That's the light novel. A single page in light novels often consist of an entire "chapter". So 800 chapters could easily be the equivalent to like 30 actual chapters. In terms of manga, web comics, a 800 chapter web novel could be like 50 chapters.
I saw someone put a link to the rest of the written story and it has almost 800 chapters. I'm not sure if the drawn version will be but just wanted to let other readers know it's probably not ending soon.
