I Became a Genius Mechanic at the Academy

---

Thousands of years ago.

So, during the Genesis when Heavenly Beings and the Lord of Hell waged a great war.

At that time, the Orcs stood alongside the Lord of Hell.

As the Heavenly Beings drew the human world to their side, the Lord of Hell absorbed the Orcs, a sentient race, into his ranks.

As a result, humans began to wield the “magic” passed down by the Heavenly Beings, while the Orcs utilized “demonic magic,” a fusion of the demon’s sorcery and their own unique spells.

And that brutal and cursed magic was passed down to the Frost Orc tribe over thousands of years.

-Whoosh!!!

Thus, the Frost Orc shaman ambushed the imperial soldiers using demonic magic.

They cast a large-scale curse on the imperial army summoned near the siege weapons, drastically reducing their speed and power.

-Wh-what is this…?!

And this type of magic was something the humans of the present age had never experienced before.

The time when Orcs and humans were engaged in a large-scale war was during the Genesis when Heavenly Beings really existed.

The imperial soldiers found themselves flustered by this “curse magic,” which was unlike anything they had encountered before.

-Huff! Huff! Huff!

However, their brief confusion would leave them with a fatal wound.

Frost Orc assassins lying in ambush rushed at the teleportation mage all at once, taking his life.

-Damn it! Break the debuff with Dispel! This is like a debuff magic!

Finally coming to his senses, the imperial commander analyzed the nature of the curse and ordered it to be dispelled.

But by the time the curse was lifted, the teleportation mage was already dead.

The only escape route had been blocked.

[Rip their flesh and drink their blood!]
[Whoosh!]

Thus, having lost the teleportation mage, the imperial army found themselves isolated.

Countless Orcs began to surround them.

Various spells and piercing weapons rained down upon the imperial soldiers.

“Calmly deploy defensive formations! We’ll break through the encirclement and return to the walls!”

Then, the squad leaders quickly issued orders to quell the chaos within their ranks.

The command to break through the encirclement and return to the walls.

However, the difficulty of carrying out that order was extremely high.

It was nearly impossible to escape several million troops encircling them to the walls a few kilometers away.

‘These guys are of a different breed! They’re not the Orcs we knew!’

Moreover, the Frost Orcs were unlike ordinary Orcs.

Enhanced into demon types.

Their power and wickedness were incomparable to that of normal Orcs.

Additionally, the Frost Orcs weren’t just degraded monsters; they were “sentient beings” that had inherited their unique culture and knowledge.

Thus, they turned the imperial army’s operations against them, isolating them.

“We must rescue our allies immediately!”

Meanwhile, in the command room, opinions were split in two.

One side believed more ground forces should be dispatched to rescue their allies, while the other believed sacrifices must be made to minimize damage.

Both sides had valid points, and thus the disagreement was slow to resolve.

In the midst of this, Duke Ireya burst through the door of the command room.

“What do you mean, sacrifice?! Stop with that nonsense! Even without your permission, I will mobilize all my troops under the name of my Cruel to rescue my daughter, so you all just shut up and open the door!”

The Alpha unit, isolated due to the enemy’s ambush.

And Enya and Isabella were in the Alpha unit.

Thus, Duke Ireya was desperate to retrieve Enya.

“I agree with Duke Cruel. I will join the rescue operation using all forces of Graham, so open the doors immediately.”

Following this, Duke Graham backed Duke Cruel’s opinion.

Having abandoned his daughter in suffering for the sake of “family duty,” he couldn’t afford to lose Isabella like this.

“I will also join. It is entirely my responsibility for sending my student into battle.”

Notably, Elena, who had recently recovered her strength, also sided with the “rescue” faction.

Thus, the top command office established a rescue operation and gathered ground forces.

Mercenaries, private troops, imperial soldiers, allied forces, and anyone else who could be gathered in numbers as large as possible.

-Crunch…

And so the main gate of the walls opened.

Frost Orc chief Kral sneered menacingly as he mumbled.

[They’re walking right into their grave. How foolish. Sweep them all away!]

The wall, which couldn’t be easily breached even by the “decay bullets” gifted by Lilith.

Yet the humans stepped out on their own, leaving the wall behind.

For chief Kral of the Frost Orcs, there could be no better news.

