Chapter 24
Translator: True Detective
### Chapter 24: Resolve
Two days before departing for the Academy.
I sat at my lab desk, resting my chin on my hand, and fell into deep agony.
*'Is it okay to take Yveline with me.'*
The reason Yveline in the original work terribly hated the heroine Yuna is simple.
The long-standing tradition and cliché of romance fantasy.
Her lofty pride as a Duke's daughter collapsed feeling an inferiority complex towards the commoner Yuna.
But what about Yveline in front of me right now?
To be honest, the feeling itself is different from the original work.
Inferiority complex?
I don't even know if she feels such a thing.
*'It seems she doesn't care about anything other than me and magic these days.'*
But I can't completely ignore the deterrent force of the original work either.
According to the advice of Senior Selene and Eleanor, an entity called Causality exists in this world.
Even if the existence called me is a variant that escaped Causality.
It's unknown when the restorative force of the world might operate and push Yveline back into the tragic flow of the original work.
So I tried to detach her from the stage of the original work as much as possible.......
"I'm going too."
"You stay here. I'll drop by the lab every weekend. Because I can't reside at the Academy constantly either."
At my words, Yveline's hands packing her luggage stopped.
She slowly turned her head and looked at me.
"It'll be much more helpful for you too if I go along? And...... I, hate being away from you."
Yveline added.
"What would I do staying here when you're not around. With my status, digging up information inside the Academy is a piece of cake. The name Estal isn't just a decoration, you know?"
Hmm. Honestly, I can't refute it.
Yveline's status isn't some dog's name.
She is the Princess of the Estal Duke family, the best among the prestigious magic families of the Empire.
I just forgot because I got used to it.
She is an existence everyone looks up to.
The Academy's iron rule of not looking at status?
Such a utopia cannot possibly exist in a romance fantasy world.
While I dig for information hard.
Because she could make people open their mouths at once just with the status of a Duke's daughter.
*'Hmm.........'*
Agony was short, and judgment was fast.
*'Let's take her.'*
I can at least keep an eye on her if I keep her in front of my eyes.
It's unknown what kind of accident she might cause if left alone.
"Got it. Let's go together. Instead, you have to listen to me well."
When my answer fell, Yveline's expression turned bright in an instant.
Yveline grabbed my arm abruptly and smiled as if satisfied.
"Yeah. Of course."
Then she leaned her head slightly on my arm.
"I'll clear away all the things that get in your way when we go to the Academy."
......What are you saying.
I'm worried already.
****
[Rihan. Why are you suddenly grabbing a pen?]
At Eleanor's question, I quietly spread a piece of paper.
"I'm going to solve a problem after a long time."
I needed a justification.
A guy nominally called the Chief Researcher of the lab suddenly crawls into the Academy as a freshman one day?
This doesn't add up.
No matter how much Duke Cassian is backing me up.
Baseless preferential treatment is bound to cause gossip.
The Duke's face is also a problem, but above all, I had to consider the external image of the laboratory I belong to.
It means there must be a legitimate academic reason, not just going to play.
I brought out one of the so-called unsolved difficulties that Director Barman handed over to me while suffering a headache in the past.
[Rihan. To my eyes, it just looks like a crudely twisted ball of thread. Are the humans here struggling, unable to properly untie even such a trivial knot?]
To her, who stood at the peak a thousand years ago, it seems it's merely a crude puzzle piece.
And that was the same for me too.
"It doesn't unravel because they only approach it with magic."
Spinning the pen, I began drawing the flow of mana as lines on the paper.
The core of this difficult problem was how to maintain a stable formula within a chaos realm where mana swirls irregularly.
With general intuition, one would put in less mana to lower the density.
Or try to press it down with stronger magic power?
*'I just have to use the interference phenomenon of mana.'*
I approached differently.
If the phases of the waves generated as mana collides are overlapped in reverse, the energy cancels out and becomes a static state.
The so-called principle of **Destructive Interference**.
$A \sin(kx - \omega t) + A \sin(kx - \omega t + \phi)$
Here, by setting the phase difference $\phi$ to $\pi$, the wave converges to 0.
The fluctuating waveform of mana will meet the opposite waveform and quiet down like a lie.
I wrote down the formulas.
[......Oho. Not pouring magic power, but tying up the ends of the flow. Truly an approach from a different perspective.]
Eleanor recited lowly as if interested.
