The Invincible Full-Moon System

Both Adhara and Ugrok are Fire Elementalists.

A sudden change in mana level in the surroundings was detected by them instantly, and the fact that the change revolves around the mana content in the surroundings turning into fire mana makes it even more obvious to them.

It was a phenomenon that Adhara experienced for the first time.

Normally, an area contains a blend of mana in the air, and the environment will determine the prevalent mana type. For example, near a volcanic terrain, the concentration of fire mana would undeniably surpass the other elemental mana.

However, the presence of the Elemental was able to disrupt the mana concentration.

Almost as if it was the environment itself.

Just the presence of the ancient Elemental alone was able to turn other elemental mana into fire mana which shouldn't be possible. It was supposed to only be viable to the will of nature, but it seems the ancient Elemental itself acts as the extension of nature.

Making sure that her senses were not deceiving her, she summoned fire on her hand.

Swoosh!

Albeit she intended to summon a flicker, the fire that came out was blazing.

'So the Elemental truly embodies nature, enhancing the strength of Fire Elementalists in its proximity" Adhara pondered, her gaze quickly returning to the Fire Elemental, eyes ablaze with intense focus, staring straight at them.

Levitating above the red lake was the Fire Elemental.

It emerges as an awe-inspiring, infernal figure with fierce, billowing arms and a searing head. Its incandescent flames swirl and twist in a mesmerizing, relentless maelstrom of unbridled flame power, helping onlookers to easily identify it as a Fire Elemental.

Finding that the Fire Elemental said no words, Adhara decided to introduce herself.

"Greetings, I am Adhara Alpenore from the Silverstar Pack. I've come by your invitations" She announced loudly. Even though the Fire Elemental looked hostile, Adhara believed that when it knew who she was, then it would welcome her.

However, she was dead wrong as the Fire Elemental blazes even stronger.

Boom!

Swoosh!

Adhara and Ugrok had their eyes widen when a fire shockwave was heading towards them, it hit them like a truck, pushing them back strongly. Even though Adhara had already created a fire barrier to protect them, it was completely futile.

The fire shockwave passes through her barrier like a ghost through a wall.

It didn't make contact, ignoring Adhara's barrier.

Because of this, Adhara and Ugrok could only cross their arms to block the flame.

'I could feel the heat... ' Amidst the predicament, Adhara frowned. 'Even though I am a Fire Elementalist, my body was actually being scorched. It doesn't feel like being scorched by a Fire Elementalist above my realm either, it just feels different' 

Sensing this kind of sensation was surreal for her.

Due to reaching the eighth-rank realm, higher-ranked Fire Elementalists were scarce.

She never felt her violet fire was overwhelmed like this.

Knowing that this would end up badly if she didn't do anything, seeing that Ugrok was also struggling to block the heat of the fire that threatened to burn them to ash, Adhara quickly took out the arrowhead and raised it above her head.

Out of anything, this was the only thing she could do that came to mind.

Just as expected, when the arrowhead appeared, the shockwave of fire vanished instantly.

After the fire shockwave subsided, Adhara observed the lingering burn marks on her arms and body which were visibly healing. Lowering her hands, she noticed the once hostile air around the Fire Elemental had dissipated.

It seems the Fire Elemental had just realized that she was telling the truth.

Following that, the Fire Elemental hovered to the side of the lake and bent down to touch its surface, summoning a very intricate rune formation that surpassed the sophisticated rune construct of the teleportation formation within Dargena City.

Soon enough, the rune formation turned into a portal to a whole other world.

The Fire Elemental then turned to look at Adhara and Ugrok, signaling for them to get in.

Adhara and Ugrok exchanged a meaningful glance before striding purposefully toward the portal. As they navigated the floating rocks, they were near the portal and could clearly see what was waiting for them on the other side.

It was an underground fire canyon that seemed to be within the crust of the earth.

Despite their hesitance, the two jumped into the portal.

Landing firmly on the ground, the two quickly took a look around and were surprised at what they were seeing right now. Contrary to their expectations, the fiery underground canyon was more than a mere space within the crust of the earth.

Signs of civilization could be seen around the place.

Molten rivers of lava flowed in the surroundings, carving through obsidian rock. Amongst the tumultuous magma, surprisingly, there were iridescent pillars at the far front, housing some sort of platform of breathtaking sculpture, their colors shifting in the eerie glow.

Beauty and danger coexisted in a fiery spectacle.

This was the home of the Elementals, the home of the Fire Elementals.

The Fire Elemental they met before also swirls down before the portal closes once again.

Silently guided by the Fire Elemental, Adhara and Ugrok traversed the entire place. Words were left unspoken, and even if the Fire Elemental attempted to talk with them, their full attention was irrevocably drawn to the escalating astonishment the further they delved into this extraordinary place.

Other Fire Elementals could be seen, bathing in lava in peace.

All of them turned their heads to look at Adhara and Ugrok when they passed.

However, what shocked Adhara and Ugrok were in fact their forms.

Unlike the initial encounter with the rough humanoid Fire Elemental, the subsequent entities they encountered assumed the forms of various animals. Among them were creatures that resembled fiery lions, serpents, and a myriad of other animals.

One has even taken the form of a fish.

Additionally, there were even some that took the shape of a small cute ember of fire.

