Guns roared, steam traps drove heavy mechanical spiders to spin, six-barreled machine guns spun and spewed tongues of fury in all directions, sweeping through the monsters that kept emerging from the fog like a harvest, and every now and then bullets flew from the fog and struck the armor of the walkers and the sandbags of the barricades.

Among the monsters are also "soldiers", there are heavily armed soldiers, and even walking mechanical spiders with black mud.

And as the battle continues, so do these dangerous enemies.

"These *** things are copying us!"

A soldier in a breathing mask hid behind a barricade, shouting angrily as he frantically pulled the trigger, his metal armor already scarred,

The power pipes at the armor joints were broken, and hissing steam poured out of the valves, and on the steam pack behind him, the logo of the elite garrison of the Frost City-State could be seen.

"They're not the only ones who copy us," the squad commander said loudly, his voice hoarse and dark behind the breathing mask - the fog in the streets is getting worse, and in order to avoid the possible toxic gases in the fog, the garrisons who are now entering the war zone on a mission have put on these formidable breathing masks, "Everything that appears in the fog is an enemy, an enemy!"

"I just saw a group of people running past the intersection in front of me!" Another soldier suddenly shouted, "It looks like an armed civilian—a sailor on a ship!"

"I saw it too, it was blurry, they were like burning, but the fire was green!

The team commander raised his head when he heard this, but in the next second, a strange whistling suddenly came from the other side of the dense fog, carrying a sharp sound of death.

A grenade pierced through the fog, crossed the gap between the barricades, and fell directly at the feet of the steam walker, without any time to react, the grenade exploded, and shrapnel rained down.

The thin metal cuirass could not withstand the deadly impact at such close range, and the squad commander was blown away along with his own soldiers.

It didn't take long for him to regain a little consciousness in a trance, and out of the corner of his eye, he saw the steam walker staggering down, its armor torn, all the power pipes spewing white mist, and the last remaining machine-gun turret spilling the last barrage in the dumping.

Countless shadowy things emerge from the fog and rush to the next intersection.

The team commander slowly squirmed, clutching a grenade that had been pulled open, and he couldn't remember when he got it—maybe when he was blown up, or maybe it was a knee-jerk reaction when he lost consciousness.

Feeling that he had exhausted his strength, he threw the grenade into the thick fog.

However, he only weakly let go of his hand.

The iron-gray metal cylinder was loosened from his grip and rolled down the street with a loud thud, its fuse hissing and fume, rolling to the side of the road, and into a dry sink—through the darkness, into the crevices, through the sloping ventilation holes, into the time-worn underworld of the frost city-state, and with a roar in the forgotten darkness.

"Boom!"

There was a muffled sound far overhead, and the roof of the tunnel seemed to tremble slightly, spilling a little dust and dirt.

The "sailor" suddenly shrunk his neck, and his shriveled face showed a hint of nervousness: "This place really doesn't

Collapse?!"

"At least it hasn't collapsed in the last few decades," Lawrence stepped forward, the gas lamps embedded in the walls of the corridors on either side illuminating the path ahead, "As a dry corpse, why are you so daring? You're the kind of 'anomaly' that should be something that makes people fear, right?"

"I think······ The mere fact of digging such a huge underground space under the city-state is terrifying enough!" Anomaly 077's tone was nervous, "What do you guys think......

Lawrence shrugged, "I don't know, I didn't dig it."

Then he stopped paying attention to the dry corpse, but looked down at the small mirror on his chest and said, "Martha, how are you doing over there?"

"It's hilarious," Martha's voice came from the mirror, and there seemed to be distant explosions and artillery fire in the background, "After you entered the second waterway, the whole mirror world went crazy, and all the ships inside and outside a harbor were firing at me."

"Are you alright?"

"I'm not that easily sunk - but unfortunately, enemies don't seem to sink that easily, they're constantly replenishing from their reflections."

Lawrence was silent for a moment, looking up at the dark and deep hallway ahead.

"How far is it from here to the deepest part?" He asked.

"It's far away, but you can copy the short route" Lawrence frowned: "The short route?"

"Notice the water on the ground?

Find a street sign, then find the water closest to the street sign and see the reflection inside."

