After winning the Alola regional championship, Xiaozhi did not want to stand still because he knew that there were more adventures and more magical Pokémon waiting for him to explore. At this time, Dr. Sakuragi sent an invitation to Dr. Oak to participate in academic research. The subject of the research was the topic of Cang Xiang. Cang Xiang appeared frequently in the past few years. Everyone was wondering whether it was because of the appearance of the "Destined One". After Xiaozhi heard this, he followed Dr. Oak to the Galar region.
