How was it not treated? He received a stab wound, and a serious one. They stopped the bleeding, bandaged it, maybe even sewed it up. And 1 and 2 is a fact.
Your scan shows that it's bandaged. And when she pulled on his arm, he bled again. In the next chapter, the blood is no longer on the bandages, so it has been bandaged again. You can't see it on your scan at the bottom, but it looks like that's where she's changing the bandages again.
about Zoro who must always be nerfed
When Sanji encountered Vergo, no one complained that he was injured, because it was "not more than an hour" after he was blown up and buried under the rubble in the cave. But when Zoro was unable to do anything to Kyoshiro, it was immediately noted that he was previously injured, he was without a sword, the weather was not suitable. And all this is normal, but you are not consistent. I'm not talking specifically about you, but about Zoro's fans. I treat both of them equally, by the way.
