The Invincible Full-Moon System

Chapter 791 Ninth-Rank Realm Spirit Core

?

"If you use mind control on Delta, I'm not going to stay put" Rex suddenly said.

Delta was nothing short of very aggressive and hostile towards Calidora earlier, the sudden change in her behavior is concerning, and he suspected that Calidora did something to her and that's definitely not okay.

Upon hearing this, Calidora smiled acutely, "Do you have to threaten me all the time?"

"I'm not using any mind control spell on her. Maybe, she just knows that I have no bad intentions, have you considered that?" She added, stroking Delta's chin with her claws lovingly. "Stop being angry at me all the time, you're making me blush"

Rex can only sigh as he can't quite read what is in Calidora's mind at times.

Out of everything he knows about her, he's quite sure that she really wants to be with him for some unknown reason, that's clear enough for him. Maybe the Eternal Curse is to blame, but he's not quite sure.

"Can I ask you something?" Rex suddenly said, shiting his attention to her.

Calidora's eyes flickered from purple to red when she heard this, "Ask away, I'm right here"

"How did the Eternal Curse got triggered and bind us together? I vaguely remember that day when I tried to kidnap you, and I specifically remember that I gave you my blood. Is that what triggered the Eternal Curse?" Rex said, curious as to how the two of them got to this point.

It still puzzles him from then until now, he still doesn't know why the two of them got linked.

Rex doesn't know the history of Vampires and Werewolves. His understanding of curses is limited, but he does know that Natural Curses like the Eternal Curse can only be bestowed if they break the major law of nature.

Aside from giving Calidora his blood, he didn't remember anything substantial happening.

Upon hearing this, for a moment Calidora's cherry lips quivered, and no words came out of her mouth. Rex inspected her expression with a slight frown until she eventually turns her face to the side, "I don't know..."

'How obvious can she be? She's definitely lying' Rex thought inwardly.

But he has no intention of forcing it out of her.

Out of everything, Rex is already thankful enough that she's not hectic right now. It doesn't seem she would be frantic and maniacal as the last time she saw her, and that'll be best for her so that she didn't disturb his training. 

Since he can't let Calidora out of his sight, she has to be here with him.

Even though he learns that Calidora wasn't the one that killed Rosie in the first place, hence she even puts in the effort to stall for time, Rex still doesn't trust her being inside the castle freely as he didn't know her personally that much.

Aside from a maniacal, unhinged Vampire impression that he got, he know nothing about her.

Rex's view of her would probably not change that easily.

Continuing with his training, Rex stands up and stands at the center of the formation. Wiping the blood running down his nose, he takes out Giana's lightning spirit core and lets it levitates in front of with, coursing violent electricity to the entire room.

It's time that he reaches the ninth-rank realm, the realm of the highest for an Awakened.

Devo who was consolidating their spirit core and keeping 100% control over it came out of Rex's body, swallowing the entire room with thick mist and black lightning currents that blitzes here and there.

'Are you ready to do this?' Rex asked inside his head.

Upon hearing this question, Devo then answered, [No, I'm not. It's not going to be pretty]

'Come on old man, does living for thousands of years wiped your youthful ambition? I bet you haven't had anyone in the past that tries to break through this rapidly, so don't you think you should be more excited?' 

[If that's the way of you taunting me, you have a long way to go. Let's just get this over with]

Rex smiled inwardly before he puts both of his hands on either side of the lightning spirit core, he then exhale deeply and focus his mind fully on this process. In a moment, his energy started to envelop the lightning spirit core.

Naturally, the lightning spirit core resists his energy strongly, creating massive mana friction.

'System, activate the protection item that I bought if Calidora makes a move when I'm during the crucial part of merging with the lightning spirit core. I don't want her attacking me during my weakened state' 

'Also, activate the formation at the door if she tries to go out' Rex thought inside his head.

<Affimative, pinning Calidora's current location...>

<Success!>

<Preventive protocol has been activated!>

Upon seeing the notifications, Rex nodded lightly to himself.

As long as there's a possibility even if it's less than 1% that Calidora might take advantage of his vulnerable state, then he would take an absolute certainty that he needs to have preventive measures to stop her.

It's better to be safe than sorry, she might be being fake and play along for all he knows.

Rex then put his attention back to the lightning spirit core before he started pushing in his energy close to it, he would need to somehow wrap his energy around it before pulling it into his own spirit core.

'Okay, here goes nothing...'

BLITZ!!

"Argghh!" Rex grunted in pain, he was struck as soon as he pushes his energy close.

Naturally, unlike slowly cultivating the spirit core and becoming stronger through that like any other normal Awakened, absorbing spirit core provides a great risk if one doesn't know exactly what they are doing thanks to its absurd process.

Even as of this moment, Rex doesn't know anyone that has ever done this personally.

Rex is sure that somewhere, there's probably an Awakened that has done this. In the face of a huge reward that would propel their powers to a higher realm, there's definitely someone that's willing to take the risk.

