is one piece episode 814 filler?

Pedro continues his assault through the corridors of the Whole Cake Chateau, slicing through guards before they can raise their weapons in defense. His sheer speed blows soldiers away, and he uses explosives to take out multiple opponents at once.

As his rampage continues, Tamago and Smoothie race to corner him as they keep tabs on his location. However, Tamago wonders about Pedro trying to steal the Poneglyphs and then realizes that Brook had evaded their security just like Pedro did.

Smoothie then goes back to the Room of Treasure, but as this is happening Brook is already at the entrance.
