The protagonist Lin Yu accidentally awakens the Pokémon system one day when he gets Pokémon. The system is only a small help on his growth path, and it is more about the protagonist's own efforts. This article has a single female protagonist. The early chapters are slow to gain traction, but the later chapters are more exciting. I hope you can read it. (The first 14 chapters are indeed not well conceived, but things will get better starting from chapter 15)
