Orochimaru stood there for a moment, the ghost of his laughter still fading, looking at Finn with the expression of a man who had just lost an argument he hadn't expected to lose.
Then he gave up on the Tsunade topic entirely.
His eyes dropped to the scroll Finn had set on the table earlier — the one with the Forbidden kanji stamped across its face. He picked it up.
"Let me see what exactly it is that you claimed would make me ecstatic," he said, with the tone of someone prepared to be mildly disappointed.
"You'll want to thank me when you finish reading it," Finn said, and went back to the notebook.
Orochimaru did not respond. He broke the seal and unrolled the scroll.
Four large characters. Shapeshifting Technique.
He raised an eyebrow. An interesting name, at minimum.
He read.
Three breaths passed. Then five. His eyes moved faster. His tongue slid out — slow, unconscious, the old reflex — and traced his lips once, then again.
"Interesting," he said quietly. Then, louder: "Very interesting."
He looked up from the scroll. Something had changed in his face — the cool, detached expression gone, replaced by the sharp-lit focus of a man who had just found the answer to a problem he'd been living with for years.
"The person who developed this technique," he said, "was a genuine genius. I would call them nothing less than enlightened."
He looked at Finn with something that was, for Orochimaru, remarkably close to warmth.
"I have to say it plainly — things have gone considerably better since I met you. I find that more true with every passing month."
He wasn't wrong, and he knew it. Before Finn, his Wood Release research had been completely stalled — the mechanism understood in theory, the practical path invisible. His immortality work had been caught in the wrong frame entirely, fixated on the body rather than the soul. He had never seriously pursued Sage Mode, had never seriously engaged with the Sharingan's deeper implications. The idea of acquiring a Rinnegan for study would have been pure fantasy.
After Finn, the Wood Release research had a living primer in the field, waiting to germinate. His approach to immortality had been rebuilt from the foundation upward, pointing now at the soul rather than the body. His Sage Mode research had found its footing. The Sharingan research, once he'd been pointed in that direction, had produced results neither he nor Sasori had anticipated. And the Rinnegan was now sitting in a sealed scroll two rooms away.
Every one of those developments traced back, in some direct or indirect way, to Rodriguez Finn.
And now this.
The Living Corpse Reincarnation technique had been Orochimaru's central research problem for years. He had worked his way to the edge of a solution — close enough to see the shape of what he needed, too far to reach it. The final hurdle had sat there, resistant, for longer than he was comfortable admitting.
The Shapeshifting Technique broke it open.
The two techniques shared structural DNA at a level that wasn't immediately obvious until you read both side by side. The way the Shapeshifting Technique handled the problem of consciousness projection into a constructed vessel — the mechanism by which it maintained the original self's coherence while the form changed — that was precisely the conceptual gap Orochimaru had not been able to bridge. With this as a model, the remaining piece of the Living Corpse Reincarnation fell into place almost immediately.
Finn had noticed the connection. He had spotted it not long after acquiring the scroll himself, turning it over during his own study sessions and thinking: Orochimaru needs to see this. The more he had read, the more certain he had become. He had even wondered, at one point, whether the original timeline had followed the same logic — whether the Shapeshifting Technique had been Orochimaru's exposure to Akatsuki resources after his defection that eventually triggered the final development of his immortality technique. It was possible. He couldn't verify it. But the resonance between the two techniques made it feel more than coincidental.
Either way, the scroll was now in Orochimaru's hands, and the reaction was everything Finn had anticipated.
Orochimaru closed the scroll. His breathing had steadied. The excitement was still there — visible in the way he held himself, in the quality of his silence — but he had pulled it back under control.
"I'll say it again," he said. "You were right. Without this, another two or three years before the technique was complete. With it, one month, perhaps two." He paused. "Do you understand what I'm telling you?"
"Tell me," Finn said.
"Immortality." Orochimaru's eyes were steady. "When the technique is finished, I will have crossed the threshold you've already crossed, by a different road. The same destination." He let that sit for a moment. "And then I will have the time to do everything I've wanted to do — explore every corner of this world's ninjutsu, develop techniques no one has imagined, master what others have called impossible." A slight pause. "By then, we will be gods, Finn."
Finn clapped him on the shoulder.
"Alright, alright — no need to get philosophical about it. The point is that the technique is useful to you, which is what I was hoping for." He grinned. "When I came across that scroll, I thought of you immediately."
