Where Shadows Dwell

When the body of a wealthy businessman was found in an abandoned factory, and the strange blood-lettered symbols beside him pointed to the dusty evil, Sheriff Lin Yu thought it was just a complicated revenge. However, a second body, a falsified history, and provocative anonymous phone calls follow one after another, and he finds himself falling into an elaborate maze. The opponent never appears but is everywhere. He can invade the core of the police station, leave microscopic symbolic art on corpses, and even control the daily life of the town. This is not about chasing a murderer but about being hunted. Lin Yu and the newly transferred sharp policewoman Su Qing face Cui Han, an unprecedented enemy. Cui Han, a 25-year-old internet ghost living in absolute darkness. Beneath the pale and frail appearance is extreme rationality and utter emptiness. He sees humans as inefficient programs and the world as a boring sandbox. The crime committed against him was not an atrocity but a social experiment to verify the "meaninglessness of existence." As the investigation deepens, a vast shadow of psychological manipulation involving transnational smuggling emerges. Pei Yu, a son of a wealthy family, volunteered to become Cui Han's minion and enjoy this dangerous game; forensic doctor Qin He received a private "greeting" from the murderer and was forced to look directly at the abyss of nothingness behind his career. Lin Yu must stay rational in the layers of "experiments" designed by Cui Han, and find gaps for counterattack amidst the secret language of symbols, the crushing of technology and the test of human nature. This is a war between justice and nothingness, a showdown between order and chaos. When the observers become tired and the experiment enters the final stage, what Qingping Town faces will no longer be individual murder but a cold deconstruction of the foundation of society. The truth may be more despairing than the sin.
