An Yue is an experienced, sharp-eyed detective who has always worked on the dangerous edge of solving crimes. Meng Hao is a thirteen-year-old boy with extraordinary intelligence. His parents died when he was young, forcing him to mature early, and he has a unique talent and passion for deduction. Fate brings these two seemingly different people together and sets them on a difficult journey of investigation.
The cases they face are always tangled and complex, like mazes. Every crime scene investigation feels like a contest of wits with a cunning opponent. The scenes are often in terrible condition, filled with pungent odors and hidden dangers. They must search painstakingly for clues that may disappear in an instant. They can afford to overlook neither dusty corners nor spaces left in utter disarray.
Clues are often fragmented, like stars scattered across the darkness, and they must use their intelligence and patience to piece them together. Following every faint trace, they travel through every corner of the city: from dark, damp basements to abandoned buildings reaching for the sky, from bustling back alleys filled with all kinds of people to mysterious places under tight security.
The suspects are like ghosts, concealed behind layer upon layer of fog. The pair must face direct threats from ruthless criminals while staying alert to possible conspiracies lurking behind them. During their pursuit, they repeatedly fall into their enemies' traps, with their lives hanging by a thread. But An Yue and Meng Hao never back down. Supporting each other and drawing on their respective strengths and fearless courage, they overcome one crisis after another and struggle onward toward the truth...
