In response to Orochimaru's solemn invitation, Uchiha Yuu merely shook his head and declined.
"Sensei, immortality isn't as wonderful as you think. In this world, the boundary between life and death is very blurred. Experimental body-snatching isn't the only way."
Uchiha Yuu casually revealed a piece of information that slightly surprised Orochimaru. Curious about what ability could allow someone to live forever, Orochimaru asked expectantly:
"Does such an ability exist in the Shinobi World right now?"
Uchiha Yuu could sense the urgency in his heart. It was because he understood the fragility of life that he studied ways to protect his own life and keep living. This was Orochimaru's next goal. He would keep experimenting for that goal until he succeeded!
"Impure World Reincarnation!"
Uchiha Yuu named a jutsu with which Orochimaru was not unfamiliar. He had encountered this jutsu before, but had never conducted any research into it.
It was a forbidden technique created by Tobirama, the Second Hokage, capable of summoning the dead back into the world. However, the jutsu itself had serious drawbacks. Orochimaru had only given it a superficial look at the time. It was vastly different from the immortal resurrection he had imagined, so he had not pursued it further.
"Sensei can build upon the Second Hokage's research and begin a new round of development. The terrifying potential of Impure World Reincarnation goes far beyond its current effects. After all, Sensei Orochimaru's abilities alone are limited. If you summon scientists you deem worthwhile and have them conduct research tirelessly, it will surely speed up the process."
He felt that using jutsu to resurrect powerful people was the wrong path. Those brought back would not be of much use, aside from continuing to fight in wars and bringing endless slaughter.
That single sentence enlightened Orochimaru. As
