18 parts Ongoing In a world where honor is written in scars and betrayal flows like mountain streams, Jin Mu-Won, a low-born disciple of the prestigious Iron Fist Sect, discovers a power that defies death itself. After a fatal betrayal, he awakens an ancient Nano System, a secret machine capable of enhancing his body, analyzing martial techniques, and rewriting the outcomes of his life. Each death sends him back in time to the morning before he fell, leaving the world unchanged-except for him.
As Mu-Won navigates the deadly politics of the sect, rival clans, and monstrous forces hidden within the land, he must mask the true extent of his power, for discovery could bring his own brothers down upon him. Each step forward is a careful balance of cunning, strength, and patience, as he fights to survive, protect allies, and uncover the secrets buried within the Iron Fist Sect and the alien technology that has become part of him.
From clandestine duels in training courtyards to deadly missions in haunted forests, Iron Will is a tale of resilience, strategy, and the relentless pursuit of mastery. It is a story of one boy who learns that true power does not come from avoiding death-but from mastering its echoes.
