Konoha --- Team 7's Training Ground
Day four after the scroll.
Six in the morning.
Sasuke was already there when Bai Yan arrived.
He'd been there since five-thirty.
Running through the Chidori calibrations he'd done every morning for months.
Methodical.
Efficient.
Already warm when Bai Yan stepped through the entrance.
Bai Yan stood at the edge of the training ground and watched for a moment without announcing himself.
He did this habitually.
Not to assess.
Just to see what someone looked like when they didn't know they were being watched.
What Sasuke looked like was: precise.
Every movement deliberate.
Every repetition slightly refined from the one before.
The way of someone who had been training alone for a very long time and had learned to be his own teacher because there wasn't always someone qualified available.
He finished a set.
Turned.
"You've been there for two minutes," he said.
"Three," Bai Yan said.
Sasuke didn't bother acknowledging this discrepancy.
"The Six Paths seed," he said.
"Yes," Bai Yan said. "But let's walk through what you already know first. It saves time."
Sasuke folded his arms.
"The seed is a condensed fragment of Hagoromo's power," he said. "The scroll described it as an early precursor to Six Paths chakra control. It needs cultivation to develop --- it's not immediately accessible. The cultivation process involves aligning my existing chakra pathways with the seed's energy signature, which is different in nature from standard elemental chakra." He paused. "And it probably requires someone who understands Ōtsutsuki energy structures to guide the early stages, because getting it wrong at the foundation sets a ceiling on the final development."
Bai Yan looked at him.
"How long did it take you to work that out?" he asked.
"Two days."
"You worked it out from the scroll's single-sentence description."
"And inference."
"The inference required understanding Ōtsutsuki energy theory."
"I read what was available. It wasn't much."
Bai Yan thought about a twelve-year-old spending two days running inference on a sentence from a magical scroll and independently deriving a reasonably accurate model of Six Paths chakra cultivation foundations.
"Good," he said. "Your model is approximately correct. Let me refine three points."
Sasuke uncrossed his arms.
Listened.
Bai Yan walked him through the corrections.
The first: the alignment process wasn't about changing his existing chakra pathways, it was about creating a new parallel layer that ran alongside them.
The second: the seed's energy signature was closer to natural energy than to elemental chakra, which had implications for the cultivation speed.
The third: the ceiling wasn't set by the foundation --- the ceiling was determined by the will behind the cultivation, which was why the scroll had issued it to Sasuke specifically.
Sasuke absorbed this.
"The will," he said.
"Yes."
"That's the same language as Naruto's anchor preparation."
"Similar principle. Different application."
"What's the difference?"
Bai Yan thought about how to say this precisely.
"Naruto's anchor requires the will to hold something in place," he said. "Yours requires the will to become something. The seed responds to intention as much as technique. You have to know what you want to do with it."
Sasuke was quiet.
He looked at the training ground.
At the split post from two days ago.
"The scroll evaluated Itachi," he said.
"Yes."
"It said his story isn't finished."
"Yes."
"And it called him the man who loved his village more than his village deserved."
"Yes."
Bai Yan waited.
"The Six Paths seed," Sasuke said slowly. "The scroll gave it to me. Knowing what the evaluation said about my future trajectory. Knowing what the footage showed." He paused. "It showed me leaving Konoha. Joining Orochimaru. Going after Itachi."
"Yes."
"Why give that person a seed of Hagoromo's power?"
The question came out flat and direct.
Not self-pitying.
Just --- genuinely asking.
The way Sasuke asked things when he actually wanted to know and wasn't performing.
Bai Yan looked at him.
He thought about the answer he could give.
The strategic one.
The scroll-logic one.
He gave the true one.
"Because the scroll doesn't rank who you are right now," he said. "It ranks the distance between what you are and what you could become. And what you could become --- eventually, after everything --- is someone who understands both what the Uchiha were and what the shinobi world needs." He paused. "That understanding is worth cultivating even if the path there is crooked."
Sasuke held his gaze.
"The scroll saw the footage," Sasuke said. "The future footage. Leaving. Orochimaru. All of it."
"Yes."
"And it still---"
"Sasuke." Bai Yan said his name the way Ayame said things she meant completely. "The scroll ranked you second on the Future Pillar ranking. It put you and Naruto as first-place placeholders on the rivals ranking. It gave you the Six Paths seed." He paused. "The scroll knows what you did in the future and gave you a tool for becoming someone better anyway."
"Why."
"Because it probably figures you will."
Sasuke looked at him.
At the man who had spent seven years watching from the edges and had started, four days ago, actually being present.
"You gave Naruto the answer to do I have to do it alone," Sasuke said.
"Yes."
"What's the equivalent for me?"
Bai Yan was quiet for a moment.
"Nobody is asking you to be Itachi," he said. "Or your father. Or the last Uchiha bearing the weight of everything the clan lost." He paused. "The seed doesn't need you to be any of those things. It just needs you to be Sasuke."
Sasuke was quiet.
"What does that mean," he said.
"I think you know."
