A strange and fascinating fragrance suddenly appeared in the market. Anyone who was infected had a drastic change in temperament, and some people died in strange ways one after another. The Yamen was at a loss and had no choice but to find a son from a family who was well versed in spices and pharmacology, and teamed up with the thoughtful head catcher to conduct a thorough investigation. Following a wisp of lingering fragrance, the two stepped into layers of fog, uncovering family secrets, entanglements and old injustices. Underneath the seemingly ordinary fragrant ingredients, there is a carefully laid out poisonous plot; behind every clue, there are dust-laden grievances involved. While resisting the intrusion of incense and poison, they dealt with opponents in the dark. They peeled off cocoons in pavilions and shabby alleys, getting closer to the truth step by step, and uncovered the people behind the scenes who used incense as a blade to manipulate people's hearts. The story is based on a series of narcotics cases, in which two people investigate the case side by side, stick to their true intentions and solve the mystery in the treacherous storm.
Purpose: Taking the spice serial murder case as a guide, it describes the good and evil of human nature and the choices between good and evil, showing the core of working together and adhering to justice, and using ancient suspense stories to reveal the tragedy caused by greed and obsession.
