You Divorced Me for a Noble Lady? I'ii Take My Dowry and Remarry

[The female protagonist's creed: Power and money are a woman's only means to be carefree and unrestrained!] [Strong female lead + satisfying read + competing with the best men in the dynasty] Jiang Yu thought she would live a comfortable life of modest wealth, but when she turned eighteen, one absurd thing after another happened. First, her husband, whom she had supported with money for many years, wanted to marry a noblewoman after becoming the top scholar in the imperial examination, forcing her to leave. Then, the Duke's mansion claimed that she was their legitimate eldest daughter and demanded that she acknowledge her ancestors. This... is clearly a satisfying read! Since that's the case, Jiang Yu won't hold back and will enjoy the thrill to the fullest!
