None. Shippuuden pick up the manga storyline. The rest of naruto is filler, except maybe the last 5 eps.
The second half of 220 has important canon material in it. There are also some canon scenes around 137ish wish Sakura in the hospital talking to Naruto about being useless and then asking Tsunade to train her. Everything else from 136-220 is filler.
thats sucks. Thanks for the heads up. I hate wasting time on useless episodes.
You mean the episode between 136-220?? So what ep do suggest I start on then?
