I Became a Genius Mechanic at the Academy

---

World Tree.

After incorporating the World Tree as an ally, Edgar devised a plan.

He wanted to utilize the countless souls trapped within the World Tree like a ‘supercomputer.’

Because even running a single airplane requires an air traffic control tower, which employs numerous humans to assist in operations.

In other words, he aimed to establish a framework for ‘remote control.’

[Aaaaaaaah! I won’t do it! It feels like my head’s going to explode!!]

However, that plan fell apart.

After all, the souls inside the World Tree were people, not machines.

They refused to learn ‘physics’ and ‘basic mechanical engineering.’

To the Elf Ancestors, who had spent thousands of years using spirit art and natural magic, the physics that Edgar was trying to teach was akin to an alien language.

“I guess I have no choice. I won’t force physics on you anymore.”

Thus, Edgar decided to step back.

Even with just a 10-year gap, generational conflict could arise, and teaching modern knowledge to the Elf Ancestors who had accumulated wisdom over thousands of years was an impossibility.

It was like telling grandparents who had never played a video game to reach a rank of League Challenger in a game.

Such was a harsh and unreasonable request.

“Instead, please assist us in what you excel at. Modern descendants need you.”

Therefore, Edgar encouraged the Elf Ancestors to freely engage in their strengths.

As a result, the souls residing within the World Tree began to shine brightly.

“If that’s the case, wait a moment. If all the souls here combine their efforts, we might be able to recreate ‘Isloberten.'”

“Is, Isloberten!”

As the giant Elf spirit mentioned the name ‘Isloberten,’ the other Elf spirits began to resonate with it.

Edgar asked what Isloberten was.

The Elf spirit who initially mentioned the name answered.

“In the language of Elves, it means ‘King of Golems.’ Though it is currently considered a myth, I assure you that he existed during my time. A colossal golem that seemed as if the mountain itself was moving.”

A golem of such enormous size that one could mistake it for a mountain itself.

Edgar couldn’t help but smile.

He remembered that golem too.

It came down to this land thousands of years ago, engaging in the ‘Genesis War’ with the Grand Duke.

At that time, Isloberten was a golem that had gained its consciousness from the powers of the Heavenly Beings.

And Edgar knew very well about Isloberten’s tremendous power.

“Yes, then I leave the golem to you.”

Thus, Edgar entrusted the resurrection of Isloberten to the Elf Ancestors of the World Tree.

He then began developing a super colossal suit to enhance Isloberten.

While Isloberten’s inherent power was formidable, if a suit was added, its strength could multiply several times over.

-Kugugugugugugugu!

As the moment arrived, Isloberten, born from a multitude of golems, made its appearance.

A gigantic golem towering 182 meters tall, fully equipped in a mechanical suit, emerged onto the battlefield.

Numerous crowds at the defensive wall gazed up at the titanic Isloberten in awe.

-It’s on a whole different scale… That incredible… mountain…

-It’s Count Fix, who constantly surprises us, but this time it’s a whole different level…

-Could such a weapon actually exist…? It feels like the myth of the Genesis is coming to life…!

The crowd marveled at the massive mechanized warrior ‘Titan’ born from the collaboration of the World Tree and Edgar.

For them, the great mechanized soldier ‘Titan’ was a being that inspired awe.

A massive mech towering twice the height of the Statue of Liberty, striding across the battlefield while clad in a sleek, black suit, it evoked an inherent sense of reverence.

[Islo, wipe them all out.]

[As you wish.]

However, Edgar issued commands to that being as if it were nothing.

After all, the one who created Isloberten was a Heavenly Being, and the leader of the Heavenly Beings was Edgar.

Thus, Isloberten, manifesting on this land through the will of the World Tree, naturally obeyed Edgar’s commands.

Soon, Isloberten hurled the ‘Spear of Titan’ deep into enemy territory.

-Kugugugugugugugugu!!!

A deafening sound echoed throughout the space, like the tearing of heaven and earth.

The destructive light following the spear’s trajectory filled everyone’s vision, illuminating the night sky.

It felt as though the spear contained the omnipotent destructive power akin to Zeus’s spear plunging into the ground.

-Kwaaaaaaang!!

And indeed, that destructive power met expectations.

An overwhelming force that annihilated everything within a radius of 20 meters.

This was a level of destruction that even a High Demon could not withstand.

The inherent strength of Isloberten and Edgar’s mana engineering surpassed the energy threshold that even High Demons could endure.

[…I will face that one.]

Thus, the highest-ranking demon born from the fusion of 12 Death Knights, the ‘Knight of Calamity,’ stepped forward.

The Knight of Calamity, towering at 17 meters, commanded its subordinates to grow larger in order to confront Titan.

[We are the ilk of Lilith, created to consume the new world. Once I surpass Edgar Fix, the world will belong to us. I will take care of Edgar Fix; the rest of you handle that hunk of scrap.]

[Krooooooooh!]

The demons began to rampage.

Even the beleaguered remnants of the Frost Orcs, who had once retreated in fear, were now unleashing their destructive urges under the mental domination of the High Demon.

