The office of the professor of ancient runes.

Felix was marking homework. This job was really boring. It gave him the illusion of adding 1 and 1 hundreds of times. Fortunately, when he handed over this job to Hermione, who had just knocked on the door and didn't know the situation, he was completely liberated.

"It's mainly the test papers for the fifth and seventh grades, which are mainly multiple-choice and short sentence translation. It's relatively simple to mark - you just need to compare the correct answers and cross out the wrong ones."

Hermione lived up to her reputation as a top student and quickly got into the state. Moreover, she was very good at this kind of work.

Felix flipped through the paper that Hermione had revised - this was to be handed over to Professor McGonagall to be published in an academic journal, and he had to strictly check it. However, he did not simply and crudely revise it directly, but kept making suggestions and giving the page numbers of reference books.

He thought this method would help Hermione more.

Half an hour later, the two finished their work almost at the same time.

"Okay, let's get to the point."

Before, Hermione was fulfilling her assistant duties, and now Felix needed to fulfill his promise.

The two sat on the sofa facing each other, with a small low table between them. Felix used his wand to summon two glasses of juice. He tried to make Miss Granger relax, but she still seemed very reserved.

"From your thesis, I can see that you have a sufficient understanding of the history of ancient magic runes. Even if you haven't started learning yet, I can assure you that you will make rapid progress."

"Professor, I am reading "Ancient Magic Runes Simple Introduction". I have also learned how to consult the "Magic Runes Dictionary" and "Magic Symbols Collection", including the list of books you gave me before, but I don't fully understand most of them." The little witch sat up straight and quickly introduced her latest learning progress.

Felix was stunned for a moment, "Very good, but I won't spend too much time discussing with you how to translate. At most I can give you some suggestions."

"You can start from around 900, when Hogwarts was founded. The four founders were great figures who connected the past and the future. They translated many manuscripts of their predecessors and left behind a lot of research materials that puzzled later generations. These contents filled the earliest library." "However

, this part of the information is now placed in the restricted area. The one preserved by Ms. Ravenclaw is the most complete, while most of Slytherin's information has been lost. It may be that after he split with the other three, he took away his research results in a fit of anger..."

Felix told a piece of history, which made Hermione listen attentively, "However, it is also possible that the content of Slytherin's research is not suitable for the library. Who knows."

"If you need it, I can approve a book note for you."

Felix stood up and motioned Hermione to follow, and the two came to his workbench.

"My research direction is not translation, but to explore the power of magic runes. Just like this -"

He picked up a palm-sized piece of chestnut wood on the table, injected magic power into the carving knife, and carved magic runes on the surface of the chestnut wood. When these magic runes were first written, they quickly burst into a scorching red light, but soon extinguished and turned into dark lines. It was

the first time Hermione saw this scene. She watched intently and racked her brains to try to analyze what the professor was doing, but she found nothing.

Felix finished carving the magic runes and handed it to Hermione casually, "You can feel it."

She reached out to take the chestnut wood piece. Without rubbing it, she keenly sensed the magic fluctuations on it. Her fingers ran over the dark magic runes, and a warm touch came from her fingertips.

"Magic runes can store magic power for a short time, but if it is not processed, the magic power on it can only last for three days at most. This is also the result of the superposition of the characteristics of chestnut wood itself."

Hermione nodded. As a wand material, chestnut wood has excellent ability to carry and conduct magic power.

"There are many solutions to this defect, such as -"

"You can connect them to form a circuit, which greatly prolongs the retention time of magic;"

"You can also apply special protective magic;" "

Or add storage and conversion circuits..."

Hermione's little brain tried hard to remember, she wanted to pick up the parchment immediately and record every word Professor Hepp said.

Felix's explanation process is actually the process of reorganizing his own knowledge system. Unlike the previous three years of "not having enough to eat", he now has too many choices and must choose carefully.

Therefore, giving a lesson to the little witch is a side job. At this moment, he fell into thinking and muttered: "However, these methods are only for maintenance. In thirty or fifty years, they will eventually decay with time."

Why did the voice become smaller? Hermione quickly closed the distance between the two and stretched her neck to listen hard.

"Are the heroes and creatures in mythology imaginary or real?"

"Are they powerful wizards?"

"If so, how do those magical creatures that have been passed down for thousands of years remain immortal?"

Seeing the professor fall silent, Hermione guessed, "Maybe they themselves can provide a continuous supply of magic power."

Felix laughed, "How is that possible? They are not living things."

"What about the Sorting Hat? The Sorting Hat has existed for thousands of years, and it can communicate with people and has its own wisdom." Hermione tried to give examples to support her guess, "And there are also portraits of past headmasters in the headmaster's office. I heard Harry mention it."

"Ms. Granger, the portrait itself is an exquisite magical creation. It can carry a person's thoughts. And as far as I know, if a magical portrait wants to maintain its long-term existence, it also requires regular maintenance, although this interval may last for decades..." "However

, the Sorting Hat," Felix thought for a while, "I did overlook it. I don't know much about it. Maybe I should find an opportunity to introduce myself to it again?"

"Okay, Miss Granger, let's stop our brainstorming journey here. Next--"

Felix took the palm-sized chestnut wood piece from Hermione, "Next, I will connect these magic runes and make them form a circuit. Watch carefully."

This work is quite delicate. He carefully drew out the lines and connected them to each other. He explained while operating, "This step is very important. Many alchemical creations have complex functions."

Ten minutes later, he handed the chestnut wood piece to Hermione and let her feel the difference before and after.

"I feel the magic power flowing, with fluctuations and ups and downs. They... they seem to resist me." Hermione said her feelings with some confusion.

This is really incredible.

Felix understood. "You said resistance because it is a rough semi-finished product, and the magic fluctuations are spreading wantonly, and you felt it."

"Of course, this also shows that you are very sensitive, and you must have a strong talent in magic."

Hermione's face turned red.
