The Invincible Full-Moon System

Rex feels refreshed from teasing Adhara about the attack from the cursed creatures, and now they both are cuddling on the bed. With most of the things he can do now has been covered, he doesn't need to go anywhere except for training.

With his control over his mind being very high, Rex can meditate in any position he wants.

Even while he was lying down with Adhara snuggling on his arm, he was still meditating with his eyes closed. Adhara clearly needs some comfort, and by doing this he's basically killing two birds with one stone.

Hours passed, and his meditation was disturbed when someone knocks on the door.

Opening his eyes he glanced at the glazed window and find that it was already noon, and Adhara is still asleep despite the knocking sound which is surprising. 'She must've really been exhausted from fighting those cursed creatures' Rex thought while looking at her glittering sleeping face.

Adhara's sleeping face looks stunning, her face glowed even if there's no golden sunlight.

Caressing her head one time he then takes a deep breath before he gets up from bed gently not wanting to disturb Adhara's sleep, 'I wanted to tell her about the Herald Mark, but I ended up accompanying her sleep. I'll just tell her later' Rex thought wryly.

With that he heads to the door and opened it, Flunra is the one knocking on the door.

"It's the Dark Elves" Flunra said, informing the arrival of the Dark Elves.

Upon hearing this Rex nodded his head as the two of them made their way to the great hall and walks out of the castle, they head to the gate before the gate opens automatically through one thought from Rex's mind.

The castle is linked to him, he basically can control the entire castle in whatever he wants.

Right in front of the castle are dozens of Dark Elves almost reaching a hundred alongside many carriages bringing glowing stones, they are here to ship the elemental stones that are promised to Rex during the negotiation.

Going down from a royal wagon pulled by two mutated black panthers were three Dark Elves.

Out of the three Dark Elves, one of them is familiar to Rex, it was Naela, the female Dark Elf that was betrothed to Kyran. Not that it's already fixed, but Rex can't imagine Kyran refusing such a wonderful lady, especially when he's the one that wanted to ally with the Dark Elves.

"My apology for coming here too later, Silverstar Alpha..." a middle-aged Dark Elf bowed slightly.

Rex glanced at the Dark Elf that came out alongside Naela, he raises his eyebrows and replied, "I don't mind, the shipment is due today and there's still much left time before the end of the day." he paused before he points at the two middle-aged Dark Elves standing in front of Naela, "Are you Naela's parents?"

Upon hearing this, both Dark Elves smiled and nodded their heads.

"Forgive me for not introducing us first, I'm the head family of the Urithana Noble Family. My name is Fylson and beside me here" Fylson politely points at the Dark Elf beside him that resembles Naela greatly, "is my wife, Viessa" he introduced.

Viessa bowed elegantly by bending her knees a bit, "It's a pleasure to meet with you" she mutters.

Looking at the two Supernaturals who are giving him all smiles, Rex finds it hard to smile back at them but he managed to force out one, "No need for formalities, I come from a humble background. Calling me Rex is enough"

"I-I wouldn't dare..." Fylson replied with a wry smile, he can't afford to address Rex like that.

No matter what kind of background Rex has when he was weaker, he's now a ninth-rank realm entity that needs to be addressed with adoration and respect. Anything lesser than that would be offensive to his presence.

Flunra standing on the side then intervenes, seeing that Rex is not accustomed to this.

"Address him as Lord Rex, there's no need for you to address him by his position" he said, giving Fylson a way out which he eventually agreed. It's way more respectful to address Rex as Lord instead of just Rex.

Waving his hand to dismiss the topic, he points at the carriages, "Are these all of it?"

"Yes, it's 60% of our kingdom's elemental stone storage, each one of them is high-grade. Although we need it to trade with the Dwarves, winning Lord Rex to our side is way more important right now" Fylson answered while also looking at the carriages.

Rex mentally counted the carriages and finds them anywhere in the number forties.

Since he can't guarantee to betroth Naela to Kyran as he's his own man, King Jorik decided to give him 60% of the kingdom's elemental stones instead of the agreed 70%. Rex finds it fair, he doesn't want to force Kyran to do anything.

'I expected to be much more, but then again this should be more than enough' Rex thought.

Although the Dark Elves offered to bring the elemental stones inside and helped Rex store them somewhere, Rex declined and just told them to make them into one pile. Despite being confused, the Dark Elves did it anyway.

It didn't take long before a mountain of colorful elemental stones are piled in front of him.

While looking at the mountain of elemental stones that reaches quite high, Rex finds that there are not one lightning, light, and dark elemental stone. Most of them are wind elemental stones, the others are water, fire, and earth elemental stones.

Nodding his head, Rex touches the mountain of elemental stones.

As if there was an invisible force that teleported the elemental stones away, the mountain of elemental stones got reduced by half instantly. The Dark Elves that don't know that Rex has 'space' element power were surprised to see this.

But now knowing that, it's a fool for them to offer Rex their help.