Orochimaru accepted this without embarrassment. "I'm grateful. Genuinely." Then, businesslike: "The Rinnegan research and the Sharingan work — I'm putting both aside. Sasori can continue on his own, or they can wait. For the next two months, I need to be completely undisturbed. Don't call me into anything unless it's something only I can handle." He looked at Finn directly. "That includes you."
"What about my management problem?" Finn asked, with mild complaint.
"The moment the technique is finished, I'll find you someone. If nothing else works, I'll handle it myself for a period." Orochimaru said it without drama, as a simple statement of intent. Once he had crossed into immortality, time became an abundant resource. Spending some of it on administrative organization was no longer an inconvenience.
Finn looked at him for a moment, then nodded. "Fine. Go do it."
He leaned back. "As it happens, I'm not far off on my own end. The natural energy work is coming along. By the time you surface from your research, I may have Sage Mode fully sorted." He laughed. "We'll both be finishing at the same time."
That was the shape of the next several weeks, then. Orochimaru disappearing into his work. Finn doing the same. The Hidden Rain Village settling into a new, quieter rhythm under Yorozuya oversight. No major operations planned. No crises expected.
Just waiting.
The Moon Eye Project team would come eventually. Until they did, there was nothing to do but get stronger.
Far from the Rain Country, in a region that had no name worth remembering, a cave existed beneath the roots of dead stone.
Uchiha Obito moved without sound. Even the rock didn't register his footfall. He passed through the entrance and into the space beyond, and the cold inside the cave pressed against him like something alive.
He stopped at the threshold of the inner chamber.
The figure waiting inside was built from shadow and purpose, black from its layered surface to whatever passed for its core.
"Anything new?" Obito asked.
Black Zetsu turned. "Some progress. Yes."
"Good news or bad?"
"Neither, really." Black Zetsu's tone carried its characteristic measured quality — calm in the way that things with no emotional investment are calm. "We still haven't mapped Finn's actual objective. Our current working assessment is that he's fundamentally a power-seeker, but that assessment is thin. What we have found is something useful about one of his key subordinates — Orochimaru."
Obito's eyes sharpened slightly beneath his mask. "What about him?"
"Before he defected from Konoha, he developed a sudden and intense interest in the Uchiha clan's Sharingan. That interest didn't spontaneously appear — it appeared during the period he was associating closely with Finn. And when he finally left Konoha, he didn't leave empty-handed. He killed several Uchiha, took their eyes, and fled." Black Zetsu paused, letting the structure of the argument assemble itself. "A researcher with his profile doesn't pivot like that by accident. Someone guided him toward it. Given that the same person later managed to acquire the Rinnegan — something that requires understanding just how valuable dojutsu are — I believe the guiding hand was Finn's."
Obito considered this. It wasn't an unreasonable conclusion. "And?"
"They have Sharingan. They cannot use it." Black Zetsu's voice took on a faintly satisfied edge. "The techniques associated with the Sharingan — the true ones, the ones your clan kept internal — are not written down anywhere that Finn could access. Izanagi, Izanami, the deeper applications of genjutsu space. Orochimaru can study the eye. He cannot unlock what's inside it without knowing the structure of those techniques." A pause. "We, however, can provide that structure. As a gesture of goodwill. An opening."
Obito was quiet. His hand moved to his chin.
It was the kind of offer that was difficult to refuse on its surface. Finn's people wanted the Sharingan's full capability. Obito's side held the key to that capability. That made the key valuable, and valuable things made doors that would otherwise stay shut begin to open.
"If we hand them the techniques," Obito said slowly, working through it, "he'll want more Sharingan to work with. Sharingan in larger quantities means—" He stopped. Then: "Maybe he'd even be willing to move against the Uchiha clan directly. Cooperate on eliminating them."
"That's right," Black Zetsu said, with a satisfaction he didn't bother to conceal.
The clan was already marked. Obito had made that determination on his own — cold arithmetic, no sentiment involved. The Uchiha represented the single most probable source of Susanoo-level resistance to the Infinite Tsukuyomi's final phase. They had to be removed before the plan reached completion. The method and timing were the remaining variables.
If Finn could be angled into handling part of that — or all of it — through his own ambitions, then the Moon Eye Project gained a powerful instrument and spent nothing.
A gift, delivered carefully, that cost nothing to give.
Obito nodded once. "Set it in motion."
