What crack, lol.

Only Ainz knows about the power of that sword, and he just said it can "hurt" him, which means theoretically it can "kill" him. That's like saying a spoon can kill me, if I like sit there and let it dig into my eye or something. Not gonna happen.

Time stop can be easily countered from Ainz's perspective. Pretty sure the humans don't even know what time stop is, much less how to counter it. The two who saw it didn't even know what happened, so yeah, useless duel.

Just stop being idiots and get on Ainz's good side. I mean, why the fuck not? They serve a king for a stupider reason than bowing to absolute power (i.e. tradition).

The warrior dood should've just asked Ainz to stop pursuing the human army in exchange for his service. Then Momon wouldn't even need to do the fake turncoat thing because warrior dood can do it in his stead.
