It turns out this world is merely a universe born from the random evolution of intelligent code written by an engineer.
Countless universes like it exist at the same time.
Rats and cockroaches, cats and dogs, snakes and insects, zombies, xenomorphs, robots...
Every kind of creature and every sort of technology has its own universe.
Now, the engineer wants to keep only one universe.
The elites from every universe will fight to the death in the Cosmic Arena, battling endlessly for first place.
Xiong Yu, from Human Universe No. 666, is known as the Ghost and is a god with a sniper rifle.
He heads to the arena alone. Cats, dogs, snakes, insects, elite troops, or heavy armor, all will become ghosts beneath his gun.
