National Destiny Pokemon: Dark Trainer

[Pokemon] [Pokemon] [Urban] [Spirit Academies] [Transmigration] [National Fate] [System] [Ghost-type] Pokemon have arrived all over the world, and anyone could awaken as a Trainer. A Pokemon National Fate battle arena has appeared. Evil Pokemon are invading. A Pokemon-based social order has emerged. Trainers have a martial arts system too. Is this a high-martial-arts world? How are evil Pokemon different from monsters? I awakened the same System as in Solo Leveling. Yichen transmigrated into the body of an ordinary boy, but retained all the Pokemon knowledge he had accumulated in his previous life. His Starter Pokémon was a Galar Zigzagoon. On the day he transmigrated, Yichen found himself already standing in the Pokemon national battle arena. He smiled disdainfully. Lucario knocked out its opponent with a single punch. Scizor won three battles in a row, and could even handle Ghost-type Pokemon with ease! Longguo had lost five battles in a row. Its territory was being seized, evil Pokemon were invading, and the whole country had fallen into despair. Yichen, a newly awakened Trainer, won his first national battle with ease, earning Longguo a precious chance to catch its breath! But when Yichen received the national battle Pokemon reward, Gastly, everyone looked at me in terror... What secrets are the Ghost-type Pokemon of this world hiding?!
