"Shhh The temperature around it plummeted, and although it didn't reach the level of the night in the polar Pluto desert, it should be below freezing.

"Did you bring any clothes?" Yu Hao's physical fitness has improved a lot because of the first strengthening, and this cold is just a little chill for him, and there is almost no problem when he takes out a sweatshirt and puts it on his body.

"Brought it, I almost froze to death in the desert last time, can you not have a memory?" Luo Xiao smiled, he didn't have such a good physical fitness as Yu Hao, in addition to the sweater, he also put on a thick cotton coat to suppress the cold.

It seems that with the experience of military training, many students also prepared some warm clothes, as for those who did not prepare anything, it can only be said that they do not deserve to live here.

There were snowflakes in the sky, and there were collapsed buildings all around, and under their feet was a thick layer of ice, and at least twenty or thirty meters of those buildings were buried under this solid ice.

"Yu Hao, look, there's someone inside!" Luo Xiao lay on the ice, only to see that there were vaguely visible figures in the depths of the ice, and they actually became living fossils in this ice and snow.

"It seems that this place has experienced drastic climate change," Yu Hao inferred, "Have you seen 'The Day After Tomorrow'?" The sea poured into the city, freezing the entire continent, and it was a sight to behold. ”

"Let's look for clues first, the principal didn't tell us the specific situation of this world, it should be that he wants us to find the answer to this world by ourselves." Luo Xiao suggested, "Maybe it's better for us to act together as a class at first. ”

"Well, but you have to be careful, there is a mission that says that we want to kill five creatures above H+ that have been affected by nuclear radiation, and Mr. Bai said that H+ should be a creature with about the same strength as us."

"Everyone, let's discuss it first, since everyone is in the same class, then we must cooperate with each other, otherwise it will become a mess like military training." At this moment, a young man in the class with colorful hair shouted loudly.

"Let's go, let's go and see first." 30 days of survival mission, they are not in a hurry at this time.

Obviously, many people are in favor of cooperation, after all, the power of one person is too small, and the power of many people is great, and everyone brainstorms together, maybe they can survive this entrance exam? Soon, the top of a half-collapsed building was filled with students in the class.

"Students, now we don't know anything about this place, the most important thing is to have a certain understanding of it first, otherwise we don't even know where we are, we don't know what situation we are, how can we survive?" I have to say that although this young man seems to be in a flow of anger, his analysis is very reasonable.

"I suggest we look for clues in the surrounding buildings that are still accessible."

"yes, that's what I mean."

"Okay, in that case, let's start with two or three people as a group, look for any valuable clues nearby, and we'll gather here in an hour!" The young man naturally took on the role of assigning tasks, but everyone seemed to acquiesce, and they scattered in small groups of threes and twos.

"Noticed?" Yu Hao said.

"Well, this guy doesn't seem reliable, but he has a little brain, and he gathers everyone's strength when everyone is confused, and he himself takes on the role of team leader as a matter of course, and can quietly grasp the control of the entire class." Luo Xiao analyzed his purpose in just a few words.

"But it doesn't matter, we don't have a clear purpose yet, let's listen to his arrangement first, at least so far, he is still a qualified leader." For Yu Hao, in fact, coordinating so many people is a big trouble, and since someone is willing to take on this role, he is naturally welcome.

"Well, that's it for now."

"Bang dang!" The two of them wasted a lot of effort and finally smashed the glass of a building, even if Yu Hao almost had more than four times the strength of ordinary people, he actually smashed it dozens of times, and even doubted whether the glass was domestic.

This should be an ordinary residential building, and the decoration inside does not seem to be too far from their real world, could it be that this world is what the future of the earth will look like?

"Hey, Yu Hao, come and see!" Luo Xiao's voice came from the next room.

Yu Hao hurriedly walked over, this seemed to be a study.

"Look, there's some magazines and paper newspapers here!" Luo Xiao was holding a newspaper and reading it, the words on it looked strange, but I don't know why, it read as smoothly as the country's native language, maybe this should be the principal's masterpiece.

"You see, the year in the newspaper is 4 years from the New Era, and according to the degree of change in this paper, it should have been more than ten years." Yu Hao judged, and according to the style of the building and the facilities inside, it should be about the same level of civilization as the earth.

He continued to read along with the impurities, and finally had a general understanding of this so-called "lost world".

The planet's name is Sal, and it is the only known civilization in this star system. There are a total of 98 regions of a similar national nature on the planet Saar, and there has been a perennial war over the competition for resources. Finally, one year, a nuclear war broke out that swept the entire planet, and almost 90% of the nuclear weapons of the planet Thrall were used, and almost the entire planet was shrouded in a war.

The series of catastrophic consequences caused by nuclear war erupted in just a few years, the Saar planetary ecosphere collapsed, glaciers melted massively, and tsunamis swept countless coastal cities. And the movement of the blocks caused by the nuclear explosion caused the tearing of continents, earthquakes, volcanic eruptions, and in just a few years, the whole world seemed to usher in the end of the world.

The planet Sal originally had a population of 5.4 billion, but in just five years and ten years, more than half of the population has been lost, and now there are less than two billion left. Under the weight of the imminent extinction of humanity, the 98 nations finally gave up the war and united into a federal government to save the following humanity, and that year became known as the first year of the new era.

However, the global environment continued to deteriorate, and humans had to migrate on a large scale, and the city escaped the first few years of the disaster because of its high terrain and relatively solid tectonic plates, but as the glaciers continued to melt, it was finally submerged.

"It seems that it has now reached the stage of nuclear winter!" Yu Hao said.

The massive amounts of energy and soot produced by a nuclear explosion and the resulting geological changes can raise global temperatures in a short period of time, causing glaciers to melt, sea levels to rise, and even to inundate cities. But after a period of time, due to a long-term lack of sunlight, the temperature drops rapidly, entering a "nuclear winter" similar to an ice age.

"How terrifying is a global nuclear war?" Living in relative peace, they could hardly imagine that kind of scene.

According to the information in this newspaper, the federal government is urging the surviving residents to immediately go to the government-established underground survival base, which is the latest newspaper and miscellaneous material they can find.

"Looks like we're going to have to find a way to find those underground survival bases as soon as possible!" Although Yu Hao is not afraid of the cold, but without enough food and water, it is impossible for them to survive for 30 days, although some food can be found in these buildings, but what is more than ten years ago, who dares to eat it?

"Ahh At this moment, a shrill cry resounded throughout the frozen city......
