Zombie System: Leveling in the Mage World

Mana returns to the modern world, and with it, monsters begin appearing form dimensional tears known as Rifts. Monsters from myth stream out from them, threatening humanity. Mages rise up to fight these monsters, and in this world, Damien Wang is nothing but a lowly porter, carrying equipment for mages while they fight. One day, Damien is betrayed and sacrificed by a group of mages. Instead of facing death, however, he finds Undeath. Wielding mastery over death itself, watch as Damien rises to the top of the world with the might of the undead behind him.
