The Invincible Full-Moon System

Chapter 1218: Be of Use to Me Still

Rex and Kyran gasped when the entrance to the warehouse was dragged open.

It reveals a sight the two had not anticipated at all.

Both had sensed the presence of Demon energy, but this was beyond their expectations.

Inside the warehouse—a couple dozen men could be seen scattered on the ground, cloaked in a pinkish energy. All of their mouths were slack, drooling, and their eyes were tainted with the same demonic pink hue.

Clearly, they were caught in some sort of pleasurable trance.

Both their aroused expressions and lower body state the obvious dreamy ensnarement.

Moreover, the air was thick with the sickly sweet scent of enchantment.

At the center of this bizarre mess was a Demoness—her tail swished excitedly from side to side and clung to a man who was just as enraptured as the others. Her wings—deceptively angelic in appearance, fluttered sensually as she reveled in her moment of pleasure.

Even as she embraced the man, covering his eyes with her fingers, she moaned alluringly.

From the looks of things, she was connected to the pleasure the man was feeling.

It was a scene of twisted ecstasy, the fond display of a Succubus.

Rex stood frozen at the threshold, taking in what he was seeing—but his gaze soon met with the Demoness—and her expression shifted from one of sheer indulgence to shock. Almost in an instant, the room fell into a tense silence, the only sound left was the soft moans.

For a moment, the Demoness, with her predatory grace locked eyes with Rex.

Her pleasure was replaced by awkwardness and a flicker of fear.

”What the heck...? How did you get here?!” Rex eventually exclaimed, surprised by the sight.

Not wanting to be confronted by this situation—the Demoness quickly turned into a pinkish phantom and tried to escape. She flapped her wings and went to the hole in the ceiling, the sight of Rex startled her, and she wanted nothing more than to get out of there.

But as she did that, a forceful force pulled on her wing and slammed her back down.

Kyran moved quickly, anticipating her attempt to escape and pull her down.

Boom!

Under the forceful impact, the floor cracked slightly and dust smoked the entire place.

However—the Demoness came out of the smoke crawling on her knees and headed to Rex, with a pair of watery, and pitiful eyes, ”Please—Rex, it is not what you think. I was not doing anything bad, I swear!” She said, rubbing her hands pleadingly.

Catching her addressing Rex lightly, Kyran landed right beside her violently.

He then grabbed her by the hair and yanked her head back, ”Do not address His Majesty so lightly, with that tongue of yours, Demoness...” He whispered—raspingly, baring his claws in preparation for ripping out her tongue.

Meeting Kyranʼs serious eyes, the Demoness gulped and looked at Rex for help.

Upon seeing this, Rex sighed, ”Let go of her, Kyran. Itʼs alright”

Giving the Demoness one last warning look, Kyran let go of her hair roughly and went away.

On the other hand, Rex could only massage his forehead in this situation.

”How are you here, Mavenna?” He eventually asked.

As it turns out, the Demoness is none other than Mavenna who somehow got into the city.

Holding onto Rexʼs leg out of fear of Kyran hurting her—Mavenna replied, ”I donʼt want to be worked to death, so I escaped again from Elder Tilrith and came here. I could easily squeeze myself inside, the people here are quite gullible, but I didnʼt hurt them I swear!”

Naturally, after the battle against the Fifthborn, Mavenna was picked up by Elder Tilrith.

For some reason, Elder Tilrith considers her as important.

Maybe Mavenna, having the Rosadonna Succubus bloodline has something to do with it.

”And this?” Rex pointed around at the scattered men.

All of them are Human, normal Humans, there are no Awakened amongst them.

Looking at the mess, she made—Mavenna quickly defended herself, ”I was bored, and asked around if anyone was willing to have a nice dream, and they all came here. Iʼm doing this only to kill time, nothing else”

”Really? Unless I become senile, donʼt you eat life force?” Rex asked, squinting his eyes.

Since she spent some time with Mavenna while preparing to fight the Fifthborn, he knew that she had a free soul—and also, liked to eat life forces. Considering the condition of the people here, he suspects that Mavenna also ate their life forces.

Mavenna panicked, she looked around with sweat all over her face.

But as she swept her gaze around, she met with Kyranʼs eyes filled with murderous intent.

He was standing beside Rex with his arm crossed, ready to pounce at her.

”I took a little, okay?!” Mavenna finally confessed, melting on the ground in fear. ”But itʼs not a permanent thing, I make sure to take very little, so that they would recover fine. Besides, I didnʼt force them to be here”

Upon hearing this, Rex sighed as this was not what he wanted to do.

”Who is she, Your Majesty?” Linthia asked from the side.

Rex glanced at her and replied, ”A Demoness that I rescued from the Fifthborn, and as if she hadnʼt learned her lesson—she ran away again from Elder Tilrith, and ended up here. Do you actually want to die, Mavenna?”

Scolded, Mavenna could only cross her arms and pouted, ”Iʼm not aiming to die,”

”I was only staying here because your city looked safe from Elder Tilrith,” She added lightly.

Looking at this, Kyran squinted his eyes and asked, ”What are you planning to do with her?”

Now that he took a closer look at Mavenna, he remembered her.

Back during the fight against the Fifthbornʼs forces he vaguely remembers the Demoness who followed Rex around—taking a support role, as he advanced. He didnʼt recognize her earlier, but now that he did, his killing intent dissipated.

Pondering for a moment, Rex decided to open the shop in search of something.

It didnʼt take long for him to find what he wanted and purchase them.

Nodding his head—Rex took out the Hell Pleasure Collar from the inventory before a burning collar manifested on his hand. At the sight of it, Mavenna tried to run away but Rex managed to seize her wing and stopped her from escaping.

