Pokémon: A Demon King Guard at the Start

By accident, Huang Yu transmigrates into the world of Pokemon and binds with the All-Star Sparkling Pokedex system — as long as he defeats now-famous or future-famous trainers, he can obtain information on the wild shiny forms of the same species as their ace Pokemon!

So he decisively sets out on a very different path:

Challenge the strong, strip them bare of every bit of "sheep wool"; pursue shinies, and complete the Pokedex.

Until one day, Xiaozhi looks at the dazzling companions around him and can't help asking:

"Why are your Pokemon... all shining?"

Huang Yu smiles faintly:

"Well, beat me first and I'll tell you."
