We don't know, I'd imagine it requires stamina

Bruh y u have 2 do that vijey

It was already up y take it down

@Vijey221 bruh

I assume it's like walking, you won't get tired if you walk for a couple of minutes (if you aren't obese) but if you walk for many hours, you will indeed get pretty tired

Ya I imagine it's stamina too, similar to Law and his room.... How much they could utilize is just dependent on their competence.

I'd like to imagine when Akainu and Aoikiji fought they had tea breaks in between.

Yeah we don't know what happened during the ten days. I made a point in a post many months ago where akainu and aokiji could've fought for several hours and then planned the future out where akainu go on to be the fleet admiral, while aokiji go undercover in BB's. There are some suspicions along the way that makes me think they didn't just fight.