But he has never heard of them. It's probably either they kept it a secret or they died.

It's especially riskier if an Awakened tries to absorb the spirit core of a stronger Awakened and that's because their mana would definitely be unable to overpower the mana coming from the spirit core they are trying to absorb.

Without being able to overwhelm it, then absorbing it would be practically suicide.

Just before he started his attempt to absorb Giana's lightning spirit core that's essentially at the highest realm achievable in this current era, he already bought the information from the System and gained a detailed explanation for the process.

Rex learned that the risk comes from an external object communicating with his spirit core.

Any spirit core is fragile no matter how strong the Awakened is, the slightest bit of error can cause the spirit core to fracture and break. It was due to the mana it excludes and the physical body that acts as a shield that an Awakened or Supernaturals can't destroy others' spirit cores from the outside easily.

Since the process involves letting an external object touch the spirit core, it's very risky.

Many would definitely die if they try doing what Rex is doing right now, but his physical body is that of a ninth-rank realm or even beyond, and the problems that others would experience in doing this would not affect him.

Of course, he still needs to be careful lest he makes a mistake.

Rex's body slowly turns into his Werewolf form as he tries to reduce the impact of Giana's lightning spirit core, he then tries again and this time, he's durable enough to resist the backlash of connecting his energy to the spirit core.

Now, the easiest part is finished.

After that is done, he carefully pulls the levitating spirit core toward his chest.

'Devo, circulate the spirit energy inside me faster. I'm going to start fusing this spirit core into my body' Rex instructed in his head, and Devo immediately does as he was told and started rapidly circulating spirit energy like a madman.

Just like that, he hisses through gritted teeth when the spirit core touches his skin.

Clenching his jaw strongly to resist the infiltrating pain that his internal body is experiencing, Rex started to guide a little bit of the spirit energy from Giana's spirit core and let it seep into his body.

It was excruciatingly painful, even though it's only a sliver of spirit energy that gets inside.

But Rex has never been someone that has difficulty dealing with pain, the years of him being trained mentally when he was still a human, and also the new page of pain that he experienced as a Werewolf makes his pain tolerance as high as it can get.

Easing through the pain, he keeps the process going without stopping.

During this process, his job was to control the energy from Giana's spirit core while Devo circulates the spirit energy inside of him and slowly merge it with the spirit energy that seeped into his body.

Like the System's explanation, this will be a perpetual motion.

Only when the spirit energy inside Giana's spirit core was depleted that the process will be finished. It can only be done until then, stopping mid-way will just result in a backlash as the merged spirit energy will be sucked out again by Giana's spirit core.

While this is happening, the energy coming from him started to become rampant.

But the room is built with very strong material, has a regenerative ability, and is also layered with protective barriers, so it would hold despite the rampaging energy being equivalent to an attack of a ninth-rank realm Awakened.

Calidora watches this, around her was a protective barrier that she cast earlier.

Not only does the protective barrier keep her out of the field of the rampaging energy, but it also protects Delta who is also beside her, watching Rex training, howling as if she was trying to root for Rex excitedly.

It was fine for a moment until a squirt of blood burst from Rex's chest.

As soon as that happen and his fresh blood landed on the ground in front of Calidora, her eyes completely changed and the black pattern returns alongside her eyes turning ruby again, signing that she was incited.

Earlier, she was not able to see Rex due to the thick mist, and she also didn't try.

But the moment her Eyes of Terror was activated, her eyes can instantly see the rapid pump of Rex's heart that course the blood throughout his body despite the thick mist coming from Devo's presence.

Calidora gulps at the sight of this, the bloodlust slowly came to her.

On the side, Delta sensed the change in the air around Calidora. She instinctively leaped back and growled at Calidora, baring her fangs menacingly. It seems Delta can sense when the Eyes of Terror was activated.

Just like that, Calidora squeezes her thighs with her hands strongly.

Anyone would realize that she was trying to fight back the bloodlust as she lowers her head and bits her lower lip, her thighs also started to bleed due to her claws stabbing through her skin cleanly.

Not only that, but her breaths started to become heavy and short.

Rex didn't realize this as his mind was fully fixed on the absorbing process, yet the System noticed the changes and activated a protective barrier around Rex's body, the preventive protocol was triggered in anticipation of Calidora doing something.

It went on for minutes, and the condition didn't get any better.

Calidora's blood energy started to seep out of her unwillingly, the bloodlust kept getting stronger and stronger, and the thirst for Rex's blood keeps on burning her throat before slowly spreading and burning her entire body.

Just like dehydration that keeps on amplifying with each second pass.

If anyone was to feel what she was experiencing right now, they would be shocked at how much restraint she have against such a powerful urge that wouldn't be quenched if she didn't taste Rex's blood right now.

But then suddenly, her eyes flickered and she exhales lightly, her breaths turned red.

While still keeping her head down to face the floor, a smile slowly appears on Calidora's face as the black patterns in her eyes slowly dissipated, and her eyes began to shift back to their original purple color.
