The Invincible Full-Moon System

Rex stood near the teleportation formation with a book in hand.

He was waiting for Naela to come back while reading the Basic Book of Combination—he got from the System. As he was reading the book, his mind wandered elsewhere as he called out Devo from within.

In a crackle of black lightning, Devo manifested beside Rex with his arms crossed.

"Nothing was happening, I'm surprised you called me out," He mused in ridicule.

Despite having a spirit and awakened relationship, Rex never calls him out if it is not for a fight or other things. A spirit might be assimilated by an Awakened, in order to go past an Awakened's limit, but they are also living beings.

Sometimes, spirits need a break from all the fighting and pursuit of strength.

"How old are you again?" Rex asked nonchalantly, his eyes still glued on the book. "Aren't you too old to be sulking like this, Devo? If you wanted something, then you should have said it to me directly"

Upon hearing this, Devo scoffed as it was no use arguing with Rex about this.

Even then, Rex decided to also summon Amanir out.

"Go and play, the adults are going to have a talk," Rex mused, letting Amanir do whatever.

Amanir's forced out a fuming smile when he heard this, he was annoyed that Rex was saying it like that when he was way older than Rex and even his lineage. Regardless, Amanir did not retort and flew away, cursing Rex in his mind.

"Say it, what do you want to know?" Devo impatiently asked.

Rex flipped a page in the book before he replied, "I'm planning to increase your aptitude"

Despite his earlier complaint, Devo's eyes widened when he heard this.

It was so shocking that he did not realize his jaw was already hanging on the floor—guessing Rex's next move was an impossibility, he always came with something insane, "Are you in the mood to listen to me now?" He asked again.

Devo cleared his throat, recovering from the shock—he was clearly tempted by this.

"As you might know, I have other elements that are stuck at the peak of the fifth-rank realm, but assimilating with more spirits is a hassle for me. I couldn't even begin to imagine, having four more spirits like Amanir, so that's why I'm going to increase yours and Amanir's aptitude to sustain more elements," Rex continued, explaining his strategy to Devo.

Upon hearing this, Devo nodded in understanding, "But how are you going to do that?"

"Are you going to use your weird power to summon a miraculous item again?" He questioned.

Rex shook his head, Devo was referring to the System.

But the System itself had already advised him the way to increase their aptitude.

"No, I'm going to pit both of you against other spirits and have you devour them" Rex replied.

At the realization of what Rex was trying to do, Devo's eyebrows dipped into a frown, he was not expecting Rex to know about that, "In order to do that—the challenged spirit needs to be as strong as me and Amanir and a Spirit Adjudicator must be present to witness the fight. Do you even know who will be the Spirit Adjudicator?"

"Yes," Rex nodded, the System already told him. "I'm going to meet with the Spirit Emperor"

"What?!" Devo gasped in shock when he heard that. "Are you insane? He's going to kill you"

Knowing that Devo would react like this—Rex glanced over to him, with a serious gaze, "Ah... so that's what I should be expecting. Is it wrong to ask him to act, as a Spirit Adjudicator? I'm going to have him do it, no matter what"

"It's like a peasant asking you to be present at a small event, it's disrespectful!" Devo replied.

Out of everything he could think of, Devo was not expecting this at all.

Rex might be strong, but the Spirit Emperor is an absolute overlord of the entire Spirit Realm.

Going to his realm and disrespecting him would not be a good idea.

"Just think about this again, you would be crushed if you really do that. Even if somehow, the Spirit Emperor did accept to become a Spirit Adjudicator, I don't know if I would triumph over the fight, not to mention Amanir..." Devo muttered, shaking his head—this was a bad idea.

Listening to this, Rex put on a cheeky smile, "Is that fear I hear in your voice?"

"Fear? It's rationality, you moron!" Devo barked back in anger.

But him being angry showed that he was indeed fearful as he could lose and be devoured.

Not even minding this, Rex leaned back against a tree with both hands behind his head, "I'm quite prideful when it comes to strength. Do not forget who you are, Devo. You are my spirit, which means you represent me, and I would be damned if I let myself lose face"

"What are you planning to do?" Devo asked, squinting his eyes.

From the sound of it, Rex was not going to play fair, and that was quite obvious.

As opposed to answering, Rex only replied with a mysterious smile.

He decided to talk about this to Devo, in order to know what kind of a person—the so-called Spirit Emperor was—and now he gained what he wanted. I don't know much about the Spirit Realm, but I reckoned it wouldn't be exactly the same as this realm. From Devo's reaction—I could assume the Spirit Emperor is prideful, and who wouldn't? But that is exactly what I am going to use against him.

Knowing the personality of the person he is going to meet is always a good habit.

It would make the process of the encounter easier.

Just then, however, Rex and Devo turned to the side when two figures came approaching.

Upon seeing the figures, Devo excused himself and went back into Rex.

"Evelyn?" Rex uttered in confusion, he was only expecting Naela. "Why did you come here?"

As opposed to only Naela coming back with him, Evelyn surprisingly also came with her.

Stuttering for a moment—she then eventually replied, "I'm coming with you,"

"Am I not allowed to come? I missed going to places with you" She added pleadingly.

Rex was surprised, he had tried to make up with Evelyn earlier but he didn't expect her to act like this instantly. But then again, he was going to hunt for Angels, Evelyn shouldn't come lest the city might need her.

