The "Survival on the Train" game has bugs, it's really laggy!

The 012 heavy armor forward trolley stopped two meters in front of spray gate 32. The rail pin popped out and engaged the rail surface. The newly cast protective shell sealed half of the front rail, and the anti-slip texture on the bumper was dim under the light.

Three sets of stainless steel spray doors stood side by side above the rails. The door frames were so clean they reflected the headlights, and the spray nozzles were densely packed downwards, their surfaces abnormally dry, without a trace of water. White mist seeped from the edges of the door frames, creeping down the stainless steel.

After the aluminum seal on the frostbite repair gel in the 013 medicine cabinet popped open, the protruding 009 steel plate was clamped in Wang Hu's pliers. Four words: Don't let the spray touch the blood.

Wang Hu flipped the steel sheet over. There were no markings on the back. He inserted the steel sheet into the storage slot on the outer beam, placing it alongside the other 009 road signs.

Tang Lan had already moved. She pulled out a sterile dressing pack from the bottom of the medicine cabinet, tore it open, and folded the gauze into narrow strips. The two able-bodied survivors beside her watched her but didn't ask why.

"Flip the wristband over, buckle facing inward." Tang Lan wrapped a strip of gauze around the first wounded soldier's left wrist, covering the metal buckle of the blue wristband. "Cover the IV drip inlet. Replace all bloodstained bandages with new dressings to cover them up."

Her movements were fast, but her hands were steady. The second wounded soldier had dried bloodstains on his chest bandage. She used adhesive tape to attach clean gauze to the outside of the bandage, sealing every spot where blood had seeped through.

No one in carriage 013 mentioned transferring the wounded anymore. The person who had previously said "transfer the seriously wounded first" lowered his head, rolled up his cuffs to reveal his wristband, and then flipped it over to fasten it.

From direction 005, the voice of a young survivor came through: "Tail boom 16.4. Cabinets normal. Seals untouched."

Wang Hu jumped down from the outer beam carrying a bag of lime, walked to the 012 protective shell, and sprinkled a handful of lime powder directly below the sprinkler door.

The white powder fell onto the rail surface but wasn't absorbed. However, the powder didn't disperse properly directly below the spray head—the moisture stuck it together into thin lines, creating winding white streaks along the metal surface.

Wang Hu squatted down and tapped the bottom beam of the sprinkler door with a wrench. *Clang.* The echo was muffled, without any interlayer. He changed position and tapped the base of the right-side pillar of the door frame. *Clang.* This time, the echo had thin-walled resonance, indicating a cavity inside.

"The door frame is empty. The pipes are inside the pillar."

A small scanning light extends from the roof of the vehicle, scanning the spray door structure with low power. Data jumps onto the main screen layer by layer.

"Spray fluid composition analysis complete." Xiao Huo paused for a moment. "It's not a strong acid. It's not a corrosive agent."

"What is it?" Su Yuan asked.

"A slightly conductive purifier. pH 7.2, close to neutral. The solute contains silver ion complexes and ferromagnetic tracking particles."

The small torch displays the molecular structure diagram on the right side of the main screen. "It has no effect when it exists alone. Upon contact with iron in the blood, the silver ion complex forms a conductive film. This film forms a complete identification circuit along the blood, the wristband metal buckle, and the metallic magnetic layer in the 005 protective compartment seam."

Wang Hu stood up and brushed the lime off his hands. "It doesn't burn people. It puts labels on people."

In the control room of Base 04, the technician switched the spray fluid composition analysis to full-channel sharing. The veteran engineer stared at the molecular formula of the silver ion complex for three seconds, then tapped the screen with his finger.

"This thing becomes electrified when it comes into contact with blood. Once electrified, it reads all the data from the wristband and the blood oxygen information."

"Not only that." The technician overlaid the simulation diagram of the conduction path. "Once the loop is formed, the shielding layer of the 005 compartment will also be penetrated. The conductive film will seep in along the gaps in the seals."

The radio came on. The old cassette tape's voice was dry and hoarse, with incorrect phrasing.

"Disinfection line No. 32 activated. Epidemic prevention procedures implemented."

"The 013 casualty ward will be disinfected first by spraying."

"005 The tail anchor compartment entered the contaminated drain tank."

"The mobile refining furnace enters the equipment cleaning track."

It paused for a moment.

"Access will be granted after the traffic diversion is completed."

Three rows of guide wheels rise from the ground behind the spray door. The rubber surface is aged and cracked, but the rolling mechanism is normal. The first row of guide wheels is pressed against the left side of the 012 hull, the second row is aligned with the third connecting section, and the third row is against the right side of the 005 enclosed hull.

