But what does that have to do with him being invincible in flame mode?
It he was blocking in flame off mode then you would be right.
However, here, he wad blocking in flame on mode which you say is invincible.
It doesn't.
Because King was blocking/dodging/engaging in Cqc even in flame mode before CoC.
The point is CoC changed virtually nothing in that fight regarding how to get through King, it only helped Zoro to take him down before Enma would kill him.
I am quite sure he made that statement right after he healed from bird dance and before he used the second flame dragon.
I'm on PC now so here are the scans.
After this, Bird Dance happens.
This sentence has to do with CoC, yes.
It has nothing to do with Lunarian ability.
King was off the island at that time so he would not notice and get was covered by the flame dragon
Why not?
King wasn't in flame mode the entire page.
Bro, no offense, but that's genuinely dumb. Why would he be scared of losing when he knows he can't be hurt when he has flames on? It has no correlation with Zoro learning his secret because he should only be scared of Zoro when his flames are off.
Besides, it makes no sense for Zoro to say, "I thought my attacks did nothing to you," when they both know King can be hurt when his flames are off. This reason is completely irrational.
The point is Zoro now figured out how to get through to King, which is by attacking when the flames drop.
"I thought my attacks did nothing to you" But now they do, hence why that statement and taunt, which comes right after King says "You've figured out the rules of my body."
King was afraid because he felt he was about to lose, not because Zoro can get through Flame Mode.
We know from Zoro's own words that it's Invincible.
