Ooooh, a looong story to sink our teeth into sounds amazing! I mainly love SF, too. Well, an urban fantasy and super hero stories. I wonder if there is any Korean SF, urban fantasy or superhero webnovels? Do you by chance know of any that fit those genres?

I have only ever read one webnovel, and that is the famous Worm by wildbow. There is a sequel, Ward, which I hope to read eventually after I am done with my huge pile of physical unread books, aha. "Worm" is finished for sure and I think, by now "Ward" is finished, too. When I first found the universe, "Ward" was still in progress.
