Interdimensional science and technology starting from cyberpunk

“You can't possibly break through.”

The red-hot King's Blade easily pierced the larger Landmate. Although the Ultron robots were forged from steel, they were insignificant in the face of Cybertronian weapons with temperatures exceeding 5000 degrees Celsius.

However, the blade didn't so much pierce and destroy the robot as it "smashed" it. With the powerful force of this body, the mass-produced robots were crushed like tofu!

“You think I only have one base?”

Three humanoid Ultron mechs approached from the sky, looking just like Iron Man from Riel's memories. Before they even arrived, they raised their arms, unleashing a hail of bullets that chipped away at the already damaged mech wreckage.

[V: Which company makes these robots? They're so OP?!]

[Riel: Marvel Company!]

The body raised its left hand, using the wreckage of the destroyed robot as a shield. At the same time, the octopus arm pierced the mech's ammunition bay, and missiles were fed into the right hand by the surging mechanical structure. This arm transformed under Riel's control to match the missile's launch requirements.

In just two seconds, the ammunition bay was refilled!

Boom!

The missile barrage destroyed the suppressing aerial mechs. V controlled Riel, throwing the wreckage in his hand, smashing it hard into the face of a mech preparing to fire!

The King's Blade pierced the data node center, and Ultron's final voice echoed around the structure:

“Look at the sky, the earth, the sea. My soldiers are endless. You've realized that, haven't you?”

Boom!

Riel jumped out of the explosion, landing like a meteor in front of Christopher's Titan.

Christopher wasn't Riel's best fighter, but he had excellent knowledge and a strong will. Paired with a Titan, his combat ability was also excellent among the pilots.

However, one fist couldn't fight four hands. His Titan was already damaged, with a noticeable explosion gap at the left arm joint, exposing the internal structure and flashing with electricity.

Many Titans were still fighting. Thanks to the cover provided by the excellent "little special forces" from Night City, and Hansen's on-the-spot command, they had gradually advanced and cleared a large part of the steel city.

But when Ultron reinforcements began to appear from the sky, the advance slowed down.

Even relying on cybernetic technology, the human brain still struggles to maintain self-control, to think about and feel how long they've truly been fighting in this hell, to guess their limits, to judge the situation.

Even Hansen was the same: the Unification War launched by Military Tech used many intelligent robots and weapons, so it was also called the Metal War, but the robots that appeared in the entire Metal War were probably not as many as they encountered in this battlefield in one hour!

Explosions were commonplace here, and bullets rained down like rain. He had commanded in the Metal War, but compared to the situation here, he would rather call the Metal War a boot camp!

Not to mention the pilots and Latvian Legion soldiers who actually died, even the Night City residents who only controlled the robots with their minds were losing their minds every minute and second from being unable to withstand the impact!

Boom!

Another data node was blown up by Riel's data blade, but this time the overwhelming firepower completely blocked the way forward. Ultron's voice became increasingly rampant:

“Hahaha, it seems your strange mechs are experiencing combat fatigue. I'm eager to know how you structured their combat algorithms.”

“This will be your grave.”

Ultron existed throughout the entire mechanical hive city, and its voice could be heard from anywhere with a speaker.

But this kind of intimidation was meaningless. The soldiers' ears and hearing implants had already been damaged in the continuous explosions. Eyes, smell, feeling, everything was gradually numbing in the tidal wave of attacks.

All they could do was mechanically load bullets into the chamber, mechanically control the guns to fire... They no longer remembered the feeling of hope and passion. Filling their brains was a numb desire to kill.

But killing creatures gave their brains "positive feedback", killing robots...

There was nothing, only emptiness and uncertainty. All around were flickering electric lights, burning flames, mechanical wreckage, and only fear remained in their hearts:

These are robots, who knows if the robots are really dead or not?

But this war had no more supplies, no reinforcements, and even retreat was not an option.

This was an endless battle.

Just then—

Boom!

A bright trail streaked across the sky, followed by a deafening explosion, completely piercing the canopy formed by Ultron mechs!

And Riel saw what it was:

It was an electromagnetic cannon of extremely large caliber! Hitting the unbreached mechanical hive city from hundreds of miles away!

Astonishment appeared in the soldiers' hearts: they instinctively thought it was some kind of Ultron weapon, but what weapon would explode in its own "body"?!

Even in the afterglow of the nuclear explosion, the explosion seemed extremely dazzling, or rather, it was precisely in the afterglow of the nuclear explosion that the trajectory of the electromagnetic cannon shell was so clear.

That was not an Ultron weapon at all, but a shell fired from the opposite direction, it was—

Reinforcements!

As if to confirm what they were thinking, a barrage of missiles pierced through the smoke and struck the interior of the mechanical hive city. Ultron's mocking voice disappeared.

Someone was bombing Ultron's mechanical hive city from the opposite direction, from even further away!

Latest⊥Small⊥Say⊥In⊥Six⊥9⊥Book⊥Bar⊥⊥First⊥Release!

Whoosh—

Missiles came from the sky, Riel stood still, and the scanner barely captured the supersonic support coming through the air, clearly marked with the manufacturer's logo:

“Atlas Group”!

Boom!

The chain of explosions and artillery fire completely destroyed the Ultron robot formation, but even more striking was that most of the mechs began to turn their flight direction and fly in the opposite direction.

It really was reinforcements!

“Those rats—how is this possible!”

Ultron's voice sounded uncontrollably. Riel quickly killed through the defending mechs, and the data blade took advantage of the gap to stab directly into the data center's cables.

With just a nanosecond-level oversight, Riel completely penetrated Ultron's network defenses. By the time Ultron reacted and attempted to physically cut off the connection, an area of two kilometers around was under Riel's control.

All Ultron artillery in the area was redirected and locked onto the mechs.

In just a few seconds, the roaring shells and autocannons completely cleared all the mechs in the area!

Transport planes bearing the flags of the African Union and the Atlas Group streaked across the sky, and countless humans descended from the sky. All the Latvian soldiers could see, could understand:

Those were their allies!

The anti-aircraft turrets in the mechanical hive city turned to the sky in unison!

But in the next second, Riel exerted force with both feet and jumped high into the air, carrying terrifying kinetic energy and directly smashing the turret out of alignment. The gun barrel immediately aimed at another turret.

Boom!

On the turret billowing black smoke, Riel raised his arm high and pointed to the sky. Even though many soldiers might have lost their hearing, he still raised his arms and shouted:

“United as one!”

In the cleared battlefield, the soldiers seemed to freeze. Silence interrupted the endless battle, and this fleeting respite allowed their brains to begin to recover from numbness:

They could win.

They were about to win!

“United as one!”
