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."

Elements: [Extensive use of internet memes] [Highly charismatic paladin] [Semi-invincible build] [Pseudo-D&D setting (primarily based on the game's world view)]

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

[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:

On that day that year, the savior Harry Potter wore women's clothes and rode a dragon into the sky.

On that day that year, Dumbledore, the headmaster of Hogwarts, lost his phoenix completely.

On that day, Voldemort, a disabled man without a nose, suddenly had seven more heads.

That year and that day...

------

George Weasley: "I hit Voldemort on the head with shit!"

Fred Weasley: "I've proven it's real, I've smashed it myself!"

------

Kreiner looked up at the sky and muttered, "This isn't Harry Potter at all!"

"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."

John Shafiq, son of a nun.

As a special wizard who can devour magic power.

From the day he gained power, he knew that the world was full of greed and malice towards him.

For him, Hogwarts was the only refuge in this world.

But the fledglings always have a time to spread their wings.

Even a dormant dragon will eventually rise from the abyss.

When that day comes, what will the appearance of the dragon leaping out of the deep pool be?

[Voldemort, why does your magic taste so bad? ]

PS: The protagonist is a human, not a dragon. Dragon is just a title.

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!

There's a legend circulating around Hogwarts: Miss Lacus's first cry gave birth to the Dementors; Miss Lacus's first nightmare gave birth to the Obscurus; Miss Lacus's first fear gave birth to the Boggart; Miss Lacus's first laugh gave birth to Peeves; and Miss Lacus's light side became Voldemort! "Hogwarts, that's all a lie!" Miss Lacus protests. "Your light has no dark, heavy secrets, only light and bright!" (A playful Hogwarts fanfiction, featuring many meme elements and some Hogwarts Legacy content. The protagonist is a lone wolf, not for women.)

The era in which Harry Potter's parents lived in the Harry Potter series is called the parent generation.

The main characters include: James Potter, Sirius Black, Remus Lupin, Peter Pettigrew, Lily Evans, Severus Snape, etc.

After the popular science, here is the introduction.

1971.

The ignorant little wizards happily boarded the train to Hogwarts.

The Death Eaters developed silently in the dark, and no one knew whether the people around them were enemies or friends.

Voldemort's power will soon reach its peak, and Hogwarts will become the only truly safe place in the British wizarding world.

But there is no savior favored by fate here, only an incompetent Ministry of Magic and endless crises that are emerging more and more.

The dark ages are coming.
