The earth collided with another world, and scarlet rain swept the world. Zombies are rampant, alien monsters are coming, and humans are struggling in a double apocalypse. Ye Xing, an experimental subject abandoned deep in the ruins, climbed out of the laboratory in the mountain of corpses and sea of blood. Kill zombies with your left hand to plunder evolution points, and kill alien monsters with your right hand to extract extraordinary genes. While everyone was still fighting for a piece of bread, he had silently stacked up the God-killing buff. Until that day, the projection of gods from other worlds comes and wants to obliterate this world. Ye Xing jumped into the air and pointed his knife at the gods: "The day you come, you will have stepped into the grave." Behind him, there is an endless wave of zombies and monsters listening to his orders.
