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

A red dot in one corner of the black box flashes rhythmically.

Without waiting for instructions, Xiao Huo immediately played the decoded audio outside the main control room.

"Beep...beep beep...beep..."

The Morse code, intermittent and mixed with loud electrical noise, was transmitted intermittently.

Overlapping with it was a heavy, irregular heartbeat. The sound didn't seem to be recorded through a microphone; it was more like each heartbeat directly striking the metal casing—dull, oppressive, carrying a sense of imprisoned, dying struggle.

Inside the 013 wounded personnel compartment.

Jiang Yu's body froze instantly.

He sprang up from the stretcher, ignoring the fact that his newly bandaged arm wound had reopened and blood had soaked through the gauze. He lunged at the communicator like a madman, staring intently at the flashing red dot.

What surged in his eyes was a tidal wave after fourteen years of dead silence.

"...It's him." Jiang Yu's voice trembled violently, each word squeezed out through clenched teeth, "This premature ventricular contraction frequency...it's him! The train conductor!"

Fourteen years.

He firmly believed the entire team had perished, and for fourteen years he wandered alone in the dark underground like a lost soul. But that tiny, almost imperceptible heartbeat was etched into his very bones; he could never forget it.

That was the commander of vehicle 011, Ji Yun's deputy, the man who ordered Ji Yun to lead the team to break through at the last moment.

In the control room, Su Yuan tapped his fingers on the control panel, his face showing no emotion.

"Small fire, underlying logic."

"Warning!" Xiao Huo's electronic voice suddenly escalated, "The underlying signal protocol has detected a fake wake-up command! Living Metal is using the commander's real distress signal as a high-privilege decoy. Once we disable the physical protection layer or attempt two-way communication, it will immediately take over our underlying protocol!"

This is a trap.

A cruel trap set with the sound of a hero's last heartbeat.

Su Yuan did not hesitate at all.

His finger landed directly on the red button on the control panel.

"Burn off the electrodes, but retain the one-way reception."

An invisible, powerful pulse shot back towards the signal source. A soft popping sound came from inside the black box, and the unsettling, abnormal heartbeat abruptly stopped, leaving only a faint, clean Morse code stubbornly transmitting.

The listening to the living metal was forcibly severed.

There are no more tracks ahead.

The only way was the bottomless descending cavern that the aggregate drill bit had created when it crashed into the rock wall as it fled.

Su Yuan gripped the power push lever, his voice as cold as ice.

"All units, advance!"

The Devourer did not reverse.

The forty-eight newly installed heavy-duty rail spikes on the front of the locomotive suddenly changed angle, like the claws of a beast, and firmly gripped the rough rock grooves left by the drill bit. The engine of the core of the mountain-suppressing machine roared deafeningly, and the three-hundred-ton steel behemoth abandoned the rails, rushing directly into that rugged, chaotic, dark abyss at a speed of sixty kilometers per hour!

It gripped the drill bit debris tightly, driving madly downwards.

It descended to a depth of 650 meters.

The entire cave passage ahead began to tremble violently.

The heavily damaged polymer drill bit, using its control over the rock strata, forcefully collapsed a 300-ton layer of carbonized rock above. Boulders and abandoned steel beams rained down like a storm, attempting to bury the Devourer alive on the spot.

Su Yuan did not slow down.

He turned around and pulled the negative pressure lever of the external suction port of the mobile refining furnace all the way to the bottom!

"Dinner's ready!"

The furnace opening, at 1,500 degrees Celsius, transformed into a colossal abyss beast that devoured everything.

The boulders and twisted scrap steel that crashed down were captured by the terrifying suction the moment they came into contact with the negative pressure field, and were all drawn into the furnace chamber and melted on the spot!

The Devourer managed to carve out a path through the devastation of a collapsing city!

On the roof of the car, Wang Hu gripped the guardrail with one hand while frantically waving the other hand across the control panel.

The heavy-duty crane arm directly poured the molten alloy, which had just been quenched by the refining furnace after consuming rocks and scrap steel, into the cooling mold of the railway gun barrel.

A heavy armor-piercing projectile, in a semi-molten state and entirely reddish-brown, was cast on-site!

The hydraulic system of the train gun base roared, and the muzzle was aimed directly at the tail of the drill bit wreckage that was fleeing for its life.

Open fire!

