I Am a Python

Looking for a Book Where the Female Lead Transmigrates Into a Snake and Slowly Cultivates to Immortality! With or Without CP Is Fine!

Please recommend books like this! I'm starving and have completely run out of things to read. If nothing else, recommend a few stories with a crazy female lead. Not something like a dating reality show where she kills people, just a genuinely crazy heroine! Please, kind people, may you get rich and strike it rich overnight!
