The two novels,'The Rebirth of the Yongzheng Concubine' and 'Humble Girl,' are both suitable for you. The female lead of "The Reborn Concubine of Yongzheng" was the most beloved concubine of Yongzheng. She didn't want to live with hatred after her rebirth, but she couldn't let the tragedy repeat itself. The female protagonist of "Humble Girl" was reborn at the age of thirteen after being brutally killed in her previous life. She transformed into a vengeful demon to kill them one by one. I hope you like this fairy's recommendation. Muah ~😗
