The Invincible Full-Moon System

Brak!

Like a frenzied couple that heard their partner screaming at the top of her lungs, Evelyn and Naela barge into Gistella's bed chamber with clear concern on their faces. It was not a regular scream, the scream was filled with fear and agony.

Gistella has never screamed like that, it's why Evelyn and Naela were so concerned.

Stepping hurriedly inside the bed chamber they saw Gistella crawling back on the floor while looking at the glazed windows that show the night sky, there is fear inside her eyes when she turns to look at Evelyn and Naela.

A sense of hope can be seen in her eyes when she saw Evelyn and Naela inside her room.

"I- I saw something! I saw it standing outside!! It's trying to kill me!" Gistella screamed while pointing at the glazed window. Knowing that there was a rogue cursed creature on the loose, Evelyn instantly went to the window and look outside.

Even though she scans around to try the thing that Gistella finds, there was nothing.

Only the sight of the dancing trees that are being swayed by the winds, alongside the cold scenery of the night can be seen. Not one glimpse of anything out of the ordinary, and this makes Evelyn frowns, "I don't see anything..."

"I swear! I saw that thing standing outside and tell me that it wanted to kill me!" Gistella rebutted.

Naela is already embracing Gistella on the ground and can feel her entire body shaking, the fact that Evelyn didn't see the thing that Gistella saw doesn't mean that she was lying. From the looks of it, Gistella is definitely telling the truth.

Looking at Evelyn, Naela then mutters, "I don't think she's lying"

"I'm not saying that she's lying either. Naela can you stay here with her? Keep accompanying her, and don't look outside since that cursed creature might come back again" Evelyn said, she was going to tell Adhara about this.

But they would definitely not go out of the castle, that is what Rex told them to do.

Upon hearing this Naela nodded her head, agreeing to stay with Gistella. Out of the others, she feels comfortable with Gistella the most, and also she's glad that she can help out in this castle that hosts terrifyingly strong individuals.

As she was about to leave, Evelyn realizes that Gistella's face is very pale.

Gistella usually has a marbling complexion that makes her charming, but right now her complexion looks sickly. Under her eyes were also panda bags, it's unnatural for a Werewolf to have this kind of thing since they don't require any sleep.

With that Evelyn rushes outside intending to talk to Adhara about this.

'As much as I want to trust Gistella, why would the cursed creature want to kill her? I thought that the cursed creature is after Rex for some reason' Evelyn thought while walking through the hallway, she was confused about this situation.

Rex told her that the cursed creature wants to kill him, but now Gistella said that it wants to kill her.

It's unclear which one is true, but the fact that there's a threat out there that disturbs the peace of the castle is a problem. Despite wanting to do something, it's best to wait for Rex to come back and deal with this situation.

'Also, why did she looks sickly?' she also thought in confusion.

No matter how much she trusts that Werewolves are immune to most sicknesses especially Werewolves with high-ranking bloodlines like them, Evelyn believed that something is making Gistella sick like this.

Just as she thought of that, she stopped when she sensed two figures outside of the castle.

"Rex! Flunra!" Evelyn exclaimed excitedly.

Meanwhile, outside of the castle, Rex and Flunra arrived back from the fight against the Tigerman Race. It was their victory, and Flunra even proved himself worthy of Rex's trust and the power is given to him.

Overall, it was a good haul. For the time being, the secret rebellion group's secrecy is guaranteed.

"I won't judge your decision, but the Dwarves and Dark Elves might not like it when you spared King Samobas. Many of their kind died in that battle, they would seek an answer regarding your action" Flunra suddenly said while walking back to the gate of the castle.

Upon hearing this Rex chuckled, he knows what the aftermath of his decision will be.

But there's no hint of trouble in his expression, he seems very relaxed and has an air of mysteriousness around his body, "Let them try and search for an answer, I'll give it to them" stopping on his track, Rex then glanced at Flunra, "Besides, who said that I'm sparing King Samobas?"

"Hmmm?" Flunra frowned when he heard this.

From his point of view, Rex spared King Samobas and even lets him get back to his kingdom without further damage or war. It's quite obvious to him that Rex is sparing King Samobas from death.

Although he's still confused, Rex doesn't intend to explain himself and resume his walk.

"Wait, Rex... just what makes you choose that path instead of exterminating the entire Tigerman Race? It's easier to do that with your power, and there's no risk associated with that path too" Flunra called out to him from the back and asked.

Upon hearing this, Rex stopped in his tracks, lowering his gaze to the ground.

A scene is already replaying inside his mind, the scene that happened when he got near the fight.

~

Swish!

Slash!

