It was completely dark.

Without the sun, the surface temperature is rapidly lost.

Everyone had just experienced the sauna for a while, and soon they were shivering with cold.

A cold wind blew, and everyone involuntarily bent down and hugged their bodies with both hands.

After a while, someone was already fighting with their teeth from the cold.

"This place, no wonder there is no grass, it's hot for a while and cold for a while!"

"Nonsense! There are many forbidden areas for life on Earth, and this is one of them, and how many people enter the desert and never get out again, it's no joke. ”

"How do I feel, it's the same here as the prairie? It's hot to death during the day, and cold to death at night. ”

"If this is the grassland, then I'll be thankful, at least there's water to drink in the grassland, and we can catch some prey. But there's nothing but sand. ”

"Don't talk nonsense!"

Lin Hui shouted in front: "Hurry up, we must find a water source as soon as possible." Now shut up for me, take all your strength out and run, and follow me! ”

He turned his head, and everyone honestly shut up.

Try to spread your legs and follow closely behind Lin Hui.

At this time, Lin Hui no longer had a smile on his face, and his face was full of seriousness.

He knew very well that the desert was much harsher than the natural environment of the meadow jungle.

During the day, it is more than 40 degrees, and at night it may reach more than 10 degrees below zero.

They didn't have any cotton clothes, and they didn't have any calories.

If you don't find a water source as soon as possible and get a good rest.

Tomorrow morning, someone has to hang up.

He brought people to train, not watched his men die.

Moreover, just the little thing in his bag can't save everyone's lives.

So you have to find a water source as soon as possible.

Along the way, although he kept running, his eyes kept searching around.

The knowledge of survival in the desert in my mind is played over and over again.

[Ding, congratulations to the host, desert adaptability +1!] 】

Lin Hui gritted his teeth: "Don't +1, hurry up and help me find some water!" ”

He can hold on, but the soldiers under him can't last long.

Half an hour later, everyone followed Lin Hui over a sand dune.

Standing on the top of the sand dune, Lin Hui's eyes instantly lit up.

Not far ahead, something resembling a building appeared.

Lin Hui was suddenly overjoyed: "Quick, over there, let's go!" ”

Everyone's heads were a little confused.

only heard Lin Hui say to go, so he followed him without hesitation.

Where the desert seems close, it is often far away.

It took forty minutes to reach this ruined wall.

Everyone was extremely tired at this time, and one by one they either fell straight upright, or knelt down with a thud.

Most of them are exhausted by this point.

His face was purple from the cold, and his lips were dry and cracked.

"Does anyone else have the strength?"

Lin Hui roared: "Follow me, I need manpower!" ”

Jiang Liang stood up with difficulty: "I'll come!" ”

Wang Yong and the others all stood up.

Lin Hui shouted at Zhou Zhongyi: "Others, find a place to rest immediately, quickly!" Jiang Liang, Wang Yong, you guys come with me! ”

Zhou Zhongyi followed and shouted: "Don't lie here, hurry up, come here, everyone help each other, go inside!" ”

Those who fell down got up with difficulty, and those who still had a little strength helped those who had no strength at all.

Some even dragged one by three or four people and ran towards the ruins.

Jiang Liang and Wang Yong followed behind Lin Hui and spun around in the ruins.

After walking for a while, Lin Hui suddenly stopped.

His gaze fell on a ruin.

At this moment, his eyes lit up: "Come here!" ”

Immediately, he rushed over first.

Several other people took a look at it and hurriedly followed.

Lin Hui walked into the ruins, surrounded by rammed loess.

It looks like it was once a building.

Everyone looked around, and Chen Erhu asked curiously, "Brigade Commander, what kind of place is this?" ”

Lin Hui began to look on the ground and said: "The desert has not always been a desert, in the long river of history, the desert we are in now may have been a rich land hundreds of years ago. ”

"Have you ever heard of the Ancient Kingdom of the Western Regions? At that time, the water and grass were abundant here, and one splendid civilization after another shone here. ”

"Although they are buried in the sand forever, they can still find water where they once lived."

Several people suddenly came to their senses, and Jiang Liang asked, "Brigade commander, are you saying that this was once a country?" ”

"Who knows?" Lin Hui shrugged: "Anyway, there have been people living here, as long as there are people living here, it means that there is a water source in this area, otherwise what are you doing here." ”

"Come here, here it is."

Lin Hui pointed to a recessed place.

It looks very different here and around.

Because there are actually some plants growing in this area.

Although it looked like it had withered, it was the first time they had seen a plant in a whole day in the desert.

Lin Hui pulled out a few plants on the ground and threw them to Wang Yong: "There is juice at the root of the plant, take out the bottle, you are responsible for collecting it, and squeeze it hard for me." ”

Wang Yong suddenly became excited.

Although I don't know if it's true or not.

But seeing Lin Hui so serious, there must be a drama in most of the time.

"You guys, get a shovel and dig it."

"Yes."

The rest of the men immediately came over with shovels.

