I Became a Genius Mechanic at the Academy

---

Before I possessed this body, I had seen similar writings on the internet.

It said that the only country where you can get water and various side dishes for free is Korea.

Furthermore, it claimed that the only places that charge you nothing for smartphone charging are in Korea.

When you go abroad, you have to pay for everything.

I remember seeing that kind of writing.

“Ah… so this is the warmth of my homeland.”

In that sense, this place is filled with warmth.

They’re even charging my Crucible by sacrificing their own life force.

I can feel it.

I can feel the hellish energy rising in real time.

Ever since it was charged in my territory, I had been worried about how to recharge it.

To think I’d have my troubles solved like this.

Those Demon Church folks were actually good guys.

I’m sorry for hating them all this time.

[Charging… 83%]

Feeling grateful, I sneaked a glance at my status window, and it showed that it was charged to 83%.

Well, considering I’ve been lying here for quite a while, it makes sense to have reached this level.

Even if the Crucible is known for consuming hellish energy for a long time.

After all, there are 30,000 believers spread across the kingdom charging it.

“Y-young new humanity…”

At that moment, the bishop called out to me with a face that looked like it had aged several years.

He then wiped the sweat from his forehead and continued.

“Is it still… still not enough?”

“…”

The bishop has already asked me for the third time if it’s still not sufficient.

No wonder, originally the Grand Duke should have already been summoned.

The summoning ritual they are conducting limits the time the Grand Duke’s spirit can remain in the manifestation, so hellish energy charged to about 60% would be sufficient.

“Just a bit more…! Push a little harder…!”

But it won’t do.

It’s still at 83%.

The remaining percentage needed to reach 100% is 17%.

You all need to push just a little more!

You guys can do it!

“B-but… we’ve already exhausted too much of our life force… If we continue with the ritual any longer…”

“…”

I scanned his face.

He looked worn as if he had been through many seasons.

Upon closer inspection, he looked much older than just 30 minutes ago.

That’s how much life force he had used.

“Ooh…! I-I can hear it…! The voice… of him…!!”

So I widened my eyes and took hold of his hand.

He claimed he could hear the voice, and I encouraged him by saying that the Grand Duke was coming this way.

Tears began streaming down his face.

“Ah… he… he is coming…”

“That’s right… he’s coming… What is your name?”

“My name is Jordic…”

“Jordic. He will remember your name. When the holy sword of our salvation is completed, this sword imbued with his spirit will repay all your sacrifices and services.”

I sold them hope.

Hope that they could charge the remaining 17%.

Fortunately, deceiving these fanatics was a piece of cake.

As I promised them rewards while spewing hellish energy from the suit, their enthusiasm reignited.

“Did you hear that! His voice has reached here! He is coming here! He will remember you! He will repay you!”

And just like that, the bishop began encouraging the believers who were on the brink of collapse.

The believers, tasting hope from the bishop’s words, cheered and put their efforts back into completing the spell.

Once again, a massive amount of hellish energy began to fill the Crucible.

[Charging… 100%]

I wondered how much life force I had drained from them.

Finally, the Crucible was fully charged.

What was previously only 6% charged was now filled to the brim.

All thanks to the warm-hearted Demon Church folks.

“Your task has been completed!”

Having finished the charging process, I raised the Crucible high and stood up.

The members of the Demon Church were on the verge of collapsing, but upon seeing the completed Crucible, they began to cheer and cry.

Their efforts were finally rewarded.

“And he has promised! That he will accept you all as the new humanity!”

“N-new humanity…!”

“Yes! Look at this place.”

Saying so, I took out the installation bombs from my inventory.

I was talking about bombs with explosive power equivalent to 15 times that of dynamite, with a force of 15 TNT.

I pointed at the mound of installation bombs and said to them.

“This is the communication device through which you can receive his power.”

““Communication device…!””

“That’s right. Form groups of 8 and sit around the communication device in the center. Then his holy power will flow out from the device and envelop you.”

The believers gazed at the installation bombs with ecstatic faces.

The bombs I made looked just like the kind of treasures that demons would use, making it easy to deceive them.

Originally, I designed them to be difficult to remove, but I never imagined I’d be able to use them like this.

“Thank you…!”

In any case, they started taking the installation bombs while expressing gratitude towards me.

They were so well-trained that even without anyone to control them, they easily formed groups and sat around the bombs.

I waved them goodbye one last time.

“Then I will go end this war! You all too, once you receive his power and evolve into the new humanity, join me in this holy quest!”

““Yes!!!””

“Then.”

After saying my farewells, I patted the bishop’s shoulder and thanked him for his hard work.

Then, I confidently exited the cathedral towards the main gate and put some distance between myself and it.

Once I felt I was far enough away from where they were in the cathedral—

-Beep.

-KABOOM─!

I pressed the remote ignition switch.

With a tremendous bang, the cathedral shattered into pieces.

I had granted the hard-working members of the Demon Church a sweet sleep.

Having exploded while in human form, they wouldn’t have felt any pain and would have gone comfortably.

“Well then, shall we go?”

However, I still had work to do.

I needed to kill Gyro, who turned the Entica Kingdom into a demon den.

