Shen Qingyi, the concubine of the Yong'an Hou Mansion in Daliang, has a humble biological mother and walks on thin ice in the house. The eldest sister Shen Qingyao is beautiful and arrogant. She is about to enter the palace draft, but she accidentally falls into the water and is disfigured. In order to protect Ronghua, the Hou Mansion forced Shen Qingyi to enter the palace in the name of his sister-in-law.
As soon as you enter the palace gate, it is as deep as the sea. Shen Qingyi relied on his talents and forbearance to survive in the thrilling harem battles. She thought she would only be a chess piece in her life, but unexpectedly discovered that her sister's fall into the water was not an accident. There was another hidden reason behind her mother's death, and the cold-faced and taciturn commander of the forbidden army actually had an unknown relationship with her.
From a substitute to a beloved concubine, from a chess piece to a chess player. When she finally stood at the pinnacle of power, she discovered that it was never the walls and tiles that imprisoned her, but the obsessions and desires deep in the human heart. She will use her lifetime glory to rewrite the shackles of fate that have trapped three generations of women.
