The core of the "Nirvana" plan is to put people into extremely harsh different environments to continuously temper and achieve the purpose of Nirvana, but there is a premise, that is, there is a preliminary contact with these terrains, and Yang Zheng is completely unfamiliar with other places except the jungle, and there is no relevant survival training.

Originally, Yang Zheng passed with the mentality of becoming a benevolent person if he didn't succeed, but the captain gave a full set of equipment out of practical considerations, although there was no weapon, but it was enough, at least there was a basic guarantee for survival, on the transport helicopter, Yang Zheng stroked the dog's leg knife in his heart, a knife in his hand, what are you afraid of?

In about two hours, the helicopter landed on the top of a snow-capped mountain plateau at an altitude of more than 6,000 meters, hovering at an altitude of 30 meters, Yang Zheng knew that the destination had arrived, put on warm gloves and hats, checked the equipment, and then threw down the rope, put on the backpack, hung the dog leg knife on the hook of the backpack, grabbed the rope and rappelled directly.

A violent cold wind blew, Yang Zheng's neck shrunk involuntarily, feeling as if a cold knife had been scraped, it was so cold, and his body shook uncontrollably, so he quickly buckled the rope with his feet, grabbed it with both hands, and made his body straight, and then his hands and feet loosened, and his body slid down.

However, the cold wind was howling, like a ghost crying wolf, and the balance of the body could not be guaranteed, Yang Zheng looked down and saw that there was a thick layer of snow below, and if he didn't go down quickly, the helicopter might not be able to stabilize, and it would be troublesome at that time, so he quickly slowed down and slid down.

Puff –

Yang Zheng fell on the snow, smashed a pit, lying on the snow, the cold breath was crazy over, like lying in a freezer, Yang Zheng was shocked, quickly got up, and saw the helicopter automatically shrink the rope and leave, Yang Zheng knew that the next road could only rely on himself.

The sky has darkened, no more than an hour before it gets dark, Yang Zheng is looking around, his eyes are full of undulating snow peaks, white and boundless, there is no end in sight, the cold wind is howling, and the terrible sound is like a demon out of hell roaring, constantly rushing towards himself.

Yang Zheng shivered coldly, feeling that the blood in his whole body was going to freeze, knowing that he couldn't stop, otherwise he would really freeze, so he hurriedly walked towards the leeward peak, the leeward slope blocked the howling cold wind, and he could live a little longer without the cold wind to take away the body temperature, standing still in the cold wind, he could freeze to death directly in less than half an hour.

Not long after, Yang Zheng detoured to a leeward hillside, walked down a distance, couldn't feel the cold wind and breathed a sigh of relief, put the backpack on the ground, and pulled out the folding sapper shovel tied to the backpack, it was about to get dark, there was no way to hurry, and he had to prepare for camping before dark, otherwise he would freeze to death.

There is snow everywhere on the snow field, there is no way to make a fire, and there is nothing to cover, the only way is to dig a snow cave, and there are many more chances to survive hiding under the snow than on the ground, before Yang Zheng didn't know how to survive on the snow field, fortunately, he watched the video before setting off and knew about the snow cave.

Digging a snow hole is not simply digging a pit, nor is it as simple as digging a hole horizontally, simple pits and holes are not advisable, and when encountering an avalanche, it is buried alive in it, very particular, time is pressing, Yang Zheng picked up the sapper shovel and dug it up quickly, fortunately it is all snow, without too much effort.

It didn't take long for Yang Zheng to feel out of breath, shortness of breath, unable to do anything, knowing that it was altitude sickness, it was introduced in the video, Yang Zheng had to stop and rest, took off the hanging military pot from the backpack, and felt a little heavy in his hand, and couldn't help but be overjoyed, opened it to see, it was really water, but he didn't expect the captain to help load the water before leaving.

Yang Zheng opened it and took a sip, and found that it was still hot, Daxi, drank a few more sips, the warm current went down the esophagus into the stomach, a warm current spread out all over the body, and felt that some coagulated blood began to flow, Daxi, quickly covered the lid to keep warm, and was grateful for the captain's care.

After a short rest, Yang Zheng felt that his breathing was more stable, picked up the sapper shovel and continued to dig, this time he didn't dare to be too fast, although it would be very dangerous when it was dark, but altitude sickness could also kill people, Yang Zheng controlled the speed and dug slowly.

Unconsciously, a pit about one meter eight long, about two meters deep, and about three times the width of his body was dug well.

Ten minutes later, Yang Zheng saw that the sky was getting darker and darker, a round of the moon hung high in the moon sky, it was about to get dark, did not dare to delay, dug to the side about half a meter above the ground, and the snow dug out was shoveled out, and after more than ten minutes, he finally took out an ice platform that was more than one meter deep and about half a meter high.

The ice platform is like a bed platform, because it is about half a meter higher than the snow pit, the cold air comes in and sinks at the bottom, and people will be much better on the bed platform, of course, the human body temperature will make the ice and snow in the snow cave melt, and the melted water will be quickly frozen by the cold air, so that the snow cave will expand, expand, and the activity space will shrink, but the width of the entire snow cave is more than three times that of the human body, so there is no need to worry about squeezing after expansion and expansion, and burying people alive in it.

Ice and snow because the body temperature melts and freezes quickly, resulting in a narrower space, the pit is too small, it will definitely die, too big is not good, it cannot form a constant temperature, the body temperature will be diffused, the best width is three times the body, the length is determined according to the height, the depth can be larger, the deeper the cold air sinks to the bottom, the less it affects the bed.

Yang Zheng rested for a while, and smoothed the ice wall on the bed with a sapper shovel to prevent the ice and snow from melting after the temperature came up, and dripping down the raised part, and the melted water would spread after smoothing, and it would solidify before the water droplets were formed.

It's dark. Yang Zheng finally made the snow cave before dark, the time was still early, not in a hurry to sleep, Yang Zheng squatted in the snow cave and opened the rucksack to check the equipment, and found that in addition to the sun hat and goggles, there were moisture-proof mats, sleeping bags, strong flashlights, first aid kits and a bag of compressed biscuits.

Yang Zheng was overjoyed, put the lighter and salt close to the body into the rucksack to avoid throwing it away, took out the moisture-proof mat and spread it on the ice bed, and then took out the sleeping bag and put it away, this special zipper type sleeping loan is the most convenient, go inside, and then pull the zipper, the whole person is wrapped in it, very warm.

With these equipment, Yang Zheng estimated that he had about a thirty percent chance of survival, and his heart was determined, compressed biscuits were life-saving materials, and they must not be used until the last moment, Yang Zheng squatted for a while and felt that his whole body was going to be frozen, so he was shocked, and quickly took off his coat and shoes and got into the sleeping bag.

Staying still on the snow field, the blood in the body is easy to coagulate, especially the hands and face, this kind of frostbite can only amputate the limbs, the horror of the snow climate of dozens of degrees below zero, people who have not experienced it are unimaginable, not to mention people, even the steel can be frozen for a long time.
