The Invincible Full-Moon System

Rex looks up to the sky with the feeling of immense pain still lingering on his pierced chest, he was still breathing heavily as the demonic energy leftover that is still present inside his body runs rampant. It makes his entire body numb.

With everything he got except for turning into his Werewolf form, he still got overpowered easily.

The help from Adhara, Evelyn, and even Gistella should be more than enough but the disparity in strength is just way too much. It needs to bare in mind that most of the spear power already got blocked by Denzel before.

Most of the original strength behind that spear is gone, and its momentum is weakened heavily.

And despite all of that and also the spells that Rex used to keep reducing the spear's momentum, it takes literally every strength in his and the others' bodies to just change the spear's direction.

If Rex doesn't remember that he can actually call for Gistella through the Crying Howl that she gets from the Battle Prowess Hierarchy feature and also bestow her the Berserker's Skill through the Alpha's Wisdom which is also thanks to the Battle Prowess Hierarchy feature, he might just force to use the Invincible Item.

​ Rex still got two of the items but it's very hard to find a moment to use them.

One such moment just presents itself just now but with Denzel looking in his direction the Werewolf Aura that comes from the King Mark after activating the Invincible Item will be a very big problem.

Without a doubt, Denzel will know that Rex is a Supernatural in disguise.

No matter how much contribution that he gives to humanity in order to fight the Supernatural, everything will go down the drain and he will instantly be labored as a Supernatural.

Just like the saying goes, a thousand good things are forgotten because of one evil.

Rex remembered that saying clearly since it was his birth father that told him that exact sentence after he just lost his job, and although it was way before the night that they died. He somehow remembered it clearly.

Maybe because of that he's really cautious of being exposed as a Werewolf.

But thankfully, the spear finally got parried and flung away after a gruesome struggle against its energy and piercing momentum. The result of that collision is bloody, Rex's hands are in a mess.

Some of his fingers are non-existent while the rest of his hands are left with exposed bones.

Although his hands will definitely regenerate after deactivating his Berserker's Curse skill, it's been so long since he has received such a gruesome attack that has the potential to kill him. And looking at the others, they all experienced the same.

The worst ones are Evelyn and Adhara's hands, half of their hands are gone.

Both of them are the longest ones to hold the spear in order to help Rex, that was a reckless move but Rex didn't blame them as if he were in their shoes then he will do the same.

Adhara looks at her hands before she fell to the ground with wide eyes.

With the spear successfully parried by them, the adrenaline that rushes inside her blood slowly fade away as the pain from her hands started to become more evident. She can't help but hold her hands in front of her stomach in pain and bend down until her forehead touches the ground.

Just like Rex, the others have also experienced the feeling of turning into their Werewolf form.

Throughout the pain that he has experienced in his life, Rex will answer turning into his Werewolf form for the first time is one of the most painful experiences. It's simply gruesome and painful.

Adhara has felt that pain the most just below Rex, so getting her hands halved should be nothing.

At least that is what Rex thought, but seeing her condition right now he can tell that Adhara is in an enormous amount of pain as her eyes started to get teary. Evelyn also did the same.

Rex sits up upon looking at this before he glanced at their hands.

'It's the demonic energy... although I'm fine, they're clearly not', Rex thought with a frown.

Maybe it's because of his bloodline as a prince or even his element that reached the Ultimate Rank, his body can fend off the demonic energy but Evelyn and Adahara can't. They're in agony as they started to shriek being unable to endure the pain.

With a swift movement, Rex deactivate his Berserker's Curse skill and went to them.

Looking at the two that are on the ground trying to desperately endure the pain from their hands, Rex then touches both of them and asks the system, 'System, what should I do to help them?'

<Pure Vulzavith Demonic Energy is rampaging inside Adhara and Evelyn's bodies>

<The user can imbue as much mana into their bodies to repel the Pure Vulzavith Demonic Energy, with the effect from the Magedamia Mandarin still active this solution is the best course of action. Start from their heart media and push the demonic energy out>

<Upon reaching the heart media, Adhara and Evelyn will be crippled and suffer a slow death>

Rex reads the notifications from the system before he instantly went to work without a moment's hesitation, "I'm going to help you, don't fight the energy I'm putting inside of you", he said before glancing at Adhara and Evelyn.

Both of them who are still in pain forcefully nodded their heads in confirmation.

Seeing the both of them nod, he started to focus on imbuing his Sky Black True Lightning element mana into Evelyn and Adhara's heart media before slowly creating blockages in case the demonic energy got close.

With his high level of mana control, he's able to do that in just a minute.

But even though his level of mana control is high especially since he unblocks the mind impression back on Hans' son, the one that made it easy to create the blockages is Devo himself.

Devo is made and born from lightning, so he's exceptionally good.

It's just energy-consuming for Devo to help Rex directly in doing this, so that is why back then he didn't help at all but now it's different. After creating the blockages, Rex starts to shove his mana into all of the entrances to the heart media.

Every last bit of the demonic energy is slowly being pushed back, but it's very slow.