The entire column was pushed simultaneously from three directions. The first set of nozzles began pre-pressurization, and a faint sound of liquid flowing could be heard in the pipes. A red countdown timer lit up above the sprinkler gate. Sixty seconds.

In carriage 013, several wounded soldiers who had just received injections to stop the bleeding heard the order to "prioritize disinfection of the casualty ward." One wounded soldier with a splint on his leg looked up at Tang Lan. Another wounded soldier with a chest brace gripped the edge of the bed again.

Tang Lan didn't look at them. Her right hand rested on the gun handle, the muzzle pressed against the handrail next to the grappling hook cover.

In the control room of Base 04, the technician stared at the spray solution composition table, his mouth opening and closing but no words coming out. Someone on the lower levels of the Bonebreaker channel muttered a curse.

"This time the materials are genuine. The process also looks authentic."

No one responded. Everyone was weighed down by the words "Don't touch the blood." The medicine was real, the cabinet was real, the spray solution wasn't acid, and the procedure was for epidemic prevention—but 009's steel plate said not to let the spray touch the blood, and Xiao Huo said that touching the blood would create an identification loop.

Su Yuan's vehicle speed was zero. He stared at the direction of force applied by the three rows of guide wheels and the dust reaction on the track surface behind the spray gate.

"Wang Hu".

"exist."

"Tap the powder again. Sprinkle a handful on each of the three branch lines."

Wang Hu carried the lime bag and ran along the track. He first sprinkled it towards the entrance of the 013 distribution line. The lime dust landed and was swept away laterally by the gap at the bottom of the guide wheel. He then sprinkled it towards the 005 drain trough. The lime dust was similarly sucked in. He then sprinkled it towards the refining furnace cleaning track. The lime dust disappeared even faster there.

Wang Hu tapped the track surface. Clang. Clang. Clang. All three echoes were identical. The area below was empty, connected to the same passageway.

"All three lines lead to the same thing." Wang Hu stepped back. "No matter which line you take, you can't come back."

Su Yuan moved his hand to the control panel.

"012 Press the main rail. The guide pin cannot be pulled out."

The guide pin of the 012 heavy armor forward trolley is already engaged in the old lock hole on the rail surface. The protective shell presses down on the front rail, and the batter head blocks the main line directly in front of the sprinkler door. The guide wheel cannot move it.

"009 card left guide groove".

Wang Hu lowered the old push hook at the front of the 009 road sign commemorative hanger. The width of the 009 wrecked vehicle was just enough to block the end of the stroke of the left guide wheel assembly. The guide wheel could not push the fractured cast iron surface of the 009, and it spun twice before stopping.

"005 silencer sinks half a foot."

The young survivor pushed the control lever. Five tons of counterweight pressed down on the tail of 005, and the thrust of the right guide wheel was sucked into the ground.

"Fully loaded rail clamping module".

All the track pins of the segmented braking array spring into the old locking holes. The heavy-duty brake claws grip the rail surface. The entire train is anchored to the main beam at station number 32.

All three rows of guide wheels spun freely. The red countdown above the sprinkler gate jumped to forty-five seconds.

"Low fire. 20 ring-shaped aiming round. Half-beat phase reversal. Firing into the spray pre-pressure valve."

"receive."

The calibration cartridge is connected to an external horn. Half-second frequency, inverted output. Low-frequency vibrations diffuse from the roof of the Devourer vehicle, traveling along the stainless steel door frame and into the diaphragm mechanism of the pre-pressure valve.

The sprinkler heads are out of sync. The first row of eight sprinklers, which should have been pre-pressurized simultaneously, are now being pre-pressurized in pairs. There's a water hammer sound in the pipes, and the pressure gauge needle is swinging back and forth between the yellow and red zones.

The first row of nozzles sprayed out a few drops of liquid. The sparse droplets landed on the top surface of the 012 protective casing, making a slight hissing sound. The 012 casing was made of military-grade alloy steel, 42 millimeters thick. A few drops of purifier left damp marks on it, but there was no penetration or reaction.

Two-second window of inactivity.

"Wang Hu. Crane boom. Main water pipe."

Wang Hu was already in the crane boom control position. The crane boom was fully extended, and the grab claws gripped the main water pipe at the top of the sprinkler gate from the side. The pipe was about fifteen centimeters in diameter, made of stainless steel, and had condensation on its walls.

The hydraulic pump pressurizes. The gripper tightens. A section of the main water pipe is clamped flat.

Wang Hu pulled the red-hot broken shaft from his tool belt and heated it along the flattened section. *Sizzle.* Steam rose from the pipe wall. The valve sleeve, made of engineering plastic, had cracked under the heat, developing three fissures.

