Doomsday System: I Declare War on the World

Five years after the zombie virus outbreak, the City of Doom has become a living hell. Lin Ye struggles to survive among the ruins with his younger sister. After enduring untold hardships, they finally reach the isolation wall, only to face the military's merciless guns.

“You absolutely cannot leave the City of Doom.”

A gunshot rang out. His sister fell in a pool of blood.

Just as despair takes hold, a mysterious System descends:

“Would you like to activate the Apocalypse System and declare war on the entire world?”

Lin Ye accepts, becoming an avenger from that moment on.

He controls zombies, builds a faction, uncovers the military's conspiracy, and proclaims to the world:

“I will bring this apocalypse to an end.”
