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...

Traveling to England in the 1980s, Jon Hart was ready to study and work hard.

Not wanting a letter from Hogwarts, disrupting all his plans.

What is the cruelest thing for a student who is ready to devote himself to scientific research and has carefully planned for more than ten years?

That is to tell him that this world is not only unscientific, but magical!

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.

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!"

Gilderoy Lockhart has just become Minister for Magic of the United Kingdom, and there are several uninvited guests in the office.

Dumbledore: “Minister, I have to tell you with great sadness that Moriarty Slytherin is the most hidden person in the European wizarding world!”

Lovegood, editor-in-chief of The Quibbler: “Look Minister, the Hogwarts Riots, the Himalayan Avalanche, the Gringotts Heist, the World Cup Opening, the Nurmengard Bombing, the Azkaban Defection , the Durmstrang riot, these mysteries all point to one person, Moriarty Slytherin!”

Platinum noble Lucius: “On behalf of the pure blood family, I strongly request the minister to launch a wanted request for Moriarty Slytherin! Oh, my minister, don’t look at me with greedy eyes, all pure blood money is taken by Mori Artie’s gone.”

Gilderoy Lockhart showed his signature smile: “Please allow me to introduce to you my young master, the greatest wizard of all time, the master of dawn and darkness, the master of ice and thunder, the legendary god of magic, Moriarty Slytherin!”

This is the story of a little wizard who only has magic in his heart and becomes the big boss behind the scenes in the Harry Potter world.

Ever since he lost his beloved pet Nagini, Mr. Voldemort felt that everything was going wrong for him. Looking at the servants kneeling on the ground and crying, the Great Demon roared in his heart that he would make the bastard who stole his pet pay with his life.

A thief who was flirting with Furong and laughing at Zhang Qiu's disastrous defeat in the Quidditch match yawned repeatedly: "Which bastard cursed me behind my back!"

PS: This article is a general logic article. The protagonist relies on the Eastern practice system to surpass Voldemort. Otherwise, even if Hermione is talented, she will be beaten by the Death Eaters. Through planning and cultivating your own power, you will start to grow in the middle stage and dominate the world in the later stage.

Browder of the third generation was reborn in the world of Harry Potter.

The legacy of the previous two lives gave Browder a stronger foundation in this life.

But… the water in Harry Potter’s world is really deep!

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...

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.

Travel through the world of Harry Potter and obtain the [Positive Energy Explosion Attribute System].

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"
