Returning to Hogwarts, Aiden and Dumbledore replicated their previous operation, carefully removing the dark 'filth' from the Resurrection Stone.
"Professor, you must promise me first: no suicide!" Aiden said, clutching the ring in his hand and looking seriously at Dumbledore.
"Alright, I promise you," Dumbledore nodded solemnly.
Getting Dumbledore's guarantee, Aiden casually tossed the ring, and Dumbledore reached out with both hands to catch it carefully.
"Be careful! What if it breaks?" Dumbledore said, very gently putting the precious ring away.
"Heh," Aiden said, rolling his eyes and walking out of the headmaster's office.
Ignoring the Headmaster who was obsessed with playing with ancient stone, Aiden decided to find Professor McGonagall.
Knocking on her door, Professor McGonagall was holding a book, enjoying her rare holiday time.
"Sorry to disturb you, Professor," Aiden said, handing over the complete thesis.
Professor McGonagall took the thick parchment and began reading with obvious interest.
Her brow sometimes furrowed, sometimes relaxed, and when she read key parts, she would show a look of sudden understanding.
Soon, Professor McGonagall finished the comprehensive thesis, organized it neatly, and set it aside.
"Mr. Prewett, have you given it a name?" Professor McGonagall asked with obvious excitement.
"Uh, not yet..." Seeing Professor McGonagall's excited expression, Aiden knew exactly what she wanted to do.
"Then how about thinking of one on the spot?" Professor McGonagall said, having already handed over paper and pen.
"Uh, Super Transform Transform Transform?" For some unknown reason, this ridiculous name suddenly flashed in Aiden's mind.
Sure enough, Professor McGonagall's face immediately elongated with disapproval, and she reached out to ruffle Aiden's hair. "Change that!"
"Give me some reference suggestions," Aiden pleaded desperately.
Professor McGonagall withdrew her hand, noting that his hair texture was quite nice... getting off topic.
She thought for a while and said, "Since it involves the conversion of objects' essence, how about including 'qualitative transformation' in the name?"
"Qualitative Transformation Technique?" Aiden said, stroking his chin thoughtfully.
"Qualitative Transformation Technique."
Professor McGonagall shook her head and helped him complete the proper name.
"That's good, let's decide on that," Aiden immediately made the decision.
"I must remind you, Mr. Prewett, this kind of magic is not something ordinary wizards can handle, so it probably won't appear in Hogwarts' curriculum."
Professor McGonagall waved her wand, and an envelope flew out to absorb the thesis.
Then an owl flew in through the window, picked up the envelope, and flew out into the winter sky.
"It's fine. My original intention wasn't for the students in school anyway. After all, researching these things costs too much, and students can't afford it," Aiden said with a casual shrug.
"Then I look forward to your masterpiece," Professor McGonagall said, taking a sip of tea.
"What masterpiece?" Aiden asked, tilting his head in confusion.
"'Prewett's Book of Transfiguration,'" Professor McGonagall said, narrowing her eyes with anticipation.
Aiden stared in horror. "..."
Carrying a new unwanted task, after saying goodbye to Professor McGonagall, Aiden very much regretted why he had asked that extra question.
But since things had come to this point, and organizing and publishing his research results was indeed a very glorious thing, Aiden still reluctantly accepted the task of writing a book.
Friday, Aiden came alone to the Room of Requirement, preparing to explore a gatekeeper before the Unforgivable Curses.
That was the notorious Fiendfyre Curse.
According to the dangerous book 'Most Potent Magical Poisons,' the essence of the Fiendfyre Curse wasn't for the caster to directly create flames.
Rather, it was a form of disguised summoning, making destructive flames descend upon the mortal world.
"Fiendfyre!" A ghostly blue flame flew from Aiden's wand tip with menacing beauty.
The strange will contained in the flames emanated dark power, and Aiden immediately used Finite Incantatem to extinguish them.
Flames containing mental power! Aiden immediately recognized what that disturbing fluctuation was.
"But this familiar rhythm and fluctuation... I feel like I've encountered it somewhere before?"
The Manipulator's excellent control over himself made Aiden instantly recall the source of this déjà vu.
"Kingport! Deep Realm King of Hell?" Aiden exclaimed with sudden realization.
"Yes, you found the key point, young student," the system came out to offer cryptic commentary.
"System? Do you know something?" Aiden inquired with growing interest.
"In all the years the Deep Realm Kings have existed, there couldn't possibly have been no one who researched them," the system hinted meaningfully.
"Even a weak, pitiful, and helpless system like me can help you separate Dream Weaver extraordinary characteristics from Resentment. There's no reason that wizards who can directly rewrite reality haven't produced such genius figures. What's a mere Hell? Besides, using Deep Realm Kings' bodies... aren't you and the Department of Mysteries already doing this?"
The system spoke of these shocking secrets in a deliberately flat tone.
"That's true... wait, you currently have a Dream Weaver characteristic?" Aiden asked, catching the key point in the system's words.
"Yes, I originally wanted to wait until you finished digesting the potion before telling you," the system replied casually.
"What else do you know? Tell me what you can say," Aiden wondered if he could extract more valuable information from the system.
"Not much more. Besides Hell's matter, there are those Eastern practitioners. The cave heaven I showed you before is actually built on a giant tree. From what I accidentally... heard, their so-called Jianmu should be the Deep Realm King called Life."
The system continued dropping shocking revelations, and Aiden simply took out lemon juice to drink while absorbing this incredible information.
"Amazing, they truly are," Aiden couldn't help but applaud in genuine praise.
Nothing else, the system is running low on information, the system acted cute and went into lurking mode.
Aiden thought on the spot. Forget it, too lazy to think deeply. Let's continue practicing Fiendfyre.
Raising his wand, he summoned Fiendfyre again. Under the Manipulator's powerful mental control, Fiendfyre was successfully controlled by Aiden.
The ghostly blue flames became phoenixes in the air one moment, dragons the next.
Having played enough, Aiden used Finite Incantatem to extinguish the Fiendfyre, the whole process like a child playing with matches before throwing them into water.
Just as Aiden was about to leave, an intriguing idea came to mind.
"Since Fiendfyre is a manifestation of the Deep Realm King, can I utilize its inextinguishable characteristics?"
Once the thought arose in Aiden's mind, it became absolutely uncontrollable. Aiden summoned Fiendfyre again while using mental power to contact it directly.
Then Aiden felt the violent emotions within the flames. Stripping away the high-concentration emotional power within, the flames extinguished naturally.
"That's right. The essence of Deep Realm Kings is just aggregations of high-concentration emotions. As someone with an extremely high, extraordinary position, I should be able to do this too."
Aiden used Animagus to transform into his dragon form. After a period of careful mental suggestion, he released his mythical creature form.
In the Room of Requirement's testing ground, Aiden shifted into his mythical creature form and opened his mouth, drawing upon the intense anger and violence he had absorbed from Fiendfyre.
Aiden tried to breathe dragon breath. Mental breath penetrated the dummy but didn't cause any visible physical damage.
But it didn't produce Fiendfyre's inextinguishable and proliferating abilities.
"Missing something," Aiden said, scratching his chin with his claw.
Ignite your distracting thoughts and infuse them into the mental breath, the system suddenly reminded Aiden.
"Hmm!" Aiden's eyes lit up with understanding.
Breathing dragon breath at the dummy before him, this time Aiden breathed the same invisible mental breath.
But the breath seemed to carry something fundamentally different. The dummy was ignited and completely turned to ash in less than a second.
"Success," Aiden said, transforming back to his original form, nodding with satisfaction, packing up his things, and returning to Ravenclaw Tower.
