The Invincible Full-Moon System

The scream of terror reverberated in the entire mansion as Mrs. Greene screamed in utter horror, she just saw that Gistella that looks lovely and very polite suddenly has claws and piercing yellow eyes. Anyone in her position will also be scared.

Her body is shaking as she curled on the ground grabbing her head with both hands.

Although she has seen that Rex has an association with the Supernatural such as Ugrok whom she met before, a Werewolf is a different story for her. Nobody can refute if they know her past.

Not only Rex but Mrs. Greene is also traumatized from that same night.

It was the devious eyes that are looking at her as if she was nothing but food, the pair jewels straight from the darkness, something that she too can't forget despite it occurred years ago. Maybe because of that, she has the urge to take Rex under her wing.

Knowing that she even traumatized herself, the effect is definitely stronger on a kid like Rex.

"Ma'am, are you okay...?", the soothing yet familiar voice seeped into Mrs. Greene's ears, she pulls her up and saw that Gistella is looking at her from the back. Turns out her back hits Gistella's legs.

But this made Mrs. Greene confused, she looks at Gistella before looking back at the room.

"W-Wait... h-how can y-you be here, I- I saw you inside...", Mrs. Greene mutters but she got a confused look as a reply from Gistella, if she just was about to go inside her room them the one inside shouldn't be Gistella.

There's only one Gistella, so this confuses her to no end.

Mrs. Greene stands up with the help of Gistella before she went inside the room hesitantly, she looks around the room and finds that no one is inside. She held her head in utter confusion, it was late in the night and she was presented with this kind of situation.

Although she trusts what she saw, Gistella comes from outside not inside the room.

It couldn't be her that she saw inside the room, that wouldn't explain how Gistella come from outside if what she was seeing is true, "I might've gone crazy...", Mrs. Greene mutters shaking her head in disbelief.

"Do you want me to accompany you back to your room, ma'am?"

Gistella offers politely seeing that Mrs. Greene is sweating and seems to be dizzy, she fears that she might not be able to get back to her room safely. But Mrs. Greene politely refuses with a gentle smile.

"It's okay, there's no need. I'm just glad that my scream earlier didn't disturb the others..."

After saying that, Mrs. Greene bids Gistella goodnight before she went back upstairs heading into her room. Mrs. Greene's body can be evidently seen still trembling from what just happened, her  footsteps make a light thudding sound before she finally reaches for the door.

But as soon as she enters her room, Gistella falls onto her knees.

"I'm sorry, master..."

Without even needing to look back, she can already feel Rex's presence standing behind her. Even his shadow with the moonlight behind him already shrouded Gistella's entire body in darkness, and his cold eyes show clearly that he's displeased.

Fearing that Rex's anger will climb higher, Gistella immediately explained herself.

"I- I was focusing on getting u-used to transforming my body that I was caught off guard by her appearance, s-she has never gone inside my room... I d-didn't expect that she would- I'm sorry..."

Albeit scrambling with her words, Gistella tries to explain herself.

What Mrs. Greene saw earlier is certainly Gistella, she was also surprised to see Mrs. Greene peeking into the room and just as Mrs. Greene stumbles back she has quickly gone outside the window of her room and came from the backyard.

Gistella move so quickly that Mrs. Greene didn't even notice she came from the backyard.

It was her quick thinking realizing that Mrs. Greene saw her hands are claws and she need to do something to convince Mrs. Greene that she saw it wrong and seems like it works judging from Mrs. Greene's reaction to seeing her.

But then again, this shouldn't happen in the first place with how powerful a Werewolf's senses are.

The senses of a Werewolf can be said to be the most sensitive out of the Supernatural race, especially their smelling sense which is certainly the strongest. For her to do such a blunder makes Rex fuming in anger.

His face is burning in anger, Gistella should've been able to sense Mrs. Greene before she even gets near her room let alone peek inside the room.

