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

The Devourer drove out of the ruins of Station 34. The newly installed rail-front material scanning radar rotated silently on the roof of the vehicle, and the fan-shaped scanning area moved forward, peeling away the layers of the track ahead.

The 012 heavy armored forward trolley rested on the main rail, its newly cast protective shell still bearing scratches from the stainless steel fragments splashed on at the previous station. Wang Hu squatted on the outer beam, his flashlight sweeping across the 012's wheel rim. The rim was dry, without any watermarks. The indicator light for the independent clean water circulation chamber glowed green under the vehicle, all water circuit shut-off valves were closed, and the key was tucked into Su Yuan's inner pocket.

On the commemorative hanger for the 009 road sign, a three-millimeter spring lies silent. The broken bracket faces upwards, the old cast iron fracture glowing a dark red in the halo of the car headlights.

"Station 35." The little torch pushed the radar data to the main screen.

Two hundred meters ahead, the light strips on both sides of the track shone a cool white. Not blue, not red. The clean white light made the track surface look as if it had just been wiped clean. At the platform entrance stood an iron sign, white background with black lettering in the old Blue Star standard printed font.

"Vehicles with abnormal water samples should change the water before proceeding."

There was no countdown timer. There were no guide wheels. There were no directional signs.

Wang Hu pinched a pinch of powder and sprinkled it onto the rails. The white powder landed on the dry rails, remaining naturally scattered. He tapped the rails; the echo was dull, without any hollow sound.

"The surface is clean." Wang Hu stood up and brushed the dust off his hands.

Su Yuan stared at the upper right corner of the main screen. The fan-shaped scanning area of ​​the pre-track material scanning radar had already crossed the iron sign and penetrated deep into the platform. The radar echo refreshed layer by layer, revealing the true structure of Station 35.

The water replacement rail is located directly in front of the main rail, with its surface half an inch lower. Six sets of vent valve interfaces are arranged on both sides. Below the water replacement rail, thermal imaging shows a row of dark red preheating equipment outlines. Disassembly rollers: Three sets, with spacing matching the wheelbase of mounting points 013, 005, and the refining furnace.

To the right, a partially open materials warehouse. The door was only a third open, with blue-green indicator lights shining through the crack. Radar penetrated the wall, revealing rows of cooling boxes, high-speed pump sets, and standard water tanks. Unopened. Neatly stacked.

"Just like No. 34," Wang Hu said, "there are real materials piled up behind the trap track."

Su Yuan didn't reply. He looked to his left. A green arrow on the left track pointed to a clean branch line. At the entrance to the branch line was a small metal sign: "014 Backup Cooling Cart has just passed; you can follow the train to collect it."

Xiao Huo pulled up the thermal image of the branch line. There was indeed a low-temperature wheel mark on the track, with the wheel track width consistent with the standard carriage. However, the brightness of the low-temperature wheel mark had diminished, and the edges were blurred, indicating it wasn't recently left.

"The low-temperature residue lasted for approximately seventeen minutes," Xiao Huo reported. "This does not match the standard speed of vehicle 014. It was towed there."

In the control room of Base 04, the technician retrieved the backend logs left by Unit 34. The log entries were clean, the signatures for the water quality anomaly records were complete, and they used the standard format of the old Blue Star Expeditionary Force. Sampling time, sampling location, and analysis of abnormal components were all filled in neatly.

"Before analysis tower #34 burned down, the anomaly label had already been written into the access log for tower #35." The technician tapped on the screen. "The process was complete."

The veteran engineer stood behind him, staring at the signature format on the screen. "Standard procedure on Old Earth. Not faked, genuine system access."

No one answered the phone in the control room.

The announcement came on. The voice at station 35 was drier and the pauses were more awkward than at the previous stations, but the pace was steady.

"Water quality monitoring station No. 34 uploaded an abnormal water sample record. Record number ZD-034-0917. Abnormal components: silver ion complex residue, ferromagnetic trace particles, high-temperature metal ions, and unknown organic matter."

The broadcast paused for a second.

"Vehicles with abnormal water samples, please proceed to the water exchange track. The entire trainset shall remain in place. Proceed only after the abnormal water source has been emptied."

"005 tail anchor car enters temporary storage tank. Mobile refining furnace disconnects external circulation."

"You can pick up the 014 spare cooling compartment by following the tracking line on the left."

