The Invincible Full-Moon System

'No, that's not possible. Unlike humans, Supernatural inherit their magic affinity from their bloodline, so there's no way they can use other Supernatural's magic', Rex thought, shaking his head.

Rex then thought, 'The higher-ups have probably considered this possibility, but the most likely possibility is some kind of mutation of the siren's magic that causes all of this'

While Rex was in thought, "HA!"

Rex jumped in surprise, Rosie startled him, "What are you thinking hard about? Let's eat!"

He felt annoyed but looking at the food, he then gulped and started eating without even paying attention to the girls.

After eating, Rex wanted to go back to his room.

He thought that his level is not enough and his progress will be slow if he relies on a field test from the university like before, he decided he wanted to buy a breathing technique from the system.

The day already turned dark, Rex wanted to bid his goodbye and head back to his room.

Just as Rex wanted to say his goodbye, Laura holds onto his hand and gives him another brown handbag.

She then shyly said while avoiding Rex's gaze, "Happy Birthday, It may not be much but I hope you like it"

Rex smiles, 'She remembers my birthday, so that's why I coincidentally found her here'

He then looks at the handbag and found a box in it, the box looks neat and lavish. He then opens the box and found a silver ring in it.

Laura then said, "It's a piece of battle equipment, it can enhance your physical abilities by 10%. Although it's not much, but I hope you like it"

"I like it! Thank you", Rex said, he then tries to wear on the ring when suddenly his fingers started to burn.

<Physical Contact with Silver, Your Stats is decreased by 30%!>

<You will suffer from immense pain>

Reading this Rex was shocked, 'What the? I thought Silver didn't hurt me, what happened?'

<Becoming a full-fledged Werewolf brings many benefits but also enhancing your weaknesses, Silver might not hurt a Half-Blood but it will be toxic for full-fledged Werewolf>

Rex forgot that he just turned into a full-fledged Werewolf, he smiles bitterly trying to hold in the pain.

Laura noticed Rex's stiff expression, she then asks worriedly, "Rex, you okay?"

"I'm fine!", Rex replied hurriedly, he then bids goodbye to the three of them and left.

Adhara on the sides chuckles, 'That's made of silver right? HAHA, that's funny', she thought.

Laura reaches out with her hands but stops mid-way, she then turns to her back with a complicated expression.

Adhara approach her and said, "Don't worry, I know for a fact that he likes your gift"

"You think so?", Laura replied.

Adhara then nodded assuringly which makes Laura's mood brightened.

Meanwhile, Rex is running towards the dormitory section.

'Shit, Shit, Shit, Shit! It hurts!', Rex runs to his room with all his might, he is afraid that someone will notice him tossing the ring away if he takes off the ring now.

So he decided to run as fast as he can to his room,

While he runs past the lecturer's room, Rex saw a commotion happened there.

A crowd of students gather outside the lecturer's room, Rex can even hear someone is shouting inside while breaking stuff.

"WHY CAN'T YOU DO YOUR JOB PROPERLY?! HOW DID MY SON DIE?!"

"Calm down Sir, it's a regret that your son died during the field test but it is completely an accident"

"RANK THREE SKELETAL DRAGON?! THAT THING CAN'T POSSIBLY KILL MY SON!"

"WHO IS IT?! WHO KILL MY SON?!"

"You cannot make a scene here sir, If you have any complaints please meet with the principal. We're only Lecturers here"

"USELESS BUNCH!"

BAM!!

The door opened and shut forcefully, a muscular middle-aged man storm out of the lecturer's room with clear anger on his face, his aura is leaking that gives immense pressure to the surrounding.

Based on his appearance, he is at least a rank-six Awakened or even higher.

The middle-aged man is wearing a red suit and tie, he excludes dominance and authority. On his chest lies a black tiger badge with a crown on top of it, it seems he's a master of a guild.

The middle-aged man storms out of the university with clear anger on his face, he left the university shortly after he got out of the lecturer's room.

The students outside started to gossip about the event,

"Is that the head of the Platchi family? Duncan Platchi?"

"Yes! It seems he's not going to accept his son death"

"I heard he reach late rank six, he then becomes the successor of Black Tiger Guild"

Rex hears the student's conversation and frowns, 'That's Lucas Platchi's father? This is troublesome. If that Duncan Platchi sent out an investigation, he will surely found that Lucas died because I broke his neck before getting stabbed by the Skeletal Dragon. I need to be careful', he thought.

Arriving at his room,

BAM!!

