Insects, animals, and even the dead transformed into monsters, while those fortunate enough to awaken the ability to wield mana gained classes that allowed them to fight back. Damon, however, didn’t awaken a class. Instead, he encountered a system error, one that granted him a unique power: the ability to wield infinite classes. From Beast Tamer to Sword God, Damon awakens countless classes as he survives the apocalypse alongside a divine being he accidentally summons.
