Latch finished the survey at twenty-two-hundred. Seven hours of individual node readings, six nodes per hour, his hands never leaving the wall except to wipe the sweat that kept gathering on his palms. The elder's bond had reached through the network topology to each of the forty-one folds in sequence, measuring lattice fragment dimensions against the baseline he'd established six days ago with the same methodical patience that three thousand years of biological expertise required.
Wei Long was in the junction corridor when the elder pulled his hands from the tissue for the last time and sat down on the floor. Not carefully. Not with the measured descent of a cultivator conserving energy. He just sat, the way someone sits when standing has stopped being worth the effort.
"How bad?" Wei Long asked.
Latch wiped his hands on his robe. Looked at the wall he'd been reading for seven hours. Then looked at Wei Long with an expression the bearer had never seen on the elder's face before.
"Twenty-three."
"Twenty-three nodes with lattice growth."
"Twenty-three of forty-one nodes showing measurable increases in lattice fragment dimensions since the baseline survey." Latch's voice was flat. Technical. The biological precision that was his default mode, now carrying information that the precision could not soften. "Growth rates vary by a factor of twelve between the fastest and slowest. No two nodes are progressing at the same rate."
"Chen Bai."
"Recording." The relay was open. The analyst had been listening since Latch started the final batch of readings three hours ago. His pen was already moving. "Full data set, Latch. Every node. Growth rates, current lattice dimensions, fold health percentages, whatever correlation variables you measured."
Latch closed his eyes. Recited from memory the way a physician recites a patient's chart — organized by severity, starting with the worst.
"Node seventeen. The three-percent fold. Lattice fragment growth rate: nine-point-four percent increase over six-day baseline. Current fragment dimensions exceed the fourteen-percent fold's growth, which I identified as the initial anomaly yesterday. The three-percent fold's lattice is growing faster than any other node in the network."
"The weakest fold has the fastest growth."
"The weakest fold has the least biological resistance." Latch opened his eyes. "The pattern holds across the data set. I'll give you the full numbers, but the correlation is clear enough to state now: lattice growth rate is inversely proportional to fold health. The weaker the organism, the faster the lattice propagates through its architecture."
He recited the numbers. Node by node. Chen Bai's pen scratched through the relay, the analyst building the data table in real time, the organized mind that ran the Forty-Seven network now processing biological survey data with the same systematic intensity it applied to intelligence intercepts.
The healthy nodes — the seven folds above twenty percent that had been the network's backbone — showed minimal growth. Fractions of a percent. Background noise, Latch called it. The fold's biological vitality at those health levels generated enough metabolic activity to resist the lattice's self-propagation. Like a strong immune system fighting off an infection that the organism couldn't technically recognize as hostile. The body didn't know the lattice was dangerous, but the body's general health kept it in check anyway.
The moderate nodes — the majority, clustered between fifteen and twenty percent — showed growth rates between one and four percent over the baseline period. Slow enough that the lattice wasn't an immediate threat. Fast enough that Latch's jaw tightened as he read each number.
The weak nodes. Below fifteen percent. Twelve of them, including the three critical folds that had been the network's primary concern since Wei Long first understood what the numbers meant.
"The eleven-percent fold," Chen Bai said. "The one we're actively maintaining."
"Growth rate: five-point-one percent." Latch's voice didn't change. The number was the number. "Higher than the moderate nodes. Lower than the three-percent and fourteen-percent folds. The daily conduits are improving the fold's health, which is improving its resistance to lattice propagation, but the fold started weak enough that the lattice had already established significant presence before the conduits began."
"The conduits are helping."
"The conduits are helping the fold. They are also, indirectly, slowing the lattice. But they are not stopping it. At the eleven-percent fold's current health and growth trajectory, the lattice propagation will outpace the biological recovery in approximately four weeks. After that point, the lattice's conversion of fold tissue to crystal exceeds the fold's ability to regenerate, and the node enters terminal decline regardless of conduit maintenance."
Four weeks. The same window. Everything converging on the same point in time, every variable in the system trending toward the same cliff.
"The seventeen-percent fold," Wei Long said. "Liu Chen's drain target."
"Growth rate: three-point-eight percent. Moderate category. But the fold's health is declining due to the external drain, which means its biological resistance is declining. The growth rate six days ago would have been lower. In six more days, it will be higher." Latch paused. "The seventeen-percent fold is on a trajectory to cross below fifteen percent within three weeks if the drain continues. At that point, it enters the vulnerable category and the lattice propagation accelerates."
"Two problems compounding."
"Two problems compounding in the same node, yes. The drain reducing health, the reduced health accelerating lattice growth, the lattice growth consuming tissue that the fold needs to resist the drain. A feedback loop. The seventeen-percent fold is in better condition than the three-percent fold, but its trajectory is worse because the drain is actively pushing it toward the threshold where the lattice takes over."