Rex was meditating in the throne room when he heard his mother scream at the top of her lungs, he thought that someone is attacking the mansion but it turns out it was Gistella's doing instead. He already watches them from the second floor unknowingly by Mrs. Greene.

Of course, Gistella already knows he's watching from the second floor.

In fact, even Edward, Kyran, and Adhara also already noticed their exchange but kept in hiding so that Gistella can convince Mrs. Greene otherwise. It's going to be harder if they intervene.

With slow but deadly steps, Rex walks around Gistella before stopping right in front of her.

Grabbing Gistella's face with clear anger on his grim face, Rex forces her to look at him which has his fangs protruding out of his mouth sharply. Dark energy already starts to cloak his four sharp fangs while he glares at Gistella, "My mother has a trauma of Werewolves..."

"And your carelessness makes her remember that night again", Rex mutters grimly.

Although he has already opened up to Adhara about his past when his parents are killed, Gistella doesn't know about his past and also the fact that Mrs. Greene is present that night and witnessed everything that happened.

Despite her trying to cover it up, there are some days that Rex noticed her weird behavior.

Being scared when she's alone in the darkness, sweating when she saw the news about Werewolves, and many other instances throughout his life lead to him knowing that she's also traumatized.

In fact, that trauma is why Mrs. Greene really likes shopping and being in a crowded place.

Mrs. Greene is also the one that consoled him during visiting time when he was still in the Noob Box, she knows exactly what Rex has always dreamt about that night, and experiencing it herself makes her know the pain he felt every day.

Saying that she was the most precious person in the world for Rex is an understatement.

Tears started to well up in Gistella's beautiful blue eyes and it didn't take long for her eyes unable to contain the tears and let them fall down her cheek, but despite her pitiful look, there was not a hint of mercy in Rex's eyes.

Rex activates his newly gained skill amplified by the Countess,

Back during snapping out of his rampage in the Vampire territory, he finished an achievement and gained the Royal Bite skill that got turned into the ultimate form by the Countess into Absolute Predominance Fangs skill.

This is the first time using the skill, Rex's fangs got cloaked with the dark moonlight energy.

It's a skill that is similar to his Berserker's Curse skill that can turn moonlight energy into the blood moonlight energy, but this Absolute Predominance Fangs skill converts moonlight into dark moonlight energy.

Although Rex has never used it, he has read the description of the skill.

Basically, this skill is like the ultimate form of a wolf bite that can instill dominance, induce pain, and weaken the target that he bites and it's an absolute skill that means unable to be resisted if the target doesn't have any skill similar in terms of power.

Werewolves in the legend are known to have a very deadly bite, this is the ultimate form of that.

Rex grabs Gistella's head by the hair before he tilts her head to the side, he then leans his face closer to her exposed neck intending to bite her. The pain and agony that she will feel after the bite will be her punishment for her hurtful blunder, she didn't resist and just let Rex do whatever he wants.

She didn't deny that it was her fault and that she deserved to be punished.

But just as Rex was about to bite her neck using the Absolute Predominance Fangs skill, Adhara who is watching from the side intervenes, "Stop!"

Growl!

With his eyes glowing red, Rex turns his neck at Adhara startling her.

"L-Let me be the one to punish her, I'll challenge her in a fight. Don't worry, I won't go easy on her", Adhara hesitated at first seeing the wrathful look on Rex's face but she decided to go on with her proposal.

But upon hearing this, Kyran glanced at her with a frown.

Although she said it so confidently, Kyran looks at her in doubt knowing their strength.

Despite not being talked about with the current circumstances they are in, everyone knows and acknowledges that Gistella is the strongest pack member just under the Alpha. She has seventh rank power and even her innate bloodline ability is basically broken.

It's clear that her bloodline, Werewolf Fiend is a bloodline innately for combat.

Not only does her bloodline has the highest potential for combat, but she is also adept in defense-skill that she already learned from the Undead making her devastating support to the pack.

