You Already Have Pokémon, and You Still Want Me to Punch the Trainer?

Traveling to the world of Pokémon, there is no Gosan family and no Dr. Oak. In the beginning, there was only a gangster who wanted to kill Chen Xiaomu, and a black-hearted orphanage who wanted to swallow up all his inheritance. System? Doesn't exist. My golden finger is my fist! When others use Pokémon to fight, I directly knock down the trainer with a naked choke. In this cruel world where Pokémon has gone awry, if you want to survive, you have to be more ferocious than Pokémon and more ruthless than villains! So, will you accept my invitation to fight, or not? (Friendly reminder: This is a battle in the physical sense)
