A marriage decree was sent to the Xie family: the emperor decided to marry Xie Huiyin, the legitimate daughter of the Xie family, to Lu Zheng, the legitimate son of the Zhenbei general's family. Lu Zheng is a well-known "evil dog" in the capital. He is wild and unruly by nature. He kicks the school, grabs roast chicken, and gets into the government office after fighting. The ladies in the capital avoid him. Xie Huiyin is the eldest lady of Renhetang Pharmacy. She keeps an ancestral book "Handbook of Herbs" and wants to practice medicine to help the world live a stable life, but she is forcibly excluded from this marriage. Since resisting the imperial edict was a capital crime, she had no choice but to make a bet with Lu Zheng: she would teach him literature and etiquette, and if he was reborn, she would recognize him as her kin.
She thought her husband was a piece of mud, but she didn't expect that there was real gold buried in the mud - Lu Zheng was not a playboy who couldn't be helped, but a general who had been delayed. She taught him how to read, write, and be a good person, and he protected her hospital and shop; he taught her how to draw a bow and ride a horse, and she taught him restraint and forbearance. A bet turned two people who refused to accept each other into the most compatible couple in the world.
But life is far more complicated than a bet: Xie's pharmacy is being plotted, and there are forces secretly trying to swallow up her family business; the old case of her mother's death, the secrets at the border, and the strife in the court, drag her into the whirlpool one by one. She planned the chess game with her medical skills, and he broke it with her fists. They fought all the way from the drug store in the market to the Golden Palace - she personally taught the "evil dog" to become the champion, but she found that a bigger chess game had just been revealed.
