Have you ever seen someone learn magic with a rolling pin? Well, today you saw it!

Ollivander: Don't worry, kiddo. This half-finished product may look like a rolling pin, but it can actually roll noodles! Oh no, it's actually a magic wand!

A lightning-struck mahogany wand with a lightning core! Not only is it incredibly powerful, it also comes with cool special effects! Brave youngsters, take it and create miracles!

This is a story about a wealthy man who went to Hogwarts to invent things, a story about a guy who did not play by the rules and led three little ones astray, and a story about a man who single-handedly changed (or brought disaster to) the wizarding world!

The protagonist loves making staffs, loves oriental magic, and loves modifying props! He loves self-destructing magic tools, loves elixirs of immortality, and loves exploring the galaxy even more!

(The magic wand is the main plug-in. It was temporarily restricted in the early stage in order to activate more plug-ins! If you don't like it, please don't criticize. While making inventions, the original plot is interspersed. If you don't like the main storyline of the three little ones, please turn away.)

[The unknown diary of a white devil]

"In 1991, I entered school, and together with the savior Harry Potter, the magic world gave me a good feeling. Magic is really wonderful.

"In 1992, I was a little bored today, so I just went out and killed a few Death Eaters for fun."

"In 1993, Dumbledore is really old and confused. How can people feel at ease if he doesn't hold power in his own hands? No wonder he is always disgusted by the people in the Ministry of Magic."

"In 1994, why is Voldemort so timid? He has been resurrected for a long time but there is no movement. Is he still the dark devil who doesn't take all wizards seriously?"

"In 1995, why did Grindelwald come out? Two generations of dark devils joined forces? Do you still have shame?"

"In 1996, he finally stopped hiding? Just right, solved it all at once. ”

......

Hermione: Harry! You must tell Dumbledore about this - well, you can tell Damon too.

Harry: Damon, thank you, you are the only one who always believes in me - what? You want to take a photo of me in women's clothing and send it to Snape - but - why?

Professor McGonagall: It is a loss for the entire British wizarding world that you don't participate in Quidditch!

Dumbledore: Damon, I think you are right, I made a mistake - I forgot the feelings of young people - but fortunately you are here, it seems that I can be a teacher with peace of mind, after all, this is the best for me.

Death Eater: Do you think Damon White has become more and more cruel recently? I really regret being infected with the Dark Mark...

Traveling through the world of Harry Potter, Lucien awakened the loan magic system. With a flick of his hand, he could advance his rewards!

Of course, debts still have to be repaid.

So, the students at Hogwarts got to know a new student who was not only better than you, but also more competitive than you.

[Congratulations to the host for obtaining "Loki's Faceless", please repay the loan: Perfectly master the art of transformation]

Dumbledore: "With talent and hard work, could it be that Lucien is the future of the wizarding world? But the prophecy..."

[Congratulations to the host for obtaining the "Dark Magic Encyclopedia". Please repay the loan: Voldemort's head]

Voldemort: "What do you mean you owe a debt and need to borrow my head?"

[Congratulations to the host for obtaining the "Resurrection Potion Formula". Please repay the loan: create fifty new potions.]

Snape: "Lucian has developed the formula for the resurrection potion? Lily... tell Dumbledore I'm resigning as Potions Professor? Go find Lucian!"

…

Lucien put his hands behind his back and said, "I didn't expect to be this good. I just took out too many loans."

He traveled to the world of Harry Potter and became Ron Weasley, awakening to an extraordinary level of enlightenment, which brought a bit of a shock to the magical world.

"Your comprehension is extraordinary. By visualizing the starry sky, you learned the Star Sword Technique, and with one strike, you can freeze fourteen continents."

"Your comprehension is extraordinary. By breathing while asleep, you've learned the Great Dream Breathing Technique. You can practice it while you sleep."

"You have an incredible comprehension. By observing, you learned the Animagus transformation and mastered the Seventy-Two Earthly Demon Transformations."

