The Ming Dynasty court seems calm, but in fact there is an undercurrent. The young catcher Shen Yanqiu is famous in Shuntian Mansion for his unique skills of "recreating the scene". However, while investigating the murder of the Minister of Rites in the secret room, he encounters Su Qingwu, the master of Qingque Pavilion who is disguised as a man. This strange woman, who is famous for forging ancient paintings, actually holds the same blue bird pattern jade pendant as the murder case. When the "Human Scanner" meets the "top counterfeiter", the two are forced to form a temporary partner to pursue the murderer in clues that are difficult to distinguish between true and false. From the secret room of the Ministry of Rites to the underground palace of the imperial mausoleum, every strange case hides a code made of mother-of-pearl, cinnabar, and beeswax, and what is involved behind it is the "Qingque Project" that is enough to subvert the court. Shen Yanqiu's scabbard contained half of the jade pendant left by her mother, and Su Qingwu's scroll contained the truth about his father's disappearance. When the two fragments were put together, they discovered that this cooperation that began with suspicion had already intertwined their fate into an inextricable knot.
