Chen Bai's relay came in during the integration session, which meant the analyst considered it too urgent to wait.
"Don't stop the session," Wei Long said. Hands on the wall. The Crown at thirty-four-point-two percent, the substrate processing the integration with the smooth efficiency of an exponential curve that was becoming visible in real time. Each session gained slightly more than the last. The mathematics were relentless and beautiful and completely indifferent to everything happening around them.
"I won't need long." Chen Bai's voice carried the particular tension that meant Forty-Seven had delivered something the analyst didn't want to report. "The intelligence from Liu Chen's operation updated overnight. Three intercepts from the Heavenly Spirit Sect's internal communication network, cross-referenced against direct observation from Forty-Seven's asset near the wellspring site."
"Hold for twenty seconds." Yue was counting neural load. Thirty-five. Thirty-six. The peak approaching. He held. The substrate settled. Thirty-six-point-eight. "Done. Go."
"Liu Chen changed his extraction method." Chen Bai's pen was audible. Moving fast. "Previous intelligence indicated a steady siphon from the wellspring, the fold's concentrated output channel. Consistent draw rate. Approximately zero-point-five to one percent health loss per month at the seventeen-percent fold, projected to bring the fold below fifteen percent in seven to nine weeks."
"Previous intelligence. What changed?"
"Forty-Seven's asset observed a modification to the extraction apparatus at the wellspring site eleven days ago. Liu Chen's alchemists installed what the asset describes as a 'pulse concentrator.' The new device doesn't draw continuously. It accumulates the wellspring's output in a reservoir and releases it in concentrated bursts at intervals of approximately six hours."
"Concentrated bursts," Yue repeated. The bond carried her calculation before she spoke. "That's more efficient. A steady siphon loses energy to diffusion along the extraction channel. Concentrated pulses deliver more of the wellspring's output to the target, which means—"
"Which means his spirits are receiving more energy per unit time than the continuous siphon provided." Chen Bai's pen stopped. Resumed. "The stolen spirits' progression toward Mythic threshold has accelerated. Forty-Seven's cultivation assessment, based on the asset's observations of the spirits' resonance output during the latest pulse cycle, places them at approximately six weeks from Mythic. Not eight to ten."
Six weeks. Wei Long disconnected from the integration interface and turned toward the relay.
"The fold."
"The seventeen-percent fold's health has dropped from seventeen percent to sixteen-point-four percent in the eleven days since the pulse concentrator was installed. That's a decline rate of approximately point-zero-five-five percent per day. More than double the previous rate." Chen Bai's pen tapped paper. One sharp sound. "At this rate, the seventeen-percent fold crosses below fifteen percent in approximately twenty-two days."
Twenty-two days. Three weeks. The fifteen-percent threshold where the fold's biological vitality dropped below the level needed to resist lattice propagation. The line where an organ went from healthy enough to fight the crystal to too weak to stop it.
"The lattice growth in the seventeen-percent fold," Wei Long said. "Current rate?"
"Moderate category," Latch's voice came from down the corridor. The elder had been listening. "Three-point-eight percent growth over baseline. Within the range expected for a fold above fifteen percent health. If the fold drops below fifteen, the growth rate will accelerate based on the inverse correlation we've established."
"How fast?"
"Based on the data from the fourteen-percent fold and the three-percent fold, a node that crosses below fifteen percent experiences lattice growth acceleration of approximately three to four times the moderate rate within the first week below threshold. The seventeen-percent fold at fifteen percent health would see lattice growth comparable to the fourteen-percent fold's current rate."
"And the compound effect." Chen Bai's pen resumed. "Liu Chen's drain weakens the fold. The weakened fold loses lattice resistance. The lattice grows faster. The growing lattice consumes fold tissue. The consumed tissue weakens the fold further. Two feedback loops operating simultaneously."
Wei Long pressed his palm against the wall. The fold's heartbeat. The network's topology in his awareness, forty-one nodes scattered through the deep boundary, each one carrying its own lattice burden, its own decline trajectory, its own countdown toward a threshold that meant the difference between manageable and terminal.
"Revised convergence timeline," he said.
"Yes." Chen Bai's voice went flat. The analyst was in full assessment mode, the personal removed, the strategic framework operating without the friction of opinion or emotion. "I've rebuilt the model with the accelerated drain data. Here's what converges and when.
"Week three: The seventeen-percent fold crosses below fifteen percent. Lattice growth accelerates in that node. The fold begins compound decline driven by both the external drain and the internal lattice propagation.
