Escape from Three-Dimensional Space

"I don't know which dimension I come from, I just know that I'm being hunted!" "In order to escape these people, I even reduced myself to the third dimension, but they still won't let me go!" As we all know: one dimensional line two-dimensional surface three dimensional height What about in three dimensions? What does the fourth dimension look like? What do five and six dimensions look like? After a dimensional war that engulfed all universes, an eighth-dimensional creature built a city called Infinite City. There are a large number of creatures from one to seven dimensions living in it. They seem to coexist peacefully, but these creatures from different universes and different dimensions do not seem to be as harmonious as imagined.
