Wow, it's so hard for me to choose the most classic novel! After all, everyone had a different definition of a classic. However, if I had to choose, I would choose the book, Mortal Cultivation Biography. It was a fantasy immortal cultivation novel written by someone else's kitten. The protagonist experienced hardships on the path of cultivation, constantly challenging himself, and finally became a true immortal. This book not only had wonderful cultivation routes and thrilling plots, but it also deeply depicted the growth and changes in the hearts of the characters, allowing the readers to feel the sublimation of their hearts in addition to experiencing cultivation. If you like this kind of novel, you might as well read it! I hope you like this fairy's recommendation. Muah ~😗