Rex closed the door forcefully, he then grabs the ring on his finger and tossed it away.

"Aaahhhh..", Rex moaned.

His finger turned a little black because of the ring, it also let out steam as if his finger is burning.

Rex goes to the bathroom and puts his burned finger on flowing water, it still hurts but not as much as before.

'That hurt so much! What does it felt like when I didn't have a 25% immunity against silver?', he thought, Rex can't imagine the pain Werewolves go through if they got stabbed by a silver object.

He then sits on the bed and opens the system,

Rex then quickly goes to the Shop tab, he then searches the breathing technique and instantly many techniques appear.

He scans through the list of techniques and found the big line of it, 'There's many techniques with different grades, low, mid, high, and supreme. There are two types of technique, the first one is the Full-Moon technique, it is a breathing technique that will enhance the absorption of Lunar Blessing during Full-Moon which brings huge Exp and mutation'

He then thought a little and continue, 'The second is a basic moon technique, it is a versatile technique that can be used in any moon. Although it gives less Exp and a lower probability of mutation, it can be used every night so it is a plus'

After a round of thinking about the pros and cons, Rex decided to get the basic moon technique, 'Although Full-Moon technique brings many Exp and Mutation, it only comes once or twice a month and that's not what I'm looking for'

After decided on which types of technique, he then started to look at the price of low, mid, high, and supreme Basic Moon Technique.

'Low and Mid is affordable ranging from 1000 gold to 10000 gold, high and supreme is basically out of my pocket right now', Rex thought, he then looks at his current gold.

There is only 390 gold left in his pocket, he then looks at the exchange rate of gold to dollars and found a 1:100 ratio.

'I have about four hundred thousand dollars right now, if I convert it all into gold I get about four thousand gold', after knowing his budget, Rex starts to search for a technique.

The basic Moon Technique differs from each other, there's a technique that can cause the user to be able to use elemental magic and there are others that can cause mutation.

After summing up the affordable mid-grade technique, he got the following techniques.

<Darren the Healer Breathing Technique - Mid>

Using this technique under the Lunar Blessing will give 300 Exp per hour of meditation, By chance, the user can also gain a mutation. The mutation will make the user's saliva contain healing properties.

<Almighty Body Breathing Technique - Mid>

Using this technique under the Lunar Blessing will give 200 Exp per hour of meditation, by chance, the user can comprehend earth elements and strengthen the user's body.

<Robust Will Breathing Technique - Mid>

Using this technique under the Lunar Blessing will give 250 Exp per hour of meditation, by chance, the user can gain additional Mental stats and strengthen your will.

Rex fell into deep thought, each technique has its own pros and cons.

'What I need right now is leveling up, so that kick the Almighty Body out which has the lowest Exp per hour. The second thing I needed is mental stats to ready myself for the next Full-Moon', He thought.

After deciding on his breathing technique, Rex converts $ 300,000 into 3000 gold.

The breathing technique costs 3300 gold,

Buying the technique left him with a 90 gold penny left in his pocket, Rex then summons the technique, and immediately a book appears on his hand.

The book is dark red in color, it has a wolf's head on the cover with a 'Robust Will Breathing Technique' black-colored writing below it.

Then suddenly, a notification appeared in front of him.

<Do you want to learn the technique?>

Rex looks at it in surprise, he nodded his head feeling lazy about reading when suddenly another notification appears,

<Learning Robust Will Breathing Technique will cost 90 Gold, Do you want to continue?>

'What the? 90 gold is exactly what I have left in my pocket, this System is a damn scam', Rex thought annoyingly before he pay the 90 gold he has left.

The red book on his hand transforms into a red light that zipped into his brain, Immediately after packed information about the breathing technique enters his brain.

Rex immediately understands the breathing technique,

He then left his room and headed to the rooftop, the breathing technique needs the user to be exposed to the moonlight.

On the rooftop, Rex found an empty seat near the fence where he used to sit.

The rooftop is more crowded than usual, some students just chat with each other, some lazily sitting around, some is playing with their elemental power, and some are smoking cigarettes.

But all of them have one thing in common, the gloomy vibe around them.

'It seems University life starting to pressure them', Rex thought before sitting on the bench.

He then asks the system, 'Will there be any effect while I'm meditating'

<No, Mid Basic Breathing Technique will not cause a disturbance in your surrounding>

'Then that means higher technique will cause disturbance', Rex nodded his head before he recalls the breathing technique and start his meditation.
