Orphaned by tragedy at six, Li Guanqi killed his abusive uncle to protect his mother, only to be taken in by the mysterious Su Xuan. A decade later, he embarks on his journey to the Daxia Sword Sect, carrying a cryptic sword coffin on his back—a burden laden with secrets Su Xuan forbade him to reveal. Within its lacquered wood lies a trapped spirit, a riddle waiting to be solved, and the key to uncovering his grandfather's true identity. His sister worked to death, his mother ravaged by illness, and his uncle's greed consuming everything—Li Guanqi's blade became an instrument of justice. Yet mercy came in the form of Su Xuan, an old sage who saw potential in the desperate boy. Eight years of training forged him into a swordbearer unlike any other, his back burdened not by a simple scabbard, but by a coffin meant to entomb legendary blades. Now, stepping into the blood-soaked realm of cultivation with ambitions that pierce the heavens, he must unravel the mysteries bound within his cursed artifact and discover the truth of his lineage.
