The Invincible Full-Moon System

It was very cold, the night wind was piercing her body, even though she was not a Werewolf.

While supporting Rex on her side to stand up properly, she scanned the place and she found that the two were at the end of a bridge, connecting to the castle's entrance with cliffs on either side, leading to the nothingness.

Aside from the Blood Bunyas, the air reeked with the scent of blood.

Just like what Rex said, they were in the Vampire territory, in front of an otherworldly castle.

Upon reaching closer to the entrance, Mavenna gazed up, finding that the ceiling was very high. Her body as a Succubus was way bigger, she stood around 6'2, but the ceiling easily reached ten or even twenty times her height.

Whoosh!

A group of bats suddenly descended from the ceiling, shrieking in high pitch.

"Can you tell me whose castle is this?" She asked.

Rex replied with a nonchalant shrug, "Even if I told you, you wouldn't know who she is"

Knowing exactly that Mavenna was not from the new era, or rather a recently awakened Succubus, she is probably foreign to the state of the world right now. He came to this conclusion when he saw her wings from earlier.

None of the Succubuses he met have wings like her.

Standing before the entrance, the two stopped before several glyphs glowed crimson.

Containing the knowledge from the dark depth of the Vampiric prowess, these glyphs shimmer lightly, almost as if welcoming them to the castle. Following that, the gate opened outwards slowly before the two finally walked inside.

Inside the hallway, it was completely dark.

But with their eyes as nocturnal creatures, it provides no obstruction for them.

While being supported as the pain wringing his mind severely, Rex saw that Mavenna had a deliberate small cut on her finger, leaving a trail of her own blood as a marker along their path, which was rather weird for her to do.

Rex looked at her and asked, "Why are you leaving a trail behind?"

"Hmm...? Oh— I don't know who the Vampire inside this place is, but I know that she has illusion abilities. I was only making sure to leave behind my scent so that we know the way out if it comes to it" Mavenna replied, answering as if it was natural for her to do this.

However, this only furthers the danger of ancient times.

For Mavenna to be this cautious, the time of her days should be filled with extreme danger.

Shaking his head, Rex replied, "I vouched for her, no need to be on guard"

Upon hearing this, Mavenna nodded her head, but she didn't lower her guard at all. Having learned of the legendary exploits of the anomaly Werewolf known as Rex Silverstar the moment she awakened, she recognized Rex's meticulous nature and understood that he was not someone to be taken lightly when even the Executor was scheming against him.

Many would find it assuring if Rex vouched for someone.

Not for Mavenna though.

Living in the cruelest and bloodiest dominion imaginable, she knew the unforeseen danger.

While it was reassuring that Rex vouched for the Vampire, the thought lingered that this seemingly trustworthy act could be a manipulation. Anticipating the potential danger of the Vampire deceiving Rex, she deemed it wise to maintain vigilance rather than growing more relaxed.

Soon comes the end of the hallway, another big gate, engraved with a big vampiric glyph.

It takes the shape of an inverted V letter with fangs and bat wings.

Upon sensing their arrival, the big gate was opened automatically with a fluid motion, and crimson water instantly seeped out from inside and brushed against their feet. 'Another illusion... the Vampire must possess the Eye of Phantasm, quite strong but manageable' Mavenna pondered.

Raising their gazes, the interior of the throne room greeted their eyes.

As opposed to the regal carpet that typically graced the throne room floor, this one is overflowed by a sea of ankle-length crimson water. Black fences constricted the path to the throne, and towering black metal pillars ascended like roots, gradually blossoming to the ceiling.

Grand stained glass windows, adorned with abstract drawings were placed around the room.

Finishing it off was a black chandelier, its candles burning with ethereal red fire.

Overall, Rex and Mavenna had never encountered a throne room quite like this. Typically, throne rooms adhered to a strict design protocol, each vying to rival the opulence of other Kings' throne rooms. However, this one didn't follow the norm, opting for a completely different aesthetic.

Soon, their eyes landed on the throne at the far center where a figure sat comfortably.

It was not a regular throne either, but a deep red single sofa.

Seated upon the throne with her hands laid on the handles strongly, the figure dominates the scene, her presence alone demands attention even though her upper half is shrouded in darkness. Her eyes were the only thing that could be seen about her, they were crimson with swirling black patterns.

No doubt that she is a Vampire, her blood aura is exposed to see.

'I should avoid directly looking at her eyes if it's really the Vampiric Eyes of Phantasm'

Not wanting to be influenced, Mavenna tilted her head down.

Rex, on the other hand, raised his gaze briefly before he lowered it again, finding that the pain in his mind becoming unbearable by the second. He would need to ask for a place for him to restrain himself in solitude.

With a gesture from the Vampire, the two approached the throne.

Each step splashed the crimson water.

"Hands off, Succubus..." the Vampire opened her mouth when the two got close enough.

Upon hearing this, Mavenna raised an eyebrow, "And who are you again?"

"Me?" replied the Vampire chillingly, leaning forward to emerge from the shadows. Her sinister vampiric countenance, marked by a hostile gaze, met Mavenna's eyes. "I'm not someone you'd wish to make an enemy of..."

Just as Rex expected, Mavenna didn't recognize the Vampire before her as someone familiar.

It was Calidora, and it was natural for Mavenna to not know her.

