is one piece episode 71 filler?

As Nami and Usopp see someone gigantic approximating the Going Merry through breaking trees across the forest, they start crying. A giant comes out and asks Nami and Usopp for alcohol.

Nami respond that the only alcohol they have is for cooking and disinfection. The giant screams in pain because he just got bitten by a T. rex from the back.

He chops the T. rex head and introduces himself as Brogy, claiming to be the strongest warrior of Elbaph. He also calls Nami and Usopp as guests but, frightened, the two play dead.

Elsewhere, Luffy and Vivi are exploring.
