"The premise of hiding behind the dunes is that the direction of the sandstorm appears on the left and right sides of the dunes. But most of the time, sandstorms in the desert will appear on the windward side of the dunes. It's obviously a northwesterly wind right now, and if I hide behind the dunes, I'll end up buried alive. ”

"If you encounter a situation similar to mine in the desert in the future, you can use this method to avoid sandstorms. ”

Ye Xuan said, walking quickly to the right. On the right is a vast flat sandy area, and there are no sand dunes within 100 meters of the surrounding area.

Coming to the flat sand, he put down his backpack, squatted on the ground, stretched out his hands and quickly dug up the sand, "No one knows how big the sandstorm will be and how long it will last, so the nearby sand dunes are likely to bury you underneath in the process of moving." So in the absence of cover, it is best to find a relatively flat and wide area. ”

"Then, you'll need to dig a bunker like I did, and you'll be able to lie down in it. Ye Xuan continued while digging the sand quickly: "Remember, don't dig too deep in the sand pit, as long as you can ensure that after you lie down, it is enough to be about 5 centimeters below the horizon. This allows you to avoid the high-speed flying sand in a sandstorm without burying yourself deep underneath. ”

Fortunately, the sand is very soft, so it doesn't take much effort to dig at all. However, it took Ye Xuan a full hour to finish the sand pit.

At this moment, a sand pit 2 meters long, one meter wide, and 30 centimeters deep appeared in front of him.

The wind was getting stronger and stronger, and countless tiny clouds of sand and dust were lifted up one after another, filling the air, making the whole sky look hazy.

To be honest, digging this sand pit is much more tiring than expected, Ye Xuan sat by the sand pit, panting, "Now that the wind is getting stronger and stronger, the sandstorm is coming soon, and I still have one last bit of preparation to complete." ”

Although it was already more than seven o'clock in the morning, the temperature was still hovering around zero degrees due to the raging cold wind.

As soon as the words fell, Ye Xuan quickly took off his jacket. The dry and biting cold wind suddenly made him shiver, and a layer of goosebumps rose all over his body.

Struggling to control his right hand, which was trembling slightly in the cold wind, he took out the dagger, and once again cut almost half of the fabric from his T-shirt. After putting on the jacket again, the warm feeling made him breathe a sigh of relief.

I have to say that more than 2,000 pieces are worth it. This jacket has a very good cold resistance effect, and the style looks a little thin, but in fact it is a three-layer structure, the first layer is waterproof, the second layer is windproof, and the third layer is warm, which can preserve body temperature to the greatest extent. However, the only drawback was the lower body, and due to financial reasons, he could only buy a pair of hiking pants for one or two hundred yuan casually.

In this environment, lightweight, breathable hiking pants simply cannot provide effective warmth. Let his legs tremble in the cold wind.

"Generally, after a sandstorm, there will be countless high-speed moving sand and dust floating in the air, which will cause great damage to people's respiratory tract and lungs. The vast majority of people who die in sandstorms do so because of severe damage to their respiratory tracts, which eventually leads to suffocation. So, be sure to protect your nose and mouth. ”

The half of the T-shirt fabric was folded layer by layer by Ye Xuan to form a simple mask, "The effect is definitely not as good as that of professional masks, but it's better than nothing." When everything is ready, just lie quietly in the bunker and wait for the sandstorm to pass. ”

"It's best to pray in your heart that this sandstorm is not large. At the end, he added.

Dust storms are classified into four levels according to wind speed.

Sandstorms with wind speeds of Category 4 and 6 are not very strong and do not last too long.

However, once the wind speed exceeds 9, it is a strong sandstorm, and the instantaneous wind speed often exceeds 100 kilometers and can last for several hours.

The most terrifying thing is the extremely strong sandstorm, which is commonly known as the black storm.

Black storms usually last for a day or two, during which time visibility is almost non-existent, and the storm that obscures the sky can turn day into night.

The country's largest black storm in recent years occurred in June 3, when 83 people were missing, more than 500 were killed and more than 4,500 were injured. You know, this is still a city on the edge of the desert, and if it is in the desert with the strongest storm, how terrifying it will be!

To survive in the wilderness, luck also plays a role.

Ye Xuan didn't expect much luck from him, he just hoped that his luck would not be too bad, just meet the black storm.

He has no fresh water reserves now, and once he encounters a black storm that lasts for a day or two, he is estimated to be dying of thirst before he can be buried alive.

The gale gradually turned into a strong wind, and the drone was in mid-air, flying up and down, swaying from side to side, and would fall at any time.

Seeing this scene, Ye Xuan hurriedly took out the remote control and controlled the drone to land slowly.

He quickly stepped forward to pick up the drone, and was about to put the drone back into his backpack, but as soon as he raised his head, the whole person was suddenly stunned.

In the distance in front of him, at the end of the horizon, there was a wall of sand that stretched for an unknown number of kilometers, quietly appearing in the sky.

The sand wall is so high that it seems to connect the ground and the sky, sweeping in like a raging tide, with the power of swallowing everything.

Dust storm!

Here it comes!

It wasn't until this moment that Ye Xuan truly realized how small people were in front of nature.

It's approaching eight o'clock now, and most of the audience has woken up by the moment. After entering the live broadcast room, they were shocked by the scene on the screen.

"Nima, what's going on!"

"When you wake up, it's the end of the world?"

"it, sandstorm. ”

"The patriarch's crow's mouth, there's something. ”

"It turns out that the sandstorm is so spectacular. ”

"Good boy, it's so exciting early in the morning. ”

"It's not in vain that I got up so early to watch the live broadcast, just like the blockbuster in the United States, the thief chicken is exciting. ”

"Nuclear energy ahead!"

Unlike recorded video, the biggest advantage of live streaming is its unique realism.

Whether it's the anchor or the viewer, you never know what will happen in the next second, and this is precisely the most attractive part of live streaming.

The speed of the sandstorm was fast, and in just a few minutes, it was coming from the horizon.

Ye Xuan swallowed with difficulty, and after coming back to his senses, he hurriedly turned off the drone and stuffed it into his backpack.

After taking out the kettle and taking a sip of water, he did not swallow it immediately, but took it in his mouth, and then tied the folded cloth firmly to his mouth and nose.

After doing this, Ye Xuan put on his backpack again, and lay in the sand pit with his back to the yellow sand, quietly waiting for the sandstorm to come.

Taking a sip of water in your mouth is not to drink it in an emergency, but to protect your airways and lungs.

The wind in the sandstorm was unusually dry and cold, and at the same time carried a lot of dust and tiny sand. Even through a T-shirt, it can still cause damage to the respiratory tract and lungs. However, when you take a sip of water in your mouth, you can not only absorb sand and dust, but also moisten the lungs with the air you breathe.

Fortunately, Ye Xuan left 100ML of fresh water at that time as a life-saving in case of emergency. Now it seems that it really saved his life.

With water in your mouth, it's easy to say and hard to sit up. You may not feel tired for a few minutes, and you can persist for more than ten minutes or twenty minutes, but after a long time, you will feel a burst of soreness and numbness on the cheeks on both sides of your mouth, which is extremely uncomfortable. It takes a lot of stamina and willpower to keep it up for a few hours.
