Chapter 11: The Second Door
The old road had been erased from every updated map issued by the Regional Council.
According to public records, the route ended at an abandoned trading post built before the Convergence to facilitate the transportation of minerals between two mountainous regions. Beyond that point, the maps showed nothing but uncharted terrain.
The unofficial maps told a different story.
There, the road continued for more than a hundred kilometers, winding through narrow valleys, ruined formations, and territories where spiritual energy behaved according to rules no cultivator could reliably predict.
Most merchants avoided it.
Not all of them believed the stories about missing travelers. Some simply understood that, after the Convergence, there was little profit in taking a road that might cease to exist halfway through a journey.
Han Feng understood their caution.
The world had become unpredictable enough to turn an ordinary decision into a death sentence. A mountain that contained spiritual stone veins one day might be completely empty the next. A defensive formation that had functioned for decades could fail without warning. Even cultivation techniques once considered safe could produce unexpected reactions in regions where the laws of two universes overlapped.
Most cultivators responded by gathering more resources, strengthening their formations, or relying on superior force.
Han Feng preferred to understand the ground beneath his feet before committing himself to it.
During the first day of travel, he kept away from the exposed sections of the old road. He followed secondary trails, crossed a shallow stream, and avoided three groups of travelers heading toward the central region. There was no reason to join them. Every unnecessary conversation created another opportunity for someone to remember his face, his clothing, or the direction in which he had gone.
The metal token, the copied documents, and the stone tablet remained in separate compartments of his spatial pouch. He had wrapped each object in layers of insulating cloth and kept them apart with simple concealment seals.
The precautions were not excessive.
Since leaving Broken Bridge, he had begun to suspect that certain objects reacted not only to spiritual energy but also to the presence of other anomalous materials. Until he understood the conditions governing those reactions, keeping them together would be an unnecessary gamble.
By dusk, he reached the ruins of the old trading post.
Two walls remained standing. The roof had collapsed, and a stone pillar covered in weathered inscriptions leaned against the edge of the structure. Beyond it, the road narrowed between two steep slopes. A series of stone markers continued northward, identifying the old transportation route.
Several had toppled.
Others had been shattered by impacts that showed no signs of having occurred recently.
Han Feng stopped beside the leaning pillar.
The inscriptions were mostly illegible, but a sequence of vertical marks caught his attention. Their arrangement resembled the symbols engraved on the metal token, though the correspondence was far from exact.
He removed the token and held it at a distance from the stone.
Then he waited.
Nothing happened.
Han Feng returned it to his pouch.
He had not expected a reaction merely because two objects shared a similar pattern. If the symbols belonged to a common system, they might represent positions, categories, or administrative records rather than a mechanism.
A resemblance was a reason to investigate, not proof of a connection.
Before moving on, he examined the surrounding ground.
Old wheel tracks crossed the remains of the road. Beneath them were newer footprints, some partially obscured by loose soil. At least four people had passed through recently, perhaps five. Two sets of prints were irregular, as though their owners had been carrying heavy objects or favoring injured legs.
All of them headed north.
Han Feng searched for signs of a return journey.
He found none.
That did not mean the travelers had disappeared. They might have taken another route or left the road entirely. Nevertheless, the absence of returning tracks suggested that they had entered the same region the Council had quietly removed from its maps.
He crouched beside the clearest footprint.
The heel had sunk unusually deep into the soil, while the toes had left only a shallow impression.
The traveler had been carrying weight.
A great deal of it.
Han Feng followed the tracks for several dozen paces before stopping.
There was something else.
Near the edge of the road, a narrow strip of disturbed earth crossed the footprints at an angle. It was too straight to have been produced by an animal and too shallow to be a wheel track.
Someone had dragged a heavy object across the ground.
The drag marks ended beside a large stone marker.
They did not continue beyond it.
Han Feng examined the marker from a distance.
For a moment, he considered approaching. Then he noticed that the grass around its base had grown in an unusual pattern, with several blades leaning away from the stone despite the absence of wind.
He withdrew.
Whatever had happened here, he had no reason to investigate it without preparation.
He resumed his journey only after nightfall.
The first anomaly appeared shortly after midnight.
