In order to redeem the blood debt of his ancestors, Yun Yao burned incense and knelt in the ancestral hall for three days, but on a thunderstorm night he lit the ancestral tablet with his own hands, triggering the backlash of a centuries-old evil. Jiang Ye, an unknown ghost figure who walked out of the ashes of the memorial tablet, was actually the stand-in puppet who was sacrificed alive back then. He said nothing, just followed Yun Yao step by step, using his soul as a guide to tear open the seal of the family's secret history. When the last tablet turned into ashes, Yun Yao realized that he was the real sacrifice, and Jiang Ye was the only living evil spirit willing to change his destiny for him.
