I Became a Genius Mechanic at the Academy

Hell.

This place, filled with poison and magic, was always relatively quiet.

Even though countless demons were trapped here, they were all in a sealed state.

The only demons able to act here were the Lords of Hell seated on the six high thrones and a few demons they had awakened.

All other demons were asleep under the power of the seal, remaining silent like gargoyles turned to stone.

【Kraaak! Kyaaak!!】

【Crululu! Crululu! Koooooo!!】

However, now that the power of the seal was almost lifted, the hunger of the demons was rampaging wildly.

It was as if a hungry beast, starved for a long time, was glaring ferociously; this Hell was expressing its filled hunger with terrifying roars and movements.

Once the seal in Hell was broken, it felt like they would burst forth like a balloon popping when poked with a needle.

【It’s almost time.】

And the Lord of Hell, who had been observing this scene, finally stood up.

As if the weakened power of the seal was instinctively felt by the demons, they also knew the seal would soon be lifted.

Once the seal was lifted, they would be able to move their bound bodies freely and eradicate the despicable humans.

【Izazel, remember. This is war. Not a massacre.】

However, all the Lords of Hell who had twisted their lips to escape here in previous rounds now wore somewhat stiff expressions.

This was because everything they had planned was completely thrown off due to the actions of Edgar Fix.

【I know, Melfirn. I too recognize the seriousness of the situation.】

Thus, the “Ruler of Nightmares,” Izazel, was devoid of any smile on his face.

His true power stemmed from the number of humans corrupted into demon worshipers.

Now that there has been an 80% decrease in demon worshipers compared to before, he was fully aware of the gravity of the situation.

They needed to leave here with the mindset to wage “war” rather than “massacre.”

【The situation has changed a lot… Many humans who should have become our powerful subordinates have hidden within his walls… The filthy humans have united around him… Moreover…】

Izazel trailed off, recalling the time he faced Edgar Fix.

Back when he tried to pierce the northern defense line with the army of Lilith.

At that time, he had cast a mind-destroying spell to test Edgar’s abilities, but was thwarted by a strange technique called “Frequency Blocking,” resulting in a futile failure.

Even though his physical body was sealed here and he couldn’t exert his full strength, the shock of losing so easily was immense.

【His power… has grown to the point of reaching us.】

Above all, the power of the strange armor called the “Doom Suit” was considerable.

It was as if it could tear apart anything that existed with just one person.

The thought that “I might lose” sent chills down the spines of the Grand Dukes.

Now they could no longer afford to watch the situation unfold leisurely as they had before.

【I understand the seriousness of the situation, but there’s no need to panic.】

At that moment, one of the Lords of Hell stood up and said those words.

Baal.

He had never participated in a war until now, but was finally showing his fighting spirit in this world line.

【In this world line, I will also take action. Moreover, Melfirn, you have never intervened directly either. None of us has shown our true strength.】

【…】

【…Rather, I’m excited… Finally, he has shown his card called ‘Edgar Fix.’ I’ve been so bored with meaningless victories following the same pattern every time; this is actually a good thing. I can finally face that despicable fellow properly. Also, now that he has played his last card, sealing him in this world line will end the collapse of this accursed world line. The universe we win will endure forever.】

Melfirn nodded.

The universe confirmed by their victory.

That future was something he had always dreamed of, and at one time, he wanted to achieve it alongside Edgar Fix.

But Hayado had betrayed them and imprisoned them here, desperately trying to stop them.

They had an obligation to exact thorough punishment.

【…The barrier here will soon be lifted. As planned, we aim to draw him out.】

With those words, Melfirn stood up.

Following him, the other Lords of Hell also rose to their feet.

Then, cracks started to spread throughout the barrier surrounding all of Hell.

With a loud bang! it shattered, releasing a massive shockwave.

Melfirn unsheathed his sword and shouted.

【Now it’s our turn.】

“Eve, what’s the damage report?”

Ed rushed into the situation room and asked Eve for the damage situation.

Eve began to explain the situation unfolding globally by displaying various data screens she had prepared in advance.

“First, most of the remaining humanity is succumbing to demon corruption… I don’t think we can save them.”

Ed looked at the screen Eve was pointing at.

Humans being corrupted by the “Ruler of Nightmares, Azazel.”

