The Invincible Full-Moon System

The chirping of birds can be heard, disturbing the peace of the sleeping eyes.

Slowly the eyelids trembled before opening to only see the dilapidated ceiling that of an aged hospital, the scent of steel and drugs also greets the nose and forces an uncomfortable expression to appear on the face.

Rex woke up from the bed and instantly feel uncomfortable with the place he was in.

'I really hate being inside or near hospitals, the scent makes me sick...'

Looking to his front he saw Evelyn and Gistella still lying on the hospital beds, their calm breaths show that they were already healed from the injuries they suffered and it was just a matter of time before they finally regain their consciousness.

Scanning the room, Rex didn't find Flunra and Adhara anywhere.

Flunra is probably sleeping outside of the hospital, on the cobblestones since he was not a human once but Adhara on the other hand seems to haven't come back yet after she left abruptly last night.

But she's near, Rex can sense her. She should come back when the Teleportation formation is done.

Rex rubs his neck feeling the dryness invading his throat, he intends to go out and get a drink for himself but his hand shifts to his chest out of a sudden. It was the crippling pain that annexed his heart making breathing very heavy.

'What's this...? Why am I feeling this much anxiety and uneasiness?'

It hits him instantly after he wakes up, and he has never felt this much uneasiness suddenly appears.

Not only does his chest was drowned in this sudden feeling but his head started to feel light-headed, and even his breath started shortening almost as if he had a heart attack. Rex tries to hold on to the sofa's handle but his body slipped and falls to the cold floor.

'System, what is happening to me?', Rex was forced to ask, this is not normal.

<Scanning the user's body...>

<Completed!>

<All of the bodily functions are normal, mana functions are normal, bloodline functions are normal, and King Mark's functions are normal. The user is in perfect health without any anomaly happening>

Reading the system's notifications, Rex finds it weird since clearly, something is wrong.

'I- I need to take some fresh air...'

Forcing his body to stand up while using the sofa's handle as support, Rex slowly stood up under the crippling feeling before he grabs the door handle and yank it wide open. Even though he didn't mean it, the door even slammed into the wall because of that.

Walking through the hospital's hallway while holding by the wall, Rex made his way to the lobby.

Many people are looking at him weirdly because of the cold sweat flowing down his forehead, his weak eyes, and the way he was walking unstably. Some of the nurses even asked if he needed any help, but he just waves his hand and made his way out of the hospital.

Upon reaching outside, Rex inhales a deep fresh breath but it was not working.

In fact, he was feeling the crippling sensation even more.

Rex is a Werewolf, an Exalted Royal Black Prince nonetheless so he's basically immune to sickness aside from the full brunt of silver exposition and also the White Omicron. Something like dizziness and migraine should've been repelled by his bloodline.

But this time it was not the case, he stumbles and falls down the stairs.

"Argh..."

Contrary to the inside of the hospital which is crowded with people that are either sick or visiting, the front yard of the hospital for some reason is empty. Nobody was around, only a single road in between grass fields leading to the entrance can be seen.

Grabbing the center of his chest with both hands, Rex's eyes opened wide in confusion.

'Just what is this? Is this somekind of warning from the next full moon? But it's sunny, the sun is up so that's not possible', Rex thought, gritting his teeth to suppress the crippling feeling that shuts down his entire body.

While lying face-first on the ground, Rex slowly raises his gaze to stand up.

But the pained mixed with confusion expression he was wearing was replaced with a surprised one when he finds something appeared at the entrance, it was so unbelievable that Rex needed to rub his eyes before looking at the entrance once more.

'A Wolf...?'

Standing just by the entrance is a wolf that is the size of a regular wolf before the mutation.

Unlike the monstrous creatures that he has battled throughout his life, this wolf brought a pleasant feeling, especially the earthy brown furs that swayed from the wind elegantly. Its eyes are also the same matching color contrast, glowing copper that is ambient and beautiful.

It just stands there looking at Rex with its copper eyes.

Although there are forests around the city he was in, there should be no animals mutated or not that are able to get inside without alerting the city guards guarding the place. Rex finds it weird for this wolf to be able to reach here.

But momentarily, the crippling feeling disappears, swept away by the warmth of the copper eyes.

Now that his body recovered from the crippling sensation and regains its senses again, there's a link of familiarity that he felt from the brown wolf. A feeling that made him feel close to the wolf.

Rex was about to ask who the wolf is but stopped when he saw the wolf suddenly smile.

The corners of the wolf's mouth quirk up into a warm smile before it points its muzzle upwards, a long howl then resounded filling and covering the entire hospital and beyond. It was surprising for Rex to find that nobody heard this melodious howl that sounded like a beautiful tune.

Aooouuu~

Just as the howl keeps on going, the wolf's body slowly fades, turning into brown energy.

Even though it was a wolf that he has never seen before, Rex feels sad from seeing the wolf turning into brown energy before being blown away by the wind. At the moment before the wolf completely fades, the wolf gives Rex a smile again.

Particles of brown energy from the wolf then flew up to the sky beautifully.

Rex watches this happening with gloomy eyes before out of nowhere, a soft whisper brought by the wind penetrates his ears which made his entire body stiff like a statue. It was the voice that he knew very clearly.

"Forgive them"

"I've always loved you until the very end..."

Slowly his eyes started widening in the realization of the departing voice, "M-Mother...?"

After the last strand of the brown energy vanishes in the sunny sky, another voice enters his ears and it belongs to someone he knew. But this voice was calling out to him as his body rocked left and right.

"Rex!"

"Rex! Get back to your senses!"

Under the calling voice, Rex blinks his eyes a couple of times before everything changed.