Hatred and wrath brewed in every corner.

[Slaughter the enemies!]

[Kyaaaaaaah!!!]

Soon, a vast number of demons flooded from the enemy ranks.

Though their numbers were dramatically reduced by the nuclear weaponry, the sheer quantity of demons still overwhelmingly surpassed the allied forces.

“Fire!”

At that moment, someone standing at the center of the mechanized unit gave the order to fire.

That order came from David, the club president, who had climbed up to be Edgar’s right-hand man.

The second-in-command, Anthony, also began issuing tactical commands to the soldiers as the commander of the mechanized unit.

-Bang! Kwa-kwa-kwaang! Bang!

Then, flames erupted from the tanks lined up in the front row.

Shells were fired from the barrels of K-1 tanks, engineered through a fusion of magic engineering and modern technology.

-Swoosh! Shoo-shoo-shoo-shoo!

Moreover, that wasn’t all.

Edgar had meticulously prepared for this war.

In particular, he had invested great effort into the mechanized unit operated under the leadership of the club members.

For this reason, various types of tanks, including medium tanks, heavy tanks, assault tanks, and self-propelled artillery, were fully stocked, creating a spectacular display of firepower.

-Bang! Kwa-kwa-kwaang! Kwa-kwa-kwaang!

It was truly a majestic scene.

Steel rain blanketed the sky, striking the enemy’s ranks and splattering demon blood and flesh in all directions.

[Kyaoooor!]

However, even amidst this tremendous barrage, there were still demons approaching the mechanized unit.

The sheer number of demons was simply too great.

“Assault Mechs, forward!”

Yet the mechanized unit had Assault Mechs to compensate for the tanks’ vulnerability at close range.

Rooted in construction robots, the Assault Mechs were armed with machine guns and metal blades, ready to demonstrate their formidable close-quarters combat prowess.

-Do-do-do-do-do-do-do!!!

The demons that pierced through the deluge of steel rain were promptly dealt with by the Assault Mechs.

Furthermore, as regular troops from the Empire and soldiers from the Allied Kingdom joined the fray.

Not a single demon could breach the mechanized lines.

[Tessagi.]

And Edgar watched the spectacle with a pleased expression, murmuring the word ‘Tessagi.’

When Titan asked what it meant, Edgar replied with a cryptic phrase: ‘No one can stop a 200-mech 3,3-up.’

In the meantime, the Knight of Calamity, now fully grown, began to chant some ominous spell.

[Ka-Sec-Betenkhak-Krohk…]

The more the spell was chanted, the greater the massive energy began to gather above its head.

Though the nature of that spell remained unknown, Edgar instinctively felt that they couldn’t let this continue.

Edgar glared at the Knight and said to Titan.

[Darkswarm is cheating. Stop it immediately.]

[…Understood.]

Kugugugugu!

Titan’s colossal form prepared to leap.

Smoke billowed from the various power sources of the suit he was equipped with, and lights flickered on the black armor’s LEDs.

-Whoosh!

Thus, coiling its body tightly, Titan exploded with energy as it soared into the sky.

The direction it was descending towards was precisely where the Knight of Calamity stood.

[You’re coming to die on your own!]

In response, the Knight unleashed the negative energy it had summoned above its head towards Titan.

This negative energy was akin to the ‘Corruption Bullet’ that had melted through titanium alloy barriers.

[Activating Plasma Mana Shield.]

Edgar activated the Plasma Mana Shield.

The Plasma Mana Shield absorbed the damage from the negative energy, successfully protecting Titan’s armor.

[You think a measly shield can block all my attacks!]

However, the Knight of Calamity was not the type to stand idly by.

Born from the fusion of 12 Death Knights, he possessed a strength that could be termed ‘quasi-grand duke’ level.

Moreover, being the strongest subordinate of Lilith, he had been further enhanced by Azazel’s ‘Demonic Wave.’

Immediately, he swung his magic sword, the ‘Corrosive Blade,’ to attack Titan.

-[Chiiiiiiiiiiiiiiiiiik!]

At that moment, the Plasma Mana Shield began to shake unsteadily.

By taking on negative energy and the Corrosive Blade simultaneously, the shield’s power rapidly dwindled.

‘There’s definitely a difference in fundamental tier. Ruthless strength alone can overwhelm Titan…’

Indeed, he was right about the quasi-grand duke level.

Even equipping Isloberten, resurrected from thousands of golems, with a colossal suit was insufficient to surpass the Knight of Calamity.

To compare the difference in tier with a popular Korean folk game, it could be likened to the Ultra Risk hero ‘Torarisque’ facing off against a standard Acan in a 1:1 match.

In other words, in terms of offense, defense, and stamina, everything fell short against the Knight of Calamity.

[Edgar Fix, the will of Lady Lilith shall be realized! I will defeat you here, and then sweep away your pathetic shields and scrap metal army! I’ll especially give you the chance to witness that spectacle!]

Thus, the Knight of Calamity swung his Corrosive Blade with certainty of victory.

With a tremendous sound, the Plasma Mana Shield began to tremble precariously, and soon shattered into countless pieces.

