One of the best book i have ever read. Has Solid world background, and author knows what he is doing. So far in story(1357), there is little to no unreasonable power ups.Though story takes time to develop more but it is amazing.Almost all characters have some purpose, almost no nonsense character.MC is low key and no harem(maybe romance at late)MC doesn't become OP from start but put lot of efforts for it.For people wanting Magic, yup there is but not from start. Magic intro was a good arc.Almost all Arcs are good.Long Story, worth to read.