Find the place Lin Hui pointed to and start digging hard.

One, two, three.

Soon, they dug a hole in the depression.

The pit was dug deeper and deeper, and soon a half-man-high pit was dug out.

Chen Erhu had a bitter face: "Brigade commander, what are we going to dig?" ”

Lin Hui: "Nonsense, of course it's digging water." ”

Jiang Liang cried with a sad face: "Digging water? No kidding, can you still dig water in this kind of place? ”

Lin Hui was cold: "Then why do you think these plants suddenly grow here." ”

"Since this place has been inhabited before, it means that there is a high probability that there is groundwater passing by."

"Don't think that desert plants don't need water because they are drought-resistant, these plants need water to grow so tall."

"Dig now!"

The crowd was suspicious.

This place looks like there is water somewhere.

But seeing that Lin Hui was so serious, they could only continue to dig.

"Wet, wet, the sand is wet!" Chen Erhu suddenly shouted in surprise.

Sure enough, the sand was indeed wet under the shovel he had just dug in.

"Dig fast, dig fast!"

Everyone was also excited, and they used their strength to dig up desperately.

After a few moments, the sand was completely wet under their feet.

And there's a little bit of water slowly seeping out.

"There's really water, there's really water!"

"I'll go there, this kind of hellish place can dig up water!"

Chen Erhu squatted down excitedly, just about to drink water.

"Don't drink!"

Lin Hui's low roar startled everyone.

He squatted on the ground and snorted coldly: "This water is not filtered, if you drink it now, you will not die or be crippled." Keep digging! ”

Chen Erhu's scalp suddenly tingled.

Looking at the water coming up from the ground, he swallowed his dry throat fiercely and immediately dug again.

After a while, more and more water came out.

Already in the midst of them, a small puddle was formed.

And, it's still popping up.

"Take out the gauze from your backpack, cover it on water, and do a preliminary filter, faster!"

"Oooo

Everyone quickly reacted.

Put down your backpack and rummage through it.

Soon found a gauze.

Before, I thought it was useless to occupy space, but now it seems.

The use of everything in the backpack, Lin Hui had already thought about it for them.

Lin Hui jumped into the pit, took a piece of gauze from Jiang Liang's hand, and slowly rolled it towards the water.

Soon, water came out little by little through the gauze.

The sediment was also pressed under the gauze and slowly sank.

Lin Hui brought another piece of gauze and covered it.

When the sediment sinks again, it is covered with another layer.

Although the water is still very muddy, it is much clearer than before.

The underground water source in the desert cannot be drunk directly, and there are too many impurities and bacteria in it, which is harmful to the body.

However, when you are extremely dehydrated and can't find a source of water, it's okay to drink less.

"Quick, store the water first!"

"Yes!"

The crowd picked up the bottles and scooped up the water little by little.

After the bottle was filled, Lin Hui had already built a simple water filtration device next to it.

There are three layers of gauze on the shelf, and the bottom layer of gauze resembles a funnel shape.

Inside is a little sand and charcoal ash as a filter element.

Directly below is a bottle.

Lin Hui took out a bottle of water and poured it slowly.

The water passes through the first layer, leaving a little bit of sand behind.

When it dripped into the second layer, the water stain was noticeably clearer, leaving a little more sand.

Finally, it is dropped into the third layer, and after the adsorption of charcoal ash, drops of relatively clear water fall into the bottle.

The other soldiers were staring at the water in the bottle, their throats smoking.

At this moment, no elixir can compare to this bottle of water.

For them, it's too precious.

"Do as I do, hurry, hurry!"

He handed a bottle of water to Jiang Liang: "Go and distribute it to everyone to drink, remember to replenish it in small sips." After recovering, find some more people to come over, and collect everyone's bottles. ”

Jiang Liang nodded vigorously, took the bottle, and took two sips.

Feeling the liquid rolling down his throat, he felt a lot more comfortable.

"I feel like I'm alive again!"

He excitedly climbed out of the pit and ran towards the crowd.

After a while, more than thirty soldiers who had just finished replenishing their water ran over.

One by one, when I saw the water seeping out of the bunker, it was like seeing gold, and my eyes lit up.

However, the bunker was too small to accommodate so many people at the same time.

They can only prop up the filter outside.

The people inside handed them the preliminarily filtered water.

They do one more filter outside.

Lin Hui saw that everyone had gradually become proficient, and climbed out of the pit with a smile: "The water here can save our lives for the time being." ”

"However, we still have to make other supplies, so we may not be so lucky next time."

"Hydrate everyone first, and then mobilize people to come."

"Yes."

Lin Hui moved his body with a smile.

This training is so important for everyone.

If you can survive in the cruel desert.

Then they can live anywhere.

The soldiers of the Flying Tiger Brigade are as tenacious as the plants in the desert.

No matter how harsh the natural environment is, they can survive with incredible tenacity.

Only by surviving can they continue to fight, truly defeat the enemy, and better defend the country!
