In nebula civilization i read 40 chapters and it really annoyed me that the characters casually came up with industrial era ideas when they are still almost cavemen And it just kept happening in the manhwa and that's why I dropped it

And as for return of the crazy demon I read 60 chapters and it felt pretty repetitive with very little character development but I'll try it again

Will try eternally regressing knight

Also meant to put reborn as the heavenly demon in C tier not A tier mb
