"The magic word 'sun wheel' describes a dynamic process of rising and changing... It can represent the rising of the sun, the change of will, especially the change of will under the influence of magic... and the road to success, the honor obtained by one's strong will..."

Felix was talking at the podium, but Professor Gsilda Marchbank, who was sitting in the back row, widened her eyes.

She was very old and a little hard of hearing. She was about to use a spell to improve her hearing. This kind of spell would make her irritable if used for a long time, as if there were a thousand bees buzzing in her ears, so she only used it on important occasions, such as the annual wizard level examination. But she suddenly found that before she drew her wand, Felix's voice had clearly reached her ears.

The key point was that she looked around and saw that other people did not feel uncomfortable at all, which meant that Felix had quietly affected her alone.

Besides, when she saw a bright symbol on Felix's palm, she also solved a puzzle. Why did this young man dare to say in front of her, the chief examiner, that "this part of knowledge may appear in the OWLs exam"...

Because it is a practical ancient rune. In addition to this young professor and his students, there are not many people who have the most say in this field.

At most, there are some alchemists, but they have only dabbled in it slightly, and their research direction is still the application of runes in alchemy.

In addition to these people, the people from the Wizard Examination Administration Bureau are not good enough, and the people from the Ancient Rune Association are not good enough. She glanced at the old man with round eyes next to her, and she knew very well that they were not good enough either.

A student raised his hand.

"Ms. Greengrass?"

"Well, so this is a dual-purpose rune? It is both a translation rune and a practical rune?" Daphne asked.

"That's right," Felix nodded at her, "You can understand it this way."

At this time, Hedstrand Vera, who was sitting in the back row, stared at the magic rune symbol in Felix's hand for a moment, wiped his eyes in disbelief, and showed an ecstatic expression on his face. He raised his hand like Daphne and looked at Felix eagerly.

"Well... Mr. Vera?" Felix said, trying not to laugh.

"That's right," Hedstrand Vera opened his eyes wide and said in a triumphant tone, "I also learned this magic rune, but the way I learned to write it is not quite the same as yours." He pointed at the magic rune symbol with his fat finger and said, "And I'm sure yours is also different from the one marked in the "Magic Symbol Collection". The correct way looks like... uh..."

On the podium, Felix adjusted the speed of his speech and tilted the symbol in the air slightly, adding a little arc on both sides, "Is that so?"

Strangely, when he did this, the magic rune immediately became dim and lost its spirit.

"...That's right." The old man showed a puzzled expression.

Felix looked at the people under the podium.

"Thank you for your reminder, Mr. Vera," he said happily, as if he was expressing his gratitude sincerely, "This is also what I need you to pay attention to."

The students stared at him.

"I have recently made a new discovery: many of the magic runes that are considered translation runes are actually deformations or misrepresentations of a certain practical magic rune. I guess it may be caused by a long period of time... So I plan to review the knowledge you have learned in the past in the near future."

"For example, in this example, the translation magic rune looks like a lightning with a slightly curved line, or a flat and tilted letter 'S'; while the practical magic rune," Felix readjusted the magic rune in his hand so that the students could see the whole change clearly, the curved lines were gradually straightened, like

"a flipped capital letter 'N', with the upper and lower ends sticking out." He said. The symbol in his hand was also re-lit, flickering with a dim light.

Hedstrang Vera's face flushed red, and he couldn't speak.

"The evidence is in the magic notes of two medieval wizards in the library, "The Will of Magic" and "The Notes of Derek Pudlin". They come from a powerful wizard and an apprentice wizard respectively. This can be judged from the depth of the content recorded by the two people... When they use the same magic rune, the writing methods are obviously different. It is reasonable to guess that the former knows the true appearance of the magic rune, while the latter just copied it, or was lazy and saved trouble..."

Hedstrang Vera looked around. The students were busy taking notes with their heads down. Only he had nothing in front of him... He suddenly thought of a good idea.

Crabbe felt that his back was poked hard, and then he heard a low voice saying, "Little Fatty!"

Little Fatty?

He turned his head angrily and stared at Hedstrang Vera, whose figure was also not well-proportioned, with a bad look. After a few seconds, he realized that the person behind him was here to listen. He looked at the vice president of the Ancient Magic Rune Association stupidly, as if he had been hit by a dementia curse.

"Little Fatty! Hey!" Old Vera waved his wand in front of Crabbe, "Lend me your parchment and quill so I can make copies."

Crabbe made a confused expression, as if he didn't understand at all.

