Extracted into the God of Necromancy

After transmigrating into the body of a lowly sewer cleaner, Wu Ju awakens the ultimate cheat ability—Extraction. Every monster he kills lets him extract and steal its attributes. Armed with nothing but a skeletal staff, he slaughters hordes of rotting corpses inside a Level 5 dungeon, raises an overpowered skeleton companion nicknamed Er Gouzi, and withstands the power of darkness to complete his class advancement. While everyone else is still struggling to earn enough gold for their class change, Wu Ju is already marching down the path of slaying gods, leading his ever-growing Skeleton Legion.
