In a remote village in western Hunan, Shen Yan, the successor of Nuo opera, presided over an exorcism ceremony. Children in the village are mysteriously comatose. The cause is unknown and the traditional Nuo ritual is ineffective. In desperation, Shen Yan took the risk and tried to recruit the powerful but costly "Judge" Nuo Mian. An unexpected incident occurred during the process of praying to the gods. The judge's face was shattered and the Yin energy was violent. Wu Chang, who calls himself "Xie Qi" and is on the run from the underworld, is accidentally summoned to possess Shen Yan. In the chaos, Shen Yan reached a temporary "contract" with Xie Qi in order to save the children: Xie Qi used Shen Yan's body to cast spells to save people, and Shen Yan paid Yangshou. . . .
