, actions are irrational, and pulse and breathing are obvious. Slows down, but ventricular tachycardia and atrial fibrillation may occur, major organs in the body stop working, and clinical death is declared.

"This is to punish us to death!"

Two hours later, Fatty Wei's upper and lower teeth began to fight and rattle.

"Squat down!"

Tong Zhi issued another password.

This time, the entire team slowed down.

Many people no longer just squat down like they did at the beginning, hesitating there, saying that they are unwilling to soak their whole body in the water again.

Because of being blown by the mountain wind, the person was shivering, and suddenly soaked in the water again. The temperature in the water seemed to be a little higher than that above the water surface, and the moment he squatted down, he would feel a sense of warmth.

But this kind of warmth doesn't last long, and I have to stand up again after a while, and the mountain wind will make people feel colder and more uncomfortable.

Repeatedly squatting and standing up in the water is simply a kind of torture.

It is already early morning.

The temperature in the mountains dropped rapidly.

The temperature difference between day and night here can reach nearly twenty degrees.

There is still fog in the mountains at night, that taste...

Simply sour!
"Wang Fang! Why don't you squat down! Squat down! Squat down now!"

Li Zheng turned his head and looked at the place where the sound came from. It was about ten meters upstream from him, and it might be soldiers from the second row.

The instructor's flashlight shone on Wang Fang who was unwilling to squat down.

Wang Fang leaned against the wall, a little at a loss.

"Squat down!"

The instructor yelled.

Li Zheng saw clearly that it was the instructor named Jin Weiheng, the one who came from the Thunder God commando.

"I'll give you five seconds, and if you don't squat down, you will be disqualified!"

Wang Fang was leaning against the wall of the canal. Under the light of the flashlight, Li Zheng saw that his face was full of panic, and his cheeks were twitching, as if trembling.

"I don't practice anymore! I want to quit!"

Finally, he chose to give up...

Everyone's heart sank.

Li Zheng had never seen anyone voluntarily withdraw from the training camp before.

Wang Fang was the first person he witnessed to abandon Devil Zhou.

This took a lot of psychological impact on him. He was desperately persevering, while some of the other comrades in a canal chose to quit.

He was a little confused for a moment.

What am I holding on to?
Seeing that Wang Fang had chosen to give up, Jin Weiheng reached out and pulled him up from the ditch.

Wang Fang was obviously so cold that he showed some symptoms of hypothermia, and he was dragged to the cement road for a long time without getting up.

Jin Wei-Heng pointed to the security car not far away: "Go there to get a thermal blanket, and ask the monitor there for a cup of hot milk."

Wang Fang lay on the ground without moving.

Not long after, he suddenly covered his eyes with one hand and began to cry.