Han Feng was crossing a narrow passage between two rock faces when the spiritual energy ahead became unnaturally concentrated. It formed a thin band across the path, while the surrounding area remained almost completely depleted.
He stopped several paces away.
There was no visible barrier.
No recognizable formation.
No obvious source of the disturbance.
Han Feng picked up a small stone and tossed it across the path.
It fell normally.
He waited several breaths, then selected another pebble. This time, he attached a thread of primordial essence to it, creating a faint signature that he could follow with his spiritual sense.
The pebble crossed the band.
The signature vanished.
The stone continued falling and struck the ground beyond it.
Han Feng's expression tightened.
The phenomenon had not stopped the object. It had erased the energy mark attached to it.
He repeated the experiment with a third stone, using a different quantity of primordial essence.
The result was identical.
The effect appeared to be selective. It did not erase physical matter or halt movement. It interfered with the energetic trace, removing the information Han Feng would ordinarily use to track an object after it passed through the affected space.
That was more troublesome than a simple barrier.
A barrier announced its presence by preventing passage. This phenomenon allowed passage while concealing what had crossed.
Han Feng did not attempt to test its limits.
He climbed along the rocky slope and found a longer route around the affected section. The detour cost him nearly an hour, but he reached the other side without exposing himself to the anomaly.
Beyond the passage, he discovered an abandoned campsite.
Four water containers lay beside a cold fire pit. Two blankets had been left on the ground, and a toolbox rested against a rock. Nothing appeared to have been stolen. The arrangement suggested that the occupants had intended to return.
Yet the marks in the soil told a different story.
Several footprints overlapped near the fire. One set ended abruptly beside a shallow depression, as though its owner had stopped in the middle of a step. Another pair led toward the northern edge of the camp, where the soil was undisturbed beyond a single line.
Han Feng approached the toolbox.
Inside were ordinary tools, several broken measuring instruments, and a folded piece of cloth bearing the emblem of the Regional Council.
Beneath the cloth lay a torn transportation record.
Four names were partially legible.
The final field contained a short notation:
Transfer for subterranean evaluation.
Han Feng read it twice.
The team might have been the same group he was searching for, or merely another unit sent to investigate the anomalies along the old road. There was not enough information to decide.
He folded the document and stored it separately from the token.
The Council had denied the existence of underground facilities, yet its personnel were clearly operating in this region. Whether the Council itself controlled the operation or had merely dispatched a team to investigate it remained uncertain.
Han Feng did not like either possibility.
He spent the rest of the night inside a narrow crevice between two rocks, checking his surroundings at regular intervals.
No pursuers appeared.
Shortly before dawn, however, the entire valley underwent a strange change.
The spiritual energy withdrew.
It did not gather at a single point or flow in a particular direction. For several seconds, the energy across the valley seemed to retreat simultaneously, leaving the mountains unnaturally still.
Then it returned in a slow wave.
The pressure was barely perceptible, but Han Feng felt it pass through his body.
The Celestial Diagram pulsed once inside his consciousness.
He opened his eyes.
No lines appeared. No images formed. The Diagram offered neither a direction nor an explanation.
It had simply responded.
Han Feng waited for another pulse.
Nothing followed.
He did not force a second reaction.
Whatever had disturbed the valley, the Diagram had recognized a change that Han Feng himself could not yet explain. That was useful information, but it was not an invitation to approach the source blindly.
When the sky brightened, he left the campsite and continued north.
The Observation Post
The observation post appeared shortly after midday.
It stood on a rocky elevation overlooking much of the old road. The main tower had collapsed, but a smaller structure remained intact beside the slope. No banners marked the site. No guards stood outside. The entrance had been blocked by loose stones and dry roots, giving the impression that the building had been abandoned for years.
Han Feng did not approach directly.
From a higher ridge, he surveyed the surrounding terrain.
Three points disturbed the local spiritual currents.
The first lay near the blocked entrance.
The second was behind the smaller structure.
The third sat several dozen meters away beside a boulder that appeared to have been moved recently.
Together, the three points formed an irregular triangle.
Han Feng observed them for nearly twenty minutes.
The arrangement was deliberate.