"Week four: The Crown reaches approximately thirty-eight to thirty-nine percent. Short of the forty-percent threshold for lattice clearance. The eleven-percent fold, on reduced conduit frequency, begins losing ground — down to approximately ten-point-eight percent, approaching the twelve-percent stability threshold from above.
"Week five: The Crown reaches forty percent. Lattice clearance capacity achieved. But the seventeen-percent fold is now at approximately thirteen percent and declining, with accelerated lattice growth that selective clearance at fifty percent couldn't address for another four to five weeks. Even if we could reach the node, the fold may be past recovery before we arrive.
"Week six: Liu Chen's spirits reach Mythic threshold. The seventeen-percent fold drops below twelve percent. Terminal compound decline begins. The fold cannot be saved by conduit maintenance because the lattice has grown thick enough to absorb the majority of any energy we send through the pathway."
The relay was quiet. Chen Bai's pen was still. Latch's hands were on the wall. Yue was beside Wei Long, the bond carrying her awareness of every number, every trajectory, every countdown running simultaneously toward the same window of impossibility.
"Week three," Wei Long said. "That's the deadline. Not week six. Week three."
"Week three is when the seventeen-percent fold becomes a lattice-vulnerable node. After that, every day makes the problem harder. The fold weakens, the lattice grows, the compound decline accelerates. By week five, when we reach clearance capacity, the situation at that node may already be unrecoverable."
"What about stopping the drain directly?"
"From here? Nothing. The wellspring is at the seventeen-percent fold's output point. Liu Chen's apparatus is physically installed at the fold's surface, in the mortal realm, where the fold's dimensional boundary intersects with the physical territory that Heavenly Spirit Sect controls. Wei Long cannot influence what happens at that site through the Crown's substrate or the bridge's conduit pathways. The drain is a physical extraction at a physical location." Chen Bai's pen tapped once. "To stop the drain, someone has to go to that fold. Physically. And remove whatever Liu Chen has built."
"I can't travel the network until forty percent."
"You can't travel the network until forty percent. Forty percent is nine days away, based on the accelerating growth curve. Nine days from now, the seventeen-percent fold will be at approximately fifteen-point-five percent. Just above the lattice threshold. Barely."
"So the sequence is: reach forty percent, clear the junction lattice, read the record, and then immediately travel to the seventeen-percent fold before it drops below fifteen."
"The sequence gives you approximately one to two days of margin between reaching the fold and the fold crossing the threshold." Chen Bai's pen moved. Fast. "That assumes the junction clearance and record reading can be completed in less than twenty-four hours. That assumes the bridge pathway from the junction to the seventeen-percent fold is among the fifty-six viable pathways with surviving biological tissue. That assumes transit through the cleared pathway is possible at forty percent capacity."
"Is the pathway viable?"
"Latch?"
The elder's hands moved on the wall. Reading the bridge topology. Tracing the pathway from the junction to the node that Liu Chen was draining.
"The primary pathway from this junction to the seventeen-percent fold passes through two connection points and one intermediate node," Latch said. "The pathway tissue is biologically intact. No crystal replacement. The lattice deposits are conduit-fed, not tissue-replacing. The pathway is among the fifty-six viable routes."
"Can I travel it at forty percent?"
"The watcher confirmed that the bridge was designed for transit. At forty percent, the Crown's substrate has the processing capacity to navigate the pathway architecture. The transit itself is a function of the bridge's original design, not a new capability." Latch paused. "But you have never traveled the network. The transit protocol is something the Crown's architecture handles, but the bearer's physical body must survive the dimensional translation between nodes. You are blind. Your cultivation is disrupted. The transit will place physical stress on a body that is already compromised."
"How much stress?"
"I don't know. No one alive has transited a fold network bridge. The last bearer to do it died twenty-four centuries ago."
Wei Long stood. Walked three paces down the corridor. Turned. Walked back. The fold's tissue absorbing each step, the organism's biological support cushioning the bearer's weight with the same unconscious care it applied to everything.
"When I get to the seventeen-percent fold," he said. "What am I dealing with?"
"Liu Chen's apparatus at the wellspring site," Chen Bai said. "Forty-Seven's asset describes it as a cultivation-grade extraction framework. Alchemical foundation, spirit-enhanced conduits, pulse concentrator added eleven days ago. The apparatus is maintained by a team of four sect alchemists who rotate in twelve-hour shifts. Liu Chen visits the site personally for each pulse cycle to direct his stolen spirits' absorption of the concentrated output."
