The Madman Is Here: Shaonian Huaijin

(The protagonist is a girl, but this is not a romance.)

Qi Shaojin lives up to her name: she is young and beautiful, but she hardly lives up to the character "Jin," meaning "cautious." At least, that character does not suit her at all.

Her elders gave her the name "Jin," hoping she would act with caution and think things through before making a move.

But she is a bona fide lunatic.

At last, she got herself killed one time too many. When she woke up, she was in another world...
