Chương 127: Chapter 126: The City’s Lungs (1)

Worker Block 9-C began coughing at the same time. Not one apartment or corridor—the entire block. The first cough rolled through the eastern residential stack, folding a man over a heating plate, waking a child with both hands around her throat, and driving an old woman toward an emergency mask whose filter was already wet before she pressed it over her face. The filter inside was already wet. Red condensation spread across the transparent plastic. Then the next building coughed. Then the next.

Within three seconds, thousands of throats contracted in one rhythm. One breath. One cough. Silence. One breath. One cough. Ventilation grilles trembled across Worker Block 9-C. Something inhaled behind them. The air returns opened wider. The block coughed again. This time, the sound entered every emergency channel in Crimeria. Thousands of people. One shared reflex. Bloom-0 learning how to breathe with human lungs. Mara Venn was already inside the block when it happened.

The first synchronized cough struck while she stood over a maintenance console beneath Residential Stack Four. Every pressure line on the screen turned red. Not high pressure, but shared pressure. Separate apartments were no longer drawing air independently. The ventilation trunk had begun treating the entire block as one body. Jin gripped the railing beside her. His damaged leg brace whined as the floor vibrated beneath them.

"That is new." Mara opened the resident channel.

"Niko." Static answered. Then a boy's voice.

"I'm here." The feed resolved. Niko crouched beside a sealed laundry-room door wearing a maintenance respirator too large for his face. The straps crossed behind his head twice to keep it from falling off. Ten years old, too thin, and too calm in the way children became calm after adults failed often enough.

Behind him, residents crowded the corridor in a compressed wall of frightened bodies: a woman carrying a sleeping toddler, an old man dragging an oxygen cylinder on one broken wheel, and two workers striking an emergency shutter with different tools because the official instructions had not told any of them which panel controlled it. None of them knew which panel opened it. Mara stared at the scene.

"You were ordered to stay in the west shelter."

"It locked."

"You were ordered to find an adult."

"I found several." Niko turned the camera toward the workers assaulting the wrong control box.

"They don't know which panel opens it."

"You do not know either."

"I know where you kick it." Jin looked at Mara.

"He has observed your methods."

"He should not have." The block inhaled again. The corridor behind Niko flexed inward. A ventilation grille beside him opened by two centimeters. A child's voice whispered from inside.

"Help me." Niko looked toward it. Mara's voice hardened.

"Do not answer." The voice tried again. Closer.

"Please." Niko backed away. Good; he was frightened. That meant he had not become stupid. Mara drew her pistol and fired into the grille beside her own console. The first shot destroyed the speaker. The second burned through red membrane growing behind it. The borrowed child's voice stopped. Jin looked into the smoke.

"Efficient."

"It was not a child."

"No." Mara returned to Niko's feed.

"Listen carefully. You know the old laundry passage behind Stack Four?"

"The one we used when the public stair flooded?"

"Yes." Mara had taken him through it once during a winter pressure failure. One route and one door. He knew where the passage began and which broken floor plate to avoid, but not where the air moved after the route disappeared behind the wall; local knowledge could keep thirty people alive for one corridor, while engineering determined whether the next door opened into safety or another lung for Bloom-0.

"Get the residents to that passage. Do not open any vent. Do not touch pressure control unless I tell you which one." Niko nodded. The respirator slipped down his nose. He shoved it back into place.

"The laundry door is locked."

"I know." Mara opened the remote control tree. The route did not appear. Officially, it had been sealed eight years earlier. She entered three worker overrides. All failed. Then she used an inspection credential Ren had hidden in the block's local cache. The lock changed from red to yellow. Not open—listening.

"Niko. Service panel to the right of the door."

"I see it."

"Open the cover."

"It has screws."

"Use the flat end of the key in the emergency box." Niko looked toward the wall. The box glass had already been broken.

"Someone took the key." Mara closed her eyes for half a second.

"Check beneath the lower pipe." Niko crouched and found a small maintenance key taped behind it.

