He needed an active, controllable, and safe way to "farm experience"—one that would allow him to continuously "produce" ownerless magic that could be absorbed.
"To become ownerless... the first thing it needs to do is break free from the caster's mental control..."
"The essence of a spell is mental power—will—driving magic—energy..."
His gaze unconsciously followed the paths of sunlight cast through the window, watching the dust motes tumble and gather within them.
"Wait... mental power..."
"Not all mental power is directional or an offensive 'will.' Some of it is creative and protective... for example..."
A spell, like lightning tearing through the night sky, instantly illuminated his mind.
One that third-year Hogwarts students would only just come into contact with, yet was one of the most famous and powerful defensive spells in the entire wizarding world.
Expecto Patronum.
This spell was fundamentally different from other spells.
It was not driven by malice, but fueled by the purest and most powerful positive emotions, transforming the wizard's own magic into a corporeal Patronus composed of pure positive energy.
"Joyful emotions... That in itself is a powerful yet gentle form of mental energy."
"A magical construct created with this kind of mental energy should theoretically be 'directed' toward opposing darkness rather than attacking any specific target. Its energy is pure light and protection, the complete opposite of the 'annihilation' of Avada Kedavra."
"If... I can summon my own Patronus, then use my spiritual soul to 'reclaim' the magic that forms it...?"
The moment this thought appeared, it began to grow wildly, impossible to suppress!
This was practically a perfect closed loop!
Generate joyful emotions → use them to cast the Patronus Charm → create a mass of pure, ownerless positive-energy magic → analyze and absorb it with his spiritual soul → convert it into
