Nico didn't care about the process, but when it came to the beginning and the end, he asked a lot of details, including Kyle's feelings when time went backwards, whether there were any special phenomena around, and even the changes in the environment.

Even Kyle himself didn't notice some of these problems. He was busy communicating and studying with Riddle at the time, so he didn't have the time to pay attention to whether the secret room was cold or hot.

Two hours later, Kyle, feeling thirsty, picked up the cup on the table and drank the cold tea in it.

During this time, he also suggested using the Pensieve so that Nicolas Flamel could see for himself.

As the home of a famous alchemist, there is no shortage of things like Pensieves, and even if there isn't one, he can probably make one on the spot.

But Nicolas Flamel shook his head.

"I must tell you, kid, that retrieving memories is not an easy task. Only wizards who are proficient in memory spells can do it."

"And there is another point..." He continued: "If I am not mistaken, you should have learned the brain block a long time ago."

Kyle nodded.

Occlumency was the spell that took him the longest to learn, and he had never stopped studying it over the years, especially after being reminded by Rowena Ravenclaw.

"That can't be helped."

Nico said, "For those wizards who have learned Occlumency, their memories cannot be retrieved by anyone except themselves, not by me or Albus."

"Actually, I can give it a try..." Kyle said, "There was once a professor at Hogwarts who was a master of memory spells. He gave me a notebook that recorded all his experiences with memory spells. I learned a lot from it."

"Oh, is there a Memory Charm Master at Hogwarts?"

Nicolas Flamel looked a little surprised, "Albus has a really good eye. I have to admit that Beauxbatons is indeed not as good as Hogwarts in terms of the choice of professors."

"Maybe... that's the case..." Kyle laughed dryly twice and was too embarrassed to tell the specific current situation of the Memory Spell Master.

A young professor who is actually a liar not only lost his memory but was also sent to St. Mungo's... It's really embarrassing to talk about this.

It's just a misunderstanding, the reaction is not important.

Kyle quickly changed the subject and said, "I can try..."

"No, it still doesn't work!"

He was interrupted before he could finish his words.

"Perhaps you would like to say that you have made great progress in memory charms after reading the notes, but I cannot take the risk..."

Nicolas Flamel pointed to his forehead and said seriously: "Your head is more valuable than what I want to know, so... No! "And there is no need. Through your description just now, I basically understand the situation."

Nicolas Flamel waved his hand, and the surrounding blue lake-colored reliefs and shelves disappeared instantly, replaced by a wall covered with various magic symbols.

Under his command, magic runes lit up one after another, flashing like stars.

Nico murmured to himself: "Unlike the existing time converter, the way it ends does not seem to match the original time point. Instead, it seems to be more like completing a necessary condition. In this case, these will not be used..."

He waved his hand again, and some of the magic runes on the wall dimmed, but more magic runes lit up, and together with the original ones, there were almost several hundred of them.

Nicolas Flamel kept changing the positions of the magic runes, arranging them into different combinations of symbols, and then superimposing these symbols together to form new shapes.

Kyle didn't disturb him and just watched quietly from the side.

To be honest, he couldn't understand any of Nico's operations, so he could only try to remember them all.

But after ten minutes, Kyle gave up.

There's no point. There are hundreds of different combinations of magic runes. It's almost impossible to remember them all.

Kyle also discovered that Nico seemed to be just making some attempts. In other words, he was just making a draft, not the final answer.

By the time he stopped what he was doing and all the magic runes had dimmed, it was already the next morning.

After reading advanced magic words all night, Kyle felt dizzy and dazed.

Nico, on the other hand, looked more energetic than yesterday.

“It’s incredible…”

"Sorry Kyle, I forgot you were still here..."

After noticing Kyle's abnormality, he clapped his hands and asked the house-elf Tata to bring a bottle of light red potion.

"Drink it, it's good for you."

Kyle took the potion and took a big sip.

The next second, the previous feeling of dizziness disappeared.

"What's this?"

"A brain-stimulating potion I made myself." Nico said, "I drink some whenever I need those memories from hundreds of years ago. It's very useful."

Kyle nodded and couldn't help asking, "Is it troublesome to brew this potion?"

"It's not a hassle at all, it's very simple."

"If you like..."

Nico smiled and tapped the table with his finger, and a piece of parchment suddenly appeared in front of Kyle.

"Consider this my Christmas present to you."

"Thanks, Nico." Kyle quickly picked up the parchment.

This brain stimulant is indeed useful. Although he didn't really need it when he was at Hogwarts, he could give it to others.

It just so happened that Kanna had recently begun to study ancient runes in depth, and this was exactly what she needed.

And Cedric, Cho, the Weasley brothers, they can all be used too...

Kyle glanced at the parchment, and then the corners of his mouth couldn't help twitching.

Just like Nico said, the brewing method is really simple, and only six ingredients are needed.

But well… the cheapest material is unicorn horn, which sells for about fifty galleons an ounce.

In other words, the cost of brewing this medicine is at least three hundred Galleons.

Kyle took a deep breath, folded the parchment a few times expressionlessly, and stuffed it into his pocket.

When the two left the room, Nico was still excited about his discovery.

"I feel like I've found the direction," he said, "but this requires multiple attempts and verifications, and situations like the one just now may continue for a long time.

That’s not very kind to a 600-year-old man.”

They came to the dining table and sat down, and Tata immediately brought a sumptuous meal.
