Doomsday: Slashing My Way Through Campus with My Adopted Sons

The blood rain falls, mutations begin, and the apocalypse arrives.

Ning Bei, a killer tired of the violence and darkness of his former world, returns to his homeland to live a quiet life and enrolls in university.

He never expects the blood rain to descend and the zombies to mutate. By a stroke of luck, he consumes a crystal core and awakens a supernatural ability.

Scarce supplies, zombies everywhere, terrifying mutated beasts, and the side of human nature no one dares look at in the apocalypse.