A short while later, the organization was neatly finished.
"Now, preparations are complete."
I picked up the completed formula.
***
The hallway heading to the Director's office with Celly.
Her gaze headed to the bundle of papers in my hand.
"Mr. Rihan, what is that? Because you've been looking at it with great concentration since earlier."
"Ah, this? A difficult problem regarding mana stability in a chaos realm."
"......Don't tell me you solved that?"
Celly's eyes began to sparkle.
"Um, could I look at it just once? I stayed up several nights over this too but couldn't get a grasp on it at all!"
"Well, I don't mind."
Celly's mouth, having received the paper, slowly opens.
Her pupils quickly scanned over the formulas.
"No, you interpret mana like this?"
Celly started muttering like a possessed person.
"So, not pressing it down by increasing magic power intensity but...... making mana collide with each other so it converges to 0? Goodness, this changes the dimension of mana efficiency?"
As expected, the position of Chief Researcher is not obtained for nothing.
She is picking out and understanding only the core of my explanation which could sound like grasping at floating clouds.
A genius-like sense.
I want to kidnap her to my lab right now.
[Rihan. That child has quite a good eye. To recognize your bizarre trick at once.]
Seeing her pass Eleanor's praise criteria at once, that says it all.
"Amazing, Mr. Rihan! This is a revolution!"
Leaving Celly chattering next to me behind, I stopped in front of the Director's office.
****
Before opening the door to the Director's office.
I lightly adjusted my attire.
*Knock, knock—.*
"It's Rihan."
As soon as the knocking sound ended, a voice telling me to come in was heard from inside.
As soon as the door opened, Director Barman adjusted his glasses and showed gladness.
"Oh! Sir Rihan, what is it!"
It seems he has become too affectionate lately.
Now, just seeing me makes Director Barman's mouth corners twitch uncontrollably.
"Don't tell me you've already organized a new formula?"
I brought up the main topic without long words.
"No, it's not that. I'm going to go on a dispatch to the Academy for a bit."
The Director's complexion changed instantly.
"What? The Academy? Are you crazy! Right now our lab's stock...... no, reputation hangs on the tips of Sir Rihan's fingers! Where are you saying you're going!"
"Because of the ghost disturbance investigation."
"Can't we just call an exorcist or something for a mere ghost! No! Absolutely cannot go! I'd rather buy the Academy and move it next to the lab, but I cannot send you!"
When the Director was about to climb over the desk.
Celly, who was standing behind, threw a word coldly.
"Director, the Imperial Family has also started paying attention to this incident. There is intelligence that they might dispatch an investigator directly."
"......Th-That's a bit troubling."
"If we don't strike first, the entire lab will be pressured. If an audit or something pops up, isn't the Director the one who gets most annoyed?"
As the Director hesitated, Celly added as if driving a wedge.
"It's not like he's going to stay there permanently. He will solve it quickly and return."
"Still, to send two Chief Researchers......."
"I also have a mountain of work and Mr. Rihan is busy too, would we stay there long? Just consider it a light business trip."
At those words, the Director's pupils shake.
He looks relieved at the word business trip.
Not missing that gap, I pulled out my hidden card.
"I felt sorry to just go, so I solved the problem the Director was worrying about last time and brought it."
"Problem? How long has it been since you returned from the Duke family that you tackled a difficult problem......."
The Director received the paper with trembling hands, half in doubt.
His pupils, reading the first line casually, began to tremble.
"......Th-This can't be! Isn't this Verma's Last Theorem!"
**Verma's Last Theorem**?
I thought the name had a strangely familiar ring to it.
It seems to be the romance fantasy version of Fermat's Last Theorem which made the eyes of numerous mathematicians in my past life red.
Did that man also leave a rare absurd remark before dying saying the margin is too small to contain the proof so he omits it.
I replied casually.
"Looking at mana from a slightly different perspective than usual, it worked. The formulas fell neatly more than I thought so I jotted it down."
"Jotted down! You, do you know what you just did? You brought down the Wailing Wall that drove mages to suicide for hundreds of years!"
Director Barman's mouth corners go up.
"Go! Go! No, you must go! Go and show those Academy bastards clearly what kind of monster our lab's Chief Researcher is!"
I bowed my head lightly.
"Then, I will be back."
As we left the Director's office, Celly gave a thumbs up.
Now, preparations are complete.
