"Come with me."

"I'll be your teacher before you enter Hogwarts, introducing you to the vibrant wizarding world and all sorts of wizards."

"I'll teach you everything I know: potions, spells, transfiguration, even the Dark Arts."

"And if one day you grow up to be a truly great savior, then point your wand at me."

"Use all the methods I've taught you, use all you have, and kill me!"

"Do you have the guts?"

"Lily Evans and James Potter's son—"

"Harry Pott!"

In a narrow alley drenched in rain,

Severus Snape, with smooth, fresh, non-greasy black hair, holding a black umbrella, reached out his hand to the nine-year-old savior of the wizarding world, who sat on the ground, his face filled with fear and bewilderment.

On the night when the savior of the wizarding world should have been born, Harry Potter died under the unforgivable curse.

The man who made almost all British wizards dare not call him by name, regained the wisdom and ambition that belonged to him from the Horcrux.

Darkness has completely enveloped the island of Great Britain.

Wizards are divided into high and low according to their bloodlines. Pure blood firmly holds the authority that belongs to the superior, and people called mudbloods can only be as humble as mud and trampled on throughout their lives.

The Ministry of Magic, which is supposed to enforce justice, is full of villains, and the castle, which is supposed to impart knowledge, is full of oppression.

In these dark times.

Jon Green, who came from across time, was brought into the exiled carriage that truly inherited the title of “Hogwarts”…

There are already two million-word finished high-quality old books, quality assurance, welcome to enter the pit!

“Happy education is not desirable.”

“As long as it is learning, it must be boring.”

“In the future, they will thank themselves for their hard work now.”

“We will add morning and evening self-study for students in grades three to six, and supervise them to practice mantra recitation and dictate mantra theory every day.”

“Even wizards must ensure that they have qualified physical fitness. Inter-get out of class exercises should be added after the second class every morning.”

“The school holds only one Quidditch competition every year. It’s too simple. We should add track and field games once a year.”

“Barabara…”

“…”

The spiritual leader of the new era wizards, the professional wizard advocates, the founder of the wizarding union, the pioneer of magic civilization, the changer, the destroyer, the sickle bearer, the blood relative of the demon king, the first president of the Hogwarts reorganization student union… Lin En Bellock persuaded Dumbledore with all his heart.

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”
