"Mr. Chen, no, there is a low-pressure cold air mass, which is moving towards central Siberia, which happens to be our position!"

When Chen Xu heard this, he immediately ran to the monitoring equipment and took a look.

The audience can also see that on the green satellite map of Siberia, there is a white air mass slowly attacking from the north to the south.

"At this rate, it is estimated that it will arrive before tonight, and there is a possibility of rain, or sleet, and for the night in Siberia, once wet by rain, the loss of body temperature caused by the evaporation of liquids, and the low temperature environment, will quickly freeze a person. ”

"Hopefully they can spot the weather change from the clouds and plan for the camp, a good campsite can successfully avoid this sleet, otherwise, if something goes wrong, someone will be out tonight. ”

"And the most important thing is that in this bad weather, helicopters can't fly, it's too dangerous, everything can only rely on our missile launcher, but we are in the Siberian mountains and forests more than 100 kilometers away from the participants, even if we rush to the fastest speed, it will take at least an hour!"

The audience naturally heard the worry in Xu Ye's mouth, because, in the extremely harsh environment of Siberia, if an accident really happens, an hour is enough to take a person's life.

However, the four participants did not appear to notice the anomaly of the clouds.

Their main attention was still on the road, after all, no one wanted to live in the snowy mountains tonight.

Through the close-up shooting of the close-up drone, it can be seen that the faces of several people are showing a state of exhaustion, and their lips are also a little dry, I don't know if it is caused by thirst or the cold weather is too dry.

"As soon as I saw their lips dry, I thought of the picture of Xu Ye last time in the Sahara thirsty and dead dog, 23333!"

"In a place like Siberia, there should be no shortage of water, there is snow everywhere!"

"No, how do I remember that Xu Ye once said during the live broadcast in the Alps, it seems that you can't directly eat snow to quench your thirst. ”

Seeing that someone raised this question, Chen Xu also nodded and said:

"Some viewers are right, in the wild, eating snow directly does not quench thirst, everyone knows that snow is actually very soft, just like marshmallows, the water concentration is very low, so, a ball of snow in the hand, its air content is generally more than 90%. ”

"When you take snow in your mouth and melt, it will first absorb the moisture from your oral mucosa, causing you to be thirstier in the same way that it is like a marshmallow, and eating a lot of snow will quickly lower the core temperature of your body just like eating a cold drink. ”

"So, on the Matterhorn, I once taught everyone to try to melt the snow before drinking, which is much better than eating the snow directly. ”

Fortunately, several of them are professionals with rich outdoor experience, and there is no snow-eating behavior in the audience's barrage.

About another hour later, the 100-hour countdown in the lower left corner had become 96:44:21, and Lin Xiaoman became the first participant among the four to reach the foot of the mountain.

It can be seen that in front of the permafrost plain, there is a yellow landform, which should be the Siberian plain, but it is not a flat river, next to the grassland, there are several snow-capped mountains, I don't know if it will form an obstruction.

At this time, Wang Chunliang saw the clouds in the sky, and explained a few words in front of the camera, it is a fish scale spot, which belongs to the translucent Altocumulus cloud, which proves that there must be cold air to attack and produce rain.

Chen Xu nodded, although Wang Chunliang had no professional military training and his physical strength was not outstanding, his eight years of experience in field exploration made him very sensitive to environmental changes.

"I've got to hurry up, I've got to build shelter before the rain rains down!"

After speaking, Wang Chunliang increased the speed of his journey.

After more than half an hour, all four participants reached the foot of the mountain, but because of the different slopes of the mountains and rivers and the different roads, the distance between the four was widened.

Lin Xiaoman had already walked to the shrub and grassland area, she had already put on a military coat, and somehow, she felt that the temperature at the foot of the mountain was even lower than on the top of the mountain.

In fact, this was due to the cooling of the cold air brought by the low pressure mass, but she did not notice a change in the weather yet.

Around her feet, there was basically yellow-green dead grass and shrubs about the height of her calves.

It can be seen that Lin Xiaoman walking on the plains is more careful than on the snowy mountains.

Because, plains, plants, means that there may be carnivores or large animals.

But Chen Xu knows more, Siberia is the world of plain wolves, which is one of the most densely populated areas of wolves in the world, with more than 60,000 horses, and every year, more than 5,000 humans and livestock are killed in Siberia because of the outbreak of wolf plagues, resulting in economic losses of more than 60 million US dollars.

Therefore, Russia is also one of the few countries in the world where you can hunt wolves with documents, especially when wolf plagues break out every year, hunting wolves has even become a popular tourist project.

But now is not the time to worry about the wolves, as most of them operate at night, and the biggest challenge for the four participants now is how to deal with the coming cold and sleet!

He saw the air mass on the monitoring map, which had reached central Siberia.

At this time, the sun had long since disappeared, and the sky became gloomy, except for Wang Chunliang, the remaining three participants also noticed that something was wrong with the weather.

"It's over! It's going to rain!"

"No, I've got to set up a campsite quickly!"

……

They said a word, and then began to anxiously search the plains for a camp to rely on.

But it's a pity that there is not even a decent tree within a radius of dozens of miles, not to mention caves or boulders that can keep out the rain.

Chen Xu frowned and analyzed while watching the movements of the four people: "The sleet is coming soon, and among the several people, except for Wang Chunliang, who has already started to build a campsite, the remaining three are still on the way to find shelter. ”

"If I were faced with such a situation, I would choose to make a fire as soon as possible, in a place like Siberia, the temperature is too low, it is already difficult to make a fire, and in case the sleet falls for a while, wetting the branches and dead trees, it will be even more difficult!"

"If there is no fire, there is no way to keep warm, and the cold will dull the brain and body, and it will also cause colds and fevers, and if this continues, the disadvantages will snowball, becoming more and more!"
