is one piece episode 746 filler?

On the Yonta Maria, the Straw Hat Grand Fleet's party continues. Law stands abovedeck looking at the sea, and Robin approaches him and asks what he will do next.

However, Law leaves and tells her to leave him alone. On Dressrosa, CP0 agents Rob Lucci and Spandam receive a report from Kaku that the Underworld weapons left on Dressrosa were all stolen, most likely by the Revolutionary Army.

Lucci then orders that they leave. Meanwhile, the citizens begin celebrating a new beginning for the island as Viola and Gatz dance for them.
