Hello, is this a letter addressed to Demon Fortress?

The trackless train hovered over the Dusk Fortress for a full half hour.

It sometimes turns nimbly like a swimming fish, and sometimes hovers motionless, like an aerial fortress.

Until Lin Gui's forehead was covered in fine beads of sweat and his face turned slightly pale.

Eve, who was behind him, also began to breathe rapidly, clearly indicating that she had expended a lot of energy.

Half an hour of high-intensity maneuvering enabled this hundred-ton steel behemoth to move flexibly in the air.

This consumed more than just Lin Gui's magic power.

Even Eve, who was constantly replenishing his magic, was feeling extremely tired.

When the train finally slowly returned to its original position with a heavy thud, everyone seemed to wake from a dream.

Lin Gui wiped the sweat from his brow and looked at the dumbfounded members of the North Wind Caravan around him.

"Well? Do I need to be tested again?"

His voice was calm, yet carried an undeniable confidence.

Scholar Eli pushed up his glasses and exchanged a look of amazement with the forest elf Lysa.

Lysa's lips curled slightly, her tone tinged with a hint of teasing:

"How about we just kick Betty out?"

She glanced deliberately at Betty, who was puffing up her cheeks, and continued:

"Compared to the little mage's levitation spell..."

"Someone's levitation technique starts so slowly it's like they're crawling."

"It's always difficult to control, and it keeps veering off course."

Betty immediately retorted with her hands on her hips:

"Hey! Lysa! I'm not that bad!"

"I practice every single day, okay!"

Lysa shrugged and smiled.

"Is that so? To me, you seem to have made no progress at all."

Betty gave a soft hum.

His eyes darted around as he thought to himself.

When I first arrived, I asked the young monk for a lot of tips and tricks.

I'll show you my brand new levitation technique in a bit!

The two started laughing and joking around, and the atmosphere immediately became much more relaxed.

The other team members around him also smiled, and their gazes toward Lin Gui held a newfound level of approval.

Lin Gui's display of levitation skills brought them an unprecedented sense of security.

At least during this perilous journey, they no longer had to live in constant fear.

They were terrified that Betty might mishandle the situation and cause the whole team to crash into a cliff or fall into a deep abyss.

Vice-captain Aubrey stepped forward with a smile and patted Lin Gui on the shoulder.

"Very good, very good, your levitation skills have truly opened our eyes."

He turned around and gestured for them to proceed.

"Please come with me, I'll show you our temporary lodgings."

The last carriage of the trackless train was particularly crowded.

The ground was covered with heavy wooden crates, filled with goods to be sold to the dwarves.

The space originally reserved was quite spacious, but the deputy captain obviously did not expect Lin Gui to bring so many supplies.

After Lin Gui neatly stacked the boxes on the raft inside, the remaining space suddenly became very limited.

It would be fine if three men squeezed together, but it's an awkward combination of one man and two women.

Aubrey glanced at the cramped space and suggested:

"Should we adjust the accommodation arrangements?"

"Let your two female teammates live with Betty and Lysa."

"Should I bring the scholar Elie and the barbarian warrior Barton over here?"

Lin Gui shrugged helplessly; he had indeed overlooked this problem.

Just as he was about to nod in agreement, Shia suddenly spoke first:

"No need! I don't need to change!"

Lin Gui frowned and looked at her, only to see Xia gripping his arm tightly, her eyes shining:

"Don't worry, Lin Gui, I won't look down on you!"

The joy in her tone immediately made Lin Gui understand her thoughts.

Recalling that night in the capital when they tried to drug him, he couldn't help but shake his head helplessly.

Shia leaned close to his ear and whispered in a voice only the two of them could hear:

"Please, I really don't want to live with her."

Lin Gui knew that "she" referred to the forest elf ranger.

He could only give the vice-captain a helpless smile:

"She doesn't need to. We... have that kind of relationship."

Aubrey's gaze shifted between Shia and Lin Gui, a meaningful smile appearing on his face.

"I understand, I understand. And this person..."

Unexpectedly, Eve gracefully clasped her hands in front of her and smiled gently:

"That kind of relationship is also between him and me."

Lin Gui raised an eyebrow and looked at Eve, meeting her smiling eyes.

He recalled her unusually intimate gestures and aloof attitude after the assassination attempt.

This time, he did not refute it.