Puzzled, Lawrence followed Martha's instructions to a pool of water that met the requirements, and looked down at the reflection inside.

An intersection is reflected in the reflection, and a nameplate is nailed to the wall next to the intersection, and the words "Uptown Sewer Main" can be faintly seen.

His eyes widened and he looked up at his side.

On the wall next to him, the mottled nameplate reads "Port Area Sewage".

Martha's voice came through the mirror: "See? The world in the mirror is discontinuous."

「…… Incredible...... It's like a dream......" Lawrence muttered to himself, looking down at the pool of water beneath his feet again, even as one of the most experienced captains on the Infinite Seas, he had to admit that everything in this Mirror City was beyond his imagination, but he quickly came to his senses, "So how do we use these 'shortcuts,'"

"You've arrived," Martha said with a smile, "and you'll be there when you've been in this 'mirror' long enough."

Lawrence was stunned and hurriedly looked up.

In front of him was an intersection, with dim and flickering gas lamps embedded in the walls of the corridors at the intersection, and on one of his most recent nameplates, the mottled handwriting was faintly recognizable as a sewer main in the upper city.

Anomaly 077 looked at the suddenly changing environment around him in astonishment, his eyes quickly swept around the roadside nameplate and the reflection of the stagnant water, and it took a long time for him to suddenly shout, "Is this reasonable?!"

A circle of sailors all around them set their eyes on the dry corpse.

Lawrence didn't care about the "sailor's" reaction, he just looked thoughtfully at the dimly lit corridor in front of him, and after a long time he frowned suspiciously and said to Martha, "We're already on the second waterway, but what about the 'helper' you mentioned earlier?" What about the 'Queen's Guards, who are fighting on the second waterway?'

There was distant cannon fire in the mirror, and Martha's voice was delayed for a few seconds before reaching Lawrence: "Take the fork on the left, follow the red sign, and stop when there is no road...... They will appear, and when the time comes, they will appear."

Lawrence frowned, "Time?"

「····· The Queen's Guard attacks at midnight – midnight every day, and until that time they are invisible."

In the "Golden Flute" tavern, in the secret room where the underground liaison station is located, the "old ghost" lying on the bed suddenly opened his eyes.

"What time is it......

The old man's eyes seemed to be in a trance, as if he were muttering like a dream, but in the dimly lit room, the only thing that responded to him was the occasional "dropping" sound of some listening equipment, and the faint sound of gunfire coming from nowhere.

In the next second, the old ghost's eyes suddenly widened.

Faint gunshots?

Gunshot!

The old man woke up instantly, and the sound of the gunshot came to his ears, ethereal and vague, as if it was not only separated by the heavy walls and floors, but also by the passage of decades—he quickly got up from the bed, and then reached out and grabbed what was placed beside the bed.

It was a big wrench that he kept by his side even when he slept.

It's his tool, it's his weapon.

"It's on······ It's ······ I can't sleep here...... It's time to assemble......

The old ghost muttered, shudderingly put on his shoes, put on his coat on the chair beside him, and then looked up again at the room where he had just slept.

This was the secret room used to communicate with the Sea Mist Fleet, and Nemo arranged for him to rest here and take care of the equipment here.

But in the next second, the old ghost seemed to have forgotten everything related to this room, and his eyes became cloudy again, and he looked at the door not far away, puzzled.

"Oh! The door is here!"

The old ghost suddenly realized, and his face showed a happy expression, and then he walked over quickly, and opened the iron door that led to the secret passage underground.

Opposite the door was a narrow, cold hallway with flickering lights and hissing sounds from insufficient gas pipes.

"The gas pipes are not normal...... Isn't there enough air pressure...... No, no, now is not the time to care about this......" The old ghost looked at the light in the hallway, muttering quickly, he took a step forward, but as if suddenly remembered something, he looked back at the secret room where he had just rested.

The room was empty.

Everyone may have gathered in the tavern on the ground.

"Raven, I'm out, stay at home!"

The old ghost shouted into the empty room, then turned around, took his big wrench, which never left his side, and slowly walked down the deep and dark passage.

Walk towards the second waterway.

The time has come for the Queen's Guard to strike back.