Someone had established a surveillance formation around the post. It was not designed to attack intruders, at least not directly. Its purpose was more likely to detect approaching cultivators or record disturbances within the surrounding area.
That raised an important question.
If the formation was still active, why had the site been left without visible guards?
There were two possibilities.
The people responsible trusted the formation to warn them of intruders.
Or they wanted visitors to believe the post was abandoned.
Han Feng considered the second possibility more dangerous.
He searched the perimeter until he found a narrow gap between the displaced boulder and the rear wall of the smaller structure. The opening was uncomfortable to pass through, but it allowed him to bypass all three points without crossing the apparent detection boundary.
Before entering, he checked the gap for physical traps.
He found none.
That did not prove the route was safe, but it reduced the number of immediate risks.
Han Feng slipped inside.
The room was nearly empty. A broken table lay on its side, two chairs had collapsed beneath their own weight, and a fallen shelf covered part of the western wall.
The inscriptions here were better preserved than those at the old trading post.
Some indicated directions. Others consisted of groups of vertical lines separated by regular spaces.
Han Feng examined them without touching the stone.
In the lower corner, he discovered a sentence carved in ancient characters. Several sections had been damaged, but the meaning remained mostly intact.
The first boundary separates the path. The second determines who may cross it.
He read the sentence twice.
There was no direct reference to the Convergence, nor any evidence that the builders had known about the collision of the two universes. The words might describe a security system, a passage between regions, or even an ancient transportation mechanism.
Still, the distinction between the first and second boundaries was difficult to ignore.
The phrase matched the circumstances surrounding the missing personnel and the warning Shen Rui had received.
Han Feng moved away from the wall and examined the broken table.
One leg rested on a small metal cylinder.
He retrieved it and opened the casing.
Inside was a folded sheet protected by a thin layer of wax.
The report was recent.
Access Report — Third Attempt
The first boundary remains stable in the absence of spiritual energy. The second does not respond to conventional opening methods. The use of primordial essence produces a reaction in the inner surface but does not cause displacement.
A second note had been added beneath the original text in different ink.
Do not repeat the procedure without authorization. The loss of the three operators remains unexplained.
Han Feng's gaze hardened.
The report confirmed that experiments had been conducted here. More importantly, the researchers had already distinguished between two boundaries.
If the underground facility contained a second door, the first might be nothing more than an outer barrier.
The real obstacle lay beyond it.
He still had no idea what waited on the other side.
He had no intention of discovering it by opening a passage blindly.
Han Feng continued searching the room until he found a staircase concealed behind the fallen shelf. The steps descended into the rock, disappearing into darkness. Cold air drifted upward, carrying the smell of damp stone and old metal.
He examined the sides of the staircase and identified two warning inscriptions.
The stonework was much older than the observation post itself.
The underground entrance had not been constructed when the post was built.
Someone had merely discovered a way to reach it.
Han Feng descended slowly, keeping his primordial essence circulating inside his body rather than allowing it to leak into the surrounding space.
Every ten steps, he stopped to examine the environment.
He found no active defensive mechanisms, but small tool marks covered parts of the walls. Someone had enlarged sections of the passage at different times, suggesting that the underground structure had been explored by more than one group over the years.
After several minutes, the stairs ended at a horizontal corridor.
A stone door stood at the far end.
It was not the black door beneath Seven Lantern Depot. This one had a pale surface crossed by horizontal lines, with no central inscription or visible handle.
Nevertheless, Han Feng recognized a resemblance between the markings on its surface and the symbols recorded in the Threshold Society's documents.
He did not touch it.
Instead, he examined the floor.
Four circular marks had been arranged before the entrance.
Two contained traces of spiritual energy.
One carried the residue of primordial essence.
The last was completely empty, as though whatever energy had once occupied it had been removed.
Han Feng crouched to examine the marks more closely.
The arrangement suggested that the researchers had tested several methods of activation. Their results probably differed depending on the cultivation system employed.
The empty mark was especially troubling.
It might indicate a failed experiment.
Or an outcome the researchers had been unable to record.
Han Feng rose and approached the door without crossing the circular marks.
He removed the metal token and held it several inches from the stone.
For several breaths, nothing happened.
