"Dumbledore, hasn’t he already graduated? Why is he back at school?"

"Oh, Severus, don’t be so nervous. He’s the new Defense Against the Dark Arts professor!"

"Damn it! If I catch him using a cauldron to cook hot pot at school again, I swear I’ll duel him!"

...

"You are the worst class I have ever taught!"

"But, Professor… isn’t this your first class?"

...

"Miss Granger, as the study committee leader, you’ll guide everyone to read by the Black Lake every morning."

"Mr. Potter, as the sports committee leader, after reading, take them for a run around the Black Lake!"

...

"The countdown to the O.W.L. exams is 100 days!"

"Break the cauldrons, sink the boats—fight for full marks on the O.W.L.s!"

Douglas Holmes, a Hufflepuff with an Eastern soul, returns to Hogwarts three years after graduation to apply for a teaching position—

and brings a whole new style to the school.

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?

PS1. Teaching ancient magic texts;

PS2. Timeline, three elementary school and second grade;

John Shafiq, son of a nun.

As a special wizard who can devour magic power.

From the day he gained power, he knew that the world was full of greed and malice towards him.

For him, Hogwarts was the only refuge in this world.

But the fledglings always have a time to spread their wings.

Even a dormant dragon will eventually rise from the abyss.

When that day comes, what will the appearance of the dragon leaping out of the deep pool be?

[Voldemort, why does your magic taste so bad? ]

PS: The protagonist is a human, not a dragon. Dragon is just a title.

A product of forbidden magic, heir to the Black and White Lords. A powerful body forged from three bloodlines, a brand new soul transcending time. The magical world is in turmoil, as two generations of Dark Lords clash on the same stage, wondering who will reign supreme.

Dumbledore said, "I am your father."

Grindelwald said, "Bullshit, he's obviously closer to me."

Voldemort said, "You are the boss, I accept your position and I won't fight you anymore."

Everything is in Hogwarts: The Forbidden Son of the Black and White Demon King.

He was at Hogwarts, and had just become a Half-Blood Prince.

[Parent-generation; multiple female protagonists; no system]

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

【Funny + System + Time Travel】

Traveling through the world of Harry Potter, Howl Weasley awakened the "氪金" system. As long as he had Galleons, he could continue to become stronger.

Others rely on hard work to study, but Hall relies on Galleon.

Others rely on their understanding to learn, but Hall relies on Galleon.

Others rely on talent to learn, but Hall relies on Galleon!

As long as you are willing to pay, you can destroy Malfoy, Black, and Lestrange.

As long as the money is paid, even Dumbledore can kill him.

Since then, the reputation of a "money-making madman" has quietly risen in Hogwarts.

Mysterious man: "I heard you are very powerful in magic, kill someone for me."

Hall: "One hundred Galleons."

Mysterious Man: "Here... help me kill Voldemort."

Hall: "Who?"

Mysterious man: "Are you scared?"

Hall: "You have misunderstood. That is the last bloodline of Slytherin, the great leader of the Death Eaters, the legendary Dark Lord, and the undead with seven clones!"

"This money is not enough..."

[Single female protagonist Hermione + mainly based on the movie plot, later plot changes + system]

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

- - - - - - - - - - - - - -

Snape: Kevin? Humph! Just a cocky brat with a bit of talent.

Dumbledore: Kevin is such a good boy who would go to great lengths to help his friends.

Voldemort: Kevin, this unethical and despicable villain! He has attacked me with a crowbar every time I die!

Are you afraid of firearms that can shoot magic? What? You're not scared of those little squirt guns that only shoot "Aguamenti" and take three minutes to reload after one use? Oh, my dear customer, I'm not talking about those children's toys. I'm talking about the new big toys only big kids can use!

Please look this way:

Expelliarmus Colt! Its immense power guarantees equality for all; even Voldemort would drop his wand if hit!

Stupefy Gatling! Three thousand six hundred rounds per breath—no one can stand for more than a second under its firing muzzle!

Confringo Remington! Even Gringotts' vault door can be blown open with a single shot!

Many years later, Rita Skeeter, who had become the editor-in-chief of the Daily Prophet, asked: "When you decided to study at Hogwarts, did you foresee that you would be successful at Hogwarts?"

Mr. Andy Hall, then Minister of Magic, President of the International Confederation of Wizards, Chief Wizard of the Wizengamot, and holder of the Order of Merlin, First Class, replied helplessly: "?"

"At the time I didn't know a single spell, and I didn't even know I was a wizard."

Rita Skeeter: "So how did you learn magic?"

Andy: "You guys didn't [beep]?"

[Single female protagonist Hermione + no system + starting from the prisoner of Azkaban + mainly movies]

My name is John Merrick. In my previous life, in order to save someone, I faced the Hundred Ton King, and ended up traveling to England in the late 20th century.

Because I didn't have a system, I thought this was just an ordinary world.

But when I was 10 years old, I saw with my own eyes a car flying across the sky, and then two people who claimed to be from the Ministry of Magic came to my door. From then on, a fantasy magical world opened its doors to me.

Harry: The sky is falling, my family. A Ravenclaw actually got the recognition of the Sword of Gryffindor?

Hermione: I never thought there would be people more reckless than Harry and Ron...

Ron: I don't know, as soon as he comes, Hermione won't play with me.
