In the dark live broadcast room.

Lu Yu's voice was loud.

It sounds like he's in pretty good shape.

It's just that the breathing sound is a little rapid.

Seeing this situation, the audience finally relaxed.

Anyway, at least for now, he's safe.

Continuing the topic just now, Lu Yu said slowly into the camera: "This thing is my saliva." ”

Saliva?

The audience didn't understand his words very well, so they asked:

"What the hell is saliva?"

"Saliva?"

"WTF!

"It can't be another routine, right?"

"It was really thrilling just now!"

"It's terrible, I haven't recovered yet!"

The message of the barrage circulated in my mind.

Lu Yu took out a Swiss Army knife from his trouser pocket, cut off the buttons of the down jacket cufflinks, and put them in his mouth.

Then, it continues:

"That's right, it's saliva. ”

"I'm wrapped up in snow now, and I can't tell the difference between up and down, left and right. ”

"If you want to determine the direction, the only way is to quickly get your mouth and let my saliva flow down the corners of my mouth, so as to judge!"

"Due to the influence of gravity, whether it is on a plateau or a flat ground, the liquid will always flow downward. The direction of saliva directly determines the direction of my escape. We just had to dig a snow trail in the opposite direction and we would definitely be able to escape. ”

Hearing this, the audience suddenly realized!

It was immediately understood.

Actually, the principle is very simple.

It is nothing more than using gravity to determine the direction.

When a person's whole body is wrapped in snow, the body's gravity sense will be completely ineffective.

It's not easy to pinpoint the exact bearing.

However, by using the flow direction of saliva, you can accurately distinguish whether the escape direction is correct or not.

"I've got a button in my mouth, and this thing helps me get into it quickly and accumulate a lot of saliva!"

I have to say.

Even if he is under siege, Lu Yu's escape ideas are still very clear.

Every detail, handled almost perfectly!

In times of crisis, he can still be so calm, and his strong psychological quality can be imagined!

If it was really an ordinary person.

Not to mention these details, even the fear in the heart may not be able to be effectively overcome!

"Damn, awesome!"

"666, the clarity of thought is terrifying!"

"If it were me, I would have been scared to pee!"

"The psychological quality of the anchor is really strong!"

"I don't have any real skills, and I don't dare to die like this!"

"The button is amazing, and the posture is up!"

......

In fact, when encountering an avalanche, the most important thing is to be calm.

Don't panic.

Because of the huge psychological pressure, it will not only consume physical energy, but also make you fall into despair in an instant.

Very undesirable.

Because of the buttons in his mouth, it didn't take long for Lu Yu's mouth to secrete a large amount of saliva.

In the dark, he slowly opened his mouth and put his hands in front of him, allowing saliva to flow naturally from the corners of his mouth.

As expected, the saliva did not fall on the injury, but on the face.

So at this moment, I should be lying on my back on the ice.

Face to sky.

As long as you follow this direction, you will definitely be able to escape from the thick snow.

"Now that I've got my bearings, my saliva is running down my face. ”

"So now, I'm supposed to be facing the sky, with my back to the ice wall......! Luckily, this avalanche was not a wet avalanche, but an airborne avalanche, mostly a soft, powdery layer of snow that wasn't too thick and not that tough. ”

"A blessing in misfortune. ”

As he spoke, Lu Yu unfastened the safety buckle around his waist, cut the climbing rope with a knife, and pulled out the ice axe.

Then, with repeated waves of his arms, he spared no effort to dig through the snow in front of him.

Once you have an accurate bearing, you don't have to worry about it.

The next thing to do is to use the strength of the milk and dig desperately upwards until the end.

At the moment, the snow is not yet fully compacted, and digging is not a problem.

In the blink of an eye, the space for activity is getting bigger and bigger.

Soon, the audience finally saw the light on Lu Yu's headlamp.

In sight, the narrow slope can only accommodate the next person lying flat in it.

It's very cramped.

For claustrophobic patients, this picture is simply torture.

"Claustrophobia Benefits!"

"Damn, I feel like I'm going to suffocate!"

"I don't feel angry when I come up—"

"Have you seen a movie, it's called being buried alive, and the whole process is depressing!"

"Brothers, hit 120!"

......

Soon, 10 minutes had passed.

The slopes are getting bigger.

In the middle of it, you can already stand up completely straight.

Unlike before, Lu Yu could clearly sense that his breathing was getting smoother and smoother.

The cold air penetrates through the snow and into the nose, giving you a feeling of rejuvenation.

Live stream.

Lu Yu continued to say while expanding his activity space by taking advantage of the dim light:

"Many sources have pointed out that people who are completely buried can survive for about 20 minutes. ”

"But that doesn't mean we can stay in the snow for so long. ”

"Although the snow cover is porous and contains a lot of oxygen. But in many cases, while absorbing oxygen, the victim will continue to inhale the exhaled air, and over time, there will be a high probability of causing carbon dioxide poisoning. ”

Carbon dioxide poisoning is a deadly threat.

It can cause reflex respiratory arrest, resulting in sudden death.

In many cases of avalanche death, almost 50 percent of people die from carbon dioxide poisoning.

It may seem like nothing, but in fact, it's terrifying.

It is precisely for this reason that after determining the direction of escape, you must do everything you can to expand your living space in the snow!

The more space you have to move.

The greater the amount of oxygen will also be entered.

At that time, the concentration of carbon dioxide will naturally drop to normal levels.

"There's one more thing besides carbon dioxide that threatens you deadly—"

As the words fell, the drone's lens turned to the inner wall of the slope.

At this moment, the inner wall, which was originally soft, has formed a thin layer of ice.

Under the glitter of the lights, it shines brightly.

"When you're digging a slope, the hot air you exhale causes the snow to melt quickly, causing the snow to freeze again, turning it into a solid, non-porous layer of ice that oxygen can't easily penetrate. ”

"This is also a key point that leads to hypoxia and cannot be ignored. To avoid this from happening, be sure to breathe away from the inner walls of the slopes. ”

The floating snow of the avalanche will slowly move down the ice wall for a long time.

Some will cling to the ice.

Others are deposited beneath the ice wall.

It is the daily avalanches that create this incomparably large and terrifying plateau glacier.

So, as a rule, the snow in the upper half of the ice wall is not too thick.

But in the blink of an eye, nearly half an hour has passed, but it has not yet reached the end.

After digging for a long time, Lu Yu's arms were sore and swollen, and his physical strength was almost exhausted.

If you still can't get through the slopes, the consequences are really serious.

For a while, not only Lu Yu, but also the audience was worried!

The next second.

When he was physically and mentally exhausted, when he swung his ice axe again, countless snows suddenly fell from the top of his head.

"Boom la la ——!"

Immediately after, the deep and dark sky came into view.

Got through?

Seeing this, Lu Yu's spirits were lifted, and he hurriedly cleared the snow around him, and then said excitedly to the camera: "Hey, friends, look at what this is!"

The moment the drone was aimed at the night sky of the plateau, the audience in the live broadcast room was dazzled and imprompted!

"Damn!"

"Awesome! I really escaped!"

"The feather god is here, no surprise!"

"Finally breathe a sigh of relief!"

"Escaped!"

Compacting snow near the pistes.

Lu Yu put the ice axe on his waist, then took a breath, and sighed again and again at the camera:

"Whew, it's really not easy to see the sky again after a long absence......