Then one of the horizontal lines dimmed.
A small mark appeared near the center of the door, matching one of the numerical groups engraved on the token.
Han Feng immediately returned the token to his pouch.
The door had recognized it, but it had not opened.
The response was consistent with his earlier conclusion: the token identified an authorized record or access category. It was not a complete key.
He examined the door again and discovered a nearly invisible inscription beside the frame.
EXTERNAL ACCESS CONFIRMED. INTERNAL ACCESS UNCONFIRMED.
Han Feng's expression became colder.
So the token had allowed him to confirm that he possessed the right to reach this point.
It had not granted permission to proceed farther.
Something else was required.
Another object, perhaps. A particular condition. Or the presence of someone who understood the mechanism.
Before he could investigate further, voices sounded from the staircase above.
Han Feng extinguished the faint fluctuations of his aura and withdrew into a recess in the wall.
Two men descended carrying a box of instruments.
One wore the uniform of the Regional Council.
The other wore a gray mantle without insignia.
Han Feng recognized the second man immediately.
The same gray-mantled figure who had appeared at Seven Lantern Depot.
The Council official stopped several paces from the door.
"The readings changed during the night," he reported. "The inner sector registered a response that wasn't present in the previous records."
"Did it come from the outer door?"
"No. From the other side."
The gray-mantled man stopped walking.
"And the personnel?"
"The two researchers are still alive. The formation specialist remains unconscious. We haven't been able to stabilize his energy circulation."
"Stabilization isn't necessary. We only need to keep them alive until the next attempt."
The official hesitated.
"The last attempt caused three operators to disappear. If we repeat the procedure without understanding the reaction, we may lose more people."
"We've already lost enough time."
The gray-mantled man removed a small black fragment from his pocket.
It resembled the fragment Han Feng had seen at Seven Lantern Depot, but this piece bore a vertical line engraved on one face.
He held it near the door.
The stone remained motionless.
Then the horizontal lines darkened one after another, and the central mark appeared again.
The gray-mantled man did not smile.
"It's responding faster."
"Is that good?" the official asked.
"It means the interval is shrinking."
He put the fragment away and stepped back.
"Prepare the next attempt for tomorrow. This time, we'll use both systems simultaneously."
The official's face paled.
"The previous combination nearly destroyed the containment formation."
"Then build a better formation."
The exchange ended there.
The gray-mantled man turned toward the staircase.
"Send the remaining materials before sunset. And make sure no one approaches the outer perimeter without authorization."
"What about the Council's inspectors?"
The man paused.
"Tell them the underground structure is unstable and entry is prohibited."
"They may demand to see the records."
"Then give them the records that don't matter."
The official said nothing more.
The two men climbed the stairs, taking the instrument box with them.
Han Feng remained hidden until their spiritual fluctuations had disappeared completely.
Only then did he allow himself to breathe normally.
The conversation had answered several questions.
The researchers were not merely studying the door. They were deliberately attempting to open it by combining primordial essence and spiritual energy.
Their previous experiment had nearly destroyed the containment formation.
The missing operators might have been victims of that attempt.
And the gray-mantled man seemed more concerned with the shrinking interval between the door's responses than with the safety of anyone involved.
Han Feng had no reason to trust him.
He had even less reason to assume the man fully understood what he was doing.
That last possibility bothered him most.
An ignorant enemy could be dangerous.
An enemy who understood only enough to become confident was often worse.
Han Feng examined the door one final time.
The central inscription had changed subtly. The small mark that appeared when the token was read had shifted a few millimeters to the left.
The difference was almost insignificant.
Yet the structure seemed to have recorded his presence.
He withdrew without touching anything else.
He had found the installation, confirmed the existence of an outer boundary, and learned that the Threshold Society intended to combine two cultivation systems to reach whatever lay beyond the inner barrier.
He also knew that the missing personnel were still alive, though one of them remained unconscious.
It was enough to determine his next move.
He would not remain in the installation until the following morning.
Nor would he rush inside and attempt to rescue the prisoners without understanding the situation. He did not know how many guards were stationed nearby, how the containment formation worked, or what consequences might follow if the experiment was interrupted.
A reckless rescue could kill the very people he intended to save.
