"When the human body is stimulated by cold water, the blood circulation and metabolism of the whole body will be strengthened, the blood vessels of the skin will shrink sharply, and a lot of blood will be quickly sucked into the internal organs and deep tissues. ”

"If this situation occurs suddenly without adequate preparation, the brain cannot adapt to such a rapid return of blood, and it is easy to produce a temporary loss of consciousness or even fainting directly!"

"This is also one of the important reasons why the mortality rate of drowning in winter is several times higher than that in summer, so this kid should be physiologically prepared now!"

Chen Xu explained a few words.

After a while, Park Yiming seemed to be finally ready.

Then, with a sack in one hand and a billiard cue in the other, he began to slowly step his feet into the river.

Because it is now more than two o'clock in the afternoon, according to Xu Ye's consistent statement, it is the hottest time of the day.

But even so, the temperature of this river does not rise too much, because the specific heat capacity of water is greater than that of soil, at least not more than seven or eight degrees!

Therefore, the moment Park Yiming's left foot touched the surface of the water, he felt a strong cold and stimulating feeling, just like acupuncture, which instantly numbed his entire foot.

"Holy!"

Park Yiming couldn't help but gasp, he was originally a southerner, not hardy, and when he was training in the army, he also majored in jungle reconnaissance, and he rarely received snow training.

For the experience of dealing with the glacier, he is definitely not as much as Liu Gang.

Still, he gritted his teeth and stepped his other foot in.

Then, you can see that Pu Yiming, who was shivering, holding a billiard cue and carrying a sack on his back, was taking a big breath step by step, desperately inhaling, like an old man with an old man, slowly walking towards the other side of the river.

It's also a shame that he has a billiard cue in his hand as a crutch.

Otherwise, with his current trembling state, sooner or later he would have to fall into the river!

When Chen Xu saw this scene, he couldn't help but want to laugh.

He remembered that when he watched the video of "Survival in the Wilderness" in his last life, Bei Ye was in the ice and snow, and there was a clip of him taking off his clothes and throwing them into his bag and swimming over.

To put it bluntly, Park Yiming and Pei Ye's method is the same, in the case of poor fire conditions, they are the first to protect the dryness of the clothes.

But what is easier for Bei Ye than Park Yiming is that his backpack is waterproof, so he can swim over with confidence and boldness.

But Park Yiming can't, the sack is not waterproof at all, so he can only walk over step by step.

Compared to the two, it is definitely faster and easier to swim, and there is no need to think about whether it will slip suddenly.

At this time, Park Yiming had already walked to the middle of the river, and the height of the water level also overflowed his waist and began to approach his stomach.

At this time, his core body temperature has dropped below 35.9 degrees, and it is still decreasing.

The audience watched him breathe several times with every step he took, some distressed, and some happy:

"666, this kid is not afraid of freezing little JJ!"

"According to the principle of heat expansion and cold contraction, he will disappear there at least 3CM or more!"

"Hahaha, for the sake of 1 million, don't freeze your balls!"

"The worst thing is not this, but the eggs are frozen, and the 1 million is not yours!"

"I'm starting to wonder if Xu Ye deliberately picked this river......"

Looking at the barrage of "ridicule", Chen Xu's face did not change, but he secretly held back a smile in his heart.

To be honest, when he first chose Siberia, he really didn't expect that this river would bring such great difficulties.

At this time, Park Yiming finally walked to the shore, threw the sack ashore, and then crawled frantically towards the shore.

Looking at his appearance, he was obviously frozen in the water!

After going ashore, Park Yiming knelt directly on the ground, he wanted to untie the rope at the mouth of the sack quickly, but because his body was already trembling very severely, even his upper and lower teeth were constantly "clicking" to fight.

Therefore, his two hands could not be controlled at all, but at the mouth of the rope, they shook vigorously.

"I, I, I...... Damn!"

Pu Yiming shook his teeth, took a sip, and then felt ruthless in his heart, and controlled the two hands together.

Then, he began to rub his hands up and down.

"Friction heat generation is a good way to quickly raise the temperature in a short period of time, temporarily relieving the constriction of the capillaries in the hands and the tension of the muscles!"

Chen Xu watched Park Yiming's movements and nodded.

After a while, his hands were much better, and after untying the sack, he quickly put on the clothes inside.

After all the wraps were neatly wrapped, Park Yiming began to act like a madman, constantly doing high jumps, push-ups and so on on the snow.

Many old viewers are brushing the "burpees" that Xu Ye once demonstrated, because that action, whether it is to increase heart rate, blood flow rate, or heat production, is the fastest.

But obviously, Park Yiming will not do this.

However, with dry clothes, even with some ordinary exercise, he quickly raised his core body temperature.

After resting for a while, Park Yiming also began to continue on his way.

Due to physical illness, Wang Chunliang was the last to reach the river.

However, fortunately, he was the one in the lowest reaches of the river among all the participants, even below Lu Xiaoman.

The advantage is that the river is not turbulent and the water level is shallow, so you can easily see the rocks and sediment at the bottom

Chen Xu knew that the water level could only reach the calf at most.

However, the lower reaches are the widest stretches of the entire river basin.

Therefore, the width of this river that Wang Chunliang encountered has exceeded 15 meters away!

After being sick for a day, after seeing this river, he was so excited that he hurriedly got up and took a few sips.

After replenishing water, Wang Chunliang chose to cross the river directly.

Indeed, with such a low water level, at most it will soak up to his trouser legs, and he can pass directly.

But, let's not forget, his cold hasn't healed yet!

After crossing the 15-meter-wide river, Wang Chunliang's two shoes and trouser legs were all wet.

Chen Xu frowned slightly, sighed and said: "I have to say, Wang Chunliangkong has so much knowledge of outdoor survival, but his physical fitness and luck are too poor, now, his two shoes are all wet, which will make the soles of his feet continue to lose temperature, which is very fatal for a person with a cold." ”

However, a large amount of sediment and rocks carried by the middle and upper reaches were deposited downstream, so he could not cross the river barefoot, which was easy to break. ”

"Moreover, his heart rate is now more than 140 per minute, and his heart continues to be in the process of high-load operation, if he forcibly crosses the river barefoot, it is easy to faint when he is strongly stimulated, but he is like this now, it is estimated that it will be difficult to survive tonight!"
