Smooth Training (順調なる修業, Junchōnaru Shugyō) is chapter 318 of the Naruto manga.
Deidara and Tobi defeated the Three-Tails and started towing it to the nearest Akatsuki base. Tobi insisted that he did all the work, which Deidara disagreed with. Tobi fell asleep while he's arguing his case, prompting Deidara to attack him. In Konoha, Naruto was finally able to cut a leaf in two, completing the first phase of his Wind Release training. For the second step, Naruto must use wind to halt the flow of a waterfall that Yamato created. Meanwhile, Tsunade instructs the Nijū Shōtai to capture or eliminate Akatsuki members Hidan and Kakuzu before they leave the Land of Fire. When Asuma hears how they killed Chiriku, he decides to take his team to the Fire Temple.
