Aokiji landed on Whickey Peak, actually sweating becuase of the long bike ride around the Red Line.
"Maybe...I should've... taken a break from biking..."
Later, the bounty hunters heard that one of the admirals of the marines was here, and decided to take the inititave to 'welcome' the guy to Whiskey Peak. However, when they got there, they found that Aokiji was asleep. So instead of partying which might wake him up, they decided to go ahead and kill him now. They fired the gun at him, which went straight through Aokiji while the parts of his body around it turned to ice. They tried firing several more bullets, but with no success. So finally they decided to just take him hostage, which might just have worked had Aokiji not started dreaming a nightmare that occasionally popped up.
"Saulo, I'm sorry, but I have to initiate the Buster Call!" In his sleep, he stuck out his hand and started completely freezing the bounty hunters in their tracks, and were gradually losing consciousness. Then Aokiji resolved the matter.
"Oh yeah, Ohara's still there." Aokiji, for the time being, continued sleeping.
