The First Female Knight of Zhongzhou

As an ordinary person, Lin Xile always feels out of place whenever she takes a good look at herself. There's the good-for-nothing young man who's about to be dumped by his fiancée, the wealthy young master who's suddenly become a completely different person, a genius radiating a terrifying aura like some chosen hero, and a little beggar who seems to be talking to something. How did all these strange people end up in her social circle?

P.S. Gender bender. Readers with other preferences should enter with caution.
