Can you recommend an assassin magic novel with a female protagonist dressed as a man?

I don't remember the title of the online novel. There are quite a lot of such novels. It's a headache to write what you know…
The male and female leads are in the same college and it's a "dormitory"

Answer 1

I recommend a novel to you. It's called " Empty Mountain Alliance ". It's an ancient romance novel. The female protagonist was a reborn woman, reborn into ancient times and transmigrated to an imaginary country. She began to become a female assassin and began a series of stories about power and revenge. If you like cross-dressing assassins and magical stories, this book might satisfy your taste. I hope you like my recommendation.
