Li Xin, a disciple of the Qingyun Sect, was born unable to absorb spiritual energy into his body, becoming a useless young man whom everyone could bully. After enduring humiliation from his fellow disciples for three years, he unexpectedly awakens the remnant soul of Cang Xuan, an ancient supreme master, within his sea of consciousness at the brink of despair. The remnant soul does not intervene directly but instead teaches him an unparalleled cultivation technique. Without spiritual roots, he tempers his physical body as an ordinary mortal; without spiritual energy to rely on, he breaks through his limitations one step at a time. The prodigy Zhao Feng relentlessly pressures him, while hidden dangers and murderous plots emerge one after another, and undercurrents surge within the sect. Li Xin conceals his true strength, endures what ordinary people cannot, and through sheer dedication rises against the odds in Qingyun, transforming from an outcast whom anyone could trample into someone who can no longer be ignored.
