You and the Spring Breeze Go Together

I'm Looking for a Book, Please.

I want to read a book like "Rebirth in the Apocalypse, I Have Nothing to Do". The heroine seems to be in some kind of camp in the apocalypse. There is a CP. The hero seems to be an experimental subject. The heroine's thunder weapon is a whip made from the bones of the heroine's body. I can't remember the title of the book. Netizens can help me find it.
