During the hundred years of the Dayin Dynasty, the imperial power declined and the aristocratic families were divided. I am Xie Qinghe, the daughter of the chief of the Imperial Medical Office. My whole family was executed on charges of "collaborating with the enemy." I escaped by chance and entered the palace anonymously as a maid. Emperor Xiao Yichen already knew my identity and kept me by his side, just like a chess piece.
There are surging undercurrents deep in the palace, with vassal kings making moves outside and powerful ministers wielding power inside. I am equipped with the "Materia Medica" and the star fortune deduction technique, and can predict disasters and epidemics and observe the fate of the country. Not only must he investigate the murder case, but he must also survive in this cannibalistic palace fight. He is cold-hearted and caressing every step; I pretend to be a pig and eat the tiger, using medicine to plan the situation. Save the common people and clear up the grievances. Who said that women can't decide the future?
