Cultivating immortality for five hundred years, Blue Star has actually only passed a single night! Chen Fan, a high school senior, wakes up to find his entire family has also returned from another realm: Grandpa has reached Deity Transformation, his mother is at Nascent Soul, and his younger sister is actually the Primordial Saintess. Only he is deemed to be merely at the mid-stage Foundation Establishment, becoming a "weakling" in the eyes of his family. Little do they know, Chen Fan has long since ascended to the peak of Mahayana, wanting only to conceal his cultivation and return to campus. Yet mysterious spiritual veins and martial arts conflicts emerge one after another, and a conspiracy dormant for a thousand years gradually awakens. As the otherworldly crisis approaches Blue Star, can he protect his family and the mortal world?
