Starting from the Start as a Slave: I Rise to Greatness, So Why Are You Crying?

Chen Yi, an undercover cop who had risen to become a gang leader, transmigrates to the fictional Great Qian Dynasty, where from the start his stepmother forces him to become a servant. How could he put up with that? If you insist on pushing me around, don't blame me for knowing a few martial arts moves. What? Your younger brother is a constable? Then ask him how he'd feel if his son suddenly went missing. What? You know a crime boss? Then ask him if he wants to go to prison. With both the underworld and the authorities in his hands, he commands the turbulent martial world with one hand and steers the imperial court with the other. He cleans up the court at home and raises the nation's prestige abroad, making a name for himself across the land!
