Reborn as a Hated Noble Family, We Start an Industrial Revolution-Chapter 104: The Last Steel Line

The North Sea had traditionally been a symphony of rhythmic waves crashing against the obsidian cliffs, a sound of natural ferocity that had defined the North for eons. But today, that primordial music was buried beneath the discordant roar of heavy steam engines and a sickening, mechanical rhythm that vibrated through the very marrow of the earth. At the Northveil coastline, a thick, emerald-green fog—the necrotic byproduct of Rudigor’s neurotoxic steam bombs—crept across the jagged rocks like a starving ghost. The gas was not merely a death sentence for human lungs; it possessed a vile, corrosive property that gnawed at unprotected mana-circuits, causing them to flicker and hiss in a desperate struggle for survival.

At the absolute front of the line, standing upon the cold iron hatch of a Titan MK-1 tank, a massive, broad-shouldered silhouette stood defiant. Garrick, the man once known throughout the underworld as "The Butcher," stood clad in a suit of heavy reinforced plating adorned with the snarling wolf of House Sudrath. He was no longer a mere mercenary fighting for the cold glint of gold; his loyalty to the Sudrath bloodline had taken root as deep as the foundations of Iron Hearth Castle itself. In his hands, he gripped a heavy machine gun that had been modified with a mana-cooling jacket, the barrel already glowing with the latent heat of a thousand rounds.

"Masks on, you bastards! If I see a single one of you keel over because you decided to take a breath of that green filth, I’ll personally kick your useless asses back to Iron Hearth!" Garrick roared, his voice amplified by the tank’s external intercom, cutting through the heavy hiss of the encroaching fog.

His command echoed with a grounding authority. Around him, the infantrymen—men who had seen their homes burn but refused to let their spirits follow suit—quickly donned their Mana-Gas Filter Masks. These were insectoid-looking devices with emerald mana-crystals embedded in the filters, designed to neutralize toxic particulates through a localized purification field.

However, the fog was a suffocating wall. Visibility had plummeted to a measly ten meters, turning the battlefield into a claustrophobic nightmare of shadows and sound. Amidst that growing despair, a sudden, violet radiance began to pulse from the heights of the Northern Bastion situated on the plateau above.

"Look up!" a soldier screamed, pointing toward the cliffs.

At the summit of the bastion’s primary spire, Lady Raveena Sudrath stood at the epicenter of a gargantuan magic circle that rotated in the air with a hum of absolute power. Her long hair billowed wildly, caught in the updraft of her own mana-surge. Beside her, a dozen military mages stood in a geometric formation, their hands outstretched toward the heavens.

"Atmospheric Circulation... ACTIVATE!" Raveena’s voice, crystalline and sharp, resonated through the Magitech amplifiers.

In an instant, a violent vortex of wind erupted from the bastion. The air didn’t just move; it roared downward like an invisible tidal wave, slamming into the emerald neurotoxin and forcing the gas back toward the sea. Though it couldn’t entirely erase the fog due to the sheer volume being produced by the continuous bombardment, the coastline was suddenly cleared enough for the defenders to see the horror they were facing.

"Thank you, Princess," Garrick grunted, narrowing his eyes. Now, he could see the sight that would haunt his dreams for years to come.

Hundreds of flatbed landing craft from the Iron Empire had reached the shallows. Their massive frontal ramps slammed into the water with a sound like a thunderclap, and from within their dark holds, a tide of Junk-Cyborgs spilled forth. They moved with a terrifying, rhythmic precision, some walking underwater where the waves were too high, their iron bodies indifferent to the salt and the cold.

Beside Garrick’s tank, another Titan MK-1 lurched forward, its sixty tons of weight pulverizing the beach rocks beneath its heavy iron treads. The commander, a man with a jagged mining scar across his cheek, popped his head out of the hatch.

"Sergeant Kaelen, reporting for duty, Captain Garrick! Sector 4 Titan Unit is ready for your command!" the man shouted, offering a stiff, soot-covered military salute.

Garrick turned to the newcomer, a grim smirk playing on his lips. "Kaelen! I need your steel on the left flank. Do not, under any circumstances, let those scrap-heaps reach the civilian evacuation routes. We are the only thing standing between the people of Northveil and their chainsaws!"

