The end of the world is somewhat similar to a world war in a sense, everyone is fighting and fighting, and most of the people who have the idea of a corner of peace when the war burns out will not end well. Who died the most during the two world wars? Civilian. High-ranking officials, even those of the army who participated in the war, did not have a high mortality rate.

When the end really comes, after the capable people gather together to form a strong protective circle, even if the population is lost ninety percent, they can stand to the end.

He knows this very well, so he wants to deal with it early.

…………

Zhang Yifei spent a total of four days in the detention center, on the third day Xue Zi and their group of brothers were bailed out, and on the fourth day, Zhang Yifei was also released.

This release speed is beyond his imagination, not to mention the extraordinarily serious criminal cases of more than a dozen murders, just talking about the deflated three who were trampled to death in front of the eyes of everyone in the detention center, this matter will not be easy to solve. Even if you stuff a lot of money, there is no relationship that is hard to the zenith, and you want to release it in four days - it is like a fantasy!

"Could it be that the public security chief did it? But I don't have a relationship with him, and even if I do, even if it is him, I can't do this kind of thing in four days. After returning the mobile wallet, Zhang Yifei muttered in his heart while saving a number in his mobile phone - it was left to him by Xue Zi before leaving, and he was afraid that he would not be able to remember it after a long time, so he saved it easily.

But after saving the number, Li Qing saw a message in the "draft box", and after clicking on it, he saw a special message - "No. 7, Yingcai High School Student Assembly Hall, 2:30 pm, be sure to be there!" ”

"Who left it?" The information in the draft box must have been reserved for the machine, but his mobile phone has been confiscated by the detention center in the past few days, and the only people who may have left information for him are insiders - if I guess correctly, it should have been left by the director himself.

With his authority, it couldn't be easier to look through the detainees' personal belongings.

"But what are you looking for me?" Looking at the date, today is the 5th, and the meeting time is the day after tomorrow, Zhang Yifei is full of doubts in his heart.

The inexplicably kind director did something more than he could do for him, whom he didn't know, or what was very risky, and then wanted to meet him, and the meeting place was chosen in a place that was not suitable for a private meeting at all.

Yingcai High School is an abandoned high school in the suburbs - seven or eight years ago a businessman bought a plot of land in a very suburban area and built a boarding school. According to his ideas, he relied on strict boarding management to isolate himself from the society and achieve a promotion rate and fame. But it backfired, and in the years after the completion of the campus, it was impossible to recruit outstanding students.

Rotten wood is difficult to carve, what kind of things can a group of students who can't get into school and are left behind in the suburbs get together? Within a few years of the school's opening, it was chaotic - smoking, fighting, and even insulting teachers happened from time to time, until later students were stabbed to death in a group fight, and after the exposure was exposed, the admission rate was really poor, the principal ran away, and the school was abandoned.

And because the site was too remote to be developed, the dilapidated school building was long since uninhabited – no one would have chosen it for a private meeting. Even if it is secret, there are places in the city where you can meet and talk, and it is better to choose a sauna in that place, and it can also prevent other people's mobile phone photography.

"To go or not?" When Zhang Yifei walked out of the detention center, there was no one at the door -- as he expected, his own family did not know that he had been released from prison today.

After walking a long way to get a taxi around this remote detention center, Zhang Yifei decided to go to his second uncle's house first.

Anyway, there were still two days to think about that matter, so he decided to discuss the apocalypse with his family first, after all, notifications such as phone calls and text messages always have such an undignified component, and it is better to talk about such a life-threatening matter in person.

"Just came out of it?" After Zhang Yifei got into the car, the taxi driver took the initiative to talk, and seemed to be a talkative person.

"Hmm."

"It's been chaotic outside lately, it's not the whole video on the news, you haven't seen it, the people outside are like crazy these days, and it's even more amazing than in 2012." The driver is in his forties, and he should have mixed with society before, otherwise he would not have no problem with people who have just come out of the detention center, and it is obvious that people of his age are far less receptive to such doomsday rumors than young people, "all full, once in 99 years, once in 12 years, Chinese like to listen to the wind is rain." ”

"What if it's true this time?"

"Even if the end comes, what if a meteorite hits the earth? The earth explodes! It's a big deal, let's die together! ”

The taxi driver talked eloquently, but Zhang Yifei didn't want to answer the conversation, so he just watched the scenery outside the window gradually pass away.

The car was running on the road, and half an hour later it came to the city, and then went around the city for 20 minutes to arrive at Zhang Yifei's second uncle's house. A duplex building.

After pressing the doorbell and the sound of footsteps inside, Zhang Yifei was stunned when he saw his second uncle opening the door.

