Live Wilderness Adventure

"Live Wild Adventure (

Take a hole brothers.

There have been a lot of meals these two days.

After writing it, modify it in the early morning, which is equivalent to anti-theft.

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

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

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

"comeon, don't be afraid, you see, the rope is nailed firmly, and there is a safety rope, even if you let go, it won't fall, as long as you move properly." Bi Fang grabbed the long rope and kept shaking, and the ground The spike did not move.

Every mountaineering season, the Sherpas repair the roads on the glacier, erect ladders, drill holes on the glacier, drive forearm-long nails, and tie long ropes to facilitate the climbers to pass through. It's their source of income, it's their job, and people die from it almost every year.

Here, Sherpas have become almost a consumable item.

Jarrett trembled and tied the safety rope around his body, looking at the bottomless abyss, only to feel that his brain was even more oxygen-deprived, grabbed the ascender, and Yao Jun, who was behind him, glanced at it and pushed it directly.

"what!!"

"Okay, okay, you've already arrived, don't call, 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 unreal.

Looking at the glacier behind him, Jarrett suddenly felt proud. Khumbu Glacier, that's all, as soon as he closed his eyes and opened his eyes, didn't he pass by?

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

Into, hundreds or thousands?

"..."

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

"It's not really, and you can see." Bi Fang stretched out his hand and pointed to the towering hanging glacier not far away, as well as the faintly visible Nuzi Peak and the huge Mount Everest on both sides of the glacier. When he thought of climbing these peaks, he would It made people feel a lot of pressure, "These hanging glaciers, Nuzi Peak and Mount Everest are too close to us, the snow on them is very thick, and it may collapse if there is a slight vibration, so it's best not to call again next time, Endure it as much as you can, it's very dangerous, and there will be an avalanche."

Jarrett: "o(╥﹏╥)o"

[Jarrett: It's silly to listen to my grandfather]

[The fake Khumbu Glacier, a huge crack that cannot be seen to the end, the real Kumbu Glacier, like this, there are hundreds of thousands! 】

[I also **** thought the Khumbu Glacier was this crack, and I was wondering why so many people died here. . Shouldn't all the holes be filled with so many deaths? . . 】

[Glacier: I have been filled up]

【Huh】

[No, if the glacier moves every day, don’t the Sherpas come up every day for maintenance? 】

"This is the case in theory, but it is very difficult to operate in practice, so many times climbers will encounter a situation where there is no road. At this time, we have to build our own ladders. See my backpack?"

Bi Fang put down the backpack for everyone to see, and everyone was surprised to find that there was a long retractable ladder in the interlayer between the strap and the bag, but the whole bag looked stiff and very straight!

"This is a telescopic ladder, it is only one meter long when folded, but it is actually four meters long when unfolded. Once we encounter the kind of place where there is no road, we need to put up the ladder and go over, because there is no fixed, this That's where the real danger is."

"Everest's equipment requirements are very, very high, and aerospace-grade materials are even used in many places. Just like this ordinary climbing ladder, the first thing is to ensure that the materials can work at extremely low temperatures. It will become brittle at the bottom. For example, Q345E can only withstand the impact of minus 40 degrees, and it will become brittle if it is lower, and it cannot be used. The lowest temperature on Mount Everest can even be close to minus fifty degrees! Aluminum is better at lower temperatures.”

Bi Fang took a sigh of relief and continued: "The second is to reduce the weight while ensuring the structural strength as much as possible, so titanium cannot be selected. The weight of titanium is almost twice that of aluminum, and the specific strength of aluminum is It is also 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 Everest environment, so the design of the joint must be as simple as possible.”

In addition to the tickets, the equipment is also one of the big ones. Just a bottle of oxygen, plus the high-mountain freight, can cost as much as 500 yuan. Many people's monthly salary can't even take a sip on Mount Everest.

There are also down jackets. The outer layer is windproof and waterproof. It needs to be soft in severe cold and as light as possible. The zipper needs to be designed with a fully-pressed tape waterproof sticker, which can also ensure smooth opening and closing when wearing thick gloves; The inside is filled with duck down or goose down, and the filling capacity is about 90%, which can cope with the low temperature of minus 30+℃ in strong wind.

"There are also hiking boots specially designed for altitudes above 8,000 meters. The weight of the pair I wear is 1413 grams... The running shoes are generally 300g, and most of the ordinary outdoor hiking shoes are only 500-800g; because climbing snow mountains is very afraid of frostbite, many Climbers will be forced to amputate their limbs after going down the mountain, because the limbs have been frozen to death, and the warmth of the shoes must be top-notch. My pair is not so much a pair of shoes as it is a combination of shoes and boots, outer boots and inner boots Add leg covers, insoles, and an outer outsole; this makes him completely unable to bend like a normal shoe, and his feet and calves are firmly trapped."

Bi Fang lifted up his trouser legs and showed his thick boots to everyone. They were simply huge thicker snow boots, and they were connected together as a whole, with poor flexibility and no way. This was for warmth. necessary sacrifice.

In the previous life, Master De had to have his toes necrotic because of inadequate measures to survive and keep warm in the extreme cold zone. Bi Fang saw his eyelids twitching wildly, and his toes were extremely swollen from freezing.

