The Invincible Full-Moon System

<Sudden Quest!>

Receiving the news of an imminent Rastrikan Demon attack on the Dwarf Kingdom, one of the user’s vassals, the user must stop their plans and ensure they don’t succeed. Much like the pack members, the user bears the responsibility for protecting them. Invincibility signifies being impervious to defeat across all endeavors, not only individual prowess.

Time Limit: 3 Days

Quest Reward: 200 Billion Exp, Rastrikan Demon Core per demons killed, Sin of Wrath Rune, and Sin of Envy Rune.

Learning of the attack, a sudden quest was triggered.

Rex reads through the quest that beckons him to stop the Rastrikan Demon’s attack and couldn’t help but smirk a little, the quest reward that he would gain from completing the quest intrigued him greatly.

Sin of Wrath and Envy Runes would be the prize of this sudden quest.

Albeit not knowing what would these two runes represent, the hope that this rune would grant the power of both sins to the branded target is a delightful thought. For instance, if the Sin of Envy rune was branded to Adhara, her elemental prowess will skyrocket.

It’s also worth mentioning the Rastrikan Demon Core that he would gain.

Back when he was still fighting the Demons in Beah City, he was rewarded Demon Cores from the System which gave him quite a boost in physical stats. A very great reward during that stage of his journey.

Now he couldn’t help but wonder how much the Rastrikan Demon Core would grant him.

Moreover, if he killed enough Rastrikan Demons, he could distribute it to the core players of his forces. Lady Lauren, Daniel, Ugrok, and the others would certainly be benefitted by this the most.

‘A perfect quest, I’ll need to make sure to kill lots of them’ Rex thought evilly.

Even though the System told him to only stop their attack, he wouldn’t exactly only do that.

Having permission from Elder Tilrith, he wouldn’t hesitate.

Rex would plan on wiping the entire Rastrikan Demon if he could, and that would bolster the demon cores that he would gain which would eventually lead to his forces becoming stronger than ever.

If such an opportunity appeared, hesitating would be foolish of him.

Striding onward to the throne with a pondering evil smile on his face, Adhara followed from behind as she hasn’t gained a clear answer from him. If he’s on board, then she would notify the Dwarf King about this.

“If you say so, then okay… We’ll take care of the Rastrikan Demons” Rex mused dominantly.

Upon hearing this, Adhara’s eyes flash.

Since Rex has decided to take care of the Rastrikan Demons, she then explained what she has learned from the Dwarf King. It was insightful, knowing the fact that the Rastrikan Demons have a fearsome reputation as well as the fact the Dwarves and Elves have no elders.

Nevertheless, a fearsome reputation gave no surprises.

In addition, everything started to become clearer now with this new information.

Rex finds it natural for the Dwarves and the Elves which also include the Dark Elves decided to join him rather easily, the fact that they have no elders means they were going to be susceptible to a dangerous situation during the World Awakening.

‘But that doesn’t matter, I also need their numbers’ 

Despite being used as a shelter by those races, he doesn’t seem to mind it at all.

“Dwarf King and Queen Shanaela have already assessed the Rastrikan Demons to be at their peak strength during the First Breath, given their focus on physical attributes within the Demon Race. I think we should fortify our defenses and counter them with ranged attacks” Adhara propose, outlining a battle strategy.

However, she saw Rex’s lips curled into a peculiar smile in return.

Perhaps Adhara remains cautious, with a primary concern for safety, leading her to adopt a conservative approach. But Rex has a different perspective, he sees an opportunity in the formidable reputation of the Rastrikan Demons that he can exploit.

“If we play it like that, we’ll be playing in their field of expertise” Rex replied and leans back.

Upon hearing this, Adhara frowned but soon realized what he meant.

Gesturing expressively with his hands, Rex then continues, “Considering the Rastrikan Demons’ usurping and sadistic nature, as you’ve described earlier, letting them take the initiative to attack will only be a disadvantage for us as they excel in precisely that”

“So you’re saying that we should be the one attacking them?” Adhara asked to make sure.

Rex nodded his head firmly, his eyes shimmering with sharpness.

Oftentimes, a reputable enemy is easier to predict than a completely unknown enemy.

An army that is entirely focused on attacking others all their lives would have that attitude ingrained inside their blood deeply that when it comes to defending, they would adopt the same attitude which would become their downfall.

If it’s as predicted, then Rex’s forces already won before the battle even started.

“For now, we need to know their location. Go and tell the Dwarves and Elves to send scouting parties to search for them.  I predicted the Rastrikan Demons are two to three days away, so make sure to find them before then” Rex commanded with an authoritative tone.

Upon hearing this, Adhara bowed slightly in affirmation.

Instead of leaving at once to do as she was told, Adhara didn’t move from her spot. She steals glances at Rex a couple of times, it seems she has something more to say. But she was rather hesitant to say it.

“If you have something to say, then say it, Adhara” Rex said, slightly confused.

Adhara would normally say what she has on her mind, so it’s weird seeing her like this. Pausing briefly, she then takes a deep breath before she replied with a subtle tone, “I was told by Evelyn about you…”

“Hmm…?” Rex’s brows furrowed in confusion, but he instantly realized what she meant.

