The Safehouse Mystery

The border of the Land of Rice Paddies was like a scar washed by rain for years, winding between hills and dense forests.

The Hyuga squad continued onward through the morning mist. The smell of blood from last night's brief skirmish seemed to linger beneath their noses, yet no one mentioned Shu Hyuga's death—in the Main House's eyes, it was merely the normal loss of a disposable tool.

Ko Hyuga walked at the front of the group, the wide sleeves of his white kimono swaying lightly with his steps. The Main House elder wore no expression, as though he had not been the one to order the Branch House members to blow themselves up last night.

"Pick up the pace." Ko's voice was as flat as if he were telling servants to pour tea. "We must reach the first reconnaissance point before noon."

Xiao followed in the middle of the squad, his Byakugan maintaining a flawless three-hundred-and-sixty-degree field of vision. He could see the ominous black chakra within the three Branch House teammates ahead—the Temporary Enhancement Curse Seal clung to their meridian systems like parasites, slowly devouring their life force with every breath.

Tetsu Hyuga walked to Xiao's left, fine beads of sweat forming on his forehead.

"Xiao," Tetsu lowered his voice, his lips barely moving, "can your Byakugan... see the things inside us?"

Xiao did not turn his head, merely giving a quiet hum.

"How much longer can we hold out?" Tetsu's voice carried a suppressed tremor.

"If we don't fight again, around three days," Xiao answered truthfully. "If we break out into an intense conflict, the Curse Mark will accelerate its drain on our life force. We might... not last even an hour."

Tetsu staggered for a moment, then quickly steadied himself.

"The Main House..." He gritted his teeth and swallowed the rest of his words.

The squad continued onward in silence. After passing through a conifer forest, the terrain began to grow more complicated—the rolling hills gradually became steep valleys, moss covered the exposed rock faces, and the air was filled with the damp scent of soil.

Ko Hyuga stopped and took a parchment map from his robes.

"Two kilometers ahead is an abandoned shrine. We'll use it as a temporary base." He pointed to a mark on the map. "Xiao, take Tetsu and two others to scout the shrine. Confirm that it's safe, then send a signal."

Xiao's pupils contracted slightly.

An abandoned shrine—this was precisely the first coordinate marked on that anonymous map.

"Yes." He lowered his gaze, concealing the thoughts in his eyes.

Ko stared at Xiao for two seconds before adding, "The shrine may be occupied by wandering shinobi or wild beasts. Proceed carefully. If anything is unusual, retreat at once."

It sounded like concern, but Xiao understood the implication: the Branch House could die, but the intelligence had to be brought back.

The four of them split off from the main group and followed a path along the eastern side of the valley.

The deeper they went, the denser the vegetation became. The canopies of towering ancient trees blocked most of the sunlight, leaving the forest dim, with only scattered patches of light falling through the branches onto the humus below. The air carried the moldy smell of fungi mixed with rotting wood, and from time to time, the cries of unknown birds drifted from afar.

"This place is creepy," one Branch House member muttered.

Tetsu tightened his grip on his kunai, keeping his Byakugan active. "There's a chakra signature fifty meters to the left. Small animals... ignore them."

Xiao walked at the front. His Byakugan vision was clearer and covered a wider range than Tetsu's. From eight hundred meters away, he had already seen the outline of the shrine—a wooden structure badly decayed, its torii crossbeam broken, stone lanterns toppled amid the weeds.

But what truly caught his attention was beneath the shrine.

There was a faint chakra signature there, traces deliberately concealed by some kind of barrier. The chakra's frequency was unusual. It was neither one of the five elemental ninjutsu commonly used by shinobi nor a summoning formula, but something older and more obscure.

"We're here." Xiao raised a hand, signaling the group to stop.

The four hid in the shrubbery around the shrine and observed it carefully for ten minutes. There were no signs of human activity, only a few squirrels leaping between the collapsed corridor pillars.

"It's safe." Tetsu breathed a sigh of relief.

"You keep watch outside." Xiao stood. "I'll go in and inspect it thoroughly."

"Xiao, that isn't in accordance with reconnaissance protocol—" another Branch House member tried to dissuade him.

"Elder Xiao's order was to 'confirm it's safe.'" Xiao cut him off, his tone gentle yet unquestionable. "If there are concealed traps or secret chambers inside, a surface-level assessment could mislead the main group. Guard the entrances. I'll be out soon."

Without waiting for a response, Xiao stepped toward the shrine's main entrance.

The rotten wooden steps groaned under his weight. As he pushed open the half-closed hall doors, a stale scent of old dust washed over him. The interior was even more decrepit than it appeared outside—the deity statue on the altar had long since lost its features, the offering table was split in two, and faded ema plaques lay scattered across the floor.

But Xiao's Byakugan saw through the surface.

His gaze locked onto the area behind the altar—beneath the wooden floor was a square space roughly one meter on each side. Its walls were covered in dense sealing formulas, the very formulas concealing the chakra fluctuations within.

