The modern city "Yunzhou City" hides a gap between the Yin and Yang worlds. The heroine Lin Wanxing accidentally binds the mysterious metaphysics APP "Three Realms Amnesty Order" and takes on tasks in the Three Realms through live broadcast (such as handling supernatural events, mediating Yin and Yang disputes), and gradually reveals the secrets of the APP and her own bloodline. The male protagonist Gu Yan is the director of the "Yin Yang Department" who hides his identity. He is responsible for supervising the order of the human world and the three realms. In the early days, he investigated Lin Wanxing because the APP broke the balance, and later joined forces because of a common goal. The villainous force "The Soul Eater Society" attempts to exploit the loopholes in the APP to swallow the spiritual power of the three realms and subvert the existing order.
