The Invincible Full-Moon System

Rex looks into the void in front of him without blinking his eyes, he heard what Adhara said and clearly disturbed by it. He's disturbed by it more because he can't rebut what she just said, everything she said is true.

But the thought of ending Ruston's life greatly stabbed his heart, he's not willing.

For the first time in their time together Adhara is convinced that she's thinking more clearly than Rex, the fact that he can't really do what he wanted to do has been clouded from his judgment.

Without knowing much about Ruston, Adhara is certain of one thing.

In order to find the supposed pack members alongside Ruston's family, Rex needs to dwell deep inside the Werewolf territory further than he has ever been. Having ninth-rank power make it plausible, but the declaration he did before worries her the most.

Just after he destroyed the Vampire Stronghold, Rex declared that he was victorious.

Other Supernaturals definitely heard of this mighty howl, and that includes other ninth-rank Supernaturals such as the Kings of the other races. With one wrong move and he might just be surrounded by them.

No matter how confident Adhara is with Rex's survival instinct, she doesn't want him to be reckless.

Being cornered by three of them will definitely spill his doom, so in order to really search for Ruston's family would rely most on timing. A perfect opportunity where other Kings are busy doing their things.

It's the only way he can ever do that, but Adhara doesn't know one thing.

Time is not on Rex's side and it keeps on pressing him like a heavy boulder on his back that grows heavier by the days, at the end the boulder will crush his entire body and takes his life with it.

Rex stood up slowly sparking a glance from Adhara who is still teary.

Wearing a pondering look on his face, Rex's eyes can't even look at Adhara as he made his way to the door before stopping just after he reaches the handle. Lifting his chin a bit, he then said without even turning back, "I'll try..."

After saying that, Rex left the room and closed the door behind him.

Even though it's still a vague answer but at least Rex is thinking about it, that much is enough for Adhara, "What are you doing, Evelyn... you're supposed to help him in times like this"

Just after leaving the room, Rex walks slowly along the hallway.

Despite trying to hide it his demeanor and pondering look shows that Adhara's voice still echoes in his ears, and every time it did his heart started thumping faster knowing that she's basically right. It's not going to do him any good in keeping Ruston alive.

Ruston is the source of his nightmare, but when given the opportunity to kill him. Rex hesitated.

Upon walking along the hallway intending to descend down to the first floor, Rex's eyes caught the sight of a figure standing in front of a door. It was Mrs. Greene, and she was looking directly at Rex.

"Mom...? How are you feeling?", Rex asks trying to hide his messy thoughts.

Looking over to the side, Mrs. Greene was a bit surprised to find Rex. But when their eyes locked onto each other, there's a weird feeling filling up the vibe around them which somehow makes Rex a little bit uneasy.

"I'm fine... you don't need to worry", Mrs. Greene replied.

A brief silence covered the both of them as both of them stood a couple of steps apart from each other, they seem wanting to say something to each other but the words got stuck inside their throats.

Rex was the first one to pull himself together and finally said, "Do you want to talk a bit?"

Hearing this, Mrs. Greene nodded her head.

Both of them descend down to the first floor before sitting on the sofa side by side, the others are doing their own thing so the guest room is empty. It was silence all over again, but instead of Rex this time Mrs. Greene is the first one to open the conversation.

"I remember the first time you asked me to let you join the military, and it's also the first time that we argued with each other. You were too young back then, but you were also very stubborn. Every day you keep pestering me about it"

Mrs. Greene said blooming a light smile remembering the old times.

Even Rex can't help but chuckle as he still remembers clearly how he kept pestering Mrs. Greene about wanting to join the military, "One day I decided enough is enough and asked why you really want to join the military, do you still remember what you said?"

"I want to kill all Supernaturals, that's what I said", Rex replied shortly.

Although he was very young back then, he answered quite firmly knowing exactly what he wanted.

Taking a deep breath, Rex exposes a small smirk remembering the old times, "But you keep saying no, asking me the same question for a month. I was very angry at you"

"I was making sure that you truly wanted that, and your answers narrowed down as expected"

"Hmm...?"

"As I keep asking you the question every single day, your answer started to change from killing all Supernaturals to killing bad Supernaturals, killing Werewolves, it keeps narrowing down. Until at the very end, I finally get the real reason out of you. All you wanted was to avenge your parents, to kill the Werewolf that killed your parents that night"

Upon hearing this, Rex's eyes widened for a brief second before his expression turns dark.

Since it happened years ago he didn't remember exactly how it went down, he didn't remember that his answers changed like that the more days he was asked the same question. It's surprising that Mrs. Greene can come up with something like that.

Mrs. Greene positioned her seat to face Rex, her eyes looking tenderly at Rex.

"For as long as I remembered, you've always had one goal. Kill that Werewolf..."

Pausing for a bit which somehow makes Rex subconsciously hold his breath, Mrs. Greene then continued, "I also remembered that during your years in the military, you've said to me that it's impossible to kill that Werewolf. It requires power that you never had"

"But now, you have that power. Where did you get that power from?", she added softly.

Rex was stunned in his place looking at Mrs. Greene's eyes without even blinking, he kept his mouth shut but that was because he doesn't know how to answer that question.

It was brief but Mrs. Greene's expression suddenly turns solemn.

Something that he has never seen Mrs. Greene wear in the years of them being mother and son, there's a hint of uncertainty in her eyes, "In order to gain that power, did you perhaps..."

Waiting for Mrs. Greene to finish, Rex's heart is thumping like a war drum.

