Doomsday Bunker Upgrade Chapter 1: Are you ready when the meteorite strikes?

A day that was originally Christmas, after experiencing many disasters and disasters this year, people are eagerly hoping that this year can pass earlier and the disasters can subside.

　　 After all, this year is a year full of pain for all mankind.

　　 plague, famine, war, death, the Four Horsemen of the Apocalypse recorded in the Bible almost ravaged the world once, and human beings are obviously so vulnerable to the disasters brought about by nature.

But people have not given up hope. Even in the face of disasters, we are still fighting hard, fighting against these disasters, showing the most precious golden spirit of mankind - full of hope and never bowing to disasters.

　　 However, it is as if God made a big joke with humans. On this day, a huge meteorite with a diameter of more than ten kilometers was discovered by astronomers, and the astronomers confirmed the orbit of this huge meteorite after calculations. It will intersect the orbit of the blue star and will hit the blue star within a few months.

After learning the news, governments of various countries immediately blocked the news. In order to avoid social panic, almost all astronomers were banned.

But this kind of news is unstoppable.

After all, meteorites hang in the sky. As meteorites get closer and closer to the blue star, astronomy enthusiasts around the world can see the brighter and bigger comets in the night sky as long as they set up telescopes.

Moreover, the space operations and various countermeasures that the governments of various countries immediately launched, in this era of such a developed Internet, it is difficult not to be caught.

　　 These clues naturally spread to the Internet, arousing eager discussion at the same time, some foresighted people began to hoard materials after smelling the clues.

　　 There have been too many disasters this year, and many people already have experience.

Food, medicine, protective equipment, communication equipment... these emergency supplies were sold out immediately.

　　 Fortunately, there are many disasters this year. Companies that produce these emergency supplies have increased their production of these disaster-response necessities, especially emergency food that can be stored for 20 or even 40 years. The most in short supply at this time.

Although this year, emergency food has been one of the most popular disaster response materials after protective equipment.

It's just that, in Chen Xin's opinion, it's more important to dig a shelter for yourself than to snap up these supplies.

　　Chen Xin is an internet writer. He usually lives on codewords on various websites. As a writer, the most important thing is his brain and logical thinking ability. After all, the so-called novel is essentially an attractive People's logic is fluent in the brain.

And this has undoubtedly caused Chen Xin to think more complicated than others in the face of this possible disaster.

　　The meteorite hits the blue star, how should humans avoid disaster?

　　 This question came to Chen Xin's mind for the first time.

　　 Fortunately, as an Internet writer, Chen Xin usually has a lot of brain holes, and he also has the habit of recording these brain holes and trying to think and perfect, and the situation of the meteorite hitting the blue star happened to be thought by Chen Xin Within the range of the brain hole passed.

　　While hoarding supplies, while searching for information that may be found on the Internet, Chen Xin has not forgotten to find out the brain holes he had thought from the folder where he recorded his brain holes.

　　The giant meteorite hits the blue star, and the first thing it brings is a violent impact.

　　 Judging by the current size of this meteorite, even if countries have space interception plans, the probability of success is not high. The most likely thing is that the meteorite will be broken into several smaller pieces due to human interception actions, or Past the blue star, or hit the blue star.

However, this does not mean that the degree of disaster will be reduced, and don't think that small meteorites are not so dangerous, because this small size is relative to the body of the meteorite with a diameter of more than ten kilometers.

Even if it is broken into pieces of meteorites several kilometers in size, hitting the blue star can still bring devastating disasters.

A meteorite with a diameter of more than five kilometers or more hits the Blue Star, and the impact site has a radius of at least 1,000 kilometers.

　　The impact meteorite will lift the material near the impact site directly into space, and the thermal energy generated by the meteorite friction with the atmosphere and the energy released by the impact will form a block that is at least ten kilometers high and the temperature exceeds several A fiery wall of fire of thousands of degrees Celsius swept everything within a radius of at least 1,500 kilometers.

　　 Within this range, even if you can hide in an underground bunker, there is a high probability that you will be familiar with the high temperature in the bunker like a stuffed kiln chicken in Meizhou, Guangdong, even if you dug the bunker deep enough, then An earthquake of at least magnitude 11 or higher is enough to bury you alive.

If you are lucky, perhaps tens of millions of years later, if humans survive, you will be able to unearth your fossils.

If you are interested in leaving some traces for human beings, you can give your middle finger, and the human beings in future generations will definitely be moved by your optimistic spirit.

　　 The shock wave caused by a meteorite impact will spread back and forth several times around the world at a speed of several times the speed of sound, so no matter where you are in any corner of the blue star, you can hear the violent sound produced by the meteorite impact. .

If you are in the opposite hemisphere when the meteorite hits, there is no danger for now, and the sound of the shock wave is enough to remind you to take cover.

　　 But all this is just the beginning, the disaster has just begun.

　　 In the next few days, a fire storm composed of haze and gravel will cover the entire Blue Star, causing the global temperature to rise from two levels to the equator to 70-200 degrees, turning the entire surface of the Blue Star into one Huge oven.

　　 The entire earth's surface will become unsuitable for human survival. All plants will be roasted and burned by this high temperature. The toxic and harmful gases produced by global fires will spread throughout the atmosphere~IndoMTL.com~ Most creatures on the surface of the dead.

And all of this is still just the prelude and prelude to the disaster. Everything can only be said to be an appetizer before the big meal.

Due to the increase in atmospheric temperature, the sea level will also rise rapidly. In addition, the kinetic energy released by the meteorite impact will produce a tsunami with a height of thousands of meters that will impact almost all coastal cities.

　　The dust cloud raised by the impact and the haze formed by the toxic gas produced by the global fire will block the sunlight, cover the blue star for dozens or even hundreds of years, and plunge the blue star into a long dark night.

The material thrown into space by the meteorite impact and the smaller meteorite fragments entrained by the meteorite itself will continue to collide with the Blue Star.

In the hemisphere where the meteorite hits, it's like carpet bombing, and the constant impact of meteorites will leave few people in the entire hemisphere surviving.

Even if you can hide in an underground bunker, it is impossible to survive the meteorite bombardment that ranges from a few meters to a few hundred meters almost every day.

　　 As for the hemisphere where the impact location is opposite, luck will be slightly better, but there will also be a meteorite falling randomly. It can almost be said that there is a certain chance that the meteorite will smash several tall buildings when you go out.

But that's not the end, as the world is covered in a thick haze of dust and toxic gases that will cool rapidly over the next few months.

If the high latitude cities were not destroyed by the impact, the temperature would drop to minus 70 degrees, and the equatorial regions would be slightly better, about minus 20 to 30 degrees.

　　 Because this long night without seeing the sky will last for dozens or even hundreds of years, the extremely cold weather will also last for a whole century. In this long and extremely cold night, the setting of the ice age will become a reality. .
