There was even less need to "trade a life for a life" as with the [Dragon Life Reincarnation Jutsu] and similar techniques.
[Resurrection of the Dead] was simply an ordinary resurrection technique with a routine expenditure.
The Sun Senjutsu Chakra Uchiha Minamoto expended using [Resurrection of the Dead] could recover on its own with nothing more than some sunlight.
It was no different from ordinary ninjutsu...
Moreover, within the [Limited Tsukuyomi] world.
After using [Resurrection of the Dead] to revive Hashirama Senju and the other three in succession, Uchiha Minamoto discovered another "hidden effect" of [Resurrection of the Dead].
Any ninja revived through [Resurrection of the Dead] would return directly to the strength of his prime!
The quality of the reanimated body had no bearing on this.
Whether it was the two Senju brothers, revived using ordinary death-row prisoners as sacrifices, or Minato Namikaze, revived using a White Zetsu as a sacrifice.
After Uchiha Minamoto revived them with [Resurrection of the Dead], all three Hokage returned to their best condition in life.
Tobirama Senju in the [Limited Tsukuyomi] world had even said outright-
"It feels like every cell in my body has regained its vitality."
Hashirama Senju had a similar opinion, though his words were not as straightforward as his younger brother's-
"I feel like a great tree that's had its fill of sunlight..."
Hmm...
That was just how plant people were...
Uchiha Minamoto was quite satisfied with the actual effects of [Resurrection of the Dead].
This was his ideal resurrection technique!
Previously, Uchiha Minamoto had planned to trade White Zetsu lives for the lives of the Hokage.
The procedure would roughly go like this-first, use a White Zetsu as a sacrifice to revive the target with [Impure World Reincarnation]; then find another White Zetsu and use [Dragon Life Reincarnation]