Xiao walked up to the altar and reached out to touch the weathered carvings.

The sensation beneath his fingertips was ordinary: just old wood. But when he concentrated chakra in his fingertips and lightly tapped the third plank at the base of the altar in a specific rhythm—

Click.

A faint sound of a mechanism turning.

The altar base slid half a foot to the left, revealing a narrow passage leading downward. There were no stairs within, only an almost vertical metal ladder.

Xiao did not hesitate. He flipped into the passage.

After climbing down roughly five meters, his feet touched solid ground. It was a basement of less than ten square meters, its walls built from solid bluestone blocks etched with sealing formulas of the same origin as those beneath the shrine floor. The air inside was unnaturally dry, lacking even a trace of the dampness expected in an underground space.

At the center of the basement stood a stone table. On it rested an oil lamp that had long gone out, along with—

A scroll bound with a black silk ribbon.

Xiao approached the stone table but did not touch it rashly. His Byakugan carefully scanned the scroll inside and out. Only after confirming there were no trigger traps did he untie the ribbon and slowly unroll it.

The material of the scroll was unusual—not ordinary paper or animal hide, but an almost transparent membrane, cool and pliable to the touch. Dense ancient characters were written across it in dark brown ink—not the common script of the modern Shinobi World, but pictographic symbols closer to those found on Ōtsutsuki Clan steles.

Fortunately, Xiao had spent this time studying texts on the Byakugan bloodline and had some familiarity with such ancient writing.

He read it word by word.

<Treatise on the Origin of Curse Seals: Ōtsutsuki Section>

The very first passage made Xiao's breathing hitch slightly.

"The Caged Bird Seal was not originally created by the Hyuga Clan. Its prototype was a simplified and degraded form of the 'Karma Seal' used by the Ōtsutsuki Main House to control servant races. The complete original Curse Seal could track, control, and even instantly erase the branded across star systems. Its efficacy endured until the branded one's bloodline was utterly extinguished..."

Xiao's fingers brushed across the words, feeling the slight indentations left by the ink beneath his fingertips.

He continued reading.

The scroll recorded in detail the operating principles of the Karma Seal: it was a remote-control formula based on bloodline resonance. The caster implanted their own chakra imprint into the target's genetic level. From then on, the target and all their descendants would carry that imprint in their bloodline. Once activated, the caster could sense the target's location and condition at any time, even directly seize control of their body.

The Caged Bird Seal was merely a crude imitation of this original Curse Seal.

The ancestors of the Hyuga Clan—most likely descendants of Hamura Ōtsutsuki—had acquired fragments of information about the Karma Seal. They had attempted to reproduce it, but were limited by the purity of their bloodline and gaps in their knowledge. They could only create a simplified version: it retained the remote execution function but lost precise control and bloodline tracking; it added a physical mark on the forehead as a visual identifier, but that very feature exposed the Curse Mark's core weakness—

"The control hub of the simplified Curse Seal is not the caster themselves, but a fixed 'Ancestral Shrine Barrier.' The Caged Bird Seals of all Branch House members resonate with this barrier through bloodline links. If the barrier remains, the Curse Mark functions; if the barrier is destroyed, the Curse Mark fails..."

Xiao's pupils suddenly constricted.

The Ancestral Shrine Barrier.

The Hyuga Clan's Ancestral Shrine stood at the heart of the Hyuga Clan Grounds in Konoha, guarded day and night by the Main House's most elite guards. But if the scroll's account was true, destroying that barrier would cause every Branch House member's Caged Bird Seal to fail at once!

He quickly flipped through the rest of the scroll.

The later sections recorded several conjectures about the barrier's structure: maintaining it required a constant expenditure of enormous chakra, and it was likely connected to some natural energy node; the core authority over the barrier should rest in the hands of the Main House patriarch, though the specific method of control was unknown...

When Xiao reached the final page, his movements stopped.

Roughly one-third of the page's end had been torn away. The tear was fresh, with tiny fibers still clinging to its edges. It could not have been more than three months old.

At the bottom of the remaining page was a hastily written note in the modern common script of the Shinobi World:

"...the moon... the Ancestral Shrine... the true control core is not in Konoha... I repeat, not in Konoha... must find..."

The handwriting was messy, the strokes trembling, as though the writer had left it in extreme panic or weakness.

Xiao stared at that line, his mind racing.

The moon.

Hamura Ōtsutsuki and his descendants had moved to the moon to guard the Demonic Statue of the Outer Path—this was a vaguely mentioned legend in the inheritance of the Byakugan bloodline. But if the true control core of the Caged Bird Seal was on the moon, then Konoha's Ancestral Shrine Barrier was likely only a relay station or secondary node.

What did that mean?

It meant the Hyuga Main House might only be pawns as well. It meant that on a higher level, there was another pair of eyes watching every bearer of the Byakugan bloodline. It meant that the truth behind the Caged Bird Seal was deeper and darker than he had imagined.

