Elsewhere, after Shiro subdued Shukaku, Orochimaru's experiment was also drawing to a close. With a casual gesture, he undid the Impure World Reincarnation on Chiyo and Ebizo, whose bodies were already badly damaged.
As Orochimaru thought things over, he moved to meet the Suna Ninja, preparing to coast through the decisive battle.
This experiment had still been very valuable to Orochimaru. After all, it was his first time using the improved Impure World Reincarnation, and his research into the original version had only been preliminary.
So in truth, all of this was still very immature.
Just as this attempt had shown, leaving aside the clumsy feeling of forcing control, Orochimaru estimated the original version was probably like this too.
The changes he currently knew of were twofold: the immortal body and the sacrifice.
The immortal body seemed difficult to restore because the body was materialized Chakra. Though it was still an immortal body, its recovery speed was far too slow.
Secondly, because the body being used was a Chakra-materialized one researched through the Tailed Beasts, the conditions for casting Impure World Reincarnation only required a large amount of Chakra and cellular tissue. The original living sacrifice was not strictly necessary.
But that had both pros and cons.
The benefit was that this made things much more convenient. After all, there was no need to find a suitable sacrifice, and the impact on strength was very small.
But the drawbacks were also obvious. First and foremost was the consumption problem: at present, a single casting required one stroke of a Command Spell!
That consumption was no small matter. The Dragon Vein's Chakra was not endless. After it had been organized, its natural daily recovery amounted to only two strokes.
Any more than that would damage the Dragon Vein's source. The Chakra
