a new idea(short chapter)

has anyone ever thought about making a world that leads to other worlds, l. because I have, just imagine a dimensional world that has life on it, and every once in a while there's these portals that appear, and those portals that appear,lead to other worlds, for an example like Naruto or one punch man.

I can imagine it now, I could just make a world, the history and everything, but that would mean that I would have to research the different kinds of worlds that would appear, this is a short chapter.

I wonder if I should write a story about that, what do y'all think.
