Guys someone here is smoking hard shit right...do you notice the line in the middle of the hole that is a tiny blade, how in this planet you can say that this hole is the size of Onigashima....are people that retarded? How in the world can you say that the rocks next to this hole are big mountains? are they also retarded? look the blade didnt become larger the blade extended to Wano. If you can see the blade base on the hole you can understand that the hole that you see on Wano is slightly bigger than what Yamato is watching.
Gosh people cant even read this manga. They smell hype and get an overdose
