Adapted from the original post on Tianya Community titled "Psychologist Zhen Xinjian", with a prequel "The Massacre of the Psychologist's Family". Zhen Xinjian is a hypnotist proficient in psychology. Several bizarre murder cases have occurred in the city: a prostitute suddenly stabs her cheating partner, a driver runs over pedestrians, and a delivery man abruptly attacks a customer during a delivery... All these suspects lost consciousness after receiving a phone call or WeChat message, acted violently, and have no recollection of committing the crime afterward, even though the suspects and victims are strangers. The police found no leads and sought help from a psychologist, who deduced that they had been hypnotized. The quirky girl Miao Miao, a computer expert, insisted on joining the investigation. The police found hacker A Qiang through audio emission servers and signatures. It turned out that a man in black had him design the server and had bought a fake base station transmitter from him. A plan emerged to control the city through criminal audio in a 'Urban Apocalypse' scheme.
