In the urban dark network built of steel and concrete, three chess pieces of fate were pushed onto the chessboard:
• Ye Lin, the former ace "Shadow Blade" of the killer organization "Night Owl", ran an antique shop after Jinpen washed his hands, hid the willow leaf dart in his sleeves, and shouldered the blood feud of his sister's mysterious disappearance;
• Lin Shuang, a chemical genius girl, was hunted for exposing the shady story of human experimentation by a pharmaceutical company. She carried homemade poison and incendiary bombs with her, codenamed "Medicine Mist";
• Wen Nuan, a best-selling mystery writer, appears to be an intellectual lady wearing gold-rimmed glasses, but in fact, she is secretly investigating the unsolved "missing girl case" by the police. Her pen name is "Bi Feng".
A bizarre "art poisoning case" involved the three people in the whirlpool: at the auction, the jade jade bracelet was poisoned and killed the buyer. The willow leaf dart left at the scene was engraved with the birthmark pattern of Ye Lin's sister. The illegal drug ingredients that Lin Shuang had exposed were detected in the blood of the deceased. The novel manuscript that Wen Nuan was writing was highly overlapped with the details of the case.
When the "Collectors" organization behind the dark web surfaced - they used young girls as "collections", used drugs to manipulate memories, and trafficked people through antique trading chains - the three female protagonists had to break identity barriers: Ye Lin regained her killer instinct, Lin Shuang traveled around the laboratory and streets making drugs, and Nuan Nuan used the plot of a novel to deduce the logic of the murderer.
As the clues intertwined, they discovered that all the crimes pointed to the "Nightingale Villa Fire" ten years ago, and Ye Lin's missing sister was the prototype of the missing girl in Wen Nuan's novel...
