As a survivor of the war, Roger is learning magic just to survive.

Nicolas Flamel: "Then I will teach you how to make the Philosopher's Stone and brew the Elixir of Life, okay?"

"No, no, it's called immortality, but after hundreds of years, the body will decay and suffer endlessly. Can this be called immortality?" Roger shook his head.

Voldemort: "I will teach you the method of Horcruxes, which can be divided into seven parts and reborn after death. How about it?"

"If you don't want to learn, you will be incomplete if your soul is cut. Even if you seem to be reborn, the Ship of Theseus, which has lost its continuity, is no longer the me I once was?"

Dumbledore: "Death is not the end, but a new great adventure. I will teach you..."

Before he finished speaking, Roger interrupted: "When there is still hope, choosing death is nothing more than admitting defeat and escaping from this world. Without hope, how is it different from real death? Don't learn!"

Grindelwald: "I will teach you the art of prophecy, anticipate the enemy's moves, grasp the tide of the times, lead wizards to greatness again, and then gather the power of all wizards to support you and prolong your life. How about it?"

Roger, who is also a prophet like him, thought about it seriously, and finally shook his head. "Just as I am now above this era, there are always talented people in every generation, and the world is vast and boundless. No matter how powerful I am, there will always be more powerful beings standing in front of me in the future. No one is always invincible, and no one is really invincible. Being too deeply involved with all living beings is not the way to eternity."

Rejecting the teachings of the last elder, Roger Virgil looked into the starry sky: "...There is no way in the world, it seems that I can only open one myself."

Edward Bedwell, who traveled to the wizarding world of Hogwarts, found himself a descendant of one of the Arthurian Knights of the Round Table. Not only that, but as long as he abides by the knightly virtues, he can gain the corresponding power. Humility and restraint allow him to be absolutely focused. Treating people with sincerity allows him to distinguish between truth and falsehood. The Weak can make him perceive all things. ...... Following the ancient knightly virtues, inheriting the will of his ancestors, studying the "Handbook of Magical Knights", Edward, who entered Hogwarts to study, practiced his own knighthood at all times. He was humble, sincere, and compassionate, and was well liked by his teachers and classmates. He was fearless, unafraid, and impartial, and the dark wizards were feared in front of him. He changed Slytherin and changed Hogwarts

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!

Will Evans wakes up to find himself transported to the world of Harry Potter. Good news: he knows the entire plot. Bad news: he knows nothing but the original story. So, Will decides—to cling to Dumbledore's coattails and achieve a life of effortless success! "Professor, Quirrell has a face on the back of his head!" "Professor, the diary has a mind of its own, burn it with Fiendfyre!" "Professor, don't wear that ring, it'll kill people!" Dumbledore: ...?

The false devil:

Gather the Saints to fight against the Muggles.

Occupy Britain and attack the school.

The real devil:

Destroy the world and cause great suffering to all living beings.

Elias traveled through time for eleven years and suddenly found out that he had traveled to the world of Harry Potter and was chosen by the bloodline of the devil!

You only need to gather three of the seven deadly sins: pride, wrath, laziness, greed, envy, gluttony, and ecstasy, and the power of the devil in your blood will automatically summon the devil to possess you and destroy the world!

For the peace of the world,

From that day on, Elias knew that his idle life would be gone forever...

In the magic world a thousand years ago, he traveled with four teachers for seven years. Ryan found himself back in 1991, back to the orphanage he was familiar with. After three days. He saw a pure white owl flying towards him with a Hogwarts admission letter in its beak. So Ryan knew that he would return to the Hogwarts that was familiar yet unfamiliar to him. "Mr. Ryan Elias." "Dumbledore called you the most outstanding graduate in the history of Hogwarts, the Dark Lord regarded you as his greatest enemy, and the dark wizards called you a wizard destined to be great. For these titles..." "Of course." Ryan answered calmly with the answer that should be given. "I approve of it all." Be it potions, duels, spells, alchemy, the dark arts, or even cooking and pranks. "Of course I will always be the best." Because he...

*"Avada Kedavra!"*

The evil Dark Wizard cast the Unforgivable Curse.

Yet Asher, unfazed by danger, even laughed and taunted:

*"Come on! Kill me if you have the guts!"*

Then, the eerie green light struck Asher’s body—

but the one who dropped dead was the Dark Wizard himself.

*"Heh… Didn’t expect that, huh?*

*There are people under us!"*

Wade: I only studied at Hogwarts for seven years, which means 266 weeks excluding holidays! Even if I can finish a book in a week, 266 weeks is only 266 books! How many magic books are there in the Hogwarts library? Thousands of them! Time is running out, how can I not seize the time to study? ! I will never allow anyone to destroy my learning environment - not even the Dark Lord! No, no, no, I don't just love knowledge. I'm just greedy.

On the day he crossed the world of Harry Potter and received the admission notice, Ethan awakened the achievement system. As long as he made the corresponding events, he could get rewards.

With three million gold, he has achieved the achievement of [hegemony and wealth can rival the country].

Get the blood of magical animals and achieve the achievement [I'm not a human].

Use Avadaso's life to kill 100 wizards and achieve the achievement of [Gnawing Big Melon Lover].

......

On the day of graduation, when Ethan was seamlessly appointed Minister of Magic, the reporter of The Prophet's Daily asked:

"Mr. Adrian, as the youngest and best Minister of Magic in history, I heard that you have been famous for Hogwarts in the first year of admission, won the Merlin Order Medal in two years, and directly overturned the professor in three years... I don't know why you have achieved such dazzling results?"

Ethan Adrian spread his hands: "I really want to make progress!"

Rowling travels through the world of Harry Potter and awakens to become a necromancer.

Having escaped Azkaban twice, he is famous (and infamous) in the wizarding world.

But he was hired by Hogwarts as a professor of Defense Against the Dark Arts.

Dumbledore: "Letting Rowling become a professor at Hogwarts is the best decision I have ever made in my life. But Rowling, why are you sitting in my seat?"

Snape: "You are definitely the next Dark Lord. I will keep an eye on you. Wait, why did you expel me?"

Professor McGonagall: "Rowling, I've told you many times that Transfiguration can't turn your pile of skeletons into a catgirl!"

...

Many years later.

Some people call Rowling the greatest wizard in the wizarding world after Dumbledore.

Some people also say that Rowling has influenced the atmosphere of the magical world and is a sinner of the magical world!

Some even say that Rowling becoming the headmaster of Hogwarts is a disgrace to Hogwarts!

Rowling, surrounded by the Scourge, sat on the golden chair in the Hogwarts Great Hall, looking helpless:

"How did I, a prisoner of Azkaban, get hired as a professor at Hogwarts and eventually become the headmaster?"

"It can only be said that a person's fate..."