The relay was quiet except for Chen Bai's pen. The analyst writing, calculating, the numbers building a picture that looked like a network eating itself from the inside out.
"The eighteen remaining nodes without measurable growth," Latch said. "All above nineteen percent health. The lattice fragments in those nodes are present — every node in the network carries lattice material from the original propagation event — but the fragments are not expanding. The fold biology at those health levels generates sufficient metabolic resistance to hold the lattice static."
"Static. Not shrinking."
"Not shrinking. The fold cannot dissolve the lattice. The lattice is Crown-derived. The fold's biology treats Crown-derived material as part of the symbiotic relationship. It can resist expansion through general metabolic health, but it cannot attack the material directly."
"So even the healthy nodes are carrying lattice fragments that will start growing the moment their health drops below the resistance threshold."
"Correct."
Wei Long pressed his hand against the junction wall. The fold's heartbeat. Fifty per minute. The organism that housed him, that healed him, that invested in his biology with the patient optimization of a system designed for exactly this kind of mutualistic partnership. The junction fold was healthy — well above twenty percent, the primary node in the network, the best-maintained organism in the system. Its lattice fragments were dormant.
For now.

"The clearance problem," Chen Bai said through the relay. His pen had stopped. "Walk me through the mechanics."
"The lattice clearance operates through the Crown's resonance at forty percent capacity," Latch said. He'd stood up from the floor and returned to the wall, hands flat, reading the junction's local architecture. "The Crown generates a targeted frequency that dissolves the lattice's crystalline structure. The dissolution propagates outward from the Crown's position through the fold's tissue, breaking down the crystal layer by layer."
"Outward from the Crown's position. Meaning outward from wherever Wei Long is standing."
"Outward from the Crown's substrate interface point, yes. The dissolution requires direct substrate contact. The Crown's resonance frequency must reach the lattice material through the fold's biological tissue, and the tissue must be connected to the Crown's substrate in real time."
"Can you run the clearance through the conduit pathway?" Wei Long asked. "The same way we run maintenance to the eleven-percent fold?"
Latch was quiet for a long time. Reading. The elder's hands moving across the wall in slow patterns, his bond testing the substrate's architecture, measuring the conduit pathway's properties against the requirements of a clearance operation.
"No."
One word. Wei Long waited for the rest.
"The conduit pathway transmits the watcher's maintenance energy. Maintenance energy is a broad-spectrum output — general biological support, the equivalent of nutrients and oxygen delivered through the bloodstream. The lattice dissolution requires a specific resonance frequency generated by the Crown's substrate at forty-percent resolution. That frequency is too precise, too narrow-band, to survive transmission through the conduit pathway. The pathway degrades the signal. By the time the dissolution frequency reached the eleven-percent fold through the conduit, it would be garbled beyond operational use." Latch pulled one hand from the wall. "The conduit is a garden hose. The clearance requires a scalpel."
"So the clearance only works locally."
"The clearance works where the Crown's substrate can interface directly with the lattice material. Within this junction, where you're standing, the Crown's substrate has direct contact with the fold's tissue and through it, with the lattice fragments embedded in that tissue. You could clear the lattice from this junction. From this node."
"From this node. Not from the network."
The silence answered before Latch did.
"Each of the twenty-three affected nodes would require the Crown's direct presence. The bearer, physically located at each node, interfacing with each fold's substrate individually, running the dissolution frequency through each organism's local architecture." Latch's hands dropped from the wall. "Twenty-three nodes. Scattered across the deep boundary topology. Connected by bridge pathways that the lattice itself is degrading."
"How far apart are the nodes?"
"The network spans approximately three hundred kilometers of deep boundary topology. The farthest node from this junction is a hundred and forty kilometers through dimensional space that does not follow straight-line geometry."
"Travel time?"
"Through the deep boundary? At current capacity?" Latch looked at him. "You are blind, Wei Long. Your cultivation is disrupted. The Crown gives you dimensional awareness within the fold's substrate, but outside the fold's architecture, in the raw deep boundary between nodes, you would be navigating corrupted dimensional space without sight, without cultivation, with only the Crown's thirty-two percent capacity and whatever the watcher can project beyond the bridge's range."
"So I can't just walk to each node."
"Walking to each node would take weeks. Perhaps months. Through territory that Abaddon has warned is increasingly unstable due to the Spirit Tyrant's approach. And during those weeks or months, the lattice would continue growing in every node you haven't reached yet." Latch sat down again. The same abrupt descent as before. "The clearance is a local operation that must be performed globally. The scope of the task is — it is not what we planned for."
"What did we plan for?"