Three sentences, each outlining the green health code process. No threats, no countdown. Just standard procedure.

Inside the No. 013 casualty compartment, the temperature gauge on the cooling cabinet, which had just stabilized, began to fluctuate. The needle drifted from the green zone towards the yellow zone, and the cabinet emitted a slight hum. The sound of water flowing suddenly became rapid in the newly connected high-pressure water supply pipe.

Tang Lan turned and walked to the cooling cabinet, pressing her palm against the cabinet body. The cabinet body vibrated, the vibration frequency matching the pre-pressurization frequency of the vent valve at station number 35.

"It's under pressure in the pumping circuit," Tang Lan said.

A wounded soldier with a splint on his leg stared at the water pipe in the medicine cabinet. The water in the pipe began to flow backward, the clear water being pumped back, and the surface of the water dripped down in sections. Another wounded soldier with a brace around his chest flipped his wristband over and fastened it, his fingers pressing down on the edge of the wristband.

"This time there's no spraying," the person who had previously suggested transferring the seriously wounded said in a low voice. "This time it's direct suction. Legal suction."

In the control room of Base 04, the technician turned the pipeline diagram of Station 35 to full screen. The interface specifications of the vent valve and the newly installed independent clean water circulation chamber, high-pressure water supply auxiliary pipe, 005 external water storage tank, and Zhenshan energy conduction pipe waste liquid recovery box of the Shihuang were completely consistent. It was not a temporary match, but a standard configuration.

"Its drain valve has a standard interface." The technician's expression changed. "It can be directly connected to our water system. It's not a forced pumping, it's a compliant drain. The system will recognize this as a normal water change procedure."

In the Bonebreaker channel, the communications officer's voice was muffled. "Tag on the 34th, legal demolition on the 35th. Two stations working together, green code process, proper signature. How the hell do we break this?"

The fire control officer at the slaughterhouse didn't respond. A few seconds of silence followed before someone spoke in a low voice.

"This time it's like real permissions."

The veteran engineer stared at the piping diagram, his finger pointing to the interface specifications of the vent valve. "It's not afraid we won't connect. It uses a standard venting protocol; not connecting is a violation. A convoy violating this rule entering the main road of the Great Wall will have consequences far more severe than having its vehicles dismantled."

On both sides of the water exchange rail at Station 35, six sets of drain valves simultaneously popped out. The valve bodies are standard type, with cast iron outer shells, ceramic valve cores, and interfaces equipped with automatic locking claws. The locking claws are aligned with the outlet of the independent clean water circulation chamber under the Shihuang vehicle.

The door to the right-hand materials warehouse opened a crack a little wider. Through the crack, rows of blue and green indicator lights on the cooling tanks were lit. The nameplate on the high-speed pump unit reflected the light, the lettering clear. An old label was affixed to the outer shell of the double-layered water tank: "Station 35 Materials Inventory - Unopened".

The green arrow on the left tracking line flashed, and an old Blue Star dispatch code appeared above the cryogenic wheel mark of 014: "014 Backup Cooling Carriage, legally available for pickup."

Bait. Materials. Legal procedures.

Pressure is being applied from all three fronts simultaneously.

Su Yuan's hand rested on the brake valve.

"I'm not going to chase 014," he said.

Wang Hu stood up from the outer beam, picked up a bag of lime, and sprinkled some lime powder into the gap between the water-changing rails. The white powder fell, but before it even touched the rail surface, it was drawn into the gap by the rising airflow generated by the preheating of the dismantling rollers. The powder tumbled and swirled within the gap, its trajectory chaotic, before finally being sucked under the rails.

"Replacing the water rails means dismantling the train rails." Wang Hu stepped back.

"Don't change the water," Su Yuan said.

He switched to the control interface of the water pollution investigation module. The investigation module, recast from the fluorescent salt silo and magnetic powder recovery disc seized at Station 34, was connected to the bypass of the independent water purification circulation chamber. The module started, and the water sample in the inlet pipe was drawn into the analysis chamber.

The spectral data jumps onto the main screen layer by layer.

Silver ion complex – Source: Residue from the purification tank at Station 32. Ferromagnetic tracer particles – Source: Adhesion from the collection arm spray at Station 34. High-temperature metal ions – Source: Trace amounts of flue gas condensed during the refining furnace's water storage tower.

All three components were contaminated from the outside. The water inside the Devourer's own water tanks, pipes, and storage containers was clean.