At the moment of contact, Titan’s core vulnerability lay exposed with no defense.

[It’s over! My sword can melt any substance with ease!]

Confident of victory, the Knight of Calamity lunged his Corrosive Blade towards Titan.

Simultaneously, he unleashed the negative energy emanating from within himself towards Titan.

According to expectations, Titan would dissolve under this combined assault in less than 10 seconds.

[Activating Plasma Mana Shield.]

Yet in that instant, the Plasma Mana Shield activated once again.

The Knight’s attack was neutralized as it dispersed harmlessly against the Plasma Mana Shield.

Caught off guard, the Knight stared wide-eyed while Edgar smirked.

[Yeah, you’re certainly stronger. Your tier is indeed higher.]

[…Well…]

[But I’m a shield battery. And I can infinitely refill it.]

Edgar, comparing himself to a shield battery, maintained a triumphant grin.

Just as Edgar had said, he was specialized in the role of a ‘battery.’

In reality, Edgar’s strength was not due to any innate power, but rather the utility and offensive power of the advanced technology suit being activated by the right power input.

Especially, the Doom Suit was capable of drawing out and converting all the emotional energy from each of his turns into physical force, effectively being strengthened not through training but by an ‘Energy Revolution.’

In other words, from beginning to end, Edgar had faithfully fulfilled his role as a ‘human battery’ to upgrade his power.

[So, I’ll hang on relentlessly. Just how far can a powerful, long-lasting battery go?]

Thus Edgar confidently declared.

He dared the Knight to attempt attacking until the shield battery ran dry.

***

[Why!!! Why does the shield keep regenerating!!!]

The Knight of Calamity roared in an aggrieved tone.

It should have been possible to melt Titan in less than a minute, but even after 20 minutes, he couldn’t eliminate it.

[Dieeeeeee!]

It was absurd.

Despite being much stronger than Titan.

The one facing defeat was himself.

All his attacks were being blocked by the Plasma Mana Shield while Titan accumulated its chances to strike back.

[How long does this even last!! Dieeeeeee!]

He felt like he might explode with frustration.

If he didn’t quickly eliminate Titan, his minions would be unable to breach the barrier.

Blocked by Titan, his minions suffered damage nearly to the point of extermination.

It was maddeningly frustrating.

[This is cheating!!!]

This was undoubtedly an unfair game scenario.

Akan with an infinitely refillable shield battery.

It was akin to a battery following behind and replenishing Akan’s shield.

Yet, faced with the impossible circumstance of needing to seriously win against such a bug-riddled game, the Knight of Calamity felt a sense of injustice.

[Ugh… Edgar Fix… One day, if I… am reborn… then, I will definitely… take you…!]

Thus, the Knight of Calamity fell without ever laying a scratch on Titan.

The quasi-grand duke, imbued with the greatest powers from Lilith, had been inconceivably defeated.

-Woooohoooooo!!!

-We did it! We won!

-Fix! Fix! Fix! Fix! Fix!

As the Knight of Calamity collapsed and victory was confirmed.

All the soldiers at the defensive wall rushed out, cheering wildly.

It was a tremendous crisis that could have led to the Empire’s downfall if not for Edgar Fix.

Everyone chanted ‘Fix’ in admiration of him.

And this moment of jubilation was not limited to just the northern defense line.

[Eve, how much did the broadcasting fee come in?]

[…I was surprised how much came in. It comfortably surpassed trillions.]

Eve reported in an excited voice about earning trillions from the ‘broadcasting fee.’

In this way, Edgar used this battle to transmit worldwide, turning it into a means of profit.

He aimed to raise awareness about the dangers of demons to the world while making money – a twofold benefit.

[…Especially the donations are massive. ‘Star Pieces’ totaled several trillion!]

Then Eve mentions how many donations had been made by referring to ‘Star Pieces.’

Here, ‘Star Pieces’ refer to a donation system created by Edgar, gaslighting the descendants of Heavenly Beings into thinking they were ‘descendants of stars,’ akin to paprika TV’s star balloons.

The ‘Star Piece’ system was designed so that anyone could support it at any time if they felt compelled to donate while watching the war.

-Ellian!! Hang in there!!!

-Garcian! You can’t die!

-Our son! Just come back safe! Don’t push yourself too hard!

As a result of creating the Star Piece system.

A massive influx of donations poured in.

Family, friends, lovers, and acquaintances of the participants in the war.

They all willingly supported with donations to cheer them on.

-Fix! Fix! Fix! Fix! Fix!

-Edgar Fix is incredible!

Naturally, the bulk of the donations erupted every time Edgar made a significant play.

The Doom Suit, atomic bomb, and Titan had generated astronomical amounts.

[…Incredible. The money recovered now is far greater than the investments made over the past year preparing for this war.]

As a result, this single battle had compensated for and surpassed all losses from the past year.

Additionally, numerous byproducts left behind by various monsters had piled up, and converting those into cash could yield even greater profits.

Edgar smiled as he declared.

[Time to farm. Gather up everything we can. We need a tremendous amount of money to complete ‘Noah’s Ark’ and ‘Doom Buster.’]
