The night of the Uchiha Massacre came to a close, and with it, the trajectory of the shinobi world had been nudged back onto its rightful path.
Uchiha Kirin, naturally, patted himself off and left, returning to seclusion to digest and consolidate his strength—leaving the rest of the stage to the Sage of Six Paths and the sages of the Three Great Sanctuaries.
Relying on the abundant energy of the Dragon Vein, he refined and purified the bloodline gathered from his clan over and over again, until not a single impurity remained.
He opened his eyes, and with powerful Ocular Power examined it closely—unexpectedly discovering traces that seemed to belong to ancient gods.
Massive amounts of rule imprints….
Among them…
Of course, after being devoured by the God Tree and diluted through hundreds of generations of descendants, even if they had now been fully reassembled, these remnants no longer held vitality—they had completely transformed into nourishment for future generations!
Uchiha Kirin was overjoyed. Without hesitation, he merged these essences into himself.
Even with his current overwhelming strength, he could feel his blood boiling under the stimulation of this compact yet potent bloodline core.
His already monstrous body underwent yet another transformation.
Countless rule imprints surged through his soul and will, drastically improving his ability to comprehend the laws of nature.
His Susanoo activated involuntarily. Originally black, it gradually became enveloped by various chaotic energies. The Susanoo, wrapped in these conflicting powers, constantly changed—growing larger, then smaller, shifting from humanoid to beast form. Its colors morphed into flames, each with a distinct will, competing fiercely to dominate this energy-forged body.
Timing it perfectly, Uchiha Kirin retracted his power and entered the Susanoo himself, allowing his body to directly absorb and adapt to this violent force—one that wasn't fire, but surpassed fire in its destructive nature.
Eventually, a new force, neither entirely purple nor black, was born amidst the raging energy within the Susanoo—a power forged of pure rule.
Upon its birth, this force absorbed all surrounding chaotic energy and then attempted to escape Uchiha Kirin's control.
"A rule-based power?" Uchiha Kirin exclaimed in surprise.
This force had emerged from a storm of chaos, instantly devouring the environment that birthed it. Then, as if sentient, it tried to flee.
He couldn't let it get away!
With a flick of his wrist, he summoned a spatial barrier to block its path.
Then, in a flash, he teleported directly to the rogue energy and seized it with one hand—only to realize that the spatial wall he had just created already had a massive hole gnawed through it.
That thing had almost escaped...
Uchiha Kirin opened his mouth and swallowed the rule-based power whole. Then, channeling his Breathing Art of the Sage Path, he circulated his strength and brought the power under control.
Before long, he had completely mastered it.
[Rule Devouring]!
Born from the chaotic remnants of divine relics within the Uchiha bloodline, they devoured each other, and the victor emerged as this new rule-based force.
It also appeared to be power from an immature God Tree Fruit, once dormant in the bloodline—now awakened and fused anew.
Uchiha Kirin reactivated his Susanoo.
Now, his Susanoo was like transparent crystal—clear and indestructible.
Compared to before, its strength had drastically improved. All the energy once representing divine remnants had been fully consumed by the newly formed Rule Devouring.
Even the three prototype Divine Tool fragments he had previously merged into the Susanoo were incinerated.
What remained was a blank, yet immensely powerful Susanoo—ready for him to inscribe his own will upon it.
"Wait… the power didn't disappear."
Uchiha Kirin carefully sensed the new Susanoo and suddenly realized that within the seemingly pure energy form, there was still an incredibly faint trace of hidden power.
「Heaven-Reversing Devour」
He stood up and leapt out of the shinobi world entirely, arriving at the edge of the galaxy, concealing himself behind a massive gas giant.
There, he unleashed a towering, full-body Susanoo—one rivaling the size of the entire shinobi world.
With both arms raised, he attempted to summon Divine Tools. The previously devoured three fragments appeared once more, intertwining with each other. The surrounding space began to warp…
Until a swirling black vortex was born, dragging in nearby stars and small celestial bodies. Then, this matter was crushed, restructured, and transformed into chakra and various energies—flooding back into Uchiha Kirin's body!
"Incredible… the legacy of the gods. This might be the true power hidden in the Uchiha bloodline!"
He drew out various Divine Tools he'd previously collected from the White Ape Sage and other sources and cast them one after another into the black vortex.
He discovered something fascinating—the more Divine Tools he offered, and the higher their quality, the greater the vortex's suction force became!
And the energies consumed by it could either be:
① Converted directly into feedback energy for his Breathing Art of the Sage Path; or ② Compressed and launched as counterattacks through his Susanoo.
In a way, it resembled Momoshiki's 「Takamimusubinokami」, but this could be endlessly enhanced by feeding in more Divine Tools and treasures.
And it didn't only devour energy—it could absorb physical matter too. It simply took longer to convert into usable energy...
In fact, when he tossed in his most powerful Demon-Suppressing Vajra, the suction force of the vortex intensified to the point of distorting the nearby gas giant!
「Heaven-Reversing Devour」—it truly was a power that defied the heavens.
If left unchecked, it could likely drain an entire planet dry in an instant.
Given enough time, it might even rival the God Tree's absorption of the Dragon Vein!
But to actually do so… Uchiha Kirin's body likely wouldn't withstand the sudden surge of power.
Still, the newly obtained divine technique and the rule-based energy it carried fed directly into the prototype of his Divine Realm:
Within that embryonic space, all the Divine Tools thrown into the vortex had now fused with the massive Tenseigan and sacred relics into a single, indestructible mass.
A core-like, irregular sphere was forming—slowly converting absorbed matter and energy into self-sustaining feedback, nourishing and expanding the miniature world...
...
Even though the newly obtained divine technique was absurdly powerful, Uchiha Kirin still felt he wasn't strong enough to fully develop or wield it to its fullest potential.
At present, he could only manage the most basic absorption and enhancement via Divine Tools. Pushing further was still shrouded in mystery...
Just as he was familiarizing himself with this new power and preparing to return home for rest, he noticed something unusual—his Sharingan was changing.
There were still six tomoe.
But now, around the outer edge of the Sharingan, a faint new ring was forming—as if preparing to host a future trio of tomoe.
The Uchiha bloodline, long suppressed by the power of the Otsutsuki, had now grown strong enough to stand shoulder-to-shoulder with the Jiao Dragon bloodline. The two surged simultaneously… even showing signs of suppressing the Otsutsuki power!
And this… was only the result of merging his clan's bloodline once.
Though it didn't drastically increase his raw strength, it granted him a powerful new technique—and opened the door to a path of limitless potential...
Uchiha Kirin was already growing restless, eager to seek out new ways to strengthen himself even further.
