I'm speechless. The truth is very cool, but also concerning. According to my experience, most series that has too serious theme and such large scale of world setting tends to go bad because the author can not handle the big plot, especially when the powerscale and plot is consistent instead of some isekai/fantasy bs. Most of the time, the series end with either unsatisfactory end or controversy. The author has done awesome job so far, but I hope he can keep it up or at least find a good point to wrap the series.
