It's a fantastic story. It has been a really long time since I have read more than 600 chapters of a novel. However, I just got tired of the author's tendency to drag things out. I thought he/she stopped at ch 200, but I was wrong. Although the author doesn't drag everything out. They do it for some things which tugged at my patience. Also the world background seems to be developing more than necessary, and I only see it getting worse. Too many new things are being added such that I stopped paying attention to it all together. Next is the, quite literally, random chapters. Initially, it was some radom set of characters in some random battle somewhere. Then it developed into what certain characters that you don't normally see, are doing. It's not necessary to have but it is not something I would consider bad either. It still added to thinning my patience. A certain event that pertained to the MC's level which spanned about 200? or more chapters significantly reduced my patience. It was resolved at a recent chapter of where I am but my patience was really running thin.It ran out after the author continued to drag out battles and expand world background every chance they get, introducing a large volume of information that I am not curious about. Well, I learnt a lesson from this. When a good story meets an author that likes to drag things out. It turns into a matter of patience rather than how good the story is.
