1. You have failed as expected to show me a panel where they acnowledge zoro and NOT the sword. let me ask you this,
what was the sword zoro cut kaido with? enma right?
HONESTLY did you even read the panels you yourself showed? Kaido comments "
ahh that hurts...I see that must be Odens sword" enma was the ONLY sword that hurt him in that attack and ALL of zoros swords were hardened.
2. No, stop reading 2 piece...Ryou is just what people in wano call all types of haki just like mantra in skypiea.
barrier ryou is just an advanced version of arnament and internal destruction is a step even higher. if it sucks out adv ryou from zoro isn't that just proving my point
3. Are you blind? do you not see that surprised mark right besides zoros face?
