Chen Yehai's Detective Diary

It was raining continuously in Nanchang, and a corpse was found wrapped in strange iron wires by the river. There was a faint green mark on the back of the neck that was only visible under ultraviolet light. The police were at a loss and had to turn to consultant Kang Muzhi, a genius with inhuman perception but trapped in sensory hell. He was forced to partner up with Chen Yehai, a forensic doctor who was dormant due to trauma. Following the "rust sound" and chemical traces, he broke into the depths of the abandoned industrial ruins and unexpectedly revealed a rusty nest of creatures cultivated by a crazy "tuner" and eager to "devour" and "purify". When rational reasoning collides and distorts faith, and when the boundaries of science blur and fear the unknown, they must stop this dark ritual that uses human life as bait before the next note of the "Silent Choir" plays. However, after the case was concluded, the strange call from the Yunnan border and the transnational crisis indicated that this was only the prelude to a deeper nightmare.
