Pokemon: I Was Already Invincible, but the Reversal System Only Just Arrived

[Invincible] + [Training] + [Fun] + [Ten-yuan choices]

Qin Fan transmigrates to the Pokemon world and discovers he has no golden finger, so he can only train hard and grow stronger.

Decades later, Team Rainbow Rocket invades his world. During a battle with a Legendary Pokemon, Jiang Li travels through time and space.

A System appears, saying it will help Zhou Li make an endless comeback and become the strongest.

Qin Fan falls into deep thought as he looks at the first mission.

[Please defeat Xiao Mao from True Heart Town. He's already obtained a Pokemon and is a fairly well-known young Trainer.]

Qin Fan is speechless. Is this System even human?

I'm already a Legendary Pokemon trainer, and you want me to pick on rookie Xiao Mao?
