Start with the Two Gods of Time and Space to Travel Through the World of Pokémon

When evil comes, which god will you be the spokesperson for? My name is Lin Fan. I travel through the world of Pokémon at the beginning. I find that it is ten years after Ash won the championship. Ash and many champions have disappeared. The world is facing a crisis. How should I resolve it? The protagonist is Lin Fan, an ordinary person like us who love Pokémon and the Pokémon game. When we watch cartoons, play Pokémon games, or read fan fiction, we are ordinary people who want to travel through time and summon Pokémon to fight. Suddenly one day, we want to depict this passion with the pen in our hands. It may be that I don't understand Pokémon deeply enough, and I feel that the world view of Pokémon is a bit broken, with too many holes to fill, so I will use my own understanding of the world view of Pokémon to describe it. Like-minded friends are welcome to leave your comments. If there are any deficiencies, I will correct them. If you are a poor person, please don't complain.
