The Invincible Full-Moon System

Rex stood there in his spot without moving an inch while Agatha kept pulling on him.

She was baffled that she can't even pull Rex off of his spot, it was like pulling on a wooden totem that is already engraved into the ground by the Enchanter. Completely unmovable no matter how much she tried.

"Please, it's been ten minutes and my Uncle would arrive any moment now", Agatha pleaded.

Upon hearing this Rex's expression turns from indifferent to troubled, he was looking straight at Agatha that is still trying so hard to help him leave the place For a second there he clenched his other fist.

It was nothing but a thought but the urge to kill Agatha right now is knocking on the door.

Even the fact that he didn't kill her right now is completely insane as his entire body is already trembling, and his fingernails slowly turn back and forth to claws from these conflicts of feeling.

Blood slowly seeped out of the fist from the claws stabbing his palm.

"Why would it matter to you whether I die or not here?"

"Eh...? What do you mean why? Isn't every life must be treasured?"

"We're at war, and you're treasuring my life...?"

"Okay I get it I'll talk to you but let's go somewhere first, you're going to die! Can you not understand?!", Agatha exclaimed emphasizing the last part to try and make Rex understand.

Even though she already try to make it clear, Rex still stubbornly hold his ground.

"Give me your reason or I won't move from my spot"

Agatha bit her lower lip finding the human in front of her right now is very weird, despite her warning that her uncle would be here any moment Rex didn't care even though he might die if that were to happen. On top of that, he even insisted on talking with her.

But even though she wanted to answer, she finds it difficult to let the words out.

'Why is she hesitating, I want to know. Is it fear...? No, that can't be right because there's no bleak aura coming out of her', Rex thought with a frown, he was trying to find a reason why she seems to be reluctant to answer his question.

Continuing the pull, Agatha then said, "Get out of here! I don't want to see you die!"

It went out for a couple of more minutes as Rex stood on his spot waiting for her to answer, and Agatha realizes that it was useless to tell him to go if she didn't answer. Without a doubt, this human is not a regular human.

Exhaling roughly with both of her hands on her waist, Agatha can't help but shakes her head.

Not only was this the first time she actually met a human, but he was different than the ones that she heard from the others. Based on her knowledge of humans, there are two types of humans and one of them is the scared type.

Since they were in the Werewolf territory, Agatha assumed that Rex would be scared.

But looking at Rex once again that is standing and waiting for her to answer, she was stupefied as this kind of human that likes to ask questions is not aligned with her knowledge, 'I don't want to answer him, I'm embarrassed...'

Looking at Agatha that finally stopped pulling, Rex studied her expression intently.

"Just answer the question, Agatha..."

Upon hearing this, Agatha widened her eyes in surprise, "You know my name?"

When Rex was about to nod his head intending to sway Agatha to answer his question, his eyes suddenly widened seeing notifications from the system appearing in front of him before suddenly, "Huaakhh!", he falls to the ground on one knee.

Rex covers his mouth and finds blood gushing out of his mouth, it was very sudden.

<5% of the user's soul has been extracted!>

<The user's soul has been reduced to 10%, finish the Super Berserk Quest to recover the lost soul>

"Are you okay?!", Agatha also knelt in worry when she saw Rex suddenly coughs a mouthful of blood, in a split second she thought her uncle launch an attack but thankfully it didn't come to that.

Still coughing more blood out, Rex raised his free arm to signal something.

It didn't take long before a small pool of blood was created on the ground from how much blood Rex is coughing, any more soul extracted he would've died just like the system said. But after wiping the blood smeared on his mouth, Rex glances at Agatha once again.

"Why...?"

Freezing for a brief moment, Agatha then sighs, "Promise me you would leave after I answer!"

"Fine, I promise I would leave immediately after you answered my question. You have my word...", Rex replied uncomfortably, he never once thought that he would make a promise to a Supernatural, especially a Werewolf.

Upon hearing this, Agatha frowns, "Your word...? Is this the human way of promising?"

"Yes, it's similar to you swearing upon your Origin. Unbreakable"

"Fine, I'll trust you", Agatha replied with a sigh, but when it was her turn to answer she suddenly looks down feeling embarrassed but Rex already made a promise so she must answer his question. Not much time too, Dabigor is surely searching for her right now.

After a brief pause, she finally opens her mouth, "I'm quite embarrassed saying this. My family would be disappointed in me if they heard me saying this, but the war... I don't think that it's right"

"Back then the human race is horrifying, they were very strong, even stronger than the Origin", Agatha looks to be ashamed when saying this, she paused for a second before she then continued, "They view themselves as the supreme race while other races are inferior, and the ones that aren't humanoid-looking are considered as livestock. But that's back before we got sealed.  I d-don't agree with war, I heard that humans tried to negotiate with us but we're not listening and started the war. Humans negotiating shows that they're not like they once were, right...? But now everything is too late, I get why everybody is mad but we might just destroy the possibility of getting a peaceful Era..."

Unconditionally, Agatha shed a tear upon saying this.

But realizing that she was talking with Rex, she immediately wiped the tears before she added, "Because of that I tried to be kind to humans, at least right now, to you. I just hope that I can bring some impact even if it's small. At the very least, I hope you're not going to completely hate the Supernaturals"

Rex was frozen in his place upon hearing what Agatha just said to him briefly.

Despite not getting the full story of her life that he was so interested in for some reason, he can feel the emotions inside of her through her tone. More than that, Rex felt a throbbing pain in his heart seeing the bright smile Agatha is wearing right now.

It's been so long since he saw such a pure and innocent smile.

