The Invincible Full-Moon System

Even though the three of them have gotten stronger thanks to their bloodline evolving into a higher-ranked one, they are still not strong enough to dwell inside the Humming Damned Forest freely as if it was any other forest.

Most of the mutated animals and cursed creatures in there can kill them easily.

From small snakes that can inject poison strong enough to topple over a powerful Awakened in a couple of minutes, cursed creatures that have different horrors to them, to the Mindless Vampires that although has been reduced, there are still some dwelling inside the thick forest.

In order to freely roam the forest, one needs to be at least in the seventh-rank realm.

Anything below that would be a complete suicide act as there's no chance they can survive inside the Humming Damned Forest for even a day, and this is why Gelmar was confused as to what Rex means by the castle and beyond.

Clearing the forest is out of their abilities. In the future they can, but now right now.

But the questions inside his head were answered when the entrance to the castle swung open revealing buildings poking their tip from beyond the castle, they seems to appear out of nowhere which is surprising to witness.

Not one of them expected this sight, it feels surreal, and yet it's right in front of their eyes.

"What kind of sorcery is this...?" Dindora mutters out of surprise.

Linthia also seems to be surprised as her mouth was opened wide, witnessing the tall buildings that are appearing beyond the castle. "Wow... is it really what I think it is?" She mutters, trying to grasp the situation.

As the three of them were surprised, Rex chuckled and walk past them.

Even though he seems nonchalant about the sight of the Moony Castle of the Lycaon King expanding beyond the castle itself, he was deeply surprised inside. It costs 10 million gold to expand the castle, and he already affirmed it to the system when he decided to go through with the investment.

Out of everything he bought from the system, this might be the most extravagant one.

Walking outside of the castle with slow and steady steps with both of his hands clasped behind his back, Rex walks through the bridge under the gaze of the other Supernaturals that are still inside the pit.

Glancing at Gelmar, Linthia, and Dindora who are all surprised, they become curious.

Since the group of Supernaturals was still inside the pit, they couldn't get a glimpse of anything from below. But they would soon be familiar with this sight as they are going to be the first ones to live there.

Rex walked over to the castle's wall and basked in the majestic view of the expansion.

<Moony Castle of the Lycaon King is undergoing expansion process...>

<Completion progress: 3%/100%>

<As the module of the Moony Castle of the Lycaon King revolves around the moonlight, the expansion will create medieval-style buildings that are powered with a formation that uses the moonlight as its source of power. It's also fitted according to the user's taste, making the interior of the buildings influenced by technological advancement achieved by humans>

Upon reading this, Rex can't help but smile as he nodded his head in acknowledgment.

Gazing beyond the castle's wall, his eyes bear witness to an entire city being built around the castle by a blue energy that does not contain any sort of energy that he has ever felt. It spans about two or three miles, creating literally everything from scratch.

It was beyond Rex's imagination. But then again, he should've expected this.

Just like when he bought the Moony Castle of the Lycaon King when he was first forced to live in the Supernatural territory, the same thing happened as the castle was being built in a matter of minutes from thin air.

Even though it's been quite a while since he has the system, its power still amazes him.

'I never thought about it, but there must be a creator of you, right? System?' Rex thought inside his head, there's no life inside the system and that makes it an object which means there must be a creator.

But then again, there's a chance that the system is actually a God in disguise.

Knowing the Lunirich Gods and even other Supernatural races and humans that have their Gods on their own, he started to think that maybe the Gods every race believed in is actually real.

It was nothing but a thought though, something that his amazed mind is wandering.

<The information the user wants is not able to be purchased through gold or other means, the only way to gain the answer to that question is by becoming the embodiment of Invincible itself and overcoming every entity that existed in the material realm>

Upon reading this, Rex was quite intrigued, he was not expecting the system to answer.

'It's true then, there really is a creator. Your creator must be an existence outside my realm...' Rex contemplated as he observed the expansion process that lies in front of him. Even throughout the hour-long process, he wasn't tired or bored, it always kept his attention until it was finally done.

<Expansion process has been finished!>

<Congratulation, the user has done the first investment for the user's future kingdom!>

<The One Who Rules achievement has been unlocked, and the user has obtained +10 Silverstar Pack member capacity, Kingdom of War Formation, and Servant of the Lunar Formation>

<Kingdom's Inhabitants number: 18>

A couple of notifications from the system appeared, but Rex's mind is somewhere else.

Gazing at the completed view of the expansion of the castle done by the system, the magnificent beauty of the sight nearly took his breath away. Everywhere his eyes rest, there are infrastructures of all shapes and sizes, from housing areas on the outskirts of the castle to bigger buildings resembling universities or shopping malls and bazaar places. It's a sight to behold.

It's a completely medieval city yet there's a modernistic edge added to the theme.

