Since Ian received all the memories of Grindelwald, he sealed himself in the research room for three full days.
Those memories flooded into his mind - his entire life from 1926 to the present, as well as the duel that shocked History of Magic, were analyzed frame by frame by him.
The battle between Grindelwald and Dumbledore can indeed be called a "legend".
Even with Elder Wand in hand, Grindelwald still loses.
Ian knows that it is not just because of lack of strength.
Grindelwald had foreseen his own ending before the war.
He once saw the future during meditation - he was imprisoned in the prison tower of Nurmengard, talking to a vague figure.
The man had no face or voice, only a pair of deep eyes.
He knew that he would entrust that person with everything - including his memory, knowledge, and his and Dumbledore's blood.
"Who is that person?" Grindelwald asked himself repeatedly in his memory.
It was not until many years later, when Ian actually appeared in front of him, that he realized that fate had already written the answer into the gap in time.
He once fought hard against Dumbledore, not only for his ideal, but also to verify "Prophecy".
He wanted to see clearly when that future would come.
So, in that duel that was doomed to fail, he tried his best to collect a drop of blood from Dumbledore--
That drop of blood was later sealed and preserved by him, and eventually became the research material of Ian today.
After reading these memories, Ian let out a long breath.
"So that's it," he murmured, "He has already seen me."
He finally understood the calmness and calmness of Grindelwald back then - it was not arrogance, but resignation.
"Prophecy has no effect on me," Ian thought to himself, "The future he saw was not destiny, but a cycle he actively promoted."
He closed his eyes and his thoughts gradually cooled down.
The magic research left behind by Grindelwald is extremely complex, especially in the fields of soul, bloodline and consciousness, which is shocking to the world.
If these achievements can be fully absorbed, his "world plan" will have no obstacles.
But before that, there is a more difficult problem:
Dismissal of Second Limitation.
--
There is still one month left before Hogwarts starts school.
Ian still retains the position of professor.
He knew that becoming a teacher was the best way to penetrate the minds of young wizards Britain--
Influencing the future is more efficient than controlling the present.
So, he taught classes in the castle during the day and immersed himself in experiments at night.
The ancient magic circle shines with blue-white light,
He used the ritual language in Grindelwald's memory to reshape the runes,
Gradually explore the structure that "limits" existence.

At the same time, Hogwarts is in another place - Headmaster's Office.
Dumbledore was sitting behind the desk, flipping through one newspaper after another.
The wooden bookshelves in the office are filled with newspapers and periodicals--
<Magical Daily>, <Wizarding Gazette>, <European Magical Forum Bulletin>... and even <Wand Monthly> from the mysterious country in the East.
Professor McGonagall pushed the door open and handed a document to him.
"Albus? You have been restless recently." She frowned and asked, "Since Ian's speech, you have hardly slept a wink."
Dumbledore raised his head and still looked away from the newspaper.
"That's true, Minerva." He said softly, "I always feel that something is wrong."
"What's wrong?"
He pushed several newspapers in front of her.
"Look at these headlines."
McGonagall randomly picked out a few pictures and read in a low voice:
"'Professor Flitwick became the third wizard to survive Avada Kedavra',
'Potions Master successfully resisted Avada Kedavra--Bones family alchemical products detonated the world',
'Bones family: Wizarding World's new future?'"
She turned over a page and even saw the title of the Chinese newspaper--
"'Britain Bones family launches the universal Talisman, breaking through the traditional wizard barriers'."
She raised her head and said doubtfully, "These reports almost all revolve around Ian and Bones family.
Is there something wrong? Isn't this just family propaganda?"
Dumbledore sighed, "If it were anyone else, I would think so too.
But Ian... he never acts without a reason.
There must be a purpose behind everything he does."
"You mean--"
"I'm worried," Dumbledore said in a heavy tone, "He has already started his plan."
McGonagall was startled.
"But didn't he deny it face to face? You asked him personally in that interview."
"Yes." Dumbledore smiled bitterly, "But you and I both know that he never lies.
If he says 'I haven't started yet' then, that means - it's just a matter of time."
He got up and walked to the window, overlooking the mountains in the distance.
"An old friend told me that he saw Ian in 1926."
"1926?" McGonagall frowned, "Isn't that more than sixty years ago?
Is he studying Time Magic?"
"That's right." Dumbledore whispered, "And, Nicolas Flamel confirmed,
Ian has been successfully refined into Philosopher's Stone--and obtained immortality through it.
Coupled with his homemade Youth Potion, he may have... got rid of time."
There was a long silence in the room.
McGonagall's voice was almost as low as possible. "Then what are you going to do?"
"I don't know." Dumbledore stared at the starry sky outside the window,
"I half expected to see the new world he built,
The other half is afraid that one day he will be swallowed up by knowledge.
What he pursues is not power - but Truth who understands everything."
McGonagall also fell silent.
She had discussed Transfiguration with Ian in depth.
That day, he told her:
"The ultimate of Transfiguration is Matter Manipulation - everything from atoms to quantum can be changed by will."
It took her several months to understand it, and from then on, she could no longer look at magic in the same light.
"Maybe..." she whispered, "He can really bring about a new era."
Dumbledore sighed lightly and did not answer.
He slowly sat back in his chair and took out a piece of parchment.
"No matter what, I must deal with the problem at hand first--Cornelius Fudge."
"Minister for Magic?" McGonagall asked in surprise.
"I suspect Ian is paving the way for Bones family, allowing Amelia to run for Minister for Magic.
If that happens, Britain's Wizarding World will completely fall under his control."
McGonagall was slightly shocked. She understood Ian and understood that he was fully capable of doing it.
"Are you going to warn Fudge?"
"Yes," Dumbledore nodded, picked up a pen and wrote a brief letter,
"But I'm afraid... things won't be as simple as they appear."
He dried the ink and handed the letter to a snowy owl.
The wind outside the window blew the white feathers, and a long cry came from the night.
The moment the letter flew out of the top of the Hogwarts tower,
An imperceptible magical rune flickered on the envelope for a moment.
That is the mark left by Ian.
