Hello, is this a letter addressed to Demon Fortress?

Grom's overwhelming offensive quickly emptied the nests that had plagued the Shield City for years.

One hammer blow after another.

Those lumpy buildings collapsed like mud, with purple sap flowing everywhere.

The demon cubs fell in droves, their purple blood flowing like rivers.

In less than fifteen minutes, no living demons could be seen in the entire area.

Lin Gui controlled the train, which slowly floated downwards.

stop.

He was about to jump when Barna grabbed him.

"Don't move."

Barna raised his chin, gesturing for Lin Gui to look around.

A faint purple mist floated in the air, ethereal and indistinct, like a ghostly veil.

"These are all poisonous mists from the cursed demons of the deep sea."

Barna’s voice was low.

Even if the cursed demon dies, the poisonous fog will persist for some time.

He paused.

"This thing is very troublesome."

"Once infected, the skin will fester and rot."

"Without a powerful priest to heal, it's basically death."

He looked at Lin Gui.

Even those who are extraordinary are not immune.

"Stay by my side and don't leave."

"Leave the rest to Grom and the craftsmen."

Lin Gui looked down.

Grom and the artisans were walking through the poisonous fog, completely without any protection.

Grom opened the train carriages and unloaded the heavy supplies one by one.

The star stones and parts felt as light as toys in his hands.

The craftsmen then took the barrier stones given to them by Balin and began to deploy them on the island.

A hint of doubt flashed in Lin Gui's eyes.

Barna laughed.

"The poisonous fog is terrifying, but its maximum damage is only at the lower level of the extraordinary realm."

He pointed to the craftsmen.

"Every single one of the craftsmen I brought is an extraordinary being."

He paused.

"To build a fortification capable of impaling a deep-sea demon within two days, both strength and craftsmanship are indispensable."

Lin Gui nodded.

Under the watchful eyes of the two men, the craftsmen began to work.

A barrier stone was embedded in the ground, emitting a faint glow.

Then the second piece, the third piece...

As the barrier stones were deployed, a faint light curtain began to form in the air.

Like an inverted bowl, it covered the area where the fortifications were to be built.

Inside the barrier, the purple poisonous mist was gradually pushed out.

The craftsmen used the barrier stone to tear open the barrier, entered the light curtain, and began to move the stone slabs to build the foundation.

Their movements were extremely fast and precise; every step looked like it had been rehearsed hundreds of times.

The heavy stone slabs felt as light as a feather in their hands.

They were stacked up one by one, climbing upwards at a speed visible to the naked eye.

"alright."

Barna patted Lin Gui on the shoulder.

"Let's go back quickly."

"The sooner we deliver all the supplies, the sooner we can relieve the pressure on Shield City."

He looked down at Grom.

"I'll leave this to him."

Lin Gui nodded.

Then he said to Barna.

"Take my flying boat; it'll save you some time."

……

On the other side...

The battle between Balin and the other dwarven pillars is raging outside the south gate.

Lin Gui said that it would only take half a minute to move them.

But Bahrain and the others held off several epic demon lords for a full five minutes.

Hopefully, this will ensure the smooth operation of Lin Gui and his group.

In five minutes, they fought their way in and out of the overwhelming horde of demons, their bodies covered in blood and their energy depleted.

at last.

A figure burst out from the horde of demons.

Bahrain was covered in blood, and his plate armor had several deep claw marks.

But he didn't stop, leading the way and rushing towards the city gate.

Behind them, several other dwarf pillars also rushed out one after another.

Some had broken arms, some had cuts on their faces, but they were all alive.

The city gates slammed shut behind them.

The light barrier around the city gate closed again.

boom--! ! !

A gigantic demon lord crashed into the barrier.

The entire city of Fortified Shield trembled.

The rubble fell from the city wall, the houses on the street creaked, and the tremors could be felt even deep in the mountains.

one more time.

boom--! ! !

The city's residents huddled together in their homes, their faces filled with worry.

The children covered their ears, and the adults gritted their teeth, remaining silent.

Only the distant sounds of artillery fire and impacts proclaimed the terror outside.

Even though Bahrain didn't say much about the threat the Black Tide posed to Shield City.

But they could all guess some of it.

Meanwhile, in Bahrain's forging workshops.

The little dwarf who tended the boiler huddled in the corner.

