Obito Uchiha thought, So they really did reincarnate Hashirama Senju.
With that thought, he summoned a White Zetsu, then turned to Kabuto Yakushi and asked, "Would this thing qualify as a sacrifice?"
At Obito Uchiha's question, Kabuto Yakushi stepped forward, green chakra glowing around his right hand, and pressed it against the White Zetsu.
After a while, Kabuto Yakushi looked at Obito Uchiha and said, "This was cultivated from degraded Hashirama cells. As a sacrifice, it's merely adequate, not perfect."
"What's the difference between adequate and perfect?" Obito Uchiha asked.
Kabuto Yakushi answered, "An adequate sacrifice may qualify, but it won't allow a reincarnated body to fully exercise the strength it possessed in life. Some exceptionally powerful people can also break free of the Impure World Reincarnation Jutsu's control. It's best not to use this kind of sacrifice to reincarnate those two shinobi who defy all standards.
"Only a perfect sacrifice allows a reincarnated body to fully exercise its strength from life. Reincarnating a shinobi with a perfect sacrifice not only restores their full strength, but, more importantly, greatly improves your control over their reincarnated body."
"Do you still have any clones of Hashirama Senju?" Obito Uchiha asked.
Kabuto Yakushi shook his head. "Only Lord Orochimaru has clones of Hashirama Senju. I don't have anything like that."
"Do you know where Orochimaru is?" Obito Uchiha asked again.
Since Kabuto Yakushi had none, he would have to find a way to get one from Orochimaru.
Kabuto Yakushi shook his head again. "I don't know where Lord Orochimaru is either. Since we completed the Impure World Reincarnation Jutsu, Lord Orochimaru and I have only been able to communicate through White Snake."
This is a pain... There's no time to wait for a Hashirama Senju clone... Obito Uchiha was irritated.
*Wait, what if