Following that, he forcefully grabbed her chin and put the collar on her.

Unlike the usual collar, the Hell Pleasure Collar enveloped the entire section of her neck.

It was black in color with sharp designs and a pink pendant at the center.

As the collar gripped her neck tightly, Mavenna could feel that breathing become harder, and the hunger she felt, as a Succubus vanished instantly. She expected her power was sealed— but it doesnʼt seem to be the case.

”Get up,” Rex commanded with an authoritative tone.

Despite her unwillingness, his voice was akin to an irrefutable command to Mavennaʼs ears.

Unconsciously, Mavenna obeyed and asked, ”W- What are you doing to me?”

Responding with a light smirk—he took out the Mind Melt Reverse Tattoo from the inventory before he hit Mavennaʼs stomach, right above her intimate lips with his palm. It happened so suddenly, and it forced Mavenna to gasp deeply.

Swish!

It was then her eyes witnessed Rexʼs palm glowing brightly with a black light.

Following that glow was an intense burning sensation on her skin.

But that burning sensation wasnʼt long-lasting, it subsided as Rex withdrew his hand.

Mavenna looked down, and saw that the fabric where Rex had touched was now torn—giving direct access to her skin and revealing a magical tattoo, in the shape of a horned heart. It was a surprising sight, and she didnʼt know what this meant.

Still confused, her attention was pulled away from the tattoo when Rex raised his hand.

Rex still played a smirk on his lips, casting uneasiness to Mavennaʼs heart.

Eventually, he lightly flicked his fingers.

Click!

As soon as the flick echoed through the entire warehouse, Mavennaʼs eyes rolled back—and she collapsed instantly—to the ground. A surge of unprecedented pleasure coursed through her, overwhelming her womanly senses.

Mavenna drooled uncontrollably, her body convulsing in a series of intense orgasms.

Squirt!

She was feeling it so much that the floor beneath her was drenched in seconds.

Even her waist moved erratically, lifting and dropping in a maniac rhythm. Despite being quite a special Succubus—a creature of seduction of the flesh, and carnal delight—Mavenna found herself utterly unable to endure the overpowering ecstasy.

Her mind melted, lost to the sensation, and her body surrendered completely.

Additionally, her clothes began to dissolve, replaced by black and pink armor.

It only covers her private parts, leaving much of her skin exposed.

Linthia who saw this turned her blushed face away—she could not even begin to imagine on what Mavenna was feeling to make her completely lose it like this. Even Kyran was surprised—not expecting this sight.

On the other hand, Rex nodded his head, ”Sheʼll be more of a use if sheʼs obedient”

”Kyran, keep an eye on her until she finishes,” In a nonchalant manner—Rex turned away and walked out. ”After she finished, tell her to clean up this mess, and then bring her to me. Donʼt let her escape, not that she could escape in that state, but just in case”

Upon hearing this, Kyran snapped out of his daze and nodded his head.

Knowing Rex, he mustʼve had his reason for doing this.

As Rex walked out, however, he was smiling.

I know how useful Mavennaʼs power could be, and she can be of use to me still.

Sheʼs a Demoness, I bet she could help me turn Caraptaros.

Minutes later, Rex and the flustered Linthia arrived at a massive building.

Following his intention, he arrived at the supposed Vortex Pit of Elements infrastructure.

Before him stood a massive altar unleashing a breeze of mana, its grand structure dominated by a huge levitating purple crystal—hovering majestically above the altar. Its surface, flashed with intricate magical glyphs, pulsing with a mystical purple light.

Many guards were stationed to guard this place, considering this placeʼs value.

Approaching closer to the altar—Rex climbed on it and took a closer look at the crystal.

Inside the crystal was a torrent of elements, swirling and rotating like a furious tornado.

Each friction created by these elements against the crystalʼs walls produced a dazzling array of flashing colors. From this mesmerizing dance of light, and energy—a stone dropped down from the bottom of the crystal, the end product of the crystal.

Looking at the pile of Elemental Stones, Rex nodded his head firmly.

From a glance, there should be hundreds of them.

More importantly, all of them were high-rank while a couple were even higher than that.

”Is this all there is?” Rex asked while observing the elemental stones.

Upon hearing this—Linthia shook her head, ”Most of them are stored in a safe house, not too far from here—guarded tightly, all day around. From the report I got, this mine was producing about eighty to two hundred elemental stones per day”

As expected, it was quite a lot, but Rex was not satisfied with this.

System, can this Vortex Pit of Elements be upgraded?

Rex nodded his head, this will bolster the power of the Awakened of his forces.

But then, his gaze shifted to the neighboring land beside this altar.

It was an empty land that was perfect for him to place the Academy of Force Ethos, ”Hmm... I should place it in the south sector, as thatʼs a dedicated place for education—but I think here should also be fine”

Firming on his decision, Rex opened the control tab to settle on the place.

On the other hand, the onlookers were surprised to see the Emperor walking on the street.

As they were marveling at his presence, they were startled by a sudden light.

It came from right beside the Vortex Pit of Elements, a lunar light that climbed and began to shape, into a building. Naturally—Rex was already beginning to build, the Academy of Force Ethos despite the gazes he received from doing it.

”What is that towering light?”

”Itʼs His Majesty who is doing His Majestyʼs things”

”Doing His Majestyʼs things...? What do you mean by that?”

”Just like any damage done to the cityʼs buildings—it would be rebuilt, automatically. Under that pretense, His Majesty could also create a building, on a whim—but Iʼm really excited to see what it would be”

”Oh, is that so? His Majesty must be a God to be able to do this...”
