Fang Qi was once the dreaded Lord of the Sin Domain in the underworld, controlling its three lifelines: the black market, finance, and intelligence. But at the height of his power, he was betrayed by someone close to him and died without a trace. Reborn in one stroke, he returns to ten years earlier, to his green and gentle days as a student at the police academy. His old enemies are still lying low, and the balance of power has yet to take shape in this “newbie village.” Fang Qi decides to retrace his old path, using a refined appearance to mask his ruthless methods. Armed with the golden finger of memories from his previous life, he proceeds cautiously, laying the groundwork for revenge. From campus to the city, from both sides of the law to the highest levels of politics and business, he wields crime as a blade, tears away hypocritical facades, and drags his betrayers one by one into the abyss. When order collapses and crime runs rampant, he alone is the true rule.