As he got closer to the battle between Flunra and King Samobas, he came across the escape route of the Tigerman race, running from the battle and into evacuation. Countless of them are sneaking through the woods unnoticed.

But it's a shame that they came across Rex, and he massacred them without thinking much.

Screams of absolute agony as Rex's claws draw a beautiful arc that is enthralling to see, the arc ripped apart any Tigerman that was caught in its trajectory, sparing none as these Tigermen are only below the fifth-rank realm.

Nothing is stopping him, and in a short amount of time, all of the Tigerman died.

"If we're exterminating them then there's no need for survivors, this should deal with a great deal of them" Rex thought while looking around the panorama filled with blood, guts, and death. It was something that his eyes were already accustomed to.

When he was about to leave, his sense picked up something hiding behind a tree.

Rex vanished from his spot and reaches the tree, he appeared right in front of three Tigermen. One is an adult while the other two are young ones, the adult and the young one are female while the other young one is a male.

It's easily seen from their muscle proportions and the length of their tails.

Upon seeing Rex appearing like a ghost, they were shocked and scared except for the young female Tigerman that is busy looking and picking flowers on the ground. "Please don't hurt them, spared them, and take my life instead!" the mother Tigerman pleaded.

"I'm not going to let you hurt my mother!!" the young male Tigerman shouted and stand in front.

Inside the eyes of the young male Tigerman was a blazing fire, a young but strong resoluteness of wanting to protect his mother, even though he probably saw how Rex killed the Tigermen that was running alongside them easily.

But even then, Rex doesn't have a glimpse of mercy. Only a cold look on his face.

Slowly he raises his claws intending to end these Tigermen, none of them should be alive or the alliance would suffer the consequences. As he was about to strike down, the young female Tigerman pluck the flowers and chuckled happily.

Her mind is still too young to understand the dire situation that they are in right now.

With the flowers in her hand, the female young Tigerman glanced to the side and finds Rex standing towering over her. Instead of fear, she smiled and walks over to him and grab the edge of his clothes, "Mister, I think these flowers suit your color" she said with a light dulcet voice.

Looking at the flowers, they were vibrant white which stands out against Rex's black clothes.

"Sister! Don't get near him!" the male young Tigerman pulled his sister back, and the flowers fall from her hands slowly before hitting the ground, right above a pool of blood from the other Tigerman's corpse.

As if that pure flower hitting the pool of blood is a sign, Rex lowers his claws.

'I've already killed the ones responsible for my hatred, I've avenged my late parents. Killing them right now will just make me exactly like the killers of my life's tragedy...' Rex thought, he clenched his fists and turns his body around.

Knowing that he was in the wrong, Rex decided to leave and left the three Tigermen alone.

~

Rex pauses for a moment while looking at the ground, many things are mixing in his mind.

"Because I don't want to be like them..." he mutters silently.

Flunra was confused about this answer, he can't exactly decipher what Rex means by that.

But then the both of them saw Evelyn standing at the top of the wall, waving at them. There was also a clear frown on her face that screamed trouble. With a light dash, the two of them instantly landed on the wall beside Evelyn.

"What's wrong, Evelyn?" Rex asked, he can see that something happened.

Grabbing ahold of Rex's hands, Evelyn then replied with a hint of hesitation, "It's Gistella, she claimed to see the rogue cursed creature and said that it wants to kill her. But I think she's sick, she doesn't want to say it but I'm quite sure about it"

A moment later, Rex arrived at Gistella's bed chamber.

Upon arriving he saw Naela and Gistella lying on the bed, but his eyes were focused on Gistella that is sleeping and looked odd due to her sickly complexion. 'It's the curse inside of her, the link is developing just like the system said' Rex thought with a soft expression.

It's the first time he saw Gistella in this state, and he's not taking it decently.

Striding towards Gistella's side of the bed he sat down on the edge of the bed before he grabs her arm to scan her with the system, and also to tell her that he was by her side. "Dark Elves are experts in terms of curses, right?" Rex suddenly asked.

"Y-Yes, but our powers are limited" Naela replied softly.

Rex nodded his head before he glanced at her and asked, "Gistella is infected by a curse, I think it happened when the castle is attacked by a horde of curse creatures when I'm not here" he explains and pauses, sighing lightly he then continues, "Is there anyone in your kingdom that can identify a curse? Or at least someone that can find out more about the curse inside of her?"

"I think there's someone, her name is Qonvale. She's the only Cleric in the kingdom" Naela replied.

Upon hearing this Rex thanked Naela and nodded his head, he can't only rely on the system and would seek others' opinions. In terms of curse knowledge, he only knows that there are two types of curses and that's basically it.

