The Game of a Legendary Genius Dark Mage-Chapter 325

3.

Kingdom of Rieskan — Heptarion.

The only city in Rieskan where a Mage Tower stood, and one Seong was familiar with.

A city preserved exactly the same, even in this distant past.

In a game world, that was to be expected—but even so, Seong found it oddly surprising.

So even this place has one of those so-called rat holes leading to the Demon Realm?

I wonder if it got sealed afterward once this whole event ended...

Well, this was a past-replay scenario via the scenario book, after all.

It made sense.

Leaving a path unsealed after a surprise infiltration would just be plain stupid.

In any case, Seong’s team arrived in Heptarion and infiltrated the city.

Once regrouped inside, they let out a quiet breath of relief.

“Thankfully, the security isn’t too tight.”

“Indeed.”

That comment came from Brishia, the elderly Spirit Knight.

The barbarian warrior Stoneheart nodded in agreement.

Naturally, it made sense.

“They never expected us to attack from this direction. Of course it’s lax.”

At Will’s comment, Seong and Babaros nodded as well.

Once their team had fully assembled, they cautiously unfolded the map they received from Black Star.

The light-imbued map displayed the location of the rat hole within the city—and it wasn’t far.

“Let’s head out.”

Brishia, the eldest and de facto team leader, took charge.

No one objected.

No one was here to argue over seniority or posturing.

It was more efficient to let whoever naturally took charge lead.

At Brishia’s words, the five figures vanished in different directions.

There was always a chance they were being tailed or watched.

By scattering and regrouping, they managed to shake off any potential pursuit and reunite not long after.

The place marked near the rat hole—

“A warehouse.”

“A perfect place to hide something.”

“Agreed.”

“No visible guards outside, but...”

“There are people inside.”

Babaros, having used detection magic, concluded with that final observation.

Brishia nodded.

A barrier was masking the energy inside, and there were life signatures guarding it.

They needed to deal with this quickly.

Seong, Will, and Babaros exchanged nods—

Will moved first.

With a simple gesture, his undead stirred and stretched toward the ⊛ Nоvеlιght ⊛ (Read the full story) barrier.

As it slipped through like vapor, the barrier weakened for an instant. Babaros immediately followed with a dispel, partially unraveling it.

They left the containment barrier intact—to prevent demonic energy from bursting out—but dispelled only the barrier that blocked intrusions.

“What the?!”

Brishia was about to scold them for moving without her orders—

But Seong had already slipped inside.

Inside the warehouse, cloaked in darkness, the demonic energy was thick and suffocating.

Two lower-ranked demons jumped at the sight of Seong suddenly appearing.

Even with the barrier in place, he’d broken through.

Startled and ready to react—

But they couldn’t.

Seong’s blade, darker than pitch black, carved through the air like starlight.

Helena’s top-tier sword technique — a blend of her first form, Dance of Darkness and Galaxy — severed all their senses before they could do anything.

Looking over their bodies, Seong muttered:

“They moved their hearts to other places.”

If killed recklessly, the demons might have relayed information elsewhere.

So instead of slaying them, Seong simply shut down their senses and left them.

Brishia and Stoneheart stared in astonishment at the trio who had executed everything flawlessly.

They looked like they’d worked together for years.

Even if Brishia had given the command, she wouldn’t have achieved a cleaner result.

Stoneheart felt the same.

Inside the warehouse, the team used sealing spells to trap the demons.

According to Brishia, the seals would hold for at least several days.

Everyone nodded.

“Let’s explore the area.”

At Brishia’s suggestion, the group searched the warehouse.

They soon felt a pulse of demonic energy from below.

They descended.

And found it.

A ripped-open space spewing vile, disgusting demonic energy—an entrance to the Demon Realm.

A dimensional tear.

Stoneheart and Brishia frowned.

Seong, Babaros, and Will calmly began preparing.

Their composed reaction made the older two click their tongues in disbelief.

“We’ve fought demonkin plenty of times ourselves, but...”

“We can’t match your composure. It’s honestly humbling.”

Their tone was sincere.

Seong, Babaros, and Will exchanged modest smiles.

Their objective was to destroy the Essence as quickly as possible.

There was no time for sentiment.

With that, they stepped through the passage.

A gray sky stretched overhead.

A black moon loomed above.

A world soaked in foul demonic energy spread out before them.

But it wasn’t the demonic energy that hit them first—

It was the aftereffect of dimensional travel. 𝗳𝚛𝚎𝚎𝘄𝕖𝕓𝕟𝕠𝚟𝚎𝕝.𝗰𝕠𝐦

Like a wave of nausea ripping through the soul, vertigo and sickness overwhelmed them.

