The deep and majestic sound of the whistle echoed across the sea. The sacred steam gushed out from the core compartment of the ship, shaking the towering chimney of the Sea Mist and every intricate pipe inside it. All the sailors took action as the whistle blew like a war horn.

The elevators creaked, sending propellant bags and heavy shells into the combat ammunition depot below the gun platform. The steam pipes roared, sending holy gas to various key institutions and blessed areas. Sailors moved between decks and corridors, each taking up their combat positions.

When the whistle sounded for the second time, the bronze bell in the chapel at the stern of the Sea Mist rang, symbolizing the blessing of the Storm Goddess, allowing the gift of Gemona to descend on this terrible warship that was regarded as a "curse" by the world.

On other main battleships of the Sea Fog Fleet, similar bells and whistles also rang out one after another - the bells of the ship-borne churches echoed in the fog, vaguely seeming to produce a mysterious resonance, and the bells playing in unison even began to interfere with reality, causing the thick fog on the sea to show signs of fading and dissipating.

At the same time, along with the actions of the Sea Fog Fleet, the Frost Navy patrolling in the nearby patrol waters also responded - flags were raised, lights were flashing, and the sound of whistles and the bells of the ship-borne church echoed in the fog like a reflection!

At this moment, half a century of entanglement and hostility between the two fleets finally gave way to the strange phenomenon that descended upon everyone's head. Under the blockade of the strange and dangerous fog, the navy established by the living and the fleet dominated by the undead have become the only forces that can still rely on each other.

No one knows when and in what form the enemy will appear, but everyone knows that every strange ship that appears on the sea next is an enemy.

In fact, every "friendly ship" that refuses to respond to communications is also an enemy.

The enemy is the sea itself.

Everyone's nerves were tense, waiting for changes in the fog, waiting for new news from Frost Island, or any other possible intelligence and instructions. This depressing wait lasted for an unknown amount of time, and Tirian, who was in command on the Sea Mist, suddenly had a strange feeling.

He seemed to feel a gaze, but this gaze did not come from any specific direction - it was as if it was a gaze that spanned time rather than space, coming from the distant past and falling quietly on him.

He raised his head in astonishment and subconsciously looked around the bridge of the Sea Mist.

First mate Aiden was communicating with the boatswain, the communicator was communicating with the Frost Navy about the coordinates of their respective ships, and the old black-robed priest had rushed over from the chapel and was now praying with his eyes closed beside the gunnery chief's seat - the thick fog blocked the view of the sea, and the priest's spiritual guidance would be the warship's greatest reliance in fighting the enemy in the fog.

And further away, a figure was standing quietly by the porthole.

In a trance, Tirian recalled a scene half a century ago - in that yellowed memory, Her Majesty the Queen had personally boarded this warship. At that time, the Sea Mist had not yet experienced the growth of these fifty years. It still had a more ancient and more vicissitudes of life appearance, and the Queen stood there, gazing at the distant sea for a long time.

From there, she issued an order for the Sea Mist Fleet to move away from the Frost in three days.

Now, the figure slowly turned his head and issued another order.

"Tirion, defend the Frost."

Half a century later, the second order finally arrived.

Tirian woke up suddenly, feeling his heart pounding, his eyes burning and stinging as if he had looked directly at some knowledge close to the "truth", and the noise in his mind roared and shook. Before he could think carefully about whether the scene he had just seen was an illusion or something else, a sharp alarm suddenly rang on the bridge, interrupting all his thoughts.

As the ringing sounded, he had already seen the scene on the distant sea out of the corner of his eye - in the mist, a huge ship was emerging from the thick fog, as if the sea itself was bulging upwards, shaping a ghost of the past.

The "ghost" had a towering mast and an old-fashioned chimney structure like coral growing on the back of a sea beast. It was slowly adjusting its direction and moving toward the flank of the Sea Fog Fleet.

So close that even the spiritual guidance of a priest is not needed.

"Visual unit appears! Silhouette identified, third-party ship!" the observer shouted loudly.

"Open fire," Tirian walked back to his captain's seat, his voice as majestic and cold as an iceberg, "Except for the ships already on the identification list, everything that appears on this sea is an enemy."

In an instant, cannons roared and thunder exploded!

On the Sea Mist, the three main turrets that were at the best shooting angles launched bombardments one after another. The heavy armor-piercing shells that had been ready for launch flew out of the barrels amid thunder, and turned into a flaming meteor falling from the sky in the thick fog, smashing hard into the shadow of the ship that appeared in the fog in the distance!