"You hid this."

"I prepared for adults." Jin smiled. Niko opened the panel. Three levers waited inside. Yellow. Black. Red.

"Which one?"

"Yellow. Bottom position."

"It won't move."

"Both hands." Niko planted one foot against the wall and pulled. The lever shifted. The laundry door opened thirty centimeters. Enough for a child, not for everyone else.

"Again." Niko pulled until his shoulders shook. One of the workers finally understood and joined him. The door opened. Residents began moving into the abandoned passage. Niko did not lead because he understood the ventilation map. He led because he knew the corridor turned left after the broken dryers and the fourth floor plate always collapsed near the drain. That was enough. Mara's console updated. Stolen content alert: this content belongs on Royal Road. Report any occurrences.

WORKER BLOCK 9-C VENTILATION TRUNK SHARED PRESSURE RESPONSE DETECTED LOCAL CONTROL: DEGRADED EXTERNAL ROOT ACTIVITY: ESCALATING A second order covered the map. Four Level Four seals appeared around the border. LOWER-SECTOR RESPIRATORY CONTAINMENT ORDER SEAL WORKER BLOCK 9-C RESPIRATORY SECTORS ISOLATE DOWNSTREAM FLOOR-NINE RETURN SHAFTS PRESERVE UPPER-FLOOR AIR QUALITY LOCAL LOSSES TO BE CLASSIFIED AS CONTAINMENT CASUALTIES Mara read the final line once. Then again. Jin leaned closer.

"They found a cleaner phrase for murder."

"They usually do." Helena's command channel opened. The commander appeared inside an evacuation lift, Floor Nine airflow on one side of her display and Dorian's mobile route on the other. Seraphine moved behind her beside the stretcher. Dorian remained alive. Critical. Breathing through machines no longer owned by AetherGrid. Helena opened a second channel to Level Four.

"How many civilians remain inside the affected sectors?" A neutral voice answered.

"Current estimates are unreliable."

"Then execution cannot be confirmed."

"The containment order has been approved." Helena opened the cited statute.

"Respiratory Containment Statute Seventeen requires local survivability assessment before permanent isolation."

"Subsection Nine permits emergency override."

"After local command estimates survivability." Silence. The law had not been written to protect workers. It had been written after a previous containment disaster became expensive enough that the dead acquired legal weight. Helena continued.

"No local assessment has been filed."

"Upper-floor air integrity is degrading."

"So is your transmission." The neutral voice hardened.

"You have one hour." Helena looked toward Mara. Not asking. Calculating.

"Understood." She closed the channel. Jin raised an eyebrow.

"You asked for four."

"I bought one."

"You said their transmission was degrading."

"I intend to become difficult to contact." Mara looked at the block map.

"One hour is not enough."

"No." Helena transmitted an authorization.

"Which is why you are no longer requesting permission." LOCAL RESPIRATORY EMERGENCY ACTING MAINTENANCE CHIEF: MARA VENN AUTHORITY: WORKER BLOCK 9-C DURATION: UNTIL INCIDENT RESOLUTION OR FORMAL REMOVAL Mara stared at the title. Her disciplinary wristband flashed beside it. EMPLOYMENT STATUS: PENDING REVIEW Crimeria accepted both statements without recognizing contradiction. Jin smiled.

"Chief."

"Do not."

"Chief."

"I will place you inside the balancing chamber."

"That sounds like poor personnel retention." Mara signed the authorization. The block map opened completely. Official routes appeared first. Then the illegal ones. The full map exposed bypasses workers had built when public systems failed, hidden valves, shared oxygen lines, and maintenance gaps too narrow for inspection drones, turning years of survival disguised as code violations into the only infrastructure Mara could trust while Level Four prepared to seal the official routes.

Years of survival had been disguised as code violations.

"Niko."

"Here."

"I am releasing Stack Five and Six cross-doors. Keep people moving. Do not stop for belongings." A lock turned green on his side.

