During the Xining period of the Northern Song Dynasty, Yan Qingshu, the daughter of a tea merchant in the south of the Yangtze River, devoted herself to the art of dividing tea into hundreds of different forms, and transformed it into thousands of things in the cup. In a tea fight that concerns the life and death of her family, the strange "landscapes" she draws with tea foam actually hide border military information! In order to solve the mystery, she formed an indissoluble bond with Lou Xuan, the cold-faced governor of water transport. She used the intensity of the tea soup as a code and the texture of the foam as a map to convey the secret message of war in the fragrance of tea. Yan Qingshu was unwilling to be just a "beauty" who conveyed information. She used her exquisite tea skills as a blade to promote the establishment of the "Tea Supervision Department" and turned the elegant tea-sharing skills into an invisible military snare. This is a silent game in the fragrance of tea. As the foam bubbles up, she stirs up the chaos in the court with her wisdom, making a cup of tea become a weapon that determines the fate of the country.
