Hello, is this a letter addressed to Demon Fortress?

Just moments before the airship was about to plunge into the mist.

Several crystal bottles filled with dark golden liquid were tossed by Morpheus to Lin Gui and Eve.

Lin Gui caught it and was somewhat surprised.

"An 'Ironclad Elixir' to Combat Mental Pollution?"

"The kind that circulates in Bounty City."

Morpheus nodded.

"It was provided by us."

"However, what we sold them was a diluted, inferior version, which was much less effective."

Lin Gui held the cold medicine bottle, even more puzzled.

"You...provided them with the potion to get inside the walls?"

Why?

Morpheus answered very simply:

"To make money."

"Avalon does not actually use currency for transactions."

"But we are too small and have limited resources."

"Many necessities, such as high-grade pharmaceutical ingredients, rare crop seeds, and special metals, have to be purchased from outside."

"Previously, these purchases were mainly handled by Hannah and Roger."

"But they..."

His voice deepened.

"They've been out of contact for over a month."

Lin Gui handed the medicine bottle to Eve and casually said:

"I saw them in Blackwater before I entered Avalon."

"What?!"

Before the words were even finished, the atmosphere on the airship suddenly changed.

Morpheus leaned forward, repeatedly asking:

"Where are they? How are they?"

Kilian and Ruger, who were tied to either side, immediately cast eager glances their way.

Lin Gui did not hide anything and briefly recounted his encounter outside the Blackwater Church.

Rogue and Hannah track down the Witcher Cass, hoping to find clues about Gushin.

After listening, the group of people who had been excited just moments before fell silent.

"Cas... it really is that Witcher Cas."

Ash's voice came from the side, tinged with coldness.

"Sigh," Luger sighed, "I never expected that he would still catch up with Lord Guxin."

"I remember Lord Guxin secretly saving him countless times in the past... Could this departure be...?"

"No," Morpheus shook his head, interrupting him, "Lord Gushin's departure this time was not for Cass."

"He did this to deal with the Alliance..."

"Ahem!"

Killian coughed violently, interrupting Morpheus.

Morpheus realized he had spoken out of turn and immediately shut his mouth.

But the word "alliance" had already clearly reached Lin Gui's ears.

alliance?

Lin Gui's heart skipped a beat, and he immediately thought of the proposal that was to be voted on at the end of the year.

A proposal to formally classify half-demons as an "evil race" and carry out a complete purge.

His mind raced with thoughts.

Could it be that... the Alliance is planning an expedition against Avalon in order to expel or even eliminate the half-demons?

But that doesn't make sense.

The distance is too far to mention.

The sheer horror of the Wall of Sighs and the Corridor of Wailing is enough to bury any army.

Even if the alliance's strongest "Black Dragon Legion" were to arrive, they would likely be completely annihilated.

In terms of the number of titled experts, the Black Dragon Legion slightly surpasses the Howling Corridor.

But these are all spirit demons, truly invincible demons.

Within the alliance, research on the soul has stopped at the level of transcendental soul magic.

It can truly attack those unseen demons.

Besides seizing the moment it reveals itself to attack.

Only soul magic can work.

As for extraordinary-rank magic, it is only for epic-level spirit demons.

Even scratching an itch is considered too much for me.

As he pondered, Lin Gui's gaze remained fixed on the mist ahead.

A gray light flickered in his eyes, and the [Eyes of the Underworld] quietly activated.

The field of vision suddenly changed.

As the gray-white mist dissipated, countless twisted and writhing orbs of soul light emerged.

They come in various shapes and sizes, emanating a chilling, eerie aura.

Several particularly large, dark red silhouettes, resembling small mountains, moved slowly in the distance.

That was the soul projection of the epic demon.

They seemed to have noticed this penetrating "gaze".

Some of the silhouettes paused slightly.

His gaze swept across this direction almost imperceptibly.

Thank goodness.

Perhaps it was because the chase a few days ago hadn't really angered them.

Perhaps it was because the "flavor" of Lin Gui's soul was too "weak".

These terrifying "gazes" did not linger.

It was moved away quickly.

But the trouble was not over.

The legendary figures attached to the flying boat were now within the vision of the Eye of the Netherworld.

Like three blazing campfires!

Against the backdrop of a gloomy, lifeless soul, it shines dazzlingly.

For spirits and demons, this is an irresistible "deliciousness".

Several legendary high-ranking spirit demons that were relatively close began to stir.

Their invisible bodies coalesce and surge in the fog.

Revealing its ferocious outline, it slowly "drifted" towards the airship.

And deeper still.

That familiar area, entwined with countless scarlet, thorn-like soul threads—the territory of Bloodthorn.

At this moment, it began to contract inward.

Bloodthorn, the Epic-rank "gatekeeper," seems to have sensed this subtle shift in the situation.

It... took the initiative to retreat.

It is powerful enough to destroy the Carter capital single-handedly.

However, compared to the true "apex" figures deep within the corridor, it appears weak and powerless.

Meanwhile, those top figures also began to watch the movements of Lin Gui's small boat.

Or perhaps it's because of Lin Gui's eyes.

Or perhaps, three legends are strapped to the airship.

The energy fluctuations it emitted attracted their attention.

In short, those people saw him and became very interested in him.

It began to move its enormous, ethereal body, drifting towards the forest ghost.

Bloodthorn sensed their intentions, so it chose to give way.

They quietly ceded their territory.

Lin Gui didn't move.

The airship hovered at the edge of the mist, eerily quiet.

This unusual stalemate aroused suspicion in Morpheus and the others.

Morpheus assumed that Lin Gui didn't recognize the route marked on the Demon King's Pillar.

Just as he was about to speak up and offer a reminder.

"Shhh."

Lin Gui raised a finger, his voice extremely low.

"Quiet."

Hold on tight to the handrail.

Upon hearing this, Eve tightened her grip on his arm even more.

Lin Gui closed his eyes slightly, took a deep breath, and muttered to himself:

"Wait a moment..."

"I will use a speed that surpasses the limits of an epic-level assassin to rush straight through."

"Do not resist, do not move."

"If you don't want to die..."

He suddenly opened his eyes, his pupils gleaming with a strong gray light.

"Get it on target!"

"Let us pass through the Corridor of Wailing!!"

Before he could finish speaking...

His right hand slammed heavily onto a bright red rune on the control panel.

【Air Pressure Cannon - Start】

"Buzz————————!!!!"

Luger and the others, who were strapped to the outside of the airship, didn't even have time to exclaim in surprise.

The sound was instantly drowned out by the sound of the wind pressure cannon starting up!

An unimaginable, violent thrust suddenly erupted from the tail of the airship!

That wasn't a sound.

That was a terrifying shockwave formed by the extreme compression and instantaneous explosion of air!

A piercing shriek tore through the silence of the mist.

The space in front of the airship seemed to be distorted.

next moment.

The entire airship, along with everyone strapped to it.

It transformed into an out-of-control flying sword.

With an almost overbearing attitude.

It crashed straight into the thick, gray-white fog of the howling corridor!
