The female lord is Dayan, the iron-blooded empress sits in charge, the women are at the forefront, and most of the men are kept in captivity. Gu Yanhan was born pure and handsome, but his nature was like a cold blade. He refused to be a bird in a cage and hid in a cold shop in a small town to work as a widower. In the bloody night, the mysterious "Sin Mark Sky Eye" awakens and can see the marks of crime, listen to the lies in the heart, and review the case. He broke the situation like an iceberg and punished evil with a cold heart. Starting from the old child abduction case, he gradually uncovered the "Zhu Yuan Society" criminal network. The powerful female head catcher, the cold empress, and the delicate and powerful prime minister all became associated with him because of the case. They are strong on the outside but cute on the inside. They love candied haws, are afraid of the dark, and sleep with cats in their arms. The contrast between them is full of cuteness; he is extremely cold, but he feeds stray cats every time after collecting the corpses. Unsolved cases pile up, murderous intent is everywhere, and undercurrents surge deep in the forbidden city. Gu Yanhan used his heavenly eye and knife and pen to tear apart the golden powder of the female queen's golden age, vowing to expose all crimes to the light of day.