Kaelen nodded, his eyes cold and analytical as he surveyed the sheer mass of the incoming swarm. "Understood. We will be the wall."

"ALL TITAN UNITS! LOCK SENSORS!" Garrick commanded, his voice a low vibration of intent.

The crimson optical sensors on the Titan MK-1 turrets glowed like the eyes of predatory beasts. This was Rianor’s masterpiece—a machine that combined the raw combustion power of Earth’s engineering with the sophisticated energy-projection of mana-circuitry.

"Open fire!"

BAM! BAM! BAM!

The main cannons of the Titans didn’t fire conventional gunpowder shells. They spat concentrated mana-slurries that detonated with a brilliant blue flash upon impact. At the front of the enemy line, dozens of Junk-Cyborgs were disintegrated, their mechanical limbs and gear-riddled torsos thrown into the air like scrap metal in a windstorm. But the numbers of the Empire were seemingly infinite.

"They’re still coming! Captain, they’re initiating rocket-fire!" Kaelen shouted.

From the enemy landing craft, small Air-Bomber units launched from steam-catapults began to dive-bomb the beach. They released volleys of steam-propelled rockets that hissed through the air with a high-pitched, terrifying whistle.

"Engage Point-Defense Lasers!" Garrick barked.

Atop each Titan unit, a secondary turret spun with mechanical speed. Thin, red laser beams lanced through the air, intercepting the rockets in mid-flight before they could touch the tanks’ armor. Explosions blossomed in the gray sky, creating a macabre firework display of death amidst the ashen clouds.

"This isn’t enough!" Garrick realized the enemy was beginning to cluster at the Sector 4 bridge—the primary artery for the civilians still trapped in the lower sectors. "Kaelen, switch to Mana-Lock Rocket pods! Sweep the shoreline!"

The automated systems of the Titan MK-1 hummed as they reconfigured. Side panels on the tanks slid open, revealing racks of small missiles etched with heat-seeking mana-runes. Within seconds, dozens of rockets spiraled into the air in a graceful, lethal arc, chasing the heat signatures of the steam-reactors on the cyborgs’ backs.

BOOM! BOOM! BOOM!

The shoreline was transmuted into a literal hell. Jagged iron fragments, boiling machine oil, and superheated steam erupted in every direction. Yet, the arrogance of the Iron Empire was absolute; they didn’t care how many units were pulverized, as long as they could gain a single meter of ground.

Several Junk-Cyborgs that had managed to survive the rocket barrage began to scale the hulls of the Titans, their iron claws screeching against the reinforced armor.

"Get off my baby, you rusted filth!" Garrick roared, hoisting his heavy machine gun. He fired from his open hatch, saturating the cyborgs trying to sabotage the tank’s communication arrays with lead. His mana-infused rounds punched holes through their iron skulls, spraying black hydraulic fluid across Garrick’s face.

He wiped the foul-smelling grease from his eyes, his gaze flickering toward the residential district behind them. Thousands of Northveil civilians were still desperately scrambling into the final evacuation trucks. Caelus, Ramirez, Raphael, and their respective teams were working themselves to the point of collapse to maintain order. If the defense at this beach failed, Northveil would be turned into a slaughterhouse within minutes.

"Remember why we’re standing here!" Garrick’s voice resonated through the radio channels of every Titan crew. "We aren’t fighting for this mud or these rocks! We’re fighting for the hearts beating behind us! If you have to die today, make sure you die on a mountain of their corpses!"

The morale of the tank crews flared into a desperate, burning fire. Sergeant Kaelen steered his tank directly into the thick of a cyborg cluster, using the sixty-ton weight of the machine to grind them into the sand. The sound of metal snapping and steam-pipes bursting was a rhythmic, industrial crunch beneath the iron treads.

In the distance, atop the bridge of The Emperor, General Rudigor observed the carnage through his optical sensors. "Such persistence. Knights who hide behind iron plates... intriguing. Deploy the Breaker units. I wish to see how their ’modern’ armor fares against the pressure of pure, unadulterated steam."