[Warriors, go greet them! Show them the fury we’ve endured for hundreds of years!]
[Whoosh!]

Thus, a large-scale Orc force began to charge.

The two giant factions rushed towards each other.

-Clash!

And the imperial alliance discovered the moment they clashed with the Orcs.

These were indeed not the usual Orcs.

They were also “magic users” who fought employing mana.

-Clash! Clash! Vrooom!

-Dieeeee!

-Whoosh!

Thus, the battle spiraled into chaos.

Both races had magic users skilled at manipulating mana, making it difficult for either side to gain the upper hand.

“Don’t obstruct the path of Cruel!”

However, among the magic users, some distinguished themselves by honing their skills to the utmost.

One such was Duke Ireya Cruel, who was stirring up the battlefield.

Having reached the peak of Sword Mastery, he had the strength to fell dozens of foes with a single strike.

The Frost Orcs facing him fell like autumn leaves.

[That human is rather formidable. But we have warriors just as good as him too.]

Still, chief Kral of the Frost Orcs remained unfazed.

He calmly summoned his subordinates and prepared the “High Warriors.”

The “High Warriors” of the Frost Orc tribe were those who had reached the peak of martial prowess, honored by Orc warriors.

They possessed strength and abilities comparable to Sword Masters.

[High Warriors, finally, a worthy opponent has appeared. Go and behead him, showing the humans who the strongest warrior truly is.]
[Whoosh!]

And so, eleven High Warriors joined the battlefield.

They each charged towards key figures of the empire, such as Ireya, Gracia, and Adrian, issuing challenges.

“····! Damn! Such powerful Orcs…!”

However, that wasn’t the scenario the imperial army wished for.

Their goal was to carve a quick path and rescue their isolated allies.

Engaging in prolonged skirmishes with the enemy left them no time to spare.

Moreover, with the opposing forces outnumbering them by several times, the longer they dragged things out, the more disadvantageous it became.

“Duke Cruel! Duke Graham! We must retreat! At this rate, we’ll be surrounded as well!”

Thus, the battle was turning unfavorable.

Despite expecting to effortlessly carve a path to rescue their allies with the strongest army of three Sword Masters and a Great Mage.

The Orcs also had formidable warriors, leading to unpredictable variables.

“We’re not throwing in the towel yet! I’ll hold them off, so clear the way!”

But giving up was not an option.

Especially since Elena, who had allowed her students to join the fray, felt a heavy sense of responsibility.

“Come on!”

Thus, Elena urged to execute the operation even if it meant straining herself.

Having exhausted a lot of energy defeating three High Warriors, she stepped forward, indicating she would take on the remaining ones.

[You took down three great High Warriors, and for that, I commend your spirit.]

But at that moment.

The Frost Orc High Warlock “Gazsha” stepped forward.

And the moment Elena laid eyes on Gazsha, she immediately understood she was a formidable foe.

With her azure eyes surveying, the Orc woman was exuding an energy at least comparable to Duke Ireya or beyond.

“······.”

Thus, Elena and the staff involved in this rescue operation inwardly realized rescuing their allies was practically impossible.

They had assumed the Orcs were just common monsters.

Yet here they were, equipped with skills and abilities rivaling humans.

Now was the time to seriously consider retreating to save whatever remaining troops they had.

“Look, over there!”

But just then.

Someone shouted urgently while pointing at a specific spot.

There, a lone figure was walking toward them.

Edgar Fix.

He had been lying low to prepare something to end this war, and now he finally revealed himself.

-Could that suit be… the secret to ending this war?

-It’s just, an ordinary suit like any other…

However, what Edgar had prepared was far too mundane to be a secret for ending the war.

From its appearance, it seemed no more special than a Doom Suit.

Moreover, what he held in his hands was also a weapon that could be found lying around.

A double-barreled shotgun such as that was just an ordinary firearm even a dwarf could develop.

“What… what is that power…?”

But those like Elena with “azure eyes” could recognize it at a glance.

How formidable Edgar’s strength was when wearing the Doom Suit.

They comprehended why he had hidden until now, sacrificing himself to finally show up.

Truly, Edgar, wearing the Doom Suit, was a being who could be called the strongest with the “power to end a war”…

***

Power surged through my entire body.

It felt as if I could smash this world to bits with just a clenched fist.

