Chapter 81: The Echoes of the Golden Seal
The return was silent.
Han Feng crossed the metallic gate of the Three Echoes Mountain without a flash of light or a thunderclap to announce his arrival. The world simply changed around him.
Yet the instant his foot touched the familiar stone of the Gu World, an invisible pressure swept through his body.
His meridians tightened.
His breathing faltered.
For a moment, it felt as though heaven and earth themselves were rejecting something that had no right to exist within their boundaries.
Then the sensation passed.
Han Feng stood still, waiting for the next disturbance.
Nothing happened.
The wind returned, carrying dust and dry leaves across the plateau. The scent of dead earth and ancient stone filled his nostrils. Even the spiritual energy circulating through the air felt familiar.
Almost.
He slowly extended his spiritual sense.
The surrounding Qi was abundant, perhaps even denser than before. Yet compared with the energy he had encountered beyond the gate, it felt crude and disordered.
It was like comparing a river to a blade.
Both possessed power, but their natures were fundamentally different.
Han Feng withdrew his spiritual sense.
The difference between the two worlds is greater than I thought.
He turned toward the metallic gate.
The golden inscriptions that had once covered its surface had grown dim. Some had disappeared entirely, leaving only shallow grooves in the dark metal.
The gate remained intact, but its presence felt strangely diminished.
As if something had passed through it and taken a part of its strength.
Han Feng studied it for several minutes.
He had no intention of trying to open it again.
Not without understanding what lay on the other side.
The gray-robed survivor had given him a seal and a warning, but very few answers. The man had spoken about weakening boundaries and interference from an unknown force. He had not explained who was responsible, why the gate existed, or what the so-called seed meant.
Han Feng disliked incomplete information.
Unfortunately, the world seemed determined to provide him with nothing else.
"If this gate becomes known to the major sects..."
He glanced toward the distant mountains.
"They'll turn the entire region upside down."
A passage to an unfamiliar world was more than a treasure. It was an opportunity to acquire techniques, resources, and knowledge beyond the limits of the Gu World.
It was also a potential disaster.
Any faction that discovered the gate would want to control it. Those unable to control it would try to destroy it. And those who understood its true significance might kill anyone who knew where it was.
Han Feng had no intention of remaining nearby when that struggle began.
He turned away and descended the mountain.
He had taken fewer than ten steps when something stirred beneath his chest.
A faint vibration.
He stopped.
The sensation was so subtle that he might have mistaken it for a muscle spasm if he hadn't felt the same strange presence before.
Han Feng placed a hand over his chest.
The golden seal.
It rested beneath his skin, invisible to ordinary sight. He could sense its existence without understanding how it had attached itself to him.
It wasn't a Gu.
It possessed no discernible Gu aura, no insect-like structure, and no independent will that he could detect.
Yet it was not an ordinary mark either.
It felt like a rule that had been written directly into his body.
Han Feng closed his eyes.
Deep within his consciousness, the Celestial Diagram was responding.
Its six familiar points remained in place, while the seventh flickered faintly at the edge of his perception.
The Diagram wasn't advancing.
It wasn't breaking down.
It was listening.
Han Feng's expression grew serious.
"What are you hearing?"
No answer came.
He slowly opened his eyes and looked toward the sky.
The clouds above Three Echoes Mountain moved in broad, almost imperceptible circles. Beyond them, three distant stars remained visible despite the daylight.
Red.
Purple.
Gold.
Their light was faint, but Han Feng could still distinguish them.
He remembered the disturbances that had followed him since entering the Central Region: strange dreams, spatial distortions, spiritual energy behaving abnormally, and creatures whose bodies seemed unable to obey the natural laws of their surroundings.
Now the Celestial Diagram was reacting to the same phenomena.
Perhaps the Diagram was connected to whatever was happening.
Perhaps it was merely sensitive to the same underlying force.
Han Feng refused to confuse correlation with proof.
