Elf: a Trainer and a Pokémon

Luo Yu traveled to the Pokémon world and obtained a prop that could actively travel to another world. In another world, there are no humans, only Pokémon, and he has become a wild monster that cannot transform. In his continuous exploration with his partners, he gradually understood the whole world. The Adventurer's Guild is led by Pokémon and releases missions, expedition teams are formed to achieve different goals, and there are many mazes where dangers and treasures coexist... Then, Luo Yu, who traveled between the two worlds, was surprised to find that the treasures obtained in the maze could be carried back to the original world, and he was out of control from then on. Many years later, Luo Yu became a legendary trainer. In another world, he was a legendary expedition leader who had traversed countless mazes. When people ask him about the Pokémon he knows best, the answer is always the Pokémon that Luo Yu has never trained. Faced with everyone's doubts, Luo Yu just smiled and said nothing. No one understands the various monsters better than me. Who knows the pleasure of beating the mythical beast personally.
