Chapter 233: The Mobile Warrior that Hunts Nuclear Submarines

The Wind Element Civilization was one that served the Natural Selection unconditionally.

Although composed of wind, they were far from gentle like the wind.

Conversely, the Fire Element Civilization, which ought to have been the most violent, remained surprisingly disciplined.

The Wind Elements stormed into the Underground City, engaging in unrestrained combat.

Rather than calling it combat, it was more akin to a one-sided massacre.

Under the assault of the Wind Elements, the Arachnid Demons fell in droves.

Some Arachnid Demons, driven by sheer terror, knelt and begged for mercy.

The Wind Elements ignored their pleas and continued the slaughter.

It wasn’t due to a bloodthirsty nature, but because the Monstrous Forces had issued a direct order when launching the punitive expedition.

“Exterminate the Arachnid Demon Civilization. Leave not a single one alive.”

When all the Wind Elements suddenly ceased their assault and collectively ascended to the cavern ceiling, the surviving Arachnid Demons witnessed the most horrifying sight of their lives.

The Wind Elements transformed into countless streams of airflow, converging into an unprecedented overpressure storm that surged toward the Underground City.

It poured in through every crevice of the city like an invisible flood, sweeping through the vast structure. The Arachnid Demons, their architecture, and even the structural foundations of the Underground City were torn apart and obliterated.

With the conclusion of the cleansing, the war ended.

Tens of thousands of Arachnid Demons were annihilated. Wind Element casualties: zero.

The overpressure storm dispersed and reverted into countless Wind Elements once more.

“Continue the advance,” the leading Wind Element general ordered coldly.

The Wind Element Civilization served as the absolute main force in the punitive expedition, tasked with storming the Capital and executing the Arachnid Demon king and the entirety of its upper ranks.

15,000 meters deep within the Underground Kingdom — Capital of the Arachnid Demon Civilization.

The Arachnid Demon King Ozuma sent yet another figure away from the royal palace.

That figure wasn’t a monster — it was a human.

A special envoy from the world-class organization Titan Throne.

The envoy turned back to look at the Arachnid Demon King standing before him.

He had come this time carrying a mission from the upper echelon.

To persuade the Arachnid Demon Civilization to surrender and come under the service of the Titan Throne.

The terms offered by the Titan Throne were as follows:

  To preserve the lives of the Arachnid Demon King and a group of high-level officials, along with one hundred thousand Arachnid Demons, who would be extracted from the Underground World via high-grade items and resettled in a specially arranged sanctuary by the Titan Throne.

From that point forward, the Titan Throne would guarantee their safety.

In return, Ozuma and his kin would be required to work for the Titan Throne, producing a series of special silks.

“Your Majesty Ozuma, you know the state of the front lines. Things are no longer in your favor,” the envoy spoke softly. “The Wind Element forces are advancing toward your Capital at full speed. At this rate, the city will fall within days.”

Ozuma smiled and shook his head.

“Thank you for the offer, but there’s no need,” he said slowly.

The envoy had clearly anticipated this response and shook his head slightly.

“You’re choosing to die with your homeland? I can understand your sentiment, and that of your kin, but it’s unnecessary. In this world, survival is everything.”

“Even when attacked by our fellow monsters, the Arachnid Demon Civilization holds firm in its resolve,” Ozuma replied calmly. “The bottom line of our Monstrous Civilizations is to resist humanity. That will never change, no matter the circumstances.”

Seeing this, the envoy no longer attempted persuasion.

“Understood,” he said quietly. “Farewell, Your Majesty.”

With that, his figure vanished.

Ozuma turned and looked upon the Capital before him, a hint of sorrow flickering in his eyes.

Then he vibrated his limbs to summon a close aide, speaking coldly.

“Inform the construction department. Prepare to activate the Web of the End project.”

Southern Ocean, 3,261 meters underwater.

Beneath the ghostly blue depths, a steel leviathan quietly passed through.

Its long, slender silhouette resembled a giant whale, silently traversing this realm of silence.

It was a nuclear submarine from the Monstrous Civilizations.

The scene shifted to the interior, where monstrous crew members efficiently performed their duties, maintaining the submarine’s operation.

A sonar operator, wearing noise-cancelling headphones, curled up before a curved screen, pupils contracting with each anomalous sonar ping.

An engine operator kneeled before the steam pipelines, using a stethoscope-like tool to check the welds.

By the tactical table in the command room, officers communicated through brief hand signals and encrypted terms.

When it came to piloting high-tech vehicles, monsters proved every bit the equal of humans.

To these monsters, today was business as usual.

