Crossing the true dragon realm, and you call me Little Locke?

He transmigrated to the world of Cassialo, a world inhabited by dragons, gods, and a magical network. The good news was that Shuoyang was transmigrated into a true dragon who could naturally grow stronger simply by eating and sleeping. He was even a Celestial Dragon, a spirit dragon species comparable in strength to a golden dragon. But just as he was about to live a life of leisure and wait until his youth, preparing to continue this leisurely existence, the Rock Kingdom System he brought with him suddenly activated. The system called him Little Rock, gave him ten Poké Balls and a White Tree Seed, and instructed him to capture Pokémon, build a Pokémon home, and establish the Rock Kingdom with other Little Rocks. Shuoyang was completely bewildered. "Where did these kinds of Pokémon come from in this world?" "Do I look like a dragon-type Pokémon? Should I catch myself?" So, several years later, when the sacred white tree spanned the heavens and earth, and Pokémon of all types and colors filled the seas, land, and skies, and newborn dragons were about to embark on their journeys, Shuoyang, now the chosen one of the white trees and the crowned Dragon King, appeared out of nowhere. He took out three Poké Balls and asked kindly, "Wise little white dragon!" "Would you like this ordinary, dazzling light blue one? Or this stubborn Sparky? Or perhaps this outstanding, top-tier Meowth?" (ps: pseudo-D&D, Pokémon story, pure dragon story.)
