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!

The last bell of the century has sounded.

The shadows are hazy, and the last demon hunter is chasing the out-of-control werewolf.

The blood moon is in the sky, and the ancient vampires are preparing to welcome the return of their ancestor.

Shrouded in fog, Little Red Riding Hood in Storybrooke is looking for the descendants of Grimm.

Wizards walked out of Hogwarts, "The damned mudbloods are usurping the glory of purebloods."

Groudon tore through the ground, "The thugs from Azkaban are on a killing spree."

Kyogre stirred the waves, "A new Dark Lord is about to ascend the throne."

Rayquaza pierced the sky, "Great Wizard King, Builder of the White Tower, Swordmaster of Gryffindor, Paris respectfully welcomes you."

Allen touched Arceus beside him. The sixteen tablets of creation radiated eternal light. "I'm just a training master who does this out of interest."

Others travel through time, systems, points, and omniscience.

Lin Xia travels through time and turns into Myrtle at the beginning.

In addition to the unbreakable confinement, the ghost is eyeing her covetously, and there is also a two-soul body snatching will. What kind of sky-shattering start is this? ?

Lin Xia: Okay, okay, this is how you want to play it, right?

She holds the scales of fate, reverses the strength and weakness, and sacrifices the basilisk!

After finally glimpsing a glimpse of the secret, Lin Xia reincarnates again and finds that a stupid soul splitter in Hogwarts always brings her many surprises.

Gryffindor's body forging method, Ravenclaw's soul forging method, Slytherin's soul tempering method, Hufflepuff's fishing method, the ancient twenty-eight holy clans...

Lin Xia, coming from the end of the world, holds the scales of fate high, steals the secrets in the shadows, and finally holds the power of the gods!

Nietzsche John Holmes, a child who was forcibly adopted by the Watsons during a mission, began his crazy HP magic journey from this moment on.

Hermione Granger: "You shouldn't hit your classmates, Mr. Right!"

Nietzsche Holmes: "Become a superman who resists the strong, Miss Obedient~"

He will have a series of titles in the future - the third generation of the Dark Lord, Superman, the secret lover of the Minister of Magic... (Sorry, it seems that some incredible things have been mixed in)

But the first difficulty facing him is:

Sherlock Holmes, who looks like Iron Man, and Professor Snape have started to be venomous to each other again! !

[Crossing over + becoming a cat + pseudo-antithesis + single CP Hermione + warm daily life]

Original title: "The Secret Black Cat of Hogwarts". The protagonist is not a saint, and the IQ of all the characters is basically online.

The Oriental Black Cat brought mysterious power into Hogwarts. There are so many ghosts in the school, I really want to eat one, the Dementors taste very good, Voldemort is the main meal, there is no escape!

Centaur: The end of the bear, the destroyer of herbs, the nemesis of the eight-eyed giant spider, the ominous darkness...The Mars tonight blinded my eyes.

Draco: He is a true aristocrat! What an elegance!

Simo: shepherd of lost lambs, ferryman of the sea of ​​soul, life mentor, pioneer of art.

Macon: I'm a regular little black cat.

Voldemort: Great! I am beginning to understand everything!

Harry Potter:

[Daily flow, easy, very talented in magic, from the same class as the Weasley brothers, single female protagonist (original), may be a little worse in the early stage, but will improve in the later stage, so please watch it later]

The newly appointed director, the god who traveled through time, carefully created a car accident. Our hero, after a round of roulette, arrived in the magical world.

Here he met the principal who liked wool socks

The Professor Who Turned into a Cat

A giant bat who loves making potions

Twins who like to play pranks.

Favoring black friends from my own college

Tsundere aristocratic sister

A key keeper who loves Fantastic Beasts

etc. A series of good friends and professors

Learn magic here and live a peaceful life

But some vengeance still needs to be avenged.

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.

(Contains secondary settings, rational discussion)

"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.

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?

Ivy traveled through the world of Hogwarts and became Snape's blood relative. When she was worried, she awakened the diary-making system.

I was a screenwriter in my previous life, and I write a diary in this life.

The melodramatic screenwriter Ivy integrated the original work and tailored a diary for himself.

Hogwarts has changed since then.

Hermione: What? Ivy was almost eaten by a troll because of me?

Luna: What? Ivy was almost beaten to death by bullies because of me?

Fleur: What? Ivy was nearly killed by Barty Crouch because of me?

Gabrielle: ...

Pansy: ...

When Bellatrix also began to scream, someone finally realized that something was wrong.

This guy Ivy, how many girls has he helped?
