The underground Bounty Hall was a fiercely secretive society. It maintained a strict, absolute neutrality, refusing to take any interest whatsoever in the political power struggles of the shinobi nations.
Yet, without a doubt, if one desired first-class, untainted information or wanted a specific target wiped from the face of the earth, this organization was the undisputed premier destination. It all simply came down to a single, fundamental rule: Are you willing to pay enough?
Shi Yan had originally joined the shadowy underworld organization years ago, right when Grandpa Roshi's health had first started to seriously deteriorate.
At the time, he had entertained the idea of building his own intelligence and mercenary faction from scratch. However, a pragmatic analysis of his available resources revealed it would require far too much input for too little immediate output.
Instead, he turned his sights toward this already stabilized, globally entrenched neutral network.
Operating under the dark alias of "Sword Rogue," he had quickly carved out a legendary reputation for himself.
Having never once failed a single contract, maintaining absolute, flawless execution on every high-level A-class mission, he stood unchallenged at the apex of the bounty hunter hierarchy.
Stepping through the threshold of the hidden facility, Shi Yan masked all human emotion. His naturally cold, imposing demeanor seemed to make the desolate, bleak atmosphere of the hall turn entirely freezing.
Behind a heavy iron counter sat a hooded manager in charge of the sector's transactions.
The moment his eyes fell upon the bone-masked youth, he instantly recognized the legendary killer.
Dispersing the few lingering mercenaries in the room with a sharp gesture, the hooded man beckoned Shi Yan forward into a private alcove.
"Do you have it?" Shi Yan demanded, his voice echoing with a low, chilling resonance.
The hooded fellow let out a raspy chuckle. "As long as you are willing to pay the price, there are very few things in this world that cannot be procured for you, 'Sword Rogue.'"
In response, a sudden, suffocating demonic aura descended heavily upon the room. The ambient temperature plummeted as Shi Yan's souless white eyes flashed beneath his mask. "Give it to me."
Though visually sweating and deeply shaken by the sudden spiritual pressure, the manager was a veteran of the criminal underworld who had handled countless ruthless killers.
Forcefully regaining his composure, he tapped his fingers on the counter. "Thirty-five million Ryo. Not one dime less."
Shi Yan knew perfectly well that he was being aggressively ripped off, but he had no choice.
Without a word of complaint, he handed over the massive sum of currency. In return, the manager slid a small, securely locked case across the wood.
Shi Yan scanned it with his spiritual senses, and after confirming the absolute authenticity of the contents, he turned smoothly on his heel to leave.
"You know," the hooded manager called out to his retreating back, "the higher-ups told me to remind you of their ongoing offer once again. It is quite a lucrative deal if you ask me... but then again, the choice is entirely yours."
Shi Yan didn't even pause his stride, continuing to walk out into the shadows.
The "Offer" the manager spoke of was from none other than the rogue organization Akatsuki.
Although the persona of the Sword Rogue was officially classified as an elite A-rank mercenary rather than a missing S-rank criminal, his flawless 100% mission success rate had garnered massive attention.
Furthermore, the rumors that the lethal prodigy was an incredibly young man only increased his appeal to the upper echelons of the underworld.
But Shi Yan had absolutely zero interest in participating in their destined, doomed schemes.
Because he possessed the memories of his past life, he already knew everything there was to know about the Akatsuki; they had absolutely nothing substantial to offer him.
He merely utilized the Sword Rogue identity as a convenient tool to eradicate scum, gain valuable real-world combat experience, and secure spare cash.
As a cultivator walking a heaven-defying path, he required various rare, exotic materials that could not be found within regular civilian markets.
By leveraging the Bounty Hall's vast, far-reaching black-market network, he could easily commission the retrieval of these items. It took time and cost an exorbitant amount of money, but it got the job done perfectly.
The item resting securely inside the case he currently held was the crowning achievement of that method.
