Supernatural detective + suspense solving. "Jiangcheng", a second-tier city in contemporary China, is narrated in the first-person "Old Qian" style. The tone is down-to-earth and does not exaggerate supernatural horror. The focus is on case reasoning and the game of human nature. Calm with black humor, despair mixed with self-deprecation. Use fragmented cases to advance the main line and adapt to the writing rule of "only one piece of information is given in a paragraph".
