Shen Yuan, a master of psychology, was dragged into the "Place of Heart Erosion" - where mankind's collective fear manifests itself into rules and monsters. You must control your thoughts because "whatever you fear will come true." Here, fear is both food and the edge. Shen Yuan relied on his "psychological deconstruction" ability to struggle to survive amidst countless fear symptoms. And he and his companions finally discovered that the deepest "primordial fear" was waiting to be cured by them, or... Inherited.
