Xu Mo, an ordinary college student, accidentally obtained a magical "Hong Kong Code Dictionary". From then on, he can understand and decipher all the shady code words in the Hong Kong world. But he has a fatal flaw - he can only speak modern Internet slang, saying "brothers of the same heart" as "old iron double click 666", "big brother wise" as "YYDS", and "give me face" as "are you polite?" Every slip of the tongue can cause laughter and chaos, but it also helps him save the day by accident. What's even weirder is that these modern memes have actually become a new popular code word in the Hong Kong variety show world, and even the most vicious club bosses have begun to use "The Magic of Love in Circles" as a code to communicate with each other.
Xu Mo originally wanted to work quietly as a translator, but the system forced him to complete the task of "Hong Kong Comprehensive Talker": control Yau Tsim Mong, take down the four major associations, and smash the consortium behind the scenes. What's even more troublesome is that there is a violent policewoman Hua Lao beside him who is staring at him and believes that he is the newly emerged mysterious code master. Faced with pursuits, undercover agents, and conspiracies, Xu Mo could only use his "tough talk" and "wrong code words" to embark on a counterattack in the world of Hong Kong dramas that would make people laugh to death without paying for their lives.
