Hello, is this a letter addressed to Demon Fortress?

This state of readiness is completely different from when we crossed the border of the silent sea on the way here.

The reason lies in the vastly different marine environments on both sides.

At this moment, the sea area near the city of Jiandun is a small area surrounded on three sides by the Silent Sea.

The demons trapped here have become exceptionally cruel and tyrannical in order to survive.

They might even break free of the sea to attack land creatures.

The most terrifying thing is that one of the deep-sea demons carries a horrific plague virus.

The consequences would be unimaginable if it were to spread.

This is one of the key reasons why the fortress city of Shield was built here.

As the train crossed the invisible boundary, Lin Gui immediately sensed a tremendous change.

The "sinking" principle disappeared, and a tremendous buoyancy surged up from below!

"Hurry up!"

He gave a low shout and activated the levitation technique at full power.

The entire train seemed to be being pushed upwards by an invisible giant hand.

It begins to rise rapidly while enveloped in bubbles!

This speed far exceeds the speed of sinking.

The seawater was rushing backward, forming countless turbulent eddies.

The bubbles were violently deformed by the water flow, emitting a humming sound as they struggled under the strain.

"Pay attention to defense!" Poseidon's voice sounded somewhat distorted as it rose rapidly.

"They will pass directly through the bubble!"

Before the words were even finished, several dark figures had already pierced through the bubble barrier and rushed straight towards them.

Bubbles can only block seawater, but they can't stop these ferocious predators.

Freya managed to keep her balance amidst the rapid ascent and turbulence.

However, in the deep sea, the effectiveness of her stealth magic is greatly reduced.

The complex aquatic environment also limited her ability to cast large-scale spells.

This strongest fighter is unable to exert his full strength at this moment.

Poser quickly changed tactics and expanded the bubble.

Although it is thinner, it provides a more open fighting space.

"Intercept them!" Freya calmly ordered amidst the violent shaking.

Lysa's arrow was fired with precision, piercing the throat of a serpent demon even amidst the rapidly rising turbulence.

Shia's arrow, imbued with her inner energy, shattered the giant crab demon's shell.

Alvin and Duru weaved through the swaying carriages, their daggers precisely piercing the vitals of the small demons.

The barbarian warrior Barton roared and smashed a hammerhead shark demon away with his warhammer.

Lin Gui planted his feet firmly on the front of the vehicle, doing his best to maintain stability as it floated upwards.

At the same time, he distracted himself by using levitation to cleverly flip over several burrowing demons.

The ascent turned into a fierce underwater battle during the rapid ascent.

Demons relentlessly attacked through the bubbles, and the warriors fought desperately to fend them off as the train rapidly ascended.

Within the bubble, swords flashed and magic clashed with arrows.

Everyone was on edge, engaged in a life-or-death struggle amidst the rising turbulence of the deep sea.

As the ascent speed increased, the color of the seawater above began to change from jet black to deep blue.

The faint light pierced through, illuminating countless hideous demonic figures outside the bubble.

This deep-sea breakthrough battle is accelerating towards the surface!

As they rose faster and faster, the rapid changes in water pressure caused tinnitus, which made everyone extremely uncomfortable.

The offensive became increasingly fierce.

As they approached the sea, the light intensified, revealing even more distorted and grotesque figures.

Several enormous deep-sea trolls also joined the pursuit.

They rammed violently against the train, their claws scraping against the metal with a piercing sound.

The bubble trembled violently under the continuous attacks, as if it would burst at any moment.

Lysa's quiver was half empty, and Shia's breathing became rapid.

Alvin had a deep, bone-revealing wound on his arm, but he was still gritting his teeth and persevering.

Everyone has reached their limit.

At this critical moment.

Suddenly, the whole world seemed to be lit up.

"BOOM!!!"

The entire train, carrying tens of thousands of tons of seawater, burst through the surface of the sea like a giant whale breaking free of its cage!

Huge waves surged into the sky, then turned into torrential rain.

The blinding sunlight instantly filled every corner.

Eyes accustomed to the eternal darkness of the deep sea were stung painfully by this sudden burst of light.

People instinctively closed their eyes or raised their hands to cover their eyes, their movements momentarily halting.

And it was during this brief period of adjustment that...

Some of the aquatic demons that were swept out of the sea by the train shook off the seawater.

Its scarlet eyes immediately locked onto its "prey" that was within arm's reach.

Slippery tentacles and sharp pincers, carrying a stench, are about to pounce on the temporarily unsuspecting crowd!

"Everyone! Get down!"

Freya's cool voice suppressed the chaos.

She was already standing in the middle of the train, her robes swaying in the sea breeze.

Lin Gui felt a sudden weight on his shoulder as he was firmly pressed against the car floor by the scholars Ellie and Betty beside him.

On the other side, Shia was also tackled by Lysa without hesitation, who shielded her with her body.

Almost at the same moment that everyone collapsed.

Freya opened her arms, and a powerful surge of magical energy erupted from her center!

"Wind Blast!"

There are no lengthy chants, only concise truths.

An invisible circular shockwave rapidly expanded outwards from her center.

The air was compressed violently, producing a low hum.

Those sea monsters that have just leaped up or are about to pounce.

It was like being struck head-on by an invisible giant hammer.

Its massive body suddenly stopped, then flew backward uncontrollably.

They let out mournful cries, tracing chaotic arcs through the air.

One after another, they crashed into the sea around the train, splashing up countless murky water droplets.

Some of the weaker demons even disintegrated in mid-air.

The sea has temporarily returned to calm.

The blinding sunlight shone on the wet train and the still-shaken crowd.

In the silence after the disaster, only the sound of waves crashing against the car and people's heavy breathing remained.

After a brief silence, cheers erupted.

"We're out! We're really out!"

Betty excitedly grabbed the scholar's arm, jumping and laughing.

Even the usually composed vice-captain Aubrey showed a relieved smile and patted the barbarian warrior Barton's sturdy back forcefully.

The orc Grom let out a deep, satisfied growl.

Shea breathed a long sigh of relief, only then realizing that her hands were still trembling slightly.

She looked at Lysa, who had just protected her, and Lysa had already stood up nimbly and was checking the bowstring.

Noticing Shia's gaze, Lysa nodded slightly in response.

"Don't relax too soon."

Freya's voice remained cool and aloof, but her taut shoulders had subtly relaxed.

The grimoire in her hand moved automatically without wind, and icy blue magic flowed once more.

"A veil of concealment covers my tracks."

After a brief incantation, familiar magical fluctuations enveloped the entire wet train.

The car body began to blur above the sea, appearing and disappearing intermittently.

"Lin Gui," she said, turning towards the front of the car, "I'm leaving him to you."

Lin Gui nodded without saying anything more.

He took a deep breath of the salty sea breeze and gripped his staff tightly again.

With skillful manipulation of levitation, the train smoothly changed direction.

It drifted steadily toward the faintly visible, dark brown outline of the coastline in the distance.

The sunlight was dazzling, but it was no longer uncomfortable.

The sea breeze caressed everyone's soaked clothes and hair, bringing with it the long-lost scent of the "outside" world.

Despite the fatigue, a relaxed atmosphere finally truly permeated the team.

They succeeded.

It broke free from the eternal darkness and deathly silence of the silent sea.

Shea leaned against the side of the carriage, watching the land getting closer and closer, and the corners of her mouth unconsciously turned up.

Even Eve, who usually has little expression, squinted slightly, enjoying the warmth of the sunlight.

Only Lin Gui, while controlling the train, subconsciously touched the beads in his pocket.

Deep in his eyes, a trace of doubt had not completely dissipated.

But in any case, Shield City is just ahead.