<Calculating and converting elemental stones into gold...>

<Completed!>

<Obtained 160,000 Gold>

<Gold: 962,500>

Upon seeing the gold currently inside his pocket now, Rex frowned as it was not as much as he expected, 'I think gaining gold through elemental stone is really hard, using dollars is way easier compared to this' he thought with a sigh.

One high-grade elemental stone is only equal to one gold, that's a rip-off in Rex's opinion.

It doesn't compare even to the 100:1 ratio that the dollars have against gold, and in human territory, one high-grade elemental stone costs way more than $100. Saying that it's hard to get gold through elemental stones is an understatement.

Not wanting to dwell on this for too long, Rex turned around to look at the castle.

Gazing up at the Circling Sentinel that makes a shape of a blue Starfall rotating above the castle in a circle, Rex points the palm of his hand toward it and instructs something to it through his mind. Instantly after that, the Circling Sentinel shot toward him.

Fylson, Viessa, and Naela were surprised to see a blue Starfall heading toward them.

But Rex then said without looking at them, "Don't worry, it's not going to hurt you"

Swoosh!

Like a meteor falling from the sky, the Circling Sentinel hits the mountain of elemental stones that are still robust even though half of them have already been converted to gold by Rex. Soon, a blue hue envelops the entire elemental stones.

Under the gaze of the onlookers, the elemental stones started to turn into energy one by one.

Starting from the top the elemental stones started to burst into fragments of energy and supply it to the Circling Sentinel, and it didn't take long before another blue radiant stream shoot towards the castle.

<Moony Castle of the Lycaon King 1%/100%>

<4%/100%>

<11%/100%>

Rex watches as the experience bar of the castle started rising bit by bit.

Ever since he knows that the castle was attacked by the cursed creatures and Adhara got hurt by the fight between them, he was determined to make the castle stronger. One such way to make the castle stronger is to upgrade the castle.

By default, the castle only provides the ability to gather all kinds of energy into it.

Upon the first upgrade of the Moony Castle of the Lycaon King, the castle will gain two additional effects that strengthen the Circling Sentinel and the owner which is Rex himself. It's a good investment and worth the elemental stones.

It takes about ten minutes before the castle reaches the first upgrade.

<Congratulation, the Moony Castle of Lycaon King has reached the first upgrade>

<Master of Sanctuary and Circling Sentinel Upgrades has been unlocked! Please address the Moony Castle of the Lycaon King's features to complete the first upgrade!>

Rex reads through the notifications before he was presented with options.

<Please select the desired option:>

Soul Fragment Sentinel

Curse Fragment Sentinel

Magic Fragment Sentinel

While this is all happening the others only saw the entire castle sizzling with blue steaming energy, it covers the entire castle which was a sight to see. None of them know what Rex is doing, including Flunra.

Fylson glanced at Flunra asking what Rex is doing through his eyes, but Flunra shakes his head.

'Hmm... which one should I choose?' Rex thought, pondering the options.

These three options are connected with the Circling Sentinel Upgrades. At the current moment, the Circling Sentinel is only able to block physical attacks whether it is tangible or intangible. When the castle reaches its full potential, the Circling Sentinel can anticipate any kind of attack.

Magical attacks, soul attacks, or even curse attacks can all be intercepted by the Circling Sentinel.

As it is the first line of defense that comes before the barrier provided by the glowing crescent moon at the very top of the castle, being able to block essentially anything is a formidable first line of defense.

Rex then finally decided to choose curse, 'We're surrounded by cursed creatures, it's necessary...'

<Curse Fragment Sentinel has been selected, the upgrade will now commence>

Just after the last notification, the Circling Sentinel flew back and started circling above the castle once again. But it slowly split into two, becoming two Starfall. Not stopping at that, the two Starfall also transformed.

Slowly the two Starfall turns into a ghastly appearance of a drifting wolf, almost like wraiths.

Although the Circling Sentinel is not a living object, the form it takes right now makes it looks like it was alive. It's completely white like a ghost that is shaped like a wolf, but some parts like the veins on its head and also the eyes are red.

Overall, it looks quite scary to see, but that may be due to the fact Rex chose curse.

Now the Circling Sentinel can block cursed energy too, and the incident of the horde of cursed creatures attacking wouldn't be a problem right now. 'How strong of a curse can the Circling Sentinel can sustain right now?' Rex asked.

<At this form, it can block up to the ninth epiphany natural curse>

'Very high. With this, there should be no more cursed creatures problem' Rex thought and smiled.

Rex turns around to look at the others and finds them all looking at him with wide eyes, it must've been surreal for them to see something like that in the castle. It now doesn't emit the blue steaming energy like before.

But the castle surely got stronger, it's not evident but the others can feel it which is bizarre.

No castle should be able to get stronger like a living being, and yet they saw one right in front of them. It also belongs to a mysterious entity like Rex Silverstar, a Werewolf that has a human form. Everything about him is a mystery.

Without saying anything, Rex stored the rest of the elemental stones in the inventory.

Looking at the others with a nonchalant smile, he then said, "Send King Jorik my thanks for the elemental stones, I've put them to great use. Now that puts us to the last matter, Naela, right?"