'I don't have much practical use for this shadow identity anymore,' Shi Yan thought, staring up at the night sky as he left the hideout. 'I think it's finally time to start making a real impact in the light. This act of staying hidden eternally in the dark is truly not my cup of tea. True cultivators should be gallant, celebrated, and praised! Our grand stories should inspire the youths, our manliness should attract the hearts of all women, and our dashing demeanor should invite the burning envy of all men. I certainly didn't get reincarnated into this universe just to die as a pathetic, nameless bounty hunter.'
Nakamura Mansion
Reaching the absolute security of his estate, Shi Yan seamlessly switched places with his physical duplicate clone, making it appear as though he had never left the room.
Having previously instructed his servants to never disturb him during his nightly sessions, he activated multiple advanced inscription arrays around the bedchamber.
Under the protection of these runic barriers, whatever occurred inside the room could not be perceived by anyone on the outside, maintaining the illusion of a completely normal, quiet setting.
Sitting comfortably on his couch, Shi Yan reached into his cloak and pulled out the small, premium case. Unlocking it, he revealed a remarkably rare, small bluish stone shot through with a distinct, reddish tint.
"I have waited a very long time for you," he whispered, a brilliant smile gracing his features.
What he held in his hand was a genuine Spatial Stone, covertly extracted and smuggled directly from the hidden depths of Hoshigakure (the Village Hidden among Stars).
Shi Yan had spent a massive portion of his hard-earned bounty money over the years digging up information regarding unusual cosmic anomalies.
By sheer chance, he had uncovered an old archival report about a mysterious meteorite that had fallen in the Star Village—a rock possessing the bizarre property of completely vanishing into thin air on certain days, only to reappear on the exact same spot the next.
To standard shinobi, it was merely an amusing, unexplainable geographical quirk. But to an advanced cultivator like Shi Yan? He instantly recognized its true worth.
It was a pure, high-density spatial stone used exclusively for the creation of spatial storage artifacts. He had never truly expected to successfully procure such a heavenly resource in this low-energy realm.
'Thank the heavens that although my blacksmithing capabilities are virtually non-existent, my knowledge of ancient inscriptions is exceptionally advanced. With this, I can finally forge my own Spatial Ring.'
In the immortal realms, a spatial ring was considered a completely standard, baseline item for any cultivator of his caliber.
Unfortunately, that luxury did not apply to the resource-depleted Elemental Nations. If not for the unique nature of the Four Auspicious Beasts Technique—which prioritized deep elemental insight and understanding of the cosmic Dao rather than an endless consumption of rare external materials his current strength would have been severely limited.
Claming his mind and purging all stray thoughts from his consciousness, Shi Yan focused his entire soul solely on executing the delicate task with absolute perfection.
Five hours passed in total stillness.
Just as the horizon began to bleed with the soft gold of a new morning, Shi Yan let out a long, exhausted breath.
Working with spatial energy for the first time in this young body had created several minor structural inconsistencies, but through sheer willpower and flawless runic control, he had successfully pulled it off.
Resting in the palm of his hand was a magnificent piece of art. He had beforehand prepared a solid, premium ring shell forged from pure gold. Now that the spatial stone was permanently fixed into the empty slot, the artifact presented a breathtaking sight.
Sliding the band smoothly onto the ring finger of his right hand, Shi Yan admired his handiwork. The beautiful, heavy golden ring radiated an aura of ancient majesty rather than a cheap, gaudy luster, perfectly complementing the embedded azure stone that gleamed with subtle hints of scarlet fire.
"Hmm... it suits me remarkably well," Shi Yan complimented himself with a characteristic touch of narcissism. "But then again, absolutely everything does."
An unexpected, miraculous surprise manifested the moment the ring settled against his skin.
As it turned out, the star-stone still retained a dense reservoir of raw, mysterious cosmic energy trapped deep within its core.
As Shi Yan had laid down his final locking inscriptions, this pure energy had suddenly erupted, bleeding directly into his hands and flooding his meridian pathways.
