Which favorite novels do you recommend about the female protagonist who is good at using poison?

I recommend "The Poisonous Doctor", an ancient romance novel written by a slightly tipsy person. The female protagonist was proficient in medicine and was good at using poison. She was the most unfathomable Tang Sect expert. She entered the palace to steal the time shuttle and was caught by him. However, her old illness unexpectedly relapsed. She used a little medical skills to save him. From then on, not for the sake of her beauty, but for the sake of her full body of poison and medicine. The male protagonist doted on the female protagonist very much. It was a very sweet novel. I hope you like my recommendation, Mwah ~😗