Coming from behind were Gelmar and the others that followed Rex to the top of the castle wall. Even though Rex didn't tell them to follow him, they did it anyway subconsciously, and they didn't regret it one bit.

Each of the city's parts is embedded into their minds, never to be forgotten.

Although the entire city looks empty and dead even though the sunlight illuminates every corner of the city, it was probably because there's nobody living in it and also there's no light coming from the buildings.

But that soon changed when Rex saw a spark of light from the city square at the center.

Swish!

Silver light travels through the crevices of the cobblestone ground of the entire city, sparkling brightly from below. 'It looks like somekind of formation...' Rex thought while witnessing this light.

It doesn't take long before the entire city was enveloped with this silver light.

Just then the buildings of the entire city were tainted with a silvery color and a vibrant glow, somehow the city becomes lively when this happens. But at this moment, a thought came to mind, "Dargena..." Rex mutters.

Upon hearing this light mutters, Dindora asked, "Dargena, what is that?"

Rex glanced at her briefly before he looks forward once again, "It's the name of this city, I'm going to name this city, Dargena. It means the Silver Pearl of the Moon..." he replied while nodding his head in affirmation.

The name suits this silvery city very well, he gains an epiphany while looking at the new city.

Not only was the color theme of the city silvery and the entire city is powered by the moonlight as per the system said, but the ruler of the city is also the Silverstar Pack which is a pack of Werewolves.

In Rex's opinion, the name is perfect and that's why he decided to name the city.

Squinting his eyes to the far edge of the newly made city, he finds that the expansion sacrificed a bit of the Humming Damned Forest. Most of the mutated animals and cursed creatures were surprised when they saw the forest was replaced by buildings.

But it ended with another wall, taller than the castle's wall that surrounded the entire city.

Due to this the mutated animals and the cursed creatures are trapped inside of the city, unable to get outside. Upon looking at this, Rex summoned Silver Eye from his inventory into his hand.

As Gelmar and the others are not strong yet, he decided to be the one to clear it.

"Pick any house to be your home, you can occupy it in the meantime. Also, familiarize yourself with the entire city, I want a full report of the city's landscape after I'm done with my closed-door training" Rex said while looking at the three.

With them around, there's no need for him to do mundane tasks as he needs to get stronger.

Upon hearing this, the three nodded their heads firmly as that is nothing compared to fighting the mutated animals and cursed creatures. Moreover, they are also given permission to enjoy such a vast city.

It's unknown what's everything inside the city, but they can expect great things.

Now that they witnessed a glimpse of Rex's power who is the one that is now their supposed owner, they can feel confident that nothing about him is less than their expectations. And that includes the entire city that he made.

"Yes, Lord Rex!" the three replied with a determined tone in a union.

Knowing that he would be gone for quite some time, he went over to the three and tap their foreheads with his index finger. In each tap, he forces them to absorb the high-rank affinity of their own elements.

Gelmar gained Wind affinity, Linthia got Mind affinity, and Dindora got Nature affinity.

Each of them already has their own magic affinities, but they were considered low-rank or middle-rank by the system thus Rex decided to upgrade their affinities. Moreover, he wave his hand before a couple of crystals appeared in their hands.

"Use that to train, get stronger so you can deal with these kinds of pests" Rex commanded.

Upon looking at the crystals in their hands that are sparkling and glittering with intense energy. The three widened their eyes realizing that these are high-grade elemental stones, something they would never gain access to if they stayed in their respective races' kingdoms.

High-grade elemental stones are only reserved for nobilities, not peasants like them.

On top of that, they also saw a couple that are bigger and more vibrant than the rest. Something that they have never seen before. Gelmar got Wind Stones while Dindora gained Wind, Earth, and Water stones, and Linthia gained Dark Stones.

Rex gives them knowing full well their affinities' capability that varies from each other.

Out of the three, Gelmar is the easiest one as he has wind affinity then he's given Wind Stones. Dindora on the other hand has nature affinity, she can use any elemental stones to get stronger and it's one of her perks, while Linthia can use Light or Dark stones. Rex is going to use the Light Stones so he gave her the dark ones.

"Serve me well, and one day you might be able to become one of the nobles in this city"

As the three of them shifted their attention back to Rex, they were stunned even more hearing those words, especially Gelmar. A fierce determination then flashes in their eyes as the three nodded their heads repeatedly.

It's a one-in-a-million chance for them to be taken by a generous lord such as Rex.

Not a single one of them is going to waste this opportunity that has fallen to their laps, they are going to do everything to seize it with their own motivation fueling them to be this determined.

Rex smiled when he look at their expressions before he turns to the front once again.

'Now, it's time to get rid of these mutated animals and cursed creatures before training. I kind of want to vent out some anger. Since these creatures volunteered, I'll just use them' Rex thought while cracking his knuckles, staring at the creatures inside the newly built city's wall.
