Qingqiu is surrounded by thick fog that never disperses all year round. The clan rules are strict and the clan members are strictly prohibited from touching the thick fog or exploring the outside world. The elders all say that outside the fog is a dangerous world that swallows spiritual power. A Heng, a girl from the fox tribe, has been curious about the world outside the fog since she was a child. By chance, she violated the tribe's rules and touched the thick fog. She actually felt a mysterious pull and arrived at the "Guixu" stone chamber hidden in the fog.
Here, she met the guardian spirit of Qingqiu who had guarded the place for thousands of years, and also revealed the truth that had been hidden by the clan for thousands of years: the thick fog was not a protective barrier, but a seal refined by the ancestors with their hard work and half-life spiritual power, in order to suppress an ancient ferocious beast that fed on spiritual power; outside the fog was the true homeland of the Fox clan. Now that the seal is loosening and the dense fog is gradually dispersing, the ferocious beast is about to break out of the seal, and the three realms will be plunged into catastrophe, and Aheng is the only one who can awaken the power of the ancestors and strengthen the seal.
On the one hand, there is a stable and worry-free life for the tribe, on the other hand, there is a heavy responsibility related to the survival of the tribe and even the three realms. A Heng will embark on a journey full of unknowns and dangers. Not only does she have to awaken the power of her ancestors, but she also has to face the secrets hidden in her clan and the many crises in the outside world. She also has to recognize herself as she grows up, shoulder her own mission, protect Qingqiu, and protect this world that is about to become unbalanced.