Suddenly, the sea near the Sector 4 bridge erupted. Three monolithic shadows emerged from the churning water. These were not standard Junk-Cyborgs. They stood four meters tall, clad in massive plates of iron etched with crude anti-mana runes. Their right arms had been replaced by gargantuan sledgehammers powered by high-pressure steam-pistons.

"Captain! Heavy units in the water! Class-A Breakers!" Kaelen’s voice crackled with a new note of alarm.

Garrick stared at the new monsters. One of the Breaker units slammed its massive hammer into a Titan MK-1 on the left flank.

KRAAAKKK!

The frontal armor of the tank, which was usually immune to conventional shells, crumpled instantly like a tin can. The mana-circuits within short-circuited, triggering an internal reactor explosion that incinerated the entire crew in an instant.

"Damn it!" Garrick growled, his eyes turning a bloodshot red. "All units, concentrate fire on the giants! Use Armor-Piercing Mana slugs! Now!"

The battle shifted into a state of visceral brutality. The engagement range was now measured in meters. Sudrath infantry began to spill out of the trenches to protect the tanks’ undercarriages from smaller cyborg saboteurs. Knights with Magitech spears thrust their weapons into the gaps of the cyborgs’ plating, while mana-archers rained shafts of concentrated light into the enemy’s optical sensors.

Raveena, atop the bastion, continued to force her mana into the wind-vortex. Cold sweat ran down her forehead, her vision beginning to blur from the strain. "Just a little longer... I must hold the gas back..." she whispered to herself. She knew that if she faltered, the neurotoxin would flood the beach and paralyze Garrick’s remaining forces in seconds.

Amidst the cacofony, a static-choked radio transmission reached Garrick’s ears. It was Rianor, his voice cold, stable, and utterly detached.

"Captain Garrick. This is Rianor. I am monitoring the heat signatures through the observation facility. You have a window of three minutes before the second wave makes landfall. Withdraw to the Bridge immediately. I am ordering a Grimm’s Roar barrage to cover the shoreline."

Garrick looked at his depleted forces. Out of his original hundred Titans, barely forty were still operational. The infantry casualties were climbing at a staggering rate.

"Young Master, we can still hold them here! We can break their back at the water!" Garrick protested, his pride as a soldier flaring.

"This is an order, Captain," Rianor’s voice was absolute. "If you stay on that beach, you will be trapped when the river begins to overflow due to the Dam’s structural failure. Retreat to the bridge. Form a Phalanx there. Protect the civilian evacuation. That is the only priority that matters."

Garrick clenched his fist until his knuckles groaned. "Understood. You heard the man, you bastards! Fall back to the bridge! Maintain formation! Do not let a single one of those scrap-heaps through!"

The Titan units began a fighting retreat, firing their cannons as they reversed. Sergeant Kaelen took the rearguard position, using his tank as a literal shield for the others whose ammunition was running dry.

As they reached the base of the bridge, a high-pitched, shrieking whistle descended from the sky far behind the city.

WUUUUUUUSHHHHH—BOOOOOM!

the gargantuan coastal cannon, Grimm’s Roar, had spoken. The 400mm projectile struck the shoreline exactly where they had been standing minutes ago. The explosion created a massive crater and vaporized hundreds of cyborgs instantly, the shockwave causing even Garrick’s heavy tank to shudder.

"Good shot," Garrick murmured, watching the pillar of fire rise from the sand.

But amidst the smoke of the blast, the massive Breaker units were still standing, though their iron plating was tattered and bent. they began to walk slowly toward the bridge, followed by thousands of red optical sensors emerging from the sea like a rising tide of blood.

Garrick climbed down from his tank’s hatch, standing on the asphalt of the bridge with his heavy machine gun still steaming from the heat. Behind him, the final thousands of civilians—children, the elderly, and women—were being shoved into the last transport trucks by Prince Caelus.

"Kaelen! Everyone who still has a hand to hold a weapon!" Garrick shouted, staring at the endless horizon of enemies. "We won’t win today! But we will make sure that today, our deaths actually mean something!"

The snow began to fall again, mixing with ash and machine oil. Beneath the dying sky of Northveil, Garrick and the remnants of his iron unit formed the last line of defense. They were a thin, steel wall keeping the heart of Northreach from stopping today. The true battle had only just begun, and the scent of death in the air was now mixed with a resolve harder than any iron.