I felt as if I could truly manifest the universe marine who was sealed away after wandering hell eternally, defeating demons.

Indeed, unlimited power surged within me.

“······.”

Yet suddenly, the process of how I came to acquire this power flashed through my mind.

Gaining the ability to smash any demon was overwhelming.

Perhaps that was because the path to achieving this power wasn’t easy.

It was truly a power won through bone-crushing effort.

‘I was just lucky.’

Moreover, many fortuitous events accompanied my luck.

For this power to be fully realized, the breaking of the Sigmund family’s holy sword “Black Jade” had to occur.

Because the Black Jade is a cursed sword that converts feelings of hatred and resentment into energy and power, and my “Doom Suit” operated on a similar principle.

Converting my hatred and resentment towards demons into energy was the core power of the Doom Suit.

‘Contacting the World Tree also played a role.’

However, had I only converted my personal resentment and hatred into energy, its power would have been quite lacking.

No matter how intense one’s personal feelings may be, they ultimately belong to one individual.

And the energy emitted from one person’s emotions has clear limits.

-But what if I could draw upon all the emotions of the past rounds…?

Thus, I thought of utilizing “myself” from previous rounds.

No, more specifically, I’d be using the distinct individuals that I perceive as “me.”

After all, even if I’d experienced hundreds of rounds, each experience and emotion was not the same; hence, I had lived each round as a different person.

Moreover, as I perceived past rounds as a game, I had always lived believing only in the current round as the truth.

In certain rounds, I truly loved Enya while harboring hatred for Isabella.

While in other rounds, I loved Isabella, ignoring Enya’s fall.

Beyond that, there were rounds where I was connected with Elena and others where I boldly approached the princess only to face rejection.

There were also rounds where I nearly ended up with Claire, only to drift apart due to minor circumstances.

Furthermore, even if I fell in love in the same way as in past rounds, how could the methods or experiences be the same every time?

Even the smallest incident or coincidence triggered the butterfly effect, leading to different experiences and emotions, granting me different lives.

Thus, the sum of consecutive coincidences molded a “different me” in each round.

For this reason, I do not equate the “me” who fathered Lucas with Adela with “Edgar Fix.”

The emotions I felt in that round belong solely to “him,” while the emotions and experiences of living as Edgar Fix are uniquely mine.

We are simply bound by the sense of duty to “protect the world from demons,” prioritizing it above all else.

There is no intersection between Edgar Fix and mercenary Jack.

‘…If I split my soul into several pieces.’

Thus, I pondered.

Could I not utilize the different versions of myself from countless rounds?

How much power could I gain from an explosion of emotional energy?

‘The World Tree.’

And I could gather that clue from the World Tree.

A wondrous tree storing countless souls.

And “Orbs” capable of controlling those countless souls.

My goal was to study both to create a vessel that could hold all my past rounds.

‘If this is possible, I would become unmatched among demons.’

Thus, for nearly a year, I dedicated my time and effort to the research.

Of course, isolating memories and emotions from previous rounds and storing them in some substance is nearly impossible, necessitating numerous trials and errors.

‘The answer lay in ancient sorcery.’

However, I eventually solved that problem.

In the ancient sorcery Elena was researching, there existed a spell to contain souls.

So, I began creating the Doom Suit, encompassing metaphysics, ancient sorcery, mage-tech, dynamics, and natural science.

I poured in all my knowledge and experience gained from living as “Edgar Fix” to craft the ultimate suit.

‘…It’s complete.’

Thus, I succeeded in constructing the Doom Suit.

I had succeeded in aggregating the emotions of all the past rounds and converting them into energy.

“····Huh.”

And now, arriving at the present.

I feel the explosive surge of emotions from all the past rounds rising within me.

The more demons that exist and the stronger they are, the more energy I can convert those emotions into strength gathered within me.

[I’ve never felt a warrior with such powerful energy! I desire a duel!]

However, at that moment.

A High Warrior blocked my path.

At first glance, he seemed to be at the entry level of a Sword Master.

-Splat!

Yet this guy had chosen the wrong race.

The Frost Orc tribe, now affiliated with Lilith, were of the demon kind.

‘A demon-limited munchkin’ means he was no match for me.

With a single punch, I obliterated his face.

[······!!!]

The faces of the Orcs turned to shock.