Continue patrolling the Southern Ocean, and strike once a human Mobile City was found.

But just minutes later, everything changed.

The green ripples on the sonar screen suddenly became erratic. The sonar operator’s fingers froze above the keyboard, disbelief in his eyes.

An abnormal sonar signature had appeared 3,000 meters away.

Not a submarine, nor a whale pod — it was a metal echo that completely defied the laws of hydrodynamics.

It cut through the water along a bizarre zigzag path, rapidly closing in on the submarine.

The monsters immediately reported to their superiors.

Target detected, bearing 1-1-0, depth 3,100 meters, speed 65 knots.

As the tactical screen auto-zoomed on the signal source, the outline analysis system flashed a flurry of alerts.

It was a humanoid robot over 100 meters tall.

The Iron Oath Brotherhood’s Mobile Warrior "Iron Oath MS-UM-K7".

MS stood for Mobile Warrior. UM denoted underwater mobility type. K7 was its model number.

Indeed, only world-class organizations could afford to deploy such numbers of Mobile Warriors — hence the need for identification codes.

A standard Level 4 City would be lucky to produce even one or two.

Inside the nuclear submarine’s command room, the red combat alarms bathed the monsters' faces in a crimson glow.

On screen, the UM-K7 was approaching in a zigzag pattern. Ghostly blue phosphorescence seeped from the seams in its armor, trailing a haunting luminescence through the deep sea.

3,000 meters. 2,800 meters. 2,600 meters…

The distance between them shrank rapidly.

The submarine struck first.

Six dull thuds came from its belly — compressed air launching six heavy torpedoes from their tubes, blooming into six transient bubble-flowers in the inky waters.

Simultaneously, with muffled roars unique to underwater ignition, eight submarine-launched cruise missiles burst from buffered launch tubes. Even before surfacing, they completed vector reorientation. Their solid boosters ignited underwater, roaring like harbingers of death as they broke the surface.

They would fly inertially above water for a time before diving back down to strike UM-K7.

But UM-K7 was ready.

Its supercavitating torpedo launcher fired with a roar, sending multiple intercept torpedoes streaking forward with tight bubble trails, unleashing 140-decibel sonic detonations in front of the enemy salvo.

Three heavy torpedoes were instantly destroyed in a violent cavitation burst.

At the same time, UM-K7’s bubble curtain projector spewed dense chemical bubbles, creating an acoustic smokescreen around it. The remaining three torpedoes’ guidance systems fell into disarray.

Seizing the moment, UM-K7 suddenly drew its high-frequency vibration cutting blade.

A signature melee weapon unique to Mobile Warriors.

It measured 17 meters long, with a streamlined blade forming a perfect reverse curve. Its multi-layer composite construction featured everything from etched carbon-metal coating with fine diversion channels, to a hyper-dense alloy core embedded with hundreds of micro piezoelectric vibration units, and a resonance chamber filled with high-purity helium gas.

Once activated, the blade would resonate at tens of thousands of vibrations per second.

  Normally, this blade was folded and stored within the arm or leg armor of the Mobile Warrior. Once activated, it would spring open instantly, transforming into the trusted melee weapon of the Mobile Warrior.

Seventeen meters was not the standard configuration. Mobile Warriors could customize the blade length as needed. Melee weapons weren’t limited to vibration cutting blades — they included whips, short blades, long swords, and more.

As the UM-K7 swung its blade, the vibration edge traced a perfect arc underwater, slicing straight through a heavy torpedo.

Rather than being sliced, it was more like it shattered. The torpedo twisted and warped as if crushed by an invisible giant hand, its casing shedding like fragile glass.

The outer shell blossomed like petals, followed by a blinding flash from within. When the shockwave reached UM-K7’s armor, the vortex generators on its surface immediately responded, diverting and neutralizing the lethal impact.

The remaining two heavy torpedoes were dealt with in succession.

When the eight submarine-launched cruise missiles arrived, UM-K7 raised its right arm, and the plasma pulse cannon mounted atop it fired continuously. High-energy plasma beams tore through the water, forming ionized channels. Three of the missiles were disabled within this electromagnetic storm, spiraling into the abyss.

Immediately after, the net launcher on UM-K7’s left wrist fired in rapid succession. Specialized ultra-tough fiber nets entangled two of the missiles’ fins, causing them to spin out of control like seabirds with broken wings.

The final three missiles were fooled by decoy heat sources created by the vortex generators, luring them into crashing into the seabed.

The monsters instantly fell into despair.

Among vehicles of the same tier, Mobile Warriors had overwhelming superiority over ships, submarines, fighter jets, and tanks.