Xiao rolled the scroll back up and tucked it into the inner pocket against his chest.

He did not leave immediately. Instead, he used his Byakugan to carefully scan the entire basement again. On the bluestone slab behind the stone table, he found a shallowly carved line of small words, visible only from a particular angle of light:

"Successor, if you read this record, remember—never has the Hyuga Clan's fate rested in its own hands. We are all prisoners. The only difference is the size of our cages."

There was no name beneath it, only a simple symbol: an eye bound by chains.

Xiao reached out and touched the symbol, feeling the roughness along the edges of the carving.

He remained in the basement for another five minutes. After confirming there were no other clues to be found, he climbed back up the metal ladder into the shrine's main hall. He restored the altar base to its original position and brushed away the footprints and dust marks he had left behind.

When he stepped out of the shrine, the afternoon sunlight was somewhat blinding.

"How was it?" Tetsu came forward, worry written across his face.

"The internal structure is largely intact. There are no traps and no signs of recent human activity." Xiao answered calmly. "We can signal for the main group to come over."

He took out a signal flare and pulled the fuse.

Red fireworks rose into the sky, bursting into a conspicuous mark against the backdrop of the lush green valley.

While waiting for the main group to arrive, Xiao leaned against the trunk of an ancient tree and closed his eyes. The scroll in his robes was like a block of ice pressed against his chest. Those words, that information, those unresolved mysteries kept circling through his mind.

The Caged Bird Seal's prototype was the Ōtsutsuki Clan's Karma Seal.

The control core might be on the moon.

The provider of the anonymous map knew these things and had deliberately led him here.

So the question was: who was that person? A rebel from the Hyuga Clan? Or... a watcher from the moon? And what was their purpose? Did they hope to use him to break the Caged Bird Seal, or were they leading him into an even greater trap?

"Xiao." Tetsu's voice interrupted his thoughts.

Xiao opened his eyes.

Ko Hyuga emerged from the woods with two other Branch House members, their steps so light they made no sound at all.

"What's the situation?" Ko's gaze swept over the shrine.

"The interior is safe and suitable as a temporary base." Xiao answered respectfully. "There is room for storing supplies in the basement, but it has already been emptied."

Ko nodded, seemingly very satisfied with the result. "Well done. Everyone, enter the shrine and rest for two hours. After that, we'll continue toward the mission area."

The team members filed into the shrine's main hall.

Xiao walked at the back. As he crossed the threshold, he glanced back toward the depths of the valley.

According to the anonymous map, the next coordinate lay twenty kilometers ahead, in a place called Moonview Marsh.

What would be hidden there?

He withdrew his gaze, his face returning to its usual gentleness and obedience.

But deep within his heart, something had already changed completely.

If opposing the Main House had once been solely about survival, then the nature of this struggle had now escalated—what he might have to fight was a bloodline shackle that had endured for a thousand years, surveillance from the depths of the stars, an entire prison of fate carefully designed around him.

And the ancient text in his robes was the first key to prying open that prison.

During the two-hour rest period, Xiao chose to "patrol" outside the shrine.

Leaning against a tree far from the group, he took out the Treatise on the Origin of Curse Seals again and used his Byakugan to scan it word by word, imprinting every symbol and annotation deep into his memory.

When he reached the fragmentary passage concerning the method of removing the Karma Seal, his heart skipped a beat.

The passage stated that removing the original Curse Seal required three conditions—

First, the branded one's bloodline purity had to reach a certain threshold, enough to withstand the backlash of the Curse Seal;

Second, one had to obtain the caster's "bloodline key," or find the Curse Seal's control core and forcibly break it;

Third, and most crucially, the final removal ritual could only be completed on the night of a full moon, using the natural energy tides between the moon and the earth.

The night of the full moon.

Xiao looked up at the sky. It was afternoon, and the moon was nowhere to be seen. But he remembered that the full moon would come in three days.

And the destination of this mission, the secret Hidden Sound Village base they needed to scout, was right near Moonview Marsh.

A coincidence?

He did not believe in coincidences.

The anonymous map, the ancient text, the mission location, the night of the full moon... These clues were like puzzle pieces, gradually coming together to form a complete picture.

Someone was guiding him, leading him to Moonview Marsh on the night of the full moon to do something.

Xiao put away the scroll and took a deep breath.

No matter who the guide was, no matter what their purpose might be, one thing was certain: this was his best chance to break the Caged Bird Seal, perhaps his only chance.

He had to go.

Even if there was a trap ahead, he would charge into it, drag out the person who had laid it, dismantle the trap, and swallow the bait inside.

Because that was how he survived—seizing everything that could be seized in desperate circumstances, devouring everything that could be devoured, until nothing remained that could bind his fate.

A whistle calling the group to assemble sounded from inside the shrine.

Xiao composed his expression and walked toward the main hall.

Sunlight filtered through gaps in the canopy, casting fragmented specks of light across his pale pupils. Deep within those flecks of light, a glimmer of azure starlight was quietly beginning to form.