Perhaps this is a good opportunity to ask this holy lady why she treats him so specially.

The atmosphere among the three people in the cramped carriage suddenly became subtle.

Vice-Captain Aub glanced at Lin Gui and the two women beside him with a strange expression.

In the city-state era, polygamy or polyandry was indeed not uncommon.

But looking at Lin Gui's slightly helpless expression, he felt that things were not so simple.

Just as he was about to speak, the ground beneath his feet suddenly trembled.

The trackless train swayed, and the faint roar of a demon echoed from afar.

Aubrey's expression turned serious as he looked towards the city walls:

"It looks like we can set off soon."

He turned to Lin Gui: "Want to go take a look together?"

"It's not often we see Captain Freya casting her spell with all her might."

Lin Gui nodded and followed with Shia and Eve.

The scene on the city wall was quite eerie.

Archers, mages, and even alchemical cannons were all stationed beneath the city walls.

Fully armed soldiers stood guard outside the fortress gate.

Only Freya and Rhodes stood side by side on the wall.

Shia pointed curiously at the ranged professionals guarding the city walls:

Why didn't they climb the city walls?

Lin Gui answered calmly:

"Because they don't need to take action."

"They just need to wait for the battle to end and clean up the battlefield."

He paused, his tone carrying a deeper meaning:

"On the battlefield, no class can be more effective than a mage who goes all out."

At that moment, Freya's chanting drifted on the wind.

It was an ancient and melodious rhythm, each syllable containing a powerful magic.

Her long, icy blue hair moved without wind under the influence of magic, like a flowing glacier.

Those deep blue eyes were even more profound now, as if they contained ice and snow that had never melted for millennia.

As she sang, tiny ice crystals faintly appeared around her, highlighting her delicate face, making her look like an ice goddess descending to earth.

Her voice was clear and cold, yet carried an undeniable authority.

Rhodes stood guard in front of her, sword in hand, vigilantly protecting her.

Meanwhile, the view in the distance was breathtaking.

A dark mass of demons surged in like a tide, their ferocious roars deafening.

The demon at the forefront suddenly stopped, and tried to retreat in terror.

But the surging torrent of demons from behind relentlessly pushed them forward.

The demons stormed the stone wall, piling it higher and higher like stacked building blocks.

The grimoire in Freya's hand emitted a dazzling blue light.

A giant magical ring with a diameter of over twenty meters appeared in front of her.

As the chanting grew louder and louder, the rings spun and expanded rapidly.

A biting chill and a fierce wind seeped out from it.

Standing on the city wall, Lin Gui could clearly sense—

The wind and ice magic in the air is surging wildly.

The demon at the forefront let out a desperate wail.

They trampled on each other, but could not stop the approaching footsteps.

In the blink of an eye, the demons at the forefront had piled up and climbed the city wall, rushing towards Freya, who was still chanting.

A golden light flashed, and Rhodes' longsword was swung out, instantly tearing the oncoming demon to shreds.

However, more demons climbed up the fortress, including many large and powerful individuals that exuded a terrifying aura.

The city walls began to shake under their impact, and rubble fell in a flurry.

The defense line was about to be breached—

At this critical moment, Freya's chanting reached its peak.

"Ice and Snow Frenzy"

She whispered the magic's true name, a cold glint flashing in her azure eyes.

In an instant, the entire valley was enveloped in a blinding blue-white light.

A frigid storm swept through, instantly freezing thousands of demons.

The sound of ice crystals shattering echoed continuously, resounding through the sky.

The frozen demon shattered like fragile glass.

The once bustling battlefield instantly fell into dead silence.

Only the howling of the cold wind across the icy plains echoed through the valley.

The fortress gates slowly opened.

Fully armed mercenaries, adventurers, and knights swarmed out.

They charged at the remaining, struggling demons, unleashing a torrent of swords and magic.

Shea stared in awe at the valley that had suddenly turned completely white.

She gently patted Lin Gui's shoulder:

"When will you be able to cast such powerful magic?"

Lin Gui gazed at the still-scattering ice crystals in the distance and smiled slightly:

"Don't worry, it won't be long."

His tone was calm, yet carried an undeniable certainty.

Snowflakes drifted down from the sky and gently landed on his shoulder.

In the afterglow of the setting sun, the entire frozen valley glowed with a faint golden light.

This raging tide of demons was thus completely ended by a legendary spell.