During Sebrof's suspicion of him being a member of the SCO, he infiltrated Rex's body using his Arcane Mana and the system told Rex that he needs months to repel the Arcane mana. This demonic energy should be at that level.

Now Rex is way stronger than before, and also has help from the Magedamia Mandarin effect.

While he's focusing his mind on repelling the demonic energy, Gistella who is not in a state as bad as Evelyn and Adhara glances to the side when she hears something. Rex also did the same as her.

Both of them saw the spear that stabbed on the ground move.

Since this spear is thrown by a ninth-rank demon that is powerful enough to even went past Denzel's defense, it's certainly not a normal spear. The entirety of the spear is made of black materials that make it glisten under the sunlight.

Dark blue demonic energy still burns the tip of the spear that is shaped like a wavy triangle.

On the base of the head of the spear, there is a two-curving back extension of the blade towards the spear's socket that gives the resemblance of two acute wings of black metal. And just below the head of the spear lies an eye that is moving left and right disturbingly.

The spear slowly got pulled out of the ground before it stands straight.

Rex becomes alert but he kept repelling the demonic energy inside Evelyn and Adhara while Gistella already forced herself to create a bluish barrier in case of the spear attacks again.

Out of their expectation, the eye suddenly glows blue before a fiery figure appeared.

Just from the shape of the fiery blue figure alone Rex already know that this is the black charcoal demon that threw the spear earlier, it's the ninth-rank Archdemon...

"I've expected no less from the Royal Black Prince of the Werewolf"

"You are born in less than a year and yet you reach such terrifying strength, I'm impressed... the whole of Demon Kingdom is impressed. Truly an anomaly of the Origin", the fiery figure said while rubbing its chin with its index finger.

Hearing this, Rex's expression turns grim, "Who are you and what do you want from me?"

"Berserker's Curse... Red Force... Black Lightning Spells... Aren't you the perfect warrior capable of literally anything? That doesn't sound fair, don't you think so?", the fiery figure said.

Although the fiery figure doesn't have a mouth, Rex can see its smirk through its squinting eyes.

'He's testing my power... but the ones that knew about me being the Royal Black Prince are only the Vampires, Calidora must've gone ahead and told it to her parents. What a headache...', he thought before slowly standing up and facing the fiery figure after repelling enough demonic energy from Adhara and Evelyn's bodies.

Rex's human fang turns into animal fangs as he glares at the fiery figure, "You're going to pay..."

"I'm going to make the Demons pay the overdue debt they owed Humanity, I did it to the Delarosa Family and surely I can do the same to your kingdom", he added threateningly.

But instead of fear, the fiery figure doesn't seem to be disturbed.

The fiery figure then said nonchalantly, "I know you can, I never doubted you but..."

"You won't be able to hide behind Humanity for long... living amongst the humans, that is such a dream come true right? But what if it's really just a dream and the demons wake you up?", he added with a fierce look that makes his body explode with a demonic aura.

Although what the fiery figure said is vague, Rex grasps the hidden meaning behind it.

Upon realizing what the fiery figure is trying to say, Rex's expression darkens.

This dark expression makes the fiery figure smirk while crossing its arms in front, "King Saruth is all-knowing. In his eyes, you're just an opened tome, desperately trying to hide your Werewolf side"

"Nobody can hide from what they truly are, you don't belong here... it's about time you wake up"

"Let's see what will happen when you get kicked out from the human territory"

While saying the last sentence, the fiery figure's body slowly dissipated back into the eye before the entirety of the spear itself dissipated into blue sparkles of demonic energy. Gistella who heard about this from the side looks at Rex in concern, "Master..."

Rex clenched his fists that are almost completely healed powerfully.

He clenched his fists so hard that blood started to flow down from both fists, what the black charcoal demon said greatly angers him and it hits right on his weakest spot.

It's bad enough that Prof. K almost finished the Supernatural Radar, but this is just way worse.

Although the Supernatural Radar will work with any Supernaturals that try to infiltrate humanity, Rex has the system and surely will be able to bypass the Supernatural Radar. Rex has faith in the system, but what that black charcoal demon said is way worst than this.

Based on what the black charcoal demon is saying, the demons will try and expose Rex.

Rex doesn't know what kind of tactic they will use to try and expose him, but if they succeed then even the system will not be able to help him. If humanity knows what he really is, it's game over.

The hope of still living amongst humans is going to be nothing but a pipe dream.

Everything that he has built in humanity's ranks will be gone just like that, and just thinking about it makes his blood boil. Demons in the legends are despicable creatures that are made with fire and also a creature the opposite of angels.

They crawled out of hell just to manipulate humans into doing bad things.

Many call them the Bringer of Doom, the Abandoned Ones, or even the Children of Hell. But they're certainly the dweller of hell, a place that is filled with agony and blood of those who sins.

With his contorted look fuming with anger, Rex looks back at the demon stronghold.

"Children of Hell? Bringer of Doom? You're going to be my next target after I finished dealing the Werewolves, and do pray that I die in the process because if not then I'll show you the true sight of hell"
