Xie Guiwan was born from the sea of corpses and mountains of blood of Wusang City, and is the Great Sage of the Merciless Path outside the cause and effect of the Three Realms. To suppress her obsession, she stripped away her six roots of affection and hung them on the Fusang divine tree, but unexpectedly, the strings of affection fell into the mortal world. Accompanied by Shen Budu, the transformation of a begonia from her past life, she traveled all over the mortal world to recover the strings of affection, unraveling one grievance case of mortal obsession after another, and successively breaking bizarre cases trapped by obsession such as the Pei family's bronze mirror, the red jade grievance, and the withered wood maze. On the way to investigate cases and recover the strings of affection, her sealed memories of her past life gradually awakened, and the conspiracy of the heavenly court also surfaced. When all six strings of affection returned to their places and the sealed memories awakened, the fateful battle broke out. Can they fight against the heaven and break free from the destiny already written?
