Three years ago, Xue Xiangyi married Kong Lin'an with a generous dowry. During the three years her husband was away in Liangzhou for disaster relief, she single-handedly supported the Kong household, served her mother-in-law, and exhausted her dowry to subsidize household expenses. Unexpectedly, when Kong Lin'an returned, he brought back a co-wife, Lin Yuniang, and a pair of children. Faced with her husband's betrayal, her mother-in-law's greed, and her sister-in-law's framed plots, Xue Xiangyi completely cast aside her forbearance. Relying on her ancestral Baohetang and extraordinary intelligence, she set up traps to expose her sister-in-law's malicious deeds and tear off the Kong family's hypocritical mask. Because of her brilliant medical skills and benevolent heart to save the world, she deeply won the crown prince's appreciation, and finally obtained the empress's imperial decree, was conferred the title of county princess, and openly and properly divorced to get away.
