Uchiha Jin was in a foul mood.
Just then, Uchiha Yue walked in carrying tea.
She looked completely gentle. After kneeling beside Uchiha Jin, she began to pour for him and said, "I don't know what's troubling Lord Jin, but please have some tea and relax."
"Things always work out in the end. You're already outstanding—don't put so much pressure on yourself."
Uchiha Jin took the cup. Looking at Uchiha Yue, his mood instantly brightened.
The girl was warm, humble, and carried no arrogance—every inch the ideal Yamato Nadeshiko.
Back in his previous life, a beauty of this caliber would have been far beyond his reach.
But now?
She'd been placed at his side, waiting on him carefully every day; it was impossible to stay gloomy.
"Mm, got it."
Uchiha Jin nodded.
Meanwhile…
Seeing him still frown, Uchiha Yue rolled her eyes and said, "By the way, Lord Jin."
"I remember Elder Fugaku wanted to change his second son's name, yet you insisted on keeping 'Sasuke.' What were you thinking?"
"I really don't believe you were currying favor with Hiruzen Sarutobi."
She only wanted to lighten his mood, so she shifted the topic.
Yet…
She was genuinely curious.
At first, Elder Fugaku had named the boy Sasuke precisely to win Hiruzen's favor.
Later…
As clan–Village relations soured, Fugaku wanted to rename him, but Uchiha Jin stopped it.
Everyone was stunned.
Still, trusting Jin, Fugaku kept the name.
No one had dared ask why—till now, when Yue voiced the question.
Meanwhile…
Hearing it, Uchiha Jin burst out laughing.
"The name Sasuke?"
"I didn't overthink it. Sasuke Sarutobi was Hiruzen's dad, so when Hiruzen sees little Sasuke, won't he have to call him Dad?"
"If that happens, Fugaku becomes Hiruzen's grand-dad."
Uchiha Jin spoke casually.
Uchiha Yue was dumbfounded—probably no one in the entire Ninja World would have linked that.
No way around it…
In this world, naming a child after the deceased is a tribute, totally different from Jin's past life.
Now that he'd pointed it out, Yue suddenly found the custom too cringeworthy to look at straight.
Utterly eye-burning!
Couldn't exactly say Fugaku named his son just to become Hiruzen's grandpa, right?
After the laughter, Yue reminded him, "Lord Jin, don't mention this outside. Sasuke isn't the only case; many name children to honor dead heroes."
Uchiha Jin nodded.
He wasn't stupid; he knew what to keep quiet about.
Shortly after…
They chatted a bit more. Noticing his improved mood, Yue bowed and took her leave.
Clearly…
She knew her place—staying had only been to cheer him up.
Now that he felt better, it was time to go.
Not disturbing his thoughts was ingrained in her.
As for that…
Uchiha Jin didn't stop her. Once she left, he looked again at the pagoda pendant in his hand.
Suddenly…
He thought of one method he hadn't tried—
Yin Release!
In plain words: spiritual power, or Mangekyō Dōjutsu Power.
Acting at once, he didn't hesitate.
When Uchiha Jin opened his eyes again, the three tomoe spun wildly, turning into his unique Mangekyō.
Almost instantly…
A chill filled the room.
Guiding the Dōjutsu Power, he slammed it into the tiny pagoda pendant.
"It's working!"
Sensing the ocular energy merge with the pagoda, his eyes lit up.
However…
Just as he was about to pour in more power, the seven-storey pendant flashed into light and fused into his body, anchoring itself in what he could only call his "Sea of Consciousness."
Of course…
That was only his best guess—he'd never studied Daoist texts in his past life.
All he knew was it wasn't an organ; it was something far more mystical.
In his perception it was an endless ocean, yet the waves were pitch-black and gave off an ominous feeling.
After closer inspection, it felt much like his Dōjutsu Power.
But here was the problem…
Dōjutsu Power should stay in the eyes; he'd even seen his Susanoo resting quietly inside them.
So he was certain this place wasn't his eyes or any other organ.
Therefore…
The only term he could think of was "Sea of Consciousness."
Boom!
At that moment the seven-storey pagoda expanded, releasing a golden light that swept across the black ocean.
Next…
Jin saw countless Sealing Jutsu formulas appear above the dark sea—only to be shattered by the golden glow.
Immediately…
He felt his eyes link to this vast ocean.
This boundless black sea was indeed his Dōjutsu Power; it had simply been sealed, allowing him to use only a pitiful sliver within his eyes.
Why?
Uchiha Jin's face turned ashen.
Chakra originated from the God Tree, and in the original story Ōtsutsuki Kaguya could absorb everyone's Chakra. The tree itself belonged to the Ōtsutsuki Clan.
So, wildly speculating: the so-called Eternal Mangekyo Sharingan—achieved only by swapping eyes with a sibling—what is its real nature?
Could it be that every Uchiha's Dōjutsu Power was originally limitless?
But some unknown power of the God Tree—or Hagoromo, the so-called progenitor of Chakra—deliberately sealed each Uchiha's power, leaving them able to use only a tiny fraction?
Eternal Mangekyo Sharingan…
