Review Detail of Negi95 in Naruto: The teacher system

I read until Chapter 115: S2 Ch 23 (Ch 111). Up till whe the MC starts to travel the book is pretty good, with just a few problems here and there (nothig too bad, really). As he decides to travel, the story start to get worse, but still pretty decent. Than you arrive at chapter 114/115 and are hit by a tsunami of BS the immensity of which is immeasurable. Imho the only way to not drop off at that point is if you are not that interested and unknowingly skip all (or almost all) the BS, and don't notice. It pains me to give a bad review to a book I was enjoying, but I would rather have not read more than 100 chapter, only to be so disappointed I coulden't continue reading, and hope this review spares someone the same experience... and maybe helps the author to write better in the future
