The day Luo Tianming, a top graduate of a medical academy, receives the nation’s highest medical achievement award, his colleagues treat him to dinner. Just as he proposes to his fiancée, a falling induction cooker hits him and kills him. His soul transmigrates to a parallel Tang Dynasty, to the tenth year of the Zhenguan era, 636 AD, where he becomes the live-in son-in-law of the Wu family in Jingzhou. He married into the family to bring good fortune to their eldest daughter, who was gravely ill, and is treated as a nobody, subjected to wanton humiliation. Once the future Luo Tianming transmigrates, he begins his comeback. Drawing on his modern knowledge, he livestreams, sells products, sets up parcel pickup stations, and puts group-buying tactics to work, recruiting people for crowdfunding until his business reaches heights never seen before or since. He also uses his extraordinary, era-defying medical skills to save countless officials and nobles, even members of the imperial family, and ultimately reaches the pinnacle of life. But Luo Tianming never expected that the future Wu Zetian, who was originally to be summoned to the palace in 637, would fall for him, nearly changing the course of history in this parallel world.