He clutched a rough amulet tightly in his hand.

He closed his eyes, his lips moved, and he muttered something.

"God of forging above... bless the fortress lord... bless those adults... bless that black-haired human..."

"May they all return safely..."

South Gate.

Bahrain leaned against the city wall, panting heavily.

Several priests surrounded him, their holy light continuously flowing into his wounds.

The flesh torn apart by the demon's claws is slowly healing.

The other pillar dwarves are also receiving treatment.

Some were lying down, some were sitting, and all of them looked terrible.

Bahrain looked up at a messenger not far away.

"How's the situation at Ximen?"

His voice was hoarse and weary.

Just as the messenger was about to answer, a dwarf pillar beside him offered words of comfort:

"Don't worry, Fortress Master."

"At least I didn't notice the train crashing..."

"Those vehicles, as long as snakes, would be easy to spot if they failed and crashed."

"So, they must have made it out successfully."

Before he could finish speaking...

A calm voice rang out from the side.

"right."

"The first batch of supplies has been delivered."

That voice was so familiar.

Bahrain turned his head sharply.

Then, he froze.

The other dwarf pillars were also stunned.

Lin Gui stood not far away, watching them with a calm expression.

Beside him, Barna was pale, dazed, and his eyes were unfocused.

Finally, Barna couldn't hold back any longer.

He staggered to a steel pillar and grabbed it for support.

"vomit--"

I vomited so badly I felt dizzy and disoriented.

Bahrain opened his mouth wide, unable to utter a word for a long time.

"Why...why are you still here?"

His voice even changed tone.

"Weren't they supposed to be transporting supplies?"

Lin Gui looked at him, his expression still indifferent.

"The first batch has already been shipped."

Balin and the other dwarf pillars: "..."

"Is it delivered?"

Bahrain's voice sounded like it was being squeezed out from between his teeth.

"What do you mean?"

Lin Gui was stunned for a second.

Then, he slowly said:

"It's about safely bringing the supplies to Jardine Island, unloading them, and then flying them back."

"That means the first batch has already been delivered."

"All delivered?"

Bahrain's voice even changed tone.

He and the other dwarf pillars froze for a moment, then all turned to look at Barna.

Barna leaned against a pillar, just recovering from the shock.

He looked up at Bahrain, his face still deathly pale.

"Yes, all delivered."

After he finished speaking, he lowered his head again.

"vomit--"

I vomited even more violently.

Bahrain:"……"

Other dwarves: "..."

As Barna vomited, he cursed under his breath.

It took them about four minutes to reach the island of Shield.

proceed with extreme caution, as if walking on thin ice.

Walking through that overwhelming horde of demons, every step felt like dancing on a knife's edge.

When they returned, there were only Lin Gui and him, as they were not carrying any weight.

Lin Gui then suggested that they take his flying boat.

Barna, after all, was a dwarf and skilled in blacksmithing.

Look at the wind pressure cannon mounted on the back of Lin Gui's flying boat, combined with its design specifically for speed.

He could indeed predict how fast the little thing would go once the wind pressure cannon was activated.

But he thought about all the demons on the way back.

The young monk will also show some consideration, just like when he arrived.

Control your speed to avoid crashing into those monsters in the sky.

result.

The opponent fired a wind pressure cannon.

Full horsepower.

overload.

hurricane.

There was no slowdown.

Not even once.

Barna had just finished fastening his seatbelt a second ago, and the next second...

whoosh-

A white light streaked across the sky.

He only felt a blur before his eyes, and all the demons around him turned into blurry light and shadow, and then...

Before I knew it, we were already in the city...

Balin and the other dwarf pillars stared blankly at the Forest Ghost.

Just moments before, they were worried about the safety of Lin Gui and the others.

The other party returned shortly after.

They returned unharmed.

Lin Gui looked at their injuries.

The deep claw mark on Bahrain's chest was still bleeding.

A dwarf next to him had his entire arm in a sling.

The other one had his forehead wrapped in gauze, and blood was still seeping down.

He paused for a second.

"Um... the second batch of trains is almost loaded."

He paused.

"Would you... like to rest for a while?"

grunt.

Bahrain swallowed hard.

He and the other dwarves exchanged glances.

It was hard to tell whether his eyes held relief or embarrassment.

