Rules for Traveling Through Multiple Worlds

Chen Xiaofan, the most powerful person in the main world, whose only hobby is lying down. In order to find clues about his grandfather's disappearance, he walked into the world of Naruto, planning to make a quick decision and go home to sleep. But Tsunade blocked the door: "The person who won my bet wants to run away?" He climbed over the wall and went to the world of One Piece. The empress blocked the bow of the boat: "Either you marry me, or I marry you - you have no choice." He escaped from Dragon Ball, Death, Fairy Tail... Bulma dragged him and said, "Lend me your ability to study it." Yoruichi and Rangiku said, "Don't try to escape this time." Erza's sword lay in front of her: "The guild needs you." Chen Xiaofan looked up to the sky and sighed: "I just want to go back and lie down..." All the heroines said in unison: "No." As for those world-devouring monsters? They were more anxious than him: "After this battle, let's talk about you lying down." It's not that he doesn't want to lie down. It's them who really don't agree.
