OMG! I'm the EVIL Monkey King?!

A time traveler awakens the Monkey King's power, but inherits the dark Six-Eared Macaque instead. His sister is killed. To revive her as Nezha, he needs the killer's heart blood. Dark magic corrupts him. Holy light fights back. Before he falls completely, he must shatter the heavens. But can a half‑demon wearing a hero's face truly become the Great Sage?
