On her wedding night, Yunxi is reborn with a system and takes up a dagger to seek revenge on Crown Prince Xiao Jingxing. In her previous life, her entire family was massacred, and all her trusted companions were brutally killed. Just when she thinks victory is within her grasp, she discovers that she is not the only one who has been reborn. Four men are drawn into the game, hidden guards emerge, and a black shadow formed from resentment watches her menacingly. After venturing deep into the main headquarters of the Jin Guards, she uncovers a shocking secret: the system comes from four hundred years in the future, and her mother's soul is trapped within it as well. Given the chance to reset her fate, Yunxi rejects the shortcut of forgetting everything. She kills the Crown Prince, resolves long-standing entanglements, and breaks free from the system's restraints. Letting go of her obsession, she refuses to remain trapped by hatred and joins hands with her companions who have faced life and death alongside her, writing her own new beginning.
