The cascade reached Linfeng County at dawn on the fifth day.
Lin Feng felt it before the Phase 2 diagnostics registered it. His direct conduit sense extended through Hub Fourteen-Northeast's supply line, through the main distribution network, through the leading edge of the cascade's propagation, and thenâwith the particular quality of a perception opening rather than wideningâinto the mortal realm's buried infrastructure. Former-sect ruins, the conduit lines integrated into their pre-Abandonment construction, coming alive as the cascade's energy reached them. Not all at once. A progression: the closest ruins first, then the ones further along the distribution paths, the activation events appearing in the Phase 2 diagnostic logs like lights turning on in a dark building, room by room.
He lay on the stone floor and read the mortal realm through the grid.
The monitoring sensors in the former-sect ruins began reporting in the first ten minutes of activation. Environmental data first: temperature, atmospheric formation-frequency density, structural integrity reports from the ruin buildings themselves. Then practitioner data: the sensors' template-scanning capability activating for the first time in ten thousand years, beginning their twelve-second cycles, flagging every formation-frequency-active presence within their range.
Linfeng County had twelve former-sect ruins within the network's current reach. Eleven were unoccupied, their monitoring sensors reporting empty atmospheric data and the background formation-frequency levels of terrain that had once been cultivation-active and still carried the residue. The twelfth ruinâa mid-tier sect location in the county's eastern region, twenty kilometers from the village where Lin Feng had grown upâwas occupied.
Seven template signatures. Active formation-frequency output. Not background residue.
He read the signatures through the monitoring infrastructure with the precision the relay node's processing capability provided. Seven practitioners, their templates ranging from early-training formation to mid-level cultivation. Mortal-realm practitioners, not the hybrid-architecture templates of Cai's Archive. These were people who had been cultivating before their capture, their templates intact but carrying the formation-frequency markers of practitioners under significant sustained stress. The physiological signature that the monitoring sensors classified as "acute distress: present, prolonged."
And around the seven practitioners' templates, he read the monitoring sensors' structural data for the ruin's occupied building: sealed entry points, formation-frequency barriers in the wall architectureâmakeshift, not pre-Abandonment construction, the kind of barrier that someone with mid-level cultivation ability had assembled from available materialsâand two additional template signatures that he recognized by their hybrid formation-frequency architecture.
Collectors.
Two of Cai Zhong's practitioners guarding seven captives in a former-sect ruin twenty kilometers from Lin Feng's home village.
He lay on the floor and let the grid carry this information into his direct conduit sense for a long time. Long enough that Gao Jun, who had been running his own overlay analysis and presumably monitoring Lin Feng's formation-frequency output as he did during high-information periods, crossed the workshop and crouched two meters away.
"What do you have?" the analyst asked. His voice was the precise professional register that meant he was already preparing for complex information.
Lin Feng reported it flatly: the ruin's location, the seven captive practitioners, the two collector guards, the distance from his village.
Gao Jun ran the numbers on his overlay. His formation-frequency output increasedâthe analytical processing of someone integrating multiple data streams and probability models simultaneously. Then: "The division's intelligence placed Cai's active collection at three former-sect locations in the Linfeng region. This is one of them. The other two are further eastâoutside your current routing range, probably beyond the cascade's current reach." He paused. "Seven practitioners in this location. If the other two collection points are running at similar capacity, Cai has twenty to twenty-five practitioners in custody in Linfeng County right now."
"The village."
"Outside my routing range. Twenty kilometers from the ruin, southeast." He felt the conduit grid with his direct interface, tracing the activation events, finding where the cascade's reach ended. The conduit lines ran as far as the former-sect ruins. The villageâa civilian settlement with no sect history, no cultivation architecture, no pre-Abandonment infrastructure beneath its streetsâwas off the grid. "I can't read it directly."
"What can you read?"
"The monitoring sensors' atmospheric data for the region. The formation-frequency background levels." He extended his routing sense along the conduit line running nearest to the village's direction, reading the environmental data as far as the line reached. "Nothing anomalous in the background levels. No acute practitioner activity in the region's atmospheric data."