"The abnormal water sample did not come from the Devourer's water tank." Little Torch pushed the analysis data to the center of the main screen. "The abnormal components are all external environmental residues. The analysis tower at Station 34 integrated the spray residue from the collection arm, the condensate from the refining furnace flue gas, and the residue from the purification tank at Station 32 into a single 'abnormal water sample' record."

In the control room of Base 04, the technician suddenly stood up. His chair slid back half a meter, bumping into the control panel behind him. He pointed at the reverse data displayed on the screen.

"Fake labels. All the labels used by number 34 are fake. They didn't collect any water samples from our tank; they reported environmental residues as an anomaly in the water source."

The veteran engineer leaned forward, his nose almost touching the screen. "It sprayed the fluorescent salts itself, collected them itself, analyzed them itself, and labeled them itself. Then Number 35 took those labels and legally dismantled our waterways."

In the Bonebreaker channel, the communications officer cursed, "Insidious."

On both sides of the water exchange rail at Station 35, six sets of vent valves began pre-pressurization. The valve cores rotated, and the locking claws opened. At the same time, at the bottom of the temporary storage tank next to 005, the pusher slowly rose. The rubber pad at the front end of the pusher was aligned with the side of the enclosed compartment of 005.

The broadcast started again.

"Vehicle with abnormal water sample, please proceed to the water exchange track. Remaining privileges: 20 seconds."

"005 Tail anchor carriage enters temporary storage tank."

"Refusal to change the water will be subject to mandatory drainage."

Su Yuan withdrew his hand from the control panel.

"Wang Hu. 009 steel sheet. Replace the side seam of the water rail."

Wang Hu pulled the thin steel sheet left by 009 from the outer beam storage tank and attached it to the front of the observation slot on the side seam of the water change rail. The vibration generated by the pre-pressurization of the vent valve was transmitted into the steel sheet, and the old engravings were shaken to a slight shine. A line of hidden text emerged.

"The water isn't dirty, but the valve will malfunction and damage the car."

Wang Hu flipped the steel plate over to confirm there were no other markings. "009 said the water wasn't dirty. The valve is the one that bites."

Su Yuan's fingers tapped rapidly on the control panel.

"The network disconnection valve is fully closed."

The outlet valve of the independent water purification circulation chamber, the inlet valve of the high-pressure water supply auxiliary pipe, the gravity flow valve of the 005 external water storage tank, and the drain valve of the Zhenshan energy conduction pipe waste liquid recovery box were all closed. The mechanical locks were locked, and only Su Yuan had the key.

"013 Cooling cabinet external valve shut off."

Tang Lan had already taken action. She tightened the handwheel of the external valve of the cooling cabinet, turning it round and round until it was fully closed. The valve core was locked shut, cutting off the water supply. The humming of the cooling cabinet immediately stopped. The vibration of the cabinet disappeared, and the temperature gauge needle stopped at the edge of the yellow zone, no longer fluctuating.

The backflow in the pipes has stopped. The level of purified water has stabilized and is no longer dripping.

"Second tightening of the locking pin on the 005 water storage tank cover".

The young survivor crouched beside the 005 enclosed compartment, tightening the locking pins of the cut-resistant shield with a wrench. The pins engaged in the positioning grooves of the shield's base, minimizing the gap between the shield and the tank. The rubber pad of the pusher was still half a meter away from the shield, unable to be pushed.

"012 Pressure replacement of water rails".

The 012 heavy armor's forward-probing pulley pulled out the rail fixing pin and slid forward. The front end of the protective shell pressed into the water change rail inlet, with the newly cast military-grade alloy steel pressing against the rail surface. The dismantling roller below the water change rail spun twice without engaging the bottom of the protective shell. The 012's chassis was not a standard carriage structure; the wheelbase and dismantling roller were mismatched.

"009 card left tracking line."

Wang Hu lowered the old push hook at the front of the commemorative 009 road sign hanger. The broken cast iron surface of the 009 wrecked train got stuck in the gap of the switch on the left tracking line. The switch's switch mechanism was stuck by the cast iron and could not cut to the left. The green arrow flashed twice and then went out.

"005 Sinking Mute Drop".

The young survivor pushed down the control lever. Five tons of counterweight pressed down on the rear of 005, and the entire car sank into the ground. The pusher of the temporary storage tank hit the side wall of 005, but the thrust was blocked by the silencer and counterweight. 005 remained motionless.

