Otherworldly Skeleton Evolution

Story:

Upon dying, Jiang Cheng ended up reincarnating into a game world as a skeleton summon that had been revived by a hot female player using necromancy. What's a skeleton summon, you may ask? That's a type of skeleton that's even worse than cannon fodder! But thankfully, he was lucky enough to get a limitless evolutionary system to assist him! That was the moment when a godly skeleton that kills players and wreaks havoc among the NPCs was unleashed into the game.
