Sometimes, inspiration is unpredictable. When you desperately seek it, it's nowhere to be found. But when you relax, it suddenly appears.
Roger was in the Room of Requirement, where he usually conducted his magical experiments, flipping through a book.
It was one of the books borrowed from Professor McGonagall… As the deputy headmistress of Hogwarts, she had carefully selected these private collections with the hope of shaping the future. Every book she lent to the Seer was a valuable treasure, each contributing, to some extent, to Roger's understanding of the magical world.
This particular book was quite special.
"The Connection Between Soul and Brain"—a rare modern-era book among the vast magical literature.
The author wasn't a specific wizard; the book was credited to the "Department of Mysteries, British Ministry of Magic."
If Roger remembered correctly, the Department of Mysteries had a "Brain Room," which was likely responsible for this research.
Beyond that, the book had two peculiar aspects.
First, instead of a single cohesive work, it felt more like a compilation of various internal research publications.
Second, large portions of the text were blacked out.
This wasn't something McGonagall did—it was printed this way.
Likely due to the secrecy policies within the Department of Mysteries.
Even so, the remaining content was still valuable.
Initially, Roger had been interested in the book's exploration of whether a wizard's mental power could influence the real world without relying on magic. This theory on psychic abilities was intriguing.
But now, he discovered that it contained even more significant knowledge.
For instance, the authors had absorbed a considerable amount of Muggle medical knowledge and had begun to explore the functions of different brain regions.
When it came to medicine, wizard healers were far superior to Muggle doctors. The additional effects of magical potions alone were things Muggle medical science had been chasing for ages.
So, the progress these wizards made was quite impressive. While they hadn't unraveled all the mysteries of the brain, their depth of knowledge had surpassed Muggle neuroscience by at least a full era.
If he combined the brain-related knowledge from The Connection Between Soul and Brain with the Bloodline Magic and Transfiguration: Speculations on the Future Era, written by an old wizard who extended his lifespan using Partial Human Transfiguration—particularly the "Brain Transfiguration Theory" he envisioned in his later years…
And then integrated it with his own Magical Neuron Technology…
"This experiment is extremely dangerous… Even the slightest mistake could be fatal," Roger muttered.
If something went wrong with a limb or an organ, St. Mungo's might still be able to save him.
But the brain? A single error, and there wouldn't even be a chance for rescue!
Roger had been at Hogwarts for some time now. During this period, he had not only found his path but had also started putting it into practice, steadily growing.
Through this, he had also gained a rough understanding of where his abilities stood in the magical world.
A person's abilities were like a character's attribute panel in a game—everyone had strengths and weaknesses.
Roger's strength lay in his logical thinking and solid worldview, allowing him to absorb, break down, and integrate the knowledge of others into his own system.
His psychic power was exceptionally strong—far surpassing nearly all young wizards and even exceeding some professors who taught weaker subjects. However, due to his lack of skill in spellcasting, his combat ability had yet to match the strength of his psychic power.
With his established theoretical foundation, Roger had developed a considerable talent for magical research. He estimated that his research abilities were at least on par with Snape during his Half-Blood Prince days—placing him in the upper ranks of the wizarding world. But he wasn't some once-in-a-century prodigy.
His rapid progress in magical research was purely because his Seer ability—his sense of crisis—was incredibly useful in this field.
As for spellcasting, he had high aptitude for conceptual-based magic like Transfiguration. However, he was only average at emotion-based magic like Dark Arts and Defense Against the Dark Arts. And he had poor affinity with imaginative spells like Fiendfyre and certain curses.
His greatest weakness was memory.
When studying in the library with Hermione Granger—though they never interacted—Roger noticed that Hermione could memorize entire books after reading them once. Meanwhile, he had to fill his notes with densely packed annotations, recording every fleeting thought in order to retain information.
In terms of thinking speed, he had no real advantage over other wizards. His ability to learn quickly came from having a structured learning method and refined control over his psychic power, not because his brain processed information faster.
Overall, without his Seer ability, Roger had the potential to reach the level of Voldemort. However, breaking past that into an even higher tier would be difficult—only fate could decide.
And even if Roger reached a level stronger than Voldemort, or even several levels above him, the path to immortality was still…
At this thought, Roger overcame his hesitation.
A person who fears death in great endeavors but risks their life for petty gains—such a person does not deserve the fruit of immortality!
So what if the experiment was dangerous?
Which strong individual hasn't endured countless life-or-death struggles?
Hesitation wouldn't make him stronger.
To achieve extraordinary results, he had to undertake extraordinary feats!
Let's do this.
"I need to learn the Undetectable Extension Charm… Wasn't that spell restricted by the Ministry of Magic?"
Having made up his mind, Roger immediately took action.
In his previous life, he had watched a series called A Certain Magical Index.
In that world, a person's combat power was determined by their brain's computational ability.
When modifying Harry to enhance his talents, Roger had wondered if something similar could be applied to himself—to upgrade his potential. Then, he suddenly recalled this concept.
In A Certain Magical Index, some people increased their power by linking their thoughts with others to achieve a unified consciousness.
Others used enormous external brains, the size of houses, to enhance their computational abilities. Roger had no idea how they managed that or how such technology worked.
But with his Magical Neuron Technology, he might not be able to use external brains or link with others—
But he could enhance himself!
For example, if he placed an Undetectable Extension Charm inside his skull and then expanded his brain…
He could achieve absolute memory, parallel processing, thought acceleration by dozens of times—and perhaps, as his brain evolved, even his psychic power would grow stronger.
Of course.
Though Roger had resolved to take on any experiment, no matter how dangerous, as long as the benefits were worth it…
That didn't mean he would blindly rush in.
Roger wasn't arrogant enough to think he understood magic better than anyone else.
Besides, some of his ideas required communication with the Ministry of Magic.
So…
"Professor McGonagall, help me!"
Roger knocked on Deputy Headmistress McGonagall's office door once more.
When in doubt, find someone reliable!
"Hm?"
McGonagall, who had been pondering a rather troublesome issue, looked up in confusion.
