The Invincible Full-Moon System

Inside the tower, Ana is currently sitting in her bed-chamber while looking at the glass in front of her absent-mindedly. The glass is still full of blood, she hasn't touched her drink at all.

Ana is sitting on a chair with a couple of scrolls on the table that hasn't been opened yet.

Her white curly hair falls down to her front as she leans her head on her hand, her other hand which is decorated with black fingernails reaches for her neck before she hisses in pain. The wound on her neck still pains her even though it's noticeably better.

Slowly her hand reaches for the drink before she drinks it carefully.

Psshh...

"Rrghh...", Ana grunted feeling the blood that flows down her throat burns her neck, the wound he received is very inconvenient located on her neck.

Only the burning sound and the sound of her drinking can be heard inside the bed-chamber.

Inside the bed-chamber is not luxurious like what the humans had in the current times, maybe if this bed-chamber is in the early millennia then it can be considered luxurious. The size of the master bed is very big taking a huge chunk of the bed-chamber and also covered with wrapped veils.

There's a treasure chest just on the foot of the bed, a couple of furniture such as cabinets, tables, and chairs. Golden ornaments that bring the luxury taste to the bed-chamber and also a big open window beside the bed.

Ana is facing the wall with the bed on her back, she seems to be tired laying her head on the table. But her eyes soon glisten feeling a cold wind brushing on her back.

With a slow movement, Ana raises her head from the table and straightens her posture.

Her eyes glow with a red hue while looking straight at the black stone wall in front of her, she then glances to the side without turning back before she mutters, "I didn't expect your visit, you highness"

On her back is a man standing in the window while looking at her silently.

The presence of this man makes Ana gulps harshly disregarding the pain in her neck, it's like a devil looking at her from the back. But the devil bore evilness to anyone, unlike this man that seems to bore violence, hatred, and anger to her specifically.

Rex stands in the open window while looking at Ana.

He doesn't answer for a good ten to fifteen seconds turning the silence inside the bed-chamber into deadly silent, the tension inside the room reaches its peak.

"I believe you have someone that belongs to me...", Rex mutters with his red glowing eyes.

Ana carefully stands up from the chair before turning back to face Rex, she now realized the disparity between their strength upon looking at Rex directly. His body seems to contain destructive energy that can explode at any moment.

It's like standing in the presence of King Solomon, the air chokes her.

The worry and scared expression she once saw on him is nowhere to be seen, his face is only plastered by a cold brutal look gazing at her like she's food. Like a cold-blooded beast that hasn't found a meal in years.

Even standing in front of Rex brought a huge amount of pressure onto her body.

Mythical Aura is leaking out of Rex's body showing Ana that he's a Prince of Werewolf, the Silver Eye in his right arm is also emitting energy that puts Ana's senses on alert. Supernatural Slayer, she can feel the power of the Silver Eye.

"She belongs to the Vampires the moment she's bo Ana replied.

But just as she blinks, Rex suddenly already standing in front of her towering over her easily. His dagger-like eyes are staring at Ana full of killing intent, "I'm not playing games, Ana. Where...Is...Rosie?", he said emphasizing his question.

The meek and submissive aura coming from Ana is way off the mark since the last time Rex saw her, he became so strong since the last time they met.

"Don't worry, I'll tell you where she is", Ana replied calmly, in fact, too calm.

Seeing Ana's expression that turns into a stoic look makes worry creep into his heart, he can see how calm Ana is for his sudden appearance inside her bed-chamber. It's almost as if she knows that he will be here.

'Something is wrong... How are you guys there?', Rex thought.

With the addition of the Pack Hierarchy System, Rex can now use telepathy on Gistella, Adhara, and also Kyran who occupies the first to third rank of the Battle Prowess Hierarchy.

Through telepathy, Adhara then replied, 'Most of them are only early and mid-sixth rank'

'I'm fighting one right now. It's easy dealing with them, we'll probably get to your floor in a minute or so. Just wait for us', Kyran's voice rings in Rex's head before he nodded his head.

<Sovereign of the Night Passive Skill has been Activated!>

<Increase all stats by 200%>

Ana widen her eyes when she suddenly feels a spike of Rex's aura that amplify his already terrifying aura twofold, it shook her but she realized that it was already night and Rex has just received the blessing of the moon.

She quickly collected herself before she said, "Follow me..."

Hearing this, Rex frowned seeing the nonchalant behavior. Ana even dares to turn her back on him which is a power move on its own, and this further develops Rex's weird feeling about the situation he's in.

'Let's see what this is all about, I doubt she will really lead me to Rosie', Rex thought.

