In a world shattered by invasions from the Demon, Beast, Insect, and Mechanical Worlds, humanity clings to survival through divine blessings and ancient systems. At the age of twelve, every child receives a class—a destiny carved into their soul. But for one boy, that destiny changes everything.
Ray, born in a quiet, struggling village, awakens to the rare and feared Necromancer class. But unlike others, he's chosen by Seventeen, a unique and sentient System that unlocks power beyond imagination. His awakening triggers a miracle: every child in the village gains rare or powerful classes, turning the once-forgotten place into a blessed land.
As Ray begins to level up, he unlocks a hidden Domain—a mysterious realm only he can control. Inside it, he can grow beasts, plants, and weapons, raise armies of the dead, and summon loyal undead like Necromancer Warcha, a general who may one day rival even Ray himself.
With dimensional gates opening across the continent, deadly ranking trials in the academy, and gods watching from above, Ray must grow stronger—not just to protect his village and family, but to survive the war looming between realms.
Slowly, he begins to change. From a quiet child to a cunning summoner, from soft-hearted to shameless, Ray walks the line between hope and darkness… and only his choices will decide which side he truly belongs to.
