Half a month had passed since Shang Yu was captured by Jiraiya. During that time, the Sand Shinobi had sent no one to harass Konoha Camp.
Even so, Konoha had not let down its guard. The Hyuga Clan and Aburame Clan ninja kept a constant watch on the Sand Shinobi's movements.
For the past half month, Yamanaka Tohru had been teaching Medical Ninja while learning Wind Style Ninjutsu from Jiraiya.
Just as Jiraiya had said, Tohru had a good aptitude for Wind Style. In half a month, he had learned four C-rank jutsu, three B-rank jutsu, and one A-rank jutsu.
Tohru was learning Wind Style to lay the groundwork for learning the Rasenshuriken later. He and Namikaze Minato had developed the jutsu together, so he had the right to use it.
Whenever Tohru thought of how the jutsu had performed when Minato tested it in the Forest of Death, he couldn't help envying him. Until now, he had spent all his time on Ice Release: first solving the problem of its enormous Chakra consumption, and then learning Water Release Ninjutsu.
Tohru knew very well that Ice Release was his greatest asset for making a place for himself in the world of Naruto. Until he had solved its problems, no matter how powerful the Rasenshuriken was, he couldn't afford to spend time learning it, no matter how much he wanted to.
Now that he had solved the problems with Ice Release, and Sunagakure had made no moves lately, Tohru didn't want to waste this time.
At the Battle of Hizashi Bridge, saving Obito could mean facing Madara Uchiha directly. Even if Madara was in his twilight years, Tohru would need at least the strength of a Kage to stand against him.
