Dimension is originally a mathematical term, "time" means power, and "yuan" means unknown. But this "dimension" is an anime term, which is "dimension". One-dimensional space is a world described by words, two-dimensional is a plane world, three-dimensional is a static three-dimensional world, and four-dimensional is a moving three-dimensional world. Five dimensions and beyond cannot be explained. Anyway, we know that saying "different dimensions" means that the strength is too far apart, just like the difference between god and insect. Look up "dimension" in the encyclopedia. Very detailed.
