The next morning, at six o'clock in the morning, Chen Nan had already woken up. With the yellowish light of the kerosene lamp, Chen Nan carefully studied the map. The route on the map was not very clear, and the scale was not very clear.
Accurate, we still need to start early. Chen Nan wanted to see if there was snow outside through the window, but there was a thin layer of ice on the window and he could not see the outside environment.
Chen Nan shrank into her bed again. Hey, getting up is always the most difficult thing.
After the sky was completely bright, Chen Nan was ready to go. He opened the door and took a look. To be honest, the weather today was not very good. The wind was not strong and it was lightly snowing. The temperature displayed on the watch was minus seventeen degrees, which is not very hot.
It's cold, mainly because there is no fog today, and the view is very good. You can vaguely see an orange lighthouse on the top of the mountain in the distance.
After taking a final inventory of his equipment to make sure it was correct, Chen Nan hit the road. The snow fell very thick last night, at least about half a meter deep. There was originally a railway outside, but it is now completely covered.
, his eyes were all white. Chen Nan pulled his hat down a little, slightly blocking some of the viewing angles. In this environment, Chen Nan didn't want to suffer from 'snow blindness'.
Chen Nan once saw in the news that mountaineers and scientific expedition team members who were active in high mountain glaciers and snow-covered areas were not careful and forgot to wear sunglasses. Their eyes were often stung by the reflection of the snow, and they even became temporarily blind. Medically speaking,
This phenomenon is called "snow blindness".
Snow blindness is a disease that causes temporary blindness after the retina of the human eye is stimulated by strong light. Generally, vision will recover on its own after a few days of rest. People who have suffered from snow blindness will develop snow blindness again if they are not careful. The symptoms of snow blindness will be more serious again, so
Don't be careless. Repeated snow blindness will gradually weaken your vision, causing long-term eye diseases, and even permanent blindness in severe cases.
Snow has a high reflectivity to sunlight. The so-called reflectivity refers to the ability of any object surface to reflect sunlight. This reflective ability is usually expressed as a percentage. For example, if the reflectivity of an object is 45%, this means
It is said that 45% of the solar radiation received by the surface of this object is reflected. The reflectivity of snow is extremely high, and the reflectivity of pure new snow can be as high as 95%. In other words, 95% of the solar radiation is reflected
The snow surface reflects again. At this time, the snow surface is almost as bright as sunlight. How can the retina of the naked eye withstand the stimulation of such strong light?
There is no fog today, the sun is bright, and the temperature is very low. If you get this kind of disease here, there is absolutely no eye hospital. In the whole morning, Chen Nan hardly walked much, covering a distance of five or six kilometers.
, due to various reasons, the speed is very slow, and a wolf howl is heard in the distance, which sounds very permeable in this quiet environment.
Chen Nan didn't know how far he still had to go. After noon, the sky gradually darkened. Looking at the clouds in the sky, it seemed that it was another snowy day. He chewed a piece of cake that had been baked for a long time.
Although there is no salt added to the cooked fish, it still tastes a little salty. However, after a morning's work, it was still very tough, and the soft dried fish had become hard, so you could only hold it in your mouth.
Chew slowly before you can eat it. If you eat it directly, it will definitely not be digested.
At two or three o'clock in the afternoon, the color of the sky was completely different. The temperature had reached about minus 25 degrees. Ice crystals appeared on Chen Nan's face and clothes. His fingers were slightly purple, and his upper and lower rows of teeth were also wet.
He was fighting, his body was shaking constantly, but his steps did not stop.
"He... he's... he's... what the hell kind of weather is this? It's freezing... it's freezing me to death." Chen Nan cursed loudly. Because of the cold, it was difficult to speak, but it gave him hope.
, is a red staircase leading to the top of the mountain not far away. This staircase can be seen not far away. It surrounds the mountain. You can go to the top of the mountain through the stairs. Chen Nan's system is displayed in red at this time. It has
Completely exhausted, with only the last quarter of his mental value left, Chen Nan can no longer run, and his walking speed has become very slow.
At a distance of two hundred meters, it took Chen Nan a full five or six minutes to reach the orange-red staircase. This staircase was made of steel and was very strong. Chen Nan held on to the handrail of the staircase, which was also covered with a layer of
Snowflakes, it is much easier to go up the stairs than on the ground. I thought that there were not so many snowflakes on the stairs, just a shallow layer. However, Chen Nan was still very tired. He felt that his backpack was extremely heavy, so he threw it directly where it was.
He only had a key in his pocket and a piece of flint, which was enough.
After throwing away his backpack, Chen Nan went up the mountain much faster, but it still took a full hour. At this time, there was already a violent snowstorm outside. Chen Nan was almost blown off the cliff several times, and the palms of his hands were
The skin has cracked, but no snow flows out, because the environment is too cold and the blood coagulates too quickly, but this coagulation is not a good thing. If not treated properly, the mountain pass on the hand will become infected, even if it is
In this temperature, you still have to be careful.
When he walked to the door of the watchtower, Chen Nan found that the metal key in his hand was tightly stuck to his skin. After Chen Nan took the key off, he tore off a piece of skin, but Chen Nan did not
He felt no pain, as if he had turned into a zombie. The corners of Chen Nan's mouth twitched. He knew that when he warmed up, the severe pain in his hands would double on his body. After opening the door, inside
The temperature rose instantly, and the temperature indicator that was still there is also rising.
The temperature here is minus 5 degrees Celsius, while the temperature outside has already reached minus 30 degrees Celsius. When the blizzard really starts to take off, minus 40 to 50 degrees Celsius is normal.
As expected, there is firewood here. I don’t care about anything. Now there is a frostbite alarm. There are varying degrees of frostbite on my hands, feet, and legs. The most important thing is to warm up first. There is a potbelly furnace in the room.
It was quite good. There was a lot of charcoal in it. Chen Nan found a book and tore it into pieces. He then used a lighter to light the scraps of paper and watched the flames gradually rise. The temperature inside the house,
Finally getting warm again, Chen Nan fell asleep unknowingly in front of the stove, and his energy level was completely exhausted at this time...
