Live Wilderness Challenge

"Team Chen!"

"Captain Chen, be careful!"

In an instant, Liu Yan and Sun Yue poked their heads from the cabin door, shouting anxiously.

And Yan Bin was also nervous, holding the joystick firmly, trying to stabilize the fuselage.

The audience in the live broadcast room were also terrified when they saw this scene:

"Fuck! Master Xu won't fall into a box, will he?"

"Can you not have poisoned milk?"

"Hovering at high altitude is too dangerous!"

"Helicopter: Now I have reached the limit!"

As for Chen Xu, who was on the straight-20, at the critical moment when the fuselage lost control, he hurriedly grabbed the soft rope, but because the falling speed was too fast, at this moment, his whole body was suspended above the 7500-meter-high glacier!

You know, for every 100 meters above sea level, the temperature will drop by 0.6 degrees.

At this time, in mid-November, the northern hemisphere began to enter winter, and the temperature in the upper half of Mount Everest would even drop below minus 11 degrees!

Therefore, Chen Xu is now fully armed, including cold safety clothing, thermal hats, masks, gloves, and even sunglasses.

And such all-round protection, although it can bring warmth and prevent frostbite, it also greatly hinders his body senses.

Sight, hearing, smell, and most importantly, touch!

Chen Xu was wearing gloves and wearing such a thick safety suit, he couldn't use body friction to climb up the soft rope, and he couldn't even feel that his hands were not firmly grasped!

The body is disordered, and he is swaying with the wind. If this goes on, if he slips by mistake, he will fall directly.

If you fall in the wrong place, on a steep glacier mountain, you may die!

"Yan Bin! Fly into the snow! If this continues, Team Chen will die!"

Liu Yan in the back row saw with his own eyes that Chen Xu's hands holding onto the soft rope slipped a few centimeters, and immediately shouted anxiously.

"It's not that I don't fly in, but the mountain wind inside the mountain is stronger. Now the fuselage is unstable. If I force it to fly in, the plane may be destroyed!"

Yan Bin was also very anxious, but at this time, he couldn't act recklessly.

"Hurry up and think of a way, I'm afraid Team Chen won't last long!"

When Sun Yue finished saying this, Chen Xu's hands slid down a few centimeters again, almost reaching the edge of the soft rope.

Once released, he will fall directly to the glacier below.

"It's too difficult. The fuselage is already affected by the bad turbulence, and Team Chen hangs underneath it. It's like a weight, and it's easier to break the balance!"

Yan Bin is actually doing his best.

After all, this is not a hover disorder on any land, but it happened at a height of 7500 meters, the highest peak in the world!

Generally, if a pilot can fly to such a high altitude without making mistakes, he is already considered very good.

Helicopter down.

Chen Xu seemed to have sensed Yan Bin's difficulty. He gritted his teeth, tried his best with both forearms, and the wrist flexor muscles on both sides of the radius and ulna collapsed, making his hands pinch the soft muscles like calipers. rope.

At the same time, his two pairs of eyes, also behind the goggles, kept scanning the terrain below him.

swing over, swing out...

Thanks to Galileo's laws of physics, after watching for a few seconds, he almost knew the swinging law and direction of his body!

"Yan Bin, hold on to the fuselage!"

Chen Xu let out a loud roar from below, and the next moment, under everyone's surprised gazes, while swinging backwards, he shrank his legs suddenly, and kicked out immediately while swinging to the maximum position!

Then, with this inertia, he was like a weight, and he quickly swung it forward.

"What is Master Xu doing? The more you shake like this, the easier it will be to fall?"

"Master Xu: I want to fly higher!"

"The most awesome swing in history!"

"Li Shizhen's skin!"

And the moment Chen Xu shook it vigorously, the fuselage immediately became more serious.

Fortunately, he yelled to remind him at the first time, Yan Bin quickly changed the joystick and temporarily stabilized the fuselage.

But at this time, Chen Xu has already swayed back and forth more and more, faster and faster, almost exceeding 180 degrees!

next moment!

