The Invincible Full-Moon System

"Your nose, it's bleeding", Liliya said while pointing at Rex.

Hearing this, Rex's body froze before he touch his nose to only find that his nose is bleeding.

Rex looks at his hand that has his blood on it before his eyes widen in surprise,

In a blink of an eye, Rex's body becomes tense and his expression turns dead serious catching Liliya and Adhara off guard since his whole vibe turns from relaxed to alert instantly.

BOOM!

Without thinking much, Rex activates his black lightning, spirit, and red force.

The powerful shockwave blasted from Rex's body pushing Liliya and Adhara back, even Delta who is right beside Rex got thrown away because of how powerful the shockwave was.

Rex instantly uses his full power as he glances at the surroundings warily,

Black lightning started blitzing around his body chaotically as his spirit energy amplified the black lightning making the people in his surroundings feel their element suppressed, red steaming energy also envelopes his entire body just above the skin.

Adhara and Liliya can feel a stabbing feeling on their bodies because of Rex's red force.

It was akin to getting their insides stabbed by somekind of a needle, the feeling is suffocating and prickly as the both of them stopped their body from being pushed back by the shockwave.

"Rex?!", Adhara shouted as she covers her face with her arms to protect from Rex's energy.

Liliya on the side also decisively creates a red barrier around her, Delta, and Adhara, she was also confused as to why Rex suddenly becomes alert.

They even saw Rex is gripping the Ameurus Katana tightly as if he was about to fight.

'Is she here?!', Rex thought while eyeing the surrounding.

The last time when his nose bleed is back when he becomes a Scavenger in the Supernatural Territory with Liliya, His nose bleed is because of his Eternal Curse the Female Vampire is near, Calidora.

She was accompanied by two Royal Guards, and her strength is not to be underestimated.

Although Rex has only met with Calidora two times, the increase in strength of Calidora almost matches Rex's speed and her eyes are the most troublesome out of all of her abilities.

So this makes Rex very alert since this is exactly like last time,

'This is the human territory, how did she get here? There's no way she will dare step this deep inside the human territory expecting to survive', Rex thought still ready with his katana.

But even after putting his sense to the max, Rex doesn't sense any Supernatural around.

Rex only saw the surprised look of the people around him upon seeing him become like this, he was already in his full power ready to fight at any moment.

He even unconsciously activates his Alpha Bearing suppressing the people around him.

"Rex stop!", Liliya shouted feeling her strength got zapped by something, she remembers Rex using this skill to the group of dark monkeys during their time as a Scavenger.

Hearing this, Rex snapped out of his caution before he retracts back his aura.

Some of the students around him fall to their knees after getting affected by Rex's Alpha Bearing skill, their chests are heaving up and down because of the suppression.

Rex straighten his back after realizing what he's done,

After he retracts back his aura, the others finally can breathe normally as Adhara approached him, "What is wrong with you? Why did you suddenly do that?", she asks feeling a bit angry and confused.

It happened suddenly, Rex went into his battle mode surprising the others.

This is the first time she ever felt being under Rex's Alpha Bearing skill,

Because Rex turns alert after thinking that Calidora might've been near, he even unconsciously uses the Alpha Bearing skill to everyone around him. He forgets to exclude Adhara from the skill or even anyone to be exact.

'Yeah, there's just no chance Calidora to be here', Rex thought as he lowers his guard.

The nose bleeds just caught him off guard, that's all.

This might've happened because of Sebrof Energy just like vomiting blood before, it can't be because of Calidora since they're in the heart of Ratmawati City.

But it still makes Rex cautious since Calidora told him that they will meet soon.

With a frown, Rex looks around one last time before he said, "I'm sorry"

"Did you feel someone will attack you or something?", Liliya said as she also approach Rex.

There is a disbelief look on her face after feeling Rex's power, it certainly increases since his force even raised to red color from the yellow color.

Deep down she was quite surprised by Rex's progression,

Hearing this, Rex glanced at Liliya as he thought, 'The last time, she's unconscious. So she doesn't know why I become alert like that'

It was Vanessa that told him that his nose is bleeding last time,

Liliya is unconscious because Rex knocked her out to avoid her from seeing his Supernatural aura, she's still knocked out even when Calidora met with Rex so she doesn't know.

