During the Jing Dynasty, Su Qingyuan, the concubine of the prime minister's office with excellent medical skills, married the rumored cruel and murderous regent Xiao Jue on behalf of her eldest sister. On her wedding night, she discovered that the regent was actually the seriously injured boy she had rescued. The eldest sister colluded with the prince and was framed many times. Su Qingyuan used her medical skills to save herself, and even revealed that the truth about saving the boy back then contained royal secrets. In the end, she changed from a chess piece to a being who can stand side by side with the regent.