Worse, it could trigger the mechanism he was trying to understand.
Han Feng returned to the surface through a different route and emerged behind the smaller structure.
The sun was already sinking behind the mountains.
He climbed to a concealed position overlooking the post and settled between two rocks.
From there, he could observe the entrance without crossing the detection formation.
Before nightfall, two additional groups arrived, carrying formation materials and sealed toolboxes. They did not wear official Council uniforms, but the guards at the perimeter allowed them to pass without questioning their authority.
The operation was larger than Han Feng had expected.
There were enough specialists and instruments to conduct a serious experiment, but not enough personnel to secure the entire surrounding region.
That suggested either confidence in the installation's defenses or a deliberate attempt to keep the operation small.
Han Feng watched the newcomers unload their equipment.
One of them carried a long wooden case marked with the same three curved lines converging toward an empty space.
The symbol of the Threshold Society.
The case was handled with unusual care. Two men carried it, and neither allowed it to touch the ground.
Whatever it contained, it was important enough to receive special treatment.
Han Feng made a mental note of its dimensions and the way the carriers moved. He could not determine what was inside, but he might recognize the case if he encountered it again.
As darkness settled over the mountains, the workers began installing new formations around the entrance.
Han Feng counted seven people directly involved in the preparation, excluding the two men who had arrived earlier.
He could not see the entire perimeter, so the actual number might be higher.
He would need to identify the guard rotations, locate the prisoners' holding area, and find a way to leave without crossing the main entrance.
Only then could he decide whether an intervention was possible.
He had no intention of attacking everyone simply because they belonged to the same organization.
Some were researchers. Some were guards. Some might not even know what the experiment was intended to accomplish.
But he would not allow their ignorance to determine his actions, either.
If the next attempt threatened the surrounding region, he would have to choose between remaining hidden and preventing a disaster he could not yet measure.
For now, observation was the only sensible course.
Han Feng settled deeper into the shadows and slowed his breathing until his presence blended with the natural fluctuations of the mountains.
He waited.
Several hours later, a faint vibration passed through his chest.
The Celestial Diagram had reacted again.
This time, the sensation was different from the single pulse he had felt in the valley. It resembled a brief tug on an invisible thread, as though something far away had pulled against the edge of his consciousness.
Han Feng did not move.
He waited for a second reaction.
Nothing followed.
He could not tell whether the response was connected to the door, the metal token, or the larger disturbance spreading through the regions since the Convergence.
He did not need to decide yet.
The important point was that the installation was not isolated from the rest of the world. Each experiment seemed to produce effects beyond the underground chambers, and nobody inside appeared to understand the full consequences.
Han Feng looked toward the hidden entrance.
Tomorrow morning, the researchers would attempt to open the second door.
He would be ready to observe the result, but he would not let their experiment dictate his actions.
If the situation remained controlled, he would continue gathering information.
If an opportunity arose to free the prisoners without exposing his true capabilities, he would take it.
And if something answered from the other side, he wanted to be far enough away to survive—but close enough to learn what had happened.
He closed his eyes and listened to the night.
For the first time since arriving at the observation post, he considered the possibility that the missing personnel were not merely victims of a failed experiment.
Perhaps one of them had seen something.
Perhaps one of them had understood something.
And perhaps that was why the Society was so determined to keep them alive.
The thought did not change his plan.
It changed his priorities.
Before sunrise, Han Feng would need to find the prisoners.
Not to rescue them blindly, but to determine which of them knew enough to explain what lay beyond the second boundary.
Because if the gray-mantled man was willing to risk another catastrophic experiment just to shorten the interval between the door's responses, then the next attempt was unlikely to be an ordinary test.
It would be an attempt to establish contact.
And contact, Han Feng suspected, was not the same thing as opening a door.
Far beneath the observation post, beyond the pale stone barrier, a dark surface remained motionless.
For an instant, a vertical line appeared across it.
It did not open.
There was no sound, no light, and no detectable movement.
Yet something on the far side seemed to recognize that the mechanism outside was finally approaching a functional state.
The line disappeared.
The second door remained closed.
But for the first time in a very long while, whatever lay beyond it was no longer entirely indifferent.
