The seventh-year male and female wizards filed out of the classroom, with a dazed look on their faces, as if they had not returned to reality. When they reached the corner of the corridor, a brown-skinned Ravenclaw girl announced loudly, "I have reserved an excellent grade in the NEWT exam for Ancient Magic!"

Her words were like turning on a switch in them, and discussions poured out -

"Ha~ I thought so too!"

"This class is so wonderful, I can't imagine that the next class is scheduled for Friday..."

"Yeah, compared to Professor Happ, my mind is full of weeds."

"Do you think what Professor Happ said makes sense?"

"Well, I was planning to join the Ministry of Magic, but now I'm a little shaken. My parents are both employees of the Ministry of Magic, and their lives are not as good as outsiders think."

"Really? Are you willing to talk about it..."

Penelope came close to Percy and asked in a low voice, "Is your goal still the Ministry of Magic?"

Percy hesitated for a moment or two, and then he became firm: "Yes, I also yearn for the future described by Professor Happ, but I must grab what I can reach."

"But you won't miss the professor's class?"

"You're kidding," Percy said, "I'll do my best!"

In the following day, these seventh-year students appeared in other classes. Their unusual excitement and free state attracted the attention of other professors. Felix's behavior and words also spread among the professors.

Felix thought someone would talk to him, and he even prepared his words, but everything was calm.

In the evening, he recorded his experience in the office-

'The magic of the mind hut is getting stronger and stronger, even I am a little unfamiliar with it. In the absence of resistance or obvious defense, I can instantly pull the surface consciousness of more than ten or twenty people into the mind hut, which is also the basis of today's class. From here, two branches can be extended-'

'The first branch, the direction of attack; but the mind hut cannot really hurt the other party. After all, it is only the external reflection of the real consciousness. If the other party resists, it will fail. It is difficult to use it in actual combat in a short time;'

He stopped and drew a line on 'It is difficult to use it in actual combat in a short time'. Just the looming terrifying prospect shown in this direction, he could not give up.

Just think about it, at some point in the future, he will knock down a bunch of wizards with just one look...

'The second branch, the auxiliary direction, is used for speeding up thinking and teaching ancient magic. The former is very useful in both combat and learning, and the latter -'

Felix stopped to think, 'The combination of the mind hut and memory magic is equally amazing, and I have a chance to become the greatest teacher in history. '

He thought again: 'I don't know whether I should be thankful or regretful that memories cannot be infused. This is because a person's memory is a very delicate thing. Rash changes will cause unpredictable consequences. Even my oblivion can only reduce the side effects as much as possible, not eliminate them.

In most cases, the memory cancellation personnel of the Ministry of Magic only erase the memories of the last few hours, but the people whose memories are erased will generally be accompanied by forgetfulness and slow reaction for one or two days, or one or two weeks... I have verified this myself from the dark wizards.

And if you want to instill knowledge, it is not a few, slight changes. The impact on people is simply too great...

I have barely bypassed this limitation now, and its real effect is still to accelerate learning. '

Felix's mind flashed through a series of names: Severus, Dumbledore, Lockhart, Ms. Ravenclaw, Mr. and Mrs. Longbottom... They all helped improve and enhance the Mind Shack, either actively or passively. This is why he was able to use this magic from reluctantly to freely and skillfully in just one and a half years.

Not to mention, he actually experienced a major upgrade of memory magic in the middle, and the strong support of the restricted section of the Hogwarts Library...

Felix twisted the parchment and watched quietly as it turned into ashes silently. In the Mind Shack, the parchment was recondensed.

Felix rolled them into a round parchment tube, pulled a silver-green string from the air, and tied the tube in place.

He deftly climbed over the pile of books on the dark chestnut carpet and stood in front of the dark green curtain. The curtain rolled up automatically without wind, revealing the tall door behind.

He reached out and touched the door without a handle, and pushed it gently. The door opened silently.

This was his true inner world, where all his deepest secrets and memories were hidden.

