A genius youth, Ye Chen, awakens the hidden class Necromancer—only to be mocked by all for its supposed cost of consuming life span. Yet, blessed with an undying body, he summons a Golden Undead Legion and a Skeletal Dragon, and even brings forth the Demon King Satan himself, shaking the world to its core.