When he echoed backwards, when he was about to end.

Suddenly, Chen Xu let go of his hands.

Under the shocking eyes of more than ten million pairs, he followed the inertia of swinging back, hugging his knees with his hands, shrinking into a ball, rolling in the air like a stuntman!

The mountain wind howled, and in his sight, the blue sky and the snow-white glaciers kept turning upside down.

Until this moment, the audience didn't understand!

It turned out that Xu Ye expanded the shaking angle to increase the inertia, and then used the inertia to fly towards the gentle slope inside the mountain!

The distance from the soft rope release point to the gentle slope was about ten meters away, and the vertical distance from him to the ground at that time was only about five or six meters.

The ratio is close to twice, according to the parabolic conclusion, this is an extremely risky decision!

But escape and escape master skills made him instinctively hug his knees and shrink the ball.

You must know that under the same quality and the same environmental conditions, the spherical shape will be projected farther than the long strip!

as predicted!

Chen Xu flew dangerously over the steep slope, and the moment he was about to fall into the snow slope, he immediately let go of his hands hugging his knees, and quickly crossed behind his head to protect his neck and head!

boom!

A muffled sound.

The moment he fell into the snowdrift, he quickly rolled his body and successfully transferred the impact force.

"Um... huh..."

After rolling for four or five meters, after stopping, Chen Xu slowly got up from the snow slope while breathing heavily.

"666, Master Xu is awesome for daring to perform stunts on Mount Everest!"

"Huaxia Gymnastics depends on you!"

"Just now, Zhen Nima scared me to death!"

Inside the helicopter, Liu Yan and Sun Yue were finally relieved to see Chen Xu landed safely.

And because of the interference of one less person's weight, Yan Bin hastily pulled the joystick, and finally straightened the fuselage back.

"Hold on! Take your time! I'm fine!"

On the snowy slope, Chen Xu yelled and waved his hands high, signaling that he was very safe.

After receiving the encouragement, Yan Bin took a deep breath, stabilized his mentality, and finally successfully flew the Z-20 to the top of the gentle slope.

Afterwards, Liu Yan and Sun Yue also slid down from the cabin with first aid equipment.

After seeing the three of them landed safely, Yan Bin drove the helicopter away, looking for a nearby place where they could stop safely.

"Okay, we have to hurry up, the weather may get worse at any time, and the oxygen content here is only less than 30.00% of the normal atmosphere, once our portable oxygen cylinders are used up, we will immediately fall into a state of hypoxia, and then Turned into altitude sickness!"

After the helicopter flew away, Chen Xu hurriedly called the two of them to his side to remind him of the seriousness of the matter.

Chapter 745 I Have Never Done Such an Experiment

It was not the first time Liu Yan and Sun Yue had rescued an emergency, so they naturally knew the severe lack of oxygen in the mountains.

That feeling is like holding a balloon, blowing air into it, and then breathing it in with your mouth, and then blowing it in again, and so on. After dozens of seconds, because the oxygen content is getting lower and lower, you will feel dizzy and very uncomfortable. !

"Okay, now we have limited manpower. If we want to find the affected people in a short time, we can only be divided into three groups. With this point as the center, the three of us form a fan shape, divide into three directions, radiate outward, and search carpet."

"Once there is any situation, use the satellite walkie-talkie to call immediately. After the other two hear the signal, they must first write down the current search coordinates, and then rush to the call point immediately. Remember, it is immediately!"

Time is tight, Chen Xu can only use the simplest method.

"remember!"

Liu Yan and Sun Yue answered almost in unison.

Next, the three of them took out their snowshoes from their backpacks and buckled them on the soles of their shoes. Then, with their backs facing each other, they held portable life detectors and carefully searched in the direction they decided.

The life detectors they used were somewhat similar to the metal detectors used by Chen Xu during the live broadcast on Dakai Mada Island, but this is a very advanced radar detector, which can emit electromagnetic waves through the body to penetrate the snow layer. Radiates deep.