The front yard of the hospital which was desolate of people becomes crowded with people walking in and out of the entrance, he was kneeling in the middle of the road facing the entrance under the onlookers' concerned gazes.

Flunra was the one shaking his body, trying to make Rex snap from whatever he was seeing.

"W-What happened?", Rex asked in confusion.

Hearing this Flunra straightens his back with a sigh, he then shakes his head and explained, "I was sleeping and woke up when I hear a commotion, I wanted to check on you but then I saw you kneeling in the middle of the road while other humans are trying to help you. I tried calling on you for a while but you didn't respond, I thought you were attacked by a mind or soul spell"

Remembering the blank gaze, Flunra sighs in relief knowing that Rex is fine.

At first, he was about to try and check if he was attacked by any mind or soul spells. It's going to be easy checking if there's any mind spell cast on him but checking the soul spell would be very dangerous.

Flunra is glad that he didn't need to resort to that or Rex would need time to recover.

With the destruction of the Vampire Stronghold, it was not the time to be injured and bedridden.

But then again aside from his suspicion that Rex is probably still in a trance after killing Ruston, he finds it hard for anyone to be able to influence his mind now that Rex has King Mark and reached the ninth-rank realm.

Only a Witch and very powerful figures of the same rank can do that which is unlikely.

None of them has that kind of spell that works from this far, even back during the Radical Era the Queen of Vampires, Elizabeth has the deadliest mind and soul spells but they require to look at the target's eyes.

In short, it's impossible for Rex to be attacked by mind and soul spells in this current time.

Rex nodded his head finding what he experienced was a mystery to himself, but the sensation has disappeared and he now can stand up properly. But that mystery didn't last long as a notification appeared in his vision.

<New Blood Moon Quest - Absolute Devotion>

Sacrificial Count: 1/2

Looking at the notification, he was confused but curious at first, forgetting the quest's existence.

'New Blood Moon Quest? What was the quest about again... I think it's about the Blood Moon King Mark, I got it after my rampage in the Delarosa Family's territory. And as for the completion requirement...'

As soon as his eyes landed on the Sacrificial Count, his breath suddenly got cut short.

Everything started spinning and his breath resumes but it becomes heavier, it was due to the number 1 etched clearly beside the Sacrificial Count that indicates one thing which made Rex looks down with a grim dark expression.

Unconsciously, his auras started to leak which surprised Flunra on the side.

With the regular people in the surrounding, even a glimpse of Rex's King Mark would crush them under the sheer amount of force. It's going to be a catastrophe but Flunra was confused as to why the sudden anger.

"Rex? Your aura is leaking, and there are normal humans here"

Instead of answering, Rex kept silent as his body slowly start to tremble uncontrollably.

Flunra saw Rex was not listening and even both of his fists were clenched strongly and trembling, he can feel the rising anger inside of Rex from the link between Beta and Alpha between them, 'This anger... it's way stronger than the ones he had with Ruston!'

Just like cutting the already loose rope, Rex's aura exploded upon seeing another notification.

<Sacrificial Count: 2/2>

<New Blood Moon Quest - Absolute Devotion has been completed!>

<Kaiser of the Scarlet Garland is pleased, the user has earned the trust of the Blood Moon!>

KABOOM!!

"What in the Origin's name happened to you?! You killed all of them!", Flunra exclaimed in absolute terror as the King Mark on Rex's forehead was activated and glowing with an endless amount of crushing energy.

Even that small spark alone decimated the entire hospital and beyond.

People that are inside the hospital and even within a mile radius from where Rex stood got killed instantly just from feeling the rampaging kingly energy, they all got crushed into the ground, flattening their torsos until there was nothing left.

Blood instantly filled the entire place from the absolute suppressing force from Rex.

In fact, the crushing force was so strong that the people around them that got crushed by the aura burst and even start a rain of blood that stains the green grass with a stark color of thick liquid red.

Hundreds of notifications swarmed Rex's vision from the death of the people in his surroundings.

The sky-high aura exploded once again pushing Flunra back all the way before crashing into a couple of wooden houses, its crushing force expanded and makes the destruction increase even more which made screams of terror fill the entire city.

What was filled with buildings was now flattened, even Flunra can still see Rex from the distance.

None of the houses or other buildings were spared.

'Where did this anger come from?! It's still mounting even higher! At this rate, he's going to destroy the entire city and went on a rampage!', Flunra exclaimed while protecting his head from the gust of kingly energy that is still pushing him back.

Knowing that something is wrong, Flunra carve a rune on his palm quickly before he dashed.

Adhara also came back quickly and arrived in half a minute just to see Rex standing in the middle of rubbles, she was absolutely terrified in the picture she was seeing right now that was covered in blood, corpses, and gore.

Out of everything they've been through, Rex has never injured any normal person.

But now he decimated the entire place which should definitely indicate that something is wrong, and Rex didn't even bother with the destruction he caused as his eyes trains forward into the void with his King Mark glowing brightly on his forehead. Fully exposing himself for anyone to see.

With blazing claws, he tears the dimensional fabric and opens a portal for himself.

Flunra that saw Rex was about to leave puts more power into his dash, he reaches out his hand and just barely manages to engrave the rune he draws on Rex's back just before he enters the black portal and disappears.

After he left, the air becomes still again as the kingly energy vanished.

Sprinting from the side, Adhara ran toward Flunra that stumbled and rolls across the rubbles and blood. She stopped right beside Flunra who is getting up before she looks around once more at the destruction Rex caused.

It made her suck in a cold breath still feeling this is all surreal.

"What happened..."

Upon hearing this, Flunra stood up and also looks at the destruction, "I don't know..."
