(Not a cool story, the main plot, don't read if you don't like it!) There are twists and turns in the early relationship, and there will be explanations in the middle and late stages. Don't read if you only like cool stories. If you come in, you don't have the patience, so why come in! Slytherin from the Muggle world, Gryffindor, who is also a childhood sweetheart from the Muggle world, and there is also a Potter beside her. Looking at the three people below, Snape fell into deep thought, are you going to kill me? This is a magical world, and the protagonist is a soul from the 21st century. How can he not know the greatness of science? Then, what kind of sparks can the combination of magic and science splash out? This is a story about a protagonist who is a little bit second-year, and is pushed to the position of the Dark Lord step by step by his good friend! The most important point is that Hermione fits the original character, and her character is not likable. If you like the kind of vase Hermione, please don't come in! ! !

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.

[I, Cassandra Malfoy.] [I am the most outstanding Slytherin, with clear ambitions!] [I am the brightest morning star of the pure-blood family, the eternal pride of Hogwarts!] [Voldemort will fall at my feet, the Ministry of Magic will bow before me, and the entire wizarding world will obey my leadership.] [To recast the glory of magic and to be supreme over all living beings, this is my ultimate goal!] "Wait, who are you? What are you talking about?" With golden curly hair and emerald eyes, the 11-year-old Cassandra listened.

As a time traveler, Agares decided to stay away from Hogwarts after graduating, fearing he'd be caught up in the dangerous situation. However, his thoughts changed after he struck a deal with Arceus, the Pokémon God. Chosen by Arceus as a Pokémon ambassador, Agares decided to start promoting Pokémon among the more receptive wizarding community. Five years after graduation, Agares returned to the magic school, this time as a professor.

Sylby Krios's childhood was filled with cold metal and endless criticism. He always wanted to escape from this home. After secretly learning the family craft, he finally received a letter to Hogwarts.

"The Days of Child Labor in the Wizarding World"

“It’s not some animal translator.”

"My roommate is the future Dark Lord"

"Magic wands know not to do things they don't like."

"The thing that is wrong with cutting is definitely not the cake"

"Is it wrong for workers to be saviors?"

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!

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?

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: ...

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.

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...

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.
