Life Simulation: From Orphan to Legend

Orin Kumar died young—just another forgotten cancer patient in a cold hospital bed. But fate had other plans. Reborn in a world where portals unleash monsters and strength determines status, Orin awakens in the body of a ten-year-old orphan, powerless and alone. In this society, everyone gains a class and the ability to level up at eighteen. The strong become Professionals—monster slayers, portal explorers, heroes. The weak are left behind. But Orin’s new life comes with an extraordinary twist: a mysterious Life Simulator that can predict and replay his entire future once per week. Each simulation grants him a single reward... and a chance to do better next time. On his first run, Orin draws the rarest talent of all: Black-Rank – Mortal Body Accession. He cannot use mana. He cannot cultivate. He cannot wield the world’s power like others. But in exchange? His body has no limits. As the simulator guides him through hardship, death, and growth, Orin must forge his own path in a world where power is everything—and he has none of the tools others take for granted. Can a boy with no mana rise above those born to conquer? When strength can't be borrowed, it must be earned—one simulation at a time.
