Taking "rebirth and revenge" as the main line, it combines the elements of "ancient time travel" and "house fighting for power" to tell the story of a low-class concubine in the highly hierarchical Dajing Dynasty. With the help of modern medical knowledge and wisdom, she reveals the truth about the death of her biological mother, fights back against the persecution of her aunt, and finally breaks through the shackles of feudal ethics and realizes her self-worth. The core conflict revolves around "the game of survival under the system of concubine superiority" and "the reshuffle of forces in the change of imperial power", emphasizing the awakening and growth of women in difficult situations.
