Alright, so I just finished reading the first three chapters and honestly, it's not even bad. It's actually quite well-written aside from a few strange formatting quirks which I simply assumed were stylistic choices. However, the density and format of the paragraphs are particularly chunky and one absolute CHONKER that stood out to me was this one:
This is a MASSIVE paragraph. A goliagraph, even. It also contains several sections of speech (grammatically, it's fine since it's the same person speaking) which would read much smoother if separated. It's important to keep in mind that most readers are either reading in class/at work/while shitting on their phones, so separating your paragraphs will help immensely.
This is something I've seen throughout the chapters I've read. Here's another example from the very start of chapter 4:
Usually, you don't want to start off with a massive block of text.
Outside of this, I can't really find much fault with the writing itself. It's certainly not a grammatical mess, and I don't see any weird shit that might turn readers off (though, one of the most popular books on this site has a pretty damn weird first chapter in my opinion). The dialogue isn't terrible, and there's really nothing wrong with the writing itself.
As for why I didn't keep reading? I felt I'd read enough to see that it wasn't your writing that was the problem. Other than that, I'm clearly not the target audience of this novel, so any story-centric criticisms from me wouldn't be useful or helpful to you at all. That said, the plot progression seems slightly slower than most readers would like (since they're used to fast-paced power progression novels), but that's the tradeoff for the lengthy descriptions you've got in each chapter.
