Review Detail of John_Or in Shinobi From Hell

This novel is ok as at chapter 103, the world background was ok,the story is good. But... There is alot of problems with the writing quality, alot of errors with the writing plus the story lacks detail in a lot of ways either with the quests, classes, equipments and even the story plots. For instance how long did the tutorial last. MC made a comment to the new initiates dying of thirst in the early chapters but we never saw this happen. The quest for water was a total flop, the group went out once and that was it no further updates. Though I assume it was a failure but after that was another plot and then the end. In shot Author needs to develop story better - more details.