"Liu Chen. In person."
"Every six hours. He arrives. The pulse concentrator releases the accumulated wellspring energy. His spirits absorb it. He leaves. The cycle repeats." Chen Bai's pen stopped. "If you arrive at the seventeen-percent fold through the bridge network and emerge at the fold's interior architecture, you will be inside the fold. Liu Chen's apparatus is on the fold's surface, at the dimensional boundary. Between you and the apparatus is the fold's entire biological structure. You would need to navigate from the fold's interior to its boundary to reach the wellspring site."
"And then?"
"And then you would be standing at the dimensional boundary of a fold space, blind, with disrupted cultivation, facing an extraction apparatus maintained by four sect alchemists and periodically visited by a cultivator who is mid-seventh to peak-seventh realm and climbing."
"He's climbing because he's feeding from the fold."
"He's climbing because he's feeding from the fold, yes. And his stolen spirits are approaching Mythic threshold, which means they'll be operating at a power level that—" Chen Bai's pen resumed. Slower. "—that exceeds anything you can currently match through the Crown alone."
"The Crown isn't a combat tool."
"The Crown isn't a combat tool. It's a custodial architecture. You're not going there to fight Liu Chen. You're going there to stop the drain." The pen tapped. "But Liu Chen may not see the distinction."
---
Yue was waiting in the junction corridor when the relay closed.
"You're going to do it," she said. Not a question.
"Nine days to forty percent. Clear the junction. Read the record. Travel to the seventeen-percent fold. Stop the drain."
"And the junction clearance takes how long?"
"Latch estimates the clearance itself takes thirty to forty minutes at forty percent capacity. The targeted record reading, using Yun Mei's cyclical encoding to skip to the storage layers, takes hours. Not days."
"So you clear the lattice, read the record, travel the bridge, navigate a fold you've never been to, reach the dimensional boundary, and disable an extraction apparatus defended by sect cultivators. All within a two-day window before the fold drops below the lattice threshold."
"Yes."
Yue was quiet. The bond carried her assessment. Not opposition. Not agreement. The lunar spirit processing operational parameters the way she'd been processing them since the day they fell into the Abyss together, the day she chose to follow a broken cultivator into a place where spirits went to die.
"The drain is killing the fold," she said. "But it's also feeding Liu Chen. Feeding his spirits. When his spirits hit Mythic, he becomes something the sects can't ignore. He becomes a power. And a power built on stolen spirits and an unauthorized extraction from a living organism is a power built on a foundation that we can expose."
"We're not playing sect politics."
"We're not playing sect politics. But Chen Bai's Forty-Seven network is. Zhiqiang's legal team is. The Alliance's institutional framework is." She moved closer. The crescent mark on her forehead carrying a faint silver light that appeared when her processing was intense. "If you go to the seventeen-percent fold and physically stop the drain, Liu Chen loses his power source. His spirits stall short of Mythic. His cultivation plateau is exposed. But you also reveal the Crown's existence to anyone at the wellspring site. Four alchemists. Liu Chen himself. The information goes back to Heavenly Spirit Sect."
"I know."
"You know. And you're going anyway."
"The fold dies if I don't go."
"The fold dies if you don't go." The silver light dimmed. Not gone. Banked. "Then we plan for both. Stop the drain and manage the exposure. Chen Bai starts building the information framework now. Zhiqiang's legal team gets advance notice. The Bureau's assessment already cleared us. We build the institutional cover before you arrive at the wellspring, so that when Liu Chen reports back to the sect, the report lands in a context we've already shaped."
"Nine days."
"Nine days to build a cover story, reach clearance capacity, read a twenty-four-century-old record, and travel through a dimensional network that hasn't been transited in longer than most civilizations have existed." The crescent mark pulsed once. "We've worked with worse timelines."
They hadn't. Both of them knew it. But Yue had said it, and the saying was enough to make the impossible timeline feel like something that could be survived.
"Get Chen Bai back on the relay," Wei Long said. "We're building two plans in parallel. The clearance sequence and the intervention strategy. Everything converges at forty percent."
The fold's heartbeat. Fifty per minute. The network humming in his awareness. Forty-one nodes. Twenty-two days until the seventeen-percent fold crossed the line. Nine days until he could move.
And somewhere in the mortal realm, at the dimensional boundary of a fold he hadn't yet touched, Liu Chen arrived for his six-hour feeding, pressed his stolen spirits against the wellspring's concentrated output, and pulled.
