look not gona lie, 1 admiral said he wouldnt have come to wano if Kaido is still the ruler in Wano.
Remember how prime Whitebeard didn't invade Wano when Kaido was ruling?
And Greenbull did not talk about the Admirals alone, he said that Kaido's presence kept ALL enemies out of Wano, including other Emperors. It simply takes too much resources to invade Wano and the Navy cannot put their all into this since they have to keep Order in the entire World. And they were doing business with Kaido anyway through Joker.
kaido stated that only the strongest can use advcoc
Yes.
Shanks not fighint but just relising advcoc with his blade overpower an admiral will cuz just a few minutes before he clearly stated that he is after joy boy/luffy. Shanks coc and he is gone.
He released his CoC and threatened Greenbull which made Greenbull retreat, that's pretty much what he did. And even then, it was Shanks & the Red Hair Pirates in total which is not what Greenbull signed up for. But yes, I won't debate against Shanks > GB.
Now tell me if that not a L for navy boys?
How is possibly weakest Admiral needing possibly the Strongest Crew in the World & Shanks to threaten him for him to back off an L for Navy Boys?