"Your comprehension is extraordinary. Through practicing the flying broomstick, you can fly with a sword and take heads from thousands of miles away."

Ron single-handedly killed the dragon, and Harry Potter said: "And my friend, you are the real savior."

Seeing Ron master all the spells, Hermione Granger said: "Genius is just the starting point for you."

Ron destroyed the city and split the sky with one sword. Dumbledore said: "My boy, you have shown me what real magic is."

Ron imprisoned Voldemort in the Horcrux, and Voldemort said: "I wish I had never been born."

Ron chuckled: "When I'm not practicing, you see me as the bright moon in the sky. When I'm practicing, you see me as a mayfly seeing the world!"

The Hogwarts High Inquisitor's Order prohibits any professor from providing students with violent, morbid, or information that cannot be explained by magic. Any professor is prohibited from teaching students how to commit crimes in disguise by setting up crime-solving and decryption sessions in class. The above regulations are in accordance with Article 34 of the Education Order. Signed: High Inquisitor Dolores Jane Umbridge... "Good heavens, Hermione. I think we should go tell Professor Holmes that his entire course has been defined as illegal by the Ministry of Magic..." "Yes, Ron. But you probably can't find him now, because he just took Harry to the Chamber of Secrets." "The Chamber of Secrets? What is he doing there?" "Little things like stabbing himself with the fangs of basilisk and wipping the basilisk's corpse!"

[Single female protagonist Hermione + no system + starting from the prisoner of Azkaban + mainly movies]

My name is John Merrick. In my previous life, in order to save someone, I faced the Hundred Ton King, and ended up traveling to England in the late 20th century.

Because I didn't have a system, I thought this was just an ordinary world.

But when I was 10 years old, I saw with my own eyes a car flying across the sky, and then two people who claimed to be from the Ministry of Magic came to my door. From then on, a fantasy magical world opened its doors to me.

Harry: The sky is falling, my family. A Ravenclaw actually got the recognition of the Sword of Gryffindor?

Hermione: I never thought there would be people more reckless than Harry and Ron...

Ron: I don't know, as soon as he comes, Hermione won't play with me.

"Extraordinary wisdom is mankind's greatest wealth. I came to Hogwarts to learn the wisdom accumulated over the years," said Blackley.

What kind of story will unfold when a new friend enters the Harry Potter story?

Dumbledore: "Oh, that little Ravenclaw kid you're talking about. He's a smart kid who's obsessed with knowledge."

Harry: "Blackley is a very reliable man, but he can be strangely persistent sometimes."

Hermione: "Merlin's lace stockings! This is the first time I've seen someone so eager to learn."

Blackley: "Knowledge is the most precious treasure in the world, and I am a goblin with an extreme greed for knowledge. So, Professor Dumbledore, can you really not explain the principle of the Killing Curse? I want to invent a counter-spell for the Killing Curse."

Dumbledore: “…”

Voldemort: "That little wizard is simply a lunatic. He actually wanted to capture me and dissect me for research! He is a lunatic!!!"

As a time traveler from the Harry Potter universe, Vilan Costa always considered himself lucky. This was because in the timeline he traveled to, the infamous Voldemort had just reached the pinnacle of his power when he was assassinated by an unknown powerful wizard. He and Harry enrolled at Hogwarts at the same time, studying together in Gryffindor House.

After several days of unsuccessful treatment, it gained a unique ability—in short, it could accurately detect tiny marks on objects...

"Professor Dumbledore, have you ever seen Hogwarts at four in the morning?" Russell said calmly. "From midnight to six o'clock, get six hours of sleep." "From six to eight o'clock, sweat it out in the Forbidden Forest, including but not limited to wrestling with trolls, practicing riding on unicorns, dodging centaurs' arrows, and so on." "From eight to six, be ready for a full day of study." "From six to ten, study late into the night in the library." "From ten to twelve, practice dueling skills in the Room of Requirement." This is the simple yet fulfilling day of Russell Fishthorne, the King of the Curriculum at Hogwarts.