It was, in essence, a dimensional strike born from a revolution in military technology.

Mobile Warriors combined mobility, tactical flexibility, firepower intensity, and battlefield adaptability. They could also equip a variety of modular upgrades to operate effectively across sea, land, and air.

Combined with a suite of high-tech weaponry, they were a true nightmare on the battlefield.

Among Level 4 vehicles, nuclear submarines were the overlords of the deep sea, with their weapons and strategic value being self-evident — provided they didn’t encounter a Mobile Warrior.

Otherwise, from the moment combat began, nuclear submarines would be at a crushing disadvantage.

The monsters understood clearly — this was a dead end.

Reloading heavy torpedoes and cruise missiles took time — and even if fired again, they would still be neutralized.

At this moment, UM-K7 was already accelerating at full speed.

As it reached the nuclear submarine, the twin eyes on its head flared with unprecedented red light, and it viciously slashed with its vibration blade.

The moment the blade pierced the submarine’s outer shell, its tens-of-thousands-per-second vibration frequency tore apart the metal structure, crumbling the hull like brittle crackers.

As the blade pierced through the reactor compartment wall, the ruptured coolant pipes sprayed high-pressure steam that condensed into white plumes in the deep sea.

With a sudden upward slash, the vibration blade carved a deadly wound dozens of meters long along the submarine’s keel — like a hot knife through butter. The exposed nuclear reactor groaned under deep-sea pressure as the alloy fuel rods began to uncontrollably fission.

As UM-K7 withdrew its blade, the entire submarine broke in half like a pencil snapped by an invisible hand, accompanied by the wailing distortion of metal.

The Mobile Warrior’s glowing red eyes faded into a ghostly blue. Its high-frequency vibration cutting blade slowly retracted into its arm armor, emitting a cold metallic clink.

Fragments of the submarine’s hull clinging to the blade peeled away under deep-sea pressure — like a snowfall of black flakes.

As UM-K7 departed, the submarine’s remains exploded. The nuclear fireball contracted under the crushing weight of tens of thousands of tons of seawater, forming a bizarre bluish-green sphere.

And it wasn’t just here — across many regions of the Southern Ocean, Mobile Warriors from the Human Forces were hunting and destroying the Monstrous Forces' nuclear submarines.

From now on, the waters of this ocean would be much quieter.

Polar Continent, Tundra Zone, Ice Dome Research Base.

After carefully considering his words, Li Ye slowly spoke to Bishop Heath.

“Bishop Heath, the Arachnid Demon Civilization has existed for over two hundred years. It’s possible they built something massive in the Underground World.”

Heath paused, momentarily stunned.

“Speaking of massive construction, isn’t the Underground World itself one? In fact, I was quite surprised myself — never thought the Arachnid Demons could build such a vast network beneath the Polar Continent.”

“No, that’s not what I meant...” Li Ye shook his head slowly.

Just then, he suddenly noticed something.

It was a pile of explosive silk, war spoils seized by a Level 0.5 Mobile City from the Underground City.

Because of its volatile nature, they had gone out of their way to store the explosive silk in explosion-proof containers before bringing it in.

Li Ye stared at it, momentarily stunned.

An Underground World spanning the entire Polar Continent.

A project the scale of a continental megastructure — the Web of the End.

Explosive silk.

These three points converged in his mind like merging light dots.

As he returned to his senses, his body trembled slightly.

“Land Collapse! The Arachnid Demon Civilization intends to collapse the entire continent!”

He cried out urgently.

“Bishop Heath, we must evacuate all troops!”

Heath froze in shock.

And not just him — his subordinates, Lin Mei, Oleg, and the surrounding researchers all turned to stare at him.

“To sink an entire continent — how is that even possible...” Heath trailed off.

Wasting no time, Li Ye immediately recalled the Level 0.5 Mobile City he had deployed.

After doing so, he quickly explained his theory.

The Arachnid Demon Civilization had deployed vast quantities of explosive silk at multiple critical support nodes in the Underground World. By remotely triggering them via silk-based detonation, they could collapse these nodes, triggering a domino effect throughout the Underground World.

As the Underground World collapsed, the surface of the Polar Continent would sink and disintegrate.

After hearing Li Ye’s explanation, a chill unlike anything before swept through everyone.

Lin Mei immediately rushed to a nearby computer, inputting the scale of the Underground World and Li Ye’s collapse predictions into the system, initiating a simulation.

A few minutes later, the computer produced the result.

There was a 74% probability that the entire Polar Continent would sink.