The pressure in the main sprinkler pipe dropped from the red zone to the yellow zone. The pre-pressure indicator lights on the second and third rows of sprinklers went out simultaneously.

Control room at Base 04. The veteran engineer leaned forward, his nose almost touching the screen. He stared at the pressure curve as it dropped.

"He's back-pulling the pipes," the veteran engineer said, turning to the technician. "He's not avoiding the sprinklers. He's depressurizing the sprinkler system."

In carriage 013, the wounded soldier with a chest strap pulled up tilted his head to look at the screen from his stretcher. The screen displayed real-time sprinkler pressure data for station 32. Yellow zone. Moving down.

The showerhead didn't land on the carriage. The fingers gripping the edge of the bed loosened.

Someone spoke in the Bonebreaker channel. The voice wasn't loud, but the channel was quiet, and everyone could hear it clearly.

"It's not afraid of us being dirty. It's afraid of us constantly regrouping."

No one objected. When the red countdown reached thirty seconds, station number 32 discovered the problem.

The sprinkler pre-pressure valve lost pressure. The main water pipe was crushed. The valve sleeve cracked. All the guide wheels on the three branch lines spun freely. The marshalling yard remained stationary.

The broadcast paused for two seconds. Then we changed our strategy.

"Sprinkler system malfunction. Activate backup system."

"High-pressure fog curtain coverage at the top."

"Blood exposure determination procedure initiated."

Above the ceiling, a row of fine-aperture atomizing nozzles descends from a guide rail. These aren't the large-diameter nozzles of a sprinkler door; they're industrial-grade atomizers. What they spray isn't droplets, but aerosols. This atomized air purifier can penetrate any ventilation gap, nail crevices, or hanging joint gap.

Carriage 013 has four ventilation seams on its roof. The newly welded heavy-duty deck is not completely sealed off, leaving gaps for heat dissipation. The atomized air purifier seeps down through these gaps.

Tang Lan looked up. Moisture was condensing at the edges of the ventilation seam.

Su Yuan did not hesitate.

"Mobile refining furnace. External suction inlets fully open."

The external suction port of the refining furnace pops out from the side of the furnace body. The four large-diameter suction ports are activated simultaneously, and the negative pressure zone covers the entire column of trains.

The fog curtain was pulled off course by the suction inlet. The aerosols gathered towards the refining furnace and no longer seeped into the 013 ventilation gap.

"Wang Hu. The main spray pipe, purification tank, filter pump, and drain tank main pipe should all be hung upside down into the receiving rail. Only the nozzle shells should remain."

Wang Hu switched the crane arm to gripping mode. The gripper moved upstream from the flattened position of the main water pipe and grabbed the fixing clamp of the first set of purification tanks. With a twist, the clamp broke. The purification tank was pulled out of the spray door frame and rolled into the storage bin along the receiving rail.

The second one. The third one. All three purification tanks were pulled out. Each had a capacity of about 200 liters, and the tanks were labeled with the concentrations of silver ion complexes and ferromagnetic tracking particles.

The filter pump was located in the cavity of the column on the right side of the spray gate. Wang Hu used a broken shaft to pry open the column panel and pulled out the filter pump along with its base. The pump body was not large, but it contained a three-stage filter element and a magnetic separation rotor.

The main drain pipe is located below the inlet of the 005 branch line. Wang Hu lifted the cover, hooked the middle section of the main pipe with the eight-cable auxiliary cable, and lifted it with the hoisting arm. The entire main pipe was pulled out of the trench, along with a section of elbow and two check valves.

Only the empty nozzle shells remained on the sprinkler door. There were no pipes, no pump, no tank. The empty nozzles were still hissing, releasing residual pressure from the pipes.

Thirty-two seconds. Station number 32 didn't spray anything.

The refining furnace is started at full power. The dark gold conduit is inserted.

Spray pump assembly casing – high carbon steel, recycled. Three-stage filter element in the filter chamber – ceramic and boronized materials, kept as spare parts. Main pipe of the draining tank – standard diameter, kept as a pipeline spare part. Purification tank body – stainless steel, recycled. Purification tank contents – silver ion complexes and ferromagnetic tracer particles, separated and sealed separately.

The refining furnace side chute has started discharging parts.

The first item: a pollution-proof external circulation purification tank. The tank is recast with a stainless steel shell, lined with a boronized filter element and a magnetic separation rotor. It is connected to the air intake on the roof of the Devourer vehicle to filter out trace particles and conductive aerosols from the outside air. In the event of subsequent attacks such as fog, sprays, or aerosols, the external circulation system will filter first.