Hearing Adhara openly said that she won't hold back makes Kyran sneer.

'What is she saying? How can she punish Gistella if the fact that she will prevail is still doubtful', Kyran thought shaking his head, he definitely trusts that Rex will not even consider her proposal as it was too ridiculous.

But contrary to his expectation, the words that came from Rex's mouth shocked him.

"Fine...", Rex said letting go of Gistella's hair roughly.

Kyran was utterly baffled hearing that Rex agreed to the proposal, he was not expecting Rex to accept Adhara's proposal at all. This prompted Kyran to gaze at Adhara in disbelief, 'I sensed that she's different and should be because her bloodline just evolved, but what on earth did she turn into?'

'Gistella is an absolute monster, how can her bloodline cover that huge gap...?'

It's still surreal for him to witness this, Rex agreeing basically means that he trusts that Adhara is able to beat Gistella in a fight. That alone shows that he recognized Adhara as that powerful.

<Does the user Adhara Alpenore challenge Gistella in a hierarchy fight?>

'Yes...'

Rex replied in his head before shifting his gaze back to Adhara, he walks closer to Adhara before he stops just in front of her with a cold look, "I'll let you be the one to punish Gistella for her blunder, but if I see you hesitate then I'm going to bite you instead and let Gistella of the hook. Is that okay with you?"

Hearing the grim cold tone Rex is using, Adhara felt her throat dry.

Although she has seen Rex angry numerous times and even went berserk, the anger he's feeling right now is completely sane without any influence of his Werewolf side. It's outright terrifying.

But Adhara knows that she did the right thing,

From the past he told, she knows that Rex will not hold back on Gistella.

One might think that it's not something heavy if Mrs. Greene knows that Gistella is a Werewolf, she knows that Rex has some Supernatural pet and Rex can just bluff and say that Gistella is also another one of his Supernatural pets.

It seems easy, but that is not the point.

Rex is angry because Mrs. Greene is there that night, and Gistella just awoke her nightmare again.

That alone makes the anger bubbling inside him reach an insurmountable height of his calmness, it's not a surprise if he will beat Gistella half death if Adhara didn't intervene.

"Okay... I have no problem with that", Adhara finally replied.

With that out of the way, Rex gazes at Adhara's eyes for a couple of seconds longer before turning away. He heads to the second floor intending to check on Mrs. Greene, "The Challenge will be done two days from now at the same time as now", Rex said before ascending the stairs.

After he left, Gistella wiped her tears before she went back to her room hanging her head low.

Ever since she becomes a Werewolf the innate desire of pleasing Rex has been there all along, but now she just wrecked everything from that one blunder she did. She's cursing herself inside her head non-stop.

She didn't even say anything to Adhara and Kyran and just went back to her room and close the door.

Adhara can only sigh as this shouldn't be happening as there are more things to prepare for, but just as she was about to head back she saw Kyran looking at her curiously, "Since when did you get the confidence in beating Gistella?"

"Just about a couple of days"

"It's your bloodline huh... I can sense your change but what did you turn into?"

Narrowing his eyes peeringly, Kyran is definitely curious as to what kind of Werewolf she turns into. He also feels that he was nearing his evolution, and this makes him anticipate his evolution more.

Giving Kyran a smirk, Adhara then replied, "You'll see..."

"Do you reckon that you can also beat me then?", Kyran asks as his dark element starts to rile.

This makes Adhara's fangs sharpen as she gives him a condescending smile, "I'm the Female Alpha, before my bloodline evolution I'm still stronger than you. Or do you have other thoughts, Kyran...?"

"Stronger than me huh...", Kyran mutters softly with a hint of disapproval.

But before he can say more, Adhara continues, "Sadly, we can't undo the time and duke it out. I already evolved into a higher being. As for our future fight, in two days' time, you're going to see my power"

"And when you do, you're going to realize that even if you evolve you will still unable to beat me"
