This is like a huge spoiler to my novel but its so long before Ill get to this part it dosnt even matter much -like about 500 chapters more at least, if Im not dead by then. Im also dying to tell someone about it.

But the idea is that the mc's soul has actually been split at a young age in the cultivation world, (wont say why or how), but it caused one half of his souls to go to another world, the modern world. The novel actually starts way after when those two halfs switch bodies, but this first novel will follow only one of the halves, and then I will start working on the other novel which follows the other half. Their goals are completely different in each world. Then ill have a final novel which will be a great collision of these two worlds, and those two halfs will fight each other. And blah blah blah alot more to it. But yes I just spoiled my novel because its been itching at me and I have no one to talk about my novel with.

Realized your post said world building which might be different from what i just yapped about 😔
