It's important to note that while the Caged Bird Seal is nearly impossible to break, once the user exceeds a certain range, its effects begin to weaken—and further still, say a dozen kilometers away, it becomes almost completely harmless…
Despite his young age, Neji—having trained in the Breathing Art of the Sage Path—quietly slipped out of Konoha overnight, blending in with the larger group on their journey.
Meanwhile, Uchiha Kirin had already convinced the two elders to settle with him at a coastal bay near the border of the Land of Water and the Land of Fire.
Just a few steps into the water from here and a short dive down led directly to the Dragon's Spine.
It was practically right under his nose, offering immense peace of mind.
As for setting up some kind of Shinobi Academy… that could wait until his resources were more abundant.
By now, several months had passed since his meeting with the Sage of Six Paths and the others.
He'd had his fun—now it was time to honor the agreement and steer the shinobi world back on course… by wiping out the Uchiha clan.
Of course…
That meant within the simulation.
Leaving a clone behind to look after the newly built cabin and the two elders, Uchiha Kirin transformed into a serpentine dragon and dove into the sea, heading straight for the place beneath the Water Curtain Cave.
With 63,360 Simulation Points, subtracting the initial cost still left him with over 50,000—enough for more than fifty years of 『Immersive Simulation』!
(T/N: Immersive Simulation, entering the simulation directly and gaining full control over all actions)
That already far exceeded the entire span of Naruto: Shippuden through Boruto.
"Seeing is believing. This time, I'll witness it all myself—how the so-called sages' schemes steer the course of the world."
『Ding! Confirm activation of Immersive Simulation?』
"Confirm."
『During simulation, the host's consciousness will be suspended. Please ensure you are in a safe location.』
Uchiha Kirin thought for a moment, then swiftly set up multiple layers of sealing barriers beneath Water Curtain Cave.
Next, he opened Kamui to connect to the prototype Divine Realm, pulling his true body inside. He left only a speck-sized tunnel to the outside, enough to absorb natural energy for sustenance.
『Full Simulation Rules:』
〖During the simulation, the user may exit and return to reality at any time!〗
〖The user may instantly synchronize all strength gained within the simulation!〗
〖However, only up to five newly acquired items may be brought back!〗
〖The Loot System remains active and may be used to select or change targets during the simulation!〗
〖Simulation Start〗
With a flash of light, Uchiha Kirin entered the simulation.
He carefully felt out his body and surroundings—no different from before the simulation.
The only change was that the system space had been sealed. In its place was a time-tracking system showing a maximum duration of 53 years.
A separate counter ticked off time by the second, then minutes, hours, days, months, and years.
"Maybe I could use this to defend against Genjutsu?"
After checking the system, Uchiha Kirin stepped out of the Kamui space and began to survey his surroundings.
Now fully immersed within the simulation, it was time to fulfill his promise to the Sage of Six Paths and the others.
He would manipulate the entire shinobi world like puppets on strings—mold them until they bore fruit—and then, like a field of ripe crops, harvest them again and again.
...
Leaving, he concealed his presence and quietly returned to Konoha.
Now came the critical part—he needed to construct a scenario that would both erase his own influence and recreate the Uchiha massacre.
Then, he'd take his place in the shadows, harvesting the dying Uchiha clan's bloodlines and refining them through ocular power until he could wield them to strengthen his own bloodline.
The first order of business… was to completely drive Uchiha Itachi insane.
Having just been discharged from the hospital, Itachi once again fell under Kirin's Mangekyō Genjutsu. Now, trapped within countless illusory worlds, he was forced to relive failure after failure.
In one timeline, Itachi successfully annihilated his clan—only to accidentally kill Sasuke. His faith crumbled, and he wandered aimlessly before dying, murdered or driven to suicide.
Then came another world where his body shrank—no, he became Sasuke, and Sasuke became him. This time, Sasuke destroyed the Uchiha clan.
And Itachi? He was forced to relive Sasuke's path over and over again, dying each time…
In another world, he became Uchiha Izumi. In others, he was his parents. Sometimes, he was just an innocent child within the Uchiha clan—only to be brutally slain by another version of himself before even seeing the world clearly.
Through these near-endless cycles, Itachi's worldview was gradually reshaped.
The idea of the "Night of the Massacre" and "Forging Sasuke" took root in his mind, while the line between illusion and reality became dangerously thin.
Fact was, if your ocular power was strong enough, even standard Genjutsu could rival Izanami.
But Uchiha Kirin didn't intend for Itachi to repent.
He wanted him to lose his mind completely.
Eventually, after yet another unbearable suicide, Uchiha Itachi woke from the dream.
And yet, he still remembered his mission to destroy the clan—like a machine, he mechanically sought out Obito as an ally.
At that moment, Uchiha Kirin also lifted the Genjutsu placed on Danzo and Hiruzen Sarutobi, implanting in them carefully crafted memories of being humiliated by the Uchiha clan.
Thus, Itachi and Obito, along with Hiruzen and Danzo, instantly aligned—and made the collective decision to eliminate the Uchiha.
That very night, the Uchiha clan within Konoha, men, women, elders, and children alike, were slaughtered to the last.
Even Sasuke wasn't spared.
Because Itachi could no longer distinguish illusion from reality, he slashed Sasuke, spraying blood across his own face. Only then did he snap out of it and lower his blade.
That same night, the true mastermind—Uchiha Kirin—absorbed and refined all the Uchiha bloodline from the corpses.
He ultimately obtained a drop of the purest Uchiha blood and returned to his place to begin fusing it into his own.
Of course, none of this would ever be known to the shinobi world.
According to "authentic" and "reliable" underground records passed down through the ages, the real reason for the Uchiha clan's demise was utterly obscene and disgraceful:
It was said the Uchiha clan was excessively lecherous, frequently using their Sharingan powers to treat others as their playthings. Some even claimed their depravity extended to Konoha's citizens.
When this behavior was exposed, they showed no remorse. Instead, they rallied the clan and began to toy with the Third Hokage and Danzo like puppets.
But what they hadn't foreseen… was that Hiruzen and Danzo were already having an affair!
And so, their cleverness backfired, leading to their own annihilation—and inadvertently giving rise to a legendary love story that would be gossiped about for generations.
As for the sole survivor he too became a pariah.
Much like Naruto, only a handful of people understood him—while most looked on with a mixture of hatred and fear.
They feared that once grown, this Uchiha might one day treat them as playthings too.
