After weighing the pros and cons, Obito said in a deep voice, "Fine, I can agree to your terms! However, we've received news that the Ninja Village Alliance is currently mobilizing on a large scale. So, before we confirm 'B's whereabouts and formulate a plan to encircle and suppress her, you must obey our arrangements!"
For the current Obito, the obstacles weren't just the Five Great Ninja Villages, but also that mysterious 'A', and even Nagato, who was currently his ally.
He could use Nagato to deal with the Five Great Ninja Villages and 'A' now, but once all nine Tailed Beasts were collected and they entered the phase of resurrecting the Ten-Tails, the divergence between him and Nagato would instantly erupt.
Because there was only one spot for the Ten-Tails Jinchuriki!
And in order to confront the Ninja Village Alliance, as well as 'A's group—that mysterious force also calling themselves the Akatsuki—he had no choice but to assist Nagato with all his might, which caused Nagato's strength to increasingly surpass his control.
The current Nagato not only possessed the Rinnegan, hailed as the 'Eyes of the Sage', but also used the Rinnegan's power to control the Two-Tails, Four-Tails, Five-Tails, Six-Tails, and Seven-Tails Jinchuriki—five Jinchuriki possessing terrifying amounts of chakra.
The massive amount of chakra, in turn, strengthened Nagato's control over the Rinnegan.
The most obvious change was that Nagato, who was previously overwhelmed by the 'Gedo Statue' and the Rinnegan, emaciated to the bone, and unable to heal even a leg injury caused by a mere explosive tag, had now gradually recovered to a normal body, freeing himself from disability.
Although Nagato kept this matter a secret.
But with Zetsu's intelligence, Obito still found out.
Against a disabled Nagato, Obito was confident in launching a surprise attack. But if Nagato recovered his health and his strength surpassed the past, reaching an unprecedented peak, then with his current strength, wanting to deal with Nagato and seize the resurrected 'Ten-Tails' and the Rinnegan was obviously somewhat beyond his reach.
So from his personal standpoint, cooperating with Orochimaru and using the 'Impure World Reincarnation' Madara Uchiha to counter the increasingly powerful Nagato might not be a bad way to break the deadlock!
"Here's to a pleasant cooperation!"
Orochimaru seemed certain Obito would compromise, smiling as he released the 'Summoning Jutsu'.
Watching Madara Uchiha's 'Impure World Reincarnation body' disappear, Obito secretly breathed a sigh of relief.
The pressure this man gave him was simply too great. Even though he was dead, facing this man still made him somewhat uneasy.
Gathering his thoughts, Obito said to Orochimaru, "Regarding the latest movements of the Ninja Village Alliance, do you have any news?"
Orochimaru smiled, "The Five Kage have currently gathered in the Hidden Leaf and started a new round of Five Kage Summit. Consider this piece of intelligence a bonus for our cooperation this time!"
Obito frowned slightly, "A new round of Five Kage Summit..."
Every time a Five Kage Summit was initiated, it meant something big was about to happen in the ninja world. And this time, the Five Great Ninja Villages kept the news so tight, indicating the problem might be more serious than imagined.
After discussing some cooperation details, Orochimaru turned and left.
After Orochimaru left, Zetsu emerged from the ground and said in a surprised tone, "How did Orochimaru summon him with 'Impure World Reincarnation'?!"
Obito complained, "That's a question for you. Didn't you handle his corpse personally?"
Zetsu shrugged helplessly, "Although I heard Orochimaru has been digging graves everywhere recently, I didn't expect him to actually find his corpse!"
"Hmph!"
Obito snorted.
In his perception, Black Zetsu was Madara Uchiha's will, so he didn't want to show other emotions on this matter.
Zetsu asked, "What do we do now?"
Obito said, "Now we can only take it one step at a time! Madara won't tolerate being revived in this form. So it's fine that Orochimaru summoned him with 'Impure World Reincarnation'. At least he can personally assist us in controlling Nagato, making Nagato use 'Rinne Tensei no Jutsu' to truly resurrect him!"
Zetsu seemed to just realize and laughed, "Hehe, it seems Orochimaru unexpectedly did us a big favor!"
Watching Zetsu chuckling, Obito cursed inwardly, "Idiot!"
In front of Zetsu, he had always disguised himself as a loyal disciple of Madara Uchiha. But only he knew that whether it was Madara Uchiha or Nagato, they were all stepping stones for him. He wanted to use his own method to bring true eternal peace to the ninja world!
However, he didn't notice the mockery hidden in Zetsu's smile.
Undoubtedly.
It was precisely Zetsu's silent guidance from the shadows that allowed Orochimaru to find Madara Uchiha's corpse. Otherwise, even if Orochimaru had three heads and six arms, he couldn't have found Madara Uchiha's corpse so easily.
As for why he did this, it was obviously because he had already seen through Obito's mind, knowing that Obito had long harbored thoughts of betraying Madara Uchiha.
And in Black Zetsu's plan, Madara Uchiha, as the first person to fuse the chakras of Indra Ōtsutsuki and Asura Ōtsutsuki and awaken the Rinnegan, was the best candidate for the Ten-Tails Jinchuriki and the best candidate to cast the 'Infinite Tsukuyomi'.
As for others, be it Nagato or Obito, although one possessed the Uzumaki clan bloodline and the other possessed the Uchiha clan bloodline, tracing back, both could be traced to his mother Kaguya Ōtsutsuki, but after all, they were bloodlines after a thousand years of reproduction.
Moreover, the two of them were not reincarnations of Indra Ōtsutsuki or Asura Ōtsutsuki. Just bearing the Rinnegan was already very strenuous for them. Hoping they could smoothly become the Ten-Tails Jinchuriki was simply too risky.
That was why Black Zetsu had no choice but to guide Orochimaru to revive Madara Uchiha using 'Impure World Reincarnation'.
Of course, he also knew that doing so would definitely arouse Obito's suspicion. But he was sent by Madara Uchiha to monitor Obito in the first place, so even if Obito suspected, he wouldn't show it, nor would he think that he [Black Zetsu] was the mastermind behind everything, the culprit of the ninja world's thousand years of turmoil!
Both sides, harboring their own ulterior motives, tacitly stopped discussing the topic of Madara Uchiha.
Obito said, "The Ninja Village Alliance has started a new round of Five Kage Summit. It seems the final decisive battle is coming!"
Zetsu nodded, "It's good to act sooner. Nagato's control over the five Jinchuriki is getting stronger, and his chakra volume has skyrocketed. I'm worried if we delay any longer, we might not be able to deal with him!"
"Now is not the time to consider dealing with Nagato!" Pausing, Obito instructed, "Go notify Nagato and other members to prepare for the great battle! This time we will flatten the Five Great Ninja Villages and completely overturn the order of the ninja world!"
Saying this, he slowly spread his arms, "This decaying, filthy world has no necessity to continue existing!"
