The Invincible Full-Moon System

Rex tilts his head a little while still keeping his dark expression, he was truly on the verge of losing it on the inside but from the outside, he looks outright calm aside from his clear eyes filled with murderous intent.

Throughout his life, he always thought that watching his parents die in front of him was the worst.

It was a very painful moment in his life and even permanently traumatized him from the feeling of helplessness, he doesn't want to feel weak and helpless in a situation that really matters just like that particular night.

Now that he experienced this, he realized that he was completely wrong.

Although watching his parents die was something that many wouldn't be able to recover from, the fact that he has the absolute power to do something and make a change but was too late is a worse feeling than being helpless.

If he were here, nobody can't touch the strand of hair of his parents.

But God and fate played him by making him unaware of what his parents are going through, reality proves that he was not here to even try to do anything. It brings a more sense of frustration than actually not being able to do anything.

Giana steps back in fear, watching Rex and Sebrof staring at each other.

Not stopping at that, the fear clenched her heart so hard upon seeing Rex clenching his fists strongly. Even though she was just seeing them from the side, her neck feels tight as if those hands are choking her.

Many would find it surprising to see Giana's state right now.

Since both of them are basically at eye level, their stare-down is intense and choking.

Knowing that there's a big chance of not being able to explain or even say anything in this situation before a fight breaks out, Sebrof already went into his battle mode. Red lightning sparks and amasses before his aura exploded, ripping his shirt in the process.

Only the coat he wore earlier remains.

Swiftly, the red lightning element infiltrates his body and even cracks the skin all over his body.

With the rampaging spirit energy and also the red lightning element that of an Ultimate Element, it's clear that Sebrof is transforming into his Gladiator Form. It made his entire blood turns into red lightning, amplifying his physique to an otherworldly level of strength.

Sebrof's body is getting bigger, and he's now towering over Rex as he even needs to look down.

CRACK!!

Red lightning strikes descend from the sky before hitting Sebrof's entire body, finishing his transformation. Now he was akin to a lightning Demigod, his aura alone feels like swords drilling into the body.

On the back, Sebrof's aura takes a shape of a huge growling tiger made completely of lightning.

It was his spirit, Baikko the Aberrant Lightning Tiger.

Not many people have seen Sebrof's Gladiator Form ever since the Great Barricade Bloodbath, even many of the top ten of the Golden Crest Families haven't seen Sebrof's Gladiator Form yet but they all heard rumors about it.

A particular rumor that spreads around said that he has the strongest Gladiator Form.

Out of every ninth-rank realm Awakened under humanity's banner, Sebrof has the strongest Gladiator Form due to his spirit which is also amplified by an unknown treasure that he got. It was one of the reasons that he becomes the strongest person in the entire Ratmawati City.

"We do not need to fight, this is a misunderstanding", Sebrof mutters lightly.

But even under the suppressing force that even gives goosebumps to Giana on their side, Rex doesn't seem to be disturbed as he didn't even try to look up at Sebrof's eyes and kept his eye straight.

Upon hearing what Sebrof said, Rex's expression twitched, "Misunderstanding...?"

"How light of you to say that this is all just a simple misunderstanding, I think it's more than that"

Although he was doing a very good job in holding his unreadable expression, everything breaks when Rex heard what Sebrof just said. It was like gasoline to the fiery anger inside of him, and the fire finally burns every little sense he has left.

Enough is enough, it was already way out of the line.

Crack!

Rex's purple eyes glisten before the bone inside his body slowly readjusted in front of Sebrof's eyes, it was the first time for him to actually see something so bizarre like this. Something that shouldn't be allowed in this world.

Ink-black furs slowly come out and cover his body, and his mouth also slowly turns into a muzzle.

Despite already turning into his Werewolf form many times having already lost count, the transformation never becomes smooth as it's always the same painful process. It will never be smoother, he can only get used to the pain.

Slowly Rex's already muscular body becomes even bigger and his legs turn into hind legs.

Everything happens in front of Sebrof's wide eyes, his head started to change position from tilting down to looking at Rex until he needed to look up. With the Werewolf form, Rex is now even taller than Sebrof and also filled with sharp fangs.

Now Rex is the one looking down at him, even his horns are glowing with purple energy.

Both of their energies clash against each other and even made ripples in the space around them.

Sparks of red lightning that are coming out from Sebrof's body alongside the Kingly energy from Rex's body clash and turned into a gust of energies that deny each other, their clash of energy can even be felt for tens of miles away.

From afar, many of the citizens and Awakened can see two sky-high energies fighting each other.

Most of the people are starting to panic just from sensing the devastating clash of energy, and soon chaos ensued throughout many sectors of Ratmawati City. But the Awakened that are approaching the place to see what was going on were blocked by the UWO and SCO under the leadership of Vargas and the Black Messenger.

It was Sebrof's doing, he was not going to let anyone get hit by the collateral energy.

