Beneath the well..
"Grell, Tell me the progress, is there any problem?"
A deep male voice came from one of the hooded person, he was the one that had a big muscular body, the two of them took off their robe and turns out that muscular man was Mortem, he was shirtless, and the other man beside him only wears basic outfit that is extremely common, with a lantern on his waist that give light to their surrounding, the only thing that might differentiate him between normal citizen is the dark cape that he wears on his back.
The caped man also seen to be holding a magic staff, he was a mage, and since Mortem was treating him nicely, that means that mage is an ally to him, just like Meritas.
Mortem is not someone that is willing to take anyone as his ally, if Mortem acknowledges that mage beside him, he must be strong, atleast on the same level as Meritas or higher.
"So far, it's going pretty smoothly, i've forwarded your order to that man, if he does his job well, i expect we'll see the result in a week" Said Grell.
After they arrived at the sewer, both of them seems to have taken off a ring from their index finger, the ring had a purple crystal embedded on it and once they've taken it off, a faint yet noticeable dark aura appeared all around their body, it happened for only a second, after that the aura disappears.
"You say you got this thing from your acquaintance? a ring with anti-detection spell in it, this would make things easier if this can be used infinitely– You should introduce me to your acquaintance later, Keukeukeuk.." Said Mortem.
"That's right, his name is Halm, hes a dark mage that specialize in dark magic, he had some similarities with you, so i think you will get along with him very easily— As with the ring usage, it can't be helped, afterall magic crystal don't have unlimited mana storage and even if you can refill it with your own mana, the spell inside of it will disappear"
Mortem laughed at Grell's word that he and Halm is similar to each other, he knew exactly what kind of person he is, a monster in a human form, someone that kills and torture for fun, his evil deeds have echoed throughout the kingdom, and yet here his ally said that there is someone that is similar to him.
"Interesting! Now i can't wait anymore, not with a possible gold that i can pick. Bring me to Halm tomorrow!"
"H- huh? W- wait a minute, tomorrow is a bit-
SWURRSSHH!!
Deep inside the sewer, a sound of waves was heard by Grell and Mortem, the suddenness startled both of them, and they were confused.
"What's that?" Said Mortem.
"Is there a flood?"
Thud!
Someone just fell into the sewer from the well above, Mortem and Grell isn't very far away from the location so they can see who is the person that just found their secret base.
"What now!?" They both shouted and looked at the circular light coming from above the ground.
In the middle of that, Sylias stood up from her initial crouched position after falling from above, she quickly saw Mortem and Grell standing next to each other not far away from them.
"Oh? So i was correct." She said.
Surprised with Sylias's sudden appearance, Mortem and Grell prepares for combat as their base have now been found out by someone else, but they didn't immediately attack, instead they stared at Sylias and analyzed everything about her, in less than 3 seconds, Mortem could tell that Sylias is not armed with any weapon.
"It seems like a rat has entered our sewer."
"Mortem, do you know her?"
"I'll ask this, who you people are?"
"—Huh?... Aha, i see." Mortem smirked.
He then lowered his stance and licked his lips, he thought that Sylias is just a weak demihuman who have accidentally stumbled upon this place by accident, seeing that she doesn't know him, that means she is not here to arrest or capture Mortem.
"You're really unlucky, to have fallen into this place without knowing anything"
Mortem didn't take any caution infront of Sylias, he purposefully lowered his guard, Grell beside him thought that Sylias might be not as much of a danger as he thought, after all, he had always been following Mortem's guts, listening to everything he said, and everytime he listened, their plan went on smoothly without encountering any problem.
'I managed to build this sewer is all thanks to him, if he hadn't told me about the guard's schedule and also the perfect time to build, we would've been found out by the guard because of noise complaints' He thought.
Grell was the one that built this sewer, his magic element is earth and that allows him to modify the ground to liking, and he could do this at a large scale, completing this underground sewer in just a few weeks through countless mana potion and also new technique to create bricks from nothing but dirt.
Back to Mortem, seeing Sylias for a few seconds made him realize that her body is not that bad, the thought of defiling and breaking that beautiful body made his heart race in excitement, he smiled deviously towards her.
"Do you want to go back? I can carry you to the top" Mortem said, his words full of deceit.
"That would be nice."
He then walked to Sylias that is just standing still with cold face, her eyes was locked to Mortem, but she didn't react at all seeing his massive body and lustful face, however her tail swayed a few times.
