Liu Mengmeng, a modern medical student, transmigrates into the mute illegitimate daughter of the Duke Zhenguo household in the Dayong Dynasty. Forced to take her legitimate sister's place in a marriage meant to bring good fortune, she weds Xiao Heng, a “sickly wastrel” heir. If he dies within three months, she'll be condemned as a husband-killer and drowned in a pond. In this desperate situation, she uses her modern medical and chemistry knowledge to counter a slow-acting poison and uncover medical traps. She strikes a pact with the seemingly frail but scheming heir: she will keep him alive, and he will help her investigate the injustice done to her birth mother and protect her little brother. From household intrigue to business rivalries, from the imperial court to the battlefield, the two join forces against the schemes of her stepmother, enemy spies, and a century-old family crime. When the truth comes to light, she turns out to be the descendant of a loyal martyr, while his identity proves far beyond anything she imagined... Medicine and political intrigue intertwine, with sweet romance alongside danger. See how this ingenious young doctor and the scheming heir turn the tide and defy fate!
