The darkness was absolute, broken only by the faint blue glow of Renjiro's Sharingan as he moved through the subterranean corridors. Dust hung in the air, thick and undisturbed for years, swirling lazily in the wake of his passage. His footsteps made no sound—he had learned long ago how to walk without disturbing the silence, how to exist in spaces where his presence would leave no trace. The walls were rough-hewn stone, damp with condensation, marked here and there with symbols that had been scratched into the surface and then partially erased.
This was the third facility he had visited in his second run. The first had been a burned-out shell, its secrets turned to ash long before his arrival. The second had been booby-trapped—not heavily, just enough to kill a careless investigator. This one was different. This one felt... abandoned. Not destroyed, not sanitised, simply left behind.
Orochimaru either left in a hurry, Renjiro thought, his eyes scanning the corridor ahead, or he deliberately left breadcrumbs behind. Either possibility is dangerous.
He had learned from his previous mistake. The clone that had been destroyed in the Land of Hot Water had taught him a valuable lesson: Orochimaru was not careless, and his facilities were not unprotected. Since then, Renjiro had changed his approach. He no longer assumed that abandoned meant empty; he swept every room with sensory techniques, checking for chakra traces, hidden seals, and surveillance mechanisms.
Tonight, he was doing the same.
His Sharingan pierced the darkness, revealing the layout of the corridor ahead. His chakra field extended outward, brushing against the walls, the floor, the ceiling, searching for any sign of recent activity. He had already completed three sweeps of the exterior, checking for traps and escape routes, before entering.
He had confirmed that there were no active seals, no lingering chakra signatures, no indication that anyone had been here in months.
And yet, he could not shake the feeling that he was being watched.
The corridor opened into a larger chamber—an operating room, by the look of it. Renjiro stopped at the threshold, his Sharingan sweeping across the space. Rusted surgical tables stood in the centre, their surfaces stained with substances that had dried long ago. Glass containers lined the walls, their contents long since emptied, their labels faded and illegible. Restraints dangled from the tables—leather straps, metal cuffs, the kind of equipment used to hold subjects in place during procedures that they would not have consented to.
He stepped inside, his footsteps silent on the cracked tile floor. The air was cold, damp, carrying the faint, acrid smell of old chemicals and older decay. Broken glass crunched under his boots—crunch, crunch—the sound unnaturally loud in the oppressive silence.
Orochimaru's work, Renjiro thought, his gaze moving across the room. Human experimentation. Body modification. The pursuit of immortality through any means necessary.
He had expected horrors. He had read the reports, reviewed the intelligence, studied the patterns. Finding evidence of Orochimaru's crimes no longer surprised him. It simply confirmed what he already knew: the Snake Sannin was a monster, and the village was better off without him. But he wasn't.
He moved on.
The storage chamber was a graveyard of failed experiments. Rows of shelves lined the walls, each one filled with jars and containers, their contents preserved in murky fluids. Renjiro paused, his Sharingan scanning the labels, searching for anything useful. Most were illegible—the ink had faded, the paper had yellowed, the writing had become incomprehensible. But a few were still readable.
Subject 47: Failure. Chakra rejection. Expired on [illegible].
Subject 52: Partial success. Integration at 23%. Status: Terminated.
Subject 61: Awaiting disposal.
He did not open the jars. He did not need to see the contents to know what they were. The labels were enough.
This was a processing facility, Renjiro realised. Not a research laboratory—not primarily. A place where subjects were prepared, experimented upon, and disposed of when they were no longer useful.
He thought of the missing children reports, the disappearances of bloodline users, the black-market medicine thefts. All of it connected, all of it pointing toward Orochimaru's network of hidden facilities.
The trail is becoming clearer, he thought. I'm getting closer than before.
He took out a small notebook—a leather-bound journal that he had filled with names, locations, and observations over the past weeks. Flipping through the pages, he found the entry for this facility and crossed it out.
Facility 17: Abandoned. No usable intelligence. No signs of recent activity. Recommend further investigation if new information becomes available.
His pen scratched against the paper—scritch, scritch—the sound loud in the silence.
He moved to the research office, a small room adjacent to the operating chamber. A desk sat against the far wall, its surface covered in papers that had yellowed with age. Renjiro approached, his Sharingan scanning for traps, and began to sort through the documents.
Most were useless—old notes, incomplete records, observations that had been superseded by later research. But a few were valuable. A map, marked with locations that he did not recognise. A list of names, some of which he had seen in the missing children reports. A letter, partially burned, that referenced a facility in the Land of Rivers.
