The first time I read this, it was ok. Maybe because I can't remember when but like 3 years ago and then recently I reread it again and I was like can't sleep without finishing it coz the story's so good!!! I was hooked with every chapter ending that I have to read what's next. Didn't prepare for the biblio taikai coz I reread the whole thing. But it was worth it. If I can recommend manhwas then this is certainly amongst the best.
