Okay but there’s no visible indicators of the shit you are saying in this arc…
Zoro is just doing whatever he always does.
if Oda wanted Zoro to have a visible change in his power level he’d have him do KoH the way Sanji is using Ifrit or Luffy is mixing gears now… but he doesn’t…
If you put this panel next to a fishman island Zoro panel , you VISIBLY couldn’t tell a difference
There isn’t tbh
At the same time if zoro mastered enma to the point he can casually release that amount of haki there wouldn’t be a visual indication. The green flames indicating he’s using an overwhelming amount of haki. Mastering it means no green flames
Did he master it yet? Idk but seeing how much luffy, sanji, and even usopp have grown it wouldn’t be surprising
Zoro is stronger than he was in fmi…
You don’t need to be a scientist to know that
