Sister's Bride
Ugh. "Everyone except our glorious celestial empire are a bunch of barbarians who wantonly kill their citizens for benefits! Only we treat Nightmares seriously!" That's such a blatant propogandist caricature of international politics that I can't take it seriously. Hopefully the author isn't actually this bad at world building.
This particular complaint isn't about the MC, it's about the ridiculousness of such a self-righteous stance from a country that feeds death row prisoners to a box. The MC is actually fairly down to earth about all this stuff. Side note, having read quite a bit of this after my comment, I can say that the author is in fact definitely NOT that bad at worldbuilding, but I still think not!china's decision on how to deal with these nightmares is incredibly dumb.
Klaudius:But isn't the MC trying to open up (at least this one) Nightmare dungeons to the public? Doesn't that mean the MC want to make "celestial empire" more like other countries?