Unbending tension started to fill the entire room as Rex waited for Mrs. Greene to finish her sentence, it was the longest couple of seconds in his entire life. But instead of continuing, Mrs. Greene suddenly shakes her head and stood up.

From the looks of it, she seems to decide not to continue her sentence.

Rex looks at her with wide eyes, she stood there for a moment before she finally looks down at him, "I'm proud of you...", a simple sentence slips out of Mrs. Greene's mouth before she walks away.

Even after Mrs. Greene went back into her room, he was still stunned.

It took a bit longer for Rex to snap out of his daze, he then turns his head up to the second floor.

'She heard it didn't she...'

A moment later,

Ever since the little talk with Mrs. Greene, Rex has met up with Gistella and gives her Ian's corpse so that she can absorb it and gets stronger. It was the corpse of an eighth rank Supernatural, so she needed time to absorb it.

But without a doubt, she will definitely break through to the next realm, or at least got closer to it.

Since Adhara has already gone out of the training place, it's clear to her that the possibility of Seth saying something is very unlikely. In fact, she thought that it was impossible to make Seth talk.

It was precisely because of that, she finally suggested killing Seth.

Nothing good will come out of torturing him, even Kyran's method didn't work on him.

Although he told Seth that he will be using Decimation Fervor on him, it was nothing more than a bluff to make him talk. Without the corpses of the things that he had already killed, Rex can't use Decimation Fervor on him.

Killing Seth is tempting but Rex didn't want to rush it and just sat in the throne room thinking.

Just like waking up with a spirited soul, the talk with Mrs. Greene somehow gives him immense strength that wipes all of the strain he was having in his mind from the pressure coming at him from all directions.

Because of that, he now has a clearer mind which prompted good ideas to him.

Another day passed,

Rex has decided to meditate through the night to think about his next move and also train his Lunar Light element, he has rearranged his thoughts for the next move he was going to take.

Other than that, he also used the Skill Upgrade Ticket that he got for one of his skills.

Claw of Tormentor now has been upgraded into its higher form, Executor Slash which has an even more devastating enhancement that is not only able to inflict corrosive properties onto the target but also phases through armors.

It was a very strong attack skill that he will definitely be using more in future fights.

Expecting an unavoidable fight with the ninth-rank Supernaturals, Rex also decided to gear up with the gold in his pocket as much as possible. Unlike before, he's now in the big leagues and every little power will determine the final result of a fight.

Because of that, he has learned a couple of things from the system.

Since buying ninth-rank or even eighth-rank weapons is very expensive even with the gold he currently has, Rex decided to went through a cheaper way that is by learning to engrave runes himself.

From the system shop, he bought Rune Master I and Rune Master II.

Just like that he learned how to engrave runes onto battle equipment and weapons, and using that knowledge he decided to make the Amuerus Katana stronger. It has a very nice innate ability.

Each slash reduced 1% of the target's stats.

In the early realms, 1% doesn't seem like much. But in the ninth-rank realm, 1% is very high.

Take Rex, for example.

With the activation of King Mark, his strength stat points reach more than 200,000 points. 1% from that would be 2,000 points, that alone shows that one slash is detrimental to a fight against a ninth-rank entity.

Based on the system, the current Amuerus Katana is useless against ninth-rank Supernaturals.

Not only do they have superior energy surpassing all of the other Supernaturals, but their bodies and even souls are way stronger to the point that most weapons in existence can't harm them without the use of ninth-rank Awakened energies.

Rex has asked for information, and now he needed to create his own ninth-rank weapon.

With the knowledge of a Rune Master inside his head, he bought six additional runes to be engraved on the Amuerus Katana and raised its rank to the ninth rank. It costs him 2,000,000 gold which is almost 80% of his gold.

Pretty hurtful when he thought about it, but this will definitely help him win fights.

Ability Enhancement Rune and Greater Ability Enhancement Rune are used to strengthen the innate ability of the Amuerus Katana. Unbreakable Durability Rune and Anti-Greater Energy are used to raise the durability to make it very hard to break. While Anti-Life Rune and Myriad Sharpness are used to increase the attacking power.

Despite being the first time doing this, Rex has help from the system.

On top of the four runes engraved on the Amuerus Katana, six additional ones are engraved on it which stretches almost reaching the tip. With the last rune engraved, the Amuerus Katana emits intense energy that would shake the entire mansion and afar.

But since it's the throne room, the energy didn't spread out thanks to the runes on the walls.

Rex looks at the final product in marvel as the Amuerus Katana becomes even more enchanting than before, its energy has become even more vibrant and the wolf head cross-guard has its eyes glowing with red energy.

Not only that, when he swings the katana two after images were created.

It's the ability from the Myriad Sharpness that creates this after images, Rex tries to swing it lightly at the ground and he becomes even more excited seeing the effect from one slash.

Just like using any other weapons, a cut was created on the ground.

But that was not all as the after images that follow after hit the same place two more times, a slash from the Amuerus Katana now equals to three slashes at the exact same time. Something that Rex has never seen before.

"Forget the Origin's Weapon like the Blood Devourer"

"At this rate, I can even make weapons equivalent to Origin's Weapons. With this, I'm confident that I can slay ninth-rank Supernaturals...", he mutters with an excited smirk.

A moment later,

Rex got out of the throne room upon sensing someone arriving at the mansion.

'It should be her', he thought heading towards the front entrance, and true enough the front entrance was opened revealing Tandu that was surprised to see Rex already standing there.

Recovering from his surprise, Tandu then said, "Sir, someone wants to meet with you"
