Looking at the now completely empty ruins, Ueno Kei shook his head slightly. Just moments ago, he had used a secret technique to ask the Great Elder whether they could use Spatial Lockdown to seal off this area and prevent Tobi from escaping.

The Book of Seals also contained their detailed explanations and notes on spatial ninjutsu. It was a little late to start learning now, but gaining a certain understanding and finding a way to counter spatial ninjutsu was still entirely possible for Ueno Kei.