This was a long room with an aisle in the middle, straight ahead, seemingly endless. On both sides of the aisle were tall bookshelves, on which were placed books of various shapes and styles, and each cover showed himself at a different stage.

In the corners of the shelves, there were also some notebooks, photos, memory balls, and similar odds and ends.

Felix strode forward, and the room gradually became brighter. He stood in front of a bookshelf, and in the soft light, he patiently counted the numbers: "Memory Magic - Thinking Hut - Theoretical Derivation - Got It!"

He put the small cylinder on the shelf and muttered to himself in a slightly distressed tone: "Well, the room is always changing, and I have to look for it for a long time every time I come..."

Felix came out of the room behind the curtain, watched the dark green curtain fall again, covering the heavy door, and turned back to the real world.

In the Ancient Rune Office, he looked at the time and waited quietly -

"Knock knock knock!"

"Come in -"

The door of the office was opened, and Hermione jumped in like a thief.

"No one found out, Miss Granger?"

"No, Professor. You told me to keep it a secret." Hermione said briskly. As early as two hours ago, when she was having dinner, Professor Hep's patronus suddenly appeared with a blank card in his mouth.

When her magic covered the card, a line of small words appeared on it: Time Converter, 8 o'clock tonight, confidential.

Hermione waited anxiously until after nine o'clock, and then used the time converter to go back two hours ago and appeared here.

Felix nodded, and he asked, "What do you think of Sirius Black's attack yesterday?"

He intended to use this sentence as a beginning to lead to suspicion of the mouse Scabbers, but Hermione gave him a surprise, or a shock.

"Professor, we guess - Ron's mouse, there might be something wrong!" Hermione said in a low voice, her voice trembling with excitement.

"How did you find out?" "It

was Harry," Hermione said, "He overheard the conversation between Mr. Weasley and Mrs. Weasley the night before the start of the third year. Mr. Weasley said, he said -" She held her breath, her eyes widened.

"After Black escaped from prison, the Ministry of Magic went to Azkaban to investigate and collect evidence. The guards inside mentioned that Black had been repeating in his dreams for the past few days - he was in Hogwarts, he was in Hogwarts..."

Hermione's voice became sharp: "We thought Black's target was Harry before, but yesterday's attack proved that it was not, at least not the first target. In addition, Black's abnormal behavior was actually after Fudge gave him a newspaper - oh, this is what Fudge said himself, when the three broomsticks talked to the professors - combined with Black's attack on Ron, we speculate that it was the "Daily Prophet" where Ron's family's winning information was published..."

Hermione was still talking about her thoughts, but Felix couldn't help sighing. He admired Hermione and their sharpness, and was dissatisfied with Fudge's negligence. After all this trouble, the root of all this was him.

But speaking of it, Harry and the others actually got this information a long time ago, but they didn't really connect them together until yesterday. He was not so lucky. He made the connection based on Black's Animagus and Black's abnormal attack on Ron.

The most crucial clue here is actually Animagus. Following this line, many things can be deduced.

"...We haven't told Ron yet. Oh my God, we can't be sure, but if it's true, he will be so sad."

"Miss Granger," Felix sighed, "There is indeed such a possibility. This is why I asked you to come. I originally thought--"

He shook his head slightly, "I need to change my strategy."

"Since you have investigated to this point, I hope you can realize the possible danger and put protecting yourself first."

Felix stretched out his hand to summon three coins that can be transformed into Ouroboros rings and let them fall into Hermione's hands. "This is what I prepared for the Magic Rune Club. It's okay to give it to you a few days in advance."

"You can contact me through it in case Harry forgets to bring the snooper again...

In addition, you should always carry your beaded bag with you. It can fight against the basilisk for a short time. When it is suddenly launched, ordinary dark wizards can't be your opponents.

If you find the rat Scabbers, choose to stun it as soon as possible. Don't hesitate, then find a nearby professor to warn, or contact me directly."
