Seeing Bifang take off his heavy coat, the first reaction of all the viewers was to shudder. Especially when they saw Bifang stripping down to almost only a pair of underwear, they all opened their mouths.
【crazy?】
[Is Lao Fang’s brain frozen? 】
[Is this the legendary synaesthesia? Although I just looked at it, I felt cold to the touch. 】
【What a synaesthesia! I feel it too!】
Even Rob was shocked. He still remembers the first time he led the team to the 7,600 meters. When he decided to sprint that night, two people in the team had intracerebral hemorrhage early the next morning, as if they were drunk.
The ability to judge.
It was found that the origin of this problem was that Rob found that the two people's shoes were worn backwards. Not only were they unable to distinguish between left and right, they even couldn't remember the names of their teammates when they recognized them.
Bifang's brain is frozen?
of course not.
He is racing against time.
Why is the final fourth camp on Mount Everest located at no more than no less than 8,000 meters?
Because eight thousand meters is a life and death line.
Above this altitude, the human body is always on the verge of death, and climbing means returning to a safe zone before you actually die.
Most mountaineering teams are accustomed to planning 2 p.m. as the "cut-off time" at 8,000 meters - leaving enough time and physical strength for the descent to ensure safety. No matter where they climb at 2 p.m., they must descend.
Once the sun goes down, since the air itself is very dry at this height and the clouds that can preserve thermal radiation are all under the feet, the temperature will drop extremely rapidly. The human body surface temperature is about 35 degrees Celsius, which is about 80 degrees higher than the ambient temperature. This is
The temperature difference between boiling water and room temperature.
Even if you put boiling water in a thermos, the temperature will quickly drop to about 90 degrees, not to mention the human body at this time.
Coupled with the howling wind, it is easy to fall off the cliff.
Pulmonary edema, cerebral edema, hypothermia (freezing to death), and slipping are the four major killers on the line between life and death.
In this thin air area, sometimes a cough can kill a person, and even taking a breath can cause pain that tears the liver and abdomen.
Thick clothes are of course more warm, but what Bi Fang wants now is higher flexibility so that he can climb faster!
Climb to the top and back in fourteen hours!
So Bi Fang changed out of his thick equipment and long boots that could barely bend his ankles, and instead took out a black 'wetsuit' from his backpack.
【This is a diving suit?】
The audience was dumbfounded. Is the diving suit so powerful?
At this time, Yao Jun was happy watching the live broadcast. He recognized that this was one of his treasures. The cold-resistant clothing made of aviation-grade materials was completely close to the body and could easily withstand temperatures as low as minus 20 degrees Celsius.
Because it was a one-piece design, it was difficult for Bi Fang to put it on. Fortunately, he finally put it on before getting frostbite. However, it was obviously not enough to withstand minus twenty degrees, so he pulled out a tight-fitting assault suit.
At this time, Bifang's body was already "pitch black", with only the orange lines on the jacket shining fluorescently, which were gathered from the shoulder blades on the back to the waist.
After putting on hiking boots, Bi Fang took out a hooded mask from his backpack, unzipped it, and put it on his head.
The mask shimmered with metallic luster in the dark, but was actually made of synthetic plastic. Only the neck area under the back of the head was a small piece of soft cloth, and the eyes were white plastic pieces. The outside could be seen clearly from the inside, but not from the outside.
Go inside.
Its function is to keep warm, and at the same time help with cold and heat exchange, preventing large swaths of water vapor caused by breathing from soaking into the mask and turning into an ice mask.
"With a temperature of minus 15 degrees, coupled with the wind chill effect, our skin will suffer severe frostbite in just a few minutes. In order to facilitate observation of the environment, I did not prepare a jacket with a hood, which is not enough, so I wore a mask."
It is difficult for ordinary people to imagine the power of extreme cold weather. If you are in the army, you cannot even put weapons in a tent, because once you leave it in a warm tent for a long time, the temperature will drop sharply when you go outdoors in the freezing cold.
It can directly freeze the front sight of the optical sight.
It is normal for the gun to freeze due to sweating and the barrel of the gun to crack.
In the Northeast, the First Marine Division of the Ugly Army lost more than 7,000 men due to the severe cold alone, and many had their limbs amputated.
But on Mount Everest, minus 40 degrees is normal!
When everything was ready, many viewers' eyes lit up when they looked at the mountaineering suit that looked like a combat uniform.
So damn handsome!
Completely renewed, the initial bloatiness disappeared, replaced by something sharp, light and agile.
The whole body is dark, and the orange fluorescent lines on the back give Bifang a decisive aura.
【Coach, teach me how to dress!】
[The soul of the second grade is burning!]
【Are you going to climb a mountain? No, you are saving the world!】
【Go to hell!】
【enlighten!】
[A bit like a dark version of Deathstroke!]
Wearing a headlamp and inserting a 500ml water bag into his pocket, Bi Fang brought a smaller backpack, which was like a bag hidden behind his back. It only contained energy bars and some special items, plus a spare pair.
The gloves, live streamer, and mobile phone were inserted into the inner pocket of the chest.
"You cannot bring energy gel, only energy bars. Although gel is easier to digest, you have to face the problem that it will freeze. The same goes for water. You must keep a bag close to your body. In addition, if you want to take pictures at the top,
Or to make a call to your family, don’t put your phone in your bag, but put it inside your chest for testing. The temperature at this location can prevent the battery from quickly shutting down in extreme cold.”
When everything was ready, Bi Fang found a place to hide the original heavy clothes and backpack. He would get these clothes when he came back.
Now,
Sprint!
Bi Fang turned around and started running!
Countless people's breath was stagnant.
This guy is still running!
Rob's pupils had shrunk to the size of a pinhole, and he subconsciously leaned back. He thought he had judged Bifang's physical fitness, but he still underestimated it!
This guy, this guy doesn't even want to be a human being, he is simply a machine!
Imagine, if your heartbeat exceeds 200 beats per minute just standing, and it takes half a minute to take a step, you can experience the existence of body and mind as one - the brain will also become very slow due to extreme conditions at this time.
The author of "Into the Thin Air" saw a corpse on the mountain and stared blankly for two minutes before he understood what he saw.
It is difficult to expect people to make rational judgments under such circumstances, and even walking will be extremely difficult.
But right now, there is a person jogging and climbing at 7,600 meters!
The ice and snow stuck to the towering black rocks, seemingly ready to fall off at any time. The "yellow belts" in the ice-rock or snow-rock mixed areas were extremely tricky and tricky. Bifang used his climbing skills skillfully, almost becoming a conditioned reflex.
Five hours later, the altitude was 8,000 meters.
The last campsite is located.
Why is the final fourth camp 8,000 meters long, no more, no less?
coincide?
of course not.
Because this is a critical line recognized by everyone.
It is also called the line of death.
At an altitude of 8,000 meters, low air pressure can have a serious impact on the human body, making an already difficult climb impossible.
The consequences of a minor storm can be fatal; only perfect weather and snowfall can bring even the slightest chance of a successful climb. But in the final stages of mountaineering, no one can choose such an opportunity...
To put it simply, it is the healthiest way to take drugs. It is an 8,000-meter death game.
In everyday life, mistakes can be corrected and compromises can make up for mistakes, but at this particular time, your actions can mean the difference between life and death.
Will you be afraid?
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 burning heart.
Bi Fang wanted to laugh, but couldn't, because his breathing had begun to become difficult, and any breath would disrupt his rhythm.
Looking at the visible mountain top, that is where you want to go.
He is never afraid.
We cannot reason about the world above our heads - the ancients didn't understand, so they invented gods; modern people don't understand, so they invented mountain climbing.
