Chemistry... a strange yet familiar word, as if it was a memory from a previous life, Harry thought.

Where on earth did he know this concept? He recalled his elementary school years. It was not a pleasant memory. Apart from Dudley's pranks and humiliation, there was not much he was willing to recall.

Fortunately, he still remembered some of the content in the experimental class. Chemistry should be a subject that changes matter, right?

He picked up "Unreliable Alchemy" with some annoyance and looked at Hermione. "I've read it, Harry." Hermione said. She pointed at a pile of books and picked out the book "The Controversy of the Fifth Element" according to her interest.

"Miss Granger, I suggest you start from Chapter 7. The explanation of the influence of magic on matter is very fascinating. It is the most convincing I have read in recent years." Felix said.

"Oh, thank you, professor." Hermione said happily.

"What about us?" Harry asked. He also urgently needed some advice because the book in his hand was not thinner than Hermione's.

He flipped to the middle at random, and then turned a few pages. He only saw a picture. The wizard in it looked very similar to a portrait hanging on the wall of the old Black house. They all had curly hair and clothes like those worn by court nobles.

Felix looked up at Harry and Ron and smiled kindly, "Start with the preface. One of my experiences in reading books is that basic knowledge cannot be neglected."

"After reading this book, read "The Nine Schools of Alchemy" and you will have a basic understanding of alchemy. It would be best to write a review paper at this time. Of course, using a knowledge graph is also acceptable... Later, when you read "The Complete Collection of Alchemy General Techniques", "Nick Flamel Manuscript 1", or "The Controversy of the Fifth Element", you will not be unable to understand it."

Two swallowing sounds were heard, and Harry and Ron looked at each other.

"Homework for Divination?"

"Just keep making it up." '

They quickly understood the meaning of each other's eyes, each took out a piece of parchment from their schoolbags, and started reading from the introduction. After reading only two lines, Harry couldn't help frowning.

'I am a wizard who is crazy about alchemy. Remember this name, Crofts Albold Adrian. It will always shine in the field of alchemy, more dazzling than Nick Flamel, because I will be the first person to conquer the Philosopher's Stone. '

'Some people may say that Nick Flamel is the first alchemist to uncover the mystery of the Philosopher's Stone, but I think this is a misunderstanding, because the Philosopher's Stone can make an elixir of life without side effects. If he really made the Philosopher's Stone, we would not be unaware of it... and I would immediately find him and worship him as my teacher. But the fact is that he has disappeared long ago. '

Harry heard Ron mutter: "It is because of people like you that he hides." He grinned and thought it made sense, and they continued to read on.

'There has never been a lack of alchemists who claimed to have refined the Philosopher's Stone in history. Such claims are like those wizards who once obtained the legendary magic wand, claiming to be invincible, but disappeared from our sight forever. Adrian's comment on this is: Honor is the reward for hard work, who would have the heart to give up? Similarly, we can speculate that if those who are said to be able to prolong life and defeat the god of death really succeeded, what reason would they have to hide from people? Is it because they have incurable dragon pox on their faces? ' '

Next, I will introduce my own experience to you. I, Crofts Albold Adrian, an alchemy genius, graduated from Hogwarts Ravenclaw College. After graduation, I spent a lot of time traveling, visiting those famous alchemists one by one, converging their ideas, correcting their mistakes, and finally compiling my first book. I will dedicate it to my alma mater, the greatest magic school Hogwarts. If future students read this, they will learn about my outstanding achievements from my other books...'

Harry felt that this 'Adrian' sounded too much like Lockhart, and he wanted to ask Ron for his opinion. Ron whispered, "I suddenly want to find out if this person has published a second book. I mean... there is always a possibility of accidents. Maybe our genius friend runs out of inspiration, or encounters a Hungarian Horntail out for food while on the road." ... Felix was examining

his

magic Shield Charm, thinking about how to combine them into one. More than two months have passed since he returned from Beauxbatons, and the Beauxbatons version of the Shield Charm has successfully reached level six.

