I recommend the following Naruto Doujinshi novels to you. They are all over a million words, and they don't involve harem or overly fantasizing plots: "The Legend of Tycoon Muye": The novel tells the story of a player who came to Naruto World with a pay-to-win system. Although there is pay-to-win, the author promises not to abuse the owner. He takes a relaxed and refreshing approach. It is both inspirational and touching, and there are also many funny elements. "Selling jars from Naruto" tells the story of a protagonist who transmigrated to the Naruto World and obtained the Universal Trading System. He became stronger as he sold jars. There are many funny elements and powerful artifacts, very suitable for readers who like pranks. [One Piece: Deputy Captain of Death: The story of the protagonist obtaining the Death System in the world of One Piece and becoming stronger.] The plot was very compact and didn't drag on, nor was there any overly imaginative plot. It was very suitable for slightly more serious readers. I hope you like my recommendation. Muah ~ If you have any other needs, let me know at any time ~😗
