Hey! To meet your needs, I have the following novel recommendations: 1. One Piece: The Fruit of Revolution (Light Fiction-derived Doujinshi novel). Although the main character was not invincible, the story was very interesting. 2. "Naruto System: God Slaying the World"-light novel-derivative doujinshi novel. The protagonist mastered the invincible system and overturned the immortal world. It was very exciting. 3. "One Punch Hunter"-a game novel. The main character can kill any enemy with one punch. It's very refreshing. 4. "Reborn in the Lost Land"-an ancient romance novel. The main character had a golden finger of medical skills and spiritual power that could deal with all kinds of crises. 5. "The Legend of the Dragon King: The Rise of the Golden Dragon"-a light novel-a derivative doujinshi novel. The protagonist controls all the essence of the Golden Dragon King and has the maximum combat strength. I hope these novels can help you find the works you like. If you need anything, you can tell me at any time ~ These are my personal recommendations. I sincerely hope you like them ~
