In 1995, Hong Kong is a chaotic city awash in neon, where black and white blur together. You Zi'an transmigrates to Hong Kong Island and becomes a bottom-tier Four-Nine boy in Hung Hing’s Causeway Bay crew. His daily routine is serving tea and water, slacking off, and doing as little as possible. His greatest ambition is no more than a steaming bowl of clay-pot rice with barbecued pork. He hopes to lie low and make it through the turbulent Hong Kong crime world in peace, but unexpectedly unlocks the all-purpose AFK Secret Identity System. The five max-level identities are all unlocked: the cold-blooded killer, the suited-up thug, the peerless ghost doctor, the king of gamblers, and the night walker… Yet, to his utter surprise, while he idles away his days, these secret identities go into business on their own and secretly become entangled with a host of obsessive, volatile beauties. The cold-blooded killer saves the ice-cold, volatile Inspector Long Jiu, and her obsession reaches its peak. The suited-up thug crushes the Viper Gang and captures the heart of the venomous beauty Ding Yao, who becomes obsessively devoted to him. The king of gamblers dominates the casino world and catches the eye of the stunning beauties around the God of Gamblers. The ghost doctor saves the loved ones of countless underworld heavyweights with his miraculous skills. The night walker takes control of all Hong Kong’s intelligence, leaving the cherished women of powerful figures across the city unable to forget him!
