I think the novel that suits you is "The Phoenix's Glory". The female protagonist was General Jin Xiu in her previous life. She accidentally fell into someone else's trap and died tragically. However, she was reborn. In this life, she was the daughter of a concubine in the Prime Minister's residence. She used her intelligence and wisdom to plot every little thing and finally avenged the blood feud of her previous life. It also involved the identity and life of the female lead. The plot was very exciting. I recommend it to you. I hope you like it. Muah ~
