After Rebirth, Quan Houfu Knelt Down and Begged Me for Forgiveness.

Tang Xin, who has excellent medical skills, was reborn after a miserable life of being sold, betrothed, abused by her parents-in-law, exploited by her brother-in-law, and sent off a cliff by a group of crazy horses. In this life, she lives only for herself. It is impossible to let a medical skill go to waste, it is impossible to be filial to the parents-in-law, it is impossible to cultivate a brother-in-law, and it is impossible to keep this prince's house for a lifetime. Whoever loves to be a widow should go; whoever loves to keep a widow should keep it. Anyway, she is not doing it right. Besides, her tall and mighty God of War Prince, who has great military exploits, won't allow it either.
