Live Wilderness Adventure

Chapter 391 Sneezing: It's Really Not Me

"OK, come here quickly, there's no problem."

Smoothly sliding to the opposite side, Bi Fang waved to his companion behind him.

"MY GOD." Jarrett came to the edge of the crack, and as soon as he looked up, his legs softened, and his hands began to make the sign of the cross in front of his chest.

"Come on, don't be afraid, look, the rope is nailed very firmly, and there is a safety rope, even if you let go of your hand, you won't fall, as long as you move properly." Bi Fang grabbed the long rope and kept shaking it, falling to the ground The spikes were motionless.

Every mountain climbing season, the Sherpas will repair the road on the glacier, set up ladders, drill holes in the glacier, drive in nails as long as the forearm, and tie long ropes to make it easier for climbers to pass. Their source of income is also their work, and people die almost every year because of it.

Here, Sherpas have become almost a consumable.

Trembling, Jarrett wrapped the safety rope around his body and tied it. Looking at the bottomless abyss, he felt that his brain was even more deprived of oxygen. He grabbed the ascender, and Yao Jun behind him saw it and pushed it.

"ah!!!"

"Okay, okay, you've arrived, don't shout, it will be really troublesome in case of an avalanche."

"Ah, uh, huh?" Jarrett opened his eyes blankly, and stepped on the solid ice, as if it was unreal.

Looking at the glacier behind him, Jarrett suddenly felt complacent. The Khumbu Glacier is just like that. Once you close your eyes and open it, won’t it pass?

When all the people behind came over one after another, Rob breathed a sigh of relief, clapped his hands and said: "Okay, this is the first glacier we have crossed, it's very simple, but there are hundreds of others waiting behind. Us! Don't let your guard down!"

Into, hundreds of thousands?

"."

"Is there really no other way?" Jarrett ran over and grabbed Bi Fang's arm.

"Really not, look at it." Bi Fang stretched out his hand and pointed to the towering glacier not far away, as well as the faintly visible Nuptse Peak and the huge Mount Everest on both sides of the glacier. When he thought of climbing these peaks, he would It makes people feel a lot of pressure.

"These hanging glaciers, Nuptse Peak and Mount Everest are too close to us, and the snow on them is very thick, and the slightest vibration may collapse, so it is best not to scream next time, and try to bear it as much as you can. Dangerous, it will avalanche."

Jarrett: "o(╥﹏╥)o"

【Jarrett: I'm so stupid to listen to you】

[The false Kumbu Glacier, a big crack that cannot be seen to the bottom, the real Kumbu Glacier, there are hundreds of them like this! 】

[I fucking thought that the Khumbu Glacier was just this crack, and I was curious why so many people died here. . Shouldn't the pits be filled with so many deaths? . . 】

【Glacier: I have been filled】

【Hey】

[No, if the glacier moves every day, don’t the Sherpas have to come up to repair it every day? 】

"In theory, it is, but it is very difficult to operate in practice, so many times climbers will encounter situations where there is no road. At this time, we have to build ladders ourselves. Have you seen my backpack?"

Bi Fang put down the backpack for everyone to see, and everyone suddenly found that there was a long telescopic ladder stuffed between the shoulder strap and the bag, but the whole bag looked stiff and straight!

"This is a telescopic ladder. It is only one meter long when it is closed, but it is actually four meters long when it is unfolded. Once we encounter a place where there is no road, we need to put the ladder on it and go there. Because it is not fixed, this That's where the real danger lies."

"Mount Everest has very high requirements for equipment. In many places, even aerospace-grade materials are used, just like this ordinary climbing ladder. First of all, it is necessary to ensure that the materials can work at extremely low temperatures.

Many steel materials will become brittle at low temperatures. For example, Q345E can only withstand the impact of minus 40 degrees. If it is lower, it will become brittle and cannot be used. The lowest temperature on Mount Everest can be close to minus 50 degrees! Therefore, aluminum with better low temperature resistance should be selected. "

Bi Fang took a breath and continued, "Secondly, we must reduce the weight while ensuring the structural strength as much as possible, so titanium is not an option. The weight of titanium is twice that of aluminum. The specific strength of aluminum is already high enough.

The third is the structural design. The more complex the design, the easier it is to break. Even a telescopic design may become a fatal factor in the environment of Mount Everest. Therefore, the design of the connection must be as simple as possible. "

In addition to tickets, equipment is also one of the bulk.