But he could no longer dismiss the possibility.
"If you're part of the same system..."
He lowered his hand.
"...then I need to understand what that system is."
He continued down the mountain.
The vibration gradually weakened as the metallic gate disappeared behind the cliffs. It never vanished completely, however. A faint pulse remained beneath his chest, as if the seal were waiting for something to happen.
Han Feng decided to leave it alone.
For now, observation was safer than experimentation.
He had learned that lesson more than once.
The Western Region appeared unchanged.
Dry forests stretched between rocky ridges. Wild Gu crawled beneath fallen branches, while spiritual beasts moved through the distant valleys.
Yet something was wrong.
Han Feng noticed it before noon.
A flock of birds suddenly changed direction, abandoning a wide stretch of forest without any visible disturbance. Several wild Gu emerged from beneath the roots of a tree and scattered in different directions.
Farther along the road, a small spiritual beast attacked another without provocation.
The encounter lasted only a few seconds. One creature fled with a torn flank, while the other continued snapping at the empty air.
Han Feng watched from the shadows.
He released a restrained thread of spiritual sense.
The result was inconclusive.
The surrounding Qi fluctuated irregularly, but he couldn't determine whether the disturbance originated from the environment, the creatures, or some hidden formation beneath the ground.
He withdrew his perception.
Instability doesn't necessarily mean the laws of the world are changing.
There could be other explanations.
A damaged spiritual vein.
An ancient formation awakening.
A powerful Gu affecting the surrounding region.
The possibilities were numerous, and he lacked the information to distinguish between them.
Still, the pattern troubled him.
The disturbances were becoming harder to ignore.
Han Feng adjusted his cloak and continued traveling.
For the next two days, he avoided major settlements and used narrow mountain paths whenever possible. He didn't want to encounter cultivators who had heard rumors about the strange gate or the red light associated with the recent disturbances.
He also didn't want to encounter anyone who recognized the name of Elder Yin Mo.
If news of the elder's death had spread, the resulting investigation might lead directly toward the places Han Feng had visited.
He changed routes several times, concealed his spiritual fluctuations, and avoided using his Gu unnecessarily.
By the third night, he reached a rugged region filled with ravines and natural caves.
The surrounding mountains provided enough cover to conceal a small camp, while a narrow stream offered fresh water.
Han Feng inspected the area before settling beneath an overhanging rock.
Only after confirming that no one had followed him did he remove his cloak and sit down.
He had spent the past several days dealing with too many unknowns.
The foreign world.
The metallic gate.
The gray-robed survivor.
The crystal.
And now the seal.
He needed to understand at least one of them before moving forward.
His gaze lowered toward his chest.
"Let's begin with you."
Han Feng entered a meditative state.
He didn't immediately circulate his primordial essence. Instead, he used his spiritual sense to examine the golden seal from the outside.
At first, he detected almost nothing.
Its presence was faint, buried beneath the ordinary fluctuations of his body. There were no obvious channels connecting it to his meridians, and no visible connection to his dantian.
Yet when his spiritual sense approached its center, the seal responded.
A thin golden line appeared in his inner vision.
Han Feng immediately withdrew his perception.
The line vanished.
He waited several breaths before trying again.
This time, he approached more slowly.
The golden line reappeared, extending outward in three directions before disappearing beneath the surrounding layers of energy.
Han Feng studied the pattern.
It resembled neither a Gu refinement formation nor a conventional cultivation array. Its structure was simpler, but the principles behind it were unfamiliar.
The seal wasn't accumulating energy.
It was regulating the passage of something.
That distinction mattered.
Han Feng carefully directed a thread of primordial essence toward it.
The moment they made contact—
His consciousness sank into darkness.
A red sky appeared above an endless wasteland.
Jagged mountains stretched toward the horizon, their peaks stained black by some ancient catastrophe. The ground was cracked, and faint golden currents moved beneath the surface like veins beneath dead skin.
