I Became a Genius Mechanic at the Academy

---

The time of regression that Edgar has gone through.

That number has reached an astonishing 978 times.

When converted to years, that’s the year 6846.

In terms of days, it amounts to 2,498,790 days.

In terms of hours, it’s a staggering 59,970,960 hours.

And the Lord of Hell has always enjoyed this long time as a game.

Edgar Fix, or Ha Do-yoon, found them not to be worthy opponents.

[The guy is coming.]

However, what Ha Do-yoon had thought was an easy victory, merely a toy, turned out differently this time as he became Edgar Fix.

And now that Edgar Fix has arisen, he has already killed two Grand Dukes of Hell.

The ancient nightmare of the North, Lilith, and the very storm of death, Baal.

Because of this, the Grand Dukes decided to use all their power.

They resolved to use somewhat petty tricks to lure Edgar Fix outside the barrier and eliminate him.

Since the water supply was contaminated, Edgar Fix had no choice but to come out.

Vrooooom!

In the distance, Edgar’s silhouette could be seen.

However, as the black dot of Edgar’s “Doom Buster” got closer, the expressions of the Grand Dukes hardened.

Currently, the Doom Buster that Edgar was piloting was a massive armored figure stretching an impressive 87m.

[It’s become a monster.]

[Just melt it down.]

At that moment, the Flame of Terror, Karaan, stepped forward.

Wielding the power of flames, he was engulfed in the flames of hell, capable of unleashing a breath several dozen meters long.

Even dragons appeared as mere lizards compared to the breath he could unleash.

– Fwooooooosh!!

Thus, a gigantic breath shot toward the incoming Doom Buster.

And with that alone, the ground ignited, nearby forests were enveloped in flames in an instant.

The air became so heated that it felt like the colors were melting in hot mirages.

“How cute.”

But Edgar knew the abilities of the Grand Dukes all too well.

The Flame of Terror, Karaan, had burned the entire Academy dozens of times.

There was no way he wouldn’t be prepared for that hellfire.

[Automatic fire suppression system, activated.]

Thus, the P.A. Field surrounding the Doom Buster was deployed.

This defensive barrier, known as the P.A. Field, negated energy-based attacks by canceling them out through energy collapse.

It was a powerful cheat-like shield that neutralized all attacks originating from “heat.”

In other words, as long as Edgar’s power source was intact, no attack fueled by “thermal energy” could land.

However, Edgar’s power source came from 978 regressions.

Equivalent to 6846 years.

In days, that meant 2,498,790 days.

In terms of hours, that’s 59,970,960 hours worth of all mental activity energy.

Arguably, his power could be considered infinite.

[I am prepared for death.]

Thus, the leader of the Grand Dukes, Melfirn, made a resolution.

Even if it meant betting his life, they must stop Edgar Fix.

As the four Grand Dukes of Hell prepared for their final battle.

Edgar charged through the breath toward them.

Kwaaaaam!!

A massive roar rang out as the Doom Buster’s fist smashed into one of the Grand Dukes.

It was Melfirn, the leader of the Grand Dukes.

[… …]

However, even after being hit by the fist of the Doom Buster, which contained tremendous kinetic energy, Melfirn stared unwaveringly at it.

He had managed to block Edgar’s attack using a shield that formed on his left arm.

“Not bad.”

But Edgar remained unfazed.

He already knew well the abilities of Melfirn, the leader of the Grand Dukes.

Melfirn’s other title was “Knight King.”

He was the god of all sword masters, a master of weapons, and the embodiment of melee arms.

His arms could transform seamlessly into shields or weapons, with power and defense thousands of times greater than that of a human.

That was why he could withstand the punch of the Doom Buster without a scratch.

“But what about that?”

At that moment, a device sprang from the Doom Buster’s fist, starting to vibrate violently.

Immediately, Melfirn’s shield shattered, exposing his right arm.

Kwaaaam!!

Edgar’s Doom Buster punched deep into Melfirn, sending his body flying far away with a gigantic shockwave.

The other Grand Dukes looked at Edgar with tense expressions.

Edgar grinned.

“Wow~ I feel like this is the first time I’ve seen such expressions on you guys. I died 978 times just to see those faces.”

