The Invincible Full-Moon System

She is despairing in the face of Rex who is in his half-werewolf form, 'Why did I bring him here? I'm going to get killed now, but what's there to live for? Maybe this is for the best'

But just as she closes her eyes surrendering to the impending death,

CRASH!

The window makes an explosive arc sending shards of glass everywhere when Rex jumps through it, some of the shards are heading straight toward Rosie.

Rosie's eyes widen in surprise,

She then quickly turns her head away and covers her head with her arms in reflex upon seeing that the shards due to Rex jumping out are heading towards her.

After blocking the shards, Rosie gets up quickly and looks out of the window.

Rex is running away heading towards the forest like a beast,

Seeing this, Rosie was a bit surprised since she realized Rex manage to quickly snap out of his state and leave the mansion, her eyes flickered with a sense of relief and also curiosity as she gaze at Rex's disappearing back.

'He really is a human, there are no Supernaturals that hesitate in killing human'

'But what happened to him?', Rosie thought with a frown.

After Rex's back disappeared into the forest, Rosie looks at her back before she smiles wryly seeing the training room is full of claw marks left by Rex.

She puts her hands on her waist before biting her lower lip, 'How do I explain this?'

------

Igniting the world with a new light, the sun rises with elegance.

The golden light prickles everything it touches as Rex's eyes move under his eyelids in discomfort, he then slowly opens his eyes and was greeted by the sun.

Rex raises his hand to block the sunlight while adjusting his eyes to his surrounding.

After a moment, he slowly gets up from the ground.

"Urghh...", Rex groans in pain after feeling that his entire body is hurting like a broken twig.

He touches his right ribs with his right hand feeling the most pain in his body is there, "It hurts! I think it's broken", he whimpers.

Even after standing up, his head is still dizzy.

Rex tries to remember what happened that puts him into this state, but then he suddenly remembered before his eyes went round.

The scene from last night slowly seeped into his memories,

"No, no, no... I'M NOT A WEREWOLF!", Rex shouted with tears starting to well up in his eyes, he cannot accept the fact that he is no longer a human.

He grips the ground with mixed emotions but anger is the most prominent,

The veins on his arms and even neck start to expand as he grips the ground stronger, "RAARRGHH!!", he let out a scream of despair.

Even though he doesn't want to believe it, he remembered what happened last night clearly.

Rex then slumps on the ground while grabbing his head stressing, 'How funny is fate? I hate the Supernatural but I turned into one that I hated the most...', he smiled pitying himself.

But then he also remembers something, 'The System?!'

A hologram notification appears in front of him as soon as he thinks 'System', another interface appeared in front of him which caught Rex by surprise.

<Congratulations on starting the path of Invincibility!>

Rex looks at the non-stop notifications coming from this so-called system, he looks at it and blinked a few times in a daze as he still feels this is surreal.

But he soon recovers from his daze, "I don't want this power! I won't become a supernatural! Get out of my body!", he shouted angrily trying to somehow get rid of the system.

No matter what the system is, Rex doesn't want this kind of power.

His hatred towards the supernatural has already seeped into his heart and even soul so naturally, he is not happy with this predicament he is in.

<Unable to Execute Orders>

Reading the notification makes Rex boils in anger, he picks out a broken tree branch with a sharp edge before he threatened, "If you won't get out of me, then I'll just kill myself!"

When he intends to kill himself right here and right now, his hands suddenly stopped.

A flash of the scene where his parents were brutally murdered by that Werewolf crosses his mind, and the devilish grin of the furred monster once again appears inside his head.

It's the grin that haunted his sleep ever since the death of his parents,

Remembering that particular Werewolf, Rex's breathing suddenly becomes heavy, he slowly puts the tree branch down reluctantly, 'I can't... I can't die yet', he thought.

Just as he lowers the tree branch, a single notification appears.

<To kill monsters, you have to be one>

It's a simple yet effective sentence that hit Rex to his core, he realized that his mind was clouded with hatred but now it becomes clearer.

What the system said, Rex started to believe that it was true.

'Yes, it doesn't matter if I become one of them. As long as I gain the power to kill them...that's all that matters', he thought, he finally decided to use this power for revenge.