'Since I am a Fire Elementalist, I could tell that their powers differ. Out of all them that I saw along the way, the strongest one was this Fire Elemental who was guiding me. I think there was some sort of hierarchy that could be discerned through their forms' Adhara pondered.

Her observation made her assume that the strongest was the rough humanoid form.

Following that was the animal form before the small ember form.

It didn't take long before Adhara and Ugrok ascended the rocky staircase and reached the elevated platform that both had already seen from the distance. At its center lay a dynamic mechanical structure, a relic from the ancient past.

A hint at a technology long forgotten.

The Fire Elemental gestured for them to stay there before it moved to the side.

Anticipating what was going to happen, the mechanical structure at the center came to life with an unexpected animation. Its intricate layers began a synchronized dance, some moved clockwise while others countered the motion, producing a symphony of mechanical sounds.

Only then that a flicker of fire start appearing.

Under both of their eyes, the fire gained mass quickly and exploded into a vortex of flame.

Swoosh!

Keeping their eyes locked onto the spectacle, Adhara and Ugrok managed to somewhat see through the vortex that there was an entity, rising from the mechanical structure as if he was waking up from his slumber.

An entity that had a stark difference in form compared to the other Fire Elementals.

This entity looked more humanoid than the others.

Its aura also estimates that this Fire Elemental is the strongest out of all.

"A King...?" Adhara muttered out her guess as the vortex slowly grew and rose even higher.

When his eyes were fully opened, the vortex erupted, it splashed into the surroundings and revealed the entity's complete form. A humanoid figure emerged—a Fire Elemental adorned in deep red skin, equipped with a regal fiery cape and leg armor.

His bare torso showcased an intricate mark, resembling an ancient symbol.

Just the sheer heat from this entity was enough to spark Adhara's fire to life, almost as if her own fire had a mind of its own, wanting to come out to greet the entity of absolute fire before her who was now looking down at her and Ugrok.

"Are you Rex Silverstar...?" the entity asked with a dignified, astral tone.

Upon hearing this, Adhara shook her head, "I am Adhara, the Female Alpha of Rex's pack"

"I was hoping that Rex himself would come" the entity declared again.

However, Adhara disregarded his comment as nothing and raised the arrowhead, the sigil of Elemental once again, "Why have you sent your sigil to us, the Silverstar Pack? I have come here to inquire about your reason"

Obviously, she already had an assumption in mind.

Flunra told her that the Elementals might want to thank Rex for what he did.

"Reach your fire towards me..." the entity replied.

Albeit not expecting this, Adhara did as she was told and reached her violet fire towards him.

It was then that the entity touched the violet fire with his own fire.

Just the exact moment after that, Adhara's eyes widened as her flames were consumed by the entity's fire. As it enveloped her, her eyes ignited with a fiery intensity, and the power of the entity infiltrated her mind forcefully.

That happened so fast that Ugrok was too late to react to what the entity did.

"Adhara!" 

Ugrok growled in utter surprise before he quickly snapped out of his daze and turned towards the entity, his body burned with red force as an air of hostility shot towards the entity, the fact that the entity attacked Adhara right in front of him was unforgivable.

However, the entity quickly assured him, "Don't misunderstand, I didn't attack her..."

"I'm simply telling her a story, our story" He added.

Meanwhile, Adhara could feel a massive amount of information being shot into her brain.

She could see numerous flashes of memories that turned out to belong to the entity himself, showcasing what had transpired in the past. Before long, Adhara learned that what Flunra expected was true, he was right once again.

Inside these flashes of the past, Adhara could see a massive war between two factions.

A war between the Demons and the Fire Elementals.

Based on the information that she was injected with, in the past, the Demons were losing the fight against the Angels and were in dire need of more power. So, they turned their attention to the Fire Elementals, possessing the True Fire essence within them.

The Demons relentlessly attack the Fire Elementals, showing no mercy at all.

Hell was unleashed at the Fire Elementals' doorstep.

Its crawlers poured out like a black tide, pulsating with the cruelest malice imaginable, all sought to kill and maim as many Fire Elementals as possible, a gruesome sacrifice for the malevolent Demon Origin himself.

A fleeting moment is all it takes for the Fire Elementals to be taken down completely.

Casualties amounted to 90% of their entire population race.

Hundreds of millions fall.

By harnessing the essence of the slain Fire Elementals, the Demon Origin absorbed their power, transforming his Hellfire into the potent True Hellfire. In a symbiotic connection with the subordinate Demons, their power was also transmuted into True Hellfire.

It provided them a decisive advantage in the conflict against the Angels.

None of the other Elementals came to help as a move from them would cause political issues with other races. Thus, the Fire Elementals were mostly annihilated. Surviving Fire Elementals fleed as far as possible, to preserve their lives.

However, the Demons were all out of mercy and chased after them.

Surprisingly enough, one of the most vicious pursuers sent by the Demon Origin was none other than the faction of Demons that Rex has obliterated, the notorious and fearsome Rastrikan Demons.

A faction that was able to kill half of the survival Fire Elementals.

Demon Lord Kirgil savored the essences of the Fire Elementals and emerged stronger.

'Once again, Flunra was right. His knowledge and experiences are truly a blessing...' Adhara pondered silently, his usefulness proved Rex's foresight and intuition to be correct once again. It was the right move to turn him.
