The weather on the snow-capped mountains is extremely changeable, and the sky is still clear, but after a while, it becomes a dark cloud, and large snowflakes fall immediately.

On the edge of a deep valley, due to the influence of the trend of the mountain peaks, strong winds blew from time to time, and in the sound of the "whirring" wind, Duan Pingsi and the three of them held hands with canes in their hands, and they barely maintained their balance.

"What the hell is this weather, it's snowing at this time, and my face is crawling like an ant!"

Professor A complained that because he happened to be walking towards the wind and snow, his long face was soon covered with snowflakes, and the snowflakes continued to turn into water droplets under the action of skin heat, which made him feel extremely itchy and uncomfortable.

Zhang Yu followed closely, observing the mountainous terrain as he walked, and sometimes looked up at the sky to see the snowflakes flying in the sky. Among the three, Zhang Yu is the most careful, and he can't hide his eyes from any hint of trouble.

"I wonder how long it will take to get there?"

Duan Pingsi, who walked at the back, said to himself, he would not admit defeat on this occasion, but this was the first time he went out for a field investigation, and he didn't expect to encounter such a harsh environment, he didn't like activities since he was a child, so his body was a little thin, and at this moment he was completely persisting with tenacious perseverance.

"Don't worry, it's going to be soon, you see," Zhang Yu said, pointing to the valley in front of him with his left hand, "We just need to climb over it and get there, and it's only about eight or nine hundred meters away." ”

Although the distance is not far, there is no road here, groping through the snow has become extremely difficult, except for the soft white snow under his feet, nothing else can be seen, Duan Pingsi has accidentally fallen his foot into some potholes several times, causing his ankle to be a dull pain all the time.

At a distance of eight or nine hundred meters, the three of them walked for a full hour, and when the huge valley that seemed to have been smashed by a boulder appeared in front of them, Duan Pingsi's legs were weak and his eyes were dazzled, and he almost fell to the ground, one because of fatigue, and the other because of shock.

Zhang Yu grabbed Duan Pingsi's hand and asked him to keep standing as much as possible, and Professor A also turned around and took his other hand when he saw this, and the two of them sandwiched him between left and right.

"The most taboo thing on the snowy mountain is to sit directly on the ground to rest, you must know that it is easy to sit down, but it is difficult to stand up again!" Zhang Yudao.

"That's right, now is the most fragile moment of the human body, only by insisting on exercise can we ensure enough calories, if you sit down to rest at this time, then the body is extremely easy to freeze, and this is the reason why many climbers can't get up and down."

Professor A looked at the sky and the valley, shook his head and continued: "I think we won't be able to go down the mountain today, so let's find a sheltered place to camp first, and then come out to have a look when the wind and snow are lighter, and now it's important to keep warm." ”

Duan Pingsi continued to walk a little further with the support of Professor A and Zhang Yu, and soon the three of them found a solid rock at the top of the valley, and they set up a tent behind it.

Professor Ah was in the tent recording some important data and charts, while Zhang Yu took out a portable stove from his backpack and burned the snow water.

At this time, the temperature was already as low as three degrees Celsius, and the snow water slowly boiled after about thirty minutes, Duan Pingsi first drank a cup, plus the warmth of the tent, and it was not long before his whole body finally warmed up.

An hour and a half later, the wind and snow stopped for a while, and while there was still some time before it was dark, Duan Pingsi and the three of them helped each other to come to the valley to investigate.

It's been more than three months since the last avalanche, and most of the cliff is already covered in snow, and only the crater that was hit is still visible.

It was a round-bottomed crater with a diameter of five or six hundred meters, as if it had been formed by the impact of a large round ball, and some trees around the crater had been burned to a pitch-black color.

"We happened to miss this place last time, otherwise we would have died here with those eighty-eight scholars!" Professor A looked at the huge crater like China's "eye in the sky", and he still had palpitations, and a sense of the aftermath of the catastrophe arose.

The group walked around the pit and found nothing of research value, and as the sky grew darker and the snow came again, they turned back to their tents.

It was night, the wind was howling outside, the snow was fluttering, Duan Pingsi and the others were tightly wrapped in sleeping bags in the tent, trying to keep the heat as much as possible in order to get a good night's sleep.

However, around half past one in the morning, some strange sounds suddenly sounded outside, breaking the silence of the snowy night:

"Da! Da! Da! ”

"Squeak! Creak! ”

"Squeak! Creak! ……”

All kinds of noises were noisy and harsh, so that Duan Pingsi and the three of them couldn't sleep at all, so Zhang Yu decided to get up and check it, although in the cold weather, it was extremely unwise.

"Oops!"

As he gently unzipped the tent, he saw a flash of fire outside, and then a black shadow fled into the valley, causing him to scream in fright.

"What's wrong with you?" Professor Ah poked his head out of his sleeping bag to look at the panicked Zhang Yu, and found that the latter had picked up a cane in his hand, as if he was facing a great enemy.

"Someone, or something, just peeked at us outside our tent, and luckily I scared them away!" Zhang Yu stared at the gap in the tent, trying to calm himself down.

"Peeping?"

Duan Pingsi asked, he didn't feel sleepy at all, one hand reached out and quietly grabbed the cane beside him, he thought that no matter whether the person who came was a human or a ghost, it could be used for self-defense.

"Don't get up, we're here, you try to keep your strength!"

As Professor A spoke, he also picked up his cane and stood with Zhang Yu, and the two of them stared left and right at the gap in the tent, trying to resist a possible attack from outside.

However, since the shadow ran away, there was silence outside, and there was no sound or light.

"It looks like that thing doesn't dare to come again, let's squint for a while!" Zhang Yu saw that there had been no movement outside, so he suggested to Professor A and Duan Pingsi.

Three hours later, there was another "click, click" sound outside the tent, and Duan Pingsi and the three of them immediately picked up their canes and rushed out, and a black shadow immediately rushed towards the depths of the valley.

Professor A looked at a series of footprints of different sizes on the ground, and said angrily: "No matter what species you are, I am bound to arrest you back!" ”

"Squeak! Squeak squeak! ”

In the distance, a mouse-like chirping sound could be heard, as if in response to Professor A's angry words.