[… …]

[… …]

[… …]

“Shall we get started? I’ve been holding back for far too long, so I’ve got a lot built up.”

A staggering 978 deaths.

Not just any death, but a “death given everything I had.”

Doing everything he could to protect a world rushing toward destruction and to protect his loved ones, Edgar had always done his utmost.

And in the midst of his despair, there was always the body of his loved ones in his arms.

Edgar had accumulated a lot during this time.

“You were the most evil among them!”

Edgar lunged at the Lord of Hell, Izazel.

He was the Grand Duke of Hell who contaminates humans into demons based on a powerful mind control.

He could be considered the foundation of the “Demon Church.”

All mechanisms by which humans fall into demons derived from him.

“Do you even know how many humans have fallen to become monsters because of you?!”

– Bang! Bang! Bang! Bang! Bang! Bang!

Edgar grabbed Izazel and mercilessly pounded him.

Thanks to his tricks, the number of humans who had fallen into demons was in the tens of millions, and among them were Edgar’s loved ones.

There had been several regressions where Enya or Isabella had fallen into his seduction.

[Kugh!]

But Izazel was not one to just take it passively.

He was the core of mental-type attacks.

All curses and illusions originated from him.

Thus, he unleashed hellish illusions filled with curses, millennia-long curses, and various mental pollution spells all at once.

Thick magical energy surged forth, engulfing Edgar’s Doom Buster.

“That bastard is spamming again.”

But Edgar blocked all of Izazel’s mental attacks.

Eventually, Izazel’s mental attack sent malicious information to destabilize the opponent’s brainwaves.

As long as one could catch and filter a specific frequency, it wouldn’t work.

[What?]

However, it’s almost impossible to detect and block a specific brainwave.

From Izazel’s perspective, this was utterly baffling.

Only Edgar, with the extreme advancement of technology in this world, could provide such unfathomable defense.

“How many humans have turned dark because of all those negative comments you’ve posted?”

[W-What do you mean… ]

“I’m not going easy on you, you bastard. I’ll capture you with my own hands and burn you. Just shut up.”

Bang! Bang! Bang! Bang! Bang!

The merciless punches of the Doom Buster continued.

The Lord of Hell Izazel began to scream in terror for the first time in his life.

Flame-kiri-kiri-kiri-kiri!

At that moment, the Flame of Terror Karaan shot hellfire.

But it all nullified and vanished in the P.A. Field.

Even though it’s hellfire that could burn this world, Karaan was left dumbfounded.

Kwaaaaam!

Then, a gigantic beast’s fist struck Edgar.

Nergal, who could take on any form, transformed into the shape of Behemoth and smashed into Edgar.

The Doom Buster, which had been flying several meters, regained its posture and landed on the ground.

Glaring at Nergal, Edgar spoke.

“Too late, huh? Is that the best form you can muster after all that effort?”

[This form is just the beginning. I am the very adversary to humanity. The monster that destroys the human world is me, the embodiment of every scripture and myth.]

“Oh~ but these days, using mythical monsters is all the rage. Just spending 55,000 won for a package deal makes you capable of soloing in a game.”

Edgar said this while reaching behind his back.

As the back armor opened up, a massive sword handle emerged.

As Edgar gripped the hilt, a colossal lightsaber shot forth.

This beam was also an energy mass of high heat based on Edgar’s emotional energy.

“Go ahead and transform however you like. I’ll chop it all down.”

Edgar aimed the sword at Nergal.

Thus, amidst the standoff between the gigantic monster and the massive armored figure.

Swoosh!

From somewhere, a giant spear flew toward them at high speed.

The automatic defense system of the Doom Buster activated, generating a shield.

However, the massive spear pierced through the shield and struck the armor of the Doom Buster.

Kugugugugung!

The Doom Buster was pushed back and knelt down.

Melfirn, who threw the spear, approached and said.

[Nothing changes. You will lose again this time as well.]

Melfirn stood next to Nergal.

Behind them, Izazel was recovering consciousness and getting to his feet.

Izazel also stood beside them.

As Edgar rose, he declared.

“Gang-ups are one of the officially recognized strategies used by righteous heroes, you know?”

[… …]

“Then I’ll take on the role of the villain. Let’s see what it feels like to get wrecked, huh?”

The corners of Edgar’s mouth twisted into an evil grin.
