After traveling through the Harry Potter world for seventeen years, Whitefall, who could only use dark magic, was expelled from Hogwarts and became a Death Eater. He was later imprisoned in Azkaban for helping Voldemort.

With no other options left, he took out his wand and was about to commit suicide.

As he was about to die, he heard a golden light explode in his head.

[Ding, your Infinite Forbidden Spell System has been bound.]

No, I was already in Azkaban, and Goldfinger only came?

When he woke up again, he had returned to the scene seven years ago.

At that time, he had not yet entered Hogwarts and was surviving in the cracks of an orphanage.

With the help of the system, Bai Yun uses power far beyond black magic to reach the pinnacle of magic.

If he were to live his life over again, he would make the entire magical world submit to him!

"Auror? What does your arrest of dark wizards have to do with me, the Forbidden Spells Master?"

"Death Eaters? Do you think a mere Voldemort is worthy of my submission?"

"Defense Against the Dark Arts? Sorry, I was instantly killed by a forbidden spell!"

In this life, Bai Yun officially opens a new era of the magical world with his memory and golden finger!

Harry: It seems my classmates are more dangerous than Voldemort?

Dumbledore: Our house has opened Azkaban?

Voldemort: You are using my words!

Edward traveled through time again and came to a mysterious world.

From then on, there was a stranger here who could travel between the two worlds regularly.

So, what will he bring to both worlds?

ps2: The path of the protagonist of this book is semi-original. He takes the path of [Apprentice] in the early stage and starts to change in the middle stage.

ps3: The protagonist is basically invincible in the same level, but he can't kill high-sequence enemies.

"Albus Dumbledore made two great mistakes in his life: one was Tom Riddle, and the other was Jim Lynch." Jim Lynch, the "Mist Hangman," a forbidden legend who hunted hundreds of dark wizards, was locked in the Forbidden Forest by Dumbledore himself. When the savior Harry enrolled in school, he tore open his cage and returned to the wizarding world as a professor. Dumbledore regarded him as a hidden danger, and the Ministry of Magic became his chess game, with death walking with him. When the sky of Hogwarts was set on fire, Lynch stepped out of the fire and smiled elegantly at Voldemort: "Hello, Tom, did you miss me?"

Every time you travel through a new world, you become a strange character or even a non-character.

Talking Tom, Knight, Witch, Slime, Snow King...

Ding Hai was also forced to start a wandering life in the heavens and all realms.

When he turned into Tom Cat, he received an invitation letter to Hogwarts School.

Then, the adventure of the fun people began...

As a titan, Cabela is undoubtedly unique.

A unique body that can shrink and transform into a humanoid form

Unique timidity

When Godzilla and Ghidorah fought and destroyed her home

She: Waving her hands in protest! The two bosses probably didn't see it, so run away! Find another place to settle down

Until she learned magic (her smile gradually widened) My fellow humans, it makes sense for me to fight with magic~

As a magic school, Hogwarts certainly never thought that it would admit a monster.

Professor McGonagall: I think it is embarrassing for me to take this new student.

Dumbledore: How could that be? The child is... 20,000 Leagues Under the Sea!

As the companion of a Titan, Hermione said she was shocked that Campbell could be so soft and timid.

Canberra: Just tell me whether you like it or not!

Hermione: I love it!

(Note: This is a story with two female protagonists. The author has some knowledge about Titans, but not much. The personal settings and timeline may be a bit messy, so please don't read it too carefully. Welcome to read)

If Dumbledore had not defeated Grindelwald.

If the war between wizards and Muggles really broke out.

If the finger witch that the faded one failed to meet was reborn in the body of an 11-year-old wizard girl.

My name is Hermione Granger, and I will rebuild the magic circle of this broken world.

[HP Parent Generation + Child Generation + Daily Life + Taoism and Magic Dual Cultivation]

Lin Long is Lily's cousin. When she was ten years old, she was sent to the Evans family by her parents for refuge.

Growing up with Petunia and Lily, he also met a boy with black hair and black eyes.

But he didn't seem to like himself very much.

Later, they went to Hogwarts to study together.

