Xu Zhitang married into the Jing'an Marquis Manor carrying the malice displacement system left by her mother. Any malice directed at her would backlash onto what the perpetrator cared about most. The members of the Marquis Manor repeatedly plotted to harm her, but all suffered the consequences of their own actions. While counter-attacking and maneuvering, she investigated the hidden truth of her mother's death in the water transport, uncovering evidence that the Marquis Manor embezzled military rations. Ultimately, she exposed the truth in public, causing the Marquis Manor to fall, clearing her mother's name, obtaining the Emperor's permission to divorce, taking back her family property to revitalize her trading house, and living out her own life.
