is one piece episode 801 filler?

Luffy grows tired as he continues destroying Cracker's endless numbers of Biscuit Soldiers. Cracker taunts Luffy over this, and Luffy declares he will simply destroy the Biscuit Soldiers faster than Cracker can create them.

Unleashing Double Culverin, he rapidly destroys the Biscuit Soldiers one by one in a continuous motion, but no matter how fast he goes, Cracker is at the ready with more Biscuit Soldiers. After this fails, Luffy decides to try taking out all the Soldiers in a single blow, so he flies into the air and blows into his arm, activating King Kong Gun.