Exiting Ana's bed-chamber, Rex follows her on the back while still keeping his alertness at its max. She leads Rex through the empty hallway heading to the stairs leading down.

While walking on her back, Rex finds that Ana is stronger than she was before.

<Ana Delarosa - Enhanced>

Race: Ancient Vampire - Queen

Power: Seventh Rank (Early) - Blood Fighter

Mental: 511

Strength: 1737

Agility: 2739

Endurance: 1611

Intelligence: 966

'Vampires here are enhanced because of that tree, she almost double in power', Rex thought with a frown, he's not worried about himself but about the others instead that are fighting below and taking care of the other Vampires.

But with Gistella there, they should be okay fighting these enhanced Vampires.

After thinking briefly, Rex refocuses on his situation before he turns the ground in the surrounding black. There are many doors here in the hallway.

He activates his Black Field Orko spell just to check if there's anyone behind these doors they are passing that is waiting to ambush him, but it seems there is not. Rex finds no one inside these doors even with the use of the spell, it's completely empty here.

Not long after, the both of them arrived in front of a big entrance.

Rex already senses two powerful auras standing beside the big entrance, taking a turn her then saw two Royal Vampire Guards that have an early seventh rank power. This makes him frown but in the next second,

BLITZ!

Brak!!

The ground trembles as Rex use his flash step and stab both Royal Vampire Guards right on their chest using the Amuerus Katana on the left hand and the Silver Eye on the right hand.

But unexpectedly, both Royal Vampire Guards turn into blood energy and dissipated.

Rex looks at this with a frown finding that they're nothing but an illusion, a blood illusion to be exact and it feels familiar. Even the notification from the system doesn't appear meaning that they're indeed an illusion. He straightens his back slowly before glancing at Ana on the back.

"You're being paranoid, they're only blood clones. I'm leading you to Rosie, there's no need to be alert", Ana said before walking past Rex and heading to the big entrance.

Hearing this, Rex scoffed, "What games are you playing?"

Just after he said that Rex suddenly feels something flowing down his nose, this made him touch his nose in reflex before he feel the tip of his finger in contact with a liquid.

With a frown, Rex looks at his fingertips and finds blood there.

The blood makes him grit his teeth realizing immediately what this means, 'She's near... I need to wrap this up before she came here with her Royal Vampire Guards', Rex thought before looking back at Ana that is already in front of the big entrance.

It's not that Rex is afraid of her, but she can't be killed right now.

As long as the curse still attached them together he won't be able to kill her even if he tries anything, even back then during their conversation through the blood mirror. Rex remembers that she initiate a quest from the system.

Super Berserk Quest to be exact, but it got immediately denied.

From this alone, Rex knows that whatever he does to her she won't die at his hands. Every time the system gave a quest, it identifies the possible solution Rex can do to complete the quest. It doesn't matter how hard to finish the quest, as long as there's a way then the quest is valid.

For the system to retract back the quest means that there's no way of completing the quest that the system was about to issue, and Rex knows that the quest is to kill her.

"Games? Then see for yourself...", Ana replied before she push the door open revealing its inside. The room turns out to be a throne room where a powerful Vampire is sitting on the throne, this Vampire had a peak seventh rank power.

<Delarosa Garth - Enhanced>

Race: Ancient Vampire - King

Power: Seventh Rank (Mid) - Blood Fighter

Mental: 1112

Strength: 10911

Agility: 8266

Endurance: 9933

Intelligence: 3288

Upon seeing this Vampire that seems to be Ana's husband, Rex frown as he realized that this Vampire has upper echelon mid-seventh rank power. He immediately steadies his breathing and activates the Vampire Bane Breathing Technique.

Instantly after that, his body got covered with Kinzite in case Delarosa attacked him.

But looking at Delarosa doesn't last long as Rex's eyes was attracted to a chained person below his throne, this woman is chained on all of her limbs while looking down weakly.

Just from the curly brown hair, Rex widens his eyes, "ROSIE!"

BOOM!!

Rex's aura blasted the surroundings cracking the ground beneath him and even making the entire castle tremble but from the outside, the castle doesn't look like anything happened at all. That is because there are a couple of runes that Rex bought from the shop just to make the illusion of the castle.

So no matter what happened inside as long as they don't leave the castle's territory, the castle will keep on looking normal from the outside.

Feeling the shattering and destructive energy that is coming from Rex's body makes Delarosa laughs excitedly, he can feel even his bloodline tremble in front of Rex's aura that contains mythical energy as a prince.

Not only that, his aura starts to get stronger by the second as Rex activates his Pure Brace of Moonlight skill, and red force while glaring at Delarosa.

