The young wizards filed into the classroom, and the door of classroom 7 closed automatically behind them.

There was only a narrow path in front of them, with thick fog on both sides. In the thick fog, vague human figures could be seen.

"What kind of monster is hidden in there?" said Roger Davis from Ravenclaw. He was tall and handsome, with dark brown hair combed back, revealing a handsome face.

Although he was talking to everyone at the moment, his eyes glanced at a beautiful girl not far from him.

"Where does he think he is, a dance?" Ron, who was walking behind, muttered, making Harry and Hermione laugh. The wizard named Davis was wearing a high-collared robe with blue and bronze embroidery on the cuffs. When he spoke, he was trying hard to hold his hair back.

A chuckle came from the thick fog, which made Harry stunned. He turned his head and looked at the thick fog. He heard it clearly that the owner of the voice was near him. The fog in front of him floated and dispersed, and there was nothing there. He hurriedly walked a few steps and heard Ron say, "...But who is that girl? She's so pretty!"

From Harry's point of view, the girl Davis was staring at was indeed very pretty, petite, even a little thin. She had a light white complexion, delicate features, and short brown hair. The only flaw was that her eyebrows were too thick and didn't match her face very well. Another thing was that she was a Slytherin.

"Do you know who she is?" Ron pulled Hermione.

"How should I know?" Hermione said impatiently.

"You know at least half of the students in the school, like her so, so..." Ron tried to find an appropriate word to describe it, but he couldn't think of it.

"I only know students who took the ancient rune!" Hermione pointed out sharply.

They walked for more than ten minutes, and Felix, the leader, finally stopped. At this time, everyone realized that they were in the middle of a crossroads. Two long crossroads divided this place into four areas, and each area was covered by fog.

"I'm going to take a look at your papers first." Felix said to everyone, "You can walk around... Although this place is not perfect yet, but..." He smiled, "I believe there will be surprises waiting for you."

As he spoke, he transformed a comfortable armchair for himself and sat down.

The students looked at each other, a little unsure of what the professor meant.

The girl with short black hair said calmly: "Are the things we encountered the same?"

Felix thought for a moment and said: "It has something to do with the area you choose."

"Is it dangerous?"

"It depends on how you define it, but don't forget why you came."

The girl with short hair nodded slightly, drew out her wand, turned around and walked into the thick fog closest to her. The thick fog automatically separated a path, and after she entered, the separated fog quietly closed again.

After a few seconds, the people who stayed behind did not hear any movement.

"Let's pick one too." Hermione said decisively. Harry and Ron saw that Davis had already chased into the area where the short-haired girl entered, and they decided to change direction.

"This way!" Harry pointed to the right and said, he first heard a chuckle here and wanted to go in and take a look.

Ron and Hermione had no objection. "Neville, what about you?" Harry asked. Neville scratched his head. "I'd better go with you. I'm a little worried about being alone."

Malfoy, Blaise Zabini and two other Slytherin students entered a new area. Cedric, Susan Bones, Qiu Zhang, Angelina and others chose the last area.

The rest of the people also chose their directions, leaving only Felix sitting in the middle, quickly flipping through papers.

...

The students were experiencing their own adventures.

Cedric found himself lost, and Qiu Zhang beside him disappeared. After walking for a while, he saw a corner of a building vaguely revealed in the mist. It was a tall and spacious arena. It was a bit like the gilded arena in the duel class, but much larger.

"Professor Flitwick?" When he saw the person standing on the arena clearly, Cedric opened his mouth in surprise.

He thought he would encounter some strange monsters. Professor Hep's eccentric interests had gradually spread, and some young wizards from Muggle families had specially summarized some monsters that often appeared in movies.

A witch who loved watching ghost movies provided him with a wealth of materials. When Qiu showed them to him, although he seemed calm on the surface, he was actually very nervous inside.

The young Flitwick smiled and said, "It's not good to be distracted here. Maybe you are waiting for your companions to come?" He pointed to one side and asked.

Cedric then realized that Qiu Zhang was walking out carefully from another direction, followed by Susan Bones, the Weasley twins and Angelina Johnson.

"Hey! Cedric, you're here first." Fred greeted.

"We waited outside for a while, and sure enough, we caught a few more." George said with a smile.

"Everyone is here. What's your decision?" Flitwick raised his wand. "Are you coming one by one, or together?"

On the other side, in the second area,

Harry saw a young student with reddish-brown hair. He always felt that this face looked familiar, especially his hooked nose. He seemed to have seen it somewhere. This suspicion was not confirmed until he introduced himself.

"Are you Headmaster Dumbledore?" Harry was shocked.

"Headmaster?" The young Albus Dumbledore said with a smile, "I only have memories of when I was the President of the Student Union. Do you want to share them with you, Harry?"

Harry felt that everything in front of him was extremely strange. He saw Dumbledore when he was young, and Dumbledore wanted to discuss the topic of the President of the Student Union with him. He couldn't figure out whether this was a trick. He tentatively said, "Professor Dumbledore, I came in here because of Professor Happ. Are we... uh, are we going to have a fight?"

"Fight?" The young Dumbledore looked at him with a smile, "Of course."

Ten seconds later.

Harry struggled desperately on the ground. His clothes seemed to have become a cage, completely restraining him inside. He couldn't even raise his hands now.

"You were too close to me, and you didn't pay attention to the fluctuations of the spell. I guess you haven't learned wandless spells yet?" said Dumbledore with reddish-brown hair. He waved his hand and dispelled the magic. "Okay, let's try again..."

The third area.

Young Felix yawned, "Are you the only two? There are too few people. It's a bit boring."

Collins Foley gritted his teeth and waved his wand one after another, releasing silent spells one after another. "Bang, bang, bang!" The spell was deflected by one hand. Roger Davis couldn't get close at all. All the spells that Felix seemed to deflect flew towards him. He wanted to ask Collins to stop, but he had no time to spare. He jumped up and down to avoid the spells.

The young Felix said lazily: "Human Armor Charm, do you want to learn it?"

The fourth area.

Draco Malfoy was forced into a corner. A ten-foot-tall lion-headed manticore looked down at him. The scorpion's barb flashed a metallic cold light. He leaned back as far as he could to keep himself away from that thing.

"Mr. Malfoy, I've told you three times not to run away all the time..." Professor McGonagall raised her square glasses and looked at him with a look of disappointment. A row of humanoid puppets followed behind him.

...

After about half an hour, Felix finally finished flipping through the paper.

"Tsk! I wonder what they encountered." He stood up, walked into the thick fog, walked around inside, and led the students out.

These students followed behind with their heads down, looking completely different from when they first arrived, with a look of great shock.

"So, each of you knows at least one administrator of the secret realm. They come from the memories of the four professors when they were young, including myself. So, you may feel that some people's personalities are slightly different from reality. Yes, slightly different..."

Felix said with a guilty conscience, "This is all normal. You have to learn to distinguish them." His own memory was a little too jumpy. Relying on the fact that he would not disappear, when Felix himself went over, he found that his memory was performing a spell with his eyes closed. The girl named Collins was furious...

Although he did think about doing this, he just thought about it and never practiced it. He would not joke about his own safety.

Felix sighed. Whether it was the portrait or the young memory of classroom 7, they were more cheerful and lively than his own personality, probably because he did not give them those dark and secret memories.

This gave him a bad premonition and speculation: If he had not experienced what happened in school, would he have grown up to be a somewhat ridiculous guy like Memory?
