I recommend the two novels,"Comic Series: Two-Dimensional Traveler" and "Journey to the Heavens, Time and Space," to you. The main character of "Comic Series: 2D Traveler", Jiang Yuanchong, had spent a long time in the Naruto World. He wanted to go to another world to relax, so he began his journey to another world. The protagonist of "Journey to the Heavens, Time, and Space" traveled to the Naruto World with the space-time auxiliary ability. The route covered the Nine Cauldrons, Marvel, PC, Panlong, Primordial, and other worlds. I hope you like this fairy's recommendation. Muah ~๐