With a guilty smile, Rex then shakes his head, "It's nothing, I don't know where that came from"

Both Liliya and Adhara look at Rex suspiciously, what Rex said is definitely an excuse but they finally let Rex go from the topic.

After suspiciously looking at Rex, Liliya finally bid her goodbye and left.

Rex was left with Adhara before his eyes landed on Delta who is not far from them, Rex looks to his back before he saw Ryze hiding behind a concrete park chair before he signals for Ryze to come here.

"So, What happened to Delta?", Adhara asks after noticing Rex is looking at Delta.

Delta is lying on the ground submissively, especially after getting knocked by Rex's energy shockwave, she's eyeing them from the side but averted her gaze when Rex looks at her.

Rex then explains everything to Adhara about Delta acting weirdly,

Hearing this, Adhara also frowns since Delta is very docile to them and very obedient to Rex so this kind of incident happening is surely weird.

She then glances at Ryze and asks, "When did she start being like this?"

"It started a while back a day before the four of you came back, Delta suddenly becomes excited in the middle of the night so the security asks me to check on her. T-Then, her excitement started to become too much before she finally snap", Ryze explain with his innocent look.

Rex and Adhara listened to this attentively with a frown,

'A day after we came back? Does he mean after we met with Ana Delarosa?', Rex thought.

But even after thinking for a moment, Rex still doesn't get why Delta suddenly becomes like this, "Did you notice anything else? Maybe someone angers her"

"I-I don't know...", Ryze replied meekly after recalling the last couple of days.

With a sigh, Rex decided to approach Delta followed by Adhara and Ryze although hesitantly on the back since Delta just snap a moment ago.

Rex squat in front of Delta before he rubs her head gently,

Delta growls lightly feeling Rex is rubbing her head, she looks to be enjoying it before suddenly her eyes lit up when she saw Adhara.

"Waahh!"

Adhara exclaimed when Delta suddenly jumped at her and push her to the ground.

Rex and Ryze panic for a moment before they sigh when they saw Delta is licking Adhara repeatedly, this caught Adhara off guard since this never happened before.

She never even have this kind of close relationship with Delta,

"Rex-- Help!-- Get her off of me!", Adhara pleaded while being licked by Delta.

Seeing this, Ryze chuckles for a bit seeing Adhara's helpless expression under Delta who kept licking and only leaving sticky saliva on her face.

Rex shakes his head and pulls Delta's head,

But Rex looks back at Delta when Delta freed herself, she's growling lightly towards Rex.

Looking at this, Rex frown since he can feel that Delta is trying to tell him something as her muzzle repeatedly went back from him to Adhara a couple of times.

Even so, Rex still doesn't get it, "What are you trying to say?"

"Do you want me to get rid of Adhara?", Rex added before getting slapped on the head by Adhara.

Rex rubs his head that got slapped as Adhara looks at him in disbelief, he then said, "Delta is pointing at your neck, What else should I think?"

"I think she's pointing at my rune", Adhara mumbles while looking at Delta.

Hearing this, Rex rubs his chin for a moment before he shakes his head, "I don't think so, Why would she point at your rune", Rex said before he finally puts Delta back in the mutated animals' place.

Delta is growling a couple of times to Rex but Rex ignored her,

She even tries to go back to Adhara but Rex stopped her and command her to get inside the place, he needs to do something and he didn't have the time to deal with Delta for now.

"Let's go back, you come back too Ryze", Rex instructed.

Ryze was looking at the mutated animals' place before suddenly Delta howls, but the howls have a hint of desperation in them and Ryze can hear this clearly.

It's rare to find Delta howling but Ryze saw it a couple of times, and it's definitely when she's sad.

Later, that same day,

During the afternoon and even until the day turns dark, Rex is reading the information he bought from the Undead and their Death Energy.

He needs to prepare a couple of things for the mission,

The situation is not clear whether the mission will start tomorrow or the day after tomorrow, but in case the mission will start tomorrow, Rex will need to finish his preparation today.

Adhara got inside the room and saw a couple of items on the ground,

Rex is tidying the items on the ground while thinking before he noticed Adhara enters the room, there are many kinds of things in front of Rex but many of them are vials.

Looking at this, Adhara asks curiously, "What is this?"