The wind carried the scent of dried blood.
Far away, weapons clashed.
The sounds were distant, yet each impact sent a tremor through the landscape.
Han Feng stood motionless.
He couldn't tell whether he was seeing a memory, an illusion, or a location connected to the seal.
He tried to move.
His body responded sluggishly, as though the world itself resisted his presence.
Then he noticed the energy.
Golden threads drifted through the air, moving in deliberate currents. They were far more refined than ordinary Qi, but their fluctuations carried a sharpness that made his spiritual sense recoil.
Each thread seemed to contain an impulse.
Not necessarily a conscious will, but a tendency toward penetration, compression, and domination.
Han Feng instinctively understood the danger.
If he absorbed that energy directly, it could damage his meridians or disrupt the balance between his primordial essence and Gu essence.
He attempted to withdraw.
The golden seal activated.
A thin barrier formed around his consciousness, separating him from the surrounding energy.
One strand slipped through.
It entered the seal, slowed, and emerged as a much weaker current.
Even then, Han Feng felt a sharp sting in his spiritual sense.
He immediately cut off the connection.
The vision shattered.
Han Feng opened his eyes with a sharp breath.
Cold sweat covered his forehead.
His primordial essence had barely moved, yet the brief contact had left him feeling as though he had just completed an exhausting battle.
He checked his meridians first.
No obvious damage.
His dantian remained stable.
The Celestial Diagram was still rotating at its usual pace, although the seventh point flickered more strongly than before.
Han Feng exhaled.
"So the seal can filter the energy."
He paused.
"Or at least, a small amount of it."
He refused to draw a broader conclusion from a single experiment.
The golden current had been weak, and the seal might behave differently under greater pressure. He had no reason to assume that it could protect him from a sustained influx of foreign energy.
More importantly, he had no proof that the energy had originated from the other world rather than from some residual imprint inside the seal.
He would need further evidence.
But the experiment had revealed something useful.
The seal didn't simply suppress the foreign energy.
It altered the conditions under which that energy could interact with him.
Han Feng looked down at his hands.
For an instant, a few golden specks had appeared around his fingertips.
They were gone now.
He checked his primordial essence again.
There was no substantial increase.
His cultivation had not advanced.
The Celestial Diagram had not gained a new point.
Even the seventh point remained incomplete.
Whatever the seal had done, it had not granted him a new realm of power.
That was reassuring.
A mysterious ability that offered immediate strength often concealed a price that only became apparent after it was too late.
Han Feng had no intention of becoming another example.
He leaned back against the rock.
"You're not a source of power."
His fingers rested over his chest.
"You're a filter."
A filter that might also serve as a key, a tracking mark, or a means of observation.
He remembered the sensation he had felt during the experiment: the faint impression that something on the other side was watching.
He couldn't determine whether that sensation came from the seal itself or from his own imagination.
But he couldn't dismiss it either.
The gray-robed survivor had given him the seal without explaining its purpose.
Perhaps the man had wanted to protect him.
Perhaps he had wanted Han Feng to survive long enough to fulfill some other objective.
Or perhaps the seal served a purpose that neither of them fully understood.
Han Feng's expression hardened.
"If you're using me, I intend to find out why."
Silence answered him.
He waited until his breathing had completely stabilized before conducting a second experiment.
This time, he didn't touch the seal with primordial essence.
Instead, he activated the Celestial Transmutation Gu.
The Rank Two Gu emerged within his spiritual sea, its translucent body marked by golden and black patterns. It circled the Celestial Diagram once, then settled near the seventh point.
Han Feng carefully directed a small amount of Gu essence toward the golden seal.
The reaction was immediate.
The seal warmed beneath his skin.
The Celestial Transmutation Gu trembled.
For a brief instant, the energy passing between them became visible to Han Feng's spiritual sense.
Three different patterns overlapped.
The first was the familiar circulation of primordial essence.
