It's the End of the World, the Boss Has Mutated Again!

[Survival at the end of the world, alien creatures parasitizing humans, mutated creatures, no system, no rebirth, team development, material collection, partial harem, decisive killing without the Virgin] Unknown planet fragments scattered across the world, and a doomsday catastrophe caused by alien creatures also followed. They occupied most of the human bodies, turning them into terrifying parasites that feed on human flesh and blood. Under the catastrophe, humans, animals, and plants also ushered in mutation and evolution. The difference was that others would only mutate once, but Li Gang mutated once at each stage.

In this way, Li Gang became stronger through mutation again and again, and worked hard to survive with his brothers, friends, and cute girls around him...
