As Noah's command was issued, the gauss rifles of the 80,000-strong Mechanical Legion simultaneously emitted the high-frequency hum of charging.
The electromagnetic acceleration rails inside the barrels glowed with a faint blue light, and the green indicator light for hunting mode instantly switched to the blood-red attack mode identifier.
Unlike hunting mode, where attacks primarily focused on precise kills to preserve the integrity of the prey, after removing hunting mode, the gauss rifle began to prioritize high damage, or rather, large-scale destruction.
Now, every shot from the gauss rifle could instantly pulverize a ork into the finest dust imaginable.
"Attack protocol activated, annihilation mode initiated," a crimson skull icon flickered continuously on the Servo-Automaton's tactical visor.
"Electromagnetic acceleration rails overloaded to critical value, projectile mass compensation system offline."
The next second, the air on the battlefield was utterly torn apart.
"Boom!"
It was no longer the soft "whoosh, whoosh" sound of hunting, but a deafening roar.
Thumb-thick depleted uranium slugs accelerated to 0.3 times the speed of light in a million-gauss magnetic field, their surfaces generating tens of thousands of degrees of heat from friction with the air, leaving a plasma trail dozens of meters long in their wake.
The first ork hit didn't even have time to scream.
The instant the projectile made contact with its skin, the terrifying kinetic energy directly vaporized it into a plasma state.
The aftermath carved a hundred-meter-long molten gully across the wasteland, and over thirty orks along the path exploded into a bloody mist as if struck by an invisible giant hammer.
The high temperature generated by the bullets as they passed through these orks also simultaneously destroyed all their spores.
Completely denying them any chance of survival, and any chance of re-propagation.
The entire battlefield became a meat grinder.
Flesh reduced to elementary particles couldn't even grow spores.
The Waaagh! energy field was a joke before the absolute energy suppression.
However, these orks were, after all, a race that loved to start a Waaagh!, so none of them retreated, still surging towards Noah's army like a tide; they knew no fear, only desiring a fierce battle.
But it was clear that once Noah had made the decision to abandon using them as food, these orks had no chance of survival.
Soon, after half an hour of encirclement, the ork army of over 2.6 million was completely annihilated.
In the ravaged battlefield, only that enormous construct made of scrap metal remained.
The Mekboy on it had long been eliminated.
The Mechanical Legion began to process the battlefield, preparing to eradicate all the surrounding spores.
Although this mushroom production area was to be preserved as a food farm, all the green organisms around the living quarters had to be dealt with.
This was to prevent them from regrowing within the shelter and affecting the studies of the young children Noah was now preparing to educate.
Moreover, the Legion had its own tasks to perform, and Noah naturally had his own matters to attend to; he was pondering over the ork construct, trying to figure out how it moved.
After he had eliminated that entire ork army, this massive mechanical construct ceased to move.
To him, it was a pile of scrap metal, and indeed, under his manipulation, it truly was just a pile of scrap metal.
It was as if the towering, attacking ork war machine that had stood before was not this pile of scrap metal he was now looking at.
No matter how Noah thought about it, he found it difficult to connect this pile of scrap metal with the entity that had previously destroyed over 30 of his civilian Servo-Automatons.
"What exactly is this thing? Why does it stop moving when I try to study it?"
Noah muttered to himself.
He had originally thought that if he could research this technology, he could utilize the waste he had discarded.
After all, while the federation's army was powerful and its weapons formidable, they still required a large amount of materials for manufacturing.
In contrast, these orks could create such a thing from a pile of junk, which naturally interested Noah, as it could greatly reduce his expenses.
However, after some time researching, he eventually had to give up on the idea.
Was it that he was useless and truly couldn't figure out how the orks managed to make such a massive contraption move?
No matter how Noah calculated the energy output, it was insufficient to power such a large machine, let alone enable it to wield weapons.
Noah stood before the war machine, now a pile of scrap metal, his brow furrowed.
His fingers traced the rusted exterior, psionics permeating every gear and circuit, yet he still couldn't find any reasonable explanation.
"This isn't scientific..." he muttered, kicking a twisted cannon barrel. "No sufficient energy output, no logical transmission structure, it doesn't even obey basic laws of physics..."
The more he thought about it, the angrier he became, the angrier he became.
In his frustration, he snatched a soldier's lasgun from nearby and fired a shot at the scrap metal, completely melting it into a puddle of liquid.
Afterward, still not placated, he used his psionics to mold the molten metal into a sphere and then angrily hurled it towards another ork encampment.
"I'm so angry!"
"I thought I had found something useful. I should have just blasted it to pieces earlier.
It even caused me to lose so many combat robots! Do you know how much that costs? Damn it!"
Noah gradually became somewhat foul-mouthed.
However, there was still good news, as he had indeed cleared this plain, and now he could build a city here.
He retrieved a large number of engineering robots from his spatial pouch and issued them a command.
"Dig down 100 meters and build a city underground."
Still, the same old saying: he was just one person now. Although he had a Mechanical Legion, a Mechanical Legion was not enough for an interstellar civilization.
To ensure he didn't conflict with the Imperium of Man, he would rather build his small town underground first.
With the powerful federation technology, he could create an environment underground that was just like the surface, or even better than the natural environment on the surface—this was the technology of the Terran Federation.
After all, the civilization outside was definitely an interstellar civilization. Although their weapons seemed so ugly and crude, no one could say that an interstellar civilization didn't possess warships.
Perhaps this civilization was simply not adept at ground warfare?
This was also possible, as he clearly remembered that during the Terran Federation's development, under the leadership of the Grand Marshal, the federation's army for the first 100 years was notoriously incompetent.
That year, the federation's army deployed 10 legions to attack a primitive Bronze Age world, but the result was that the ground forces were wiped out as soon as they landed.
And afterwards, the enemy even brought out a large number of magic airships, leading to a large-scale aerial battle with the federation in space.
That incident was not an isolated case; a federation observation space station was once poked down by a primitive civilization with a spear. Honestly, the entire federation was shocked at the time.
It was precisely because of several such lessons that even though the federation was now in another universe, it remained cautious.
Who knew if some bizarre thing might exist on an inconspicuous planet?
As a Scientist of the federation, Noah naturally inherited the federation's caution.
He also didn't know how abnormal the Imperium of Man on the other side was, so he chose to be cautious first, as he no longer had the federation backing him.
He couldn't act as he used to.
The engineering robots began to work, and Noah sat alone on a rock, feeling lonely. He missed home, he missed the federation.
Being here alone, he didn't even have anyone to talk to, only these cold robots... When he was exploring outside the federation's control range in his exploration spaceship, he could at least connect to the federation's network to watch dramas or play games.
No matter how far he went, he could communicate with his family, which greatly alleviated his loneliness. But now, all of that was gone.
Even the federation itself no longer existed, and Noah felt a bit depressed.
As a researcher, even he could live for over 100,000 years, so how could the federation be eradicated in the long river of history?
This was impossible!
Additionally, he couldn't seem to find the Empty Realm in this universe, and in the Warp, there was a continuous stream of polluting energy rushing towards his body.
Although it was intercepted by his small device and purified by his psionics every time, it was truly annoying.
It was like wanting to eat a meal, but the meal was contaminated with feces—disgusting.
So, no matter how much Noah denied it or tried to comfort himself,
He knew he had probably run to another universe, which was a very tragic piece of news.
To return to his own universe, he would have to build a civilization as vast as his previous federation and then develop technology; only then would it be possible.
He wanted to go home...