The second was the conversion pattern generated by the Celestial Transmutation Gu.
The third was something else entirely.
It possessed no recognizable circulation route. Instead, it behaved like a boundary, separating two incompatible systems while permitting a limited exchange between them.
Han Feng's breathing slowed.
So that's the difference.
The Celestial Transmutation Gu transformed energy.
The golden seal regulated contact between energies that might otherwise interfere with one another.
They were not the same ability.
Nor could one replace the other.
He cautiously allowed the two structures to interact for several breaths.
The Celestial Diagram responded with a faint pulse.
A thin golden line appeared between its central point and the seventh symbol.
Han Feng immediately froze.
The line remained for less than a heartbeat.
Then it disappeared.
He severed the connection at once.
The Celestial Transmutation Gu retreated toward the center of his spiritual sea, its glow noticeably dimmer.
Han Feng felt a dull ache behind his eyes.
The experiment had consumed more spiritual sense than he expected.
He sat motionless until the discomfort subsided.
Only then did he allow himself to smile faintly.
He had discovered a possible interaction.
Nothing more.
The golden seal could regulate the contact between foreign energy and his existing cultivation system. The Celestial Transmutation Gu might help him examine that interaction, but it could not remove the danger entirely.
And the Celestial Diagram had reacted to the process without revealing what the reaction meant.
The three components were connected somehow.
The nature of that connection remained unknown.
Han Feng closed his eyes.
If I can understand the relationship between them, I may eventually learn why the seal was placed on me.
That was enough for now.
He would not attempt another experiment until his spiritual sense had recovered.
He had no desire to turn a promising discovery into an irreversible mistake.
Night fell over the mountains.
Han Feng remained beneath the overhanging rock, recovering his strength while keeping a portion of his spiritual sense extended into the surrounding forest.
For several hours, nothing disturbed him.
Then the golden seal pulsed.
Once.
Han Feng's eyes opened.
The sensation had come without any contact from his primordial essence or the Celestial Transmutation Gu.
He immediately looked toward the sky.
The three stars were visible between the clouds.
The red star shone faintly above the western horizon.
The purple star remained farther away, almost lost among the ordinary constellations.
The golden star was different.
Its light had become noticeably stronger.
Han Feng stood.
He could feel the Celestial Diagram responding beneath his consciousness, its rotation becoming uneven as the seventh point flickered.
Then—
A sharp pain pierced his chest.
He staggered.
His vision blurred, and a metallic taste filled his mouth.
When he lowered his head, a thin line of blood had appeared at the corner of his lips.
Han Feng immediately suppressed his primordial essence and forced his breathing into a steady rhythm.
The pain faded after several breaths.
But the Celestial Diagram continued to tremble.
He didn't attempt to examine the seal.
Whatever had caused the reaction, it was not something he should provoke while his body was already unstable.
Instead, he looked toward the sky.
A strange sound echoed above the mountains.
It was faint at first, almost like the ringing of metal far beyond the clouds.
Then it grew sharper.
A single, impossible note.
As if a sword had struck the firmament itself.
The air trembled.
For an instant, the stars seemed to shift.
A narrow crack appeared in the sky.
It lasted no more than a breath.
But Han Feng saw what lay beyond it.
A red landscape.
Dark mountains.
Golden rivers of energy.
And a solitary figure standing beneath the unfamiliar sky.
Long hair moved in the wind.
A broken sword rested against the man's back.
The gray-robed survivor.
He stood perfectly still, looking toward the same point in the sky.
Then his gaze shifted.
For the briefest instant, Han Feng had the unsettling impression that the man was looking directly at him.
The crack closed.
The sound disappeared.
The stars returned to their former positions.
Han Feng remained motionless.
His heart was beating hard, but his expression gradually settled.
The seal had reacted before the crack appeared.
The Celestial Diagram had responded as well.
That suggested a connection between the three phenomena.
