One day on the earth, the fourth world war broke out, due to the scarcity of earth resources and the high development of nuclear weapons at that time, human beings in order to compete for resources, and washed away reason, nuclear weapons were fully used in war, but no one expected that the final result would evolve into a situation that human beings never imagined: nuclear war lasted less than a month, the human population was sharply reduced by two-thirds, earthquakes, tsunamis broke out non-stop, various animals and plants mutated, and nature began the strongest revenge in history.

Under the influence of nuclear radiation, animals and plants have undergone strong mutations, plants have begun to have a preliminary consciousness, they are not only rooted in the ground, to absorb the nutrients of the land, they will also use branches and leaves to attack other species, to obtain the required nutrients, some plant branches are harder than steel, branches can easily penetrate a few centimeters thick iron plates, and shatter bulletproof glass, if humans or beasts are accidentally stabbed and do not flee immediately, they will soon be sucked dry blood and die, some plants will also produce highly poisonous, by spreading smell and liquid to kill enemies and preyPlants with powerful poisons can even directly corrode opponents into blood, and animals have become more violent and attacking, mutated beasts have sharper claws and more changeable species, and even beasts that were originally on land can fly, and those who fly in the air can also go to the sea to lurk, and this world is becoming more and more dangerous. The already ferocious beast can also complete its evolution by hunting for other things, making itself more powerful. Earthquakes and tsunamis are also coming at any time to wreak havoc on the earth.

Mankind finally realized its mistake, immediately stopped the war, and learned to unite, because only by peace and unity, and jointly resist disasters and mutated beasts, human beings can survive in this desolate world, so far, according to the situation at that time, human beings are redivided into three alliances, namely: the Chinese League, the European Union and the African Union. The leaders and members of the three alliances are elected by the three leagues, and they discuss and make decisions together through voting.

Of course, it's not just animals and plants that mutate, after that war, human beings also found that their bodies became different from before, their physical strength was slowly increasing, and their strength was getting bigger and bigger, and they began to be able to compete with some weak mutated beasts, and in the end, each alliance also opened up its own unique cultivation method to make itself stronger, and the humans who could cultivate would be collectively called the aliens, and with the increase and gradual strengthening of the aliens, in the end, human beings slowly entered the formal and self-preservation. But by this time, the number of human beings was less than one-tenth of what it had been.

Human beings call mutated beasts and plants commonly known as alien beasts, in the hunting of alien beasts, human beings have found crystals in the body of each alien beast, which is the origin of the entire alien beast, containing amazing energy, which can be used for cultivation and manufacturing weapons, this crystal is called beast crystal, and beast crystals have played an irreplaceable role in the future development of human beings.

That year was called the year of the destruction of the world and the first year of creation by later people.
