The sandstorm raged for several hours, Yu Hao only felt that the wind and sand on his body had accumulated layer after layer, even if he covered his nose with his clothes, he was still a little breathless, and the high degree of hypoxia and stuffiness made him almost faint, but he knew that once he passed out, it would be difficult to wake up again.

The sound of the wind gradually became quieter, and Yu Hao climbed out of a sand dune, he looked extremely embarrassed at the moment, gulping in on the air, but it had reached the hottest time of almost noon, and he felt that every breath of air was extremely hot and dry.

"I'm afraid the temperature is close to 50 degrees, and if you continue like this, you will soon be dehydrated." Yu Hao was covered in sweat, and even his skin was a little stinging under the sun, and there was a faint feeling of dizziness, and he knew very well that he already had some signs of dehydration.

"You must quickly find a shady place, preferably a water source, otherwise even if you survive today, you won't survive tomorrow!" Living without drinking water for three days is just under normal temperature and humidity, and in this extremely dry and hot place, I am afraid that it will not be able to hold up for two days.

The surrounding terrain has been completely changed by the sandstorm, and there is no trace of any classmates around, and I don't know whether they ran to other places or were buried under the sand.

Despite the unbearable heat, he wore the coat on his body, the only way to stop his body from losing water right now.

"There's a dry riverbed!" Yu Hao stood on a sand dune, looking from afar, there was a winding valley about a dozen kilometers away, according to his geographical knowledge, there was no water on the surface of the dry riverbed, but it should be possible to dig water at a depth of about one or two meters underground.

Although this is only a possibility, but now Yu Hao has no other choice but that place, even if he does not find a water source, relying on the shade of the valley, he can at least avoid direct exposure to the sun, enough to support the water in his body until the next day.

More than ten kilometers of road, he walked for several hours, the sun on the horizon gradually set, the rapid drop in temperature made his somewhat prostrated body finally regain some strength, but he knew very well that what followed was a very low night, a temperature difference of 80 degrees Celsius, the temperature here at night can definitely reach minus 30 degrees, relying on this thin clothes, one night is enough to freeze him to death.

"The matter of finding water can be put on tomorrow, and tonight's low temperature must be overcome first!" Yu Hao looked around, there was no trace of any plants nearby, even if he drilled wood to make fire, he had to have wood, right? Not to mention wood, there is nothing to be found here except yellow sand and stones.

"This damn school doesn't leave anyone alive at all!" Yu Hao kicked on a stone and directly kicked it to pieces.

"Huh? So crispy? Yu Hao squatted down, "No, this is not a stone, this seems to be the feces of some kind of animal!" ”

He was immediately happy, although there was no wood and hay, but the dried manure of herbivores could also be burned, and after the baptism of high temperature, it was not easy for him to find wet manure.

Yu Hao immediately searched around, and under the Gobi in the valley, he found a small cave, without any smell, there should not be any creatures living here, the cave is several meters deep, and there is even a bend, which can completely help him resist the cold wind.

"Luckily, if we can find some water, we can survive five days in this place!" Yu Hao found a lot of similar dried feces, and at this time he had to thank some popular science programs that he had often watched before, otherwise he would miss these life-saving things in front of him.

The sky gradually darkened, and the temperature of the desert began to drop suddenly, and Yu Hao felt that his body was already a little stiff and shivering at six o'clock. Luckily, he found a few pieces of wood in the sand while he was looking for dry dung, and he should have no problem surviving this evening.

He collected some rocks and piled them at the mouth of the cave, which would more or less help him to hold back a little wind.

"Smack!"

"Smack!"

He struck the two stones in his hand hard, but the extremely simple stone striking to make a fire on TV was not so easy in practice, that little spark might be able to ignite the hay, but it didn't seem to be so easy to ignite the combustible parts of the dung, and soon his hands were grinding one bubble after another.

"Why can't you order it!" Yu Hao sniffed, the temperature had become very low, and his legs already had a slight lack of blood circulation.

"Smack!" After nearly an hour of hard work, a little spark finally landed on a piece of dung that had lost its moisture, and with a foul smell, the dung began to burn.

"Why does it stink so much!" Despite the evil spirit, Yu Hao had to endure it, and he put a few pieces of wood in the proposed stove made of stones, and finally felt a trace of warmth and hugged himself into his arms.

......

The hardest night passed, Yu Hao rubbed his arms that were a little numb, the fire had been extinguished, there were still some faint sparks left, he covered some dry dung and spread a layer of sand, so that he didn't have to fight so hard at night.

"Well, yes, it's a big bowl!" Yu Hao looked at a small water intake device outside, after a night of condensation and backflow, there were already hundreds of milliliters of water on the sunken stones, although there was some sand underneath, but the surface was extremely pure.

"If you have some wild vegetables or something, you can cook a pot of hot soup at night." Yu Hao drank very sparingly, and collected the remaining water into the independent space of the ring turned into the school emblem, which was enough for him to drink for two days.

"Hurry up and look for some supplies before the temperature comes up!" According to his judgment, he had at least three or four hours to move, and then the scorching sun was about to usher in again, and before that he had to return to this place.

"I don't know what happened to the others." He hadn't seen any of his classmates since the sandstorm, and a day had passed, and there must have been a lot of people who had already encountered an accident, if they didn't have any survival skills in the wild, even if they barely survived the scorching sun, they would definitely not survive the night.

......

After drinking a little water, Yu Hao returned to the small cave again, and now he finally had a little energy to think about the sentence he had cared about before.

"Starve the faint-hearted, support the bold, what does this sentence really mean? Is there any other way to earn credits than to complete the mission of survival? ”
