After waking up his mentor with the happy news, Naruto hurries to demonstrate his progress. Using the new method, Naruto managed to burst the balloon in front of Jiraiya’s eyes, which means he is ready for the second stage. In addition, he reports that he came up with this method by watching a cat. Jiraiya and Naruto head to the training area, but instead of the usual activity, the boy once again gets his hands on a ball, this time a rubber one. According to the sannin, it’s a hundred times harder to burst such a ball, so it’s necessary to increase the power of rotation. Naruto tries to apply the tried-and-true spinning method to the ball, but it doesn’t work. He asks his mentor for advice, but he says Naruto must come up with a solution on his own, and leaves him. Naruto practices tirelessly every day. Three weeks pass like this. Eventually he decides to use the pain in his hands as an indicator of the amount of chakra released and, having accumulated enough, he blows a hole in the ball. Jiraiya witnesses this breakthrough, but Naruto is not happy with the result. However, the mentor is pleased with his student’s success and hands him an ice cream, praising the boy. Jiraiya assures him that Naruto has almost succeeded, so he prompts him with a small trick by drawing a small spiral on his palm.
