That's probably because of it's odd vibe. The 10 commandments were all by all done it very easily and rapidly, which doesn't make much sense. Unless there's still a plot twist, but so far that hasn't been the case.
It felt to me like the mangaka is trying to wrap each arc up every 100 chapters for the anime, so he had to have the 10 commandments defeated really quickly to end by 200. Chapter 198,99,00 will probably be building up the next next arc or war vs The goddess clan. We're getting more and more hints, even in this chapter, they mentioned a grand battle.
