A Blind Swordsman's Sword Coffin Novel

At six years old, Li Guanqi killed his abusive, gambling-addicted uncle who had driven his sister to death and threatened to steal the funeral money while their mother lay gravely ill. An old man named Su Xuan witnessed the act and took pity on the child, adopting him. Eight years later, Su Xuan departed, instructing the young swordsman to seek out the Daxia Sword Sect, a school known for virtue rather than wealth. Before leaving, he entrusted Li Guanqi with a mysterious sword coffin, extracting two promises: carry it always on his back, and tell others it is merely an ordinary sword box. Now, bearing this strange coffin instead of a scabbard, Li Guanqi enters the brutal cultivation world with sky-high ambitions. But questions linger—what secrets does the sword coffin hold? Why is a spirit imprisoned within? And who truly was his grandfather, Su Xuan?
