What is a Pokémon Trainer?

Story of: What is a Pokémon Trainer?

[Pokémon + time travel + humanoid Pokémon + world line convergence + parallel world] [If you don't want to read tactics, you can skip it. There are only a few chapters in total. No more than ten chapters in the first hundred chapters, and there are basically no chapters after that] Zhou Yuan found himself back to five years ago. He thought he had the Urban Dragon Aotian script, but his mother's words made him dumbfounded, "When are you going to buy the initial Pokémon eggs?" Unexpectedly, he got the Pokémon World script. He started with a dog, and all his equipment depended on explosion (fog). As time went by, Zhou Yuan found something wrong. Isn't this the Pokémon World? Why is there no enemy that can match my strength?
