The fairy maid cheers for her deceased master today.

The time to depart arrived quickly.

The rain outside continued incessantly, like an invisible gray veil shrouding the vast city.

"Are you ready?" Ex turned around, his gaze sweeping over the two people in the living room.

Elena was nervously adjusting the collar of her dark green coat and putting on gloves.

Despite her nervousness, her eyes were unusually firm, like burning emerald flames.

Angel, fully armed, had a face full of tension and excitement as she tightly clutched a specially made kerosene lamp—a "flash kerosene lamp" that Ax had rushed to make long ago, with a brass body and a flashing combustion block hidden inside.

Based on the experimental results, this kerosene lamp is most effective against Swamp Xenomorphs and can also effectively counter Spring-Heeled Jack.

Therefore, X strongly suspects that Spring-Heeled Jack is actually a Swamp Xenomorph. It's just that his evolutionary level is too high, and he no longer appears to have the characteristics of a Swamp Xenomorph.

"Ready, Master!" Angel's voice was clear and loud.

Irene took a deep breath and nodded: "Yes, I'm ready too."

Ax didn't say anything more. He simply tucked the blood-stained letter into his pocket, clipped the kerosene lamp from Angel's hand to his waist, and then walked out of the detective agency first.

The rain, carried by the wind, lashed his face as always, cold and damp. He habitually pulled up his coat collar, then waved for a carriage.

"To the old quarry east of Greenwich Park," Axe said to the driver.

The coachman was an old man with a wrinkled face. He looked at the three of them, especially at Elena and Angel, the two beautiful fairy girls. A hint of surprise flashed in his eyes, but he still nodded.

"Very well, Sir. However, I must warn you, that place... is not safe."

"We know," Ax said calmly, handing him a silver coin. "Please hurry. Keep the change."

Silver coins come in many denominations. But this time, Ax gave us a silver coin worth a full crown.

The normal fare is 1 shilling for the first 2 miles, and an additional 6 pence for each mile beyond 2 miles. This silver coin would be enough to travel 7 miles, or more than 10 kilometers.

The coachman took the silver coin, his eyes lit up, and he let the passenger into the carriage. Then he immediately cracked his whip, and the carriage sped off down the wet street.

The carriage traveled through the streets of London, gradually shifting from the bustling West End to the desolate East End. It had moved from the inner city to the outer city. The buildings lining the streets had changed from elegant townhouses to dilapidated factories and warehouses.

The air was filled with the pungent smell of the sea and industrial waste, mixed with the dampness of the rain, creating an unpleasant and complex odor.

The carriage then left central London and headed southeast along the Thames. The rain gradually subsided, but the sky remained overcast. The carriage bumped along the muddy road and finally came to a stop in front of a desolate hillside.

"This is it, sir." The coachman stopped the carriage and pointed ahead. "The old quarry east of Greenwich Park. However, I advise you not to go near it; there are... bad things there."

Ax had already paid the fare, so he thanked the driver for the reminder and let him go.

He stood on the hillside, looking down at the old quarry below.

It was a vast depression, as if the earth had been torn open with an ugly scar. The exposed rocks were grayish-brown, covered with moss and dark green vines.

The abandoned mine shafts stood like gaping black maws, silently open. A deathly silence permeated the entire quarry, broken only by the sound of raindrops falling on the rocks and the occasional, faint sound of wind emanating from the depths of the mine.

"We have to be careful," X said in a low voice, pulling a brass telescope from his pocket.

He obtained this yesterday while everyone was asleep, through an exchange using tools from the basement.

Products offered through equivalent exchange are guaranteed to be of high quality. The lens is crafted from brass, and the crystal-clear lenses allow for a clear view of distant objects.

Axe raised his binoculars and carefully observed the situation at the quarry.

The details of the quarry were magnified in the telescope's field of view.

Abandoned mine entrances are scattered throughout the quarry, resembling gaping black mouths. Scattered on the ground are abandoned mine carts and rusted rails, covered in a thick layer of rust and moss. Some tenacious plants grow in the crevices of the rocks, but most are dark green moss and ferns, adding to the desolate atmosphere.

Although desolate, it is full of life, and it is hard to believe that this is a place where alien species roam.

After all, fixed mindsets still exist... People always feel that where alien species appear, nothing should grow.

Ex's gaze swept across every corner of the quarry, and finally, he saw the "bad things".

In several locations within the quarry, on relatively open areas, swamp aliens roamed.

They come in various shapes, but all are a nauseating black, as if they were a mixture of rotting mud and decaying plants.

