It's cold!

Seeing Bi Fang take off his heavy coat, the first reaction of all the audience was to shudder, especially when they saw Bi Fang take off almost a pair of underwear, they all grew their mouths.

[Crazy? 】

[Is Lao Fang's brain frozen? 】

[Is this the legendary synaesthesia?] Even though I just looked at it, I felt cold to the touch......]

[What a synaesthesia! I feel it too! 】

Even Rob was shocked, he still remembered the first time he led the team to 7,600 meters, and when he decided to sprint that night, the next morning, two people in the team suffered intracerebral hemorrhages, and they lost their judgment as if they were drunk.

The origin of the discovery of this problem is that Rob found that the shoes of the two were worn backwards, not only did they not distinguish between the left and right, but they even made them not remember the names of their teammates when they recognized them.

Bi Fang's brain is frozen?

Of course not.

He's a race against time.

Why is the last fourth camp on Everest at 8,000 meters?

Because 8,000 meters is a line of life and death.

Beyond this altitude, the human body is always in a state of near death, and mountaineering is to return to safety before you actually die.

Most mountaineering teams are accustomed to planning 2 p.m. as the 8,000-metre "cut-off time" – to allow enough time and energy to descend to ensure safety, they must retreat wherever they reach at 2 p.m.

Once the sun goes down, because the air itself is very dry at this altitude, and the clouds that can store heat radiation are all underfoot, the temperature will be extremely rapid, and the human body surface temperature will be about 35 degrees Celsius, which is about 80 degrees higher than the ambient temperature, which is the temperature difference between boiling water and room temperature.

Even if you put it in a thermos, the temperature of boiling water will quickly drop to about 90 degrees, not to mention the human body at this time.

Coupled with the howling wind, it is very easy to fall off the cliff.

Pulmonary edema, cerebral edema, hypothermia (freezing to death), and slipping and falling are the four major killers on the line of life and death.

In this thin air area, sometimes a cough can kill a person, and even taking a breath can cause the pain of tearing the liver and splitting the abdomen.

Of course, thick clothes are warmer, but Bi Fang now wants more flexibility to make his climb faster!

Reach the summit in fourteen hours, and back!

So Bi Fang changed out of his thick equipment and boots that barely bent his ankles, and instead took out a black 'wetsuit' from his backpack.

[This is the ...... Wetsuit? 】

The audience was dumbfounded, is the wetsuit so fierce?

At this time, Yao Junle, who was watching the live broadcast, recognized it, this is one of his treasures, cold-resistant clothing made of aviation-grade materials, completely close-fitting, and can easily resist low temperatures of minus 20 degrees.

Because it was a one-piece design, Bi Fang was more difficult to wear, and fortunately he finally put it on before he got frostbitten, but it was obviously not enough to resist minus 20 degrees, so he pulled out a tight-fitting assault suit.

At this time, Bi Fang's body was already "pitch black", only the orange lines on the jacket flashed fluorescent, from the shoulder blades on the back to the waist.

Changing into hiking boots, Bi Fang took out a head mask from his backpack, unzipped it, and stayed on his head.

The mask shimmers metallicly in the dark, but it is actually made of synthetic plastic, except for a small piece of soft cloth at the back of the head and a white plastic bottle at the eyes.

"The temperature of minus fifteen degrees, coupled with the wind chill effect, only a few minutes, our skin will be severely frostbitten, in order to facilitate the observation of the environment, I did not prepare a jacket with a hat, that is not enough, so I brought a mask."

It is difficult to imagine the power of extremely cold weather without ordinary people, if it is an army, you can't even put weapons in the tent, because once you put it in the warm tent for a long time, once you go to the cold outdoors, the sudden drop in temperature can directly freeze the crosshair of the optical sight.

Sweat and ice, freezing and cracking of the barrel are common.

In the northeast that year, the 1st Marine Division of the Ugly Army lost more than 7,000 men in the severe cold alone, plus many amputations.

But on Mount Everest, minus 40 degrees is normal!

When everything was ready, looking at the mountaineering suit like a combat uniform, many spectators' eyes lit up.

Tainyima is handsome!

Completely renewed, the initial bloat is gone, replaced by a sharp, light and agile one.

The whole body is pitch black, and the orange fluorescent lines on the back make Bi Fang's whole person have a decisive momentum.

[Coach, teach me how to dress! ] 】

[The soul of the second middle school is burning! 】

[Is this going to climb the mountain? No, it's to save the world! 】

[Rush fucking! ] 】

【Enlightenment! 】

[It's a bit like a dark version of the death knell!] 】

Bringing a headlamp and inserting a 500ml hydration bag in his clothes pocket, Bi Fang brought a smaller backpack, like a bag hidden behind his back, which only contained energy bars and some special items, plus a spare pair of gloves and a live broadcaster, and his mobile phone was inserted in the inner pocket of his chest.

"Energy glue can't be brought, only energy bars, although the glue is better to digest, but you have to face the problem that it will freeze, the same is true for water, be sure to put a bag close to you, in addition, if you want to climb to the top to take pictures, or call your family, then don't put your phone in your bag, but also put it in your chest to measure, the temperature of this position can prevent the battery from striking quickly in the extreme cold."

When everything was ready, the original heavy clothes and backpack were found by Bi Fang to find a place to hide, and he would take these clothes when he returned.

Right now

Sprint!

Bi Fang turned around and trotted up!

Countless people breathless.

This guy is still running!

Luo Bu's pupils had shrunk to the size of a needle's eye, and he subconsciously leaned back, he thought that he had judged Bi Fang's physical fitness, but he didn't expect it to be underestimated!

This guy, this guy doesn't want to be a human, it's just a machine!

Imagine if your heart beats more than 200 beats per minute just by standing, and it takes half a minute to take a step, you can experience the existence of the unity of body and mind - and the brain will also become very dull due to extreme conditions.

The author of "Into the Thin Air" saw a corpse on the mountain and stared at it for two minutes before realizing what he was seeing.

In such a situation, it is difficult to expect people to make rational judgments, and it will be extremely difficult to walk.

But right now, right now, there is a person jogging up the mountain at 7,600 meters!

Ice and snow stick to the towering black rocks and seem to fall at any moment. The "yellow belt" in the mixed area of ice or snow rock is very tricky, and Bi Fang's skillful climbing skills have almost become a conditioned reflex.

Five hours later, eight thousand meters above sea level.

The point where the last camp is located.

Why is the final fourth camp no more, no less than 8,000 meters?

Coincidental?

Of course not.

Because it's a tipping line that everyone recognizes.

It is also called - the death line.

At an altitude of 8,000 meters, low air pressure can already have a serious impact on the human body, making the already difficult climb impossible.

The consequences of a minor storm can be fatal; Only perfect weather and snowfall can bring the least chance of climbing success. But at the final stage of climbing, no one can choose such an opportunity......

To put it simply, it's one of the healthiest ways to use drugs, and it's an 8000-meter death game.

In everyday life, mistakes can be corrected, compromises can make up for mistakes, but at this particular time, your actions will be life and death.

Are you scared?

Bi Fang looked up at the sky, the morning sun rose from the edge of the clouds, and the halo slowly dispersed, just like his hot heart.

Bi Fang wanted to laugh, but he couldn't, because his breathing had begun to struggle, and any breath would disrupt the rhythm.

Looking at the visible top of the mountain, that's where you're going.

He was never afraid.

We can't reasonably infer the world above our heads – the ancients didn't understand that they invented God; Modern people don't understand, so there is mountaineering.
