Lin Nanxi, a modern reader, accidentally transmigrates into the novel while ranting about its plot. She becomes a low-born concubine’s daughter forced into a substitute marriage in the Censor General’s mansion and binds with a system tasked with saving General Wen Huaijin, a doomed side character. Using system items, she empties the royal treasury, outwits treacherous ministers and the incompetent emperor, navigates countless dangers while accompanying the Wen family into exile, and tracks down General Wen’s elder brother. She wholeheartedly aids Wen Huaijin in raising troops to stage a rebellion and overthrow the tyrannical ruler. In the end, the two stay together and live a blissful fulfilling life.