Since the others were busy preparing for the upcoming challenge, there was no one present.

No one is in power to make the decision if something happens.

Realizing what Rex was thinking right now, Evelyn stepped closer and continued, "Am I really not allowed to come? I thought you're confident against the Angels—but it can't be helped if you're too incompetent to not be able to protect me while hunting them"

Upon hearing this, a vein bulged on Rex's forehead as that was definitely a taunt.

Even though he knew it was a taunt, he couldn't help but be annoyed by it.

"Who said I couldn't? I was about to say yes anyway" Rex replied, exhaling a rough breath.

Seeing this, Evelyn smirked as the three teleported away.

It was the next day.

Having no other choice, Rex brought along Evelyn in his Angel Hunt.

Other than Catherine, Mavenna also came with them as Rex didn't trust her enough to be left alone in the city, without supervision. Since the others, were busy—there was nobody else to watch over her.

Rex had already taken some preventive measures, but it was not foolproof.

Due to that, Mavenna also came with them.

"I don't want to come, I want to lie all day and do nothing but sleep!" Mavenna cried aloud.

Since the terrain had changed completely after the Second Breath washed over the world, all four of them had been walking at a fixed rate after managing to exit the Chrono Hollow. None of them knew where to go, the place was uncharted for them.

Moreover, Rex was completely blind to the place as the scouts weren't able to reach here.

None of them were able to reach the other side of the Chrono Hollow.

He needs to wait for them to train in the force user academy before any crucial progression.

"I've been meaning to ask this..." Evelyn suddenly voiced out her mind, looking down to the wet ground, with a grim expression. "Since when do you have a Succubus—as a pet?! How come I don't know about this?!"

Upon hearing this, Rex smiled wryly, "It's not like that, I found her making trouble in the city"

"Nice to meet you, I'm Mavenna" Mavenna introduced politely.

Sensing that she was about to say something unnecessary, Rex glared at her and raised the leash in his hand, signaling that he would unbind Mavenna's collar, if she acted up. Mavenna trembled at this sight, the suffering she felt from having the collar removed, was still fresh in her mind.

Evelyn looked at Rex and squinted her eyes, "Did you touch her?"

"Huh? Where did that even come from?" Rex was taken aback, speechless at the question.

Despite Rex being confused, as to where that question came from—it was natural for Evelyn as Mavenna was wearing, extremely revealing clothes. Her womanly goods are practically in view to anyone.

Pivoting away from Rex, Evelyn stared at Mavenna, "Did he touch you?"

"No, Master Rex hasn't touched me yet. I'm still a virgin," Mavenna replied innocently.

But this answer turned Evelyn's face crimson, fuming in anger.

"Since when did you ever call me that? And what do you mean by 'yet'?!" Rex commented.

Mavenna never called him 'master', that never happened.

Additionally, she was obviously playing around as he was not planning on doing anything.

Upon hearing this—Mavenna tilted her head in confusion, "I thought the tattoo you placed on me was meant to bind us both as master and slave? Is that not the case? Hmm, odd—I swear I remember you want me as your slave"

Listening to this, Rex was cursing Mavenna in his head.

He could feel Evelyn's fiery gaze burning through his skin after Mavenna said that.

It was more annoying when Rex saw a glimpse of Mavenna's smirk as Evelyn turned away.

"Rex—I know I told you to have anyone other than Calidora, but that was before Calidora was in the fray..." Evelyn uttered—her voice was anything other than sweet. Additionally, the fiery aura began to ablaze as the group took an abrupt pause. "And now you already set your eyes on another one, a Succubus no less?"

Seeing this, Rex shook his head and sighed, "Fine, let's get this over with..."

BAM!

Moments later.

A vivid—hand-shaped red mark could be seen, on Rex's cheek, the outline of slender fingers clearly imprinted on his skin. He had gotten a vicious slap from Evelyn, even though he didn't do anything wrong.

But since the two had only made up, he decided to suffer through the slap.

Of course, that doesn't mean he was going to let this side for Mavenna.

Glancing over, he stares daggers at Mavenna who puts out her tongue in response.

If Evelyn wasn't here, I would already activate your damn tattoo.

Cruising through the wet grassland with the help of demonic horses that Mavenna was able to summon, the group of four eventually reached a half-submerged massive statue of some sort of a knight.

Upon seeing this, Rex then looked over to Catherine who had her senses entirely blocked.

Other than the demonic horses, Mavenna could also do this.

Signaling for Mavenna to take down her spell, the pinkish influence in Catherine's eyes began to dissipate until it disappeared completely. Only then that Rex ask, "You said that you have a way to contact the others, how would you do that?"

"I- I need to be high in high grounds to do that..." Catherine replied meekly.

Rex squinted his eyes, remaining silent for a few seconds.

Feeling uncomfortable and nervous, Catherine added, "I swear, I'm not lying!"

Seeing that she didn't seem to be lying, Rex nodded and turned to a rock formation ahead.

"Okay, let's go there," Rex pointed at the rock formation before the group moved again—but as he was heading towards that rock formation, his eyes, scanned the surrounding place. "It seems Calidora is doing great. She might be pregnant—but the power of her eyes, are really something..."

On the other hand, Evelyn looked at him from behind, her gaze was troubled.

'I came here because I'm worried, but what could I do even if I'm here with him...?'