Almost at the same time as the Sea Mist launched its attack, continuous artillery roars were heard in the fog - it sounded like distant thunder, and in a series of flashes of fire, lines of fire cut through the fog and rushed towards the sea where the Sea Mist was located.

Tirian sat quietly in the captain's seat, squinting his eyes slightly, listening to the distant roar and calculating the flight of the shells.

It’s the old-fashioned 356mm main gun, with four triple-mounted guns… Which old friend is it?

The Duke of Loon, which once performed the mission of protecting the queen? Or the Knight, which bravely fought against the children of the deep sea in the storm and sank? Or... the Warrior?

The whistling sound was like the wail of a banshee. The thunder falling from the sky shattered the remaining calm on the sea surface. The huge explosion stirred up water columns dozens of stories high. Even the thick fog lingering on the sea surface was torn to pieces by the shock wave, turning into countless pale turbulences.

None of the shells flying from the other side of the thick fog landed near the Sea Mist, and the same was true for the Sea Mist's first round of shelling.

"It's the Knight. Pay attention to its broadside rapid-fire guns," Tirian opened his eyes. His voice was not loud, but it was clearly heard by every soldier. "This distance is enough for the rapid-fire guns to exert their power. Pressurize the steam core and increase the distance."

"Yes! Steam core pressurized! Keep your distance!"

The "heart" deep inside the Sea Mist let out a low roar, and the entire ship began to accelerate and slowly turn. On the nearby sea, large pieces of floating ice also began to emerge rapidly, spreading rapidly in all directions like some kind of living thing, creating a battlefield that was favorable to the Sea Mist.

Just as the ship began to maneuver, Tirian suddenly noticed from the corner of his eye that there was another fire outside the porthole on the other side, accompanied by a distant shadow.

First mate Aiden immediately shouted: "Second ship found, no response on the radio, not on the identification list!"

Before Aiden finished his words, another low roar came from afar.

"Third ship! Not on the identification list!"

"The Sea Raven has received a transmission, they have engaged multiple enemies!"

"The Frost Navy has sent a communication that a battle has broken out near the city-state!"

"The first and second main guns should deal with the Knight first, and the third main gun and long-range secondary guns should deal with other enemies that appear in range." Tirian's voice did not change at all because of the continuous appearance of enemies on the sea. He just continued to calmly watch the ship in the deep fog that was still firing and approaching this side on the ice. "Don't worry about how many enemies there are - all the strange things that appear on the sea are enemies. This is just the beginning."

First mate Aiden also spoke loudly: "Listen to the captain, we have to fight whatever appears on the sea. Even if these old guys are alive, they are no match for the Sea Fog Fleet. Keep firing!"

Following the orders from the bridge, all the main and secondary guns of the Sea Mist began firing rounds of salvos, and the scorching flames ignited the dark and chaotic fog again and again.

Amid the roar of artillery fire, more unidentified ships began to appear on this vast sea!

As Tyrian said - this is only the beginning.

The mirror frost is rising, the border of reality is blurring in the fog, and things that once sank in this sea are entering reality on a large scale in the form of replicas!

And everything that appears on this sea from now on is an enemy!

"Let's have a big fight!" Aiden's loud voice was shouting on the bridge. The bald man had an almost ferocious smile on his face. It was obvious that he hadn't had such a hearty fight for a long time. "Let's vent all the anger of the past fifty years, brothers, and open the eyes of those sissies in the navy! Let them see what the Sea Mist Fleet is..."

Suddenly, the first mate's noisy voice stopped abruptly, and he seemed to be strangled by an invisible hand. He suddenly opened his eyes wide and stared in a certain direction - and the next second, Tirian knew why he reacted like this.

Another ship suddenly appeared in the dense fog nearby, and then rushed into the battlefield at a speed almost as fast as lightning. The ship was different from any enemy that had appeared so far, and different from any famous ship that Tirian knew.

It was a solid black fog, a tangible shadow, a hazy nothingness that looked like a ship! It broke through the fog like some weird shadow reflected in a mirror, rushing straight towards them. But what made the crew of the Sea Mist even more terrified than the weird shape of this "shadow ship" was the "shadow" of the ship reflected in the sea.

It was actually another ship, a "ghost ship" surrounded by dark green flames. In the eyes of all members of the Sea Fog Fleet, it was more bizarre and terrifying than a phantom!

The "twin ships" with the sea surface as their mirror suddenly appeared and rushed across the sea with a roar. One ship was emitting billowing black smoke above the sea surface, and the other was emitting faint green fire under the sea surface. It almost brushed past the side of the Sea Mist and reached the other end of the battlefield in the blink of an eye.

Tirian dared to swear to his father that he had never seen a large ship with such an outrageous speed in his life!
