The Invincible Full-Moon System

An unbelievable sight was presented before Mavenna.

In the last five minutes of watching Calidora engaging against the berserk Rex who has his power soaring terrifyingly, Mavenna managed to see the full might of the Royal Black Prince as Rex activated both of his King Marks instinctively.

His power was the stuff of legends in the entire history of Werewolves.

Mavenna had never seen a Werewolf making use of two King Marks during a fight like this.

Normal Werewolves would never have the chance to have two King Marks.

Additionally, even if a normal Werewolf acquired two King Marks, they would experience an energy overload, resulting in their bodies collapsing entirely. It would be fatal for them, but the Royal Black Prince would have no problem handling this.

Since their physiology is designed for this, containing multiple King Marks is their forte.

Other than that, she also got an unexpected surprise.

Calidora has shown to possess a remarkable power of dark revival. Each time Rex managed to cut her down, she effortlessly rose again, wearing the same maniacal smile. It was an unnatural and formidable ability, one that a Vampire shouldn't have.

Looking at Rex's ability feels like looking at the last kind of an animal.

Differing from that, looking at Calidora's ability feels like looking at a new terrifying animal.

Tonight is definitely one of the most shocking nights in Mavenna's life.

Crash!

Just then, Mavenna was abruptly snapped from her trance as Calidora collided with the wall beside the door. A glance revealed the utterly gruesome sight of Calidora's headless body sliding against the wall, blood spraying in all directions.

However, like before, her head started regenerating at a rapid pace.

Upon closer inspection, Mavenna now sensed the odd bronze energy that was healing her.

'A curse? She also cultivated in the way of witches?' She pondered in shock.

Much like becoming an Awakened, which requires an affinity to a certain element and is quite rare amongst normal humans, the path of becoming a witch unfolds along similar paths. Only those who have a cursed source is able to become a witch.

Having an affinity to an element is more common than having a cursed source.

In the ranks of Vampires, it was even rarer.

So seeing Calidora able to cultivate her cursed source to this degree is quite shocking.

Judging from her ability, she must have a very strong curse too.

Manipulating the essence of her own blood energy, Calidora stood up without a physical gesture, hovering defiantly as her gaze locked onto Rex again. His fury intensified as he realized that he couldn't kill Calidora for good.

For him, Calidora is like a cockroach that refuses to die no matter how much he tries.

"I'm uncertain about the nature of your ability, but if you're using your curse for this revival ability, I suggest not doing it too much. Excessive use of that may weaken your cursed source" Mavenna cautioned from the side, seeing that Calidora had no intention of stopping.

Mavenna couldn't understand why Calidora wanted to engage in a fight with him like this.

If she did it out of fun, then at least pick a better time.

Going against Rex right now, fueled with the zenith of the Hare Moon when he's already so strong already, is really foolish. Any attempt she threw at him would undoubtedly fail, she wouldn't even be able to scratch him.

Upon hearing this, Calidora clicked her tongue, "Shut up, old hag. No one is asking you!"

'Nobody is listening to me, I wonder why...' Mavenna rolled her eyes.

Despite her benevolent attempts to caution Rex against meeting with Gistella, he paid no heed and fell into the Executor's trap. Now, she sought to warn Calidora, who had ties to Rex, but her advice was met with another refusal.

Sighing to herself, Mavenna turned to leave and closed the door behind her.

Mavenna doesn't need to worry about anything.

No matter what Calidora tries inside, it would be futile, she won't be able to do anything to Rex in his state. Moreover, having already been defeated by Calidora and was too late in helping Rex, Mavenna found herself powerless in the current situation.

It was already too late ever since she fell asleep earlier.

'Thankfully, I'm not Sir Rex's Luna. If I were her, my soul would've left my body after learning about this, and that's not fun at all' Mavenna pondered with a shake of her head, imagining to be in the Luna's shoes made her shiver.

But then again, she's not, so she doesn't need to think about that.

She decided to return to the bed chamber, coursing through the empty and dark hallway.

'Hmm... Should I go back to the Demon Kingdom?' Mavenna thought, rubbing her chin in contemplation. 'Probably not. Elder Tilrith would've overworked me, so I'll just see where fate brings me, yes... that's what I'll do'

Just like that, Mavenna returned back to the bed chamber.

Unperturbed by the violent tremors caused by the prolonged battle between Calidora and Rex within the underground chamber, she chose to return to the dreamland instantly after reaching back to the bed chamber, mirroring her earlier tranquility.

On the other hand, the intense battle remained until the first streak of dawn.

A moment later.

Despite being inside an underground chamber of a castle, the morning was still able to whisper its arrival. Through the thick stone walls, there was a deceptive sense of dawn in the air, disturbing the slumber of a man lying in the center of the chamber.

Gradually, the underground chamber started to be illuminated with a bit of light.

Filtered light through unseen crevices.

Under this collective disturbance, Rex's eyelids started to tremble softly.

It took another minute before he slowly regained his consciousness and opened his eyes.

Blinking reflexively, he acclimated to his surroundings and discovered himself lying inside an expansive chamber, its unfamiliarity puzzling him. He was not in his Werewolf form anymore, so the Hare Moon must've ended already.

