The human girl Wang Mo (Xilan) awakens as the master of the Huali Pavilion in a vision of withering plants, and together with the deputy master Yan Nuoyue, protects the Huali Realm that connects the two worlds. Mo Yuan, the master of the Bone Erosion Hall, covets Hua Li's heart and uses the power of shadow to corrode the spiritual veins in an attempt to swallow up both worlds. In the struggle of dual identities, Xilan uncovered the truth behind her mother's disappearance, united human and flower spirit allies, used the power of "thousands of flowers to bloom and close" to fight against the shadows, and finally became the guardian of the balance between the two worlds. And the bond between her and Yan Nuoyue, from estrangement to side by side, has also become stronger and stronger in the flames of war.
