The Safehouse Mystery

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

The Hyuga team continued onward through the thin morning mist. The scent of blood from last night's brief skirmish seemed to still linger at their noses, but no one mentioned Shu Hyuga's death—in the eyes of the Main House, it was merely the normal loss of a disposable asset.

Ko Hyuga walked at the very front of the group, the wide sleeves of his white kimono swaying lightly with each step. There was no expression on this Main House elder's face, as if he had not been the one to order the Branch House members to self-destruct 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 near the middle of the team, 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 chakra pathways like a parasite, slowly devouring their life force with every breath.

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

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

Xiao did not turn his head. He merely gave a quiet hum.

"How long can we hold on?" Tetsu's voice carried a suppressed tremor.

"If we don't fight again, about three days." Xiao answered honestly. "If a high-intensity conflict breaks out, the Curse Mark will accelerate its drain on your life force. You might... not last an hour."

Tetsu stumbled, then quickly steadied himself.

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

The team continued forward in silence. After passing through a coniferous forest, the terrain began to grow more complicated—the hills gradually gave way to steep ravines, exposed rock faces covered in moss, and the air thick with the scent of damp earth.

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

"Two kilometers ahead is an abandoned shrine. We'll use it as a temporary base." He pointed at a mark on the map. "Xiao, take Tetsu and two others to scout the shrine. Signal us after confirming it's safe."

Xiao's pupils narrowed slightly.

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

"Yes." He lowered his eyes, concealing the thoughts within them.

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

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

The four of them split from the main force and followed a path along the eastern side of the ravine.

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 filtering through gaps in the branches and falling upon the humus below. The air carried a musty odor of fungi and rotting wood, while the occasional cry of an unknown bird drifted from afar.

"This place is creepy." One Branch House member muttered under his breath.

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

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

But what truly caught his attention was beneath the shrine.

There was a faint chakra signature there, like traces deliberately concealed by some kind of barrier. Its chakra frequency was peculiar. It was neither one of the five elemental transformations commonly used by shinobi nor a summoning formula, but a more ancient, more obscure rhythm.

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

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

"Safe." Tetsu let out a breath.

"You guard the perimeter." Xiao rose to his feet. "I'll go inside and inspect it thoroughly."

"Xiao, that doesn't follow reconnaissance procedure—" Another Branch House member tried to stop him.

"Elder Xiao's order was to 'confirm safety.'" Xiao cut him off, his tone gentle yet unquestionable. "If there are hidden traps or secret chambers inside the shrine, a superficial assessment could mislead the main team. Guard the entrances. I'll be out soon."

Before his teammates could respond, Xiao had already stepped toward the shrine's main entrance.

The rotten wooden stairs groaned under his weight. When he pushed open the half-closed hall doors, a stale smell of old dust rushed at him. The main hall was even more dilapidated inside—the shrine deity's features had long blurred beyond recognition, the offering table had snapped in two, and faded wooden prayer plaques lay scattered across the floor.

But Xiao's Byakugan saw through the surface.

His gaze locked onto the area behind the shrine altar—beneath the wooden floor was a square space roughly one meter on each side. The walls of that space were engraved with dense sealing formulas, the very formulas that concealed the chakra fluctuations within.

Xiao walked to the altar and reached out to touch its mottled carvings.

The texture beneath his fingertips was ordinary: nothing more than old wood. But when he gathered chakra at his fingertips and lightly tapped the third plank beneath the altar at a particular frequency—

Click.

A faint sound of a mechanism turning.

The altar base slid half a foot to the left, revealing a narrow passage descending below. There were no stairs in the passage, only a nearly vertical metal ladder.

Xiao did not hesitate. He turned and entered the passage.

After climbing down roughly five meters, his feet reached solid ground. It was an underground chamber less than ten square meters in size, its walls built from solid bluestone blocks and engraved with sealing formulas of the same origin as those beneath the shrine floor. The air inside was abnormally dry, without even a trace of the dampness one would expect underground.

At the center of the chamber stood a stone table. On it sat a long-extinguished oil lamp, along with—

A scroll bound with 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 scroll's material was unusual. It was neither ordinary paper nor animal hide, but an almost transparent membrane that felt cold and resilient. It was covered in dense ancient characters written in dark brown ink—not the script commonly used in the modern Shinobi World, but pictographs closer to those found on Ōtsutsuki Clan monuments.

Fortunately, Xiao had spent this period studying texts concerning the Byakugan bloodline and had some familiarity with this ancient script.

He read it word by word.

<Treatise on the Origin of Curse Seals: The Ōtsutsuki Chapter>

The opening passage made Xiao's breathing catch slightly.

"The Caged Bird Seal was not created by the Hyuga Clan. Its prototype was a simplified and degraded version of the 'Karma Seal' used by the Ōtsutsuki main line to control servant races. The complete original Curse Seal could track, control, and even instantly erase its bearer across star systems, its effects persisting until the bearer's bloodline was completely extinguished..."