Instantly, his tyrannical cultivation technique flared to life, easily suppressing the foreign energy and steering it directly into his Dantian. He reaped the massive, unexpected benefits on the spot.
A few days later, sitting in deep meditation, a soft hum of power vibrated through the room.
"I broke through," Shi Yan smiled, opening his golden eyes. He had successfully ascended to the Second Realm of the Nirvana Stage.
It was a highly unexpected, rapid gain. For reasons that still eluded his full understanding, he was capable of seamlessly utilizing native chakra as a perfect substitute for natural spiritual energy, though accumulating the sheer volume required still took a considerable amount of time.
Usually, his breakthroughs were achieved through deep bursts of philosophical insight and a profound understanding of the Dao. This particular instance marked the very first time he had accumulated more than enough raw inner energy beforehand, lacking only the final catalyst.
With this sudden influx of cosmic energy, his monstrous talent had forced open the bottleneck once more, further sharpening his spiritual senses and granting his physical physique a massive boost in destructive output.
"Rina," Shi Yan called out softly.
The door clicked open instantly, and Rina stepped gracefully into the room. Bowing deeply with immense respect, she spoke in a sweet, clear tone. "Master, the shinobi Kakashi Hatake personally delivered your commissioned item while you were away. Since you were heavily occupied, I made sure not to disturb you, and I personally handed over the full financial compensation exactly as you commanded."
Rina handed over a long, carefully wrapped package with absolute reverence, before smartly stepping back to give him space.
Over the past year, she had learned exactly how much Shi Yan valued his privacy when conducting his personal martial business.
Shi Yan nodded approvingly, watching her step away. 'She is proving to be an absolutely asset in managing both this mansion and my external business affairs,' he thought.
Shi Yan was never the type of person to simply sit back and lazily munch away on his parents' inherited wealth.
Being a modern soul from an advanced, economically driven world like Earth, he knew that leaving massive amounts of frozen assets sitting idle in a vault was a complete waste of capital.
Therefore, years ago, he had quietly established a high-end restaurant within the commercial heart of Konoha. In no time at all, its unique recipes and premium atmosphere made it the single best dining establishment in the entire Hidden Leaf Village.
To test Rina's latent organizational potential, Shi Yan had handed the entire management of the restaurant over to her—and she had handled the capital splendidly, maximizing profits without a single error.
Shifting his focus down to the long package in his hands, an intense, childlike excitement washed over him. He eagerly unwrapped the bindings, revealing the masterwork of the village's premier blacksmith.
What lay before him was a beautifully weighted, razor-sharp straight sword. The length of the blade was perfectly proportioned to the size of his arm, accented by a light-blue hilt wrapped in premium silk.
Swish!
He gave the blade a few experimental, lightning-fast swings through the empty air, listening to the crisp, clean hiss of the steel. He couldn't help but praise the artisan's unparalleled skill.
"Well... considering I provided a mountain of top-quality, legendary raw ores, it would have been an absolute crime to receive a poor blade," he murmured. "Now, let's get to the real work."
Biting his thumb, he used his own blood and pure energy to systematically lay down intricate, glowing runic inscriptions along the flat of the steel.
Soon enough, the arduous process was complete. The glowing blood-runes settled deep into the metal, adding an elegant, mystical charm to the weapon's physical beauty.
Yet, beneath that gorgeous exterior lay a tightly leashed, terrifying beast, ready to pounce upon its enemies and rip them to absolute shreds at a moment's notice.
"Now, all that's left to do is assign a proper name..." Shi Yan muttered, tapping his chin.
Naming things had never been his strongest suit, and this final part always brought a humorous amount of anguish to his mind. After pacing around the room for several minutes, a sharp smile broke across his handsome face.
He lifted the pristine steel, letting the morning light reflect off the runic engravings, and declared its eternal title: "Your name shall be... Samatage Rarenai."
The Unstoppable Blade had officially been born.
