In the twelfth year of Yong'an in the Southern Qi Dynasty, Shen Qingque, the commander of the "Qingque Guard" who was once the sharp sword of the country, fell from the clouds overnight and became a prisoner. The family was wronged and there was a blood feud. She was stripped of her muscles and bones and was given as an abandoned son to the crippled prince who was rumored to be frail and surly - Xiao Changyin.
Everyone thought she would die in humiliation in this silent palace. But no one knows how these hands that once held the sharpest blade in the world will stir up the storm in the capital. He is the sickly prince in the eyes of the world, but his deep eyes hide the ambition to overthrow the world; she is the green bird whose wings have been broken, with the flame of revenge burning in her heart.
When the good-for-nothing prince meets the deposed leader, is it a game between chess pieces and chess players, or is it an attraction between similar people? In this game of power with the world as the chessboard, they test each other and use each other, but in the handovers on the edge of life and death, the most dangerous emotions develop. When the fog of the truth was lifted layer by layer, Shen Qingque discovered that her biggest enemy might be her only salvation.
