is bleach episode 140 filler?

In Karakura Town, Kisuke Urahara skids back through the air with a smoking wound on his shoulder away from Wonderweiss Margela, who holds his hand out after firing a Bala from it, and admits that he has never seen this technique before inquiring about what it is called. Suddenly, Urahara is blasted from behind by a Bala from Yammy Llargo, who laughs maniacally and explains that a Bala is a projectile of hardened Reiatsu that trades the power of a Cero for twenty times its speed.