Revenge for what that Werewolf did to his parents,

Rex's eyes spark with brutality and determination as he clenches his hands, 'I'll use this power to exterminate the Supernaturals, and after I succeed... I will kill myself'

With that, Rex stands up before he asks, 'System, Are you really going to make me stronger?'

<Yes>

'This power, Can I do whatever I want with it?', Rex asks with faint anticipation.

<Yes>

After reading what the system said, his eyes start to blaze with killing intent.

He smiled disturbingly thinking about the massacre that he will do but he then suddenly thought of something, 'If you can give me Supernatural power, doesn't that means you are on the Supernatural side?'

'Does it matter which side I'm on?'

<The user can do anything with the power you will soon possess, no matter which side the user is on, killing Humans, killing Supernaturals, all are allowed and will be rewarded>

Reading this, Rex smiled mischievously as he can't help but become exhilarated.

With the matter with the system out of the way, Rex then looks around the place which is still destroyed from the fight he had with that Cyclop, 'First thing first, let's get out of here'

After just taking a step, he stopped again feeling his ribs are hurting, 'It really is broken...'

<Estimation of Recovery: 9 Hours>

'It sure is good to have regenerating abilities', Rex thought, he then decided to go back home.

There are no mishaps that happen during his journey back home though everyone seems to give him disgusting glances, and he knows fully why they are giving him these glances.

'My shirt is torn off from the transformation, I cannot judge them', Rex thought.

Because of his torn clothes, Rex looks like a beggar and he's even surprised that no one gave him any money yet with how his appearance looks right now.

While walking back, Rex thought about what happened last night.

'Oh yeah! I gotta find Rosie, I need her to keep what she saw a secret if I want to stay in the human territory', Rex thought, but then suddenly,

<Sudden Quest!>

Due to the user going berserk from the Blood Moon, Rosie has posses the information of the user being a Supernatural. Make sure that Rosie will keep the user's identity a secret to avoid future problems!

Quest Reward: 1000 Exp, and 1 Skill Upgrade

Failure: You will be hunted by the Acosta Family

Time Limit: 14 Days

'Hmm? Did I just trigger a quest by thinking about Rosie? Regardless if it's a quest or not, I need to make sure Rosie didn't tell anyone', Rex thought while reading the Sudden Quest.

After dwelling on his thoughts, Rex didn't realize that he was already in front of his house.

The house in front of him looks like an average house, it is a two-story house with three bedrooms, upon entering he was greeted by a comfortable living room with a white sofa, a TV hanging on the wall in front of it, and a fireplace just under the TV.

Rex feels nostalgic while looking at the place after all he's been serving in the military for years.

Hearing the door is opened, his mom, Mrs. Greene pokes her head out of the kitchen.

"Oh, Rex! Where have you been?", Mrs. Greene asks with a playful smile, she studied Rex from head to toe and saw Rex's appearance that is very different from yesterday.

Rex thought of a reason before he replied, "Rosie suddenly feels sick so I escorted her home"

He forces a smile trying his best to lie his way out,

But from the teasing smile that is becoming more evident on Mrs. Greene's face, it seems she didn't buy it, "Really now? I can clearly tell that you're lying".

With suspicious eyes, Mrs. Greene approaches Rex who is standing stiff.

Contrasting Rex's expectation, she suddenly tugs her elbow while she whispers playfully, "I know that teen this day is bold but really? It's the first day you met her, and she already brings you to her house?"

"WHAT? No mom, I just esc-", Rex's face reddened wanting to rebut but his sentence got cut off.

"Yeah, Yeah! You don't have to lie to me. But seriously, how fierce is she that even your clothes didn't survive the night", Mrs.Greene added teasingly, she seems to like seeing Rex's stiff expression as if he got caught doing something bad.

"MOM!" Rex shouted feeling embarrassed.

Without waiting for another word to come out of Mrs. Greene's mouth, he runs into his room and closes the door leaving behind his laughing mother.

After he got into his room, Rex jumped onto his bed face first.

"I'm tired, it's good to be home", he mutters but then he remembers that he still has some rewards that he got from the Transformation reward.