At the beginning, she was a weakling in magic and could only rely on spells and talents to take Sirius and James to avoid the Death Eaters. Her talents and skills were also noticed by Dumbledore.

In the second year, he began to learn Taoism from Uncle Jiu, and started to practice both magic and Taoism.

But he faced the big boss Voldemort.

In the fifth grade, Snape had a falling out with Lily and also broke off his friendship with Lin Long.

Lin Long returned to China and officially began her path of cultivation.

When he returned to the wizarding world again, it was Harry Potter's first year.

When they met again, he stood in the forbidden forest, watching her drifting away like a mist in the wind, and then he said to himself: Long time no see.

CP Snape

Not a cool story! Not a cool story! Not a cool story!!!

(Note: Not against James! Not against Sirius! Not against Lily! Not against Dumbledore! Not against Snape! Not against everyone!)

[Cyberpunk][Harry Potter][Dual World Shuttle]

Harry Potter: Old man, the work is done, give me the money

Dumbledore: Harry, 60 points from Gryffindor for your bravery.

Harry Potter: Damn it, I almost died there, and you just give me some extra points and that’s it?

Dumbledore: ...

Malfoy: Pott, you shouldn't be hanging out with those mudbloods, the disgrace to purebloods.

Harry Potter: Go away, company dog, oh no, puppy

Priest: Harry, I have a big order that I think you can take on.

Harry Potter: Dad, don’t you always ask me to handle your big orders internally?╮(￣⊿￣)╭

V: Harry, you, want to go to Arasaka Tower with me and cause a scene?

Harry: You hit the nail on the head. Let the year 2023 bring back the past, V. Let's burn Arasaka Tower to ashes!

Mann: Harry, how are you? (He leans forward) Um, that soothing agent you have...

Harry: It's the soul... Never mind, I'll give you a 30% discount for Rebecca's sake.

Rebecca: Harry, explain why you stood me up last time, honey~ (pulling out the iron gall)

Harry: I, um, I said I traveled through time, do you believe it... Don't load the gun!

Left at his aunt's doorstep, baby Harry Potter arrived in Night City after a mishap. Raised by Father Sebastian, he became a "special" mercenary for the Valentino Gang. But after a mission, he traveled back to his original world, and a line of small words appeared on his prosthetic eye: Shuttle Energy, Accumulating...

Tibbers’ confession:

I am a shadow bear! An extremely powerful shadow bear! A shadow bear that is expected to become the king of shadow bears in the future!

I am arrogant in the shadow world! Bullying the male and the female! No one dares to oppose me! Because the bear or other creatures who opposed me are dead!

However, I never expected that I would fall into the hands of a two-year-old human girl!

It was a sunny afternoon…..Forget it, let’s not mention that day!

I was forced into a contract to become a teddy bear without bear rights! She named me Tibbers!

The one thing I want most now is: more unscrupulous creatures to provoke my master, so that I can often come out and let go…

Matthew traveled to "Harry Potter", only to find that the world was facing the invasion of various foreign evil gods:

The "Dimensional Devil" that rules purgatory, the "Eyes of the Abyss" that dominate the spirit world, the "Paradox Devourer" that occupies the void...

There is also the "Blood Lord" who stole his chance to travel through time and whose strength has undergone a qualitative change...

There are suddenly many evil cults in the world. They are the root of the old beliefs and the anchor point for the invasion of foreign gods.

Fortunately, the system has awakened an incredible wisdom!

Yes, you read that right! The system has given itself a cheat code!

And as the host...Matthew can completely skip the comprehension steps and directly obtain the results of comprehension!

What does your understanding mean to my understanding? We just have different divisions of labor.

Many years later, when many evil gods were willing to burn the world to death in order to descend upon Hogwarts:

[You have come into contact with the origin of the laws of space. Due to your extraordinary understanding, you have gained the right to manage the crystal wall of the world.]

[You watched the world that was about to fall. Due to your extraordinary understanding, you mastered the endless world destruction chain.]

You can figure out the system, and leave Hogwarts to me!

Looking at the system prompt, Matthew announced domineeringly:

Evil God, get out of my Hogwarts!

…

Dumbledore: Wait, your what?
