The problem is Zoro didn't yet say anything about that so I'm really doubtful over all of that.
If Zoro mentions it later,I will be conceding to you pretty fast.
Zoro doesn't it need to say it when the manga shows it
Ever since the manga introduced the minks
medicine everyone assumed it would fully recover Zoro. That's understanding at that time. We didn't know much about it and it was called an ultra regeneration medicine.
Now we've had a several chapters to see Zoro fight and the medicine doesn't seem to have fully healed him. Not nothing about it makes me believe it fully recovered his body. Medicine doesn't normally recover stamina and Zoro has been breathing heavy since the beginning of the battle. He normally doesn't breath that heavy that quickly. Zoro's body is still bruised up. If his body fully recovered those marks and injury would be gone.
This isn't about taking everything from King. He is incredibly powerful. More powerful than some wish to give him credit for.