It seemed to have undergone sublimation, fading the rusty battlefield scars on the surface, becoming smooth and shiny, and its color also turned into a beautiful blood red, as if it was cut from a huge ruby.

At this time, Felix held a mask with a very metallic texture in one hand. It was part of the complete armor. The left hand was golden and the right hand was blood red. He looked at it carefully for a long time, but still had no clue. Felix's initial idea was to block his memory of the Shield Charm and learn it from scratch, and the two Shield Charms would naturally merge in the end.

But this guess was proven to be wrong.

He put his two palms together, and the gold and blood-red armor masks collided with each other, making a crisp metallic sound, but there was no sign of fusion. He couldn't help but wonder if his magic theory was not enough to understand and accommodate magic of this intensity?

Felix casually covered his face with the blood-red mask, and his vision turned into a blurry blood-red, as if covered by a layer of red scarf. He raised his head and looked around the library, using this new perspective to observe the students sitting in the distance.

There was a slight noise next to him.

Felix glanced over and saw Hermione covering her mouth and laughing. When he looked over, she immediately frowned.

"Professor, what is this?" She whispered, and in his peripheral vision, he saw Madam Pince inspecting through the gap between the bookshelves.

"The embodiment of the Shield Charm," Felix explained, "both of them." He handed her the golden mask, "How do you think they should be combined?"

"Sixth-level spell?" Hermione took it with great interest and examined it carefully. She thought for a moment and asked, "Is it the one that helps the Beauxbatons warriors resist the flames?"

Felix nodded slightly, and he briefly introduced the origins of the two forms of the Shield Charm.

Hermione pondered, but the question was too profound for her, and she could only guess without basis, "Is it related to the understanding of magic?"

"That's a possibility," Felix nodded, "This is one of the directions I guess, but" He looked at Hermione speechlessly as she also put the golden mask on her face and looked at him.

"Is it fun?"

Hermione secretly made a face behind the mask, took off the golden mask, and said seriously: "Will there be a new form of magic above the sixth-level magic, like the magic rune ball? It should cover the two armor spells of gold and blood red... I guess it must be difficult!"

Felix sighed, "The problem is that I don't have any ideas, although I know I can do it, it's just a matter of time." But when he vaguely saw a higher realm, he felt itchy.

"You can ask Headmaster Dumbledore," Hermione suggested.

"We haven't seen him recently, maybe our headmaster is traveling." Felix shook his head and said, he didn't elaborate on how he went to the headmaster's office with his Patronus in the morning and was stopped by the monster statue at the door.

He guessed that Dumbledore was still tracking the whereabouts of the Horcrux, maybe he was chatting with the owner of Borgin and Burke's now? At least he knew what gift he should give him for Christmas, a dark magic exploration device or a woolen cloak.

"Your advice is very useful, Granger," he said, waving his hand to dispel the magic.

Felix left soon, he had classes in the afternoon. When he disappeared, Harry handed Hermione a newspaper.

"What's wrong?"

"Borrowed from the next table," Harry said simply. "Take a look at page 4."

Hermione quickly flipped through the newspaper of the day, her eyes paused slightly on the gloomy photo of Durmstrang's headmaster Karkaroff. The title was "Are cheaters still qualified to be referees?" Not surprisingly, she saw Rita Skeeter's name in the reporter column. She was sincerely glad that the woman did not focus on them, and even felt incredible that she had escaped.

She quickly turned to page 4. It was a small article, an interview with the head official of the Wizard Examination Bureau. She knew that this should be the views of Professor Gesilda Marchbank mentioned by Professor Hepp in class.

She glanced at ten lines and found those "sharp and inspiring" contents.

Reporter: What do you think of Hogwarts' performance in the first project?

Marchbank: I am proud.

Reporter: Are you surprised that the two teams won the first and second place respectively?

Marchbank: No, I think it's normal. This shows that we have walked out of the shadow of the war.

Reporter: Some people say that the educational achievements of Hogwarts are the result of Minister Fudge's coming to power. What do you think?

Marchbank: Oh, that person is talking nonsense.