Just before Adhara could continue what she was saying, he already raised his hand and intervenes, “I know what you are about to say but it’s better that I bear the beatings. I have many methods to survive, and you do not, so there’s no point in asking me to give room and not worry about you”

“What…?” Adhara mused in confusion. ‘I was not going to say that though’

Finding that she was confused by his answer, Rex tilts his head.

But this made Adhara quickly reply with a wry smile on her face, “Y- Yes… I’ll be careful from now on. Going inside the Emham Forest knowing that the Executor is near it is reckless of me, I won’t do it again”

Upon hearing this, Rex nodded his head, he was relieved the two realized their mistake.

Adhara then suddenly asked, “Say…  C- Can I offer this task to someone else?”

“Not that I don’t want to do it or anything like that, but it’s just that… I haven’t gotten the time to be with you after you wake up, and you know I’m also worried about you” Adhara quickly corrected, she seems to yearn for being with him for a bit.

In a way, it’s quite understandable for her to be like this.

Since Rex has been unconscious for days, she hasn’t had the time to meet with him. And when he regained back his consciousness, she was also away dealing with the problem with the other allied forces.

Obviously, that would frustrate her more than a little bit.

Rex looks at her whilst sitting on the throne leisurely for a couple of seconds, he then squinted his eyes, feeling dubious whether this thought was purely from herself or not.

Knowing the situation right now, it’s unlike her to be acting like this.

But then again, she might sense that Evelyn is getting closer to him so this happens.

If he gauged Adhara’s jealous personality, that would definitely trouble her. However, for some reason, Rex feels like she was influenced to say this more than her own jealousy, there’s anger inside of her too.

Due to that, he decided to take a wild guess, “Did Elder Tilrith say something to you?”

Upon hearing this, Adhara widened his eyes.

“Y- Yes…”

She decided to be truthful albeit a little embarrassing for her to say, it was even more embarrassing when Rex seems to read her like an open book. But she can’t lie that what Elder Tilrith said didn’t bother her.

Rex sighs when he heard this, “I don’t think it’s time for something like that, Adhara…”𝒪𝑽𝐥xt.𝑐𝗈𝔪

“If we dealt with the Rastrikan Demons already, maybe we could spend more time together.  But for now, can I ask you to focus on the task at hand? I still need you to perform as the Female Alpha” He added, deciding that this would have to wait.

Adhara pinched her own hand when she heard this.

For some reason, she feels a burn in her chest but she eventually nodded her head.

“Then, I’ll take my leave…”

“Okay, convey my message. Tomorrow, I’m going to be there”

Upon her figure disappearing from the throne room, Rex could only sigh lightly before he stood up and heads back to an empty room where he would not be disturbed. It’s time for him to absorb the cursed energy from the Jar of Malice.

He would need to hurry up even more now that tomorrow he would need to leave.

Dealing with the Rastrikan Demons would definitely need his personal help, and he also needs to be there so that he could exploit their fearsome reputation. It would make his presence more prominent in the Supernatural world.

Sitting in a meditative position, he then summoned the Jar of Malice.

Putting it in front of him, he then instructed the System to make it easier to keep track.

‘System, calculate the cursed energy inside the Jar of Malice and made it into absorption percentage so I could keep track of how much is inside left. I need to finish absorbing it by night’

<Affirmative, calculating the cursed energy…>

Meanwhile, somewhere inside the Supernatural territory.

A group of teen-sized humanoid creatures with translucent wings that were similar to that of butterflies could be seen fleeing in fright, their expressions were completely pale as they occasionally looked back in crisis of the impending horror.

Some of them have lost their limbs, creating a trail of blood on the ground.

Just one look of their fair skin and ageless face, eternally youthful is enough to tell that these humanoid creatures were fairies. Dark fairies to be exact, those that hide from the sun and only come out at night.

Growl!

Out of nowhere, gruesome laughter, a cacophony of wicked mirth resonates from the back.

Upon hearing this laughter makes these fairies’ hearts tightened with dread, they were absolutely terrified as they remembered the merciless onslaught their small city was susceptible to earlier that came suddenly.

But out of nowhere, three fairies got struck by razor-sharp claws.

“Kyaarggh!”

Each of the three fairies yelped in pain having their flesh and bone torn completely.

A crimson spray of fresh blood came out of their severed limbs, and their hope of surviving sank into oblivion at the sight of wicked grins etched upon the visages of a demonic creature that has already set its eyes on its poor victims.

“Wait! I’m a civilian! I swore to my Origin of no bloodshed!”

“Spare us! We are not a part of this!”

Most of the fairies pleaded, knowing that outrunning this demon was nothing but futile.

Competing in physical attributes against this monstrous demon that originates from the most vicious part of hell is foolish. However, these fairies didn’t realize that begging for their lives for the demons is even more foolish.

Not a hint of mercy could be seen in its red seething eyes that know only malice and gore.

In the face of such a monster, the fairies burst into tears.

“Relish the taste of despair… Beg me more! Cry more! Scream more! Your pain, our pleasure!”

Sparing not one of them, civilians that were incapable of defending themselves due to their promise to the Origin, the demon started mauling the fairies with sadistic laughter. A spark of intoxication could be seen in its eyes.

Almost as if the blood of its victims acted like wine that made the demon go crazy.
