Isekai Beauty

This bundle of greatness. She dies in her own world and then is reincarnated on another one. She uses her wisdom and knowledge to outsmart people one after the other. She also helps others. Nominee for best girl awards!

This really reminds me of those manhwa where the person finds a stone or tablet and some old dude who is ridiculously strong lives inside and guides him.

One of the best ones. Definitely OP MC but he's also really laid back. He dies and is sent to a different world where he is able to live life more freely and just enjoy the things around him. It's quite amazing just how he manages to tame a slime and then learn about them.