Rex's King Mark glows even brighter amplifying his presence, his eyes then bulged brutally before his entire body started trembling, "My intention was always very clear, I wanted to get rid of Supernaturals. I've helped humanity the best I can, but this is what I received. I've had enough of this bullshit"

With his animalistic eyes drilling into Sebrof's eyes, he then continued with a crooked expression.

"Maybe she's right, you don't deserve my help. Humanity doesn't deserve my help. Now that I've realized this, I'm going to kill each one of you...", he said with such a bone-chilling light tone that seeped into Sebrof's bones.

But despite his calmness, the system notifications went crazy.

<Super Berserk Quest has been initiated!>

<Processing...>

<A special condition has been met!>

<Chain Super Berserk Quest has been initiated from triggering another Super Berserk Quest before the reward from the previous Super Berserk Quest has been calculated and distributed yet!>

<Pain of Solitude!>

Satiate the user's thirst for blood that sparks from the death of the user's parents!

Quest Reward will be calculated by the amount of blood spilled to quench the user's bloodthirst and the reward would be merged with the previous Super Berserk Quest reward and tripled from triggering the Chain Super Berserk Quest.

Without even reading the Chain Super Berserk Quest, Rex made his move.

BAM!

Rex's claws move in the blink of an eye and clawed Sebrof from below using his Executor Slash skill, he sent Sebrof flying into the air and burst into the clouds from that attack alone. It was so sudden that it even bypass Sebrof's senses.

Bending his knees, he gathers strength in his legs before propelling himself to the sky.

Upon sensing the very quick projectile from below, Sebrof turns around before he raises both of his hands to the sky. Arcane red lightning mana gathers above him, sucking everything in the surroundings.

"Ultimate Arcane Spell, Eye of Red Lightning!!"

Blitz!!

From that brief chant, Sebrof created an actual eye of red lighting above his head.

After doing that he kicks the air with red lightning heading straight to Rex who is roaring as if he was possessed by the devil, he takes out his Amuerus Katana from the inventory while Sebrof created a saber made of red lightning in response.

CLANG!!

Their exchange was devastating as a powerful shockwave exploded in the sky.

Not only the shockwave but their clash created a thunderous sound that almost sounded like the entire sky is breaking, it was a thousand times louder than nature's lightning strike, stabbing the eardrums of the people that are too closer to their fight.

Sebrof's heart skipped a beat as his eyes widened when he saw the red lightning saber.

Even though he has perfected the Elemental Sword that he always used as a weapon, his red lightning saber shatters from exchanging a strike with the newly upgraded Amuerus Katana that is engraved with eight runes.

It's a weapon that even Flunra marvels at, thinking that the weapon is in Origin's Weapon realm.

Rex kicks the air swiftly with the Dark Moonlight energy before he lunges at Sebrof, he blurred and reaches Sebrof's back in a blink of an eye. But he was hit by a couple of red lightning strikes from the eye of storm Sebrof cast earlier.

Since it was an attack from a ninth-rank Awakened, Rex can feel his chest burning from that.

If he was any weaker than himself right now, his body would've been paralyzed by that but the Exalted Royal Black Werewolf bloodline neutralized the rampaging arcane red lightning mana. Rex recovers almost instantly from that attack.

The Eye of Red Lightning spell seems to be a defensive spell, zapping anything that comes close.

Gritting his teeth, remembering his mother's corpse once again, Rex glares at Sebrof.

"Extreme State!"

SWOOSH!

'He became faster!', Sebrof exclaimed in his head as he barely dodges a slash that threatens to slice his chest open, he was very wary about the Amuerus Katana that can even shatter his sword from a single hit.

Under the tension of the fight, they clashed in the sky like two falling stars.

Both of them burst through the clouds, their fight spreads across the sky as their movement was very quick and powerful. Not one of them intends to back down as they exchange hit after hit, this will definitely be a battle that will go on the history of Ratmawati City.

With their current power, their hits are strong enough to destroy anything they touch.

There is not one thing that they can't destroy with the ninth-rank realm power they got, even the ground would be obliterated but thankfully they were fighting in the sky, far away from most things.

From below, the sky looks rumbling with flashes of red lightning and dark energy.

Giana was looking up from below with cold sweat running down her neck, she was confused as to why Rex is attacking Sebrof instead of her which started everything and resulted in his parents' death. But it didn't take long for her to realize that Rex doesn't know yet.

It's clear that he mistakingly thought that Sebrof was the one that did this.

But even though she wanted to help Sebrof, the fear of Rex knowing the truth stunned her entire body. Giana can only watch from below without being able to move, 'I-I'm sorry Sebrof, but my body is not listening to me...'

Meanwhile, the fight continues fiercely.

Slash!

Sebrof leans his body to the side and dodges a slash from above.

Despite having a huge gap in their age, Rex and Sebrof seem to have the same amount of experience in fighting. Both of them are relentless and keeps on attacking each other's blind spot and protecting themselves perfectly.

In the heat of the fight, Rex started to become frustrated but his eyes then glisten sadistically.

Boom!

Rex and Sebrof clasp both of their hands together in a power struggle, their eyes are fixating on each other while their muscles are trembling to overpower the power from the other side, halting their destructive fight.

