He Once Broke Through Ten Thousand Enemies with One Sword

I particularly like a character in a book. She is stunningly talented and beautiful. She looks like the snow gathering in the moon, and she once broke through ten thousand enemies with a single sword. If I were to write a fanfic, I would probably write myself as the thigh-hugging junior sister next to her. Nothing to do with feelings, just pure admiration. One day, I really wore books. But, I dressed as her... Intention: self-identity.
