The Invincible Full-Moon System

Rex scans the surrounding with hawking eyes, he saw nothing but rocks and water dripping from the cave\'s ceiling.

He looks up and saw many stalactites on the ceiling, he then looks at his claws and thinks for a moment,

After looking at his claws, a smile crept onto Rex\'s face as he got an idea before he vanished from his spot.

Meanwhile,

"Check every corner of the place, I want that Werewolves to be caught", a man said after arriving at the circle spacious place.

He seems to be the leader of the FAA and he looks around the place with a frown,

There are many holes around this place and he can\'t possibly track each of the holes by dividing his people into groups, it will only lead to their deaths.

"Sir Marcus, There are no signs of which holes they have gone into", one of the FAA members said, he shakes his head while looking at the holes.

Many of the other FAA members are looking around trying to find clues,

Their hands are ready with their gun, and they\'re on full alert because their target is Werewolves who excels in everything except for magic.

Marcus then commanded, "We should at least get one of them, there\'s no other choice besides splitting into four groups"

"And also, don\'t engage with them just locate them and report back to me", he added.

After saying that, Marcus assigns each people to a group.

Marcus divided them into a group of four which consists of 5 people that have a rank five Awakened leading them,

They then went to a random hole to search for the Werewolves.

While they separated from each other, a shadow can be seen crawling on the ceiling before he enters the hole where group one got into.

Marcus suddenly looks back with a frown, he suddenly senses something.

He\'s exploring a hole by himself because he\'s confident in his skill, and he frowns when he suddenly feels an aura appear before it disappears again.

\'Did I sense it wrong?\', he thought with a frown.

In the other hole,

Group one is lead by a guy with long brown hair, his sharp eyes are looking at his surrounding cautiously, "Keep an eye on the rear, there might be a hidden hole"

The group moves fast, they\'re all Awakened and their movement is fast.

Unknown to them, Rex is following them from behind.

When the FAA members come to the circle spacious place, Rex is on the ceiling hanging by the claws of his four limbs.

He\'s hiding behind a stalactite on the ceiling just enough to cover his body.

Rex kept silent and watch the FAA members but he avoid looking at the leader for too long.

It is a very risky choice because anyone that looks up might\'ve just noticed him there, and his hulking body is not on his side right now.

But thankfully, the system is there.

Rex bought an Aura Cloak Elixir that he bought from the system, it will hide his aura no matter if it\'s his Awakened aura or his Supernatural aura.

He bought it for a painful price, but it\'s okay if the elixir can help him.

Rex scans group 1 and finds that all of them are just rank four with the leader being mid-rank five, it will be easy for him to take them all out.

Even if he\'s not in his Werewolf form, he can fight them head-on.

With that in mind, Rex then began to move.

He dashes to his right and activates his spell,

The leader of the group kept moving forwards without even looking back, they think that they\'re hunting for the Werewolves.

But it is them instead who is currently being hunted.

Then, the leader suddenly notices that the ground turns black suddenly.

"HALT! Prepare yourself! We can at least fight one of them", the leader shouted as he sense something is coming, he can feel the fluctuating lightning mana underneath his feet.

He even frown when he felt the mana, there\'re not many Werewolves that can use magic.

The cave is dark, the Fire Elementalist only makes torches.

Only one of them is a Fire Elementalist, and the torches he can make are only so much.

Rex\'s fur is pitch black, he didn\'t even notice that his fur is even darker than the last time he turn into a Werewolf.

It will be hard to see his body with this lighting, Rex has the terrain advantage.

Two people gather metal mana on their hands, as soon as something attacked them then they will be ready to defend anyone.

One of the Water Elementalist is in the middle, while the Fire Elementalist is maintaining the torches beside the Water Elementalist.

The leader is a Wind Elementalist, and he already summons a wind spear in his hand.

But then suddenly, "Hmm?"

The wind spear the leader summons suddenly becomes hard to control, it struggles to maintain its form as if something is disturbing it.

He then looks below his feet and saw a black line of mana connected to his wind spear.

Then suddenly,

"AARGHH!!", The Fire Elementalist suddenly vanished from their vision.

They didn\'t even see the black shadow that takes the Fire Elementalist to the side, it was so fast for them to see anything.

Only the cries of the Fire Elementalist can be heard,

The leader looks to his left and saw the Fire Elementalist\'s neck is already clawed.

Fresh blood spilled from his torn neck like a fountain, it makes the leader widened his eyes in shock as he thought that their group can handle the Werewolves.

The Fire Elementalist choked on his own blood before the torches surrounding them vanished.

"Re...Retreat!!", the leader said in fright.

The cave becomes pitch dark, they literally can\'t see anything.

Many of the Awakened started to panic, they fire their guns aimlessly.

The leader rushes to this hole in confidence with the thought that he can win, it would make his standing higher if he manage to kill a Werewolf.

But that is only in his imagination, killing a Werewolf is not easy.

Especially if that Werewolf is Rex,

The group of five people got dispatch easily, there\'re only two people left including the leader.

Only screams of horror and pain can be heard from the leader\'s surroundings, the others got mercilessly killed by the Werewolf.

All of the others already got snatched by Rex and killed, he did it so easily that he even shocks himself with how much power he has during this state.

\'If only I can control the transformation\', Rex thought with a sigh.

The remaining people run to the other side fearing for their lives,

The leader wanted to use his communicating device but the signal in the cave is weak, it didn\'t reach Marcus.

Rex can only smile from the dark as he sees the remaining people run.

He then waves his hand before the black ground spat black lightning, it gripped the remaining people in their spot.

Even the leader can\'t do anything to destroy the black lightning.

It\'s like a chain that chained them to their spot, and their attack is like a dull knife trying to cut through a steel chain.

