Because Minato-sensei's son was just too persuasive, not only did Nagato completely switch sides, but he also used the Rinnegan to resurrect everyone who had died.
Obito Uchiha's first reaction was relief—Kakashi in this world must have come back to life too. But his second thought was: Holy shit, did I kill Danzō Shimura for nothing?! If only he'd known, he wouldn't have stopped at just gouging out Shisui's eyes—he should have ripped out every single eye on that arm!!
Then, hearing Katsuyu relay the message, he learned that the First Hokage, Second Hokage, Fourth Hokage, Jiraiya, and Yahiko had all been resurrected.
The adult Obito Uchiha from another world wore an expression of utter speechlessness. If only I'd known to have the Second Hokage take on more responsibilities—the more, the better! I should've resurrected everyone using the Edo Tensei Resurrection technique!
But it was too late to say anything now. Seeing Nagato's exhausted state, Obito Uchiha couldn't wait any longer.
Nagato said, "My mission ends here. Naruto, perhaps you truly can bring peace to this ninja world."
"No." The adult Obito suddenly spoke up. "Your mission isn't over yet, Nagato."
Konan stood in front of Nagato, prepared for both offense and defense. "What more do you want?!"
Adult Obito tossed several White Zetsu to Nagato. "They can replenish your chakra. I have one more task for you."
"What is it?" Nagato, unlike Konan, wasn't impulsive. He asked calmly. He could sense it. Though this masked man's chakra felt like Madara's, it also carried a faint trace reminiscent of Naruto's. If Naruto Uzumaki's chakra was like a forest after rain, then the masked man's chakra felt more like the damp earth beneath that forest.
Moreover, if he could find a reason to negotiate with this man, the chances of Konan and Yahiko remaining unaffected in the future would increase.
"If it's still that plan to gather all the Tailed Beasts, then forget it. I've already decided to stake everything on Naruto from here on out."
"Rest assured, it's not that plan," the Adult Obito replied. "That plan was a deception. Both you and I, even the real Madara Uchiha, were deceived."
Naruto listened, somewhat baffled, while Nagato and Konan's eyes suddenly widened.
The Adult Obito urged Nagato to restore his chakra. "The one who twisted the Rikudō Sennin's ninshū into this current state of relentless conflict among ninja…"
"It was Black Zetsu."
With that, Obito Uchiha from the mission scroll world ejected his counterpart from this world out of the space. This maneuver left Konan, Nagato, and Naruto utterly speechless.
"Why the hell are there two masked guys?!" Naruto stood dumbfounded.
The masked man surveyed Nagato, Konan, and Naruto Uzumaki, his expression slightly off.
"What's your game?" Facing his counterpart from another world, the masked man's low-pressure aura never wavered.
Adult Obito still ignored him, instead turning to Nagato. "Black Zetsu is currently within his Kamui's Dimension. I'll signal him shortly. The moment he releases Black Zetsu, you must immediately seal him away with Chibaku Tensei—to a place where no one will ever be able to reach him."
"A place where no one will ever be able to reach him?" Nagato frowned. "You truly want me to emulate the Sage of Six Paths?"
The masked man, Obito, didn't understand what his counterpart from another world was referring to. He knew the legend of the Rikudō Sennin, but why did sealing Black Zetsu require such an elaborate setup?
And what about that earlier remark—that the Moon's Eye was a deception? Had Madara Uchiha been deceived by Black Zetsu too?
The masked man's expression turned stony. "Must I remind you that Black Zetsu embodies Madara Uchiha's will?" At this point, concealing these truths from Nagato and the others held no meaning.
Adult Obito glanced at him. "Based on the information we know, Black Zetsu might be the Rikudō Sennin's youngest brother, while Madara Uchiha is the reincarnation of the Sennin's eldest son—who knows how many generations ago. They're generations apart. How could Black Zetsu possibly be Madara Uchiha's will?"
Seeing Nagato, Konan, Naruto Uzumaki, and the 'Masked Man' staring at him with expressions that screamed 'Are you kidding me?', Adult Obito sighed and explained once more.
"You know that the moon was created by the Rikudō Sennin, right? He used Chibaku Tensei. The person he sealed was his own biological mother. Black Zetsu might be something left behind by that woman. All this Infinite Tsukuyomi and Eye of the Moon Plan stuff is just a scam Black Zetsu concocted to find someone to help him revive Kaguya Ōtsutsuki."
