We very much agree with the method of big talk, which is more in line with the natural law of "sunrise and sunset". It's just that here the laws of nature are not so regular: the days become longer, and the nights become shorter. With such a natural law in mind, we can only take advantage of the daytime to move forward as much as possible.

Seeing that everyone was almost ready, the big man urged everyone to go on the road together. Several of us were afraid that "change will happen later", so we immediately set off in full gear and looked at the vast snow-capped mountains without a moment's hesitation.

As the saying goes, "looking at the mountain and running down the horse", although looking at the snow-capped mountain is right in front of you. However, it will take some time to get there.

The old ghost looked at those snow-capped mountains and said a little dejectedly: "I'm sorry, big guy, it's not me who said discouragement, looking at the endless snow-capped mountains in front of me, I think it's not easy for us to get there!" Especially Fang Yu, don't be upset when you hear me say this. It is said that Mount Everest is the 'roof of the world', and the altitude is the highest place in the world. It's easier said than done to get to the top, but to put it mildly, you just don't know whether to live or die! ”

Of course I was a little upset to hear the old ghost say that. However, he was telling the truth. Even if he doesn't say it, that's what we're going to face.

Qian Cheng, who was on the side, said: "Since everyone is here, don't say these disheartening words anymore, there is no point in saying them." ”

I just wanted to follow Qian Cheng's words, but I stood up to the old man and said, "This little money is not wrong at all!" "If you come here, you will be safe", since you have arrived here, stay here with peace of mind, and don't say some meaningless words. Unless, if you quit now, it's too late. Besides, we didn't say we were going to Mount Everest! ”

The old ghost listened to the old man's words. He hurriedly said in surprise: "Huh? It's not going to Mount Everest, so where are we going? ”

"The ice cave and the thousand-year-old snow lotus we are looking for are not on Mount Everest, but in an ancient cave. That ancient cave is between the Fairy Peak and another Fairy Peak, in a very secluded Grand Canyon. The old man said.

"Oh, I'm relieved when you say that!" The old ghost said with relief: "I thought we were going to Mount Everest!" At such a high altitude, he is a professional mountaineer who has not undergone professional pre-training. It's also impossible to get there lightly. Since I'm not going to Mount Everest, I'm not so worried. ”

"Not necessarily! Don't overthink it, in fact, the Grand Canyon between these two fairy peaks is so dangerous that we can't imagine. Although the altitude is not as good as Mount Everest, it is not worse than there in terms of dangerous journey. The old man said sternly, "It's better not to take it lightly!" ”

Hearing what the old man said, the big man on the side also nodded and said, "Well, what the senior said is not wrong at all!" We must all be vigilant. Always ready. Along the way, we don't know how many things happen that we can't imagine, and we can't predict them! I won't say much about the rest, it's useless to talk more, it will only increase the psychological burden, and we still need to hurry. ”

In this way, led by the big man, we marched all the way to a higher altitude. Initially. We could also see scattered woods as far as we could see. However, with the gradual increase in altitude. There is less and less vegetation to see as far as our eyes can see.

Because as the number and the number of targets decreases, our eyes become more and more strained. The pressure on our vision was getting bigger and bigger, and we had to wear sunglasses. But what we didn't expect was that the symptoms of snow blindness gradually appeared.

Snow blindness is a condition in which the retina of the eye is stimulated by bright light, causing temporary blindness.

Snow is extremely reflective of sunlight of almost 95%. Looking directly at the snow is like looking directly at the sun, as this symptom often occurs in mountaineering, snow and polar explorers. Hence the name "snow blindness". Similar symptoms may occur in welders who are not wearing protective devices.

The way to prevent this is to wear UV-blocking sunglasses, lenses with polycarbonate or CR39, or full-face grey glasses with frog lenses. If possible, supplement with vitamin A, vitamin B complex, vitamin C and vitamin E.

In writing, if you have symptoms of snow blindness, you can cover your eyes with an eye patch and clean gauze. Don't force your eyes. And try your best to seek medical attention.

Snow blindness is a short-term symptom, though. The symptoms of snow blindness can be recovered within 24 hours to three days.

In fact, walking in the snow is a very dangerous thing: it is very easy for people to suffer from snow blindness, lose sight of the route and lose the direction of travel.

As a result, many people think that it is because the sunlight reflected by the snow is too strong. Actually, strong light only causes damage to the eyes, and snow blindness is not caused by it. Therefore, wearing sunglasses can also cause snow blindness. That's when I remembered the real cause of our symptoms now.

An authoritative study in the United States has concluded that the main factor that causes snow blindness is that there is nothing in the snow! Scientists have proven that the human eye is always tirelessly exploring the world around them, from one landing point to another. If it takes too long to retract and not find any of the landing points, it will go blind due to nervousness.

The U.S. Army found a way to deal with snow blindness by sending pioneer troops to plant darker flags on the march in advance. In this way, eye-catching signs appear in the endless snow. The search of the human eye has a landing point, so that the optic nerve will not be tense due to the long-term blank and cause blindness.

The snow was still falling overhead......

Strange to say, at a high altitude, the sight before us was magnificent: above us, there was a dark cloud, and snow was falling from above. What is especially beautiful is that there is a gold border on the edge of the large black dark clouds, which looks very spectacular.

In the distance of the dark clouds, there were clear skies and sunny days. From time to time, clouds drift by, casting a swift shadow in the sunlight. The contrast between the blue sky and the snow-capped mountains is an indescribable beauty.

The others were almost always looking at the road in front of them, barely noticing the view. I looked at the scene in front of me, which seemed to be two worlds, and said to Duoduo, "Look, this kind of beauty is not something that you can see very often!" (To be continued......)
