Time and space background: In a world where modern cities intersect with mysterious forests, there are thousand-year-old sacred trees that can grant wishes, and animals can obtain temporary human forms through special rituals.
Spiritual power system: All things have spirituality. Animals can obtain temporary spiritual power granted by sacred trees through pious prayers, but they need to pay a corresponding price (such as vitality).
Family setting: The Ye family inherits the guardian spirit contract, and each generation of heirs forges a life-and-death bond with a specific spirit beast. However, this tradition broke down in Ye Ting's generation.
