Apocalypse Reborn: I Serve the Underworld

The world ended once. Zhou Chen remembers every horrifying moment. Reborn days before the apocalypse strikes, he awakens with the Underworld System—a power that demands service to the realm of the dead. No overpowered shortcuts, no easy victories. This is survival earned through blood, cunning, and deals with forces beyond mortal comprehension. Book one of an epic seven-part saga where one man's second chance could mean humanity's salvation... or its final damnation.
