Pokémon Arrives, Shrinking the Apocalypse

My name is Bai Tianwu, and I am a time-traveler. After time-traveling, I spent an ordinary ten years in this world. Unexpectedly, under the great changes of the rendezvous of the heaven and earth, all human beings were proportionally reduced to one-twentieth of their original size. The coffee table has become a cliff, the bathtub has become an inland sea, and the green belt of the community has become a forest. That Arceus guy gave everyone a Pokémon and a Pokédex as severance pay. When everyone was confused, only Bai Tianwu was confused, because there were no Pokémon works in this world. Hehe, it seems my time has finally come!
