During the Taiping period of Dayin, the nine-tailed fox Lingsu and the black python Xuanyuan ran a teahouse in Tingfeng Xiaozhu, Shangjing, secretly guarding all living beings. Under the blue-grey moonlight, strange events such as the demon in the painting and the heart-eating Gu occurred frequently, implicating the conspiracy between the Yongning Marquis Mansion and the Yin and Yang Division, and also exposed the ambition of the Bone Demon to subvert the dynasty with the Ten Thousand Soul Banner. Lingsu, Xuanyuan and Yushi Shen Qingci formed an alliance, and from Wangyou Valley to the deep courtyard of the palace, they cracked the secrets of the Soul-fixing Pearl and the old grudges of Qingqiu, and fought against the puppets and snake clan traitors controlled by evil magic. When the fused Green Fox Pendant and Zhenlong Pendant purify the last fragment of the Ten Thousand Souls Banner, the crisis is temporarily over. However, the remaining warmth of the jade pendants still lingers, indicating a deeper fate and unknown challenges. The three of them stand side by side, using their gleam to fight against the darkness of the world.