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

He continued reading.

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

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

The ancestors of the Hyuga Clan—very likely descendants of Hamura Ōtsutsuki—had obtained fragmented information on the Karma Seal. They tried to reproduce it, but limited by bloodline purity 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 exposed the Curse Mark's central weakness—

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

Xiao's pupils suddenly contracted.

The Ancestral Shrine Barrier.

The Hyuga Clan's ancestral shrine lay at the heart of the Hyuga Clan Grounds in Konoha Village, guarded day and night by the Main House's most elite protectors. But if the scroll's records were true, then destroying that barrier would disable every Branch House member's Caged Bird Seal at once!

He quickly flipped through the scroll's later contents.

The remainder contained speculations about the barrier's structure: the barrier required an enormous and continuous consumption of chakra to sustain, and was likely connected to some natural energy node; the core control authority should rest with the Main House head, though the specific means of operation remained unknown...

When Xiao turned to the final page, his movements stopped.

Around one-third of the page had been deliberately torn away. The tear was fresh, its edges still bearing tiny fibers. It had likely happened no more than three months ago.

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

"...the moon... 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 if the writer had left it in haste under extreme tension or weakness.

Xiao stared at those words, 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 within the Byakugan bloodline's inheritance. But if the true control core of the Caged Bird Seal was on the moon, then the ancestral shrine barrier in Konoha was likely only a relay station or secondary node.

What did that mean?

It meant the Hyuga Main House might be nothing more than pieces on a board. It meant that, at a higher level, there was another pair of eyes watching every Byakugan bloodline bearer. It meant the truth of the Caged Bird Seal was deeper and darker than imagined.

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

He did not leave immediately. Instead, he used his Byakugan to scan the entire underground chamber once more. On the bluestone slab behind the stone table, he discovered a faint line of small writing, visible only when light struck it at a particular angle:

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

There was no name at the signature, only a simple symbol: an eye bound by chains.

Xiao reached out and touched the symbol, feeling the rough edges of the engraving beneath his fingers.

He remained in the underground chamber for another five minutes. Only after confirming there were no other clues did he climb 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 traces of dust he had left behind.

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

"How was it?" Tetsu came forward, concern on his face.

"The interior structure is mostly intact. There are no traps, and no signs of recent human activity." Xiao answered calmly. "We can signal the main team to come over."

He took out a signal flare and pulled the fuse.

A burst of red fire rose into the sky, exploding into a conspicuous mark against the emerald backdrop of the ravine.

While waiting for the main team to arrive, Xiao leaned against the trunk of an ancient tree and closed his eyes. The scroll against his chest felt like a block of ice. Those words, that information, those unresolved mysteries, spun through his mind again and again.

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

Its control core might be on the moon.

The provider of the anonymous map knew these things and had deliberately guided 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 his hand to break the Caged Bird Seal, or were they leading him into some greater trap?

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

Xiao opened his eyes.

Ko Hyuga approached through the forest with two other Branch House members, his steps so light that they made no sound.

"How are things?" Ko's gaze swept over the shrine.

"The interior is safe and suitable as a temporary base." Xiao replied respectfully. "There is space in the underground chamber for stored supplies, but it is already empty."

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

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

Xiao walked last. As he crossed the threshold, he looked back toward the depths of the ravine.

According to the anonymous map, the next coordinate was twenty kilometers ahead, at 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 him, something had changed completely.

If resisting the Main House had previously been only 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 meticulously designed around him.

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

During the two-hour rest period, Xiao chose to "patrol" the shrine's perimeter.

Leaning against a tree far from the others, 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 fragmented passage describing how to remove the Karma Seal, his heartbeat skipped.

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

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

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

Third, and most crucially, the final severance ritual had to be performed on the night of a full moon, using the natural energy tides between the moon and the earth.

The night of a full moon.

Xiao looked up at the sky. It was afternoon, and the moon could not be seen. But he remembered that the full moon would arrive in three days.

And the destination of this mission, the secret Hidden Sound Village base they were to investigate, happened to be near Moonview Marsh.

A coincidence?

He did not believe in coincidences.

The anonymous map, the ancient text, the mission location, the full-moon night... these clues were like puzzle pieces gradually forming a complete picture.

Someone was guiding him, directing 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 was, one thing was certain: this was his best chance to break the Caged Bird Seal, and perhaps his only chance.

He had to go.

Even if there was a trap ahead, he would charge into it, drag out the one who set it, dismantle the trap, and swallow whatever bait lay inside.

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

A whistle calling for assembly sounded from inside the shrine.

Xiao composed his expression and headed toward the main hall.

Sunlight filtered through gaps in the canopy, casting scattered flecks of light into his pale pupils. Deep within that light, a faint azure starlight was quietly beginning to take shape.