The high-temperature warhead with ultra-high kinetic energy, like a destructive meteor, instantly pierced through the core high-pressure chamber of the drill bit.

"boom--!"

A dull explosion erupted inside the drill bit, spraying out countless pieces of track debris and metal fragments. The monster that had roamed the underground was finally paralyzed at the end of the cave.

The Devourer stopped in front of the drill bit wreckage.

The dark gold conduit of the mobile refining furnace popped out like a venomous snake, precisely piercing the core of the drill bit and forcibly draining all the remaining liquid metal and high-strength alloy skeleton inside.

"Recasting complete: Deep-earth heavy-duty rock-breaking shovel."

"Reforging complete: High-frequency vibration hull armor."

Wang Hu and his team braved the high temperatures to quickly complete the front end replacement. The originally flat front end was now covered by a menacing giant rock-breaking shovel and thick armor filled with vibration cells.

The Devourer filled its last gap in off-road capability, transforming into a true steel earth dragon, and continued to dig deeper underground!

The high-frequency vibrating shovel at the front of the vehicle shattered the last layer of high-density carbonized rock.

"boom!"

The Devourer plunged into an enormous underground cavern.

813 meters underground.

The Pangu Project 058 symbiotic nest.

There are no platforms or tracks here.

Only a colossal, slowly pulsating dark golden neural network suspended above the scalding reaction pool below. The air was filled with neurotoxins powerful enough to instantly cause brain death in ordinary people, and all conventional radars were instantly rendered useless by the strong magnetic field interference.

Switch to backup optical radar with a small flame.

The main screen freezes.

In the center of the cavity, above the reaction pool, hangs a tall tower woven from countless dark gold living metal cables.

At the very center of the densest concentration of cables, a person was suspended in mid-air, pierced through the limbs and spine by hundreds of metal pipes of varying thicknesses, like a human-shaped battery.

His chest rose and fell slightly with his faint heartbeat.

Those persistent Morse code sounds were the sounds he made as he used his last bit of strength to control the remaining pump in his heart, repeatedly striking his ribcage.

Fourteen years.

He used his own body to send out distress signals for fourteen years.

A hoarse, dry, almost distorted voice suddenly cut into the driver's cab through the communicator.

There was no joy of reunion, no relief of surviving a catastrophe.

There was only one extremely stern military order, as if burning with the last flame of life.

"Team 001! I'm commander number 011! Get out of here immediately! This is a dead end for the Mother Nest! It deliberately left my heartbeat alive, waiting for you to bring over the final, fundamental protocol of the Great Wall to fill its evolutionary gap! Get out—!"

Inside the 013 casualty ward, Jiang Yu's eyes were bloodshot with rage.

Fourteen years of hardship and the resolute decision to cut off his own arm only resulted in the captain suffering a humiliating fate worse than death.

"ah--!"

He let out a beastly roar, suddenly drew the high-frequency cutting gun from his waist, and was about to rush out of the carriage to fight for his life.

A cold hand pressed firmly against his shoulder.

Tang Lan appeared behind him unnoticed, pressing him firmly against the cabin wall with all her might. With her other hand, she drew her gun, the dark muzzle pressed directly against Jiang Yu's chin.

"The lead vehicle didn't issue a ceasefire order," Tang Lan's voice was cold and devoid of emotion, "You don't even have the right to die!"

The mother nest has fully awakened.

The reaction tank below was boiling violently.

Hundreds of giant, living metal tentacles, each over two meters in diameter, erupted from all directions, forming a net that lashed out at the Devourer!

The anti-living contamination force field of the 005 protective compartment can only maintain an absolute safety zone of seven meters around the rear of the vehicle, which is far from enough to cover the entire massive train formation.

The cold, detached broadcast of the mother nest system echoed throughout the void.

"Detected the ultimate authority carrier of the Great Wall. Transfer authority to the commander. Transfer authority to the core of the mountain-suppressing system. Otherwise, crush."

Su Yuan sat in the driver's seat, showing no sign of backing down.

Instead of retreating, he pushed the power rod of the Zhenshan core into the 140% overload red zone!

The newly installed high-frequency oscillating shovel at the front of the vehicle was instantly overloaded and turned completely red-hot.

He issued a chilling order over the vehicle's public address system.

"013, lock on! Open all eight cables and hook onto the rock face! Aim the excavator at the base of the tower—ram it! Pull the tower and the people out together!"