It did not prove that the seal had caused the crack.
Nor did it establish that the two worlds were merging.
The survivor might have been observing the same disturbance from the other side.
Or the crack might have exposed a place that was already connected to the gate.
Han Feng lacked the evidence to decide.
He wiped the blood from his mouth.
"So you're watching the same phenomenon."
He looked toward the empty sky.
"Or you're waiting for something to happen."
Neither possibility reassured him.
The survivor had been powerful enough to leave the seal inside his body without asking permission. If the man had appeared again, Han Feng doubted he could have resisted him.
That meant the seal might connect him to a being whose motives he could not judge and whose power he could not challenge.
A dangerous position.
But not necessarily a hopeless one.
Han Feng had survived worse situations by refusing to act on assumptions.
He would do the same now.
He returned to the rock and sat down.
The rest of the night passed without another disturbance.
Yet he did not sleep.
By morning, Han Feng had reached a road used by caravans and wandering cultivators.
He kept his aura suppressed and his appearance concealed beneath a dark cloak.
He needed information.
Not rumors about treasures or ancient inheritances, but reliable accounts of what was happening across the Western Region.
If the disturbances were spreading, someone would have recorded their effects.
Perhaps a merchant.
Perhaps a traveling physician.
Perhaps a sect disciple who had witnessed something they could not explain.
Han Feng intended to listen before deciding what to believe.
He soon came across a stopped caravan.
Several wagons stood along the roadside, surrounded by nervous merchants and armed escorts. Their horses were restless, and one of the spiritual beasts pulling a cart had been covered with a heavy cloth to prevent it from injuring itself.
At the center of the gathering, a man knelt on the ground.
His clothes were torn.
His face was pale.
Both hands were pressed against his ears.
"The sky has eyes," he muttered.
A merchant tried to offer him water.
The man recoiled.
"The sky has eyes. They were looking down at us."
Han Feng stopped at the edge of the crowd.
He listened without drawing attention.
A middle-aged cultivator standing nearby shook his head.
"This fellow came back from the Blood Mountains yesterday. He was part of an exploration team."
"What happened to the others?" someone asked.
The cultivator's expression darkened.
"Two are missing. One died before they reached the nearest settlement."
"And him?"
"He keeps saying that a hole opened in the sky. Claims he saw a hand reaching through it."
A few people laughed nervously.
Others looked toward the mountains.
Han Feng said nothing.
A sky distortion was plausible.
A giant hand might have been a distorted perception, an illusion, or a spiritual attack.
The man's condition did not establish what he had actually witnessed.
But the account was worth remembering.
Another merchant joined the conversation.
"That's not the only strange thing happening. My caravan passed through three settlements where the local spiritual springs had weakened."
"Could the springs be depleted?"
"All three at once? And the nearby Gu have been acting strangely."
The middle-aged cultivator frowned.
"I heard similar reports from the southern trade route."
Han Feng's attention sharpened.
"How long ago?" he asked.
The merchant turned toward him.
"Three weeks, perhaps a month. Why?"
"Because three weeks ago, I saw a wild Gu abandon its habitat without any visible disturbance."
It wasn't entirely true.
But it was close enough to avoid attracting suspicion.
The merchant studied him.
"Then you should be careful. Some people say the disturbances are spreading."
"Who says that?"
"Everyone says it. Few have proof."
The merchant gave a humorless laugh.
"That's how rumors work."
Han Feng nodded and stepped away.
He had heard enough to identify a pattern, though not enough to explain it.
Reports of unstable Gu.
Weakening spiritual springs.
Distorted perceptions.
Missing cultivators.
These phenomena might share a cause, but they could also be unrelated events magnified by fear.
The most dangerous mistake would be to treat every strange occurrence as part of a single grand scheme simply because the timing was convenient.
Han Feng had no intention of making that mistake.
Still, the situation warranted caution.
