"This snow has fallen before, it has not melted, and it has accumulated over time to form snow-capped mountains." Zhang Wei explained.

"Why doesn't the snow melt here?"

"Because it's so high."

"Platoon commander, what is altitude?"

"Oh, it's just too high."

"Platoon commander, I still don't understand, why the terrain is high and the snow doesn't melt, it stands to reason that this place is closer to the sun, it should be easier to melt, you see the sun just doesn't melt." Zhang Shun said.

"It's all common sense, and it's in middle school geography textbooks: in the mountains, the temperature drops with altitude. Roughly every 100 meters above sea level, the temperature drops by 0.6 °C, now the altitude here is at least 4000 meters, more than 20 degrees lower than the temperature under the mountain, and now the temperature is at least minus 178 degrees, such a low temperature, the snow in the sky will definitely not melt. Zhang Wei patiently explained.

"Oh, it turns out that it's all in the textbooks, but it's just that I didn't go to school properly." Zhang Shun said.

As the mountain became steeper and steeper, the team members began to slip and fall while walking, and it became colder and colder, and the hands and feet became cold.

The road became more and more slippery, and sometimes one step back would lead to three steps, and the team members had to pull out their military thorns to help.

Suddenly, the person in front stopped and didn't leave, Zhang Wei hurriedly walked over to see what was going on, it turned out that a team member accidentally slipped into a deep ditch dozens of meters deep, he tried several times to climb up, but all failed.

Zhang Wei secretly blamed himself, he should have talked about the precautions before climbing the snow mountain, otherwise there would be no team member to slide down, and now he must find a way to get him up, if he is left alone, he will be eliminated.

But now everyone is a competitor, and eliminating a player is equivalent to one less competitor, so should you save him?

"Everyone, take off the backpack straps." Zhang Wei said put down his backpack, first untied his backpack belt, now is a special period, everyone is a collective, as long as it is a member of the collective, it must not be abandoned, the backpack belt was thrown down the ravine, the rope is not enough to put it halfway up the mountain, Zhang Wei took the backpack handed over by others, and connected the two together, and the backpack belt barely hung down to the side of the team member.

The team member saw the backpack strap and hurriedly reached out and grabbed it despite the injuries on his body, like a drowning man grasping a life-saving straw in his dying, he grabbed the backpack strap and tried to climb up, but it was too slippery, his feet just slipped in place, and although he tried a lot, he still didn't come up.

"Come, let's all pull him up together." Zhang Wei said.

Several team members heard the greeting and came over and dragged the backpack strap together, and the team member who fell down was slowly pulled up, and he sat on the snow with his butt after coming up, frightened, fortunately someone saved him, otherwise, if he froze to death here alone, no one would know.

"Comrades, it's all ice up there, everyone must pay attention, for the sake of insurance, let's all tie it together with backpack straps, so that someone can avoid falling into the ditch." Zhang Wei said to everyone.

After listening to Zhang Wei's words, everyone tied them together one by one, and then continued to move forward. Although some people kept slipping and falling while walking, due to the rope pulling, the slippery team members quickly stood up, and everyone stepped on the ice and snow road that the team members in front of them waded on, one by one, and groped their way up on the winding and rugged snow road.

Now everyone is really a grasshopper tied to a rope - no one can do without anyone.

The higher you climb, the steeper the mountain, the thicker the ice, the more slippery it becomes, and the higher you climb, the colder the weather becomes, the thinner the air, and the greater the physical exertion of people.

Suddenly the wind rose, and the wind blew more and more tightly, the wind blew on the face like a knife, a mouth, the cold wind drilled into the mouth, blowing for a long time, and after a while, there were snowflakes, and the snow fell more and more, and the soldiers all became snowmen.

The whole formation was like a silver snake, moving slowly on the snowy mountain.

The higher they climbed, the steeper the mountain became, the more slippery the road became, and many of the warriors lost sensation with their feet frozen, and even fell with one step, and if there was no rope to pull them, I am afraid that they would have to slide into the valley again.

Now the team members are hungry and cold, and some of them simply dismantle the quilt and put it on their bodies, even so that they are shivering all over the body, if it weren't for the many people encouraging each other, they would have stopped climbing a long time ago.

Now I finally realize the hardships of the Red Army's climb of the snow-capped mountains, they were all wearing single clothes and even straw sandals to climb the snow-capped mountains, I really don't know how the predecessors came over in such a difficult environment?

"Platoon commander, why am I a little dizzy." Zhang Shun asked.

"You have a fear of heights, be careful not to look back, you look ahead, you are about to reach the top of the mountain, hold on for a while." Zhang Wei reminded Zhang Shun.

