They kinda divide it weirdly; it's in five parts as I can tell, "Wuxia", "Gao Wu", "Fantasy", "Xianxia", and then "Honghuang" (The Flood/Prehistoric Desolation/The Creation Myth/beginnings of foundations of all realities/lots of tribulations and disasters/reality is puppeted by Heavenly Dao, which is puppeted by Hongjun)
1. Isekai to a world without Pokemon (People can still mistake Mewtwo for Frieza)
2. MC gets the Pokemon games where their Pokemons can go into the game and things can be taken out of the game
3. The anime version of the Pokemon world, which has the most world building, is merging with this "Earth", there are dimensional tunnels and rifts of "forbidden zones" (like Legends Arceus)
