The reconnaissance lasted several days, and Tobirama came away with a few unexpected discoveries.
Both the fragments of the Demonic Statue of the Outer Path and the samples from White Zetsu and the Fusion Experiment Subjects stirred Tobirama's keen interest in research, making him want to develop new forbidden techniques.
But when he looked at his crack-covered hands, Tobirama remembered his elder brother's warnings from when he was alive, as well as the fact that he now possessed a reanimated body.
Impure World Reincarnation did summon the souls of the dead from the Pure Land, but it also disrupted the order of the living.
And as the creator of this forbidden technique, he had tasted its bitter consequences himself, becoming a target of reanimation.
Dismissing the distracting thoughts, Tobirama arrived at the Tower in the central district.
More residual rinnegan chakra lingered here, but there were also more guards, including some Hyuga with the Byakugan. Even he had to proceed cautiously.
Despite a patient search, Tobirama found very little.
As the place where the Akatsuki Leader had once hidden, anything of value had long since been sent to the Five Great Shinobi Villages for research.
Though the Akatsuki was a heinous organization, its technology was not.
Having witnessed the Chimera Technique, the Five Kage had all independently decided to continue refining this dangerous formula.
The Five Kage, who had temporarily formed an alliance, could hardly be naive enough to believe it would last forever. The results of their research into new technology would determine their future influence.
Ultimately, the Five Great Shinobi Villages were military organizations, and their arms race would continue indefinitely.
Soon, Tobirama reached the Rooftop atop the Tower. The view was excellent, offering an unobstructed panorama of all Amegakure. It could well be called Amegakure's Kage Rock.
