Senju Nawaki hadn't gone to Hanamaki, but Takekama Senju, who was about his age and had kept a low profile for years, had.
Before long, Yanbai saw Kima Senju and his younger brother Takekama, who was practically like a son to him, carried back with serious injuries.
Yanbai was astonished. Only after asking what had happened did he learn the reason.
Hanamaki needed extensive construction work to follow Yanbai's plans. The prisoners of war had their chakra restricted, and even without those restrictions, they weren't strong enough to split a mountain in one shot with ninjutsu.
So the Land of Fire supplied explosives that even civilians could use.
Takekama Senju... The kid normally kept a low profile and didn't seem mischievous, but once he actually joined the construction effort, he turned into "Thousand-Hand Teemo," driving his teammates and the prisoners of war up the wall.
Construction had only just begun. First, they needed to blast a rocky mountain flat, then put up new buildings on the site.
That made blasting through the mountain the first step in construction.
Burying the demolition charges according to the plans was simple. Even at his young age, Takekama should have been able to handle it.
Unfortunately, Takekama Senju had such a terrible memory that he couldn't even remember where he'd buried the charges. He claimed he'd followed the plans, but who knew how he'd been reading them.
He hadn't planted any where they were needed, and he'd planted heaps where they weren't.
In the end, Kagami Uchiha, who supervised construction in Hanamaki, couldn't stand it anymore and sent both Kima and Takekama back.
Kima was a former Hokage. Rather than being injured in battle, he'd nearly been blown to death during city construction by demolition charges his own little brother had buried. If word
