I recommend "I Collect Trash in Ten Thousand Worlds." The author was a novel about supernatural powers. The plot of the novel was that the main character, Little Yama, began picking up trash with a sack on his back. He kept improving his strength by collecting all kinds of special items. This included collecting the talent of scholars, eating Essence Gathering Pills, eating black dragons, and all sorts of ridiculous acts. However, each of these acts could help him increase his cultivation. In addition, the novel also added all kinds of funny elements, which was very suitable for readers who liked to be relaxed and happy. The novel has been completed, and the word count has reached nearly 3,000,000. It should meet your requirements. I hope you like this fairy's recommendation. Muah ~π
