Grand Duke of the Heibern House

＜Chapter 64＞

“… … Mdra’s magic?”

The great drink god Medra.

He was the highest level demon among the Eight Absolutes and the Eight Great Demons in the Demon Realm.

Having existed since the first Pandemonium War, the ‘Age of Trepidation’, he is a living fossil to the demons.

But, is the magic of Heirodes the black magic of an existence standing at the apex of the demon realm?

The process of approaching convergence from the method of manifesting mana, the circuit configuration for each stage of transition, and the system for forming and strengthening mana itself were clearly white magic.

In particular, traces of Theamaras’ representative theoretical achievements, ‘the immutability of symmetry’ and ‘the paradox of control’, were everywhere.

The magic that thoroughly analyzed the mana of the human world, not the real mana, was very clear.

“No matter how much I think about it, it doesn’t make sense? Anyone can see that this is white magic, right?”

– No wonder it looks like that. But look closely. Is that all there is to it?

To describe white magic in one word, it is ‘wisdom’.

On the other hand, black magic is ‘mind’.

Clearly, the magic of Heirodes did not have the feeling of completely melting mana with an overwhelming mental system.

-This is just releasing his magic to suit human white magic. Take away all the theoretical system and attributes of magic formulas and analyze only the flow of magic power itself.

“what?”

Look at the book of magic again.

As Gyrobel said, Ruin excluded all theories and attributes and pursued only the flow of pure mana.

Soon, Ruin’s pupils rapidly expanded.

“Diffusion deterioration type black magic… … ?”

-okay. This is his burning magic, ‘Kiodera’. Transformed to fit the theory of white magic.

Gyrobel was trying hard to disparage it because it was just a modified magic, but Ruin knew about it.

Heirodos’ ‘Fire in the Manger’ was a more advanced form of magic.

It was a magic that harmonized with white magic and amplified its power even more, showing a truly amazing reinterpretation.

Luin’s expression changed suddenly.

This magic book of Heirodes is the clue he has been longing for.

A fusion of black magic and white magic.

However, he never thought that the legacy left by Gyrobel’s nemesis, the great demon Medra, would be a clue.

The images that have always been distorted are finally beginning to form.

roar-

The fire of the manger, the terribly blue fire, bloomed in the world of images.

Even though it was the heat of the image, the illusion that the whole body was burned by the fire was caused by the distant heat.

Soon, Luin’s expression changed strangely.

“A human being can perform this kind of magic?”

The manger fire was never accessible without an understanding of black magic.

This Heirodos magic has passed the verification of countless schools and has been recognized as a theory.

That meant that the white mages understood this magic, which was difficult for Ruin to accept.

-It means there are more wizards among humans who have studied the dark magic of demons. It seems that this Gyrobel underestimated humans too much.

Ruin was so surprised that there could be a human who understood the magic system of the great demon god Mdra.

‘Well, me too… … .’

Gyrobel’s contractor.

There was no reason why Medra couldn’t make a contract with a human.

Tup-

Unfortunately, it was too late.

If he immersed himself in the magic books any longer, there was a risk that the routine he had been working so hard for would be broken.

Ruin got out of the Wisdom Library and headed to the dormitory.

* * *

Adrena, who had been staring blankly at the playground, was checking the clock tower as if she couldn’t believe it.

“to… … ?”

The hour hand of the clock tower, glowing with luminous light, pointed to the unmistakable 4:00 AM. Even after washing his eyes and looking for him, Ruin was nowhere to be seen.

“Ah! I don’t have that guy! No!”

But why is this so enjoyable?

Seeing the guy who managed his time thoroughly collapse, a strange feeling of pleasure spreads throughout his body.

“Heh heh! He was a human too!”

A precious pleasure that can only be cherished by one who has observed Ruin for a long time.

Ahh! did you sleep late?

Or am I not feeling well anywhere?

It doesn’t matter. It was confirmed that the guy was also a person who couldn’t help it. Now you will never be arrogant in front of yourself.

I feel like I’ve caught a weakness!

Time passed like that, and Ruin didn’t show up until 8 o’clock in the morning.

It was only when the morning bell rang and morning classes were running out that Ruin appeared in the classroom.

Adrena, who found Ruin, approached him with a happy smile.

Took-

Adrena was still smiling strangely as she slapped Ruin on the shoulder.

“Eh, did you oversleep at all? Or did I get sick somewhere? It’s strange. Aren’t you that kind of person?”

Ruin forcibly looked away from Adrena’s crescent-shaped eyes.

“Why are you shy? Is it something you don’t understand? Alas, even if a person procrastinates for a day… … .”

Ruin started to shake little by little.

“That mouth-”

Ruin tries to say something but just keeps his mouth shut.

A lot of time was delayed because of the conversation with the suddenly awakened Sahol.

In addition, it was already past 3:00 in the morning when I got out of the Wisdom Library because of the reinterpretation of ‘Heirodosugi – Theory of White Magic’.

I tried to stick to my original routine, but I risked ruining my whole day with the condition that I couldn’t sleep for even an hour.

So I gritted my teeth and skipped my morning run.

“My mouth? Did you put anything in my mouth? After being stretched out, did you just lose control of that desire? All of a sudden, my lips feel so tempting—”

Ruin was well aware of what this woman was weakest at.