"We planned for a single clearance event at forty percent. The Crown reaches capacity. You clear the lattice from the bridge. The fold's communication resolves. The network stabilizes." Latch's voice was precise. Not angry. Not frustrated. Precise the way a physician is precise when telling a patient that the diagnosis has changed. "We assumed the lattice was a single problem at a single location. It's not. It's forty-one problems at forty-one locations, and twenty-three of them are getting worse."

Chen Bai's analysis came through the relay at midnight.
"Three options." The analyst's voice carried the particular flatness of someone who had evaluated every available course of action and disliked all of them. "Option one: clear the junction's lattice at forty percent, read the record, and accept that the remaining twenty-two affected nodes will continue to degrade. Focus resources on maintaining the critical folds through conduits while searching for a way to extend the Crown's clearance range."
"Timeline?"
"Junction clearance and reading in fourteen days. Network-wide lattice degradation continues unchecked during that period. The three-percent fold reaches terminal lattice saturation in approximately five to six weeks. The eleven-percent fold in eight to ten weeks, assuming continued conduit maintenance. The seventeen-percent fold in six to eight weeks, depending on Liu Chen's drain rate."
"Option two."
"Delay the junction clearance. Instead, use the time between now and forty percent to develop a method for extending the Crown's dissolution range through the conduit pathway. Latch says it's impossible with current architecture. I'm asking whether the architecture can be modified."
"And if it can't?"
"Then we've wasted fourteen days and the lattice has grown in all twenty-three nodes while we developed nothing." Chen Bai's pen tapped against paper. "Option two has the highest potential reward and the highest risk of total failure."
"Option three."
"Physical travel. You go to each affected node in person. Clear the lattice locally at each one. Start with the most critical nodes — the three-percent fold, the fourteen-percent fold — and work outward."
"Latch said weeks. Months."
"Latch said weeks through the raw deep boundary. But the bridge pathways between nodes are not raw deep boundary. They're the network's own architecture. Maintained. Mapped. Connected." Chen Bai's pen stopped. Then resumed. "The bridge pathways are degraded. The lattice is interfering with them. But they exist. They're traversable. The question is whether the Crown at forty percent can use the bridge pathways as transit corridors rather than just conduit channels."
"Can it?"
"I don't know. Latch doesn't know. The watcher might know, but we haven't asked the right question yet." The relay carried the sound of pages turning. "The bridge was built to connect nodes. It was built for traffic. Before the lattice, before the previous bearer's consumption, the bridge was a functional transit system. Bearers traveled the network. That was part of the Crown's purpose — the custodian visits the nodes, maintains them, ensures their health. The bridge was a road, not just a pipe."
Wei Long pressed both hands against the wall. The fold's heartbeat. The bridge's architecture humming underneath, the pathways that connected forty-one living organisms across three hundred kilometers of deep boundary space. Pathways that had once carried a bearer from node to node. Pathways that the lattice had choked and degraded for twenty-four centuries.
"If the bridge is a road," he said, "the lattice filled it with crystal."
"And if you clear the crystal from this end, the road opens." Chen Bai's pen moved faster. "Clear the junction first. The junction clearance opens the bridge pathways connected to this node. Then travel the cleared pathways to the nearest affected nodes. Clear those. The cleared nodes open pathways to the next ring of nodes. Cascading clearance, outward from the center."
"How long?"
"Depends on travel time between nodes and clearance duration at each one. I can model it once Latch provides bridge pathway distances and the watcher provides transit speed estimates." A pause. "It's still weeks. But it's weeks of active clearance, not weeks of blind travel through hostile space."
Weeks. The convergence window closing around them. The Spirit Tyrant approaching. Liu Chen's drain accelerating. The lattice growing. And now the task that had been a single operation at a single location was a campaign across an entire network.
"We need more information before we choose," Wei Long said. "Latch maps the lattice encoding. Yun Mei assists. The sessions continue. The conduits continue. And tomorrow, I ask the watcher about bridge transit."
"The watcher may not know. The bridge hasn't been used for transit in twenty-four centuries."
"The watcher maintained the bridge for three thousand years before the lattice. If anyone remembers what the road was for, the guardian does."
The relay closed. The corridor went quiet. The fold's heartbeat, steady and patient, the organism that didn't know its own tissue was being converted to crystal, that couldn't fight the process because the process wore the Crown's face.
"Twenty-three nodes," Yue said from beside him. Her voice carried something he couldn't name through the bond. Not worry. Not calculation. Something older. "The previous bearer's last act is still running. Twenty-four centuries later. Their gift and their curse, growing in the same crystal, node by node."
"We'll stop it."
"We'll try to stop it. While reading the record it contains. While the Spirit Tyrant closes in. While Liu Chen drains a fold we can't reach. While Shen hides and the Bureau watches and the lattice grows another layer every day." She was quiet for a moment. "This is a lot of problems for one bearer."
"One bearer and a lunar spirit who counts too well."
She didn't laugh. But the bond carried something that was close.