Station 35 detected that all marshalling yards were locked, and the speed of the dismantling rollers for changing water rails began to increase. However, at the same time, the pre-pressure of the vent valve began to build up due to the closure of the network disconnect valve. The valve core emitted a harsh metallic friction sound under high pressure.

The broadcast came on for the third time, this time with the speech a beat faster.

"The vent valve is overloaded. The system will activate the main valve array to force venting."

The trench covers on both sides of the water rail popped open. Inside the trench, a whole row of main valve arrays rose up. The high-pressure pump set, the main exhaust valve, the cooling tower base, and the right warehouse door lock beam were all standard equipment, and each piece of equipment had a nameplate from the old Blue Star Expeditionary Force on its base.

The main valve array's piping is three times thicker than the vent valve, and the interface specifications are also standard. The locking claws open and align with the independent clean water circulation chamber, high-pressure water replenishment auxiliary pipe, external water storage tank, and waste liquid recovery box on the underside of the Devourer vehicle.

"Eight cables. Connected to the main pump house."

Eight steel cables were thrown from the roof of the "Desertification" vehicle. The cables slid along the edge of the trench, and the hooks caught on the anchor bolts of the main pump house base. The anchor bolts were old-style flange structures, and the bolts were severely corroded.

"Anti-drag".

The refining furnace output power was increased. All eight cables were tightened simultaneously. The anchor bolts of the main pump house base deformed under the tension of the rusted bolts. One bolt after another broke. The entire main pump house was pulled out of the trench by steel cables, with the pump body connected to a section of the inlet and outlet pipes, suspended in mid-air.

Wang Hu operated the crane arm, gripping the inspection ring in the middle of the pump house and controlling its tilt. The main pump house was pulled horizontally above the material receiving rail.

"Refining furnace. Dark gold conduit. Main valve array."

The side of the refining furnace cracked open. Four dark gold conduits protruded, sliding along the edge of the trench. The first one pierced the power supply busbar of the high-pressure pump unit, burning it out. The second one pierced the control line of the main vent valve, the valve core being welded shut by the high temperature. The third one pierced the return water pipe of the cooling tower base, the return water pipe breaking. The fourth one pierced the hydraulic push rod of the right silo door lock beam, the push rod melting away.

The high-pressure pump unit's operating sound changed from a high-pitched tone to a hoarse whine, and finally stopped. The main vent valve's valve core was stuck in the open position, but the pipeline was broken, resulting in no pressure. The liquid level at the cooling tower base dropped rapidly after the return water pipe broke, and the tower body emitted a hollow echo. After the hydraulic push rod of the right silo door lock beam melted, the silo door lost its support.

"Lifting boom. Smash the waterway lock boom."

Wang Hu switched the crane arm to gripping mode. The gripping claw swept out, smashing into the six sets of drain valve interfaces on both sides of the water change rail. The cast iron valve bodies cracked under the heavy impact, the locking claws broke, and valve core fragments flew out and smashed against the inner wall of the platform.

All the vent valves have failed.

"Take it all."

The refining furnace is started at full power. The main pump chamber feeds into the furnace, the pump casing is flattened, and the steel is melted. The main vent valve body is disassembled, and the ceramic valve core is removed for spare parts. The plunger and cylinder of the high-pressure pump unit are separated; the plunger is kept as a hydraulic spare, and the cylinder is returned to the furnace. The stainless steel plate of the cooling tower base is cut off and sent into the side slot. The lock beam and hydraulic push rod of the right hopper door are completely disassembled, and the metal parts are sent into the furnace.

The dark gold conduit continued to extend, embedding itself deep into the pipeline system in the trench. The remains of the water tank were dragged out, flattened, and sent into the furnace. The drive motor for the dismantling rollers was located; the power supply to the conduit was cut off, and the motor stopped. The roller shaft and bearings were removed, and the metal parts were returned to the furnace.

The side slot begins to eject parts.

The first component is the heavy-duty cooling circulation cabinet. It was recast using the main pump house shell and cooling tower base, and the cabinet itself has three layers. The upper layer is the heat exchange core, the middle layer is the high-speed cooling pump, and the lower layer is the buffer water tank. The cabinet is connected next to the independent clean water circulation compartment under the Devourer vehicle. Once connected, the coolant begins to circulate.