The Devourer leaped out of the air from the edge of the rocky cliff!

Eight dark steel cables shot out like harpoons, gripping the surrounding cave walls and forcibly stabilizing the 300-ton vehicle in mid-air.

With its overwhelming momentum, the front of the vehicle precisely cut into the load-bearing pillar at the base of the tower.

"Creak—!"

Amidst the sickening cracking of metal, the entire neural tower tilted violently, and a huge physical gap was torn open in the control network of the nest!

The tower collapsed.

However, the hundreds of neural cables connecting the commander are tightly linked to the reactor at the core of the Mother Nest. If they are forcibly physically severed, the commander will suffer complete brain death within 0.1 seconds.

"Idiot!" the tank commander roared into the radio. "Wang Hu! Fire! Aim at my head! Fire!"

Dead end.

Just then, Qin Yan's knocking sound rang out urgently.

"Use the fake Ji Yun from station 54 to induce false waves! Inject data poison into it!"

Su Yuan instantly understood.

"Small fire!"

The dark gold conduit of the mobile refining furnace popped out again, this time not piercing the mother nest, but directly piercing the thickest nerve trunk of the tower!

Xiao Huo packaged the previously deciphered "pseudo-Ji Yun neural logic" and all the disordered and garbage data generated in the 001 downgraded true brain into a huge data virus package, and violently poured it into the main control network of the mother nest in a massive overflow manner along the conduit!

The massive amount of contradictory data and pseudo-logic instantly caused a "logic deadlock" in the core controller of the symbiotic nest.

All the living metal tentacles froze in mid-air.

A full second.

It was that fatal second!

Wang Hu operated the high-frequency jaws of the heavy-duty lifting boom and precisely cut the last six main cables connecting the vehicle's spine!

Jiang Yu pulled the flexible traction cable from cabin 013 and pulled the train commander into the 017 isolation life cabin just before he fell into the reaction pool below!

Rescue successful!

Without core suppression, the entire nest entered an irreversible, total self-destruction process due to logical conflicts.

The underground rock strata began to collapse on a large scale, and magma violently erupted from the reaction pool.

Su Yuan did not immediately order a retreat.

He ordered the refining furnace to operate at full power, and the dark gold conduits plunged wildly into the already paralyzed broodstock control console and the adjacent uncontaminated concentrated fuel storage tank.

"Drain it!"

In the apocalyptic collapse, the Devourer greedily devoured the highest-grade memory alloy and a massive amount of high-purity fuel rods.

The refining furnace was operating at overload, quickly recasting two completely new things.

"Pangu-type Absolute Barrier Armor Module"

"Mother Nest-level Overpressure Fuel Circulation Pump"

The brand-new armor and heart pump directly replaced the old components of the Devourer that were nearing their limits.

Driven by the brand-new fuel pump, the core of the mountain-suppressing formation emitted a terrifying roar that pierced through the earth's strata, and for the first time, its parallel stability exceeded the theoretical upper limit of 100%!

Despite the falling boulders and lava, the Devourer rose from the ground along the inner ring of the Great Wall behind the Mother Nest, the actual route leading to the surface!

After racing for fifteen minutes, the Devourer used its new armor to smash through the last Great Wall surface isolation gate.

For the first time, blinding sunlight streamed into the driver's cab.

They broke free from the month-long underground darkness and truly entered the legendary, absolutely safe "surface area of ​​the inner ring of the Great Wall".

Inside the 017 hibernation chamber, the weak but steady heartbeat of the 011 train commander finally resumed.

Jiang Yu knelt outside the cabin. This man, who had walked alone in the darkness for fourteen years and even cut off his own arm, buried his head on the cold deck and wailed.

However, the radar did not flash the green light that signifies safety.

Instead, it emitted a long, piercing cry that was extremely harsh.

Su Yuan looked up at the boundless wilderness in front of him.

There were no survivors there, no homes.

Only tens of thousands of heavily armored steel trains of the old Blue Star expeditionary force, like a black steel jungle, stood there silently.

The moment the Devourer broke in.

Ten thousand blinding blood-red headlights lit up simultaneously.

Tens of thousands of cold, heavy train gun barrels turned in unison, locking onto the battered steel behemoth.

On the main control screen, a line of cold, blood-red characters flashed out.

"Identification complete. Illegal virus carrier 001 has entered the network. Initiating the final cleanup protocol."