They were all those who had rejected the hand Edgar had extended, humans who wanted to remain on the land they had lived on, even if it meant dying.

He had tried to persuade them, threatened them, even risked his own life, but in the end, they chose to remain and face death.

-Kwaaaaak…

Ed clenched his fists.

He had known from the beginning that he couldn’t save everyone, but seeing humans succumb so foolishly made him angry.

“It can’t be helped. All I can offer them now is peace.”

Yet, Ed bore no regret.

He had done everything he could do, and it was their choice to reject his hand in the end.

He never entertained the arrogant thought of saving all humanity in the first place and already knew it was impossible.

He was just frustrated to see them actually being recycled into the enemy’s useful force.

“And, the reconnaissance drones are being destroyed. Of the 4075 reconnaissance drones scattered across the world, 40% have already been destroyed and can no longer transmit images.”

However, the destruction of the reconnaissance drones was a bit unexpected.

He had taken measures to prevent damage, yet 40% had already been destroyed.

It was evident that a Lord of Hell, who had never shown himself, was using some unknown power.

Otherwise, such variables wouldn’t occur.

“…Do you think you know the reason? Why so many drones were destroyed in such a short time?”

“I was just about to say that. I analyzed the footage captured before the drones were destroyed.”

Eve said that as she displayed an array of shattered screens.

Each video was the last footage taken by the destroyed drones, about a minute long.

And they all had one common point.

“It seems there was a problem with the flight.”

The drones were captured spinning erratically while filming.

In other words, there was an issue with maintaining stable flight.

“…Yeah. From the sound and image quality, it looks like it was sudden strong winds.”

The drones were destroyed by powerful winds, as if swept away by a typhoon.

Based on this information, Ed could hypothesize one critical point.

The unknown Lord of Hell was capable of moving quickly and might even control the wind.

After all, thousands of drones scattered worldwide were destroyed in an instant by a sudden gust.

“Eve, display the regions in the order the drones were destroyed.”

“Okay.”

Ed began verification to see if his hypothesis was correct.

He would analyze the order in which the drones were destroyed to confirm the enemy’s trajectory.

“Is this guy moving with the wind?”

As a result, Ed could deduce another hypothesis.

After creating a roadmap in the order the drones were destroyed, it aligned closely with the direction of the wind.

“Eve, can you overlay the pressure information and geographical features of each region?”

Ed asked Eve to display the data of each region for more solid verification.

However, Eve revealed that she had not collected pressure information, plunging Ed back into thought.

How could he confirm the wind’s trajectory?

“Ah.”

At that moment, a light bulb went off in Ed’s head.

He figured out a trick to ascertain the wind information for different regions.

“Eve, call in the tactical experts from each affected country.”

And that trick was to summon tactical experts.

Because in medieval warfare, wind was a significant variable, and tactical experts were obliged to understand geographical traits and wind direction.

Thus, Ed brought in tactical experts from each nation and requested the data they had recorded.

As a result, he could identify about 75% of the areas concerning local winds and seasonal winds.

He concluded that his hypothesis was correct.

“This guy is indeed moving with the wind?”

It seemed certain he possessed the ability to travel with the wind.

Considering the speed at which the drones were destroyed, the locations where winds were strong caused the drones to be destroyed faster.

“Overall, it seems they’re moving with the seasonal winds… while in mountainous areas, they rode the mountain valley winds and katabatic winds… and along the coast, they exploited the sea breezes… This terrain utilized the glide winds…”

As Ed traced the roadmap of the destroyed drones, he became increasingly confident in his hypothesis.

This fellow moved by riding the wind and perhaps could manipulate it artificially.

“…Ha. So this was the scheme.”

Eventually, Ed reached the end of the roadmap.

The point where the last drone was destroyed.

That was at the beach leading to the tropical low pressure.

In other words, it was warm waters where typhoons frequently occurred.

He planned to conjure a massive typhoon from the sea to assault behind the barrier.

“I need to go greet him…”

An artificially generated typhoon.

If that typhoon were to grow to an unprecedented scale in history and sweep over this place, they would inevitably suffer immense damage.

Thus, before the typhoon grew by feeding on the moisture, Ed needed to predict where it would generate and punish him early.

He immediately summoned specialists to counter this threat.
