Fang Qi was once the feared "Lord of the Sin Domain" in the underground world, controlling the three major lifebloods of the black market, finance and intelligence. However, at the peak of his power, he was betrayed by his relatives and died. Once he was reborn, he returned to ten years ago - the youthful years when he was still in the police academy and as gentle as jade. Facing the "Novice Village" where the former enemies are still dormant and the power structure has not yet been finalized, Fang Qi decided to go back to the old path and do thunderous things with a polite appearance. He holds the golden finger of memory of his past life and plans his revenge step by step. From the campus to the city, from the black and white to the top political and business leaders, he uses crime as an edge to tear apart the mask of hypocrisy and drag the betrayers into the abyss one by one. When order collapses and evil is rampant, only he is the real rule.
