【Important reminder: This book is serious! 】

[Reminder: The title brings a smile, but there is no smile originally! ]

Traveling to the world of Harry Potter, as the youngest girl of the ancient Black family? And having a powerful magical talent?

But what if your knowledge is limited to one or two movies you watched many years ago?

Don't worry, it's just children's literature, with just a few tropes...

No, this is different from what I expected!

You say I'm the Heir of Slytherin? No, no, whoever wants to go can go. You already have magic, why are you still playing tricks on a bunch of bugs? If you have that much free time, you'd be better off studying the practical application of Hermetic Runes in the Hohenheim Model!

Connections? Wealth? Power? These things that the world considers real are but illusions. And magic, a power considered imaginary, has become the only reality!

Human power is limited, but magic is endless.

Many years later...

Wizards praise her name in their prayers, calling her the Demon King, the Lord of Wizards, the Apostle of Arrogance, the Dominating Witch, the Man closest to God and the God closest to Man.

The unlucky ones were moved to tears by the kryptonian gold card draw. Zuo Yu could never have imagined that the consequence of a huge guaranteed draw would result in his soul being transported to the world of "Genshin Impact" before the plot even began!

Luckily, it's linked to a system, and the newbie gift pack includes Harry Potter magic? When "Expelliarmus" actually disarms the Hilichurl's club, and when the energetic Amber descends from the sky to save the onlookers, Zuo Yu realizes: Is there something wrong with this style?

With one hand casting Hogwarts spells and the other waiting to "send equipment" to his Teyvat companions, the Genshin Impact account decided to set a small goal first - follow Amber and arrive safely in Mondstadt!

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)

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!

(Upgrade flow, modern mystery, behind-the-scenes flow, no CP)

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)

Traveling to the world of Harry Potter, Ivan Vesemir became the heir of a pure-blood family.

Adhering to the central idea of "If you can survive, you will survive", Ivan handed over the Horcrux he got to Dumbledore, detoured when he met Harry Potter on the road, lowered his grades in the exam to make the professor ignore him, take a step back and find a way out;

Arm yourself with alchemy, study black magic and learn about your enemies.

And then, he was inexplicably targeted by the boss...

"What? Why can I achieve what I am today? Ah... It's embarrassing to say, they won't let me go on, so I can only find a way to kill them all."

Hogwarts Honorary Headmaster, Eagle of Helheim, Incarnate Man, Midas Toucher, Enemy of Goblins, First Class Merlin Medal Winner, Honeydukes Candy Shop Owner——Ivan Vesemir Said.

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?

First, Dumbledore knew that Gilderoy Lockhart was a fake.

Secondly, Lockhart also knew that Lockhart was a fake because he traveled through time and space and became Lockhart.

The problem now is that Dumbledore plans to invite him to Hogwarts as a negative example, while Lockhart, a fake who can't even perform the simplest magic, just wants to lie down and enjoy the wealth accumulated by his original body.

But in the end, Lockhart still went to Hogwarts to serve as a professor of Defense Against the Dark Arts.

Wasn't the magic mansion and the vault full of gold galleons attractive?

Or was it that the achievement of more than a dozen best-selling books that earned him endless royalties was not enough to satisfy him?

Or were Snape and Voldemort, who were obsessed with their own positions, not scary?

No, neither of them. It's because Lockhart was forced to go to school by Dumbledore! So... find a way to make this year's mission...

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