Uchiha Kirin had no intention of choosing anything tainted by corruption.

After all, regardless of the degree of pollution, he'd still have to spend Simulation Points to purify it—and right now, he was saving up hundreds of thousands of points to fully immerse himself in a deep, all-consuming simulation.

Besides, those corrupted items weren't anything particularly rare. The Rinnegan was right there. If he wanted it, it would be better to just purify it through the Loot System—more efficient and completely free.

As for the Rule of Lightning, while it was indeed rare, this recent simulation had made one thing clear to Kirin: the bloodline of the dragon he had fused with was inherently attuned to rules.

He now understood his natural affinity for fundamental forces.

Capturing the Rule of Lightning himself wouldn't be difficult at all for him at this point...

As for one of the Sage of Six Paths' fingers? Who even knew if it was useful...

"System, I choose options 1, 2, 3, 4, 6, 7, and 8!"

...

As soon as the words left his mouth, Uchiha Kirin felt a rush of heat coursing through his body. He instantly left behind a wooden clone and dove into the lake in the form of a massive white serpent.

What followed was an overwhelming transformation of both spirit and flesh—several Rule Forces manifested from thin air, relentlessly tempering his body and soul.

Kirin felt every part of himself boiling, not with pain, but with an indescribable euphoria that surpassed any physical sensation.

His strange breathing technique activated instinctively, devouring spiritual and physical energy at a terrifying pace, allowing his rapidly strengthening body to adapt.

A formless sword aura descended upon his consciousness, suppressing the raging energy and bringing order. All around him, the surging forces—chakra or otherwise—retracted and calmed.

As the boiling sensation faded, Kirin curiously extended a claw to inspect his serpent body. He guided the invisible sword aura across his scales and fangs, playing with it like it was an extension of himself.

Breathing techniques that balanced mind and body were only the foundation. The true key that allowed him to fully control his power and even push his potential beyond 200%...

Was this—the Ultimate Meaning of Swordsmanship!

Or rather, it was a mysterious existence forged from human will, capable of rivaling the natural rules themselves!

Uchiha Kirin stretched out his body. The Rules of Water and Fire swirled around the sword's Ultimate Meaning, gently guiding the warm lake water to ripple across his scales like a soothing massage.

"...Wait, warm lake water?"

That thought snapped him out of his trance. He immediately shrouded himself in the Rule of Void to conceal his presence and poked his head above the surface.

What he saw was a calm, mist-shrouded lake that now radiated heat like a giant hot spring. Even more strangely, a mouth-watering aroma filled the air.

His stomach growled uncontrollably.

All around him, small fish and shrimp floated to the surface, fully cooked by the heat he'd unknowingly released from his body.

A peaceful lake... had now become a giant pot of hot soup.

Kirin looked around nervously. Fortunately, this place was always quiet and close to the clan leader's residence. No one usually came here—except for Uchiha Itachi, who sometimes brought Sasuke to train.

While Kirin was pondering how to deal with the situation...

His stomach growled again.

"So hungry..."

Not one to be picky, he simply devoured the freshly cooked fish and shrimp. Even though they were plain—not even seasoned with salt—they somehow suited his taste perfectly.

But even an entire lake's worth of aquatic life was barely enough to ease his hunger. In just a few gulps, his massive white serpent body had cleared everything out.

The hunger only slightly faded.

Reluctantly, Kirin began to slow down his breathing technique. Clearly, this mysterious art—which could absorb spirit energy, unlock hidden potential, and even synchronize body and mind to resist soul-based attacks from the Sage of Six Paths—

Had its downsides.

Once activated, it drastically increased his metabolism. With a body this enormous, maintaining it in the real world would probably consume all the food in the entire shinobi world.

Even reverting to a less powerful humanoid form and putting some of his cells to sleep didn't make maintaining this terrifying physique any easier.

Kirin wiped imaginary sweat from his brow and let his mind wander.

"...If Uchiha Itachi ever holds a funeral, would it be wrong for me to crash it for the food?"

"Uh-oh, someone's coming!"

Now fully merged with the Ōtsutsuki bloodline, his sensory abilities had become incredibly sharp. And with the power of Ultimate Meaning, he could unleash his full potential—

Allowing him to perceive movements even thousands of kilometers away and predict intentions with frightening accuracy.

"Seriously? You drink too much and come pee in the lake? What kind of ninja are you!?"

Kirin immediately slithered ashore and shifted back into his human form. He waved his hand to dispel the mist and restored the lake's temperature to normal.

Then, suppressing his disgust, he headed into the forest to check his Status Panel.

...

"Eh? Why is it suddenly so cold—no, wait—frozen!?"

A cold gust of wind blew past, followed by the panicked screams of three uncivilized fools trying to defrost themselves with Fire Style jutsu and kunai...

Listening to the pleasant chorus of screams, Kirin casually claimed his loot.

...

〖Target of this hunt confirmed dead〗

〖Drawing two highest-value items〗

1. Lightning Chakra

2. Seed of Indra's Will

A surge of lightning energy instantly coursed into his body, and a phantom-like purple seed appeared in his palm. Without hesitation, Uchiha Kirin stored it inside his [System Space].

Uchiha Kirin stared at the drastically upgraded Status Panel.

While thrilled by his overwhelming power, he couldn't help but sigh.

Unknowingly, he had already mastered three entirely different yet interwoven cultivation systems...