"I'm asking you."
Bai Yan thought about it.
"It means the person who told Naruto you have enough things when he wanted a rival seal," he said. "The person who trained for six hours without being asked and stayed. The person who said we're teammates like it was a complete sentence."
Sasuke said nothing.
He looked at the split post.
"That person," he said finally, "has also spent twelve years deciding that grief is a reasonable motivation for everything."
"Yes," Bai Yan said. "And the scroll gave that person a seed of Six Paths power anyway. That's the point."
A long silence.
The morning birds were doing something in the trees at the training ground edge.
Ordinary sound.
Comfortable.
"Okay," Sasuke said.
He sat down cross-legged in the center of the training ground.
"Show me the first stage," he said.
Bai Yan sat across from him.
"Close your eyes," he said. "You're going to feel two distinct chakra signatures inside you. Your standard pathways and the seed. They'll feel different in texture. Tell me when you can distinguish them."
Sasuke closed his eyes.
Forty seconds of silence.
"I can feel them," he said.
Bai Yan blinked.
"...How clearly?"
"The seed feels---" Sasuke paused, searching for words. "Like water from a different river. Same category. Different source."
Bai Yan looked at him.
He'd expected ten minutes for that step.
Maybe twenty.
"Good," he said. "Don't try to merge them yet. Just be aware of both simultaneously."
"Already am."
"...How long?"
"Since you told me they'd be distinct."
Bai Yan sat with this for a moment.
He thought about the rivals ranking.
About come back in ten years.
About what it meant that these two twelve-year-olds were going to be the best in history.
He thought about the scroll being right about things.
"Second stage," he said. "Don't rush."
"I know," Sasuke said.
They kept going.
Two hours later.
Sasuke was still cross-legged.
Eyes still closed.
The training ground quiet around him.
Bai Yan had said approximately forty words in the last hour.
Which was, he was discovering, roughly the right amount for this student.
He watched the chakra signatures shifting around Sasuke.
Not visible to the naked eye.
But perceptible if you knew what to look for.
The seed was moving.
Not fast.
Not dramatically.
But it was no longer entirely static.
It had begun, very slowly, to orient toward the surrounding network of pathways.
Like a plant finding the direction of light.
He didn't say anything.
He let it happen.
Sasuke opened his eyes.
"It moved," he said.
"Yes."
"I didn't do anything."
"You did the right thing," Bai Yan said. "Which was nothing. The seed responds to intention. Your intention right now is to become something. You don't need to force it."
Sasuke looked at his hands.
"...It feels different," he said.
"It will continue to feel different as the cultivation progresses." Bai Yan paused. "You should know it's slow. Weeks, minimum, before you see functional changes."
"We might not have weeks."
"I know." He was quiet. "But weeks of cultivation is still better than no cultivation. And the seed will respond to urgency if the situation requires it." He paused. "It's part of what it is. It was given to you by a scroll that knows the timeline."
Sasuke absorbed this.
He looked at the split post.
"Naruto asked me yesterday if I was scared," he said. Not to anyone specifically.
"I know," Bai Yan said. "I heard."
"I said not of Kaguya."
"I know."
"I said I was scared of not being ready in time."
"Yes."
Sasuke was quiet.
"That's still true," he said. "But it's---" He paused. "It's smaller than it was yesterday."
Bai Yan looked at him.
"Yes," he said simply.
They sat in the training ground in the morning.
The seed moved, very slowly, like something coming to life.
Group Chat:
[Uchiha Sasuke @Second Hokage Tobirama Senju: The Six Paths seed and the Sharingan's chakra network. Is there documented interaction between them?]
[Second Hokage Tobirama Senju: Not documented. Theorized.]
[Uchiha Sasuke: By whom.]
[Second Hokage Tobirama Senju: Myself. In research notes that Orochimaru stole. Which means Orochimaru has incomplete theories about exactly this interaction.]
[Uchiha Sasuke: What did the theories conclude.]
[Second Hokage Tobirama Senju: That the Sharingan is, in origin, a degraded form of Ōtsutsuki chakra sensitivity. If the Six Paths seed cultivates properly in someone with the Sharingan, the Sharingan's perception capabilities could develop in unexpected directions.]
[Uchiha Sasuke: Unexpected how.]
[Second Hokage Tobirama Senju: That's where my notes end. I hadn't finished the analysis when Orochimaru took them.]
[Uchiha Sasuke: ...]
[Uchiha Sasuke: I'll find out.]
[Second Hokage Tobirama Senju: I assumed you would.]
[Second Hokage Tobirama Senju: Don't tell Orochimaru before you've developed it fully.]
[Uchiha Sasuke: Obviously.]
Group Chat (private channel):
[Bai Yan @Second Hokage Tobirama Senju: He distinguished the two chakra signatures in forty seconds.]
[Second Hokage Tobirama Senju: ...Forty seconds.]
[Bai Yan: Yes.]
[Second Hokage Tobirama Senju: ...]
[Second Hokage Tobirama Senju: Keep me updated.]
