I Became the Undead God of Necromancy

Synopsis

Transmigrated into a sewer scavenger, Wu Ju awakens the ultimate cheat ability known as the Extract Talent, allowing him to plunder attributes whenever he slays a monster. Armed with a single skull staff, he slaughters hordes of rotting corpses in secret realms, summons a game breaking skeleton named Ergouzi, and withstands dark forces to complete his class change. While others still struggle to save gold coins for their class changes, Wu Ju leads his invincible skeleton army on a path toward slaying gods.
