The Invincible Full-Moon System

Creak...

The door of the master bedroom opens as Calidora walks out,

Delarosa who is waiting for her in front of the door glance at Calidora who has a hint of excitement in her expression but then, Delarosa frown when he suddenly heard a subtle voice.

"ANA!", Delarosa rushed into the room hurriedly.

Upon entering the room, Delarosa's eyes widen as he saw Ana miraculously already sitting on the bed albeit still looking sickly but there are some changes that can be seen.

The blistering neck that she had is not as nasty as before, it's almost as if she got better.

Looking at Ana who is smiling weakly at him, Delarosa glance at Calidora in disbelief as she suddenly said, "I was also surprised when I saw her open her eyes, it's a miracle"

"Your presence is blessed by the Origin, please accept my humble gratitude", Delarosa said.

He bent his knees to the ground gratefully, he was very thankful from the deepest part of his heart since Ana's condition only get worsened by the day.

Even humans blood doesn't help Ana at all and he was desperate.

Delarosa is prostrating in front of Calidora, and this makes Calidora hurriedly help him up as she said softly, "You're one of the royals, there's no need for this"

"Nevertheless, I'm grateful for your visit princess", Delarosa replied stubbornly.

The sight of Ana getting better touch the deepest soul of Delarosa as he added, "If you need anything at all princess, my family swear to help you to the best of our abilities"

A nasty grin appeared on Calidora's face but she turns back to normal almost instantly.

"Anything?", Calidora mumbles softly.

Without any hesitation, Delarosa replied firmly, "Anything, just say the words princess"

"If that's the case, Can you help me with one small thing? I need you to link me to the owner of this blood and after that I want you to locate him", Calidora asks covering her mouth with her other hand to hide her excited smile from Delarosa.

A moment later,

Calidora is sitting in the guest room before she saw Delarosa come into the room.

There's a solid rock in his hand with a red glowing rune on it that seems to hold a magical spell, he then presents it to Calidora before he said, "Princess, this is the thing that you requested"

Hearing this, Calidora takes the rock gently with her slender fingers.

She was looking at the rock with an excited expression before Delarosa added, "The rock will slowly crumble as you're connected to the blood owner, I've put everything in my power into that rock"

"To locate the blood owner's location accurately, princess needs to stall time until the rock crumbles completely. Since I put everything I had into that, it won't take long", he added.

Calidora is smiling excitedly exposing her beautiful fangs hearing this.

She then glances at Delarosa with excited eyes, she then hugs the rock as if it's the most precious thing in the world, "I'm grateful, Delarosa..."

Back to Rex,

CRACK!

BOOM!

The female Undead that was about to enter a dark portal to flee from the place suddenly got blasted away after a lightning bolt strikes down from the sky and destroyed the dark portal.

She was thrown away just from the impact of the lightning strike hitting the ground,

After the lightning strike dissipated, Rex's body materializes from the lightning particle before his fierce eyes landed on the female Undead making her crawl back in fright.

Rex is looking at the female Undead as he approached her slowly,

"Please! I'm sorry, I'm sorry for trying to run away... I'm sorry!", the female Undead pleaded seeing Rex is getting closer to her step by step.

The sharp black-steel claws of Rex glisten under the moonlight,

His piercing eyes and monstrous form shaded by the moon on his back increase the terrifying air around him, the female Undead crawls back fearfully before her back hits a black spear with a human corpse on it.

Rex then stops in front of her before he slowly stretches his hand,

Grip!

The female Undead's body is trembling non-stop as Rex grips her neck and lifts her off the ground, his claws even stabbed the female Undead's neck.

"I-I'm sorry...", the female Undead pleaded meekly.

But Rex didn't mind her plead as he said with a cold tone, "You're asking forgiveness after what you did? Do you really think I'll let you slide?"

Hearing this, the female Undead is confused but she still replied, "I'm sorry"

"Not only did you massacre the humans, but you also impaled them and even disgrace them with your filthy symbol. After all of that, you still have the audacity to plead for mercy?", Rex said coldly, he's still burning with anger from before.

