The Invincible Full-Moon System

It came unexpectedly, spreading a warm sensation in his chest.

Looking at the beast core inside the mutated animal's chest, Rex noticed that it was gushing with torrential energy because of the disturbance from Kyran's earlier attack. Even then—his attack didn't possess enough power to crack the core.

Rex would need to be the one to do the attack to properly shatter it.

However, it was quite surprising that Kyran was able to penetrate the mutated animal's skin.

His mastery over energy concentration allowed him to do that.

I need to somehow pin this tail or else I'm going to be stuck here for the rest of the battle.

Just like the mutated animal's stats state—the tail is one of its danger zones as it could move at lightning speed—and deal lethal blows to anyone it touches. Casualties would climb, if Rex let go of this tail that was attempting to break free from his grasp.

Turning his left hand into claws, his eyes flashed fiercely as he slashed at the long tail.

Clang!

Despite enhancing his claws with the Unholy Claws of the Reaper skill—it barely left a scar.

But he knew that his attack was working because the tail became even more frantic.

Sparing no mercy, he began hacking multiple times ruthlessly.

Rex was intent on cutting the long tail off and starting from there—however—that was easier said than done as the tail burned with fire in retaliation, forcing a hiss out of his mouth. It was akin to him holding a burning lasso, and his skin was peeling visibly.

Gritting his teeth, a tattoo slowly formed on the back of his hand, "Sekhmet Tattoo!"

An old skill of his that he bought to fight Kevin back at Faraday University.

It provided him with more fire resistance which would hopefully help him in this situation.

However, as the burning sensation lessened, it came right back as the tail blazes with flames—destroying the Sekhmet Tattoo. Rex looked at his arm and the side of his body—and found that his skin was already burnt, displaying his muscle tissues and nearing to hit his bones.

Since he was not in his Werewolf form, his regeneration ability was being overwhelmed.

Damn it! System, use Skill Upgrades to upgrade the Sekhmet Tattoo skill!

<Affirmative.>

<It costs 10 Skill Upgrades to upgrade the Sekhmet Tattoo, does the user want to proceed?>

Yes! Just do it!

<The Sekhmet Tattoo skill has two paths of upgrade, which one...>

Whichever one could increase my fire resistance! Just upgrade it now!

<Congratulations, the Sekhmet Tattoo has been upgraded to Sekhmet True Tattoo!>

A description of the skill appeared after that notification, but Rex didn't even give some time to read it and instantly cast the new upgraded skill. Upon chanting the skill, the same tattoo, appeared on the back of his hand.

But this time, the tattoo wasn't only magically formed—it was created by an invisible hand.

As if Sekhmet herself had drawn the tattoo on the back of his hand.

Rex's body ignited in flames—an ancient and mystic flame, a fiery aura matching the intense heat of the mutated animal's inferno. However—despite the skill's efforts the burning inferno was only toned down to a slightly tolerable level for him, its heat was inextinguishable.

It was a testament to the overwhelming power of the mutated animal's fire.

Even Adhara, who was still fighting alongside the others could feel the burn of the flame.

If she was burning, then there's no doubt the flame is extremely lethal.

However, the effect of the skill is enough for Rex to utilize his black lightning power, forming multiple lightning rapiers, that he plunged along the length of the tail. A ferocious growl was unleashed as the mutated animal wailed, its tail impaled and firmly pinned to the ground.

Not enough.

Despite the rapiers, amplified with his lightning and red force, it was not enough.

Sensing what was happening, Kyran rolled back and used his bloodline powers.

Crack!

Crack!

Swish!

Countless devastating ice spikes that were enhanced with his dark elements stabbed the tail from the side, aiding in Rex to pin the tail on the ground. Similarly, Gelmar, who was watching this resolved had his midnight eyes becoming darker.

It was clear that the mutated animal was a meter away from breakthrough the next realm.

Feeling the new strength from his evolution, he slammed both hands onto the ground.

Bam!

"Your Majesty!" He shouted, calling Rex upon doing this.

Rex glanced over his shoulder when he heard Gelmar's call, and in the next second, he came to notice a surge of energy coursing through the earth toward the tail. Knowing what Gelmar wanted, he quickly infused his lightning power into Gelmar's energy, reinforcing it.

Boom!

Suddenly, a big piece of silvery dark metal construct exploded from the ground.

A construct akin to a bear trap, but much bigger—and it clamped down on the tail viciously.

Roar!!

Frustrated by the small pests on playing with its tail, trapping it in an awkward position, the mutated animal spat out a torrent of spiraling flames from its gaping maw. Its size was able to engulf not only Rex, but also a huge chunk of guards standing behind—numbering in the hundreds.

Getting in the way, Flunra quickly created a formation of ancient runes.

"Kaarghk!"

He got scorched and thrown to the side with half of his body burnt, but he was successful in creating the formation, that greatly shrunk, the size of the torrent of flames. Following that—Adhara came and took on the torrent of flames with her own violet flames.

Boom!!

Even though the torrent of flames was weakened, it was still pushing Adhara back.

Not to mention, her hands were slowly being burnt by its raw power.

Rex was poised to intervene—but his attention was arrested by the sudden surge in Adhara's violet flames. Their intensity escalated to a degree that startled him. "Since when has her fire been this potent? Has she acquired a new spell?"

It was surprising to see considering that he hadn't given her anything to achieve this much.

Nevertheless, her flames began to overpower the torrent of flames.

