After Shen Hengwu had her face changed by her eldest sister, she married the weak and deposed emperor in her stead, becoming a political victim of the deposed queen. In the cold palace, she relied on her photographic memory and meticulous thinking, starting from the lowest palace maid, and gradually established her own intelligence network by deciphering the secrets of the palace, discovering poisoning plots, and gathering frustrated palace residents. When the eldest sister wanted to eradicate the enemy, she used her past life memories (not Golden Finger, but real experiences) to rebel against the generals and expose the truth about the family's collusion with foreign enemies. In the end, she helped the deposed emperor to rehabilitate himself. She also transformed from an abandoned chess piece to the master of Fengyi who truly held the power of the harem.