“With 100 li. Settlement later.”

“receipt.”

Adrena forced her mouth shut, but still smiled with her eyes.

-Aren’t you the one who values the efficiency of time more than anyone else anyway? Magic is important, but I think breeding is also important for mortal humans.

-If you are a human, the clear breeding standard is the buttocks, right? That red-haired female seems to be enough. Now that this has happened, what do you guys think?

Ah, if he really has a body, I want to rip his snout off.

Well, what would you expect from a guy who vomited eggs in his stomach?

Demons who have lived as uncivilized hermaphrodites have no way to understand the noble love of humans.

Ruin bit it.

‘I can’t help it because I want to see the chest open like that. this evening… … .’

-sorry.

Compromise with reality at a speed that is unbelievable for a demon, the absolute god of the demon realm.

When Louin sighed and sat down at the desk, Chiron came over and sat down next to him.

“Howdy. good morning.”

Then, Shiron took out a wide wooden plank from his bag and fixed it to the left side of Ruin’s desk.

“… … What are you doing?”

Chiron lowered her stance and glanced to the left.

“They are already suspected by the dean of the department as following the southern school. Don’t even look at those women from now on, Ruin.”

“… … .”

In the morning, I was tired in many ways.

It wasn’t just the routine that got messed up, it felt like this f*cking life in the magic department wasn’t going the way we wanted it to.

While Ruin was staring at Shiron with a frown, Professor Gary Eldos appeared in class.

Professor Gary Eldos also looks at himself with an unwavering gaze as soon as he appears.

Ruin shakes his head violently and comes to his senses.

In that way, Ruin made a promise several times in his heart that he would never do anything conspicuous again.

Even if the archmage’s self-consciousness can’t tolerate stupid magic theories.

No matter what kind of words hurt my pride, I will keep my mouth shut unconditionally.

-… … .

Watching Ruin suddenly act like a real boy, Gyrobel felt strange.

He looks like an undergraduate who is really living an academy life.

Ruin’s sharp and cold appearance in the family was still vivid, and it was inevitable that it would be very foreign to Gyrobel.

Have I forgotten the sadness of the past?

Or is he unknowingly being assimilated by the liveliness of the cadets?

Professor Gary Eldos, who was teaching on the podium, was smiling heartily.

“Good morning, cadets. Today, I’m going to talk about ‘orbital inertia of magical power’.”

At the same time, the cadets’ expressions darkened like one body.

Classes in the Faculty of Magic couldn’t be easy, but among them, the level of difficulty in the ‘Beginner’s Magic Theory’ was extremely high.

The biggest problem was that the nature of the power called magical power was so complex that even if there was one perfect theory and law, it could not be applied to all other techniques.

In particular, the various inertial properties of magical power varied greatly depending on the amount and purity of mana, the caster’s cognitive ability and magic state, the level of telekinetic power, and the characteristics of the mental system.

There were many students who questioned why they had to learn it when it was not something that they could immediately apply to their own techniques.

“Judging by the facial expressions, it seems that you have lost your soul in the ‘non-inertial reference coordinate system’ in the previous lesson.”

The complexion of some of the cadets turned to an earthy color.

To the extent that infinite respect arose for the first-class cadet seniors who learned all these tremendous theories and advanced first.

“But what? If you don’t understand the nature of magical power, it will be messed up from the first step of constructing a circuit. Fortunately, it will be more interesting than the last class, so stop expressing yourself.”

At that time, a sudden gust of wind rose from Professor Gary Eldos’ right palm.

Whoops-

“Can you find out?”

It looks simple, but it is a magic that can never be performed at the level of cadets with no rank.

“This is a typical mid-level magic wind screw that utilizes the orbital inertia of magic.”

The cadets stared blankly at Gary Eldos’ wind screw, which was spinning like a living wind.

“When the magical energy starts to accelerate moderately on a flat trajectory, at some point it naturally moves at a constant speed. This is the orbital inertia of magical power. The problem is the standard for judging this ‘proper acceleration’.”

The wind screw, the gust of wind lingering in the palm of Gary Eldos, was growing in size.

“The inertial frame of reference that each person perceives is different. This is because the gaze of the observer who measures the state of motion is different. This is a matter of the senses, but at the same time a contradiction in theory.”

“Ahh!”

“Ohhh!”

Cadets who are gradually starting to fall in love.

“In the case of chlorine-type or ice-type magic that implements magic formulas through contraction and expansion of magical power, there is still a chance even if the magic is temporarily disturbed.”

Gary Eldos suddenly looked at Ruin.

“But if you don’t fully understand the orbital inertia of magical power, the constant velocities of all orbits will exceed the angular displacement.”

Whoaaagh!

“Ah!”

“evil!”

The activated gusts of wind grew so large that they seemed to consume the classroom, then dissipated into the air.

Professor Gary Eldos shakes off his hand and looks at Ruin.

Ruin suddenly lowered his gaze to the desk.

“That’s why, if you make a mistake with windmill magic, you can’t sweep it back. This is the reason why the difficulty level of wind-type magic is the most heinous among elemental magics.”

Professor Gary Eldos’ eyebrows twitch.

“But even so, if the inertial frame of reference is regarded as a matter of the senses of a magician, there is no need for this class. How should I resolve this contradiction, Cadet Ruin?”
