The Invincible Full-Moon System

Crash!

An invisible shockwave of pressure exploded and expanded far from the point of explosion. It comes from an uncountable distance away inside the human territory, far from the Great Barricade where the fight happened.

But through that distance, the invisible shockwave manages to reach them.

Even the shattering sound of glass also followed after the invisible shockwave, displaying clearly that something is indeed broken due to the clash between Rex and the two ninth-rank realm Awakened that baited him to use his power.

It was not destructive, but there was a feeling of imminent ruination creeping into their hearts.

Almost as if there's something that forces their hearts to tremble, a horrifying otherworldly creature that the world has never seen before. The kind of creature that makes the likes of King Solomon turns tail and flees away.

Rumble!

Rex and the others looks in the far distance and saw the sky being split open.

Many tears in the dimension that was caused by Rex decorated the sky and turned it into a sight of a nightmare. But at the far horizon, there's a black dot covering devastating distance within a second that split the sky into two.

Something inexplicable, something which has evil that reaches the souls of every Supernatural.

"What is that mark on your back? And who is this Executor?" Adhara asked in concern.

Adhara was not the one feeling the burning mark on Flunra's back but she can feel the burning sensation keeps climbing higher, Flunra's furs and skin started to sizzle and the shape of the mark was imprinted into his muscle tissues.

It looks generally horrifying and painful, a feeling that she can't imagine.

Gritting his teeth while looking at the far horizon, Flunra then replied still enduring the burning sensation that is gnawing at his pain receptors and nerves, "We Supernaturals are slaves to the ancient humans back in the ancient era, the war prisoners which are Supernaturals that killed more than three ancient humans were not shown mercy and was branded with a slave mark, a mark that will persist to the end of our lives as a slave to the ancient humans"

"It acts as an identifier of a slave, and also a patronizing punishment when necessary" he frowned.

Even though Flunra hasn't felt the slave mark for so long as he has always been dormant and focused on surviving, this feeling is something that instantly brings back the trauma of the past. A trauma that any Supernatural with a slave mark has.

Something many want to forget but can't and persist to occupy the corner of their minds.

"Only a handful of individuals can summon the slave mark and inflict the slaves with immense pain and also cancel their abilities, the Executor is one of those individuals. A being of absolute evil, the one who is tasked by the First Human Emperor to punish those who are deemed must be punished" Flunra continues with his eyes trembling at the sight of the incoming black dot.

Rex heard this and can't help but sucked in a cold breath, he's now faced with a new enemy.

Although he's not fully a Supernatural despite having a Werewolf bloodline, he's considered a Supernatural by the humans and this Executor would definitely think so too. It's not a guess, the Executor would definitely attack them.

"Adhara! Get out of here first and bring Flunra with you!" Rex glanced sharply and shouted.

Even though Adhara feels like she can help with the help of the Herald Mark, the enemy that was about to arrive is definitely something that can't be handled even if she worked together with Rex to try and take it down.

Knowing that she quickly nodded her head before she grabbed Flunra.

With a wave of her hand, she intends to activate the formation that would teleport them back to the castle. Rex has prepared everything so that their safety is secured, the formations engraved inside the forest are there to teleport them back.

After Adhara and Flunra get away safely, Rex would also teleports back to safety.

But as the formations inside the forest glowed brightly, Adhara suddenly felt the link between her and the formation break out of nowhere. It catches her off guard, and she snapped her head back to Rex, "I can't! I think something is wrong with the formation!"

"What?!" Rex widened his eyes in surprise, he was not expecting this to happen.

Frowning for a second, he then decided to ask the system about this, 'System, what happened to the formations? I bought them for a huge deal of money, how come it didn't work?' he asked in a hurry.

<The formations are unable to work due to the Latch of Chains inhibiting the dimension>

'Latch of Chains? What is that?' Rex asked in confusion, that is a foreign term for him.

<Latch of Chains is a presence-related skill that locked the space around the caster which renders teleportation-related skill, formation, or items from able to be used. They can be activated only if the caster allowed or give them permission to be activated>

Upon reading this, Rex clenched his jaw knowing that this skill should come from the Executor.

Looking at the black dot that is already closing in even though it was very far before, Rex frowns as this is outside the realm of his expectation, 'The Executor is still very far but its skill reaches here? Moreover, it's so fast that we can't possibly outrun it if it's locked onto us'

"I'll buy some time for you to go back, leave right now!" Rex shouted without any other choice.

No matter how much they try to run the Executor would definitely catch up. Aside from that, Flunra also seems to be stripped from his power and ability due to the slave mark so he can't really use the ancient runes to hasten their speed.

It leaves no other choice than Rex leaving behind to buy them time.

'Will the Executor be able to follow them? Or even search for them?' Rex asked the system quickly.

