She used modern historical knowledge and ancient craftsmanship to resolve the crisis in the Hou Mansion, but she was forced to get involved in a palace fight because she offended the powerful. At this time, Ye Huaijin, the leader of the "Dark Feather Gang", the largest gang in the world, sneaked into the capital to investigate the truth about the death of his family. The two became connected due to a misunderstanding about "grabbing hydrangea", and they went from being happy enemies to supporting each other. The heroine experienced the pain of her mother being killed by the villainous Queen Mother, and became stronger after self-doubt.