Another lead, he thought, carefully folding the documents and placing them in his pouch. Not a strong one—but a lead nonetheless.
He took out a second scroll—a larger one, this, containing the compiled intelligence he had gathered over the past weeks. Unrolling it on the desk, he began to add the new information, cross-referencing it with what he already knew.
Becoming Jonin Commander has given me access to information previously unavailable, Renjiro reflected as he worked.
Konoha's intelligence network is massive—much larger than most shinobi realise.
ANBU reports, mission records, border intelligence, archived investigations, civilian reports—all of it flowed through the Hokage's office, and as Jonin Commander, Renjiro had access to most of it. He had spent hours in the archives, reading through old files, connecting dots that had been scattered across decades.
Much of this infrastructure was strengthened over years of work by Danzo and Konoha Intelligence, he admitted. He did not approve of Danzo, but he could not deny the effectiveness of the information network that Danzo had helped build.
The compiled intelligence was organised into categories.
Missing Children: Strange disappearances, no ransom demands, victims from multiple regions. The pattern was subtle—a few children here, a few there, easily dismissed as runaways or accidents. But when you looked at the numbers across decades, the scale became apparent.
Black-Market Medicine Thefts: Medical supplies stolen in unusual quantities. Surgical equipment disappearing from hospitals and clinics. Specialised medicines repeatedly targeted. Orochimaru's experiments required resources, and those resources left trails.
Abandoned Battlefield Morgues: Reports of corpses vanishing from battlefields. Missing remains after conflicts. Suspicious activity around war dead. Orochimaru's fascination with bodies and bloodlines did not end with the living.
Bloodline User Disappearances: Scattered reports from multiple countries. Small patterns individually, but significant when combined. Rare kekkei genkai, isolated clan survivors, wandering shinobi—all of them potential subjects for Orochimaru's experiments.
White Snake Rumors: Sightings from travellers, villagers, mercenaries. Dismissed by most authorities as superstition or misidentification. But Renjiro knew better. Orochimaru's summons and symbolism were distinctive, and where white snakes appeared, the Snake Sannin was often nearby.
Underground Surgeons: Illegal medical practitioners, black-market clinics, reports of unusual surgeries. Connections to experimental procedures that should not have been possible outside of a well-funded laboratory.
Renjiro studied the compiled intelligence, his finger tracing lines across the map, connecting locations, identifying clusters.
The pattern is hidden in the logistics, he concluded. Supplies, bodies, bloodlines, medical activity—all of them point in similar directions. Orochimaru rarely leaves direct evidence. But he cannot hide the infrastructure required to support his work.
He identified overlapping geographic regions. Several locations appeared repeatedly in separate reports—small towns near the border, isolated villages in the mountains, abandoned military outposts that had been repurposed.
These are the most likely next hideouts, he concluded, marking them on the map. Not certain—but probable.
He eliminated false leads, narrowed possibilities, and arrived at a strong conclusion.
The Land of Rivers. The northeastern region, near the border with the Land of Fire. Several reports point toward that area—missing children, medicine thefts, white snake sightings.
He rolled up the scroll and stored it in his pouch, alongside the documents he had collected.
The facility had nothing more to offer. Renjiro took one last look around—at the rusted tables, the empty jars, the faded notes—and turned to leave.
His exit was clean. No mistakes, no carelessness, no obvious evidence left behind. He had used all reasonable precautions: sensory sweeps, trap detection, chakra masking. He had not touched anything that could have been booby-trapped. He had left no footprints, no fingerprints, no traces of his presence.
The operation was clean, he thought, emerging into the night air. The stars were bright overhead, scattered across the darkness like scattered seeds. The wind was cool, carrying the scent of pine and distant rain.
He began the journey back to the next destination, the next lead, the next step in the hunt.
Somewhere hidden, in a location that Renjiro had not discovered, a snake stirred.
It was small—no larger than a finger—its scales pale white, its eyes red. It had been hiding in the shadows of the facility's entrance, watching as Renjiro passed, its chakra suppressed to near nothing. It had not moved, had not reacted, had not given any indication that it was alive.
Now, it slithered through the darkness, moving toward a hidden crevice, where a communication seal had been prepared. It touched the seal, and its observations were transmitted.
The seal glowed, then faded. The snake returned to its hiding place, waiting for further instructions.
