The two tragic deaths were caused by the conspiracy of her husband Xiao Jin who died during the winter vacation, and the concubine Gu Yunshuang's cruel heart. On the day of returning to make a decision, Gu Yunshu gave up his love and asked for an order to keep his integrity. He built a chastity memorial arch and nailed Xiao Jinhan's "death" into an ironclad law. She used the power of the emperor to control the Xiao family, tear apart the hypocritical concubine, check and balance the ignorant sister-in-law, and make the unfaithful people fall from the clouds into the quagmire. Step by step, she sets up a game at every level. She uses her chastity as a chess piece and her life as a bet, and finally makes those who deceive the emperor subdue the law and those who do evil are punished. From being a resentful wife in the back house to being the person in charge of the situation, Gu Yunshu used his pride to write his own chaste words and live a life that no one can bully.
