Hogwarts: Wizards of Eternity

McGonagall becoming headmaster might have been accidental.

However, the power of Transfiguration is undeniable.

In Roger's view, Transfiguration is the magic closest to 'God'!

It can turn metal into cotton, toxins into nutrients, water and fire into a gentle breeze, and even the 'summoning and vanishing' spells within Transfiguration can directly change the existence of matter. With just this one spell, all non-magical means in the current world are almost rendered meaningless.

It's no exaggeration to call it the 'ultimate manipulation of matter'!

Even the five principal exceptions to Gamp's Law of Elemental Transfiguration, such as 'food conjured by Transfiguration cannot nourish,' are essentially because the 'integration' after Transfiguration cannot be disassembled before the spell is lifted, preventing the nutritional substances from being broken down into nutrients for the body to absorb.

If a wizard were to transfigure matter from the basic particles, one by one, and then reassemble them into bread, it would still be nourishing... It is the wizard's weakness that limits the potential of Transfiguration, not a problem with Transfiguration itself.

If there were a wizard with a mind power close to a god, powerful enough to understand everything about magic, then he could simulate almost all magical effects relying solely on Transfiguration!

It has the qualification to become the fulcrum to leverage everything.

Moreover, Roger received a systematic scientific education in his previous life, and he is not a very emotional person. Compared to those things that emphasize extreme emotions and spirituality, using 'imagination' to cast spells, Transfiguration, which is closer to rationality and more suitable for using 'conception' to cast spells, is more suitable for him.

Among the pile of theoretical books that Professor McGonagall lent to Roger, besides 'Ritual Magic is Far More Than Blood Sacrifice,' there was another book that Roger found quite interesting.

It was this book that made Roger feel that if it wasn't necessary, it would be best to stay away from Dark Magic. At the same time, he feared that Transfiguration was the most suitable magic for his path to longevity.

'Is Extreme Emotional Spellcasting a Wrong Path?'

This book was written in ancient Europe, in an era when bloody and terrifying ancient magic was very popular. The author was an old wizard with not much time left.

In the era when the author wrote the book, the 'Transformation School,' 'Ritual School,' and 'External Object School' had not yet undergone numerous verifications and become the three major recognized schools of learning, developing into the bloodline soul transformation, Transfiguration, complex ritual magic, alchemy, and potion systems known to the world today.

At that time, in the region where the author was located, another school of thought was popular among the wizarding community seeking power.

The Emotion School!

As everyone knows, emotions account for a significant portion of the power of the mind. Extreme love, hatred, sadness, and joy, the desire to protect others, can often make people explode with unimaginable power!

Just like the magic of love that Lily Potter cast on her son, even Voldemort's Avada Kedavra could not break through its defense.

Even after ten years, Voldemort would still suffer a great backlash from touching it slightly.

And extreme pain creates terrifying creatures like Dementors of Azkaban.

Self-loathing and repression will breed powerful Obscurials.

Different emotions can cause a wide variety of phenomena that transcend the power of ordinary wizards.

Ancient wizards at that time believed that playing with emotions was the correct path to breaking through the shackles of the upper limit of mental power and allowing wizards to become gods.

However, the secluded living environment of wizards today, and the reality that ancient magic has been replaced by modern magic, silently tell the fate of these people.

'Is Extreme Emotional Spellcasting a Wrong Path?' is mostly a reflection of an old wizard on his life, a bit like a personal biography and memoir.

What Roger found most valuable was the two theoretical conjectures that the old wizard mentioned in the book.

'Magic Thought Echo Theory' and 'Magic Choice Theory'.

When the old wizard mentioned this theory, he started from the 'wand,' which is the 'starting point' for almost all wizards.

"When I bought my first wand in my life, Mr. Ollivander told me that the wizard chooses the wand, and the wand also chooses the wizard."

"Don't look at those legendary, transcendent wands. You are not compatible with it. Even if you hold it, you will not become the legendary big shot. You will only be rejected by the wand, unable to cast a single spell, and even suffer backlash."

"This is your wand. It looks unremarkable, but it will grow with you. Every choice you make will change yourself and it."

"The greatness of man stems from every choice he makes."

— Man and wand choose each other and influence each other, and spellcasting is the same.

"Wizards choose magic, and magic also chooses wizards!"

Just like people without happy memories cannot cast the Patronus Charm, and people without murderous intent cannot cast Avada Kedavra.

"Wizards influence magic."

People who are more repulsed by the outside world will have stronger banishing charms, and people who love unrestrained freedom will be better at levitation charms.

"Magic also influences wizards."

People who spend years studying dark magic that requires extreme negative emotions to cast successfully will become more gloomy, full of malice towards many things around them, and easily angered...

"Not only dark magic, but this emotional influence exists in all spells!"

For example, the Shield Charm makes people tend to be conservative, and the Patronus Charm makes people tend to be optimistic... But this is irrelevant, because the influence must also follow basic laws.

The more will and emotion you pour into the spell, the greater the influence the spell has on you in return.

If the will and emotion you pour in are small, then the influence you receive will be minimal.

In other words, as long as you avoid extreme will and emotional spellcasting, and don't desperately push yourself to the limit every time, with your blood pressure soaring and veins bulging all over your body, it's not a big deal.

How many times in their lives do ordinary wizards have to cast spells that risk their lives? A little influence is enough to smooth out over time.

You have to play with dark magic that you can't cast without extreme emotions? Then there's no saving you.

... The above not only made Roger more wary of dark magic and exploitative spellcasting, but also made Roger understand how important it is to choose a spell that suits him.

Just like Harry Potter using Expelliarmus from beginning to end, is it because he doesn't know other combat spells?

Wizards choose spells, and spells also choose wizards. A suitable spell can exert 10 times the effect with 1 power!

Roger wants to achieve eternal life, and the path he has currently chosen is the 'Transformation School' proposed by ancient wizards.

Wizards cannot follow this path because they do not have enough experimental subjects.

And he intends to use his 'Experimental Holy Body,' which can sense danger, to violently decipher the mysteries of life.

Roger doesn't know how long it will take him to achieve his goal.

Maybe a few years, maybe decades, or maybe he won't be able to complete it until the moment of death, like Kuafu chasing the sun, Don Quixote charging at windmills, leaving a little sighing legend to the world after death.

But since he has decided to take the path of longevity, Roger will definitely not give up any choice that can increase his chances of success!

After Roger's testing, Transfiguration not only has high potential, but his compatibility with it is also quite good.

Naturally, Roger will not 'take it for granted' and shut himself off from the world when it comes to matters concerning his life and destiny.

"Professor McGonagall, what do you think of my idea?" After the Transfiguration class ended, the other Gryffindor students left the classroom one after another, while Roger stayed behind. He wanted to seek advice from this knowledgeable professor who had given him much help before.