Just a bottle of oxygen, plus the high mountain freight, the price can be as high as 500 U.S. dollars.

Many people can't even take a breath of oxygen on Mount Everest with a month's salary.

There are also down jackets, the outer layer is windproof and waterproof, and it needs to remain soft in severe cold, and it should be as light as possible.

The zipper needs to be designed with fully-pressed waterproof tape to ensure smooth opening and closing when wearing thick gloves; the inside is filled with eider down or goose down, and the down filling must be at least 90% in order to withstand minus 30+ ℃ in strong winds low temperature.

"There are also mountaineering boots specially designed for altitudes above 8,000 meters. The pair I wear weighs 1413 grams... Running shoes are generally 300g, and ordinary outdoor hiking shoes are mostly 500 to 800g; snow mountain climbing is very afraid of frostbite, and many Climbers will be forced to amputate their limbs after going down the mountain, because their limbs have been frozen to death. The warmth of shoes is very important. My pair is not so much a pair of shoes as a set of shoes and boots. Outer boots, inner boots and legs The cover plus the insole and the outermost outsole; this makes it completely unable to bend like ordinary shoes, and the feet and calves feel firmly trapped."

Bi Fang lifted up his trouser legs and showed off his thick boots to everyone.

It is simply a huge thickened version of snow boots, connected together as a whole, the flexibility looks very poor.

No way, necessary sacrifices must be made for warmth retention.

In the previous life, De Ye had to amputate his toes because of inadequate measures to survive and keep warm in an extremely cold area, resulting in necrosis of his toes. Bi Fang's eyelids were twitching wildly when he saw it, and his toes were extremely swollen from the cold.

"Frostbite, it's cold at the beginning, and when the tissue gradually freezes to death, you will feel pain and stinging pain, because your tissue fluid is freezing, and the blood turns into ice crystals, pierces the cell membrane, and explodes the entire cell .

This is an irreversible process. Even if it recovers, the cells cannot recover, but they can still be recovered, because your cells will still reproduce, but when the degree of necrosis is so high that even the nerves are damaged, It must be amputated.

Your toe is completely irreversible at this time, it is just a piece of frozen meat attached to your body, and when you return to a warm place, it will become a piece of carrion, if you don’t cut it off, your entire right leg and even your life will be threatened. "

Yao Jun listened carefully, but as he listened, his toes felt cold. He lowered his head to look, but luckily his toes were still there.

Bastard, that's an amputation, can you stop saying it so lightly!

"However, there is no road longer than feet, and no mountain higher than people, unless it is at high altitudes and north and south poles. Under normal conditions, wearing these can really suffocate people directly."

Bi Fang smiled and stepped over a small crack. The crack was only half a meter wide. It seemed that it had just appeared and was still very young. Maybe after ten years, it would grow into a large glacier.

【How much does the equipment cost, it makes me give up】

[I found the same model on Amazon. . . Six thousand knives. . . 】

[A little less than 40,000, um, much cheaper than I thought]

[The boss has appeared! 】

[The courier is delivered under the big ben, and the delivery is placed on the bottom. 】

[Learned again, discovered one of Fang Shen's hidden professions, material mechanics! Take a notebook and write it down, astrologer, zoologist. Add a materials scientist. 】

[So what else is there that Fang doesn't know, say it all at once, let me scratch my ass with a knife, open my eyes]

Bi Fang smiled: "Yes, I actually don't know many things, such as why the ice is so slippery."

Why is the ice so slippery?

Fang Shen doesn't know?

Question marks popped up on the audience's face, are you kidding me?

Tony thinks this is an extremely simple question, because it is ice, so it is slippery, but it is not that simple when these words come from Fang Shen. Tony raised his head and looked at his little friend Peter who had not seen for a long time. .

"Peter, why is the ice so slippery?"

Peter bit his pen and didn't hear what Tony said at all. Since he was encouraged by Fang Shen last time, his mind was so distracted, he had been doing outdoor research, and he didn't even watch Fang Shen's live broadcast.

I even set up a website for migratory birds. Although there is not much traffic at the moment, it is indeed a good start. I also got in touch with the migratory bird protection organization and updated it all the time.

This year will soon be the time for the group of migratory birds to come back, and a large number of them are already migrating.

Hey, I don't know if it will be smoother this time, those damn poachers should have died long ago.

"Peter? Peter!"

"Uh, huh?" Tony yelled several times, and Peter woke up suddenly, only to find that his partner was talking to him.

"What's wrong?"

