"The Battle at the Valley of Clouds and Lightning!!" (雲雷峡の闘い!!, Unraikyō no Tatakai!!, Viz: The Battle at Storm Cloud Ravine!!) is chapter 410 of the original Naruto manga.
Summary[]
Naruto is worried by Gamakichi's claim that he must die, but Fukasaku assures him this is just a terrible analogy. To become one with nature, and thus master senjutsu, Naruto must learn to be perfectly still and take in natural energy. A special oil can help him with this, but it runs the risk of turning him first into a toad and then into a statue if he is not careful. Naruto decides to go through with it, determined to be just as great as Jiraiya. Meanwhile, Taka battles Killer B, the Eight-Tails' jinchūriki. When Suigetsu and Jūgo prove no match for him, Sasuke steps in.
