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!

Reporter: "Excuse me, Mr. Green, people from the Ministry of Magic call you the most terrifying, evil, and powerful Dark Lord in history. What do you think?" Green: "These are slanders and slanders against me by the Ministry of Magic. They They are just jealous of my talent." Greene "I advise these officials of the Ministry of Magic to behave themselves, reflect carefully, and not to make such mistakes again in the future, to be clever, ah, uh... The magic world should value peace, practice martial ethics, and not engage in quarrels. ." Reporter: "Mr. Green, why did the Dementor...

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?

Forming a bond with a woman will earn you rewards; forming a bond with a noble woman will earn you even more rewards.

Having experienced two consecutive time travels, Li Zhihui finally awakened his system, but he ended up with an unorthodox one.

"So, it's really not that I'm promiscuous, it's just something that can't be helped."

The following worlds have been confirmed: Baldur's Gate, The Witcher, Cyberpunk 2077, and Hogwarts.

"What is the most valuable asset of Ravenclaw?"

"Wisdom."

"Then where does wisdom go?"

"Any direction, as long as we want, we can always find like-minded people in the house. Companions are our second wealth."

"Very good, that's it, we are united because we have the same aspirations. So, what is the most important thing besides that?"

"Of course, it is to send some of the other Ravenclaws to Azkaban."

"Absolutely right - this is how we Ravenclaws are."

On the night when the savior of the wizarding world should have been born, Harry Potter died under the unforgivable curse.

The man who made almost all British wizards dare not call him by name, regained the wisdom and ambition that belonged to him from the Horcrux.

Darkness has completely enveloped the island of Great Britain.

Wizards are divided into high and low according to their bloodlines. Pure blood firmly holds the authority that belongs to the superior, and people called mudbloods can only be as humble as mud and trampled on throughout their lives.

The Ministry of Magic, which is supposed to enforce justice, is full of villains, and the castle, which is supposed to impart knowledge, is full of oppression.

In these dark times.

Jon Green, who came from across time, was brought into the exiled carriage that truly inherited the title of “Hogwarts”…

There are already two million-word finished high-quality old books, quality assurance, welcome to enter the pit!

(Otome + multiple male protagonists + sweet love + separate endings + parent generation + child generation) Lina, a male health expert, traveled through time to the magical world of Harry Potter and became Selina Lestrange, a therapist at St. Mungo's. She was also a crazy fan of Sirius Black. She took advantage of her position to go to Azkaban every day, but it was hard for her to "deepen her roots" in a field she was not good at.

See how she shakes off the label of "star chaser" and "rebuilds her reputation" at St. Mungo's! And wins everyone's love (mistake)!

Sirius: That woman has changed! How come she's still... pretty?

Snape: I don't have that disease, thank you!

Lucius: I heard that you can help me give birth to a daughter?

Bill: Thank you for your care every time

Barty Jr.: You saved me, my life is yours...

Please look forward to more male protagonists——

(Sirius chases his wife to the crematorium ➕ all members survive ➕ private settings like mountains, focusing on otome literature for a hundred years, the official pairing may be broken, if you don't like it, please don't enter)

[Single female protagonist Hermione (yandere version), invincible, daily, only the Harry Potter world, a lot of personal settings.]

[I'm really a yandere, I don't like it if you mistakenly enter. I really can't write a description, so let's leave it at that.]

Humans are the protagonists of this world. They will never know their own potential, let alone what kind of existence they can give birth to.

When humans created the word fear, fear took on a physical form...

Draco: Red hair, second-hand robes, second-hand textbooks, I know who you are, another Weasley. Penelope: Your sister? Jordan: Your sister? McGonagall: Your sister? Claire: Oo? Your sister! Ginny blushed: Hello, sister. Percy: Merlin, I want to write a letter to mom... no... to dad! Fred said to George: Is this our sister that dad lost? George's eyes lit up: There will be 6 Weasleys in this school! Sorting Hat: Another Weasley? Gryffindor! Claire: Occasionally look up at the sky, the sun rises and the sky turns red. Fred: A Weasley marries a Weasley and doesn't even have to change her last name.