Suddenly, they realized that they had deliberately held out for four minutes longer than expected in order to cover for Lin Gui.

He's like a fool.

There was a moment of silence.

Bahrain coughed lightly.

"Ahem, um..."

He looked at Lin Gui.

"You said before that the transfer would only take a few seconds?"

Lin Gui replied:

"It will only take half a minute."

He glanced at the injuries sustained by Bahrain and the others.

"If all else fails, twenty seconds will do."

Bahrain's lips twitched.

He took a deep breath, turned his head, and looked at the dwarf pillars around him, who were also wounded.

"Can we still fight?"

"able!"

"Walk!"

Bahrain stood up, picked up his battle axe, and strode outside.

……

Simon.

The new train has been loaded, its long, narrow body lying on the ground like an iron dragon waiting to awaken.

Lin Gui led Barna back to the front of the car.

Behind them, the massive iron gate slowly opened.

The roar of cannons and the howling of demons filled the air.

The train took off again.

……

This time, when Lin Gui arrived at Jiandun Island with the train again, the situation had changed.

The area where Grom and his group had built was now covered with demons.

They were densely packed, like ants, covering the pale blue light curtain.

What's most chilling is...

An epic demon lord is repeatedly striking the barrier with terrifying attacks.

boom--!

boom--!

With each impact, the barrier trembled violently, its light flickering unpredictably, as if it might shatter at any moment.

The appearance of the epic demon disrupted their plans.

Barna frowned and looked at Lin Gui.

"Can your magic fool this lord?"

Lin Gui shook his head.

"If I get close, it will definitely find me."

He looked at the enormous creature.

"But don't worry."

He paused.

"There's only one, that's easy to solve."

Barna was taken aback.

"How do we solve this?"

Lin Gui said calmly:

"You and I will go and lure that demon away."

Barna frowned.

"What about the supplies?"

Lin Gui's expression remained calm.

"Let it pass by on its own."

Barna: ? ? ?

He stared wide-eyed at Lin Gui as if he were a madman.

"Go there yourself??"

"Can it grow wings and fly there on its own?"

Lin Gui offered no explanation.

He took immediate action.

Board the airship and leave the train.

Then, Barna witnessed a scene he would never forget.

The massive, tens-of-meters-long structure did not fall even after Lin Gui left.

It just hovered in mid-air.

Then, it slowly turned in a different direction.

Hovering in the sky.

As if it had truly come to life, it floated there, awaiting Lin Gui's command.

What puzzled Barna even more was...

The concealment magic cast on the train did not disappear after Lin Gui left.

The demons still hadn't discovered its existence.

After finishing everything, Lin Gui maneuvered the flying boat and looked at the epic demon lord who was attacking the barrier.

"I need a usable legendary attack spell."

Barna took a deep breath to suppress his shock.

He raised his staff.

The chanting began.

Brown magical light converged in front of the airship, and a huge magical ring quickly formed.

The ring was engraved with intricate runes, nested layer upon layer, rotating, growing brighter and brighter, more and more dazzling.

Lin Gui gripped the flying boat tightly.

It accelerated suddenly.

The airship, like a streak of light, rushed straight toward the epic demon.

The moment of approach.

Barna pointed his staff forward.

The magic ring suddenly exploded, and a huge earth spike materialized out of thin air, slamming into the demon with overwhelming force.

boom!!

The epic demon staggered from the impact, letting out a deafening roar.

It suddenly turned its head.

Those blood-red eyes were fixed on the flying boat.

Lin Gui's lips curled up slightly.

The airship suddenly turned and sped towards Shield City.

The demon roared and leaped from the edge of the island, crashing into the black sea and creating towering waves.

Then, the pursuit began on the sea.

Its enormous body swam in the seawater at an astonishing speed.

Like a runaway warship, it cleaved through the black waves, frantically chasing the flying boat.

As it swam, it let out a low, angry roar.

And just as they left.

The train that had been waiting in the air finally moved.

It drifted silently towards the barrier.

It then plummeted out of control.

It is clear that the maximum distance that Lin Gui can control has been reached.

Not only the levitation spell that had been cast on it disappeared, but also the veiled robe in the dark night.

The exposure of the train alerted the demon instantly, and it pounced on it.

But the train's weight of 100 tons overwhelmed everything.

It overwhelmed all the demons that tried to stop it and crashed straight into the barrier.