"I'm preparing for the mission, I really don't want to be a slave of the UWO for years if one of the descendants under me dies", Rex replied before focusing back on the items in front of him.

He then takes out a brown skull before he puts it upside down in front of him,

Adhara sits on the edge of the bed feeling curious about what Rex is doing, he even takes many items out of thin air as if he has an invisible pocket.

<Purchased Purifying Field Bomb creation guide for 10,000 Gold>

After preparing a couple of items, Rex crack his knuckle and started to work,

Rex started the process by putting a clear white flower that has a contrasting dark aura surrounding the petals inside the brown skull, he then proceeds to pour three vials that contain the brown liquid in them before he started to crush the white flower with a spoon that he got from the butler.

He mixed the ingredients and follows the instruction from the system exactly,

It takes about fifteen minutes before suddenly the mixed liquid inside the brown bowl started to glow with a darkish grey color, Adhara can feel an even stronger death property from the liquid.

But Rex didn't stop there,

Rex also buy a rune from the system's shop before the rune appeared on his palm,

After putting the darkish grey color liquid into an empty vial, he then engraved the rune on the vial before he raised the vial in front of his eyes,

Flick!

With a flick from Rex's finger, the rune glow before the liquid turns colorless.

This caught Adhara in surprise since the liquid should be darkish grey, but after Rex flicked it the rune glowed as the liquid instantly turns colorless.

Rex did this process a couple of times before three colorless vial lines neatly beside him.

"What are you making?", Adhara asks from the side.

Hearing this, Rex glanced to Adhara before he tidied the mess he made and explains, "I'm making a counter to the death energy embedded on the ground near Eqosa City, it should nullify the death energy so the Undead will not be at an advantage"

"Isn't the UWO have that kind of vial? I forgot what it's called", Adhara replied.

Rex shrugs his shoulders as he said, "I don't know what the UWO have, but this one is called Purifying Field Bomb. The items needed to make this is very rare, so I can't make much"

Adhara nodded her head before her eyes landed on a sword,

"Is that a Silver Sword?", she asks while pointing at the whitish sword in front of Rex.

Rex nodded his head as he picks up the sword, "I cover the handle so the Silver doesn't directly touch my skin, this will make it easier to fight the Undead", he said.

After saying that, Rex started to clean his mess,

But seeing Rex's sloppy cleaning Adhara becomes annoyed since he didn't clean it properly, after having enough of it she finally said, "You do remember that there are maids right?"

"It's not much, I can clean it", Rex replied nonchalantly.

Adhara looks at Rex with annoyance until finally, "Just let me clean it, step aside!"

"Okay?", Rex mumbles in confusion, he doesn't know why Adhara has an annoyed expression.

While Adhara is cleaning the leftover from before, she suddenly remembered and asks, "Have you visited Kyran? Where is he right now?"

"Kyran is in a hospital, I haven't visited him so can you go tomorrow?", Rex said.

Edward told Rex before that he was forced to bring Kyran to the hospital,

At first, Rex was confused since Kyran doesn't need to be brought to a hospital since he's a Werewolf. All he needs is the moonlight and his wounds should've healed by themselves.

But Edward told Rex that he uses silver to beat Kyran to submission.

This explains how Edward was able to survive with just a few scratches, turns out he's using silver.

Hearing this, Adhara nodded her head.

After finishing her cleaning,

"I'm going to start making a batch for Daniel", Adhara said but she suddenly saw Rex is changing his clothes, she was confused at first but then she realized why.

Rex put on a black T-shirt and black pants coupled with black shoes.

It should be weird for someone to wear all black at the night but knowing where he's about to go, Adhara finds it normal to wear these kinds of clothes.

"Alright I'm going to leave for a bit", Rex said.

Adhara looks at Rex's huge frame from the back, he even straps his Amuerus Katana on his back.

This is a new look for Rex as Adhara replied, "Do you really have to do this? You might get caught if you're careless with this, especially this will be used by the Atkins if you're caught"

"Don't worry, I'm just going to visit the Platchi", Rex said lightly.

But from the evil expression on Rex's face, Adhara is sure that he's not just going to visit.

With a sigh, Adhara then finally said helplessly, "I pity them so can you please not do anything rash? At least don't just kill him and leave"

"We'll see about that"