As opposed to making trouble for Rex, who was in dire need of help, and surely came here exactly for that, Mavenna chose to step back, allowing him to stand independently without her assistance in compliance with Calidora's command.

"For what reason do I have the honor of your presence here, Lord Rex..?" Calidora asked.

Mavenna frowned when she heard this.

Contrary to speaking to her, Calidora's voice was now refined, almost inviting to a degree.

'Do they have some history? No, it can't be. A Werewolf and a Vampire? It's simply not possible. But then again, what's with this alluring voice she's using?' Mavenna pondered, looking at Calidora suspiciously.

Pausing briefly, she then continued, "If I'm not mistaken, it's the Hare Full Moon outside"

"Even someone like you, a Royal Black Prince is not immune to its influence. I presumed you would be with your Luna and Female Alpha, especially considering your less-than-optimal condition, if I may speak candidly" She assessed Rex, her sweet gaze traveling from top to bottom, noting his evident distress.

Rex sighed, trying to stand upright, "You know why I'm here, it was you who planted the idea"

"Oh— Does that mean you're accepting my offer, staying with me until the matter regarding the Executor is over?" Calidora asked, her countenance remained calm, but the corner of her lips could be seen quivering, almost breaking into a smile that resorted her to covering her mouth with her hand with a natural movement.

Upon hearing this, Rex nodded firmly.

As it came to this already, there was no possible way that he could delay anything longer.

He would be a fool to not feel the urgency of finishing his plan with what the Executor had done to him. If he lost, then he would lose the System, and everything that he had built throughout the entire year, everything he had will be gone.

This includes the power he bestowed to the others, all of them will be retrieved.

Something like this is truly unacceptable, it was truly a devastating blow from the Executor.

"Yes, I'll be staying," Rex replied, his expression resolute and without hesitation. "I also want to express my thanks for what you did for me back then, when I went berserk. If you hadn't helped me through our connection, I don't know what I would have done"

Calidora cracked a smile, she wasn't expecting him to thank her personally.

'Excellent, truly excellent! I initially thought the Hare Moon would pose a hindrance, giving Evelyn the opportunity to sabotage my plan, but the fact that he's here instead of going back is a pleasant surprise indeed. I can't afford to mess this up' She contemplated within, striving to mask her bubbling excitement.

Even though she was usually good at this, it was hard to do this time.

It was an unbearably pleasant surprise.

She failed to anticipate the Hare Moon, but the stars suddenly aligned for her that night.

Positioning her legs better, seemingly rubbing her thighs slightly, Calidora's eyes glowed red before she proposed, "I'm willing to let you stay here, but as you might know already, nothing is free in this world. Do you know what I mean?"

However, right this instant, Mavenna tilted her head up with an obvious frown.

Not that she cared about what Calidora was saying, but she suddenly smelled an odd scent.

It took a moment for her to register what the scent was.

'Wait a minute, is she actually...?' Gazing at Calidora's thighs, her frown deepened.

For a brief moment, Calidora and Mavenna locked eyes, each wearing a peculiar expression as they assessed one another. But then, Calidora's gaze shifted to a stern intensity, seemingly giving a subtle but potent warning to Mavenna.

Only then that Mavenna realize that her assumption was correct.

'Even though I could stay clear of this, I couldn't stand by and do nothing' She pondered, glancing at Rex from the side who was oblivious to this. 'Just think of this as a thanks from me, Sir Rex. I'll help you out'

Rex then eventually asked, he would do anything, "What do you want from me?"

About fulfilling the necessary preparations for his plan, cultivating his cursed source, he couldn't do it the usual rough way. It required a more delicate approach. If Calidora wasn't willing, he couldn't force her, knowing she was as much of a lunatic as he was.

Due to that, he would comply with Calidora's demands, as long as it's not too much.

Smiling widely, she then answered, "I want your blood, and I want it this night"

"Come to my bed chamber after you settle down, and I'll drink your blood" She added.

Upon hearing this, Rex was surprised as the request was not that hard to do. If it's his blood, then he wouldn't have any problem with her taking some. Even if his blood was almost drained to the bottom, he wouldn't necessarily die.

He would probably only be forced to sleep by the System to recover faster, but that was it.

Just as he was about to agree, Mavenna intervened, "Can I come?"

"Succubus, I believe you are not a part of this. Who is she exactly, Lord Rex?" Calidora asked.

Instead of Rex answering, Mavenna answered the question herself, "I am indebted to Lord Rex, and is now his assistant. As for why I asked to come, it's because the Hare Moon is strong, and I would be able to help if the influence got too strong, and Lord Rex would try to land a hand on you"

"Good idea, fine, let her come, Calidora" Rex requested, finding that it was quite logical.

Since Mavenna is a Succubus, she could definitely help.

Calidora smiled in return, "If that's your wish, then so be it. Bringing her along won't be an issue. After all, I'm only interested in drinking your blood" She said with a hint of sarcasm. "However, I do have to warn you, Succubus, that when I'm drinking blood, I can be quite aggressive..."

"No problem, I can handle myself" Mavenna replied, also with a smile.

Despite Calidora's friendly demeanor, an undercurrent of murderous intent emanated from her, causing the air around her to vibrate to its rhythm. It could only be seen by Mavenna, who was the target of that murderous intent.

While Rex remained oblivious to what was happening, struggling against the Hare Moon.

'This Succubus, Mavenna... She's one annoying old hag'