As the torrent of flames surged—a purple hue, seeped into its fiery waves. Gritting her teeth, with determination, Adhara thrust her hands to the right, diverting the blaze in that direction, obliterating only trees in its path.

Upon doing that, she coughed a mouthful of blood and fell to one knee.

"Are you okay, Adhara?" Rex rushed to her, worried.

Raising her gaze to look at the mutated animal—with blood drizzling down the corner of her lips she waved her hand in dismissal, "Don't worry about me—I'm fine. Its fire is very strong, and I could only do that one more time, I think,"

Listening to this, Rex nodded and trained his eyes back to the mutated animal.

Squinting his eyes—he noticed that the mutated animal's chest was still robust.

Its core wasn't anywhere near injured.

"I should aim for that spot with my Brutal Impulse again," He mused inwardly with a firm nod.

Since the mutated animal dodged his Brutal Impulse, then it definitely felt threatened, so Rex was going to stick with that powerful skill of his for now. Despite feeling that one hit wouldn't be enough, multiple times at the same exact spot should do the trick.

Knowing what to do, Rex made his move again, "Kyran, Flunra, on me!"

Swoosh!

Despite activating the Primordial Step earlier, Rex noted that the speed increase, was only at 50%. It was due to his realization that he could dictate which steps were counted by the skill—nevertheless, the time limit remained at five minutes, and now only three minutes left.

After that time limit is reached, his speed and agility would return back to normal instantly.

Earlier, he only used one step, so he still has four more steps.

Now, with the mutated animal minutes away from breaking through, to the tenth-rank realm, Rex wasted no effort to go all out. He used a step and blitzed straight at the mutated animal—but the mutated animal could still see him and tried to swipe its claws.

Rex smirked as Kyran and Flunra came from the side, slapping the swipe off its trajectory.

It provides Rex the opportunity to land a Brutal Impulse directly on its chest.

Bam!!

Feeling the impending lethal strike, the mutated animal attempted to phase, but it didn't work this time, taking the full force of the blow squarely. A guttural growl escaped its mouth as the energy gush from the Brutal Impulse pierced through its chest and exploded out its back.

Before the mutated animal could do anything, Rex already blurred and made another step.

At 150% speed and agility boost, Rex's movement was blurry even in the eyes of the mutated animal. Meanwhile, Flunra and Kyran concentrated on restraining both of the creature's arms, striving to render them immobile.

Kaboom!!

Knowing that it was in trouble, the mutated animal's entire body bathed in flames again.

It rendered Flunra and Kyran at the mercy of the heat.

However, that didn't last long as Rex came in like a fighter jet, blasting another Brutal Impulse at the mutated animal's, exposed chest. Unlike the earlier strikes, this one was so strong that it sent the mutated animal stumbling a couple of steps back.

A big gash was left on the center of its chest, and there was a light crack on its core.

Surely, Rex's attack managed to pierce through.

"One more hit, I can destroy its core with one more fully charged, hit!" Rex announced.

Upon hearing this—the other guards, and captains began to cast their spells more vigorously—helping distract the mutated animal as much as they could. Joining in the battle directly—it would be impossible for them, so this is the only support they could give.

Roar!!

Making a desperate attempt, the mutated animal turned the battlefield into a sea of flames.

Eruptions of flames blasted the people above it randomly, killing many in the process.

Additionally, it crouched down and curled into a ball, protecting its chest area.

Rex would not make a clean shot if it was in that position, and Adhara knew that which made her instantly burned with rampaging violet flames, a mixture of mana and spirit energy. Then, she unleashed the violet serpent wrapped around her waist at the mutated animal.

"Pneuma Spell, Slithering Chains of Jealousy!"

Under her control, the violet fiery serpent made its way to the mutated animal.

Wrapping its sinuous body around the mutated anima's neck, the violet serpent swiftly coiled around its snout as well. Exhibiting powerful strength—it tugged at the creature's snout while Kyran and Flunra pulled on its arms.

Beating the odds, they managed to force the mutated animal out of its defensive posture.

Struggling, they knew they couldn't maintain their hold for much longer.

But that fleeting moment was enough for Rex to come in with his right arm bulging with veins—containing immense kingly energy. Despite his right arm, bleeding all over from abusing the Brutal Impulse, it was a simple fix for him.

Rex only needed to activate his Berserker's Curse skill that numbed him to the pain.

Not that he couldn't stand the pain—but the pain wavered his control over his kingly energy, which was greatly required in executing a perfect Brutal Impulse moon ability. However, with the aid of the Berserker's Curse skill, that was not a problem.

Piercing the wind at high velocity, Rex smirked, envisioning the mutated animal's demise.

"Brutal Impulse...! Hmpph!"

Grunting, he swung his right arm with all his might—fully intending to destroy the creature's core and stop it, from reaching the tenth-rank realm. However, bad luck struck when his fist was inches away from landing on its mark.

Crack!

Blitz!!

Rex looked up and saw a vicious lightning strike was heading his way.

Precisely, it was going to the mutated animal's way, but he was standing on its vicious path.

It struck faster than even Rex's speed, and he got hit by it directly.

Crash!

Despite his full resistance to lightning-based attack, this lightning—which was spat, by the world pierced through his immunity and slammed him into the ground before the explosion sent his body crashing away.

From sheer willpower, he managed to push himself off the ground and looked up.

Only then that he was met by another vicious shockwave.

"It managed to break through..."

BOOM!!
