I recommend the novel "Going Back to Ancient Times for Surgery." The female protagonist, Fan Yurou, was a doctor who died of exhaustion and was reborn in ancient times. Because she had saved a masked man, she had accidentally been targeted by him. The male protagonist was indifferent to everything in the world until her intrusion gave him the motivation to live again. This novel was filled with medical subjects and historical background. The plot was compact and the characters were very vivid. I hope you like this fairy's recommendation. Muah ~😗