"What, how did you get out?"

"I have friends to help." When he raised his eyes, he saw that his second uncle Zhang Junjie's eyes were bloodshot, and it was obvious that he hadn't slept well in the past few days. He grew up with this second uncle, although he is not a father and son, but he is closer than most fathers and sons.

"Come in, come in." Holding Zhang Yifei's shoulder, Zhang Junjie let him in, "What's the matter?" I can't send money in the past few days, why do you cause such a big problem, more than a dozen murders? ”

"I didn't do it, and I can't tell." Zhang Yifei rubbed his head as he spoke, as if he wanted to find a trace of a wriggling worm from his scalp - everything after that day was so strange that he couldn't tell himself.

The second uncle saw that Zhang Yifei had an unspeakable appearance, and he didn't ask hard, so he took the initiative to change the topic and talked to him about the doomsday rumors - Zhang Yifei sent a message to remind him of this, but he still said it more clearly in person.

"That rumor should be true...... Zhang Yifei took Zhang Junjie to the study, then turned on the computer to find the video again, and briefly explained the authenticity of the video from the perspective of impact analysis.

"There is no trace of special effects, this is the original shooting ......"

"What exactly is an interstellar dust cloud?" Seeing that Zhang Yifei was so determined, Zhang Junjie asked again.

"Well, it's supposed to be a rock metal particle in the universe...... I'll look it up. Zhang Yifei's astronomical knowledge is limited to what he learned in geography class in junior high and high school, although he will not think that the cosmic dust cloud is a meteorite hitting the earth like the taxi driver, but he can't tell the specifics.

Baidu took a look, and the explanation given by the encyclopedia is about: cosmic dust clouds are dust masks and metal particles gathered together in a certain space in the universe, the cause is unknown, but it is more intuitive to say that it is the fragments left by the explosion of supernova, and some people believe that it was formed in the early days of the universe, and "they" converged into planets.

Zhang Yifei didn't care about how the dust cloud formed, and after skipping it, he studied the influence between the dust cloud and the earth. Soon I saw the key - in fact, there is dust everywhere in the universe, including the current earth absorbs 30 million tons of cosmic dust every year, and more around the sun, which will have a great impact on the climate, but it is not within the scope of extinction species.

The reason lies in two words - sparse.

Ordinary cosmic dust is not called a cosmic dust cloud - only the dust is dense enough to gather into a "cloud" that it can be called such a star.

The cosmic dust cloud is a major "dust storm" in the universe, if you pass by a planet, especially a planet with an oxygen layer, it will have different degrees of impact on the planet according to the density of the dust - if the density is too large, a large amount of dust destroys the oxygen layer, and then spreads the surface, which is likely to directly lead to the destruction of the earth.

Many cosmic dust clouds are very large, Zhang Yifei casually searched for a dust cloud in the constellation of Zhangnan, the length is 800 million light years - and the orbital speed of the solar system is 250 kilometers per second, one light year is 9460500000000 kilometers, and the solar system traveling 250 kilometers per second needs about 37.8 billion seconds to take the earth through such a long distance, and a day is 86,400 seconds, which is 430,000 days, that is, nearly 1,200 years.

Of course, not all cosmic dust clouds are the same, and the dust clouds themselves are not fixed, and the dust clouds in the constellation of Zhangnan are not necessarily positive spheres.

There are areas of high density and areas of low density inside the dust cloud, which is not accurate for 1200 years, but after using the computer to get this number, he knows that the end of the earth will definitely not come and end casually as in the movie.

This will be a more complicated process - it will come quietly, like boiling a frog in warm water, and it may take thousands of years, and there will even be a period of good and bad back and forth in between.

"No wonder the video says that we have entered the edge of the dust cloud, the edge sparse impact is not very large, and it is no wonder that these days are gray ......" Zhang Yifei was more determined after watching this.

And his second uncle Zhang Junjie is not as stubborn as the average older generation, although he has doubts in his heart, he still temporarily accepts the apocalyptic argument and says that he will be prepared.

"Well, you can do some grain business......"

The two had a long talk for a day, calibrating their thoughts.

Zhang Yifei's second uncle started out in the glass business, and occasionally made some other investments, which can be regarded as relatively wealthy. It would have been much better if we had intervened in the "doomsday necessities" business earlier while the chaos had not completely started.

The uncle and nephew talked for a long time, and it was not until it was dark that Zhang Yifei left first, and when he returned home, although he was thinking about his future plans - but more thoughts were put on the meeting the day after tomorrow.

"What the hell is that?"