Out of everything, he's no expert. It's good if there's someone that can look at Gistella's condition.

<The link between Gistella and the curse is still juvenile, her condition will keep on deteriorating as the link develops. Until the link matured, the curse inside of Gistella wouldn't be able to be exactly identified>

'She's going to deteriorate even more...? Just how bad will she be when the link matured'

Not wanting to see Gistella in a worse state than this, Rex then decided to ask the system to seek alternatives. 'What is the cost to learn everything about curses?' he asked, but the answer makes his shoulders slump down.

[10,000,000 Gold is required to learn Curses]

It's way out of Rex's buying range, he only has less than a million which is only 10% of the cost.

Rex then stands up from the bed before he heads to the door without saying anything, he stopped by the door before glancing at Naela, "Keep her accompany for me, she's important to me..." he said before he opens the door and leaves.

Upon hearing the gentle tone, Naela was surprised as she was not expecting this.

Naela's perspective of Rex was the fact that he has immense power and has little to no emotions aside from reaching a higher power, creatures that are at the upper echelon of power tend to be like that.

Even her father, but Rex's gentle tone has nothing of that sort.

Although it was brief, Naela can hear the pain and broken part of Rex that spoke those words. A tone that only those who have deep trauma can generate those words, and that gives a new light of impression for Naela.

"Don't worry, I won't let her feel alone..." Naela mutters with a light smile.

Going through the hallway quickly, Rex reaches the great hall.

Sitting at the stairs of the throne was Adhara that seems to be working on her elemental prowess, he can sense that Adhara's Spirit Core is about to reach completion. In fact, it was on the verge of being complete, and pushing Adhara into the seventh-rank realm power.

Rex waited for a moment as the violet fire started to vibrate around Adhara's body.

Soon enough the violet flames started to become even stronger and emits a horrendous amount of heat, the great hall slowly turned a purplish hue as a monstrous fire serpent appeared on Adhara's back majestically.

If not for the powerful castle, her aura would've shot to the sky.

Fire mana started to create a vortex around Adhara as her spirit core is reaching its fullest potential.

It needed only a minute before out of nowhere, a loud explosion resounded, shooting violet flames to the surroundings. After that explosion, Adhara slowly opens her fiery violet eyes before she controlled the new aura leaking out of her body.

Roar!

The fire serpent beside her roared in response before it went back to Adhara's body.

With a simple thought, the leaking violet fire got sucked back into her newly enhanced body.

Adhara looks down at her hands and finds a new sense of power coursing inside her veins, it feels rejuvenation and is the sensation that she missed. "Seventh-rank realm? Not a problem for you, if I may say" Rex commented from the side.

Upon hearing this, Adhara glanced to the side with a wide smile on her face.

"Rex? You're back already?" Adhara asked as she stands up, the vibrant violet flame elemental mana can be seen warmly surrounding her body. Due to her just reaching the seventh-rank realm, her aura is still leaking out a bit.

Giving a light hug, Rex nodded his head, "Yes, the matter has been dealt with" he replied.

But as soon as he said that, the expression on his face changed, "But new problems have appeared, there is no time to waste and I can't do this alone. As the Female Alpha, I need you to become my representative. Can you do that?" Rex asked.

"Anything, I'll do anything for you" Adhara replied with a serious tone.

It's not a regular thing for Rex to be needing help, this time is one of the few times he did that and she swore to always help him in dire times. "Gistella is struck by a curse, Naela said that there's a Cleric in the Dark Elves' territory called Qonvale. I want you to make a visit to the Dark Elf Kingdom"

"Bring Flunra with you, the rogue cursed creature is still out there" he added.

Upon hearing this Adhara nodded her head firmly, Rex has once told her that she needs to also be good at this kind of thing since she has the ability to see others' emotional aura. It's a tool that greatly helps her in reading through people.

Politics should be her forte, and this might be the start of her path to being like that.

Adhara then asked before she depart to the Dark Elf Kingdom, "What are you going to do?"

"I'm going to resume my training, Kyran is still the top priority" Rex replied without any hesitation, he was determined to master the Brutal Impulse as soon as possible. If the time limit is reached, then he has no other choice but to take the risk.

Just as she was about to leave, Rex suddenly grabs her arm.

Looking back in confusion, Adhara tilted her head with her eyebrows creased together. But Rex then said to clear her confusion, "It's dangerous out there, and I don't want you to be hurt. So I'm going grant you something that will ensure your safety"

"Since you are my Female Alpha, I'll need you to represent me accurately. I'm going to give you the Herald Mark..."