The female Undead then replied, "I'm sorry..."

"We don't-" *Gasp* "have any choice", she added meekly while getting choked by Rex.

Rex frowns upon hearing this, he puts more strength into clenching the female Undead's neck, he then brings the female Undead face closer to his.

The absolute terror is etched on the female Undead's face as Rex shouted, "Lies!"

BAM!

With a swing of his arm, Rex throws the female Undead roughly.

The female Undead hits the trees on the side before stopping, she stands up slowly with her trembling body as Rex approached her once again.

All the other Undead are rooted in their spots, and even some are starting to flee.

But Rex didn't care since they will just regroup with the other company, and he can kill them later after finishing the Undead here, especially this female Undead.

Rex walks slowly toward the female Undead but his eyes widen when he saw the female Undead.

'My throw shouldn't be that hard, why is she not running?', Rex thought.

Despite him giving the female Undead a chance to run intending to humiliate her by chasing her like a wolf hunting a sheep, the female Undead did something unexpected that even Rex finds surprising.

The female Undead is prostrating on the ground as Rex approached her slowly,

"Forgive this lowly and worthless self of mine, M-master...", the female Undead mutters submissively as she puts her head on the ground in front of Rex.

Hearing this, Rex frown as his eyes scans the female Undead once more.

<Gustava Xix Scteztic>

Race: High Undeadlord

Power: Sixth Rank(Peak)

Mental: 409 (-210)

Strength: 603

Agility: 917

Endurance: 676

Intelligence: 1144

Reading the female Undead's stats, Rex frown since her stats are as expected stronger than the two Undead fighting him before.

Her stats even triumph over Rex's default stats, she's very strong.

p But the frown on Rex's face didn't fade as he looks at the female Undead, Gustava prostrating on the ground submissively even after Rex throw her away.

She didn't even use any spells or even try to resist.

At first, Rex wanted to humiliate her by chasing after her when she intends to run away.

That is why Rex threw her away to give her an opportunity to run but instead of running, Gustava prostrates on the ground waiting for Rex to come to her and keep on apologizing.

With her stats especially her intelligence stats,

Rex knows that if Gustava wanted to, she can use her variety of spells to flee and are certainly stronger than his spells even if he also imbued spirit energy.

At the very least she can run away,

Looking at Gustava prostrating on the ground, Rex then thought, 'Why is she not struggling? and what's with her calling me master all of a sudden'

This situation is weird, even Rex feels weird.

'System, Is the Werewolf race superior to the Undead race?', Rex asks.

<No>

<Undead is an entity that can manipulate death and can even use its energy to conjure all kinds of spells, they're an immortal that is very adept in death magic. Werewolves, on the other hand, they're living cursed creatures of the night reliant on the full moon. In a way, Werewolf is inferior to Undead if not for the full-moon>

Reading this, Rex becomes even more confused about the situation he's in right now.

"I-If it will please you...", Gustava suddenly mutters attracting Rex's attention.

Under Rex's very eyes, Gustava started stripping her armor leaving only a black piece of black dress that covered her body under the armor.

This makes Rex even more surprised since she deliberately puts herself in a defenseless position.

She then ripped the chest area open as she added, "You can play with my heart"

The ripped part of the dress exposes Gustava glowing beating heart that can be seen through her pale skin, it's beating roughly almost as if she was not an Undead and a living being instead.

But Rex can feel and hear that the heart is not functioning like living creatures,

Although it's beating as if it's pumping blood through Gustava's body, it doesn't and it pumps death energy throughout her body instead.

'What is that?', Rex thought with a frown.

While showing her beating heart, Gustava turns her head away and closed her eyes exposing herself as she waited for Rex to make a move while biting her lips fearfully.

It's like she's trained to do this, but Rex stands rooted on the spot in disbelief.

He's too shocked about the situation,

"If torturing me doesn't please you then...", tears started to flow down from her eyes as she crawls to Rex's feet and holds it with her cold hands, "you can kill me however that pleases you", Gustava added making Rex snapped out of his daze.

Seeing this, Rex was about to leap away thinking that Gustava might do something.