Coincidentally, I heard news that the Imperial Army was in chaos.

The Entica Kingdom forces, tainted by the Demon Church, were undergoing monster transformation, causing the situation to turn dire.

It’s said that Elena was having a tough time dealing with the demonized Gyro.

While she is indeed the strongest among humanity, Gyro was once a Sword Master, and having become a demon based on that power, he was a formidable opponent.

“It’s a pity, but I won’t get to test the Doom Suit.”

So I decided to end the war rather than test the Doom Suit.

For the sake of saving even one more person from the imminent invasion of demons in the future.

I spread the wings of the demon suit wide and soared into the air.

***

“Ugh…!”

A groan escaped Elena’s lips.

Unknowingly, she let out a groan in the face of an enemy far more powerful than she expected.

Elena was startled to experience a strength she had never encountered before.

“Is this why Edgar was so wary of demons…?”

The Great Mage Elena.

In fact, everything in this world came too easy to her.

In a world where spells and mana were everything, she was born with a talent that would not allow anyone to follow.

Thus, even the spells that others would struggle with for days were mere child’s play to her, taking only 1 or 2 minutes to solve.

For example, one day a professor at the magic academy introduced the ‘Three Major Spell Challenges’ by writing it in the corner of the blackboard, but Elena solved it all in just one day and turned in her answers with the words “I did my homework.”

She mistook what was intended to show that such challenges existed for a homework assignment.

And upon verification, all her answers were correct, confirmed by several professors.

Thus, an unprecedented and unparalleled genius was born.

【Great Mage Elena. You’ve been the most troublesome enemy in all the previous lives. I must kill you here.】

Yet, even she found herself struggling.

For any attack she attempted against the demonized Gyro passed right through.

His skin felt as if it were made of the hardest substance in the world.

No pressure from psychic force, freezing, flames, or lightning had any effect on him.

【Die!】

At that moment, he swung his arm at incredible speed.

The sound of a sharp slicing tore through the air as a deadly aura erupted from the tips of his claws, aiming for Elena.

-Hwoosh!

But Elena was a master of teleportation.

She dodged Gyro’s attack using near-range teleportation.

Gyro immediately kicked off the ground and charged toward Elena, but she teleported again to evade his strike.

【You little rat…】

Thus, neither could deal a blow to the other.

Elena evaded all of Gyro’s attacks, while Gyro easily withstood all of Elena’s.

It had become a war of attrition; Gyro using health and magic, and Elena using mana.

【Cardinal Gyro!!】

At that moment, with a thunderous shout, a colossal figure landed on the ground.

Turning to face the sound, an enormous demon emanating massive magic power stood up from the dust.

The demon approached Gyro and spoke.

【I’m late. I am Marquis Kargos. I have come here at the behest of our Lord to support you. I’m also of Cardinal rank like you.】

【…】

Marquis Kargos.

Gyro raised an eyebrow.

He certainly remembered that name.

When the Grand Duke had shown him visions of previous lives, Kargos was always a commander-level figure who served at the side of the Lord, leading the army of hell.

【…It’s too early for you to have risen to the rank of cardinal. I thought it would happen around the time the Eastern Kingdom fell.】

Yet it was strange; it was far too soon.

Unlike himself, the first cardinal, others did not appear until quite later.

To have already risen to cardinal at this stage was unexpected.

Kargos replied.

【That’s indeed the case. I would have appeared at least a year later.】

【…】

【However, there are many variables this time around. The biggest variable is the very existence of ‘that guy.’ Because of him, I have received the Lord’s call earlier than expected.】

As Kargos said this, he clenched his fist.

Torrents of hellish energy were released all around.

‘…Indeed, he is a demon.’

Gyro nodded at that.

There was no way someone could reproduce this amount of hellish energy so easily.

Only someone who had committed every possible sin as a human and had received the Lord’s selection would be able to bear this much.

【But let’s set introductions aside. First, we should tear her apart.】

At that, Kargos extended his hand into the air.

Suddenly, a crack appeared in the space, and a sword materialized in his grasp.

A magic sword infused with such immense hellish energy that it nearly befuddled the mind.

【…That sword?】

【This is the sword granted by the Lord. It’s also the sword that will end this war.】

…A magic sword capable of ending this war.

A smile broke across Gyro’s face.

The Lord has gifted him such an extraordinary sword for his own sake.

Kargos then spoke.

【You take the initiative. I will be right behind you to strike off her head.】

Your opening move combined with Kargos’ follow-up strike.

Gyro nodded.

Seeing Elena’s flustered expression, he curled his lips into a grin.

No matter how great the Great Mage Elena is, she wouldn’t stand a chance against a double assault by two Cardinals!

Just as he was about to charge in—

-Thunk!

【…?】

A warm sensation unexpectedly spread across his back.

A sharp magic sword made of hellish energy protruded from his chest.

Turning around, he saw Kargos with a twisted smile.

【…W-what is the meaning of this…?】

-Slice!

Before he could solve the mystery, the Crucible pierced through his chest in an instant.

His vision spun chaotically before crashing to the ground.

His head was severed.

【Well done.】

Edgar gave a thumbs up as he looked at Gyro’s fallen head.
