In 4220 AD, Earth's civilization successfully promoted to a second-level civilization and mastered the ability to explore interstellar space. As a result, countless space fleets began to explore and develop surrounding galaxies.
In 4500 AD, the Xuannv 2 fleet made a discovery in the Nanmen II system 100 light-years away that shocked the entire human federation.
Here, the corpse of a humanoid creature comparable in size to Jupiter was floating. After a decision by the Federal Supreme Council, it was decided to explore and develop it.
However, the skin of this humanoid creature was as hard as a neutron star and could not be destroyed by conventional means. In the end, an anti-matter bomb was used to finally break a hole in the skin of the humanoid creature's body and obtain the opponent's genetic sample.
But before the fleet had time to study it, a terrifying virus broke out from the body that had been floating here for who knows how many billions of years.
The Xuannv 2 fleet was wiped out in an instant, and the virus spread rapidly, encompassing all galaxies within hundreds of light years in just a few decades.
The powerful human federation with a second-level civilization collapsed. Some humans, animals and plants died directly, and most of them mutated and became zombies.
Some animals mutated into terrifying beasts, and the surviving humans carried out nuclear strikes to clean up the large gatherings of zombies and mutated creatures.
However, in order to preserve the living space, small thermal weapons were used to clean up the remaining zombies and mutated creatures, but the efficiency was extremely slow and once caused heavy casualties.
Until, some powerful warriors who awakened extraordinary power appeared among humans...
