I recommend a novel that tells the story of the protagonist who accidentally transmigrated to the Naruto world and returned to Earth after obtaining peak strength.

I recommend 'The Door to Time Traversing from Zero' to you! The main character of this book was a Little Zero under the command of the King of All Zero, Lady Fake Ye. He accidentally discovered a portal that allowed him to travel to other worlds. He had transmigrated to the Naruto world and became the inheritor of the Eight Gates Inheritance. He had powerful equipment such as the Dark Space and the Myriad World Mall, and he had become the strongest person in the Ninja World. However, he was not satisfied. He continued to use the transmigration door to enter other worlds to cultivate. Finally, he returned to Earth and began a new adventure. I hope you like this fairy's recommendation. Muah ~😗
