Time ticked by.
One dark night, Lupin carried his luggage downstairs and completely settled in there.
The downstairs had the same six-room layout as the upstairs, except the wall of a secondary bedroom was torn down to expand the hall for everyone to use as a dining room, Lupin chose a small room and set up the most luxurious top-of-the-line home theater of 1991.
This man was a big boss now, incredibly rich.
By the way, ever since Ilsa became infatuated with a piano prince character in a TV drama, a jealous Lupin bought an ultra-expensive piano and hired the most expensive private piano tutor.
The only problem was that the private tutor was too elegant and beautiful, and now it was Miss Ilsa's turn to be jealous.
While it was all lovey-dovey downstairs, it was a tragedy upstairs.
Pedro's wails had gone from loud and clear at the beginning to barely breathing now.
He felt like he was dying.
He finally understood how Rosier had forced him to take him into time, traveling tens of thousands of times over fifty years.
He was tied to a rune-covered chair with terrifying, arm-thick dragon tendons, so he couldn't Apparate to escape.
And because the 'Goblin's Eye' secret art required entering the depths of memory through the eyes, the windows to the soul, Rosier pried his eyelids wide open.
"I'm your good friend, Rosier, let me go, I'll die if this keeps up!"
Rosier just sneered, "Nagini is your daughter, and Anna is your granddaughter, you should have some self-awareness."
Anton didn't care what they were saying, he just kept drinking potions, exploring memories, and writing notes.
Anna helped organize the materials on the side, countless stacks of parchment had already filled Anton's study, and now they could only be placed in Lupin's original room.
Sometimes Anton would suddenly pull out a draft paper, rush to the room to search for something, and spend the whole afternoon in thought.
And this would be Pedro's most comfortable moment.
Although Rosier was watching him closely at all times.
"I have my own things to do too, Rosier, don't be fooled by how naturally Lupin is living now, if he casts spells multiple times, the previous problem will reappear, and I'm still bound by the 'Unbreakable Vow' curse, I'll die if I don't heal him," Pedro had to beg in a low voice.
"There will be plenty of time later!" Rosier flatly refused, "Don't you dare make any mistakes for me!"
"We should indeed heal Lupin first!" Anton walked out, his eyes lit up, and he excitedly patted Pedro's shoulder, "Great, you reminded me."
"Hahaha, by using the Dislocation Hex and the Soul-Shifting Charm, I can manually change the shape of a soul, what a perfect solution," Anton excitedly ran back to his room with the parchment.
Rosier and Pedro looked at each other, "What did he say?"
"I don't understand either."
"You've lived for hundreds of years and you don't understand?" Rosier looked at him with contempt.
Pedro didn't retort, just looked at Anton's back with a complicated expression, "You don't know, Rosier, he had so many opportunities to learn more goblin secret arts and potions from my memories, but he didn't, he just focused on completing the 'Bionic Charm' with Volkanova's theory."
"He's researching a magic that might be completely useless to himself, and he's delved into it extremely deeply."
"Rosier, we both owe him a favor."
Rosier didn't see it that way, "He saved Nagini, so I already owed him a favor. But with this research, whether he becomes a werewolf or a viper, it's extremely powerful."
Pedro chuckled, "If he put the same effort into the Shield Charm, the magical resistance he'd gain would be far better than turning into a werewolf. He's right about himself, he barely knows any proper spells, those are what he should be studying the most."
Rosier was silent for a moment, then made a decision.
"I'll have Durmstrang Institute send him an acceptance letter, I'm on the board of governors, Headmaster Karkaroff will do me this favor."
There are three major magical schools in Europe, each with its own characteristics.
Of course, with Dumbledore, Hogwarts was currently the most dazzling.
But among the old pure-blood families, the first choice was always Durmstrang Institute, this school only accepted students from pure-blood families, and the knowledge they taught was not for the purpose of entering the Ministry of Magic, but for developing the family's future.
More powerful, more dangerous, and also more inclined towards the Dark Arts.
Rosier felt that Durmstrang Institute was practically made for Anton.
Counting the time, the major magical schools should be sending out acceptance letters to new students.
"Anna, go inform Lupin to prepare for Pedro's treatment, and by the way, tell him I'll be conducting a small experiment on him, it won't kill him," Anton walked out in a hurry.
"Pedro, go prepare for the experiment, when the time comes, I'll use the Dislocation Hex to distort his soul, you remember to extract all the Cruciatus Curse magic, make sure to clean it up completely, there can't be the slightest mistake."
Anton slapped a piece of parchment into Pedro's arms, "We'll do this along the way, let's give it a try, if it works, Nagini can be saved."
After speaking, he hurried back to Lupin's room to look for other materials.
Anna stood behind him with a worried look, "Father, he hasn't slept for a week."
Rosier, however, chuckled, "I like this kid."
"???"
Everyone got busy, Pedro set up a large amount of machinery in the hall, the ones that had been destroyed by Snape before, he had been repairing them all this time, otherwise he would have completely cured Lupin long ago.
Lupin and Ilsa came back from work, Ilsa seemed a little at a loss, Lupin could only comfort her, "Anton would never harm me."
"The principle is very simple," Anton was finally ready, looking around at everyone.
"According to the witch Volkanova's view, all things originate from a certain primitive point, so what we are doing is flipping an object to its other side, and this side is influenced by our memories, will, soul, and even everyone related to us."
"Werewolves and humans, vipers and humans, are just different sides!"
"And the appearance of this side is influenced by the wizard's will."
Anton tried to use the simplest words so that everyone could understand, "For example, the Patronus Charm, according to this theory, its essence is the external manifestation of the desperate desire for protection within our souls, expressed through magic."
"So!" Anton raised a finger, "why do we involuntarily turn into werewolves or vipers?"
"I have plenty of transformation experience, and I have all the magical images of a werewolf transformation observed by my teacher and me."
"I found that a corner of our soul is controlled by an invisible will, it can be the wolfsbane poison, it can be a curse, it can be the will of a wizard who cast a transfiguration spell."
"It's like a switch that, when certain conditions are met, flips us to the other side!"
"Of course, we can't cut out our will like we're performing surgery to remove an unwanted organ."
"Nor do we have enough emotion to influence this will that carries magic."
"But we can deceive it!"
"Targeting this will, give it an incorrect command to turn off and on."
"Simply put, Lupin, you can make the wolfsbane poison in your body think that today is the full moon night, and you will turn into a werewolf, similarly, on the night of the full moon, the wolfsbane poison in your body will think that the full moon has already passed, and will no longer turn you into a werewolf."
Lupin's eyes widened, "You mean I can freely control when I turn into a werewolf?"
Anton nodded with a smile, "For now, this is all we can do, freely choose the time within each month."
"I will continue to research in the future, to find a way to make your will directly forget about the full moon night, so that no matter if you have wolfsbane poison in you or not, you won't turn into a werewolf."
Lupin's breathing became extremely heavy, "Anton... thank you."
Ilsa held his hand tightly, her eyes full of hope.
"Then let's begin, Pedro, prepare for the surgery, after the incision, I will use the Light and Shadow Charm to mark the area that needs to be influenced, you make an opening there."
Pedro swallowed, exclaiming in amazement, "You're a real madman!"
Anton smiled smugly, "Rosier, you get ready, we'll do it all in one go, and do the same for Nagini later, I think this kind of surgery will definitely delay her transformation into a snake by at least ten years. Ten years is enough for me to find a complete cure for Nagini and Anna."