Everyone staggered—

Except for one.

Seong.

“Gueehhh—! I... I’m gonna die.”

“Gahhh, how... how are you enduring this?”

“Amazing, truly...”

“As expected of Seong...”

As everyone groaned in awe, Seong scratched his head.

So this is some kind of status effect...

A notification told him he was protected by the authority of Overlord.

He scratched his head again, sheepishly.

He hadn’t expected to be immune to something like this.

Oh well.

His teammates were clearly wrecked by the trip.

They decided to rest a short distance from the passageway.

As they sat down—

“Hoo... Seong, you’re incredible. To endure that kind of nausea without flinching...”

“That’s not something you can fake...”

“Exactly.”

“Ugggh, I-I still feel sick...”

Brishia and Will seemed okay.

Surprisingly, Stoneheart and Babaros were still struggling.

Seong glanced at them and scratched his head again.

The Overlord class really is nice...

And it’d give him a serious edge in future interdimensional travel.

Considering that the Overlord embraced the Realm of the Dead itself—

It made sense he’d be fine.

While resting, Brishia began planning again.

“I keep trying to think of a stealthy infiltration approach, but... it's not easy.”

“Yeah...”

Not far in the distance—

They could see the fortress.

They hoped to draft a plan.

But...

“The guards are too tight.”

“Even if we used stealth, this layout makes it easy to get spotted.”

“This is bad.”

“Hmmmm...”

As everyone racked their brains—

Seong remembered the battle in Ninyaru.

The time they used an elite strike team to flank during the war.

But—

“It’s not the same as then...”

They might be able to shake the demonkin defending that place—

But the ones guarding the fortress weren’t pushovers.

Two high-grade demons.

One noble of baron rank.

Maybe if he summoned all his minions, it could work.

But...

“Victory isn’t guaranteed.”

As Seong mulled it over, the others watched him silently.

Until finally, Babaros spoke first.

“Do you have a plan?”

“Huh? Oh...”

Seong thought a little longer, then nodded.

“I think I’ve got a decent idea.”

Everyone turned to him with similar expressions.

Then—

“...C-Can that even work?”

“...Seems impossible.”

“Huhhh...”

“Hmmmm...”

Everyone looked at him like he was out of his mind.

But then—

“I think it’ll work.”

Seong nodded confidently.

The others looked a bit guilty—but they had no choice.

There was no better plan.

Everyone nodded reluctantly.

“At this point, it’s our best option.”

“The hardest path is often the shortest.”

“We trust you.”

“We’ll follow your lead, Seong.”

Their voices rang out with conviction.

And Seong began explaining the detailed plan.

Everyone listened—and nodded.

4.

The fortress holding one of the Essences of demonic energy—

A baron’s domain.

Ordinarily, such a domain wouldn’t be large.

But thanks to the Grand Duke’s blessing, Baron Kalgmir Lucentios now possessed a fortress far larger than before—and he was quite pleased with it.

Of course, he had also been entrusted with the Essence of demonic energy.

At first, he thought it was a bothersome duty.

But it turned out—

“Way better than I expected.”

He assumed someone would come to steal the Essence.

But no one came.

Not even a hint of an enemy.

And it made sense.

“The rat holes are guarded, and even the places where they emerge are under our control. If someone attacks, it’ll just be a handful of them.”

That was the logic.

All other paths were sealed by the Grand Duke.

The only access points were those rat holes—and they could only allow a few people through.

Unless extremely powerful enemies showed up—

And really, how many of those existed in the human realm?

And even if they did, nearby demon lords would come to help.

It wasn’t a big deal.

In fact, it was pretty easy duty.

Kalgmir enjoyed his life.

No extra responsibilities. Just a bigger castle.

But then—

One mid-grade demon came running in, trembling.

“Lord! We’re under sudden attack!”

Sudden attack?

So someone had finally come.

Still, it had to be a small force.

Kalgmir scoffed.

“How many?”

At most five, he thought.

He asked calmly.

The mid-grade demon, trembling, stammered—

“I-It’s hard to say exactly... but the estimate is... ten...”

“Ten?”

Okay, more than expected.

Just as he was about to wave it off—

“T-Ten... thousand, sir.”

“??????”

T-Ten... what?

Kalgmir blinked, confused—

Then loud shouts erupted outside.

“Hold the line!!!”

“They’re coming straight at us!!!”

“Fucking undead bastards!!!”

Kalgmir turned back to the demon.

“It—it really is ten thousand, my lord!”

“...Fuck.”

So much for easy duty.
