He tried to reach the village at the fifth hour of the sixth day.
Not a considered decision. The considered decision had been to waitâfor the cascade, for Dr. Lian's response, for the monitoring infrastructure to extend naturally through the mortal realm until it reached the civilian settlements that didn't have sect ruins to activate. That was the correct decision, and he knew it was correct, and he'd been making it successfully for six hours after sending Gao Jun's contact to the division's relay beacon.
Then the Phase 2 monitoring logs updated, and the eastern ruin's sensor data showed one of the seven captive templates had gone flat.
Not the acute distress markers shiftingânot the physiological signature of someone in crisis or worse pain. Flat. The monitoring sensor's template scan cycling through its twelve-second pattern and returning no formation-frequency output where a template had been before. The pattern that the diagnostic station at Hub Seven-West had taught him to read as the sensor reaching a presence that was no longer there.
The monitoring sensor at the eastern ruin was reporting an empty scan.
Six practitioners remaining. Two collector guards. One empty space where a person had been.
He didn't wait for Gao Jun to analyze the data. He didn't compose a query for Old Ghost. He extended his direct conduit interface along the mortal realm's conduit grid, found the line running nearest to his village's direction, and pushed.
The routing sense worked by following activated conduit lines. He'd learned this in the hubâthe direct conduit interface was not a projectable field, not an omnidirectional sense; it was movement along formation-frequency infrastructure, the same way the Phase 2 diagnostics moved through the grid as organized signal propagation. You followed the lines. You read what was at the end of them.
He pushed past the end of the activated line.
The cascade's leading edge was twenty kilometers from the village. Past that edge, the conduit lines existedâthey'd been there for ten thousand yearsâbut they were dormant. No cascade energy running through them. The formation-frequency medium was present in the lines' crystal-composite structure, but without cascade activation, it carried nothing. It was the difference between a conduit line running at operational specification and a conduit line that was structurally intact but powered down.
He pushed his routing sense into the dormant lines anyway.
The direct conduit interface had been built, over twenty-five days of six-pillar work and three days of single-pillar integration, to interact with formation-frequency mediumânot specifically to require cascade activation for that medium to be accessible. He could feel the dormant lines the way he could feel the activated ones. Not with the clarity that the cascade's energy provided, not with the sensor data and monitoring capability that activated infrastructure carried. A baseline perception. Structural-level contact.
He pushed harder.
The relay node's precision enabled him to extend the routing sense further than the junction node alone had allowed. He knew this. He'd used the extended range to track the Archive's withdrawal, to read Elder Han's team at the southern fallback, to follow the cascade's activation events across the mortal realm's boundary. The precision was real. The range was real.
But range in activated infrastructure and range in dormant infrastructure were different problems, and he knew this too, in the same category of knowledge that he was not applying.
He pushed further. Twenty kilometers. Fifteen. The village would be there if he could reach it.
He felt the template's reserve begin depleting.
The routing sense in dormant conduit lines required direct formation-frequency output from his template to function. Not the self-sustaining connection that activated infrastructure provided, where the cascade's energy ran the grid and the direct conduit interface worked with the running system. This was him generating the signal and pushing it through medium that wasn't amplifying it, the formation-frequency equivalent of shouting down a corridor with no sound reflection, your voice carrying on its own until you ran out of voice.
Ten kilometers from the village. His template's reserve dropped three percentage points. The efficiency metric the single pillar had been tracking as upward-trending began reversing. Not dramaticallyâhis template was still well above functional thresholds. But the consumption was real and the gain was not yet real: no signal had reached the village. No monitoring capability had established in the dormant conduit lines. He was generating a formation-frequency event without accomplishing the goal the event was for.
He pushed.
The signal reached the dormant conduit lines at the village's edgeânot inside the village, not establishing sensor access, but reaching the formation-frequency medium in the ground at the nearest approach point. He could feel the village the way you felt a wall in the dark: presence without detail, boundary without information.
No formation-frequency events in the immediate vicinity. No active templates in the conduit lines' range.
He didn't know if that meant the village was fine.
He didn't know if the conduit lines' dormant range could even distinguish populated settlement from empty terrain. He had structural contact with a wall. The wall had no windows. He was standing in the dark pressing his hands against stone.
The reserve dropped another two points. The routing sense in the dormant lines was becoming harder to maintainâthe formation-frequency output required increasing, the signal degrading as distance and medium resistance compounded.
The single pillar in the workshop chimed.