No acute activity meant no large-scale formation-frequency event in the village. A collection operationâCai's practitioners moving through civilian settlements, taking people with latent formation-frequency capabilityâwas a low-profile event. It wouldn't register in atmospheric data. It would register in the absence of certain template signatures from places where those templates had previously been.
Which he couldn't read without direct sensor access to the village itself.
"The conduit infrastructure doesn't extend into civilian settlements," he said.
"No. It runs to sect ruins, to former cultivation sites, to the locations the pre-Abandonment network was built around." Gao Jun's overlay was running a mapping analysis. "If you want to read what's happening in the village, you'd need the cascade to advance another twenty kilometers into territory with no existing infrastructure to activate. Based on the current propagation rate, that'sâ"
"Six to eight days."
"Minimum."
Six to eight days. And Cai's collection cycle was ten days. And the last division intelligence update was three weeks ago. Which meant Cai's operation could be anywhere in the cycleâcould have run a collection through the village two weeks ago, or one week ago, or could be running one now.
Lin Feng's hands were flat on the stone floor. His breathing was even. He was aware of these facts about his own body as external data, the monitoring sense applied inward, the way he sometimes read his template's formation-frequency status as if it belonged to someone else.
"Gao Jun."
"Yes."
"The seven practitioners in the eastern ruin." He organized the request before speaking it. "Can the division's field team reach that location from the western settlement?"
The analyst ran the calculation. "At field pace, factoring for terrain and the Archive's current northern positionâtwelve hours. A division extraction team could reach the ruin in twelve hours." He paused. "Dr. Lian has been waiting for the meeting we scheduled for today. Her field team is at the western settlement with full operational capability."
"Contact her. Send the ruin's location, the captive count, the guard assessment. Ask if she can move a team immediately."
"If I send that data, she'll know we have conduit-grid access to the mortal realm's monitoring infrastructure." The rod was very still. "The division has been trying to establish that access for eleven years. Your direct conduit interface gives you what three centuries of division research hasn't managed to build."
"She'll know we have it regardless when she arrives and sees what my routing sense can do."
"True." A pause. "Sending the meeting today instead of in three days?"
"She can have her meeting while her team is moving toward the ruin." Lin Feng stood. His legs had the slight stiffness of three days spent mostly on stone floors, and he worked it out in a few slow circuits of the workshop. "If she's going to be a resource, I need to understand what she'll actually do when the time to act is now. Not what she'll propose when we're discussing it in comfortable conditions."
Gao Jun looked at him for a moment. The analytical mask had its careful qualityâthe one Lin Feng had learned to read as the analyst running an assessment he hadn't been asked for, deciding whether to voice it.
"You're testing her," Gao Jun said.
"I'm observing whether what she offers matches what she does." Lin Feng stopped at the workbench. "Same thing."
The rod in Gao Jun's hand rotated once, slowly, then resumed its steady spin. He opened the communication array and began composing the contact to Dr. Lian's relay beacon.
Lin Feng returned to the direct conduit interface and stayed with the seven template signatures in the eastern ruin. The monitoring sensors read them in their twelve-second cycles: the acute distress markers, the intact but stressed formations, the two collector guards with their hybrid architecture creating interference in the scan data around the barrier walls.
Seven people. Twenty kilometers from his village.
He couldn't read the village. The conduit lines didn't run there. He had no way to know if the village was fine or not fine or somewhere in the vast uncertain space between those two states.
The grid moved through his direct conduit sense, the cascade carrying the energy of ten thousand years of accumulated potential, waking the mortal realm's buried bones one ruin at a time.
Old Ghost was in the substrate somewhere. Lin Feng didn't reach for him.
Lin Feng thought about the Third Devourer stopping at fifty-nine percent because they'd seen what the second consumption required: the habit of management becoming optional.
He was not having that problem. The habit of management was running at full output, assessing options, modeling timelines, calculating distances and capacities and decision trees.
Forty-eight hours until Dr. Lian could move a team to the eastern ruin. Forty-eight hours during which anything could happen in the village that the conduit grid couldn't read.
He sat with the not-knowing and found it harder than anything the diagnostic station had asked of him.