The leader struggles to break free, but then,

He saw two red blazing eyes from the pitch-black cave, it appears out of nowhere.

Just from the position of the red eyes, the leader knew that it is a Werewolf twice or even thrice the size of him.

Then suddenly,

The red eyes flash making him feel his power leaving him, his body is frozen on the spot unable to move.

Rex activates his Alpha Intimidation and stuns both of them.

Lightning cracks on his fingers lighting up a sliver of his face,

The leader and the remaining FAA members look at Rex\'s grinning face in horror, the devilish grin Rex has on his face got etched onto their brains.

And even after their chests are pierced, the smile is the only thing they remember until they died.

After killing group one, Rex stands up and looks to his back.

\'Three groups more to go\', Rex thought before he vanished in the pitch darkness of the cave.

Just after a couple of minutes of killing the first group, another wails and screams of another group can be heard filling the cave.

It happens to the other group as Rex killed them all.

The fourth group is the last,

Rex didn\'t want to fight Marcus because he knew that he would lose against him, a rank six Awakened that just assimilate with a spirit is not to be underestimated.

Even if Rex can still remain calmly standing in front of a rank six, it\'s a different story if he decided to fight against one.

He will completely be obliterated,

Rank six Awakened is not only a higher rank than rank five, but they also got a very powerful spirit that might multiply their power by 2, 3, or even more!

So fighting against Marcus is off the menu, even if it costs him the Sudden Quest.

The last group of FAA is in the same hole where Adhara dashes into, they pick the right hole to pursue Rex and the others.

But picking the right hole doesn\'t mean they will survive.

Rex already arrives at the back of the group and he also activates his Black Field Orko skill, he already felt the strain of using this spell too many times.

His everlasting mana for the first time is low, and he can\'t keep this up for long.

It is a foolish move from Marcus to ask the others to split, it only serves Rex\'s purpose better for taking them little by little.

The ground turns pitch black, Rex already activated his skill.

The last group has three Fire Elementalist on them, so it will be harder for Rex to take advantage of his night vision ability.

But when he saw one of the guys in the group, Rex widened his eyes.

\'I recognize that guy, where did I see him again?\', Rex thought as he look at the guy, he felt that the guy is very familiar.

Then, he remembered something, \'That is Argus!\', Rex thought in surprise.

Argus is the guy that rescued Rex from the Trickster Spider Anansi, he\'s the one that argued with Rex about the mission difficulty mistake by the FAA.

Seeing that guy, Rex smiles evilly.

He saw that the guy is stuck at peak rank five, he didn\'t grow at all from the last time they met.

It shows Rex how hard it is to find a spirit to assimilate with.

Rex activates all of his enhancement skills including the yellow Force, he almost becomes two times stronger than before.

Even if he\'s weakened by the Yule Moon, it will not be a problem for him to beat a rank five.

His Awakened power is no match for a rank five Awakened but his physical abilities are off the charts, and that alone can make Rex kill a peak rank five.

When he killed the first group leader before, the Black Field Orko works because of his higher-rank element and also because the leader is scared.

If not for it, he can break free from his black lightning.

Rex stomps the ground hard and pounces at the group of Awakened like a mad wolf, he recklessly attacks them from the back.

SLASH!!

His claw manage to catch one of them off guard, Rex\'s claws instantly ripped his stomach open.

The guy didn\'t even realize what happened until he got slashed, his eyes widened for a second before it turns lifeless.

From all of the torches around them lighting up the place, a third of it dimmed down after Rex killed the guy.

"Everyone retreat!! Report back to Sir Marcus!", Argus shouted decisively.

He creates an ice barrier around him to protect him from Rex\'s attack and dashes away, the others also defend themselves and run away.

They also fired at Rex while running away,

The bullet is imbued with elements and some hurt Rex, but his regenerative ability is stronger.

Looking at this, Rex smiles a mocking smile.

Rex\'s body started to blitz with lightning, in a flash,

BLITZ!!

His body turns into a black streak of lightning as he punches through a guy with a fire barrier around him, his fist is imbued with Force Beam as he punches through the fire barrier.

BOOM!

"KUAKHH!", the guy splurted out blood as a gaping hole appeared on his chest.

It came to him as a shock as he saw Rex\'s fist pierced through him, he looks towards Argus helplessly before he fell to the ground.

Rex looks at Argus with a nasty grin, "I remember you...Argus...", he said with his baritone voice.

Hearing this, Argus got goosebumps all over his body before he dashes away like a madman.

He kept running to the hole\'s mouth without looking back, and not long he finally realized that he\'s left running alone.

The others are gone, he\'s the only one left standing.

\'What the fuck? How did that Werewolf know my name?\', Argus thought in disbelief.

Out of all his days living in this world, not even once has he ever talked to a Werewolf nevertheless tell them his name.

He\'s not arrogant enough to think the Supernatural place a bounty on him too.

But there in front of his eyes, the Werewolf not only said that he remembered him but he also know his name.

Then suddenly,

BAM!!

The ice barrier surrounding him suddenly got bodied by something as he got flung crashing to the walls, his head was hit so hard that he felt dizzy.

Without giving another breath,

CRACK!

"ARGHH!!! MY LEG!!", Argus cried out in pain, his right leg got stomped by Rex and broke instantly.

The grin on Rex\'s face brings terror, Argus looked at Rex\'s horrifying look.

Rex can see a bleak aura coming out of him, Argus started to feel fear, "Do you remember me, Argus of the FAA?"

"Who...Who the fuck are you?!", Argus shouted helplessly.

Rex didn\'t answer his question, "I told you, I remember everything", he said with a grin.

He then raises his hand in front of Argus\' vision as his claw becomes longer and sharper, it makes Argus hoped for living almost snapped.

Rex points his claw to Argus\'s heart, but then suddenly, "STOP!!"