If spiritual resources began failing across the region, sects and clans would not wait for an explanation before acting.
They would secure what remained.
They would fight over territory.
And anyone connected to the disturbances might become a target.
Han Feng adjusted his cloak and continued down the road.
An old merchant spoke behind him.
"They say even the Gu Immortals have begun moving."
Another man scoffed.
"Impossible. If the Gu Immortals were involved, we'd know."
"Would we?"
The old merchant's question silenced the group.
"Some secret gates have been closed. Several patriarchs have disappeared from public view. A few major sects have ordered their disciples to return."
He lowered his voice.
"Whatever is happening, the powerful are preparing for something."
Han Feng didn't look back.
He had no way to verify the story.
But one detail mattered.
The great sects were changing their behavior.
Even if the rumors were exaggerated, powerful organizations were clearly taking precautions.
That alone made the situation more dangerous.
He continued walking until the caravan disappeared behind a bend.
Only then did he stop beneath a tree and look toward the distant mountains.
The golden seal remained silent.
The Celestial Diagram had returned to its usual rotation.
For the moment, there was nothing else to investigate.
Han Feng drew a slow breath.
He would return to the Central Region.
He would seek records of the distortions and investigate the origins of the three stars. He would also look for any mention of the gray-robed survivor, though he suspected that finding such information would be difficult.
Above all, he would avoid drawing attention to the seal.
If anyone discovered that he could withstand even a small amount of foreign energy, they might try to capture him, dissect the seal's structure, or force him to lead them to the metallic gate.
He had no intention of allowing that to happen.
He was not strong enough to fight the entire world.
Not yet.
That evening, Han Feng reached a secluded valley.
He checked the surroundings before sitting on a flat stone.
The sky was clear.
The three stars were visible again.
Red.
Purple.
Gold.
The golden star shone more brightly than he remembered, but it was impossible to tell whether the difference was real or merely an effect of the atmosphere.
Han Feng watched it for a long time.
Then he lowered his gaze and examined the Celestial Diagram through his spiritual sense.
The seventh point remained incomplete.
The golden seal rested beneath his chest, quiet and inaccessible.
The Celestial Transmutation Gu had recovered most of its strength, while the Dual Chaos Larva remained stable.
Nothing had changed in any way he could measure.
And yet he felt that he had crossed an invisible boundary.
He now possessed a connection to something beyond the known limits of the Gu World.
That connection might become useful.
It might also destroy him.
Han Feng accepted both possibilities.
Power was never valuable merely because it was mysterious. Its value depended on whether he could understand it, control it, and survive its consequences.
He closed his eyes.
"I will survive."
The words were quiet, almost lost beneath the wind.
After a moment, he opened his eyes again.
"And if this disturbance creates an opportunity, I'll use it."
He didn't promise to conquer the unknown world.
He didn't promise to surpass every Gu Immortal.
He simply decided that he would not allow fear to make his choices for him.
The wind swept across the valley.
Far above, the golden star flickered once.
Inside Han Feng's consciousness, the seventh point of the Celestial Diagram answered with a faint pulse.
Neither reaction lasted long enough to reveal its meaning.
But somewhere beyond the boundaries of the Gu World, a man with a broken sword stood before a dark-metal gate.
He examined the fading golden inscriptions.
Then he looked toward the distant sky.
"The seal has responded."
His voice carried no surprise.
Only uncertainty.
For several moments, he remained silent.
At last, he turned away from the gate.
"The seed is still unstable."
He paused.
"And the vessel has begun to notice."
A cold wind passed through the ruins.
The man rested his hand on the broken sword at his back.
"Then we have less time than I thought."
He disappeared into the red landscape.
Behind him, the metallic gate remained silent.
And in the Gu World, Han Feng continued his journey, unaware that the man who had given him the seal was now questioning whether he had made the right choice.
The stars shone above both worlds.
For now, the boundary between them remained.
But something had begun to answer from the other side.