When it senses the breathing, body movement and other vital signs of the buried life, it will immediately feed back on the screen, and can roughly measure the distance and depth of the buried life, and it will not be affected by the ambient temperature, hot objects and sound interference. Influence.

It's a pity that the sound waves emitted by the portable radar life detection gas have a limited bandwidth and cannot carry out a large-scale search, so they can only walk out one by one with three people.

"Everyone must remember that if one day, you also take a helicopter and quickly enter such a high-altitude area from a low altitude, the first thing to do is to try to slow down everything."

"You must know that in a hypoxic state, if the body wants to maintain normal life activities, the heart must work harder to transport oxygen to various parts. This is called climate adaptation."

"Scientists have done pre-experimental tests. If a person has not experienced plateau adaptation and is suddenly thrown to the top of Mount Everest, it will take only 5 minutes for him to die immediately."

As soon as Chen Xu finished these few words, the audience couldn't help but joked:

"666, didn't he freeze to death?"

"Scientists have also done it, blindfolded a person, cut his wrist with a fake knife, and put the sound of bleeding next to him. After 100 years, he will be frightened to death!"

"Scientist: I haven't done these experiments."

"2333333, you are real skins!"

Looking at these "teardown" barrages, Chen Xu couldn't help but continue to explain:

"So, survival and self-rescue in high-altitude snow-capped mountains is very similar to mountaineering. The most important thing is to control your breathing and physical strength, that is, keep your breathing evenly at all times, so as to save the consumption of oxygen cylinders."

"And one of the most effective ways to save energy is snowshoes. The size of snowshoes is like a small snowshoe. It can effectively distribute the weight of the human body over a larger area and prevent the feet from completely sinking into the snow."

"In this way, you will save the action of stepping into the snowdrift and pulling it out again. You can't see it once or twice, but if you walk for an hour, you will save more than half of your energy. And saving energy means saving oxygen! "

"Of course, if you don't have snowshoes in the wild, you can also use ropes and cloth strips to tie the branches into a plane, and finally fix them on the shoes."

During the search and rescue process, Chen Xu kept telling the audience some important skills related to self-rescue and survival in the snow-capped mountains while staring at the equipment.

"Another important point is the eyes. At an altitude of 7500 meters, it is already considered as the closest position on the earth to the sun. The sunlight at this height is directly shining down, and the ultraviolet radiation is extremely strong, so you must not stare at it for a long time. sun."

"Besides, because the snow surface is exposed to the sun, the snowflakes on the surface will melt into small ice crystals, reflecting the light. If you stare at the snow surface for a long time, you will easily suffer from snow blindness. The best way is to wear goggles."

"If you don't have one, you can use cloth strips instead. At the position of the eyes, use a sharp tool to cut a gap. Because the gap is small, the things that the eyes can see and the light source they receive are small, thus avoiding snow blindness. occur."

Just when Chen Xu had just finished speaking these few words.

Suddenly, there was a "beep" from the satellite intercom on the chest:

"Report to Team Chen! The situation of the friends in the southeast direction!"

It's Liu Yan's position!

"Stand by, we'll be there right away!"

After Chen Xu finished answering, he immediately inserted the trekking pole in his backpack in front of him as a mark.

Then, he quickly turned his head and rushed towards Liu Yan.

One minute later, the three of them gathered at the spot where Liu Yan discovered the anomaly.

I saw that on the screen of the radar life detector, there was a red dot about two meters deep under the snow!

"The heartbeat is weak, but there are indeed signs of life! Hurry up, get ready to dig!"

After Chen Xu confirmed the signal, he quickly took out a portable snow shovel from his backpack, which looked like a foldable military shovel.

Therefore, Liu Yan and Sun Yue followed suit.

The depth of two meters is not much. It took the three of them about 2 minutes to dig to the position of 1.5 meters six.

"Stop! Use your hands instead, don't hurt the victim!"

Seeing that he was about to reach the signal position, Chen Xu immediately ordered to stop.