"Platoon commander, I didn't look behind me at all, I just felt dizzy, chest tightness, and wanted to vomit, platoon commander, I couldn't walk anymore." Zhang Shun said.

"Oh no, you're definitely mountain sickness right now."

"Platoon commander, what is altitude sickness?"

"When people in the plains climb high mountains, due to the thin oxygen and reduced air pressure, they will produce vomiting, tinnitus, headache, shortness of breath, loss of appetite, fever, drowsiness, and in severe cases, there will be dull sensation, restless mood, high spirits, decreased thinking and memory, abnormal hearing, sight, smell, taste, hallucinations, etc., and may also occur edema, shock or spasms. Looking at your current condition, it meets several items, and eighty percent of them are suffering from altitude sickness. Zhang Wei said.

When the two were talking, news came from the front that someone had fainted, and Zhang Wei told them that they were mountain reactions, and asked the people in front to find a way to lift them all up, and no one could be pulled down.

"Platoon commander, I can't do it anymore, my legs are a little weak, I'm going to fall." When Zhang Shun heard that someone fainted in front of him, he began to be timid in his heart, and he had no confidence when he was timid, and he had a fear of heights, so he was about to go limp when he spoke.

"Zhang Shun, hold on." Zhang Wei hurriedly went to help Zhang Shun, but as soon as his foot slipped, he slipped and fell with Zhang Shun, he crawled over and hugged Zhang Shun, only to see Zhang Shun's face pale, foaming at the mouth and not waking up, and the marching team was forced to stop.

"235, do you want to ask the command for help when so many people have fallen?" Liu Ci asked.

"No, they're just a temporary alpine reaction now, and they'll be fine in a while, if they report to the command, they'll be finished, and they'll hate us to death when they wake up." Zhang Wei said.

"But if we don't report it now, they will become a burden to us, and we will be tired of them sooner or later." Liu Ci asked.

"Lift them over, we can't abandon any of our teammates, come, Liu Ci, you lift your legs, I raise my head, let's lift Zhang Shun over."

"Okay, let's carry him over together." Liu Ci said.

In this way, Zhang Wei and Liu Ci lifted Zhang Shun and continued to move forward, but they didn't expect that just after walking a few steps, the three of them fell together, and after being fallen, Zhang Shun slowly woke up, and saw Zhang Wei and Liu Ci's anxious faces, he said weakly: "Platoon commander, let's go, don't let me burden everyone." ”

Zhang Wei said: "Zhang Shun, don't say stupid things, it's all come to this point, we won't leave you alone, even if we pull you and pull you across the snowy mountain, Liu Ci, come, let's pull him away." ”

"Okay." Liu Ci walked to the front, and the two pulled Zhang Shun to walk, and the team began to move forward little by little.

The team members in front had already begun to climb over the snowy mountains with difficulty, and the team members in the back also climbed over the snowy mountains one by one, and when everyone had all crossed the snowy mountains, they all sat on the ice exhausted one by one.

Because the mountain is too steep, the team members can't stop sliding down when they sit on the ground, so they just don't do it and slide down, and the people in front mention it, and the people in the back immediately agree.

In this way, everyone sat in a row one after another, and with a gentle push from the people behind, everyone slid up the mountain, sliding down the mountain like a rattlesnake.

Not to mention, this is really a good way, when climbing the snowy mountain, it took a full four or five hours, and when it went down the snowy mountain, it took half an hour to come down.

After arriving at the place where it couldn't slide, the team members stood up, looked at each other's butts, and the camouflage uniforms and pants they wore were all ground into a big hole.

When he arrived at the foot of the snowy mountain, Zhang Shun slowly eased up, his body recovered quickly, and he could run with everyone again.

The bottom of the mountain became a plain, and it was simply a flat river, which was so flat that it had been wiped with a mud trowel, and a layer of dry grass grew on it, and finally it was over the mountain, and now it was time to cross the meadow.

"We've climbed the snowy mountains, we've climbed the snowy mountains!" The members of the team in front shouted excitedly and ran down, but they didn't expect the grass under their feet to be soft, and when they stepped on it, they only heard a few shouts of "oops, oops", and saw that the members in front of them fell into it one by one......

Several members of the team who ran in front had just stepped into the grass, and their feet sank in, and before they could pull it out, they only heard a muffled sound of "bang", and something exploded under the silt, and suddenly the mud splashed, and the few in front were so frightened that several rolled and crawled out.

Boy! After a long time, there was still thunder buried under the mud.

Thor walked over and sniffed around, but didn't smell any explosions nearby, so he found a stick and inserted it diagonally into the mud to test the depth of the silt.

Hearing the explosion, Zhang Wei hurriedly ran over, and when he saw Thor testing the depth of the mud, he asked, "Thor, what happened to the explosion just now?" ”