The second item: a blood isolation curtain for the wounded. The curtain was cut from transparent engineering plastic sections from the main drain pipe, with magnetic strips embedded along the edges. It was hung inside carriage 013 to separate the wounded area from the ventilation seams. The curtain was non-conductive, preventing the purifying agent from reaching the bloodstains and wristbands behind it.

The third item. A sealant nozzle for the 005 armor compartment gaps. A sealant nozzle is created by modifying the magnetic separation rotor of a filter pump and attaching it to the outside of the 005 sealed armor compartment. When conductive liquid seeps into the gaps, the nozzle automatically sprays insulating sealant to seal the gaps.

Fourth item. Dust flushing ring for the energy conduction tube. The original silver ion pipeline of the purification tank is modified into a flushing ring, which is fitted onto the outside of the core energy conduction tube of Zhenshan. The ring has twelve micro nozzles, which use a neutral purifying agent separated from the purification tank to flush away the residual dust on the surface of the energy conduction tube.

Wang Hu received the part. The maintenance team got to work.

Pollution-prevention external circulation purification tank – on the roof of the Devourer vehicle. Four bolts are screwed into pre-drilled holes. The air inlet connects to the external circulation system, and the air outlet connects to the vehicle's internal ventilation. Opening the valve allows airflow through the filter; the main screen displays that the external aerosol concentration has decreased from 12% to 0.3%.

Blood isolation curtain – inside carriage 013. Magnetic strips are attached to both sides of the carriage's interior wall. The curtain hangs down, completely concealing all six stretchers behind it. Mist seeping in through the ventilation gaps is blocked by the curtain, flowing down its surface and into the floor drain.

005 Capsule Sealing Nozzle – 005 seals the outer nail seam of the cap. The nozzle is inserted into the pre-casting slot, with the glue can hanging beside it. The young survivor pressed the test valve, and the glue was squeezed out of the nozzle, filling the nail seam, and curing in thirty seconds.

Black Dust Washing Ring for Energy Conductor – Outside the core energy conductor of Zhenshan. The ring is fitted, with twelve nozzles aligned with the surface of the energy conductor. The valve is opened. Neutral purifying agent is sprayed from the nozzles and flows down the surface of the energy conductor. A layer of dark silver-colored black dust residue is washed away, and the flushed waste liquid flows along the recovery pipeline into the refining furnace waste liquid tank.

Su Yuan watched as all the data on the main screen turned green again.

"Backflush spray door".

The air outlet of the pollution-prevention external circulation purification tank is switched to reverse mode. The purified airflow is pushed down from the roof, directly towards spray door number 32.

The remaining fog is pushed back inside the spray gate by air pressure. The fog is then drawn back into the empty spray pipes and into the recovery tank. There is water at the bottom of the recovery tank, and the fog condenses upon contact with the water, causing the liquid level to rise.

The empty nozzles of the three spray doors simultaneously bear the internal air pressure. There is no pipeline depressurization. There is no pump to divert the pressure. The air pressure is trapped inside the empty shell and pushes upwards.

*Crack.* The first nozzle in the first group exploded. Stainless steel fragments were ejected and slammed into the empty outer armor frame.

*Snap. Snap.* Second group. Third group.

All three sets of twenty-four nozzles exploded within four seconds. Stainless steel fragments and remnants of pipes were scattered all over the ground. White mist billowed from the rupture, but without direction or pressure, spreading along the ground and quickly dissipating.

Disinfection line #32. The spray door is empty. The pipeline is empty. The pump is empty. The tank is empty. The spray nozzle is broken. The public address system is down.

The entire channel was silent for three seconds.

Then the communications officer from the Bonebreaker spoke first. "Disinfection Line 32. Rules in effect."

The slaughterhouse fire control officer then confirmed, "The sprinkler system has been removed."

Control room of Base 04. Lu Mingyuan stood, his fingers pressing on the table.

"The rules at Station 32 are invalid. Spraying, disinfection, and single-cabin epidemic prevention are all now considered diversion traps." He paused. "The train operation principles have been updated. Any requests for diversion or separate passage at any station under the guise of medical treatment, epidemic prevention, or purification will be considered a train formation revocation trap."

Bonebreaker. Slaughterhouse. Base 04. Simultaneous confirmation across three channels. All marker colors changed to dark gray.

Fill in square 32 after the string of gray squares from 19 to 31. This applies to thirteen consecutive stations.

Tang Lan removed her hand from the gun handle. She walked inside carriage 013 and pressed the magnetic strip on the blood isolation curtain again. The curtain completely blocked the ventilation gaps. Behind the curtain, the breathing rates of several wounded soldiers had slowed down.