Ever since he lost Dinda in the military his lives are filled with blood and death, he lives a very harsh life where there's no room for softness in him and the people that he interacted with. Others might get the chance to let loose once in a while, but not him.

At the top of his head, the last time he had genuine calm was during his birthday.

'Maybe I was wrong...'

'When she said it like that, humans back then are definitely very evil. From what I heard about these ancient humans, they were really arrogant... maybe I'm too one-sided right now and fail to look from both sides', Rex thought contemplating the world.

Clenching his jaw tightly, Rex takes one last look at Agatha.

Something so pure shouldn't come from a Supernatural if he's going with how he thought before, and yet here she is, standing in front of him while also emitting the same purity as Dinda despite being a Werewolf.

"Now, leave... don't throw your life here", Agatha said demandingly.

Even though he was still dazed by how the plan of kidnapping Agatha turned out like this, Rex's body moved on its own forcing a nod intending to leave as he promised to her earlier.

But when he was about to signal to Flunra to leave, he sensed something.

"Prince! Watch out!!"

From the side, Rex hears Flunra calling out to him and he also realized that an ominous feeling can be felt from the back, without needing to look he already knows that it was Dabigor that said to search for Agatha if she doesn't come back in ten minutes.

Maybe because his mind is currently in a mess that he was caught off guard like this.

Rex forces his body to turn around quickly showing his extremely fast reflex, but Dabigor is also a fast attacker. When he's halfway in rotating his body he can already see Dabigor's claws are a few inches away from him.

But not making any rookie mistake, Flunra created a rune in the void using his blood.

It was the circle-shaped rune stacked with the symbol of a cross and infinity, the same rune that he created back then to protect Zegrath by materializing a red barrier that is very sturdy beyond measure.

Even Rex needs to use everything he got just to pierce through the red barrier.

'Hmph! I live thousands of years longer than you boy, you can't penetrate the red barrier', Flunra snorted inwardly, his movement is very fast and he was also confident in the rune he just made. A rune designated to defend a Prince.

Grand Aegis Rune, the power of the rune resonates with the Prince that is targeted.

Since he's in his human form Rex's power is equivalent to an early ninth-rank realm, the Grand Aegies Rune can mimic that but Flunra's blood is not enough to fuel the rune. At the very best the barrier would be equivalent to an eight-rank realm.

Dabigor despite his fierceness was nothing but a peak seventh-rank Werewolf, he has no chance.

Just like Flunra, Rex is also confident as he didn't need to be worried by a seventh-rank Werewolf. Even without Flunra's help, his bare skin would be able to block Dabigor's claws, it's nothing for him.

But when the claws were about to connect with the red barrier, something unexpected happen.

"Activate!"

Swoosh!

With nothing but a small chant from Dabigor, a dark blue mark appears on his forehead. Rex's eyes almost popped out of their sockets upon seeing the mark, 'What in the world... K-King Mark?!', he exclaimed inside his head.

Even Flunra was caught off guard by this, he didn't expect this turn of events at all.

Upon finding that Rex was caught off guard by the mark on his forehead, Dabigor exposes his brutal joker smile showing his razor-sharp teeth before his claws start to glow with dark blue energy.

Crash!

Almost as if the red barrier was made of regular glass, it shattered instantly.

Rex can feel his senses are giving him a danger signal which makes him instantly activate his Red Force and Pure Brace of Moonlight skill, he also activates his Alpha Bearing knowing that it will probably work on Dabigor.

But since the claws are an inch away, only his Pure Brace of Moonlight is fast enough to be active.

Stab!!

"Kaahhk!", Blood gushed out from Rex's mouth.

Even with the Alpha Bearing that weakens Dabigor and also the Pure Brace of Moonlight skill that strengthens him, the claws covered with dark blue energy pierced his chest but stopped from getting in further because of Rex grabbing Dabigor's arm.

Gritting his bloodied teeth with his eyes glowing purple, Rex glares at Dabigor angrily.

"Human... are you lost here?", Dabigor asks with a scornful grin.

Rex elongates his human fangs into Werewolf fangs before he growled at Dabigor back, and this surprises Dabigor but his expression turns neutral again, "Alpha Werewolf from the human territory, and also a Prince I see... Pleasure meeting with you"

"Uncle stop!! Don't kill him!", Agatha shouted from the back but got ignored.

Knowing that there's no reasoning with such a brutal Werewolf, Rex cloaks his entire body with Red Force before propelling himself back by kicking Dabigor's chest. Blood gushed out of his wounded chest as he landed a couple of steps behind Agatha.

Not long after that, Flunra appeared beside Rex feeling ashamed from getting taken by surprise.

But Rex didn't blame Flunra knowing that it was out of both of their expectations, "Since when does King Mark become common? I thought King Baralt is the only Werewolf that has King Mark", Rex asks Flunra whisperingly.

"That's not King Mark, I never expected King Baralt has already reached this power...", Flunra frowns.

Upon hearing what Flunra just said he realized that the mark that Rex thought was King Mark is different, it's not shaped like a full moon but half a full moon instead. And it's glowing with dark blue light.

"What is it?"

"It's the Herald Mark... When a Werewolf that possesses King Mark steps into the next realm of ascension, they will gain the ability to bestow power to other Werewolves. From the looks of it, King Baralt has reached the first ascension of the Super Moon..."

Rex shifted his eyes back to Dabigor in alert upon hearing this.

With him and Flunra being in the Werewolf territory, activating King Mark would be a very foolish move. King Baralt might come if he did that and on top of that, the neighboring Vampire King might also come.

For now, Rex can only stick with his human form, he then decided to check on Dabigor's stats.

'It's not a joke, this Herald Mark makes him way more powerful than before...'
