Demon Vein Detective

This novel centers on the fated backlash of the demon bloodline and a criminal investigator's professional duties. The protagonist, Shen Yan, bears the remnant soul of Bai Jiu, a white fox who failed to overcome a tribulation, and has the supernatural ability to see resentment and the souls of the dead. Each time Shen Yan uses the power of his demon bloodline, his body deteriorates and his lifespan shortens accordingly. Shen Yan longs to solve the cold case of his mother's murder nineteen years ago, while also carrying the responsibility of solving present-day murder cases. He constantly weighs the threat that using his demon bloodline will cost him years of life against his determination to uncover the truth and save the innocent. This is the novel's central conflict of fate.

The novel also explores the opposition and eventual integration of scientific investigation and supernatural abilities. The heroine, Lin Shuying, believes in trace evidence analysis, stressing the objectivity of the chain of physical evidence and the rigor of logical deduction. Shen Yan relies on his demon bloodline to pinpoint the source of resentment and perceive anomalies beyond the notice of ordinary people. At first, Lin Shuying questions the basis for Shen Yan's conclusions, while Shen Yan is constrained by criminal investigation regulations and cannot publicly reveal his abilities. Their collaboration lets them make up for each other's shortcomings. Shen Yan uses his abilities to guide the investigation, while Lin Shuying uses modern forensic techniques to turn supernatural traces into admissible evidence. The two approaches move from conflict to cooperation, bringing the novel's perspectives into harmony.