The hemostatic injection worked. The medicine is genuine.

Tang Lan took out frostbite repair gel from the medicine cabinet and applied it to the blackened areas of the injured person's toes, whose leg was in a splint. As the gel was applied, the edges of the blackened skin turned red, and blood began to flow back.

She didn't speak. Neither did the wounded.

Direction 005. A young survivor crouches outside the hull, his palm pressed against the newly installed sealant nozzle. The sealant pressure is normal.

"Tail boom 15.6. Cabin sealing complete. Seals untouched."

The flushing ring outside the core energy-conducting tube of Zhenshan stopped. Waste liquid flowed into the refining furnace along the recovery pipeline. After the layer of dark silver dust on the surface of the energy-conducting tube was washed away, the dark gold metal body was revealed. It was clean.

Su Yuan withdrew his hand from the control panel. The refining furnace temperature returned to the standby range.

他看了一眼009残车。三毫米弹簧沉默着。断裂支架朝上。009从19号站开始标路，一站一站，钢片、道钉、报码。32号站的钢片是从假013药柜里弹出来的。009把路标藏进了假车的真药柜里。

Trusted road sign source.

"012 continues to press the front rail. The entire train moves forward."

The 012 heavy armor forward-propelled pulley pulled out its rail pin and slid forward. The 009 mounting bracket swayed slightly. The Devourer followed. Section 3. Number 013. Number 005.

The train departed from disinfection line number 32. Behind it were shattered spray doors and a pile of stainless steel fragments.

There are no station signs ahead. Direction 33.

The radar on the small fire swept across two hundred meters ahead. The data appeared on the main screen.

"Water Recycling Station No. 33"

A wave of blue light suddenly appeared ahead. Not white, not red. It was blue light. It shone from the light strips on both sides of the track, illuminating the track surface with a bluish glow.

The radio came on. An old cassette tape.

"Water Recycling Station No. 33. The entire train can be directly replenished with water."

No uninstallation required. No traffic splitting required. No countdown timer. No guide wheels. No rail clamps.

The broadcast only repeated one sentence.

"The entire formation can be replenished with water directly."

Su Yuan stared at the blue light. He neither slowed down nor sped up. The car maintained a speed of one and a half kilometers per hour.

Wang Hu leaned out from the outer beam to look ahead. The blue light shone on his face, making the scars appear bluish.

"You're too kind this time."

Xiao Huo retrieved the data from the waste liquid tank of the purification tank. The waste liquid was recycled after rinsing the energy conduction pipe at station No. 32, and it contained residual black dust and a mixture of purification agents.

There is a layer of sediment at the bottom of the waste liquid tank. A small flame was used to obtain the spectral analysis results of the sediment.

The data jumped three times.

Then Xiao Huo reported a string of codes.

"A reverse code was detected in the waste liquid sediment."

Su Yuan's hand stopped on the control panel.

"content."

The little torch-shaped code translator was pushed to the center of the main screen. A line of text appeared.

The reflection of the previous 001 is in the water.

The 012 heavy armor advance sled has entered the range of the 33rd blue light. The blue light shines on the 012's new hull, reflecting a cool, arcing light. The track ahead is clean, with no dust reaction, no suction, and no cavities.

However, when the 012's wheel flange crossed the rail surface, blue light shone through the rail gaps and onto the underside of the 012 chassis. The shadow cast under the chassis was incorrect.

012 has only four wheelsets. There are five in the shadow.

The wheels of the entire train rolled over the blue light track gaps, and tiny, cold lights darted out from the gaps in the chassis. The extra fifth wheel shadow was firmly stuck to the track projection, not moving with the train body, not shifting with the light, and was nailed to the azure track light, eerily chilling.

Wang Hu's smile vanished instantly, and he immediately shrank back from the outer beam, his fingertips already gripping the track detector at his waist. Wasteland stations never offer benevolent gifts; the trap at Station 32 had just been broken, and this seemingly effortless "hydration benefit" at Station 33 was, from beginning to end, a chillingly deceptive facade.

The small fire's radar continuously scanned the airspace and orbital structure ahead at overclocked frequency, the main screen data stream scrolled and refreshed wildly, and the entire area covered by blue light was showing a magnetic field frequency shifting at a constant speed. The seemingly stable clean water area was actually silently reshaping the magnetic field trajectory of the entire train formation.

"The extra wheel shadow is not an optical error, but an overlap of the underlying track load projection." Xiao Huo's cold mechanical voice broke the silence of the carriage. "Matching data: Lost front-wheel drive train, chassis characteristics of probe car No. 001."