The second component is a dual-tank redundancy module. It was recast using the remains of the water storage tank below the water rail and the stainless steel valve of the main drain valve. The two tanks are connected in parallel with an isolation valve in between, allowing switching to the other tank if one is damaged. It is connected between the cooling circulation cabinet and the high-pressure water supply auxiliary pipe.

The third component is the rapid cooling jacket for the energy conduction tube. It is recast using the ceramic valve core of the vent valve and the return water pipe of the cooling tower. The jacket is divided into six sections, each with an independent coolant channel. It is fitted onto the outside of the core energy conduction tube and locked in place. When connected, coolant flows through the inside of the jacket, and the surface temperature of the energy conduction tube drops from the yellow zone back to the green zone.

The fourth component is the antifreeze layer for the 005 water tank. It's a recast version of the hydraulic push rod housing from the right door lock beam and the disassembly roller bearing. It has a double-layer structure with insulation cotton sandwiched in between. It's attached to the outside of the 005 external water tank, replacing the original cut-resistant cover. It provides integrated antifreeze and cut-resistant protection.

The fifth component is the temperature-stabilizing auxiliary circuit for the 013 medicine cabinet. It is recast using the plunger from the high-pressure pump set and the main pump room outlet pipe. It is connected next to the cooling cabinet in car 013, in parallel with the high-pressure water supply auxiliary pipe. The temperature-stabilizing auxiliary circuit has an independent temperature control valve, unaffected by external pipeline pressure fluctuations.

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

The heavy-duty cooling circulation cabinet was welded into the vehicle's underside, the inlet and outlet water pipes were connected, and a fluid flow test was conducted. Coolant circulated within the cabinet, the heat exchange core functioned normally, and the buffer tank level remained stable. On the main screen, the cooling system data jumped from the yellow zone back to the green zone.

The dual-tank redundant module was attached to the outer beam of the "Devouring Wasteland" vessel. The isolation valve opened, connecting the two tanks. The level gauge indicated a full tank.

The core energy conduction tube is fitted onto the rapid cooling jacket. All six clips of the jacket are tightened. With the coolant connected, the internal temperature of the jacket drops rapidly, and the surface temperature of the energy conduction tube stabilizes at the center of the green zone.

The antifreeze layer on water tank 005 is secured. The young survivor tightens the locking pin, pressing his palm against the outside of the antifreeze layer. The tank temperature stabilizes.

The temperature stabilization circuit of medicine cabinet 013 was connected. Tang Lan opened the temperature control valve, and coolant flowed into the temperature stabilization circuit. The temperature of the medicine cabinet was pulled back from the edge of the yellow zone to the center of the green zone. The hemostatic agents, anti-infective injections, nerve pain relief patches, and frostbite repair gel inside the cabinet all returned to their optimal storage temperatures.

All green health codes at station number 35 were simultaneously deactivated.

Fragments of the vent valve were scattered all over the floor. The main pump room was empty. The main vent valve was stuck in the open position but no pipes were connected. The cooling tower base was just an empty shell. The drive motor for the dismantling rollers had stopped, and the roller shafts had been removed.

The water track was replaced, but it became a dead track.

The door to the material warehouse on the right lost its locking beam support and tilted inward. Wang Hu grabbed the edge of the door panel with the crane arm and pulled. The entire door was ripped off, revealing the interior of the material warehouse.

Rows of cooling tanks glowed with blue and green indicator lights. The high-flow-rate cooling pumps were brand new, their nameplates displaying standard flow parameters. The double-layered water tanks remained unopened, their outer labels intact. Cold-resistant tubing was wrapped in protective film, its diameter compatible with the existing piping on the Devourer. Long-haul heat exchange fins were neatly stacked on shelves, each individually packaged. Standard heat exchange cores were stacked in wooden crates, the lids spray-painted with the old Blue Star Expeditionary Force's supply codes.

Deep inside, a complete set of interface adapter racks is fixed to the wall. A handwritten label is affixed to the rack: "014 Cooling Interface Adapter Rack - No. 35 Spare Part".

"Eight cables. Wall-mounted."

Wang Hu hung eight steel cables on the load-bearing wall inside the material warehouse. The refining furnace's output power was increased. The entire wall was pulled open, completely exposing the material warehouse.

"Take it all."

