After leaving the classroom, Kyle headed straight back to his dormitory.
He had gathered quite a bit of material over the past two days, so instead of heading to the library, he went back to his room, deciding to take some quiet time alone to sort through everything.
Upon returning to his room, Kyle collapsed onto the sofa.
Pulling out his notebook to organize his thoughts, he drew his wand at the same time.
He tapped the tip of his wand against his temple.
A thread-like strand of misty white vapor floated out and attached itself to the tip of the wand—this was Kyle’s latest understanding of runes, alchemy, and the energy storage chamber.
A large silver dog trotted over.
This was the Patronus Kyle had summoned using the Patronus Charm.
Pale-silver light flickered continuously on the dog’s body, as though transmitting some kind of signal to Kyle.
Meanwhile, Kyle slowly guided the wand toward the dog’s head.
Because the memory he was transferring contained so much information, casting this spell took a noticeable toll on him.
As the misty white memory thread slowly merged into the large silver dog’s head, Kyle let out a sigh of relief.
The dog appeared strikingly vivid and alert, a gleam of intelligence shining in its eyes.
It nodded to Kyle, then picked up the documents on the energy storage chamber from the table with its mouth, dropped them onto the floor, and began reading them with complete concentration.
That was right—a large dog was actually reading magical reference materials.
Or rather, a conjured entity summoned by the Patronus Charm was currently reviewing magical notes!
This was a hybrid spell combining the Patronus Charm and Legilimency.
During his second year, Kyle had first learned about the Patronus Charm in *Detailed Introduction to White Magic*.
According to the book, once a wizard’s research into the Patronus Charm reached a certain depth, they could summon a corporeal Patronus.
At that stage, the Patronus possessed rudimentary thought processes and could help the caster deliver messages.
One only needed to tell it who the recipient was, and the Patronus would seek out the target on its own and carry out simple commands.
Once the spell was dismissed, whatever the Patronus had seen would be fed back to the caster to some extent.
Upon learning this, Kyle had immediately thought of a hit manga from his past life—*Naruto*—and the iconic jutsu within it: the Multi-Shadow Clone Technique.
That technique had a unique mechanic: every clone possessed its own consciousness and could fight, scout, practice jutsu, or even conduct research on its own.
Once the technique was dispelled, all insights and memories would be transferred back to the original body.
The protagonist of that manga had relied on this cheat-like technique to make a name for himself early on.
Kyle had already worked out two uses for the cheat he brought with him when he transmigrated.
The first was assisting him in practicing spells, alchemy, and other technical skills.
The second was aiding research.
As long as the direction was correct, the project’s progress bar would advance.
For every 10% the progress bar moved forward, it would grant Kyle a wealth of insights, sparking even more inspiration.
Both applications required the backing of magical theory.
For the first application, the deeper his understanding of magical theory, the faster his skills leveled up.
The second application required even more theoretical support to push the progress bar forward.
The Patronus Charm had shown Kyle a glimmer of hope for giving himself a massive boost.
Imagine it: sending the Patronus to learn magical theory and conduct research.
After dispelling the spell, all the memories and insights would be fed back into Kyle, advancing his cheat’s magical theory level and pushing the research progress forward.
Then, the cheat would feed back insights, which Kyle could inject back into the Patronus so it could continue its research.
This wasn’t just a 1+1=2 boost in efficiency—it meant the Patronus could enjoy the cheat’s benefits as well.
With two cheat-level entities working together on research, Kyle couldn’t even fathom what kind of results they might achieve.
To upgrade his cheat, Kyle began practicing the Patronus Charm relentlessly to increase his mastery of the spell.
As a result, the Patronus Charm became the very first spell Kyle maxed out.
The effect of reaching max level was that the Patronus could remain active 24/7, possessing formidable spell resistance and devastating power against dark magic.
As for the accompanying spell required for the combo, Kyle’s initial idea had been Transfiguration.
He had wanted to use Transfiguration to grant the Patronus higher intelligence, thereby enhancing the memories and insights it fed back.
But faced with reality, Kyle had no choice but to abandon that route.
His extremely low talent for Transfiguration meant his effective practice ratio was terribly low and highly inefficient.
Afterward, Kyle compared two alternatives: modifying the Patronus Charm itself, or researching memory magic.
In the end, he chose to delve into memory magic and find a way to combine the two spells.
Because Kyle realized that while the Patronus Charm appeared to be merely a white spell involving the manipulation of emotion— where recalling joyful, happy memories and channeling those feelings during casting led to success— and sufficiently joyful memories strengthened the power of the Patronus— in reality, the Patronus Charm touched upon the most fundamental part of a person: their soul.
Successfully casting it actually required using happy emotions to mobilize the power of the soul.
This meant learning the Patronus Charm only required step-by-step practice.
However, trying to modify it called for magical theory far too profound for Kyle’s current level.
And the anomaly that occurred when the spell reached max level proved Kyle’s theory.
The instant the charm hit maximum level, excruciating pain caused Kyle to pass out.
Because at max level, the Patronus Charm had actually torn away a piece of Kyle’s soul!
