This book had the potential to reach 1000 chapters . Too bad the author decided to rush things in the later half of the story. Even so, I would still recommend this book to others. My personal rating: 7.8/10
What confuses me is the numbering. Novelupdates says this has 691 chapters and though this is chapter 690 it also states it's chapter 681 and to be continued. So either there are duplicates, chapter numbering is off or there are chapters missing.