Of course, the plant parts are just for decoration, as if they have just been swallowed up.

There are no humanoid aliens here. But some aliens are like giant worms, their bodies covered with black slime and bubbles; others are like deformed spiders, with black slime constantly dripping from their bodies, forming puddles of black liquid on the ground.

It is clearly a swamp alien species that may have been created from local organisms that were thoroughly polluted.

These swamp creatures seemed unaware of X and his companions, simply wandering aimlessly through the quarry. Their movements were slow and clumsy.

Of course, X now knows that these alien species become extremely dangerous and manic when provoked, and their speed also increases.

"I see them..." Ex put down his binoculars. "There are five swamp mutated creatures in total. One is in the central open area, two are at the mine entrance on the left, one is at the mine entrance on the right, and one is near the abandoned minecart in the back."

Elena and Angel also joined in, observing the swamp creatures through their binoculars. Angel pursed her lips tightly, her small hands clenched into fists.

"What should we do?" Elena asked.

X pondered for a moment, then said, "The other side hid the letter in this unsafe place; we can't force our way in. Since the alien species is dangerous, we'll eliminate the danger first. We must take them down one by one."

He pointed to the largest swamp monster in the center of the quarry.

"That one is the biggest, the most conspicuous, and the most dangerous. And it's far away from the other alien species."

"Let's deal with it first. Elena, use your vines to restrain it. Angel, attack its eyes with ice flowers. Once it's restrained and unable to move, I'll aim a few silver bullets at it."

Elena and Angel both nodded in understanding.

The action begins!

Once they confirmed that there were no other mutants around, the group immediately surrounded the large, beetle-like swamp mutant.

Irene took a deep breath, then stretched out her hands, her fingertips glowing green. "Act One, The Vine Cage!"

As she spoke, several thick vines shot out from the ground, like giant green pythons, and quickly coiled around the swamp monster. The vines bound its body, rendering it unable to move.

The alien species began to struggle, and black mud gushed out from its body, scorching the vines with a sizzling sound.

"Now!" X shouted.

Angel immediately raised her hands, her fingertips glowing with a blue light. "Ice Flower!"

Several crystal-clear ice flowers flew from her fingertips, striking the swamp monster's eyes with pinpoint accuracy. The ice flowers exploded on its eyes with a crisp sound, splattering black slime everywhere.

The swamp creature appeared unharmed. However, the frost marks on its body indicated that its movements were further restricted.

The swamp creature let out a hiss and struggled violently, and it was clear that the vines were about to lose their grip on it.

Ex let out a sigh of relief.

One advantage of the biological form of the swamp alien is that its weaknesses are more obvious.

He immediately aimed at the alien's head.

One shot, and it's dead.

"Awooo—!"

The swamp monster let out a painful screech, and black smoke began to rise from its body, like ice and snow scorched by the blazing sun.

One more shot.

Another one.

He fired three shots in quick succession.

The vines tightened their grip, and the swamp creature's body gradually disintegrated under the combined effect of the three silver bullets and the vines, eventually turning into a pool of black slime that dissipated into the earth.

"It's solved!" Angel cheered.

"Don't get too excited," Ax said calmly. "There are still four. And their attention may have already been drawn to us."

Sure enough, the other four swamp creatures turned to them, emitting low hisses, and began to approach them.

"Let's split up," Ex said quickly. "Elena, use your vines to hold off the two at the left mine entrance. Angel, use your ice flowers to attack the one at the right mine entrance. I'll take care of the last one."

To contain and defeat them one by one.

Elena and Angel sprang into action. Elena used her vine magic again, entangled the two swamp monsters at the left mine entrance. Angel attacked and blocked the one at the right mine entrance with ice flowers. X raised his revolver and aimed at the swamp monster near the abandoned minecart.

"Bang!"

The silver bullet pierced the swamp monster's head, splattering black slime everywhere. The swamp monster staggered a few steps but did not fall. It let out an angry hiss and then charged towards X like a black cannonball.

"Bang!"

Then he collapsed.

That's why it's called so fierce.

X then reloaded to support the others.

Soon, the three swamp monsters also disintegrated.

"Great! We've got it done!" Angel was a little excited.

Ex, however, remained vigilant. He observed the quarry again. Although the swamp monsters had been dealt with, an eerie atmosphere still lingered in the quarry.

The abandoned mine entrances resembled giant black mouths, as if waiting for something.

"It seems... we need to go deeper into the quarry," Ex said. "This matter is definitely not that simple."
