Pokemon, but It's Palworld

All it took was one comment for Yang Lin to be thrown by his own world’s consciousness into the Palworld. Then, thanks to his damn curiosity, he went exploring the world’s history and accidentally passed every tower trial. As a result, the “Calamity” everyone feared was released, and the Palworld was destroyed. Fortunately, this world was only a leaf on the World Tree. Still, since the world had been destroyed because of him, Yang Lin had no choice but to take responsibility. The World Tree sent him to travel through the Pokemon world, where he hopes to earn Arceus’s approval through his own efforts. He’s working hard so that one day, there will be a region in the world called the Palos Islands. “Now! Jetragon, use Beam Comet!” “Anubis! Use Earth Crusher!” “Ash, the Palos Islands are about to open. Keep it up!” “I’ll be waiting for you in the Palos Islands.” In short, this is the story of a castaway roaming the Pokemon world with his Pals. The Palos Islands may eventually become a region in the Pokemon world, and the story may also involve other worlds. PS: Much of the worldbuilding for the Palworld is made up by the author, since Palworld has almost no plot. The blurb doesn’t do the story justice. Please go read the main story.
