Lin Wanxing, the legitimate daughter of the Duke's Palace, saw her grandfather, the prime minister's family, climb up to the position of Duke of the Palace from a poor scholar. The grandfather's family was framed, and the emperor, considering the prime minister's achievements over the years, did not exile the Prime Minister's Palace, but only demoted him to a commoner. Since then, Lin Wanxing, mother and son have lived in dire straits in the Duke's Mansion. The scumbag father married an equal wife, and the equal wife brought a pair of children. Even a fool can understand that this woman is Lin Fangcheng's wife, and these two children... Are naturally their illegitimate children! Now, in exchange for benefits, the scumbag father actually promised Lin Wanxing to the Minister of War in his fifties. However, he did not expect that this daughter, who had always been timid and cowardly, would choose to commit suicide by jumping into the lake. But he never thought that even though the original owner died, a 21st century agent and a lucky star would actually time travel into a person at the same time... From now on, repay a favor! Revenge! In just one year, Lin Wanxing not only helped her grandfather's family reverse the case, but she also became the royal family's favorite and the crown prince's quasi-Crown Princess!
