[Non-time travel text, no system]

Dumbledore always thought that Voldemort was the biggest threat to the wizarding world, until a vampire who had lived for more than a thousand years came to his door with the title deed to Hogwarts——

"A thousand years have passed, and the lease of Hogwarts is up!" Dracula said, "Mr. Principal, you don't want the students to be displaced, right?"

"What do you want?" Dumbledore asked solemnly.

"Anything interesting."

"This is easy to handle. I think the Defense Against the Dark Arts professor position is quite interesting!"

…

As a result, Hogwarts has an unattended professor.

McGonagall: "Albus, I don't think Professor Dracula's teachings are suitable for poor children!"

Dumbledore: "I have no choice, no one can fire him."

…

Draco: "My father is the school director, I will definitely let him expel you!"

Lucius slapped Draco on the head, "Mr. Dracula, Draco is childish, you must not expel the school board!"

…

This is the story of a vampire who has lived too long and is so bored that he can only find fun in the magical world.

Ash Black traveled through time

Good news: The place of travel is Hogwarts

Bad news: Harry Potter is still a hundred years away

Traveling to the end of the 19th century when "Hogwarts Legacy" took place, relying on his complete knowledge of the plot and a little help from the game system, Ash Black defeated the final boss Lanlock in advance, and used Lanlock as a sample to conduct a 'safety Harmless' study of ancient magic.

However, an out-of-control experiment led to the biggest disaster in Hogwarts history, and Ash Black came to the world a hundred years later...

Good news: sleep until 1991

Bad news: Halle is a girl

Good news: Ash is a male Veela

Good news: Male Veela can enter the female dormitory!

Good news: Male Veela are not responsible!

Good news: It’s all good news!

In the summer of 1992, news that Hogwarts was about to open a new course and needed a new professor quickly spread throughout the wizarding world through newspapers such as the Daily Prophet and The Quibbler. Countless people moved and sent letters to Hogwarts.

Ciaran Frémont, as a wizard who has graduated from Hogwarts for eight years, also wants to return to Hogwarts and hold a professorship, and he also received a reply from Principal Dumbledore, inviting him for a few days Later, he went to Hogwarts for an interview. While happy, Xia Ran found that he had an urgent task. He had to submit his resignation to his immediate boss, the Director of the Department of Magical Law Enforcement, the largest department of the Ministry of Magic!

"Hello, strange wizard, what is your name?"

"Avada Kedavra."

"Fuck! What are you doing?!"

"...I will call Avada Kedavra, Avada Kendavia."

"...Who gave you this bad name?"

"I heard it's the Department of Mysteries."

"You have a grudge against the Ministry of Magic?"

"No, they don't dare."

"...Then what should I call you? You can't just recite the killing curse when we meet, right?"

"You can call me: the leader of the technological explosion in the wizarding world, the pioneer of Muggle exploration of magic, the ruler of the Hufflepuff kitchen, the ducklord, the younofull..."

Three years after graduating from Hogwarts, Felix walked into this magic school again, only this time, he was a professor!

What kind of sparks will collide with the combination of Muggle wisdom and magic?

Sherlock Forrest, who had just crossed into the world of Harry Potter, did not have a golden finger and did not inherit the memory of the original owner, looked at the Hogwarts letter of appointment in his hand, and pouted.

“Just a Defence Against the Dark Arts professor.”

…

A few years later, the Daily Prophet conducted an interview with Harry Potter, one of the ten outstanding talents in the wizarding world of the 21st century.

“When was the happiest day of your life?”

There was an uncontrollable smile on Harry’s face.

“It’s the day after Professor Forrest cursed me that I would be taken away by You-Know-Who tomorrow.”

“Uh…what about the day you least want to go through?”

Harry suddenly turned gloomy.

“Every Christmas.”

“Why is this?”

He covered his face in pain, and even couldn’t help sobbing.

“Woooooo…because on that day, Professor Forrest will wish me a Merry Christmas!”

……

The book is also known as “Please Shut Up, Professor Forrest! “, “On the matter of defeating the Dark Lord, it only takes a certain professor to open his mouth”, “I’m living a life of stealth at Hogwarts, just to live a healthy and happy life”
