I recommend the following two novels to you-"The Rebirth of the Demon Empress" and "After Rebirth, I Have Been Spoiled by the Fifth Prince". The former was about how the female protagonist Murong Jin used ruthless means to live for herself after her rebirth and launched a series of revenge actions, while the latter was about the love story between the female protagonist Nangong Jin and the male protagonist Huangfu Jin after her rebirth. The two of them grew up and fought together in the new era after their rebirth. I hope you like my recommendation. Muah ~
