Hello, is this a letter addressed to Demon Fortress?

The moment you step into the wall of fog, all sounds around you vanish.

Even the sound of the wind was completely shut out, leaving only a depressing, deathly silence.

Beneath my feet lay soft, damp soil, mixed with the somber smell of decaying leaves.

Just a few minutes.

Eve, having inhaled a little mist, spoke first, her voice somewhat unsteady:

My vision... is a little blurry.

Lin Gui turned his head to look at her:

"Can you hold on?"

Eve gently shook her head and chuckled softly:

"fine."

"It seems that the mist, just as Blackbeard said, can disturb the mind."

Curious, she reached out her hand, her fingertips probing the gray-white expanse before her.

The mist feels cool and moist on the skin, but dissipates immediately upon contact.

At that moment, Lin Gui raised his hand.

[Wind-Drawing Technique] is activated quietly.

The airflow swirled silently, drawing wisps of the surrounding mist to the tip of his nose.

Eve looked at him, puzzled.

Why did Lin Gui deliberately approach the fog?

She remembered clearly that glimpse before she went in—

The other person did not appear to have drunk the medicine.

They were exposed to the fog without any protection.

But at this moment, Lin Gui's expression remained normal, and his eyes were clear and bright.

...Could it be that he secretly drank it without my noticing?

While Eve was pondering, Lin Gui had already quickened his pace.

With his other hand, he made a sweeping motion in the air, and the wind flowed and swirled around him.

The fog surrounding him grew thicker and thicker, churning and surging.

It almost completely swallowed up his figure.

even so.

Lin Gui's mind remained exceptionally clear, and his thinking remained sharp.

Not only was it not eroded, but...

Because of the thick fog, he felt more focused.

My whole body felt light and my mind was exceptionally clear.

Just as Lin Gui was slightly relieved that the awakening spell was working—

Sudden.

Sighs echoed around them.

The voice was hoarse and drawn-out, like the last breath squeezed out of a decaying chest.

It drilled into my ear, sending shivers down my spine and making me feel a chill.

Lin Gui immediately waved his hand to dispel the thick fog around him.

He gripped Eve's hand tightly and pulled her behind him to protect her.

A gray, eerie light suddenly flickered in his eyes.

【Eye of the Netherworld】operates at full power, piercing through the gray and white.

The Wall of Sighs gets its name from the eerie sounds that are ever-present.

As the sound drew closer, according to Blackbeard—

This means that unseen spirits and demons are approaching.

The oak staff behind him floated to his front.

Lin Gui led Eve to sit sideways on the platform, hovering a few inches off the ground.

He stared intently in the direction from which the sigh came, his entire body tense.

Eve instinctively clutched the hem of Lin Gui's robe.

She looked around, a hint of nervousness appearing on her usually composed face.

Because those sighs seemed to come from all directions.

But all she could see was empty, churning gray fog.

"Should we... evacuate?"

Eve asked in a low voice, her tone very soft:

"We have no guide."

Neither magic nor physical attacks can harm them.

"Most importantly, we can't see it."

Lin Gui's gaze remained fixed as he calmly replied:

No, I can see.

Eve looked at him in astonishment.

Can you see it?

She suddenly remembered her time in Carter's capital—

The scene depicts Lin Gui using blood to create soul dolls to fight against legendary assassins.

There's also the scene of him talking to that bead while it's submerged in the sea.

She blurted out:

"Mr. Lin Gui, can you see souls?"

Lin Gui nodded and said nothing more.

He held Eve's hand tightly, feeling the steady warmth of her palm.

Eve is right, they lack the means to fight against spirits.

At this moment, it was as if a child had mistakenly wandered into the territory of a wolf pack.

They could only hide or turn and run away.

It wasn't far from the lakeside exit; you could even vaguely see the silhouette of Shia looking around.

Lin Gui was confident that if he sensed danger approaching—

Within five seconds, Eve can be carried out of this fog wall.

He stared intently in the direction of the sigh, his pupils contracting slightly.

The mist could not obstruct the observation of the Eye of the Underworld.

However, under the watchful gaze of those on high alert...

The sighs suddenly disappeared.

In Lin Gui's field of vision, the horn of a pale blue spirit demon had just begun to peek out.

Then, as if startled, it trembled violently and quickly retreated into the mist.

They vanished without a trace.

Lin Gui was stunned for a moment, then suddenly turned his head.

I looked in the direction from which a faint ripple was coming from.

From within the gray fog, a blurry, pale blue ghost was "looking" towards them.

Its outline resembles a distorted human figure, but it has no facial features.

At the head position, there are only two hollow depressions, facing the forest ghost eerily.

Lin Gui instantly gathered all his magical power, ready to unleash it.

Adjust the angle of the staff slightly, ready to unleash a burst of speed to retreat at any moment.

But the next second—

The demonic spirit trembled violently, as if struck by lightning.

It let out a short, piercing cry:

"Awooo—!!"

This sound was the complete opposite of the previous sigh.

Sharp, flustered, like a wildcat whose tail has been stepped on.

It then turned sharply and tumbled into the depths of the thick fog.

They vanished without a trace.

Lin Gui: "???"

Eve was also startled by the strange cry, her shoulders hunched slightly and her eyelashes trembled.

She looked at Lin Gui blankly, her eyes filled with confusion:

"What...what was that sound just now?"

Lin Gui remained silent for a long time, unsure how to describe the scene to Eve.

The heavy narration of Blackbeard, the warning of scholar Eli, and the serious admonition of Balin flashed through my mind.

They described the demons of the Wailing Wall as extremely terrifying.

It cannot be seen, touched, or hit.

No matter how strong they are, they are helpless.

Their eerie sighs echoed in my ears at all times.

And now.

Lin Gui had not yet truly witnessed their terror.

The other party just...

Ran?

And it was a very standard, very humane escape?

"What the hell?"

Lin Gui frowned and whispered.

Could it be that the other party is afraid of me? But I'm just a high-level mage.

Or is it that you brought some powerful artifact that would make even a soul demon tremble in fear?

But I don't have anything special on me.

With a puzzled look in his eyes, Lin Gui turned to look at Eve:

"Eve, did you bring anything special?"

"Something that can terrify a soul demon?"

Eve shook her head, her tone serious:

"If I had that thing, I wouldn't hide it, Mr. Lin Gui."

Helpless, Lin Gui could only put this strange scene aside for the time being.

He has now achieved his initial goal of entering the Wailing Wall.

I have confirmed that my Clarity spell can indeed resist the erosion of the fog.

He had no reason to linger in this forbidden land filled with unknowns.

Before leaving, Lin Gui glanced one last time at the direction the soul demon had fled.

Then, holding Eve's hand, they walked through the fog wall in a few steps.

Back by the lake, sunlight streamed down and the wind whispered in my ears.

Xia, who was waiting outside, immediately ran over, her emerald green eyes full of concern:

"How are you? Are you alright?"

Lin Gui nodded and released Eve's hand:

"It's okay, everything's fine."

"The potion Blackbeard provided was indeed effective."

"The problem of the fog within the Wailing Wall has been basically solved."

Shia breathed a sigh of relief, then pressed on with another question:

"And what about the demons?"

Have you encountered those unseen demons?

At this point, Lin Gui's expression became somewhat strange.

He paused for a moment before replying:

"I saw it."

"But maybe they had something to do at home, so they just glanced at us and left."

Shia: "...Huh?"

She blinked, not quite understanding at first.

She then looked at Eve, seeking confirmation.

Eve shrugged; she wasn't quite sure either, because she couldn't see.

All that was heard was a... terrified scream.

It was like...seeing a ghost?
