During the day, he is a criminal psychology consultant specially hired by the police station, using his genius profiling to help solve bizarre murder cases.
At night, he is a "blueprinter" in the shadows of the city, carefully designing perfect crime scenes.

Su Qing, the criminal investigation captain, has never seen such a consultant: Lin Mo can restore the personality of the murderer in three minutes, but only needs a cup of milk tea as reward after solving the case. Until she discovered that the deceased in all the cases he helped to detect pointed to a cover-up of a girl's death five years ago - and the deceased was Lin Mo's biological sister.
"Are you using the police to avenge you?" Su Qing asked tremblingly as the gun was pointed at him.
Lin Mo calmly unbuttoned his shirt, revealing the old scar on his heart: "No, I am planning a bigger trial. And you, including you, Su Qing, are all my jury members."