But his body stopped when he saw Gustava's body is trembling, she didn't even try to attack Rex even though her hands are practically touching Rex's leg.

If the Undead before manages to do this, his skin will be sizzling with Death Energy right now.

Rex then squats down before he grabs Gustava's silvery long white hair and pulls it back, he pulls Gustava's hair to make her look at his eyes, "Krmmph!"

Upon feeling Rex grab her hair, Gustava's body jolted.

"I-I'm sorry...", Gustava mutters softly as she kept her eyes closed still filled with tears.

While holding Gustava's hair, Rex glances back at the staked humans before he looks at Gustava fiercely, "Who instructed you to do this? Who told you to impale the corpses?"

Gustava whimpers lightly as her lips started to quiver,

"ANSWER ME!", Rex shouted in his low-baritone voice with clear anger.

The shout makes Gustava's body jolt before she answers with a trembling voice, "I-It's the commander, h-he said that this will bring the humans' morale down"

"Where is he right now?", Rex asked again but then suddenly,

SWISHH!

A couple of ice daggers attacked Rex from the back, Rex didn't move from his spot even after sensing it as the ice daggers crumbles upon hitting Rex's body.

Not a scratch appears on Rex's body, the ice daggers are too weak.

Rex glances to the back and finds five liches that just used a spell to attack him, he glances at him fiercely before one of them then said, "Let go of her! Take your filthy hands off of-"

CRASH!

Without even waiting for the lich to finish talking,

Black lightning tentacles burst from the ground and impaled each one of them, they all died instantly without even knowing what happened to them.

<Killed an early fifth rank Supernatural, Obtained 500,000 Exp>

<Killed a peak fifth rank Supernatural, Obtained 1,300,000 Exp>

<Level up!>

<Obtained 3 Attributable Stats>

Killing the five liches raised his level to 42, but Rex didn't pay it any attention as he glance at Gustava again, "Let me ask you again, Where is the commander?"

Although Rex already anticipated a more powerful Undead,

The aura that he felt before is gone, he can't feel the death energy coming from that hiding Undead that Rex guessed should be the commander Gustava speaks of.

But when Gustava was about to answer again,

"I'm here..."

Hearing the soft whisper, Rex widened his eyes before he suddenly sense an attack coming from the side, he instantly raises his arms to block the attack.

BAM!

"Krrghk!!", Rex grunted feeling the power behind the attack.

CRASH!

Because of blocking the attack, Rex crashed into hundreds of black spears with corpses on them and destroyed all of them that gets hit by him.

He only stop after got blasted for about 200 feet,

Rex looks at his arms and finds sharp needle-like bones stabbing his arms, he can feel the death energy in them as he pulls them out before his injuries started healing.

After doing that, Rex looks at his front and finds the Undead that he's looking for.

There is a powerful Undead permeating death energy so thick that it looks like a waterfall, its body way bigger than Rex who is in his Werewolf form.

BANG!

From a step of this Undead, the ground cracked under its heavyweight.

Rex stands up while brushing the dust off of him before a nasty grin baring his fangs appeared on his face, but his grin disappears when suddenly,

Swoosh!

Death Energy around the place got sucked into the Undead's head,

Rex looks around the place as his eyes widened feeling that the scale of this Undead absorbing the death energy is no joke, his absorption scale encompasses the entire place.

It's a jaw-dropping scale that makes Rex's senses alert,

The death energy gathers on the Undead's forehead where somekind of black crystal is located, the crystal grows more violent by the second until suddenly,

ROAR!!

BOOM!

A shockwave of death energy exploded from the Undead's body burning Rex's skin.

'What the? It actually managed to push me back even though I'm in my Werewolf form?!', Rex exclaimed inside his head as he tries to resist the shockwave of death energy.

After the shockwave ended,

The Undead breathed a black aura as its eyes landed on Rex while emitting violent killing intent.

Rex's eyes glisten while looking at the Undead scanning using the system, but he sucked in a cold breath when he saw the Undead's stats, 'It's the seventh rank Undead...'
