I recommend an ancient romance novel in which the male and female protagonists compete with each other when they are young. The female protagonist has poison and medical skills. When she grows up, she disguises herself as a man and meets the male protagonist in order to find lost items and go down the mountain with her senior and junior sisters.

The male and female leads were lovers before, so they had met each other when they were young, and they had even competed in martial arts. The female owner is good at poisoning, so she is a doctor. When she grew up, the female protagonist and three other senior sisters went down the mountain to look for items. The woman disguised as a man and happened to meet the male protagonist. Later, she was trapped (I can't remember where she was trapped). It seemed that because he was recuperating, the male protagonist found out that the female protagonist was disguised as a man. They fell in love and got married in the place where they were trapped. The place where the male and female protagonists were trapped had many poisonous insects that the female protagonist liked to study. When she escaped, the female protagonist secretly took out a poisonous insect egg with a dagger. Later, the male protagonist's master and little junior sister found them (I don't remember what happened later). It seemed that the little junior sister also liked the male protagonist. After learning that the male protagonist and the female protagonist were in love, she was unwilling and used the female protagonist's poisonous insect egg dagger. The insect egg entered the blood. The male protagonist misunderstood the female protagonist and asked the female protagonist to save her junior sister. The female protagonist was sad and saved her. In the end, the female protagonist sacrificed herself to save Little Junior Sister. Only then did the male protagonist know that the treatment method was to let the eggs enter the female protagonist's blood. When the male protagonist learned that the female protagonist did not have much time, he sadly carried the female protagonist back to the mountain to beg the female protagonist's master to save the female protagonist.

Ancient romance novels

Answer 1

I recommend the book,"Flirtatious Doctor: The Princess Consort Is Too Tyrannical." The female protagonist was good at medicine and poison. After being forced to go down the mountain, she disguised herself as a man and began to struggle after meeting the male protagonist. This book was in line with the genre of ancient romance novels, and the female protagonist also met the requirements of the question. I hope you like this fairy's recommendation. Muah ~😗
