Beneath the tranquil depths of the Grand Line.
Inside the submarine of Wapol, king of Drum Island.
After Franky's emergency modifications, the submarine had gained upgrades to its space, performance, and waterproofing.

It might have looked a little shabby, but a lineup consisting of one Shichibukai and two Logia Devil Fruit users was already an unmatched luxury in the world.
Go ask whether the Celestial Dragons had Logia Devil Fruit users serving as bodyguards?!
The waters below were far from smooth sailing and peaceful. All kinds of sea beasts lurked beneath the surface, more than willing to find out whether this iron shell tasted good.

And this sort of danger was difficult to resist.
Other than Conqueror's Haki, among the entire Logia Devil Fruit lineup, only the Ice-Ice Fruit, the Rumble-Rumble Fruit, and the Snow-Snow Fruit could affect those
