In any case, wanna see picture because Zoro coughing blood and having blood meaning nothing for Zoro.
He got heavily cut by Killer, 1 day after was fine.
Zoro tank all the Luffy pain + his dmg with Kuma, and survive. Few days after he was fine.
Zoro got slash by Mihawk, 1 day after was fine
Zoro got cut multiple time in vital spot by Mister 1. Few hours and he was fine.
Zoro is Zoro (other characters would have died, never recover back).
So I wanna see picture to judge the entity of the dmg before theorizing what ll come next.