'I wonder what kind of face this girl will make when i cut her tail and ears off one by one with a knife and then tore that beautiful skin from her face.. Ahh, once i got you in my hands, i will never let you go.'
Eventually, Mortem was close enough for him to touch Sylias's shoulder, he planned to punch her in the face once his hand touched her shoulder, but after he placed his palm on Sylias's shoulder, he immeditely got a feeling that punching her right now would be a fatal mistake, one that could cost him his life at this very instant.
His heartbeat quickly changed from beating fast because of excitement to life and death danger, Mortem's eyes shrinked after he accidentally looked at Sylias in her eyes, that slit pupil along with the bright red glows coming from her eyes felt like a sharp needle piercing through his vision.
'W- What— What is this– My guts are telling me that this girl is dangerous'
From the distance, Grell saw Mortem's body froze after his hand touched Sylias's shoulder, at that moment he initially thought that Mortem is just thinking about how he would play or torture her, like he usually do to his victim, but unbeknownst to him, it was something that even Grell couldn't expect.
'M- my body.. I- I cant move my body!!' Mortem thought while panicking.
"I was thinking why you're not attacking yet, but it seems like you have somekind of a plan in your mind, if that's the case.."
Sylias released a small portion of her aura, even if it was just a small portion, it is still unbelievably powerful that Grell immediately kneeled.
SWOOSH!
'ARRKHH.. TH– this pressure.. So strong!! I- i can't move.. S- shit i feel like my bones is going to break!'
Mortem on the other hand held up against the pressure, a small crack formed beneath his legs and if Sylias didn't stop her aura, the ground would shatter.
Mortem finally escapes from the pressure and as soon as he was able to move his body again, he clenched his fist.
'Huff.. HUFF– I NEED TO KILL HER NOW!'
< GREATER STRENGTH BOOST >
Against all odds, even though his body is trembling, Mortem uses his sword aura on his fist, enhancing his power by multiple times, with one attack, he gives his all and launched a single punch towards Sylias's face as fast and as strong as he could.
'HE'S GOING TO DESTROY EVERYTHING!' Grell screamed in his mind.
He thought that there will be a big explosion and this whole sewer would get destroyed along with the houses above the ground, but when he closes his eyes and was bracing for the impact, there was no explosion, the sewer is still intact.
SLASH!
'H- huh!?..'
He heard something being slashed, but remembers that Mortem didn't have a sword with him, Sylias also have nothing to be called a weapon.
Curious to see what happened, Grell opened his eyes and then looked towards Mortem's direction, hoping to see that he had somehow killed Sylias.
However, his expectation was shattered into small pieces, his worst nightmare came true, He hoped it would be Sylias, but Grell instead saw Mortem lying motionlessly on the ground, with one thing missing, and that is his head.
Sylias's hand was soaked in blood, her clothes are also stained, the smell of blood is lingering all around her body and she have this menacing look on her face.
"Ah- ah.. UAAAAGHHHHHH!!!"
Grell cries out of fear, he sees Sylias walking slowly to him, she then crouched infront of him.
"Goodnight."
That was the last thing Grell heard.
SLASH!
***
A minute pass by, Sylias is still on the same location when he killed Mortem and Grell, she was thinking about what her next step should be.
'Is this guy the leader?' She thought.
Thinking back about her fight with Mortem earlier, Sylias confessed that at that time she didn't even know if she could use aura like that, when Mortem touched her shoulder, Sylias initially felt a bit grossed by it.
'His face when he approached me, that's something you'd only see in horror movies about psychopathic serial killers— at that time, i thought about punching him, but i don't want to turn this sewer into dusts, so i thought about other ways, thats when i remembered about aura.'
'Just like when i held the Abyssal Monolith Staff back then, i could see its aura flowing out and filled the room with pressure– I imagined that i would be able to spew out some aura too, so i imagined my aura flowing out of my body like a river, and surprisingly it was easier than i thought, and im glad i only released a bit of my aura, because i knew it would've destroyed everything if i had released all of it..'
Just then, Sylias heard a sound coming from infront of her, it sounded like an explosion and also a few of sword swings, it must mean that there is a fight going on deep in the sewer.
'There's still other people here? now i have a reason to go deeper'
When Sylias was about to walk deeper into the sewer, she first told the mysterious person hiding in the other side of the sewer to come out.
"Hiding in the darkness, i wonder where did you come from."
It was Captain Jade, in the flesh, alive and scared.
