On December 25, 3022 A.D., people were celebrating Christmas with joy when a catastrophe was coming upon them.

An extraterrestrial meteorite broke into the Earth's atmosphere, and people and scientists thought it was just an ordinary meteorite, and people made wishes to it, but who knew that this meteorite was the beginning of a nightmare. No one knows that the meteorite carries a cosmic virus that can alter the genetic chain of humans and animals, but if this change is interrupted, or if the infected person cannot bear the pain of the change, both humans and other creatures will mutate. If you can withstand it, you will have unexpected abilities. However, the virus is extremely contagious.

The meteorite fell in the Atlantic Ocean, and the virus inside the meteorite spread to freshwater at an extremely fast rate. Soon all the water sources on the earth will be polluted, no matter whether humans or other creatures drink contaminated water, even if the water is boiled, they will be infected, and this virus cannot be killed!

Slowly. Scientists have found through research that humans who are infected by this virus and have not successfully evolved will become zombies similar to those in science fiction movies in the United States, with no sense, sight and touch, only hearing. And the humans who have successfully evolved, no matter what abilities you have evolved, are collectively called new humans by scientists. Animals that have successfully evolved are called corpse beasts, and those that have successfully evolved are called demonic beasts. Whether it is for successful evolution or successful evolution, there are corresponding levels, SSSS level to E level, E level is the lowest, and SSSS is the highest.

In 3052 AD, 30 years after the end of the world, mankind established four major alliances, the European Union, led by the United States; the Eastern European Union, led by Germany; the Central Asian Alliance, led by Huaxia; African Union, led by South Africa.

On December 58, 3052, in a research institute in Longcheng Base City, Huaxia.

Dean Zhang, the dean of the research institute, said to a middle-aged man standing beside him: "Team Jiang, are you sure you want to send the base back to the past, everything you have now is brought to you by the base, and it is also your current dependence, now many bigwigs in the central government regard you as a thorn in the flesh, if they know that you send the base back to the past, those bigwigs are afraid that they will do something to you!" ”

The middle-aged man said: "Zhang Yuan, you can rest assured of this, if they want to do something to me, even if I die, I will bite a piece of meat from them, not to mention that I will soon break through the SSSS level and enter the SSSSS, which is what people often call the god level, do you think I will be afraid of them!" After listening to the middle-aged man's words, Dean Zhang's eyes widened at the boss, and he looked incredulous.

Dean Zhang was surprised: "What, you're about to reach the god level." No wonder you send the base back in time, to the past you. The middle-aged man said: "I am not doing this for myself, but I want more people to live through the base and strive to win this battle as soon as possible, there are too many people who have died over the years." You see, how many people are left in the four major human alliances now, adding up to just over 1 billion. Therefore, I must send the base back to the past, so that my past self can build the base city with the base as the background faster. Alright, Zhang Yuan, let's hurry up and send the base back to the past! ”

After the middle-aged man finished speaking, he put the base he said into a box that looked like a courier package, took out a letter from his jacket pocket, and put it in the box as well. He put the box on a disc-like device and said to Dean Zhang, "Zhang Yuan, let's start." The time is set for December 22, 2022, so I have a few more days to prepare. ”

After the middle-aged man finished speaking, Dean Zhang activated the disc, only to see a light hit the box. When the beam disappeared, the box disappeared with the beam, and it felt like it had never existed again.

The middle-aged man thought to himself: "In the past, I could only help you so much, and the rest can only rely on yourself." ”
