When Orochimaru realized something had gone wrong, it was already too late to use Hashirama's cells to suppress Madara's actions.
Madara had successfully broken free from the control of the Impure World Reincarnation caster, becoming a special individual.
The Impure World Reincarnation Jutsu was not an inescapable technique. There were many ways to counter it, such as sealing, seizing control of the reincarnated person, or even forcibly breaking free if the reincarnated person's willpower was strong enough, allowing their soul to return to the underworld, and so on.
The simplest method—and also the most impossible one—was to learn the hand-seal sequence of the Impure World Reincarnation in advance, then undo the caster's control oneself.
Orochimaru did not believe any reincarnated person would know it, so he had not guarded against this possibility at all.
Aoba, meanwhile, believed that Madara had been able to undo the Impure World Reincarnation in the original story because Black Zetsu had witnessed Kabuto's demonstration and secretly told Madara, allowing him to break free.
This time, Orochimaru would not make such a low-level mistake. Madara should not have been given such an opportunity.
Thus, he had not paid much attention to it.
In any case, the impact would not be great.
Perhaps Madara would still be needed as a tool for a subsequent Death-Seeking Mission.
But judging by the current situation, Madara might have been on guard from very early on, having already witnessed Tobirama's technique.
He had probably been worried that Tobirama, who had never gotten along with him, or Tobirama's descendants might reincarnate him after his death and use him for something.
Madara had never felt that there was anything wrong with viewing others with the greatest possible malice.
Now, that caution had finally come in handy.
