When I Click on a Novel, the Heroine Is Egoistic and Vicious. Is There a Heroine?

I want to read books like "Quick Travel: The Happy Life of the Little Flower Demon". This is a heroine with a healthy outlook on life. Please recommend some cool articles that have a positive outlook on life. By the way, if you can, please recommend something similar to the happy life of the little flower demon. The author's writing is good, the logic is rigorous and there is no language.
