Starting from the Mental Hospital, Use the System to Analyze Everything

Shi Yun died in a car accident, but his consciousness traveled to a parallel world that seemed modern but was actually filled with ghosts, possessing a young investigator who had just died mysteriously at the "former Qingsong Mental Hospital site". A yellowed letter addressed to the original person, with torn memory photos stuck to the edges, led him to this horrific building that had been abandoned for thirty-seven years. The letter suggested that the original person's death was related to a phenomenon called "cognitive disintegration." As the only hope of survival, a golden finger called the "Secret Analysis System" was activated in his mind.
