In the year 717 of the Star Calendar, humanity thrives under the Blue Star Federation, having colonized hundreds of worlds—but peace is an illusion. Beneath the glittering surface of interstellar progress lurks the threat of Dark God cultists, whose psychic corruption annihilates fleets and drives soldiers mad. Fang Xing, a seemingly ordinary teenager, awakens in this future after dying on Earth, carrying memories of a life spent as a burnt-out office worker.

With no wealth, no noble lineage, and no access to advanced tech, his only path to survival is martial arts—a brutal, low-resource path designed for bio-engineered humans destined to die on the frontlines. But Fang Xing is not what he seems. As he navigates high school, trains in forbidden techniques, and uncovers the mysterious 'Gate of All Realms' hidden in his mind, he begins to realize his past life holds secrets that could rewrite the Federation’s entire power structure.

With every step, he walks the razor’s edge between becoming a martyr… or the next legend the system never saw coming.