<Yes, Mist of the Starfallen item is recommended to mask Adhara and Flunra's presence so the Executor is not able to sense their presence. Does the user want to buy 2 Mist of the Starfallen for 200,000 Gold?>

'Buy three of it!' Rex quickly answered before he turns to face Adhara.

Pulling out two Mist of the Starfallen from the inventory that took the shape of a dark greyish orb that emits subtle energy, he threw them to Adhara, "Use it quickly and leave, don't waste a single second, or the Executor will catch up to you"

Adhara catches the two dark greyish orbs with her eyes still locked onto Rex.

Inside her eyes there's a sign of reluctance, she doesn't want to leave Rex here to fend off the Executor alone. Especially, when Flunra said that this Executor is a purely evil entity and also sounds very strong.

Rex smiled reassuringly to convince Adhara, "I'll be okay, just go!"

Knowing that there's no time to waste, Adhara takes one last look before she flees with Flunra.

Turning his head back to the black dot at the far horizon, he then telepathically said to Adhara, 'I'll buy some time for you to go back, run for the castle, and don't look back no matter what happened. Even if I die here, don't stop running...'

Upon hearing this ringing inside her mind, Adhara feels her body want to turn back and help.

Out of everything she doesn't want Rex to die, she doesn't want that to happen, she wouldn't be able to live with herself with the fact that Rex is dead. But even then, her legs keep moving away due to Rex's voice ringing inside of her.

Adhara clenched both of her fists in absolute frustration, she knows that she can't head back.

If she heads back then if Rex really did die then he would've died for nothing, a meaningless death is an ultimate disrespect that she can give to Rex. Without having no other choice, Adhara keeps on escaping with tears filling her eyes.

'Don't die, Rex! Come back, I don't want you to die!' Adhara screamed inside her head.

Just as Adhara's wailing voice echoed inside his mind, Orson stood up with a nasty smirk on his face, "We've got you now, Royal Black Prince. Do you really think we're that reckless to fight you who is obviously stronger? You underestimated us too much"

Upon hearing this, Rex slowly glared at Orson with immense killing intent, "Shut up."

Swoosh!

Splash!

With nothing but a wave of his claws, Orson isn't able to react before his shoulder exploded and his right arm got severed from his torso. Rex used the Executor Slash skill and managed to do that with ease, he was not playing around anymore.

Rex came here for Kyran, but they used Kyran to lure him here and awaken the Executor.

Out of everything that he should be feeling right now, immense fury is bubbling inside his body, reaching the boiling point of his anger. It was not the fact that he got baited here, but it was the fact that they used Kyran to cause this.

Something like this is enough to anger him, his bloodstream intensified due to that.

"Grrghh! Struggle all you want, the Executor is coming! And by the end of this day, the name Rex Silverstar would only be nothing but a nightmare of the past" Orson mocked while holding his severed right arm, unyielding even with the fact that Rex can end him right now.

But at this current moment, Rex's eyes met with Brigitta's eyes.

Although she should be rejoicing with the current turn of events, she turns her head away unwilling to make eye contact. 'Out of the ninth-rank realm Awakened of the humans, only two don't take part in my parent's death. Brigitta is one of them. I thought she was not like the others, but it seems she's as rotten as the others'

'Using those close to me to get this outcome, she's a scum in sheep's clothing' Rex thought.

Even though they were practically enemies now, he has never thought of using people dear to his enemies to reach his goal. At least not the first one insinuating that kind of dirty play, but Brigitta did it so casually.

Rex even respected her due to her actions, but that respect is now gone completely.

While still looking at Brigitta despite her not being willing to look at his glowing red eyes, he opens his mouth and whispers with a calm tone, "I will remember this, and will not forget anything." a set of haunting words seeped into Brigitta's ears.

It was as calm as the sea, but hide a meaning that is harsher than a violent whirlpool.

Brigitta knows that the sentence Rex said earlier was a threat, and he would definitely pay this back.

'Not my intention, but you came here...' Brigitta thought while biting her lower lip.

Ignoring Orson's rant and Brigitta's hateable presence, he decided to focus on what was about to come, 'System, is there anything that I can do to increase the odds of fighting against the Executor? I still have two chances to buy anything in the shop, tell me anything that can help me for the upcoming fight' he asked hurriedly.

<Calculating options...>

<Calculation finished, there's nothing that can help the user instantly in the fight about to come>

Upon reading this Rex can't help but frown, it seems if he wants to fight the Executor then he would need to survive and train the available options. In terms of skill or items, there's nothing that can help him in this upcoming fight.

Swoosh!

Kaboom!

Before Rex can do anything, a sonic boom sound cracked the sky alongside a powerful shockwave.

Rex looks up and saw a figure shrouded in absolute darkness already standing in the sky. Bringing alongside the figure was the sky turning greyish, the sky that is supposed to be bright blue turned into a bleak color.

Now his eyes bear witness to the first ancient human he sees in person, the Exutor has arrived.