Old Vera stared at him, and after a few seconds of stalemate, he pointed his wand flexibly: "Parchment flies over, quill flies over... Very good, make a copy in pairs! Make a copy in pairs!"

Old Vera looked at the copies in his hand and nodded with satisfaction. "Here, your stuff." He returned Crabbe's stuff to him. Then he began to take notes.

He must check all the information that kid mentioned. Who knows if it was just made up? He must not let that kid get away with it!

As he took notes, he thought indignantly, and soon filled a piece of parchment.

On the podium, Felix looked down at everything, and his voice had a happy ending. He had been looking forward to this scene for a long time, and he knew that Professor Marchbank and Old Vera planned to stay for a long time, which meant that he could prepare more similar courses.

Thinking Classroom, Stone Basin, and even Classroom 7, all of these can be considered.

The only thing that made him hesitate was that Felix had not yet decided whether to show the students' true level. He estimated that he had the right to make suggestions on practical magic runes, but he might not be able to get a say in translation magic runes.

If the difficulty was really increased, it would be... afraid that it would be... eh? It didn't seem to be a big deal.

Felix pondered that there were only so many translation magic runs, and the scope of the exam would not exceed the content of the magic notebooks that had been discovered.

In addition, the Ancient Magic Rune Association would publish a magazine every once in a while, and the interval between publications mainly depended on when new results appeared.

The Hogwarts library ordered a few copies, and according to his observation, basically no one read them. The magazines published twenty years ago were still as good as new. He could finish reading them in a morning on a weekend.

...

Finally, the bell rang and the students filed out, leaving only three adults in the classroom. Felix was about to say something when the short Professor Marchbank sprinted up, grabbed his hand and asked:

"What spell did you use just now?"

"It's just a simple application of the amplification spell." Felix answered in confusion.

"Simple application!" Professor Marchbank looked at him in surprise, "It seems that you haven't fallen behind in your study of spells... But do you have any good methods for the hearing loss of the elderly?"

"Of course, I know a spell: 'Sharp ears and bright eyes', Professor Flitwick has done a lot of research on this..."

Felix smiled and talked to Professor Marchbank, which to a certain extent eased the embarrassment of the other person.

Hedstrang Vera breathed a sigh of relief. He was suddenly afraid to face this young man alone. Felix Hep used a class to shake the career he had insisted on for half a century.

He looked a little dazed, and his granddaughter's chattering every time she came back was vivid in his mind.

"Mr. Vera... Mr. Vera?" A voice seemed to come from the sky.

"What's wrong?" Old Vera replied casually.

"...Nothing," Felix looked at him calmly, "Just now Professor Marchbank asked for your opinion. After all, she doesn't know much about ancient magic runes. It is said that you volunteered to join."

"Oh, uh," Old Vera straightened up, put on a face ready to participate in a duel, and said righteously: "Ahem! We can't jump to conclusions at present... There are many vague places. I need to check, uh, I mean, I need to sort it out."

"Of course, no problem." Felix said with a smile: "Then it's settled, I'll wait for your report." He sighed pretentiously, "Professor Marchbank, Mr. Vera, you two may not know that I have been under tremendous pressure in the past two years..."

"Pressure?" Professor Marchbank looked at him suspiciously.

Old Vera also showed a surprised expression and planned to listen carefully.

"...Yes, you two may not know that I did not choose the advanced class of ancient magic when I was in school. In the past few years, I have been relying on self-study and correspondence with Professor Babel to improve. So when I first joined, I was afraid that I would teach students badly."

Professor Marchbank looked at him with a strange expression, and the wrinkles at the corners of her eyes were stretched because of her wide eyes. She rarely confirmed with a hesitant tone: "You said you were afraid that you would teach students badly, but among the students who graduated last school year, except for one student who was good, all the others were excellent?"

"Uh..."

"And as far as I know, one-third of the students who took the exam at that time finished the test paper in advance." Professor Marchbank said slowly: "Although I am hard of hearing, I was impressed by the chat between a couple after the exam."

"What did they say?" Felix asked lightly, as if he was really curious.

"One of them said: 'The test paper is so simple, I checked it five times and it's not time yet, I'm about to vomit.' The other said: 'It's just this time, bear with it, I checked it six times..." Professor Marchbank pursed his lips and repeated dryly.

Old Vera also stood there dumbfounded. The Ancient Magic Association was responsible for part of the OWLs exam questions each year. He couldn't help but clench the parchment in his hand. There were still a bunch of questions waiting for him to confirm.

For the next few minutes, the three of them pretended that the conversation just now had never happened.