"We can still stop this! Rex, we're not enemies!!"

"Shut up, I don't care!!"

Upon saying that, Sebrof can feel Rex's strength climbing higher. It will overpower him in a bit.

'This is the worst scenario, his power will keep on rising the angrier he gets due to his bloodline as a Werewolf!', Sebrof gritted his teeth as he can feel he was about to lose this power struggle, he can't keep this up for long.

Sebrof kicked Rex back, freeing his hands before he conjured another red lightning saber.

"I can explain the situation and even give you the one that killed your parents, there's no need to fight! This is only going to weaken us for the Supernaturals, you out of all people should understand that!"

Despite his attempt, everything fell on deaf ears as Rex had already been engulfed in anger.

Rex clenched the Amuerus Katana tightly with his horns circulating more and more dark moonlight energy, "Don't put the blame on me... It was all of you that wanted to push me away, I've always been on Humanity's side!  I've sacrificed everything for humanity! I've devoted my sweat, my blood, my mind, and my entire LIFE!!"

"Did you really think that I did all of that JUST FOR MY MOTHER TO BE KILLED?!!"

Pointing at Sebrof that finds the situation is getting out of hand murderously, he waves his hand strongly before his entire aura exploded once again, dying the entire sky with a purple aura almost like an aurora.

Rex then clenched his trembling hand before he started chuckling with bulging eyes like a maniac.

Looking at his hands and body which are now covered in fur and muscles, showing that he was not human, he then continued, "Maybe I was the one in the wrong, maybe you're right, maybe... maybe I'm just another Supernatural!!"

SWOOSH!

Boasting his immeasurable speed, Rex dashed and resume the fight once again.

Knowing that he won't be able to convince Rex in this state, Sebrof immediately gathers his power, his spirit energy, and mana slowly becoming havoc. Sebrof then thrust the saber forward intending to stab Rex in the chest.

"Pneuma Spell! Total Lightning Thurst!!"

Upon seeing that the momentum brought Rex closer to his saber, Sebrof lowers his head nodding.

Even though the most favorable outcome would be Rex forgiving Giana, he knows that asking for that was too much. At the end of the day, Mrs. Greene died and that is an undeniable fact that wouldn't sit well with Rex.

But Sebrof had to try, he needs to find a solution to clean this absolute mess.

'I need to injure him enough to ease his anger...'

As Rex's body is getting closer and closer to the red lightning saber, he did something that made Sebrof's eyes enlarge in shock. Harnessing the power of a Supernatural, he reaches out his left hand to the red lightning saber and lets his hand get stabbed.

Stab!!

Cracking a sadistic grin, Rex finds an opening to land a powerful strike since Sebrof was surprised.

Gripping the red lighting saber's cross-guard with his left hand to force Sebrof to stay in place, Rex swung the Amuerus Katana in his right-hand cloaked with dark energy powerfully. It was a slash fueled by the anger inside of him.

Slash!

KABOOM!!

With no time to dodge, Sebrof got sent crashing to the ground, falling from the sky like a jet.

Sebrof got sent crashing down but not to sector 2 but to sector 3 instead, destroying dozens of buildings including sky-scrapers, and instantly trashing the whole place. Many screams can be heard as the buildings he hit topples over.

Total chaos ensued as hundreds if not thousands of people died from collateral damage.

Awakened that are nearby tries to help the citizen but their numbers were not as much as the regular people here, they can only save a handful while many more died from getting squashed by the rubbles.

From the crater on the ground, Sebrof stands back up before realizing he was on innocent grounds.

Boom!

But his attention was pulled again when Rex landed not far in front of him.

"REX SILVERSTAR!! WE CAN FIGHT ALL YOU WANT, DON'T BRING THE INNOCENT INTO THIS!!", Sebrof roared seeing the people in the surroundings that are crying, limping, and screaming. It was an unfortunate scene caused by a devastating blunder.

Upon hearing this, Rex looks down to the ground before his shoulders started to tremble.

Raising his gaze once more, he then said, "Innocent? Did you just say innocent...?"

With riling kingly energy swirling around his body, Rex growls and bares his fangs as his purple murderous eyes are glaring straight at Sebrof that is already starting to get angry, "My mother is innocent, but she died by your hypocritical hands. Tell me, is that fair...?"

Sebrof frowns as he finds this confusing, "My hands? I'm not the one th-"

"DON'T YOU LIE TO ME!!", Rex roared, cutting Sebrof's sentence short.

Looking to the people that are trying to escape from the place upon seeing that a Werewolf is attacking them, Rex shifted back to Sebrof and said, "If my mother is killed, then none of these people are innocent!! All of you suspect me just because I'm a Werewolf, turning a blind eye to everything I did for Humanity. If that's the case then maybe I'll go along with your suggestion..."

"Question of the day, what will Supernaturals do when they saw humans?"

"Rex! Don't you dare!!"

"Correct! They are going to massacre each of the humans they saw!!"

KABOOM!!
