The snow scene is indeed very beautiful at first glance, crystal white, covered with silver, as if in a silver world, but this cold and white world looks harmless to humans and animals, but after being in the snow for a long time, there is a danger that quietly comes, that is, snow blindness.

Snow blindness is inflammation caused by the loss of ultraviolet rays to the cornea and epithelium, characterized by redness and swelling of the eyelids, conjunctival hyperemia and edema, severe foreign body sensation and pain, symptoms such as photophobia, tearing and inability to open the eyes, blurred vision during the onset of the disease, and blindness in severe cases. The reflectivity of the snow to the sunlight is extremely high, in the case of direct sunlight at noon, the reflectivity can even be as high as 95%, looking directly at the snow is almost the same as looking directly at the sun, the sun is only a point after all, and the snow is infinite, walking on the snow, the snow is dazzling, but people can not dodge.

Liu Yin has long been prepared for snow blindness, and before climbing the mountain, everyone was given some carrots, which are the first choice for preventing snow blindness, and the rich vitamins can effectively treat snow blindness.

Of course, just eating a few carrots can not completely prevent snow blindness, Liu Yin distributed a black silk scarf to each soldier, both light and thin, Liu Yin let each soldier in the noon light when the light is sufficient, the black silk scarf on the eyes, which is equivalent to each person issued a sunglasses, although the black scarf made of silk has some impact on eyesight, but in general, the effect is still very good, can effectively prevent snow light damage to the eyes.

In addition, Liu Yin also ordered the leading Wudang camp to cut some dark cloths such as black and red, and threw them along the way, which can be seen very eye-catching in a piece of white.

This is the biggest benefit of the traverser, Liu Yin understands the horror of snow blindness, and takes effective preventive measures in advance, otherwise the unknown Shu army will rush into the snow mountain. After climbing the snowy mountains, it is estimated that they will almost become blind.

The red sun gradually sank, and the first night in the snowy mountains came.

It's August, and the sun is shining during the day, but even though you're in the snow, you don't feel very cold. But as soon as the sun set, the cold wind blew, and the biting chill made people shiver, even if they were wearing a thick fur mink coat, they couldn't stop the cold wind blowing out of hell.

As soon as the sun set, Liu Yin ordered to stop the march, in addition to the cold is the biggest danger in the snow-capped mountains in the dark, those bottomless abysses are even more terrifying, and one will slide down the cliff if he is not careful. There is no place to die. Therefore, Liu Yin only ordered the march during the day, and at night the camps must choose a leeward place to camp in.

The night of the snow-capped mountains is both eye-catching and cold, the bright moon is in the sky, the cold wind is cold, and the soldiers in winter clothes are shivering from the cold even if they get into the tent, and the cold wind is like a piercing knife, inch by inch over everyone's body. On this cold night. The soldiers huddled together and snuggled up to each other. In this way, it can be warmed a little, after climbing the mountain for a day, the body is already extremely tired, but no one dares to fall asleep, such a cold place, once you fall asleep. Probably never to wake up again.

Liu Yin ordered the Huotou army to set up a marching pot, boiling ginger soup all night long, there was nothing on the mountain except snow, and the firewood that lit the fire was still carried by the men from the bottom of the mountain, and there was no shortage of water. Shovel snow into the pot on the spot and boil it into boiling water.

In order to avoid disease and plague, Liu Yin ordered that all Shu soldiers were not allowed to drink raw water, whether it was river water or snow water, it had to be boiled before drinking. Although this is more cumbersome, it can ensure that the soldiers are not infected with the epidemic to the greatest extent, knowing that with the current medical level and conditions, once infected with the epidemic, there is almost no cure, and it will bring disaster to the entire team.

Bowls of thick ginger soup with a spicy taste were delivered to each soldier in turn, and when they were swallowed down their throats, there was a burning sensation in the whole stomach, and the chill in their bodies was dispelled in an instant.

Liu Yin knew that when the Red Army crossed the snow-capped mountains, there was a lack of cotton clothes to keep out the cold, and soju and chili water almost became a life-saving talisman, but now there are no chili peppers, and the chili pepper thing is still in the fields of the Indians at the moment, and before the arrival of the Age of Discovery, there is no need to think about it. As for soju, it needs high-purity wine, and most of the people nowadays drink low-alcohol rice wine, not to mention relying on it for warmth, but I'm afraid that the more I drink, the colder it gets.

So Liu Yin thought of ginger, ginger has the effect of dissipating cold in warmth, dispelling cold and removing cold, people can take ginger soup after catching a cold can cure diseases, drink a bowl of hot ginger soup in the cold, you can get rid of the cold in the body. As early as when he was in Nanzhong, Liu Yin ordered a large purchase of a batch of ginger, which was ready to be used for backup when crossing the snowy mountains.

It was very difficult to survive until dawn, and Liu Yin ordered to set off immediately, striving to climb the first snow-capped mountain before dark.

But the climate of Jiajin Mountain has always been characterized by unpredictability, in the morning you can still see the morning sun red, the weather is bright, but in a blink of an eye, it is cloudy and indifferent, the wind rolls up the goose feathers and heavy snow, and the Shu army that is advancing towards the mountain pass is covered with a face.

The whole snow-capped mountain was shrouded in a cloud of steam, and it was difficult to find a human figure a hundred steps away, and the cold wind was howling, mixed with snowflakes, and slapped on the face, like a knife cut, and the exposed skin was frozen purple, even if it was wearing leather boots in animal skins, ten toes were numb and unconscious.

Liu Yin knew that he couldn't stop at this time, and if he stopped, people would freeze, so he took the lead in walking at the forefront of the team, braving the wind and snow, and went in the direction of the mountain pass step by step.

The commander is like this, and none of the soldiers of the Shu army have half a word of complaint, stepping on knee-deep snow, gritting their teeth, holding hands, and moving forward firmly step by step.

The closer to the pass, the more fierce the wind became, and the wind swept the snow on the ground, flying all over the sky, and the vision in front of me was blurred. Liu Yin and Zhao Zhuo walked side by side, and in front of them was Ah Jian leading a few Qiang soldiers to open the way, and the flying snowflakes almost buried them.

But Liu Yin's footsteps have never stopped, he knows that at this difficult time, he can not have the slightest stop, once he stops, the whole team will all stop, at the top of the snow mountain, the most fearful thing is to stop, once you lose the courage to move forward, I am afraid that the next step can not even take a step.

Driven by Liu Yin, the 30,000-strong army was like a white python, winding through the snow, persistently moving forward. (To be continued......)
