On her wedding day, Shen Ruoyan was told by her fiancé Wei Zhan that she would marry her newly widowed cousin Liu Qingyue as his equal wife, and that she was pregnant with a posthumous child. Shen Ruoyan exposed the time loophole on the spot, exposed the two's affair, broke off the engagement and canceled the arms agreement with the General's Mansion. The Wei family thought they could take control of the Shen family, but unexpectedly Shen Ruoyan took charge of the family business, made a lot of money by opening up routes to the South Seas, and became a royal merchant. However, Wei Zhan was defeated and demoted due to lack of armaments. He begged for reconciliation several times but was rejected. In the end, Shen Ruoyan was granted the title of protector of the country and imperial merchants, and the Wei family completely declined.
