Psychology master's graduate Shen Yuan is dragged into the “Land of Mind-Erosion,” where humanity's collective fears take shape as rules and monsters. You must control your thoughts, because “what you fear will come true.” Here, fear is both food and blade. With his ability to “deconstruct the mind,” Shen Yuan struggles to survive amid countless phobias. In the end, he and his companions discover that the deepest “primal fear” is waiting for them to heal it, or... inherit it.
