maybe someone here can answer my geographie questions before Oda, but if the world is divided in 4 by the grand line and red line, then how do ships go from one ocean to the other, there's a opening in the red line or something? And the only way to get out of the grand line is the calm belt? Why haven't anyone tried to get to laftel by entering the calm belt at the closest point to it?
