Before starting to refine Philosopher's Stone, Ian decided to return to Earth temporarily.
The difference in time flow surprised him - the experiment on the moon only lasted a few days, but a full month had passed on the earth.
He first wrote a letter about the situation through magic communication and sent it to his family, friends and partners to inform him that he was safe and sound.
While sorting the letters, a letter sealed with gold sealing wax caught my attention.
The envelope bears an ancient alchemical seal and a familiar signature in cursive script.
After reading the content, Ian smiled slightly, and then the next morning, he put on a black dress, took out Floo Powder, and stepped into the fireplace.
Green flames rose and his figure disappeared.
--
When the fire went out, he appeared in front of the fireplace of an old French house.
The air is filled with the smell of old wood and herbs, and a fourteenth-century static oil painting - Muggles painting - hangs on the wall, without any magical fluctuations.
He recognized the era and style of these paintings at a glance.
"It really suits this master's taste." He thought to himself.
Soon, slight footsteps came from the corridor inside the house.
An extremely old man walked out slowly.
The body was so thin that it was almost transparent, as if it could be blown away by a gust of wind.
However, those eyes are still bright and steady, like gems that have not been weathered by the years.
Ian stepped forward and gently held his hand.
"Mr. Nicolas Flamel, it is my honor to meet you. I was surprised when I received your letter."
"Oh?" The old man smiled hoarsely, "Didn't you ask Dumbledore to give me the care-of-address?"
"Honestly, I thought he wouldn't do that."
Flamel sat down slowly and said in a calm tone, "That means you don't know him well enough.
His attitude towards you is both appreciative and wary.
On the one hand, he expects you to bring Wizarding World changes;
On the other hand, he is afraid that you will repeat his old ways - like Grindelwald, like Voldemort.
He thought it was the guilt and shadow of his life, and he didn't want to make the same mistake a third time."
Ian was silent for a moment, frowned slightly, and then smiled lightly.
"Maybe I did look at him with prejudice. Forget it, let's not talk about him."
Flamel nodded slightly and motioned for him to sit down.
Then, a slender old woman walked in carrying a tea tray - that was Perenelle·Flamel.
She smiled kindly and placed the tea cup in front of Ian: "Your Youth Potion is really magical. It makes me at least a hundred years younger."
Ian nodded slightly. "I'm very happy that it works."
After the two Alchemy masters chatted for a while, they got to the main topic - knowledge exchange.
"Mr. Flamel," Ian said solemnly, "I have a method that allows us to share knowledge more efficiently.
However, this process may be somewhat painful."
Flamel's eyes flashed with curiosity. "Come on, my old bones are still in pain, aren't they?"
He really had no worries.
From the moment Ian stepped into the room, he realized that this young Alchemy master had broken through "First Limitation".
Being able to achieve this through bloodline transformation shows that his research is far beyond ordinary people.
Even if he activated all the defensive barriers in the room at this moment, he would not be able to do anything to the person in front of him.
Therefore, he chose to trust.
Ian took out a crown set with sapphire from the bottomless bag and put it on his head.
As the soft light circulates, ancient runes appear.
Flamel glanced at it and immediately recognized the legendary Divine Artifact: "That's...Rowena·Ravenclaw's Diadem?"
"Strictly speaking, it's a version I copied after analyzing the original." Ian replied.
The old man sighed, "It's great to be young, even miracles can be used as experimental materials."
Ian smiled and did not answer, he just raised the wand and touched his forehead lightly.
A ray of white light slowly escaped and pointed directly at Flamel's forehead.
It is a linking spell that uses the soul as the intermediary.
Flamel did not hesitate and allowed the light to enter the body.
The next moment, he found himself in a magnificent palace.
The hall is divided into two halves by an invisible wall - one side is densely covered with bookshelves and countless classics; the other side is vast and boundless, like an endless ocean of knowledge.
Interpretations that arise naturally in consciousness:
This is "Mind Palace".
The smaller half represents his six hundred years of knowledge;
And the huge other half belongs to Ian.
He was stunned for a long time before he smiled bitterly:
"My six hundred years of accumulation are actually not as good as a young man in his twenties."
Ian's figure emerged in the light and shadow.
"Mr. Flamel, what is preserved here is not only knowledge, but also memory.
If there is anything you don't want me to see, please hide it."
"Understood." The old man nodded.
Ian raised his hand.
"Then--let's begin."
A book flew out from the bookshelves on both sides, and they were slowly exchanged.
The pages of the book turned automatically, the runes flickered, and they moved like breathing.
As the pages of the book turned, it seemed as if there was an invisible force flowing between the two of them. Every intersection of the pages was like a collision of knowledge, and new understandings poured into their minds like a tide.
The core of this unique knowledge exchange method is "Equivalent Exchange". Every time a book is exchanged, both parties can gain valuable experience and theory in the corresponding field. It is like a feast of ideas, and both parties can learn from the other party's books the wisdom of unexplored fields.
In this process, they are not only reading books, but also exchanging each other's thoughts and opinions. Each book is like a key, opening a door to a new field of knowledge. And this exchange of knowledge also makes their vision broader and their thinking more flexible.
However, they all know that this exchange cannot be completely fair.
The value of knowledge can never be accurately measured.
So they kept repeating it.
One, two, ten...
Until the entire Mind Palace echoes with the torrent of light.
Flamel sighed in the bottom of his heart.
"It turns out that this is the thinking speed of Master Alchemy in the new era..."
And Ian is silently understanding the insight of this ancient scholar.
Six hundred years of experiments and failures, achievements and sacrifices were all compressed into symbols and flowed in his consciousness.
