My Sister Is the Champion of the Elf League

Traveling to the world of Pokémon, you have Dialga, the God of Time, at the beginning. The most important thing is to have a sister who just became the champion of the Elf League! Tang Yi said that it was a perfect start. Wait, I seem to have a system where cultivating elves is as easy as eating and drinking. "What, my sister has been ostracized from the alliance? Let's go, Dialga. If anyone dares to bully my sister, I will beat him back!" "There are traces of mythical beasts in Antarctica? Tsk, mythical beasts are not something that trainers from the Alliance can deal with. But I am different." From this moment on, trainers all over the world were confused. Why is the younger brother of this championship so awesome? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