"We recently obtained intelligence that Sasuke Uchiha and Madara Uchiha are reincarnations of the Rikudō Sennin's eldest son. Correspondingly, Naruto Uzumaki and Hashirama Senju are reincarnations of his second son."
"Don't look at me like I'm making this up. Your world isn't mine—I have no reason to waste time on you. If you don't believe me..." He turned to Naruto Uzumaki, "You can ask the Nine-Tails within you. Much of the intelligence we possess now, aside from some odd mission rewards, comes directly from the Nine-Tails and the Three-Tails."
"The Nine-Tails?!!"
"The Three-Tails?!!"
These exclamations came from Naruto Uzumaki and the masked man respectively.
It wasn't surprising that Naruto Uzumaki was shocked that the Nine-Tails knew about this.
As for the masked man... Upon hearing the name Three-Tails, his heart instinctively skipped a beat. It felt as though pressing further might reveal something that would shatter his understanding.
Meanwhile, in the scroll world, Adult Obito stared at the 'Masked Man' for a moment, ultimately choosing not to reveal the possibility of the Kannabi Bridge parallel world. In some parallel reality, there existed such an enviable, jealousy-inducing version of himself.
"Alright, everything that needed to be said has been said. If we don't get moving, Konoha will be here soon."
Adult Obito looked at Nagato. "Use chakra freely for Chibaku Tensei later. Even if you die, it's fine."
Under Konan's fierce glare, Adult Obito continued, "If you die, implant the Rinnegan into his eyes."
He pointed at this world's Obito. "Have him use the Rinnegan to resurrect you."
Naruto Uzumaki was dumbfounded. "Is that really possible?! Did I hear that correctly? Are you saying those Rinnegan eyes can be implanted into anyone and still function?!"
"It probably won't work for just anyone," Adult Obito countered. "But since those eyes evolved from the Uchiha's Eternal Mangekyō Sharingan, and Nagato—a member of the Uzumaki clan—could use them, there's no reason I, as a Uchiha, couldn't."
He glanced at his counterpart in this world and Nagato. "Probably because the First Hokage was there, the casualties in Konoha weren't as bad as expected. I was ready to replace your eye on the spot and revive Nagato if bringing Konoha's people back had killed him."
The others froze! There was such a method?!
If that was true, this move would be a huge win! Resurrect Nagato to bring back tens of thousands, then have Obito Uchiha resurrect Nagato alone.
After much hesitation from Nagato, Konan, and this world's Obito Uchiha, they ultimately decided to trust the Adult Obito from the other world.
Once Nagato was prepared, the masked Obito released Black Zetsu from his Kamui's Dimension.
Black Zetsu had been pondering inside Kamui's Dimension for over an hour, yet no matter how hard he racked his brain, he couldn't fathom why Obito Uchiha had suddenly turned against him.
Released back into the open, his grating voice dripped with fury.
"What do you think you're doing?! You'd better explain yourself, Madara."
He put a heavy emphasis on the name "Madara," reminding Obito Uchiha of his true identity.
At the same time, a sense of danger washed over him. As he spoke, he was already preparing to use his unique ability to detach a portion of his body and hide it underground.
Unfortunately for him, his movements were already noticed by the Obito Uchiha behind him!
"Who are you calling… Madara?!"
Crack—
A chakra-infused black rod slammed into Black Zetsu, pinning him firmly in place!
Black Zetsu twisted his head painfully. "Who are you?!!"
When he saw another Obito Uchiha wearing an orange mask behind him, Black Zetsu was completely baffled by the situation.
Obito Uchiha knew well how cunning Black Zetsu was, especially his ability to deceive others and stir up confusion!
"Nagato!"
Nagato, who had been prepared for this moment, shouted, "Chibaku Tensei! Go!"
Black Zetsu, along with Obito, the chakra-infused black rod embedded in the ground, and that small section of earth, were all sealed away into the sky above.
Amid Black Zetsu's desperate curses, everything coalesced into a massive sphere.
Immediately after, Shinra Tensei propelled it upward with a forceful push.
Obito Uchiha muttered, "That's a good idea. It's like granting his wish."
Let it go up there and keep that Kaguya Ōtsutsuki company!
