I just found out the this arc is only two more episodes long then it looks like it goes back to crappy fillers again.

This are the names for the next couple of episodes
Episode 172: "Despair, The Heart Which is Torn"
Episode 173: "Sea Battle, Released Power"
Episode 174: "No Waaaay! Celebrity Ninpou: Kinton Jutsu"
Episode 175: "Dig Here! Woof! Woof! Search for Buried Treasure"
