In the fifth year of Tianming, Xu Youyou, a young maiden of the Xu family, licked and consumed Taisui to preserve her clan, falling into a two-hundred-year slumber. In modern times, the bronze bells of the Xu family ring, and six of her later descendants welcome her return. Xu Youyou uses her extraordinary power to protect her descendants of diverse personalities and repair the fractures within the family. Zhao Wei, a remnant soul from a previous dynasty, covets the Taisui and wreaks havoc, bringing chaos to the mortal world. Using her wits, Xu Youyou deploys the poisonous Taisui to completely eliminate him, and uses her own Taisui divine power to save the severely injured Xu Qinghe. Shedding the curse and shackles of longevity, Xu Youyou remains in the present world to safeguard the warmth and heritage of the Xu family, witnessing its endless continuation.
