Chen Yang time-travels to become a disciple of the Lanyue Peak of the Qingyun Sect. His master, Gu Qingyu, fails her golden core formation, loses all her cultivation, and her disciples betray her. With a single oath, Chen Yang binds to the mother-protecting system, learning that his master is destined to be refined into a cauldron. Disguising himself as a Qi-condensation weakling, he awakens the Pure Yang Body, liquidates the traitors, and roots out the elder colluding with the Ghost fiend Sect. Chen Yang takes Gu Qingyu to seek medicine, heal injuries, and make allies. At the sect grand tournament, he slays Li Xuan, exposes the sect master's sacrificial conspiracy, and jointly liberates Gu Qingyu's master. Afflicted by the Taiyin spiritual seed, the two break into the Qianyhu Secret Realm to defuse the crisis, return to Lanyue Peak to become dao companions, and revitalize the peak.