"That door?"

"Yes." He pulled it open.

"Stack Seven is not responding."

"Leave it to me." Mara bypassed the lock through a local pressure sensor. The door opened. Niko moved residents through. Then his camera caught an emergency shutter fused halfway down. People were trapped beyond it.

"Niko, stop."

"There are people there."

"How many?"

"Seven. Maybe eight."

"Do not crawl under." A small hand reached through from the other side. Niko froze. The child beyond the shutter was younger than him. Mara saw his face change.

"Niko."

"I can fit."

"No."

"The adults can't."

"No." The block coughed. The shutter dropped another centimeter. Niko crouched anyway. Jin leaned toward the feed.

"Kid." Niko stopped. Jin's voice was not gentle. That made it easier to trust.

"You go under that door, Mara saves you before she saves them." Niko looked at the trapped residents. Then back at the camera. Mara spoke.

"Yellow side panel. Broken seal." Niko found it.

"Three handles."

"Center one. Pull down. Do not touch the red handle."

"Why?"

"It drops the shutter." Niko moved both hands to the center handle. The trapped adults reached through and helped from the other side. Together, they pulled. The shutter rose ten centimeters. Enough. Residents crawled beneath. Niko counted them. One. Two. Three. The ventilation grille above them began speaking. A tired voice. Amused. Almost familiar.

"Late again." Jin stopped breathing. The voice was close to Ren's. Not exact—too clean. Ren had spoken through damaged masks and bad microphones. The imitation preserved rhythm while removing the lungs that had made it his. The vent continued.

"Jin." Jin's hand tightened around the storage core. Mara watched his face empty. Bloom had not read Jin's memories or recovered Ren from the dead; it had reached old worker terminals, found a shift recording, matched the voice to the storage core beside him, and selected a phrase calculated to make one injured man stop moving while residents remained beneath a collapsing shutter.

"You always arrive after the pressure drops." A real memory crossed Jin's expression. Niko shouted through the feed.

"The shutter is falling!" Jin looked at the speaker. Then at the residents crawling under the door. The imitation tried again.

"You can still find me." Jin turned away.

"That is not him." Mara did not answer. She did not need to.

"Stack Eight first," Jin said. The vent called his name again. He did not look back. The storage core recognized a route already preserved inside Ren's final maintenance report. Three turns beneath Stack Seven. One descent to a circular pressure room beside the original ventilation trunk. Mara recognized the notation.

"Balancing chamber."

"Still functional?"

"It was decommissioned after the collapse."

"That was not my question."

"No."

"Ren thought it was." A warning appeared. MANUAL PRESSURE EQUALIZATION TWO-OPERATOR CONTROL NO REMOTE ACCESS DO NOT OPEN UNDER POPULATED AIR LOAD Mara looked at the block coughing around them.

"Today is poorly suited to instructions." They descended through a shaft barely wide enough for shoulders. Jin went first. His brace struck every third rung. Mara followed while coordinating six channels. Niko remained in the laundry spine. He did not operate the block. He counted residents, kept them away from vents, and repeated Mara's directions when frightened adults stopped listening to a voice from a speaker. The balancing chamber door resisted. Jin and Mara forced the wheel together. Rust broke.

The door opened. The room beyond was empty. That was its purpose. It was a sacrificial volume where dangerous pressure could be dumped before residential expansion buried the original design beneath thousands of apartments, leaving the chamber physically intact but administratively forgotten until the people living above it needed the old emptiness more than the city needed another sealed record. Three valves surrounded a central pressure column. The first isolated Worker Block from the old root.

The second opened the empty chamber. The third vented residual pressure into a dead maintenance stack. All three required simultaneous movement because the isolation valve alone would drive pressure backward, the balancing chamber alone would fill without disconnecting the residents, and the dead-stack release alone would open a route Bloom could use without surrendering the lungs it already held. Mara studied the controls.

"Two operators."

"Three valves."

"One person can hold two."

