Awesome, is there really so much?
So the Blood Alliance changes size based on the number of vows? Although somewhat curious to explore it, William ultimately decided to abandon these trivial details, carefully read the terms on the parchment, and then made a few supplementary suggestions—
"…For example, what does it mean by not being able to use your thoughts to influence students? What if he influences a professor?"
"…Alright, but it seems like the Blood Alliance can't be modified?"
"That's simple, just do another one from the start—this time use an Unbreakable Vow, if you accept, I can refrain from deporting or killing you."
At the latter part of the sentence, William looked at Grindelwald, his tone calm. The Unbreakable Vow is very similar to the Blood Alliance, but in essence, entirely different; the most crucial point being that the shattering of a Blood Alliance might only lead to a bit of discomfort for both parties, whereas breaking an Unbreakable Vow…
Only results in death.
Furthermore, only the pledge-maker dies, this charm was actually used by ancient Wizard Nobility to restrain slaves.
And William's proposal made Dumbledore's face tense slightly; he glared at Grindelwald, seemingly wanting to observe his reaction—but Grindelwald's reaction was quite normal, he just nodded expressionlessly, then lowered his gaze to meet Dumbledore's, speaking in a gentle tone, "So, Albus, what do you think?"
Witnessing the interaction between the two, William finally couldn't help but rub his chin, starting to speculate about the "binary relationship" between the two elders.
If it weren't for being unwilling to break up this sunset-colored pair… hissing, not right, pair? He would definitely have no hesitation in deporting or killing Grindelwald to prevent future troubles.
"…If you are willing?"
Dumbledore's tone carried a probing intention, and upon hearing the elderly man's words, Grindelwald suddenly laughed, then he looked up at William, "Alright, I agree with you."
"Then…"
Dumbledore's expression seemed a bit dazed, but he quickly recovered, then stood up to speak, only to see William extend his hand towards Grindelwald ahead of him.
"I want to personally keep an eye on him."
Without turning, William kept his gaze locked on Grindelwald.
And as soon as he finished speaking, not giving Dumbledore a chance to react, Grindelwald smoothly grasped his right hand, turning to look at Dumbledore, his murky silver-gray eyes carrying an inexplicable meaning, "I'm ready, Albus."
Dumbledore's gaze flicked between the two, finally settling on their clasped hands, letting out a deep sigh.
Finally, he pulled out his magic wand, the brown Elder Wand gently tapping on their joined hands, softly muttering, and the next moment, a deep red light shone forth. Seeing the charm successfully take effect, William shook the parchment he had modified, raising an eyebrow—
"So, Grindelwald, in Hogwarts and surrounding regions, you must not use any form of mind imprint to brainwash or influence any intelligent life form, do you agree?"
"I agree."
As Grindelwald's words fell, a deep red chain emerged from the radiant glow in their palms, tightly binding their arms together, the slight burning and stinging sensation made William frown—
Not that the feeling was unbearable, but… the boy's gaze swept over the long strip of parchment in his hand, his eye twitched slightly.
He actually forgot that each sentence of an Unbreakable Vow would add another chain, which means…
Damn, underestimated it…
...
...
Half an hour later, William walked out of the Headmaster's Office, shaking his still slightly numb arm. As expected, every additional sentence resulted in another chain, in the end, the glowing red chains appeared almost as a single entity, and the slight sting had escalated—
"Tsk, should have known not to jump at it…"
Unlike Dumbledore's previous distrust, William never doubted Dumbledore's loyalty to Hogwarts, given his reputation. It's the same old principle, if Phineas Black were sitting in that seat, he would definitely turn around and… directly cast two Killing Curses.
To be honest, if no accidents occurred, his intention at the time was to be a professor for two years, get along for one and then directly take Blake down.
A being so despicable… habitually flogging a certain legendary headmaster in his heart, William sighed—though now the measures on Grindelwald are almost foolproof, provided he pays attention, the other probably won't cause any trouble—
But, it seemed like some intuition was telling him that things might not be so simple.
… Forget it, for now, anyway, he's done the best he can, let future him deal with future problems.
Stretching lazily, and relieving a body sore from all the hustle and bustle, William identified the direction to the Room of Requirement, then… unsurprisingly got lost in the castle for twenty minutes, eventually finding the right path with the help of Mrs. Loris who was patrolling.
...
The following days were busy yet fulfilling for William, searching for records about the Seik Crystal, continuing to study Dream Magic, and promoting it in the Duel Club. The consequence was those not selected regretted ever more, even pleading with Harry to convince William to expand the selection by two people—
So, in the first Dream Club session post-selection, William directly introduced the now nearly complete "Tower-Climbing Roguelike Wizard Battle" game and let everyone in the Duel Club experience it—
To be honest, this approach was unexpected for everyone; they thought William's teaching would be just like before, even if changed to small classes, it would still be attack or defense spell teaching, plus some practical training, those not selected didn't regret much.
But now, because William didn't restrict the Duel Club members' freedom of speech, the next day, the game mentioned by William spread throughout the castle.
Then came endless wails of regret.
Perhaps the little wizards didn't understand the significance of accumulating experience through such practical exercises, nor William's good intentions—but, they knew, this was a realistic game, in an era where red and white consoles had just emerged less than ten years ago, what William produced was essentially a dimensional reduction strike—
Of course, William didn't heed the clamors of these people, after all, sustaining Dream Magic was exhausting, to single-handedly drag everyone in the school into a dream?
No chance.
So, William decided to relax a bit after overworking for a long period, just in time as he had some things to do—
"…How about we just leave the castle?"
In the Room of Requirement, Lupin appeared a bit apprehensive, uneasy as he settled himself into a chair, nervously grabbing at his collar while looking at the increasingly dark sky outside, he spoke to William in an urgency-laden tone.
"What are you worried about, haven't you drank the Magic Potion already?"
William also gazed at the sky outside, and at the edge of his vision, a silver-white light silhouette had already emerged— to ensure nothing went wrong, he had specifically synced the Room of Requirement's weather with the outside, giving Lupin a safe transformation space.
However, he also needed to do some things.
"I know, but…"
Lupin sighed; he certainly knew what William said was correct, his anxiety was over the top; despite numerous transformations during the previous summer holiday without any mishaps, it's not easy overcoming deep-seated habits, fortunately, with the moon rise, Lupin had no time to flee—
"Awwooo—"
Accompanied by a wolf's howl, Lupin's frame began to hunch, fur grew rapidly, muscles multiplied several times, but due to prior experience, the flexible clothing didn't tear as it used to.
And seeing Lupin successfully transform, William nodded, ensuring the other hadn't lost consciousness, he pinched the Mandrake Leaves next to him and placed them in his mouth.
Great, next is the real torment—
Thinking this, William swallowed a gulp of saliva…and then, he realized the leaf in his mouth had disappeared.
