Harry Potter and the Great Old Ones.

Chapter 789
"It can't be used to become a god?" Hermione asked. "Don't you want Nicholas Flamel to become a god?"

“Of course I hope he becomes a god!” Tierra denied Hermione’s guess. “He lived for over six hundred years, he’s a living history book, and also the father of Western chemistry and the king of alchemy!”

"Even with my divine power, I cannot bridge the gap in knowledge between him and me!"

“Then Tierra, you…” Hermione seemed even more puzzled.

“Because this isn’t the keyhole that made him a god.” Tierra smiled slightly, waved for Hermione to wait a moment, and then took out a somewhat worn magic book from the second drawer of her desk and handed it to Hermione.

“This book contains my research materials on the Philosopher's Stone, and it also includes some records about elixirs of immortality. If you're stuck for ideas, you can take a look at this notebook first; perhaps it will give you some inspiration,” Tiera said gently.
Hermione took the book and began browsing through the pages. The book contained detailed descriptions of the Philosopher's Stone, as well as some experimental records and theoretical analyses—

However, it is very disorganized, because most of the records are not even connected, as if they are records of theories and experiments from countless different authors from different eras.

Even so, she became completely absorbed in it and couldn't extricate herself.

"Snap—" Tiera snapped her fingers.

“You can look at the notebook when you get back,” Tierra said.

"Oh, okay, thank you," Hermione snapped out of her daze in an instant.

“You can use the experimental equipment in this classroom anytime,” Tierra continued.

“Thank you! Thank you, Tyella!” Hermione replied excitedly.

Hermione, clutching the tattered spellbook, left the Dark Arts classroom with great anticipation and went to the Gryffindor common room, eagerly beginning to study its contents.

Hermione leaned back on the large sofa in the Gryffindor common room, silently and excitedly flipping through the records about the Philosopher's Stone and the Elixir of Immortality. A cold blue flame burned in the fireplace before her, emanating gusts of chilling air—

This is a modified version of a cooling magic by Tiera. It appears as a flame, but it actually absorbs heat and stores it inside the magic fireplace. When winter comes, the heat inside the magic fireplace will be released.

As Hermione flipped through the notes, she took out a blank notebook from her Invisible Extensions, waved her wand, and wrote something in the blank notebook. Hermione tried to organize them in chronological order as much as possible, adding her own thoughts and understanding.

Hermione intently perused the records concerning the Philosopher's Stone and the Elixir of Immortality, her mind completely absorbed in this ancient knowledge. Every experimental record and theoretical analysis ignited a spark in her mind, prompting her to consider how to piece together these fragmented pieces of information.

She constantly compared the contents of the book with her own knowledge and tried to connect it with other related fields of knowledge, such as mysticism, chemistry, alchemy, ancient literature, and so on.

Hermione!

Hermione heard someone calling her name.

Hey! Hermione!

Hermione realized she had been shoved hard.

"Oh! Ah?" Hermione suddenly woke up, looking around blankly.

Ron and Harry's large faces were staring at her from very close range.
