The fusion of worlds caused the expansion of the earth, and various products from other worlds began to appear in this world with the earth as the center.
What is the most intuitive manifestation, you ask? The most intuitive manifestation is the various continents that appear on the earth. You can see anything on these continents.
Martial spirits, strange fires, Pokémon, anti-matter legions and so on.
All in all, I wish everyone who comes to Earth a happy journey.