Rex then calls out the system and quickly goes to the Stat tab,

<Stats>

<Rex Silverstar>

Level: 4 (20/300)

Race: Half-Blood (Werewolf)

Full-Moon: 27 Days - Dark Moon

Berserk: 60%

Sanity: 58%

Mental: 2

Strength: 12

Agility: 10

Endurance: 9

Intelligence: 0

Attributable Stats: 9

<Average Human Adults have 5-7 points for each stat except for Intelligence>

Looking at the stats, Rex noticed some changes.

Rex noticed that the Full-Moon section turned from Blood Moon into Dark Moon, 'So this section indicates when is the next Full-Moon but what is its effect? Do I need to experience it first before knowing the Dark Moon's effect?'

'Whatever, let's just try to avoid transforming like yesterday', he thought.

Aside from the changes in the Full Moon section, the berserk and sanity stats have both increased tremendously, but Rex still doesn't understand the meaning behind those stats.

'I only know that sanity stat will be measured during Full-Moon, I think it got something to do with the transformation', he thought, but he then turns his attention towards the other stats.

Strength, Agility, and Endurance have increased just like the System said but his intelligence and mental didn't even budge, he also got 9 attributable stats that should be able to be allocated to the other stats.

Rex tries to add it into intelligence first but quickly got denied,

<Unable to raise Intelligence Stat>

'How about Mental stat', Rex thought as he tries to increase his mental stat, but surprisingly it can be added, unlike the intelligence stat.

For the Mental stat, Rex also remembers that it will be added to his sanity stat during the Full-Moon.

Rex doesn't want to transform needlessly again so he will need to focus on this Mental stat, he puts another three points into the Mental stat before his eyes land on the physical attribute stats.

'So that leaves us to Strength, Agility, and Endurance. Hmm...Which one to raise?'

But after thinking for a moment, Rex rubs his head feeling a bit tired, 'Too much thinking today, I'll just add the rest of the attributable stats to the Strength stat'

Rex's stats now looked like this,

<Stats>

Name: Rex Silverstar

Level: 4 (20/300)

Race: Half-Blood (Werewolf)

Full-Moon: 27 Days - Dark Moon

Berserk: 60%

Sanity: 58%

Mental: 6

Strength: 17

Agility: 10

Endurance: 9

Intelligence: 0

Attributable Stats: 0

<Average Human Adults have 5-7 points for each stat except for Intelligence>

Rex looks at the updated Stats tab and is satisfied with it, his eyes then started to blink heavily feeling the tiredness that he felt which was probably caused by yesterday night's transformation.

But just as he wanted to sleep, he remembered the reward he got from the system.

'System where do I find the Talon thingy', Rex asks inside his head.

<Items that are rewarded will be automatically stored in the Inventory tab>

Rex then proceeds to open the Inventory tab, and he found one item lying there.

He decided to click on it to see if he can find the item's description, luckily another tab opened just as he has expected right after he clicked the item.

<Talon of Ballistic Garuda>

It's a talon of a third-rank mutated animal, the talon is as hard as Iron and can be used as a material to make a weapon. It can also enhance the user's claws.

'Enhance my claws? How do I do that?', Rex thought.

But first, he decided to bring out the Talon of Ballistic Garuda by clicking on it twice.

Magically, a big talon as big as a soccer ball appeared in his hand out of nowhere.

Rex lifts up the talon and studied it closely,

The talon is black in color and as heavy as steel, it glistens under the sunlight from the windows and it gives off a sharp feeling.

After inspecting it, Rex brings it closer to his nails before a notification appeared.

<Do the user want to use Talon of Ballistic Garuda to enhance the user's claws?>

Rex immediately answer yes inside his head,

Just after he answered the system, the talon suddenly merges into his nails, the process is a little bit painful but Rex suffered through it without a sweat.

Then another notification appeared,

<Obtained 100 Claw Exp>

<Your Claw has Leveled Up!>

<Increase Strength stat by 3>

Rex opened his mouth wide in shock, 'I can raise my claws level?! Wait, doesn't this means I can also increase other body part levels as well...?

'That's pretty OP!'
