Unsurprisingly, Orochimaru was very interested in this ninjutsu and had dug up quite a few graves to study it. He had even specifically asked Anyo whether he wanted White Fang brought back through Impure World Reincarnation once the research succeeded.
Anyo naturally shook his head and refused. This ninjutsu was actually deeply disrespectful to the dead. If White Fang knew he had been brought back through Impure World Reincarnation, the first thing he would probably do was draw his blade and cut down his unworthy disciple, Anyo. Still, this reminded Anyo that this was not his previous world. Death did not mean resurrection was impossible here.
The key to resurrection lay in the Rinnegan. Konan had already graduated from the Ninja Academy. It was time to find an opportunity to send her back.

He had named this new technique Living
