This is indeed the shortest arc in the New World, not including the Sabaody reunion arc. This arc is quite a breather arc after that long ass Dressrosa where Oda adds too many plotline and a dragged out battle.

Here we have an straightforward arc with no dragged out battles, no deep back stories, we have not know about Zunisha's back story yet and not very much was going on. Plus there's no bad Minks. However the story has entered a resolving stage and the story is not going to be dragged on very long.
