Too many chapter but too slow story

This is a good novel. The story is good and interesting. If I was asked whether I would recommended this story or not, then the answer is I will recommend it.
What I don't like is the story progress is too slow, monotone, and it goes forward and then backward again. The author is forcing the story to extend to much, resulting in too many useless chapter, add to that the forward and backward style making it more frustating to read. At the end, I choose to skip lots of chapter in the middle of a story arc, for example holy city arc. And guess what? I still can follow the story lol. To author, I hope you can fix this.
Bottom line, I still like this work. So thanks a lot.