Not the twelve-second passive scan cycle. An alert tone. Lin Feng had set the alert thresholds based on Hub Seven-West's parameters, and this was the threshold he'd designated for significant template deviation events.
*Template efficiency: 58.7%. Alert: significant deviation from baseline trajectory.*
Fifty-eight point seven. Down from sixty-one point one in seventeen hours. The integration work undone in twenty minutes.
He released the push.
The routing sense snapped back through the conduit grid like a rope releasing tensionânot painful, not structurally damaging, but abrupt in a way that left his direct conduit interface feeling like overworked muscle. He stayed on the floor for a moment, his hands flat on the stone, and let the formation-frequency medium around him settle back to ambient.
Six practitioners remaining in the eastern ruin.
Still no information about the village.
He heard Gao Jun's overlay alert before the analyst spoke. The particular pitch of the monitoring function flagging something significant.
"The Archive," Gao Jun said. His voice was flat in a way that was not the flat of professional delivery. "Monitoring sensorsânorthern sectorâtheir staging position is gone."
Lin Feng extended his routing sense into the conduit grid. The Archive's hybrid formation signatures, which had been stationary at the staging area north of the Barrens for three days, were gone from that position. He tracked through the monitoring sensors, scanning the sector. Found them fifteen kilometers from Hub Fourteen-Northeast and moving south.
Moving toward them.
"The formation-frequency event," Gao Jun said. He wasn't asking. He was stating the sequence, beginning to end, without commentary. "Your push into the dormant conduit lines. The formation-frequency output requiredâit propagated through the grid as a detectable event. The Archive's formation-frequency monitoring capability picked up the source vector." He paused. The rod was not in his hand. "Fifteen kilometers. They're moving at field pace. Four hours."
Four hours.
Lin Feng registered this with the part of him that was always running the assessment: four hours, two possible actions, the hatch's access security, the conduit grid's available routing options. He registered it and put it aside to address what was actually in the space between him and Gao Jun.
"I was wrong," he said. Not hedged. No qualification.
Gao Jun looked at him. Then he picked up the rod from the workbench where he'd set it down and turned it once in his hand.
"Yes," he said. "The timing."
"I should have told you before I attempted it."
"The attempt I would have questioned." The rod's rotation was slow, deliberate, not the analytical spin of processing but something controlled. "The timing I would have told you to rethink. The monitoring data showed one empty signature in the ruin. One." He set the rod down again. "That's a practitioner transferred or lost. Terrible. Not sufficient cause to burn template reserves and reveal our position." He paused. "Why did you do it?"
The question was genuine. Not rhetorical.
Lin Feng considered it with the same precision. The correct analysis: he'd processed the empty scan in the eastern ruin and his routing sense had moved before his assessment had completed. The part of him that ran on assessment had been running the situation for six hours and had reached conclusions it hadn't surfaced to conscious evaluation. When the monitoring data changed, the response had been there before the analysis.
"The village," he said. "I've been running the calculation since day two and the calculation doesn't close. The conduit lines don't reach it. The monitoring data doesn't cover it. There's no way to know what's happening there through the available infrastructure." He met Gao Jun's assessment. "I stopped waiting."
Gao Jun was quiet for a long moment.
"The six-day window is three days now," he said finally. "Possibly two. The Archive is moving, and they have a signal vector." He didn't say: you did this. He didn't say: I told you. He said the operational consequence, stated cleanly, and moved to the communication array. "I'm going to send the updated situation to Dr. Lian. She needs to know the Archive is mobile and has a position."
"Yes."
"And you should let the template recover before we need to move again."
Lin Feng sat down on the diagnostic platform's edge and let the single pillar run its passive scan. The alert threshold read cleared now that he'd stopped the pushâthe deviation had been acute, not structural. His template was recovering already, the reserves climbing back toward the baseline the integration had established. The relay node's processing capacity and the substrate layer's conversion were both intact.
The efficiency was at fifty-nine point two now. Lower than where it had been this morning. Higher than where the Third Devourer had stopped.
In the eastern ruin twenty kilometers southeast of them, six practitioners remained in custody. One had left, one way or another.
And in the village where he'd grown up, at the end of a conduit line he'd failed to readâ
He didn't finish the thought. The answer wasn't in the grid yet. He would know when the cascade provided the means to know, not before, and burning his template to get there faster had bought him nothing.
Old Ghost's presence in the substrate moved through the conduit lines with the patience of someone who had seen this exact mistake made before, by someone else, a very long time ago.
He didn't speak. Lin Feng didn't address him.
Some lessons landed cleaner in silence.
