Shen Zhiyi was originally the only daughter of the former imperial physician. Her family was wiped out because she was involved in palace secrets. She entered the palace anonymously as a maid and was assigned to the cold palace where no one cared. She relied on her family's medical skills to save the cold palace concubine, and was accidentally involved in the power game between the queen mother, the noble concubine and the emperor. From a persecuted low-level palace maid to the "medical eye" that the emperor secretly relies on, she uses medicinal stones as a blade and human hearts as a chess piece. While protecting herself, she gradually uncovers the truth about the injustice done to her family, helps the emperor consolidate his imperial power, and clears away the malaise in the government and the public. In the end, she not only rehabilitated her family, but also won the respect of the emperor with her merits and wisdom. She grew from an unknown maid in the cold palace to a empress with a virtuous mother and a master of skills, and achieved a gorgeous counterattack that transcended class and hatred.
