When Shen Shuyi, a top student in the history department and a former engineer, transmigrated into a sin slave with a lifeless life in the palace, her only thought was to survive.
In this prison with strict hierarchy and indifferent relationships, she used the world as a chessboard and made a huge bet with all her wisdom and courage - on the least favored "wasted son", the frail and sickly second son of the palace, Zhao Jue, who was forgotten by power.
She originally thought that this was just an intellectual investment in which everyone gets what they need. She assisted him, using economic skills and political tactics that transcended the times, to silently build a business empire with unparalleled wealth, shaking the foundation of the dynasty; he protected her and allowed her the freedom to retire with success, wealth and stability.
But she has calculated all the people's hearts in the world, but she has only missed the changes in people's hearts. She had also forgotten her heart - that heart had long been left behind by the taciturn secret guard Mo Chen who handed her half a steamed bun when she was at her most desperate.
When she finally put him on the throne of the Ninth Five Emperors and was about to leave quietly for the warmth that belonged to her, she was shocked to realize that the new king she had created with her own hands looked at her with eyes that no longer showed appreciation and trust.
In those eyes, there were fiery chains mixed with love, paranoia and crazy possessiveness. What he built for her was not a world leading to freedom, but the most gorgeous cage in the name of country and love.
When ideals shine into reality, when love and ideals run counter to each other, and she has won the whole world, how can she win back the long-lost self?