Tony put his hand on his forehead: "What's wrong with you recently, I remember you don't like to watch God Fang's live broadcast the most? The last two times you haven't been online to chase stars, something is wrong, very something is wrong, you are not in love, are you? Is it Mary from Class 3, or Gwen next door? It can’t be Mary, but she’s too young, you might not be able to play with her.”

Peter twitched the corner of his mouth, what was the point of this, he and Mary communicated in a friendly manner, and we were all lovers of geese and birds, so there was no meaning in that regard, okay?

By the way, there is also a photo album to give her. Tony didn’t mention it, he forgot, and I will deliver it to Mary when Tony leaves at night. She seems to have a cold, so it should be inconvenient to go out. She should drink more hot water .

"Hello? Why are you in a daze again?" Tony stretched out his hand and shook it in front of Peter's eyes.

"Um, okay, what's the matter?"

"Why is the ice so slippery?" Peter bit his finger and hesitated for a while, "Because it's ice?"

"fool!"

[Because this thing is a fucking unsolved mystery in the world! 】

[? True or false,,, is this thing an unsolved mystery? 】

[Isn't it because of the smooth surface? 】

Bi Fang laughed, but the next moment he was choked and coughed twice.

Damn, I'm starting to feel hypoxic too.

"If you are interested in this question, you can search the Internet by yourself, but this thing is indeed an unsolved mystery. Ice is slippery because there is a layer of water film on it, which acts as a lubricating oil, and no matter how low the temperature is, the water film will It exists, but the molecular structure is not ordinary water, as for why, the scientific community really does not know until now.”

"Walking in broken glaciers, when encountering a cracked ice crack that needs to be crossed, try to step on the front end of the mountain boots to the edge of the crack, see the edge of the other crack clearly, and stride across without hesitation.

It is best to string everyone up with a rope, so that if someone accidentally falls into the ice crevasse, he can be pulled up without any danger, but this requires that the people in the team have a high degree of execution High, otherwise there may be a situation where there are too many, and then no matter how you pull it, you will not be able to pull it up. "

After walking for more than half an hour, the crowd continued to step over large and small cracks.

The audience in the live broadcast room were all terrified, especially as the further back, all kinds of glaciers appeared.

Not all glaciers can be crossed easily with a rope. Bi Fang is climbing, not descending. This kind of glaciers is only a small part. Most of them are high in the front and low in the back. Going up the rope is like climbing the steps of giants.

There are cracks at the bottom, which will be more dangerous. Two sections of the ladder are tied together, and the two ends are draped, and people climb up from below. You can only hope that your teammates are reliable enough to support you.

In this case, Bi Fang is the first to go up, which is the most dangerous, because you don't know whether the ropes bound to the ladder are loose, and when Bi Fang goes up, you can carry out secondary inspection and reinforcement.

"My life is in your hands, help me up."

"Don't worry." Yao Jun said OK, "I won't support the wall when I'm in the wind, I'll support you!"

Bi Fang laughed and cursed, and put the backpack on the ground.

"When climbing a ladder, it's best to go up with a light load. The center of gravity is more stable. After you climb up, you can use a rope to pull the bag up. Although this is a bit troublesome, it is better than safety."

I thought the weight was too light, and the ladder was made of two bundled ladders. Under the cold wind, the whole ladder seemed a bit precarious and kept shaking.

When Bi Fang stepped on it and came directly above the abyss, the drone also came to the sky above his head.

At an altitude of nearly 6,000 meters, coupled with the cold wind, even the drone was already shaky, and the shaking of the camera aggravated the tension and terror of the entire operation.

On the swaying long ladder, Bi Fang walked alone above the abyss, above the earth, below the sky, heading towards the snow-capped mountains.

Suddenly, Yao Jun sneezed suddenly, and the long ladder shook suddenly.

Bi Fang immediately hugged the long ladder tightly, and Yao Jun also knew that he had made a mistake, so he hurriedly supported the ladder, but before the ladder was stable, Yao Jun opened his mouth wide and let out a whooping sound unconsciously.

There were some strange sounds in the howling cold wind.

Bi Fang hugged the long ladder tightly and glanced around. He felt the danger, his spine was chilling, and the long ladder under him began to tremble, not because of the wind, but because of it!

The tremors gradually intensified, and the newly fallen snow slid on the ice surface. Everyone also noticed this abnormality and looked around nervously.

"Avalanche! Rob! It's Avalanche!"

Bi Fang pointed at the top of the snow peak and roared.
