In the following two hours, Kael detailed everything that happened in the Chamber last year.
Nicolas didn't care about the process, only asking many details at the beginning and end, including Kael's feelings when time reversed, any special phenomena around, and even environmental changes.
Some questions Kael hadn't noticed himself; he was busy exchanging knowledge with Riddle and had no mind to pay attention to whether the Chamber was hot or cold.
Two hours later, Kael, his mouth dry, picked up the cold cup of tea on the table and drank it down.
He also suggested using a Pensieve so Nicolas Flamel could look for himself.
As the home of a famous Alchemist, the Pensieve certainly wasn't lacking, and even if it wasn't available, Nicolas could probably make one on the spot.
But Nicolas Flamel shook his head.
"I must tell you, child, extracting memories isn't easy; only those Wizards proficient in Memory Charms can do it."
"And there's another point..." he continued, "If I'm not mistaken, you should have learned Occlumency long ago."
Kael nodded.
Occlumency was the Charm he had studied the longest, never stopping over the years, particularly after Rowena Ravenclaw's reminder.
"Then it's impossible."
Nicolas said, "For Wizards who have learned Occlumency, no one but themselves can extract their memories, not I, nor Albus."
"Actually, I could try..." Kael said, "Hogwarts once had a professor who was a Memory Charm master; he gave me a note documenting all his insights on Memory Charms, from which I learned a lot."
"Oh, Hogwarts had a Memory Charm master?"
Nicolas Flamel looked a bit surprised, "Albus really has an eye for choosing professors; I must admit, in that regard, Beauxbatons falls short of Hogwarts."
"Maybe...that's the case..." Kael chuckled dryly, not daring to mention the current situation of that Memory Charm master.
A professor with the real identity of a fraudster not only lost his memory but was sent to St Mungo's Hospital... mentioning this would be quite embarrassing.
Let the misunderstanding be; reacting isn't important.
Kael hurriedly changed the subject: "I could try..."
"No, it's still not possible!"
He hadn't finished speaking before being interrupted.
"Perhaps you want to say you've made great progress in Memory Charms after reading the notes, but I can't take the risk..."
Nicolas Flamel pointed to his forehead, saying seriously, "Your clever mind is more valuable than what I want to know, so...no!"
"Besides, it's not necessary; from your description just now, I basically understand the situation."
Nicolas Flamel waved his hand, and the surrounding blue lake-colored sculptures and shelves instantly disappeared, replaced by a wall covered in various Magic Text symbols.
Under his direction, several Magic Texts lit up one after another, flashing like stars.
Nicolas muttered, "Unlike existing Time Turners, its ending method seems not to match the original time point, but rather to complete a necessary condition; in this case, these are not needed..."
He waved his hand again, and some Magic Texts on the wall darkened, but more lit up, along with the original ones, totaling hundreds.
Nicolas Flamel continuously changed the positions of those Magic Texts, arranging them into different combinations of Talismans, which then stacked to transform into new forms.
Kael did not interrupt him, watching quietly from the side.
Truth be told, he didn't understand Nicolas's operation at all and could only try to memorize them.
But ten minutes later, Kael gave up.
It was meaningless; remembering the permutation and combination of hundreds of different Magic Texts was practically impossible.
Moreover, Kael noticed that Nicolas seemed to be merely attempting something, essentially drafting, not providing the final answer.
However, what Kael didn't expect was that Nicolas drafted throughout the entire night.
By the time he stopped and the Magic Texts darkened, it was already the next morning.
Having watched Advanced Magical Text all night, Kael only felt dizzy and mentally confused.
In contrast, Nicolas appeared even more energized than the previous day.
"Truly amazing..."
"Sorry, Kael, I forgot you were still here..."
Upon noticing Kael's anomaly, he clapped his hands, summoned Little Elf Tata, and fetched a bottle of light red potion.
"Drink it, it's good for you."
Kael took the potion and gulped down a mouthful.
In the next second, the dizziness disappeared.
"What is this?"
"A type of Awakening Potion I formulated myself," Nicolas said, "I drink some whenever I need memories from hundreds of years ago; it's very useful."
Kael nodded, unable to resist asking, "Is brewing this potion troublesome?"
"Not troublesome at all, very simple."
"If you like..."
Nicolas smiled and tapped the table with his finger, and instantly a piece of Parchment appeared before Kael.
"Consider this my Christmas gift to you."
"Thank you, Nicolas." Kael hurriedly picked up the Parchment.
The Awakening Potion is indeed useful; although he didn't need it much at Hogwarts, it could be used for others.
Just in time, Conna recently started deeply studying Ancient Runes, and this was needed.
Also, Cedric, Cho, and the Weasley Brothers could use it too...
Kael glanced at the Parchment, then couldn't help but twitch the corner of his mouth.
Just as Nicolas said, the brewing method was really simple, requiring only six materials.
But how to put it... the cheapest material was Unicorn horn, priced roughly at fifty Galleons per ounce.
In other words, the brewing cost of this potion at least 300 Galleons.
Kael took a deep breath, expressionless as he folded the Parchment several times, stuffing it into his pocket.
As the two left the room, Nicolas was still thrilled by his earlier discovery.
"I feel I've found the direction." He said, "But it needs multiple attempts and verification, which might continue for a long time like just now.
This isn't very friendly to a 600-year-old man."
They sat at the dining table, and Tata promptly served sumptuous food.
