Do you know what the best part is? You are fighting a losing war either way.
Mihawk's statement is a lie. As hard as finding OP is, it has already been achieved, at least 2 times, by Joyboy and Roger.
How many times has prime Mihawk been beaten? Never. One is an impossible dream, the other isn't.
So, despite needing plenty of things to find the treasure, it is doable. Mihawk cannot be beaten.
Time to board the Zoro/Mihawk supremacy train, Rudbir.
