The protagonist, Li Jianjun, accidentally transmigrates into a world full of schemes, hypocrisy, and moral blackmail, into a Siheyuan where social maneuvering and backstabbing are everyday affairs. Faced with neighbors who seem righteous on the surface but harbor ulterior motives, he resolves to shatter these twisted rules. He will no longer be an honest man whom anyone can exploit, but will fight these worse-than-beasts hypocrites by embracing evil himself. His motto is: "If others are ruthless, I'll be even more ruthless. If others are devious, I'll be even darker!" Li Jianjun swears to tear off every mask in this world, refusing to be bullied by parasites, ingrates, and the like. He will become a singular force defending his dignity and what is right.