"Where am I...?" He uttered and slowly sat up with his hand on his throbbing head.

Nothing seems to make sense to him.

His mind is currently being blocked by a fog, and he felt drowsy and exhausted despite only just waking up. Trying to remember what had happened, he vaguely remembered lying on the bed before Calidora also climbed onto him.

When she leaned down to start the feeding process, everything became black.

Rex couldn't remember what happened after that.

Seeing now that he was inside the underground chamber, he must've moved here after the feeding process was done. But he felt uneasy as he didn't remember going down here, and he instinctively touched his neck.

'Right... The wound is probably healed already' He pondered with a wry smile.

Taking another minute to recollect himself, he took a deep breath and scanned the chamber.

In his astonishment, he observed that the chamber's walls were saturated with a deep red liquid, unmistakably blood, as the pervasive scent of it filled the entire chamber. However, he discerned that it wasn't all his blood, as he was well acquainted with the distinct aroma of his own blood.

Being wounded almost daily, the scent of his own blood is ingrained in his mind already.

Rex reckoned that his blood scent was dominated by another scent.

Did Calidora bring me here? Her blood is all over the walls.

A sense of realization came to him. Unable to remember what had happened after Calidora leaned to him meant that he went berserk, and through impossible odds, Calidora somehow managed to bring him here.

Naturally, she must've been wounded severely in the process, and that's not good.

System, can you tell me what happened last night?

<Negative>

<All features are suspended until the conclusion of the System Relaying Bet Quest>

Having read the notifications, Rex let out a big sigh, realizing he had forgotten about this particular matter. Determined, he pushed himself to his feet and strode out, with the intention of seeking out Mavenna to inquire if she was aware of what happened last night.

Reaching outside, he made his way back to the bed chamber that he was assigned to.

Last he remembered, Mavenna was sleeping soundly.

It was also because of her that he went to Calidora alone, which is quite dangerous.

She was the one who offered.

Remembering how reckless she could be when she was the one who offered to accompany him to meet with Calidora but ended up falling asleep, he could only shake his head and hastened his pace to the bed chamber.

Arriving there, he was speechless as he found Mavenna sleeping on the bed.

This girl... Is she the sleeping Demoness? 

Looking at Mavenna still sleeping soundly even though she slept early and was now already dawn, Rex could feel his countenance twitching, rendered speechless by how nonchalant Mavenna could be inside a castle that she was not familiar with.

Since her position moved, she must've woke up and instantly headed back to sleep.

Despite he was standing right by her, she didn't react.

Rex was fearful of how relaxed she was. If it was him, much less someone standing directly beside him while he was sleeping, he would have undoubtedly roused at the faintest hint of someone nearing his chambers.

Even if that someone didn't eventually enter the chamber.

Finding no purpose in asking her about what had happened last night, seeing her sleeping like a log without a care in the world, he decided to head out once again. He would need to check on Calidora, to make sure that she was indeed okay.

Knowing the Eternal Curse, he was not that worried.

He walked through the hallway and stumbled upon a particular section of the castle.

It should have been a drawing room, judging from the antiques.

But it was completely dark.

Not that there were no windows, but all of them were covered by thick blood energy.

He was attracted to this room because Calidora's scent was inside.

"Calidora, are you here?" Rex asked with a loud tone, announcing his presence clearly.

Although he could see through the darkness, he couldn't find her anywhere which was quite weird since her scent was obviously here. But after saying that, he felt some movement from above which prompted him to tilt his head up.

On the ceiling, he found Calidora sitting upside down.

Calidora seemed to be meditating in the darkness, undisturbed by the slow rise of the sun.

However, Rex realized there were some changes in her.

Did she get stronger again? Or am I thinking too much? But what's with these changes?

Strangely enough, her form emitted an otherworldly glow in the darkness, an unusual luminosity for a Vampire who revels in hunting in the night. Adding to the peculiarity, Rex noticed a set of diminutive bat-like wings near her waist, which she clearly didn't have before.

It must not be nothing if her form changed like this.

Rex, once again, cursed inside his head as if he had the System, he wouldn't be in the dark.

He could scan Calidora right now, but he obviously can't right now.

"Do you need blood for breakfast or something?" Rex asked, offering to give her blood.

Now that he's here, he would need to be on Calidora's good side as he would be asking for help with his cursed source right after this. In response to his question, Calidora jumped down from the ceiling.

Landing graciously in front of Rex, she raised her eyes which were now the normal violet.

"Hmm... No, I'm not in the mood" She replied casually.

Upon hearing this, Rex knitted his eyebrows together weirdly. He had never seen a Vampire refusing blood. Moreover, this was Calidora he was talking to, she was usually crazy about his blood but it seems today is not her day.

Calidora seemed to be in a bad mood, and her expression also showed that.

Like a woman in her period to be exact.

Finding that Rex was being awkward, not knowing what to do to return Calidora to her good mood before asking for her help, she intervened, "I know that you want me to do something. Just tell me, and I'll gladly help you. Alas, that's one of the reasons you decided to stay here with me, right?"

"Ask away, I'm all ears" She continued, blooming a weak smile on her face.