Ana who feel the boiling anger and power coming from Rex sneakily went to Delarosa's side.

"Let her go, and I'll give you a swift death!", Rex mutters threateningly.

Hearing this, Delarosa snickers while looking at Rex in amusement, "I wonder what kind of Prince that appears inside the humans' territory will be like, but you're more Werewolf than many others. I'm impressed...", he praised.

Rosie who has her body very thin and frail moved after hearing Rex's voice.

She slowly raises her gaze, the power inside of her now is weaker compared to even a normal human. Rosie needs every inch of strength that she had just to raise her gaze. And after she manages to see Rex albeit blurry, her eyes start to get rejuvenated with life.

A crooked smile appears on Rosie's face, "Rex...", she mutters softly.

The soft voice that escaped Rosie's mouth seeped into Rex's ears making his body boil more in anger, his wrathful eyes look at Rosie who has bite marks on her neck. Even her body is not the same way that he remembered.

Even though Rosie is already a thing of the past, Rex can't deny that she's the first one to know about him being a Werewolf and even accepted him.

If he wanted to be honest with himself, the moment he saw Rosie that day in the Nokas Mall he falls for her beauty almost instantly. Her beautiful face, her hazel eyes coupled with her curly brown hair, and the tempting figure makes everything about her gorgeous.

But that woman that he saw in the Nokas Mall is nowhere to be seen, her hair is messy and shriveled, her hazel eyes are not bright anymore, and her body is thin almost like a corpse.

Rex grinds his teeth in anger before his body slowly makes cracking sounds.

Under Delarosa and Rosie's gazes, Rex slowly turns into his Werewolf form amplifying his mythical presence by a notch and also his suppressing power. The thirst for blood he's currently feeling right now is the most he has ever felt in a long time.

It's a miracle for him to maintain his absolute consciousness despite the feeling inside of him. The feeling of wanting to tear Delarosa and Ana right now is at its peak.

If not for the Berserk Quest having already been initiated to kill all members of the Delarosa Family during the day Rosie got kidnapped, the Berserk Quest might even turn into a Super Berserk Quest instantaneously.

"Wonderful... Such a marvelous sight", Delarosa commented.

Seeing a human turning into a Werewolf for the first time greatly pleases his curiosity, but Ana who is just beside Delarosa then approaches Rosie before she grabs Rosie's face and points it at Rex, "Look! Your lover is here to rescue you"

"GET YOUR HANDS OFF OF HER!"

BLITZ!!

<Blood Moon Blessing!>

<Bestowed Blood Abrigate Thirst Skill!>

Just like before, the Blood Moon gave Rex its blessing in accordance with his anger.

Devo appears after a spark of sky black lightning blasted beside Rex, his power raises according to Rex's power which puts him also in the mid-seventh rank realm.

While this is all happening,

The others arrived on the floor after clearing the Vampires below, all of them including Delta saw Rex riling his entire aura in front of two Vampires with one woman chained below the throne.

"Is that Rosie?"

"It must be, she's alive!!"

"Master..."

"We need to help Rex!"

Each one of the voiced out their thoughts while looking at this scene. The sight of Rex being very angry instills anger into their own body too, it's like Rex's emotion is resonating through them.

But when Rex's eyes glisten, his trembling body suddenly stopped.

The anger he felt instantly stopped as his wrathful eyes turn into a shock instead, he looks at Rosie in disbelief before out of nowhere the Silver Eye appears in his hand again. His eyes flash fiercely before he arrives in front of Rosie in a blink of an eye.

Ana widens her eyes upon seeing Rex suddenly dash toward her.

Delarosa who is on the back didn't sit still and activate his blood aura, but he was surprised to find that he was unable to use his blood aura. It's like the friction of energy that suppressed his blood energy inhibiting him to communicate with it.

But he still dashes to save Ana despite his movement being sloppy thanks to being unable to use his blood aura. Delarosa got blocked by Devo who slammed his body filled with lightning to him just enough to give time for Rex to thrust his Silver Eye.

Stab!!

"Haarghh!"

Under the others' surprised gaze, the Silver Eye stabs into Ana's heart.

The shocking part for the others is not the fact that Rex attacked Ana, but Rex thrust the Silver Eye through Rosie's chest first just to reach Ana on her back. It was done swiftly and this catches all of them off guard.

With how weak Rosie's body is currently, that stab surely killed her instantly.

Rex ignores Ana who is stunned in her place looking at the Silver Eye stabbing her, he looks at Rosie instead with a vicious expression, "I can see through your deceit"

"Calidora..."
