I recommend the following novels to you: " I am a Doujin Male Lead ": The male lead becomes a Doujin male lead in different anime worlds, and travels to Naruto, the alternate world of Re-Start from scratch, Tokyo Saka, One Piece, and other worlds to start his adventures. " Manga Trial ": The main character tests his strength in the anime world, starting from cutting the red pupil and entering the world of Naruto, to fighting through the sky and many other anime worlds to become a strong person. " Traversing through the Dimensional Rift ": The Dimensional Rift leads the protagonist to cross into multiple anime worlds, such as One-Punch Superman, Ghost Blade, and Crimson Eye. He travels in different worlds and starts an easy and combat adventure. I hope you like my recommendation.😗
