The most unlucky thing in Jiang Li's life was being carried into the palace in a gorgeous sedan. Good news, she is not going to be a palace maid, but a queen. Bad news, she is just a stand-in for the long-missing Queen. To make matters worse, the queen disappeared under mysterious circumstances, and everyone in the palace said she would not survive more than three days. Jiang Li looked at the face in the mirror that was 70% similar to her own, as well as the mess deep in the palace that no one dared to touch, and felt a chill in her heart. This is not like being a queen. She is clearly sitting on a chessboard that can be overturned at any time, and is a chess piece at the mercy of others. Everyone says that there is a saying in the palace that "the game of chess determines the fate", and every move involves the life and death of countless people. And she, the substitute queen, is the most insignificant figure in this chess game. From a country girl to becoming the queen of her mother's world overnight, Jiang Li only found it absurd and ridiculous. She has no prominent family background, no extraordinary talents, and she does not have the golden fingers necessary for counterattacking heroines in novels. All she has is a fairly clear mind and a tenacity that refuses to admit defeat. There were overt and covert fights in the palace, and the undercurrent was surging. The missing phoenix seal, the strange ash-grown flowers, and the whispers whispered in dreams every night, all reveal the secrets of the deep palace. Jiang Li must work step by step, looking for clues from seemingly harmless trivial matters, and distinguishing the authenticity from the mouths of concubines who hide their knives in their smiles. She wants to live, not only for herself, but also to uncover the chilling truth behind this stand-in's identity. She is not a real queen, but she has to use her own way to play the game of life and death.