"Frostbite, it's cold at the beginning, and when the tissue gradually freezes to death, you will feel pain and tingling, because your tissue fluid is freezing, and your blood turns into ice crystals that pierce the cell membrane, ripping the entire cell. Exploding, this is already an irreversible process. Even if it recovers, it is impossible for the cells to recover. It can still be recovered at this time. Your cells will still reproduce, but when the degree of necrosis is too high, even the nerves are damaged. In this case, it must be amputated. Your toe is completely irreversible at this time. It is just a piece of frozen meat that sticks to your body. When you return to a warm place, it will become a piece of rotten flesh. If you don’t cut it off , your entire right leg and even your life would be at risk."

Yao Jun listened carefully, but when he listened, he felt his toes get cold. He looked down and fortunately his toes were still there.

Asshole, that's an amputation, can you not put it so lightly!

"However, there is no road longer than feet, and there is no mountain higher than people, except for high altitudes and the north and south poles. Wearing these under normal conditions can really kill people directly."

Bi Fang smiled, raised his foot and stepped over a small crack. This crack is only half a meter wide. It seems to have just appeared, and it is still very young. Maybe it will grow into a big glacier in ten years.

[How much does the equipment cost, let me give up]

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

[It's less than 40,000 points, um, much cheaper than I thought]

【The big guy has appeared! 】

[Express delivery under Big Ben, and the top is placed under the bottom. 】

[Learned again, and discovered one of Fangshen's hidden occupations, mechanics of materials! Take a small notebook and jot it down, astrologer, zoologist... add a materials scientist. 】

[So what is there that Fang doesn't know, say it at one time, let me slash my **** with a knife and open my eyes]

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

Why is ice so slippery?

Fang Shen does not know?

Question marks appear on the audience's faces, are you kidding me?

Tony thinks this is a simple question, because it is ice, so it is slippery, but when the words come out of Fang Shen's mouth, it always feels that it is not so simple, Tony raised his head and looked at his friend Peter, who he hadn't 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 the last time he was encouraged by Fang Shen, his mind has been flying. He has been doing outdoor research, and he didn't even watch Fang Shen's live broadcast.

We even set up a migratory bird website on purpose. Although there is not much traffic at present, it is indeed a good start. We also got in touch with the migratory bird protection organization to keep it updated.

This year will be the time for those migratory birds to come back. A large number of them are already on their way to migrate. Hey, I don’t know if it will be smoother this time. Those **** poachers should have died a long time ago.

"Peter? Peter!"

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

"What's wrong?"

Tony put his hand on his forehead: "What's wrong with you recently, I remember that you don't like watching Godfang's live broadcast the most? I haven't been online for star chasing the last two times. It's not right, it's very wrong, you won't be in love, right? Is it Mary from class three, or Gwen next door? It can't be Mary, but she's too teasy, you might not be able to play with her..."

Peter twitched the corners of his mouth, what is this, he and Mary are completely friendly exchanges, we are all geese lovers, there is no meaning in that respect.

By the way, there is also a photo album to give to her. Tony forgot to mention it. When Tony leaves in the evening, it will be delivered to Mary. 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.

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

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

"fool!"

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

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

【Is it not because the surface is smooth? 】

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

Damn, I'm starting to feel deprived of oxygen myself.

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

"When traveling in a broken glacier, when you encounter a crack that needs to be crossed, try to step on the front end of the alpine boots to the edge of the crack, see the edge of the crack in another section, and step across it without hesitation. It's better to use a rope to string everyone together, so that if someone accidentally falls into the ice crack, he can be pulled up without any danger, but this requires people in the team to have a high degree of execution Otherwise, there may be many situations in the area, and no matter how much you pull it up, you won't be able to pull it up."

With one face walking for more than half an hour, everyone kept crossing the cracks, big and small.

The viewers in the live broadcast room were all frightened, especially as they went on, all kinds of glaciers appeared.

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

If there are cracks at the bottom, it is even more dangerous. Two ladders are tied together, and then the two ends are placed on each other. People climb up from below. You can only hope that your teammates are reliable enough to support you.

In this situation, Bi Fang is the first to go up. This is the most dangerous, because you don't know if the rope bound to the ladder is loose. After Bi Fang goes up, you can Carry out secondary inspection and reinforcement.

"My life is handed over to you, help me."

"Don't worry." Yao Jun said OK, "I won't support the wall for three feet in the wind, I will support you!"

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

"Climbing the ladder, it is best to go up lightly, the center of gravity is more stable, wait for it to go up, and then use the rope to pull the bag up. Although this is a bit troublesome, it is better than safety."

I thought the weight was too light, plus the ladder was made up of two ladders tied together. Under the cold wind, the entire ladder seemed a little shaky and kept shaking.

When Bi Fang stepped on it and came to the top of the abyss, the drone also came over his head.

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

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

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

Bi Fang immediately hugged the long ladder, and Yao Jun also knew that he was in trouble, so he hurriedly held the ladder, but before the ladder was stable, Yao Jun opened his mouth wide and made a **** ho sound unconsciously.

There were some strange sounds mixed in the whistling cold wind.

Bi Fang hugged the long ladder and glanced around. He felt the danger, his back was chilled, and the long ladder under him began to vibrate. It was not shaking in the wind, but shaking!

The tremor gradually intensified, and the newly fallen snow slid rustling on the ice. Everyone noticed the abnormality and looked around nervously.

"Avalanche! Rob! It's an avalanche!"

Bi Fang pointed to the top of the snow peak and roared
