Modern ancient book restorer Shen Zhaoning traveled through time and became an abandoned concubine in the cold palace of Nanliang. He and the ruthless powerful minister Xie Yanzhi started a game about history books and power in the mad palace at night. In the mad palace, the mysterious maid Bai Zhi babbles endlessly, the housekeeper, Grandma Li, secretly burns forbidden books, the female thief Yan Qiniang steals the fragments of the truth, and the silent mute Xiaotan draws the underground secret passage - every page of the restored ancient book is a buried deadly chess piece. When Shen Zhaoning discovers that his repair technique is the secret technique of the previous dynasty, Xie Yanzhi's ambition to restore the country and her obsession with the historical truth will eventually tear this man-eating palace apart.
