During his research into magic, Roger initially absorbed the wisdom of his predecessors. However, after reaching a certain level, Roger found that there was no longer a path ahead.
Humans cannot imagine things beyond their scope of understanding.
Roger's current magical path heavily borrows ideas from various entertainment works and ancient cultivation methods from his past life.
He meticulously experimented to see which of these potentially useful ideas were actually feasible and which were impossible, even with magic.
For instance, when establishing the path for Second Magic, Roger even considered whether he could replicate a version of Hai Hu's "Magnetic Field Rotation" in this world.
After all, he felt that some people in this world were quite eccentric and might be a good fit.
Moreover, this kind of power wasn't weak and had commonality.
But later, Roger discovered it seemed unworkable.
Thus, he abandoned that idea.
Afterward, through step-by-step adjustments and attempts, it transformed into the Illusory True Realm, based on the Dantian Purple Mansion Method and the Demon God phases from A Certain Magical Index.
This time, Harry's problem served as a reminder for Roger.
From the very beginning, Roger set his goals extremely high, so he never considered sacrificing potential for power.
But while he didn't need such a method, many others might.
There are always those who, in their most powerless years, meet the people they most want to protect and have the dreams they most want to realize.
And once Second Magic and the Three-Dimensional Law are laid out, a portion of the power they gain through such methods would be their own.
Since Wizards don't have many opportunities for trial and error, and their methods of sacrificing for power are too inefficient, he could completely use his precognition to create a highly effective version for everyone to use.
As for the specific method...
Roger recalled a work he had seen in his previous life.
Among the extraordinary systems Roger knew of, there were also some that leaned towards idealism.
One of them was particularly interesting.
The Nen ability system from "Hunter x Hunter"!
The content of the Nen ability system is extremely complex; explaining all the different types would take tens of thousands of words.
Simply put, it's a system that uses life energy as a mirror, taking a part of one's spiritual traits as a seed, reflecting it into reality, and then cultivating various interesting abilities.
And among the cultivation methods, there was something Roger thought might be useful.
Constraint and Vow.
In essence, this is a method of exchanging the possibility of constraint and weakening for the ability to become stronger.
For example, if your ability is to create a sword, and this sword is very ordinary.
But if you add a constraint like, "This sword can only cut red things," scattered power will be concentrated, and the sword will become extremely sharp when cutting red objects.
Roger suddenly wondered if similar magic could be applied to magical development.
Like Harry wanting to develop a Time Loop magic.
But what if a 'constraint' was added?
For instance, could this magic only be used on the day Voldemort killed his parents, in exchange for greater power, to push this magic to its extreme?
It wouldn't be limited to this; things like a one-time-use teleportation or three life-saving hairs might also be achievable through it.
"What do you think of this method?" Roger asked Harry after roughly explaining his idea.
Of course, Roger wasn't asking Harry about the feasibility of this method.
When it comes to magic, the old saying holds true: practice is the sole criterion for testing truth. A hundred discussions are not as good as waving a wand once.
Harry had no practical experience in this area, so asking him about it was pointless.
What Roger was asking was whether Harry would be willing to accept it if he actually developed this method.
"I think it's great," Harry's eyes lit up.
His current strength was far greater than it should have been at this point in his original destiny, but he was still the same as in his original fate – he didn't pursue power itself very much.
For Harry, power was merely a tool to achieve his goals, never the goal itself.
What Harry had always yearned for was something he had lacked since his early childhood.
Happiness and love.
If he could ultimately obtain them, Harry would be completely willing to accept losing some possibilities for it.
"Alright, I'll take care of this."
"My time is a bit tight this semester, but I'll make time to experiment with the feasibility of this idea. During this period..."
Before Roger could finish, Harry nodded eagerly, "I understand."
Seeing this, Roger showed a satisfied smile.
Because Roger also had goals he would do anything to achieve, he understood Harry's mindset very well.
To save his parents, he would definitely use every method he could think of to increase his chances of success. If Roger insisted on dissuading him, it would be futile.
But since Harry was crucial to his own path to immortality, Roger didn't want anything to happen to him.
That's why he needed to talk to Harry about these things.
Roger's goal was to stabilize him, give him a target, and prevent Harry from messing around on his own.
After their late-night talk with Harry concluded, Roger, who was conducting experiments, couldn't help but ponder whether this new line of thought, which began with Constraint and Vow, could be applied to his own Path of Immortality.
After much deliberation, Roger shook his head and sighed softly, "Things of the mind are too difficult."
If it were just about magic alone, it would be manageable.
But on the path of the mind, using constraints would only limit his own development and leave a significant flaw in his psyche.
At times, Roger also doubted whether he had made some mistakes in the order of his path.
It was just like the error he made regarding 'power' back then.
Eternal Life, Agelessness, Immortality, Indestructibility...
Perhaps the order should have been Eternal Life, Immortality, Indestructibility, Agelessness? But after considering it, Roger dismissed his doubts.
The sooner one embarks on the Path to Immortality, the better. The older one gets, the more they possess, and the more difficult it becomes to let go of things. This line of thought was not wrong.
"Roger?" Nicolas Flamel looked over.
He could sense an unusual magic power fluctuation emanating from Roger.
While ordinary people might not notice this feeling, it was quite conspicuous to his keen senses.
"...It's nothing, I was just a bit distracted." Roger stopped waving his wand and rubbed his forehead.
This might seem like a minor issue, but Nicolas Flamel took it very seriously. "It seems there are still many shortcomings with multitasking thought. This Second Brain still needs adjustment."
According to Nicolas Flamel's theory, once thought threads are separated, they should not interfere with each other.
In fact, with skilled application, one could cast several different spells simultaneously.
But judging by Roger's current situation, there was clearly magical interference!