The crane arm extends into the material warehouse, grabbing entire rows of items. Cooling boxes, pump sets, water tanks, cooling pipes, heat dissipation fins, and heat exchange cores all roll into the storage area along the receiving rails. The 014 interface adapter rack, along with its wall-mounted bolts, is unscrewed and placed separately into the material hanging bracket.

The refining furnace was restarted.

The high-flow cooling pump was disassembled, the impeller and pump body were separated, the pump body was recycled, and the impeller was kept as an upgrade spare part for the high-speed cooling pump. The double-layer water tank was not unsealed and was directly hung on the reserved mounting position next to the external fuel rack. The original ordinary water pipes in car 013 were replaced with cold-resistant cooling pipes, which have thicker walls and stronger low-temperature resistance. The long-haul heat dissipation fins were welded to the outside of the energy conduction tube fast cooling jacket to increase the heat dissipation area. The standard heat exchange core was installed in the upper layer of the heavy-duty cooling circulation cabinet to replace the temporary heat exchange core. The 014 interface adapter frame was hung on the external mounting frame above the 005 tail anchor, and the interface specifications on the frame were completely consistent with those of the 014 cooling car mentioned in code 009.

The Devourer has completed its heavy-load cooling upgrade.

In the upper right corner of the main screen, the stability of the Zhenshan core parallel connection jumped from 68% to 73%. The temperature of the energy conduction tube stabilized in the center of the green zone. The temperature of the external fuel rack returned to green. The 013 medicine cabinet cooling system is completely independent of the platform water source and operates independently. The temperature on the outside of the antifreeze layer of the 005 water storage tank is 5 degrees Celsius above zero, and the water temperature on the inside is 8 degrees Celsius above zero. The stress of the 005 tail beam stabilized at 14.8, below the red line.

In the control room of Base 04, Lu Mingyuan pressed the full-channel broadcast button.

"Records at Station 34 are invalid. Rules for Station 35 are null and void. Water quality monitoring, labeling, legal diversion, and forced drainage are all subject to the branch dismantling trap."

He paused for a moment, his fingers pressing on the table.

"From the 19th to the 35th, the system broadcasts at seventeen consecutive stations were all false rules. The accuracy rate of Route 009 has been updated to 100%. The driving principles have been updated. Supply stations will only dismantle depots, not take over operations, and will not chase after decoys."

The three channels, namely Bonebreaker, Slaughterhouse, and Base 04, confirmed the information simultaneously.

Fill in block number 35 after the string of gray blocks.

On the Bonebreaker channel, the communications officer's voice laced with laughter. "Seventeen stations. Demolished all the way here. Turned into an arsenal."

The slaughterhouse fire control officer chimed in, "The more we dismantle it, the heavier it gets. So heavy that even the legal procedures of the system can't withstand it."

In the control room of Base 04, the technician turned on the full-screen grouping data for the Devourer. The heavy-duty cooling circulation cabinet, the dual-tank redundant module, the energy pipe rapid cooling jacket, the antifreeze layer of the 005 water storage tank, and the temperature-stabilizing auxiliary circuit of the 013 medicine cabinet—every single item was showing a green light.

"The grouping integrity is 100%. The redundancy of the cooling system has been improved. The parallel stability of the Zhenshan core has reached a new historical high."

The veteran engineer looked at the data on the screen without saying a word. After a while, he tapped the 014 interface adapter frame with his finger.

"The fact that this thing allows station 35 to keep spare parts means that 014 didn't just run away on its own."

The thermal trace data on the adapter bracket was retrieved using a small flame. The residual thermal traces were faint but regularly distributed. The contact surface of the adapter bracket had symmetrical friction marks, indicating that it had been fastened with a standard connector.

「014备用冷却车厢不是自己开走。」小火把分析结果推到主屏，「它被015牵引补给车用标準流程领走。适配架是015牵引补给车领走014时从联挂器上换下来的，留在35号站当备件。」

In the upper left corner of the main screen, the scanning beam of the new radar extends forward. In direction 36, two parallel heat marks appear on the track.

A low-temperature wheel mark, with the same wheel track as the standard car, and clear edges, indicating it was just left. 014 Cooling Car.

The other one is heavier and wider. The wheel rut depth is twice that of 014, and the rail surface indentation is coarser. At the rear of the vehicle, thermal imaging captured a blurry residual image of the spray-printed code.

The afterimage of the small torch's inkjet printing is magnified and enhanced frame by frame.

The afterimage stabilized.

"Supply tractor No. 015. Fully loaded and currently towing."
