Xiao Jingrui, a modern rich young master, transmigrates into the body of a seventh-rank county magistrate in Qingzhou and is thrown into a murder scene from the start.
Qingzhou looks prosperous on the surface, but undercurrents run deep. Powerful families collude and corrupt officials abuse their authority. Solving cases is his only way to stay alive and rise through the ranks.
A "Case Investigation System" suddenly appears in his mind. Every case he solves unlocks a ridiculous yet useful skill: retracing evidence, logical deduction, identifying thieves by the sound of the wind...
He joins forces with the sharp-tongued female coroner Liu Hanxue. One uses modern deduction, the other ancient forensic methods, and together they specialize in solving all kinds of strange and unjust cases.
From a man's corpse in a well to a poisoned young woman, from the powerful families' corruption to a secret drug from the former dynasty, every case connects, and danger grows with every step.
With the System at his side, even a carefree life can lead to solved cases. Digging to the bottom, he discovers that even his mentor is the mastermind!
Watch as he uses his wits and wisecracks to turn the tables in the ancient court and rise to the peak of power!