"No."

"That was not a question."

"You are not holding main isolation and balancing release together."

"I am Acting Maintenance Chief."

"You have been Chief for eight minutes."

"Seven."

"Limited experience." Mara looked at him. Jin connected the storage core to the local reader. The route fragment authenticated. No intelligence or ghost—only maintenance work recognizing maintenance work. A hidden linkage opened between the first two valves. Mara stared.

"Mechanical delay."

"Seventeen seconds."

"He modified the chamber."

"He made three-person work possible for two people."

"He violated every pressure standard."

"He was a worker." The block inhaled. The central column turned red. Bloom membrane spread across the pipes. Jin gripped the isolation valve. Mara took the balancing release.

"Niko."

"Here."

"How many remain in the laundry spine?"

"Thirty-two."

"Get them behind the pressure door."

"Which one?"

"The gray door with the blue stripe."

"There are two."

"The one without the window." Niko found it. He did not know why it was safer. He did not need to. He moved the residents through and pulled the manual latch.

"Closed."

"Stay there." A child began crying behind him. Niko sat beside the door. He did not say everything would be fine. He was ten, not dishonest.

"Mara knows the air." Inside the chamber, Bloom used Ren's voice again.

"Late." Jin closed his eyes. Then opened them.

"No." He pulled the first valve. Mara opened the balancing chamber. The mechanical delay engaged. Seventeen seconds. The block pressure fought back. Jin's brace bent. Metal screamed around his knee.

"Hold."

"I am." Five seconds. Red membrane burst from the column. Mara fired into it. The rounds slowed tissue but not pressure. Nine seconds. The false voice whispered.

"You left me." Jin's hands tightened. Twelve. His brace split at the lower hinge. His leg folded. He caught the valve with both hands before it reversed. Mara reached toward him.

"Do not."

"If it closes—""Open the third." Fourteen. Mara moved. The dead-stack release resisted. She struck the lock with her pistol. Nothing. Fifteen. She fired into the latch. The third valve released. Sixteen. Jin lost his footing. The isolation handle began turning backward. Mara threw herself across the gap and caught it with one hand. Seventeen. The linkage completed.

The Worker Block ventilation trunk disconnected from the root at the exact moment Jin's broken brace ceased supporting his leg, Mara's grip began slipping from the isolation handle, and the red membrane inside the pressure column stretched toward the only empty volume left in the system. Pressure entered the empty chamber. Every red membrane stretched toward the sacrificial volume. Then the dead maintenance stack opened. Bloom pressure tore away from the residential sectors. Not destroyed, but redirected.

Trapped behind manual systems with no living lungs attached. Worker Block 9-C coughed once more. Thousands of people. One rhythm. Then the rhythm broke. A child coughed twice. An old man wheezed. Someone sobbed inside a respirator. A woman shouted for her husband. Different sounds from different bodies, all alive. Mara's console updated. WORKER BLOCK 9-C PRESSURE ROOT: ISOLATED RESIDENTIAL AIR LOAD: INDEPENDENT BLOOM PRESSURE: CONTAINED IN SACRIFICIAL CHAMBER Jin released the valve. His brace collapsed. He fell.

Mara caught him beneath one arm. He looked at her emergency title.

"Chief." She pulled him upright.

"Say it again and I revoke your access to language."

"Niko first?" Mara opened the boy's feed. He sat beside the sealed pressure door. Thirty-two residents waited behind him. Still breathing. Niko looked at Mara.

"Did we fix it?"

"Not all of it."

"The air?"

"For now." He nodded. That was enough. Behind Mara and Jin, something inside the balancing chamber used Ren's voice one final time.

"Jin." He stopped. Mara waited. Jin removed the storage core from the reader. The golden route vanished. The chamber went silent. Jin climbed. He did not answer the borrowed voice again. Above them, Worker Block 9-C breathed through thousands of separate lungs. The city map updated. One pressure root darkened. Three remained. Then the medical return line turned red.
