At seven o'clock in the evening, Hermione walked into Professor Hep's office on time, just like she had done in the past two months.

But this time, she felt a little uneasy.

Felix looked up and saw that the little witch was a little restrained. He smiled and said, "Sit down quickly. I thought you would be free for a week. After all, you stay here most of the day."

Hermione plucked up the courage to say, "Professor, I'm sorry. We followed you because we were tracking clues about the Chamber of Secrets and happened to find you in the Forbidden Forest..."

Felix understood a little, "So I'm the one who was suspected..."

"No, professor, you are very outstanding. It's us who are too sensitive," Hermione explained quickly, "Last school year we met a professor who was a dark wizard and wanted to steal the Philosopher's Stone hidden in the school."

"Oh, with such an experience, it's no wonder you are suspicious. But I still want to advise you that maybe your starting point is good, but you have to do what you can. Many dangers do not change because of whether a person is despicable or noble."

Hermione nodded obediently.

The two of them stayed in the thinking hut for five thinking hours, and Felix taught her three runes.

This time was determined by their repeated comparisons, so that they would not be too tired, nor would they learn nothing. Hermione even had some energy left. After returning to reality, she continued to practice for more than ten minutes, and was barely able to draw out the three runes.

"Very wonderful." Felix couldn't help but applaud.

If he were in her shoes, he might not be better than her if he didn't have the golden finger.

But he also found a shortcoming of this little witch. The power of the magic she mastered seemed to be always mediocre, and the fluctuations were not big - this was a good thing to a certain extent. The spellcasting was stable, and once learned, it was difficult to fail.

But sometimes it was also a shortcoming, such as she was unlikely to "explode" and could not rely on strong emotions to amplify the power of the spell.

It can be said that she is more suitable to be a magic scholar, studying magic and learning magic, rather than becoming a spellcasting wizard like an Auror.

Felix thought, maybe after she graduated, he could let her become his research assistant, or - a partner?

You can't blame him for thinking too much. There are too few qualified candidates. This is also what he is dissatisfied with Hogwarts and the wizarding world. The training method is too extensive. How many wizards are still studying magic after graduation?

On the contrary, there is no shortage of such wizards in the black market, but the key is, do he dare to use such people?

If I can dominate the wizarding world... an idea came to his mind, but he quickly abandoned it. That is not his way.

"It's still early. You can go back early, or watch a movie together?" Felix came back to his senses and looked at the time. It was just after nine o'clock. He asked the little witch.

Hermione smoothed her hair. "Oh - Professor Hep?" She stammered. "I think - I'm curious about some potions and hope to know some background knowledge."

"Potions?"

"Yes, you know, we learn about antidotes, hiccup potions and the like in Potions class, but I've read in books that some potions, some advanced potions, have very magical effects..."

"That's true." Felix thought about it and thought it was not a big deal. "Potions, let me think about it." He waved his wand and tapped the ring on his left index finger lightly. Six small bottles as thick as fingers appeared in front of him.

"The field of potions is indeed complex and magical. Although I have attended Professor Snape's advanced class, I have to say that I am still far behind in the field of potions alone."

Hermione was a little surprised. Professor Hep actually praised Snape so much?

"The first one is the Buffy Brain Refresher." Felix flew the first vial on the left to Hermione. "It can significantly enhance the brain power of the user and speed up learning efficiency. To some extent, it is similar to the Thinking Cabin."

Hermione looked at the vial in front of her, which was filled with light blue liquid. When she shook it gently, a bright fluorescent light flashed.

"Many wizards abused the Buffy Brain Refresher and became addicted to potions. They couldn't extricate themselves and completely lost their ability to think." Seeing Hermione's outstretched hand tremble, he added, "But it's okay to take it once in a while."

"The second one is the Fireproof Potion." A small bottle of purple liquid flew in front of her. "Although the name is not conspicuous, it can effectively prevent the harm of magical flames."

Hermione suddenly remembered the level set by Professor Snape during the first grade "challenge".

It was a logical reasoning question, and the function of one of the potions was to pass through magical flames.

"The third one is the Felix Felicis." A small bottle flew in front of her. The potion inside was the least, only one-third, probably only two or three milliliters. But it was the most beautiful one - it was a liquid like melted gold, and with a slight shake, droplets would jump up like swimming fish.

"Also known as the lucky potion, it can make everything go smoothly for the user, as if with divine help. But the result of abuse is dizziness, recklessness and arrogance..."

"It must be very complicated to brew, right?" Hermione asked.

"It is extremely complicated, and it takes at least six months. If you make a mistake in one step, it will become a pot of poison." Felix said with emotion.

"The fourth one is the wolfsbane potion. It can prevent werewolves from losing their minds after transforming at the full moon. Of course, it is of no use to me, it is just for collection..."

"The fifth one is the polyjuice potion." Hearing this, Hermione was shocked and stared at the small bottle that flew in front of her. "It seems you have also heard of this potion?"

Hermione whispered, "Professor Snape mentioned in class that it can allow the drinker to change into someone else."

"Yes, this is also a relatively complicated potion, and it takes a month to brew. A standard dose lasts about 10 minutes to 12 hours, depending on the quality of the potion." "What about

yours?"

"Mine? Probably enough for one person to transform for half an hour."

Hermione was a little disappointed. It seems that she still has to brew it herself. The problem is back to the starting point. How can she get the professor's signature and get the formula?

Felix's explanation continued. He waved his wand and let the last vial fly in front of her.

"The sixth one, the aphrodisiac. It is also called the love potion. Once taken, one will fall madly in love with the person who gave him/her the potion."

Hermione couldn't help but open her mouth.

"You will find that its method of use is somewhat similar to Polyjuice Potion: Polyjuice Potion is to add other people's hair or body tissue to change into someone else;"

"And the love potion is made by adding one's own hair or body tissue and giving it to others to drink, so that they will fall in love with you."

The little witch said indignantly, "This potion is abominable."

Felix shrugged, "Indeed, it will only give you false love, like a soap bubble - just like its smell, which is exactly the smell you like most in your heart."

Felix waved his wand, and the stopper of the small bottle popped out with a "pop". "You can try its smell - don't worry, it is the purest original liquid and not very dangerous. At least it won't affect your sanity."

Hermione moved closer and sniffed it gently. It was the smell of books, sunshine and her home in the Muggle world.
