Harry suddenly saw that Snape's trouser leg had been cut for some unknown reason, and there was a deep wound in his thigh.

Noticing Harry's gaze, Snape hurriedly blocked his legs with his robe, as if to hide something, which made Harry wonder a little, could it be that this troll invasion was because of .......?

Harry was startled by the thought in his heart, but he thought that Snape was usually targeted at every turn, and he became more and more sure of the conjecture in his mind.

Professor McGonagall was chattering about the three young wizards, and Chen Yi had followed Dumbledore to his office.

"Sit down, what do you want to drink?"

"Except for Butterbeer, everything else is fine."

"Butterbeer is a good thing, why don't you like it?"

Chen Yi shrugged and wandered around Dumbledore's office.

There are a lot of things in the office, and there are photos of previous presidents and professors hanging on the walls, and the people in these photos are also looking at Chen Yi at this time, and several of them recognize Chen Yi's identity with incredible expressions on their faces.

Chen Yi did not have the people who pointed at him in the photo, and continued the tour.

A row of cabinets against the wall display trophies and medals, documenting the glory that Hogwarts has received. There were several metal instruments on the table that looked like globes, and Chen Yi could sense that there was some magical power contained in them, and after a few flicks, he didn't notice any changes, so he lost interest in them.

A little over was a bookshelf with magic books in it, but looking at the dust on the books, Dumbledore hadn't touched them in a long time.

Through the names on the spine, Chen Yi found that most of these books were biographical books, and the few spell books that recorded some conventional magic were also recorded.

It seems that if you want to learn some powerful attack magic, you can only go to the forbidden book area of the library to find it, and Chen Yi plans to go there when he has time.

At the top of the bookshelf was a worn-out wizard's hat, the talking Sorting Hat, who knew a lot of Hogwarts secrets.

"Hey, see who's here? The famous Dark Witch Hunter! At this time, the Sorting Hat also recognized Chen Yi's identity, shook the tip of the hat and shouted loudly.

"Shut up! If you dare to reveal my identity to anyone else, I'll throw you in the furnace and burn you!" ”

Under Chen Yi's threat, the Sorting Hat decisively shut up, motionless and pretending to be an ordinary hat.

After staring at it menacingly for a while, Chen Yi walked to the next place.

Finally, Chen Yi walked to the side of the stairs and looked at Dumbledore's phoenix, which was dressed in red feathers and was listlessly deaf with its head.

"This thing is a phoenix? How do you look like a big parrot......"

Chen Yi pursed his lips and found that the more he looked at the bird, the uglier it became.

"It's called Fox, and it's Nirvana time for it soon next year, so it looks ...... It's more chic. ”

Dumbledore described his phoenix in a more euphemistic way, and handed over a glass of chilled lemonade.

Chen Yi said thank you.

"If you don't mind, can you tell me where you've been in the past few decades?"

Chen Yi took a sip of lemon juice, thought for a while and said, "During this time, I went back to my hometown to retreat and practice. ”

"Retreat? I think I've seen this term in the books......"

Dumbledore said thoughtfully, there are many mysterious things in the Eastern world, and he only has a vague idea of them from the words of ancient books.

"You know about retreat?!"

This time it was Chen Yi's turn to be surprised, it was completely different from magic in the same system, how did he, an old magician, know.

"Yes, there were many other cultivation systems in the world before the magicians appeared, but I don't know what happened later, these people disappeared from the world one after another, leaving only some ancient books and monuments."

"Monuments? Is there still one now? Chen Yi asked, he didn't expect that there was such an unknown side in the Harry Potter world......

"It's been too long now, and the ruins are long gone."

"In other words, the so-called other systems of cultivation are only inferred from ancient monuments?"

Chen Yi was a little disappointed, thinking that he could gain something new in this world......

"Of course not, have you ever heard of Runi? This kind of writing is a product of that era, and today's magic is deduced through Runi characters! ”

Dumbledore told Chen Yi a secret that most people didn't know......

"Runi script ......." Chen Yi muttered, this kind of text he had heard of, it was a legendary ancient script, containing religious overtones, but he didn't expect that in the Harry Potter world, the runi script really existed!

"Okay, let's talk about you, which means you've been practicing for decades? And what's the deal with your looks? Dumbledore waved his hand to skip the boring topic, which he thought was good to listen to as stories, and it was over anyway.......

"Yes!" Chen Yi said unashamedly.

"As for looks...... The cultivators of my generation only seek immortality, and although I can't achieve immortality in my realm, I can still live a few hundred years longer than ordinary people. ”

Chen Yi made it up, but Dumbledore believed it. After all, even Nicolamay, who has the Philosopher's Stone, can't look old, but Chen Yi can!

"And what is your real age now?" Dumbledore asked curiously.

"16 years old!"

Chen Yi replied without thinking, don't ask about age, just 16 years old if you ask!

The corners of Dumbledore's mouth twitched, and he wanted to say something more, but when he saw Chen Yi's threatening little eyes, he chose to shut up.

"And you're coming to Hogwarts this time?"

"It's a bit boring to be in retreat for too long, come out and find something to dry up and breathe, you can give me a position in Hogwarts."

Chen Yi held the cup and said his purpose with a smile.

"You want to be a teacher?!"

Dumbledore's eyes widened, he couldn't imagine what it would be like for this killer with the blood of a dark wizard on his hands to teach his students.

Imagining the sight of Hogwarts students waving their wands all over the world to trouble the Dark Wizard, Dumbledore quickly shook his head and let the image dissipate in his mind.

"I'll let you be the vice principal, now that all classes already have teachers, you don't need to give lectures to students, just be responsible for order in the school and protect the safety of students."

"No, I'm going to be a Defence Against the Dark Arts professor!" Chen Yi said unrelentingly.

"But there are really enough people teaching now, I promise you that in the future, when no one comes to teach Defence Against the Dark Arts class, I will let you substitute for you, is that okay?"

Dumbledore had a headache and had to think of a compromise.

"Well, that's fine." Chen Yi's eyes rolled and he nodded in agreement.

If Chen Yi really doesn't have the opportunity to substitute for other courses, but Defense Against the Dark Arts class, thinking of the unreliable professors in the back, none of them can teach for a full year!

Seeing that Chen Yi agreed, Dumbledore breathed a sigh of relief, he was afraid that Chen Yi would have to substitute for him, and he would have to ask a professor to make room for him at that time......

"Then I'll call the other professors to come and get to know you......"
