Hogwarts: I graduated before the system came

Chapter 324 Douglas leisurely watching a movie (Happy New Year)

Professor McGonagall sat in the classroom, her eyes sweeping across the noisy students, her lips gradually pursed into a straight line. Her serious expression seemed to penetrate the noisy crowd, making the air around them a little colder.

Finally, she stood up and tapped the wine glass in front of her with the wand in her hand. The crisp sound was like a wake-up call, instantly quieting the noisy auditorium.

"Given your outstanding performance at the dinner,

There was an undeniable authority in Professor McGonagall's voice.

"Each student needs to submit a report on this study tour, detailing the history, mechanisms, and potential impact of each place they visited on the current magical world. Each person must write a report at least 20 inches long and submit it to me on Monday two weeks later. Students who did not participate can communicate with those who did."

As soon as these words were spoken, there was a burst of sighs from the audience.

At this time, a senior student slowly stood up from a corner of the Slytherin table. He bowed slightly, with a polite yet slightly cunning smile on his face, and said:

"Professor, since the Slytherin students did not participate in the commotion during the dinner and maintained proper behavior, can they be exempted from this assignment?"

Professor McGonagall's gaze lingered on the Slytherin students for a moment, a subtle hint of recognition flashing in her eyes. She nodded slightly and said:

"Well, Slytherin students are exempt from this assignment."

However, Professor Snape, who was sitting next to him, snorted slightly.

He swept his gloomy eyes over the Slytherin students and said in his signature low and hoarse voice:

"Slytherin students won't slacken their pursuit of knowledge just because of this little favor. Students of this academy, go back and prepare a paper on the latest research progress in Muggle and magical potions. Also, each person should write a 30-inch paper and submit it to me in two weeks.

If you don't know how to do it, you can consult your Professor Holmes. I think he has plenty of time to explain to you the advantages and disadvantages of Muggle Potions in detail."

The smiles on the Slytherin students' faces froze instantly, and they accepted the fact helplessly.

It was only then that the students noticed that Professor Holmes and Headmaster Dumbledore had not been seen at this point in the dinner.

Ron stuffed a chicken drumstick into his mouth and mumbled:

"Hey, did you notice? Neither the headmaster nor Professor Holmes came to the dinner!"

Hermione frowned, patted Ron's arm lightly, and said angrily:

"Ron, don't be so anxious to eat. This is really strange, though."

She put down the cutlery in her hand and her expression became serious.

"Headmaster Dumbledore rarely misses school activities. Could something urgent have happened?"

Harry propped his chin up with his hands and said thoughtfully, "Maybe it has something to do with the events in Godric's Hollow today? I always feel that the atmosphere here is a little strange today, and Sirius won't tell me anything."

There was a hint of worry in his eyes and his brows were slightly furrowed. After all, that was his home now, and he planned to find an opportunity during the summer vacation to bring some friends to help him clean up his home.

At this moment, Fred and George, who were sitting next to each other, looked at each other and smiled evilly.

Fred raised an eyebrow and said loudly, "Maybe the principal and the professor are secretly developing new magic candies and are preparing a big surprise for us!"

George chimed in, "Haha, yeah, maybe next time we have class there'll be a bunch of exploding chocolate frogs falling from the ceiling!"

The two of them made exaggerated gestures as they spoke, causing the students around them to burst into laughter. Then, they caught a glimpse of Professor McGonagall's livid face and shut up in unison.

"Fred, George, stop it!" Hermione glared at them angrily, "This is not the time to joke around."

"Oh, Hermione, relax, maybe they're just going to a super secret wizarding party!"

George made a face at Hermione and continued to play with Fred.

Neville rolled up his sleeves and said, "Could there be any news about Peter who escaped?"

His voice grew louder and louder, his face lit up with excitement. If the dean hadn't specifically instructed that the Gale Sword Club wasn't allowed to bring swords to court, he would have excitedly drawn his sword...

Ginny patted Neville's shoulder and said, "Neville, don't get excited. If it really is the other party, how can it be our turn? That would be a shame for the Aurors."

"hey-hey!"

There was a sound of crickets all around. After all, they had trapped Peter last time, but when the Aurors arrived, the other party took the opportunity to escape.

Douglas' home in London.

In the spacious living room, Headmaster Dumbledore stood there quietly, his silver hair neatly tied behind his head, his long beard hanging down to his chest, and the wrinkles on his face seemed to be engraved with countless wisdom and stories.

There was a hint of fatigue in his deep eyes, but more of a desire to explore the unknown.

On the oak table in front of him were all sorts of strange and bizarre tools, some of which gleamed with the peculiar luster of Muggle technology.

His brows were furrowed, his hands kept fiddling with the parts, his eyes focused and determined, as he thought about how to connect these Muggle products with magic.

Sirius was pacing back and forth beside him, his long black hair was a little messy, he was wearing a leather jacket and a pair of black jeans, his boots made dull sounds on the wooden floor.

His eyes revealed a kind of unruly and intelligent look. From time to time, he picked up a part, looked at it carefully, and then began to explain it to Dumbledore.

Sirius picked up a small metal gear, pointed at the tooth marks on it and said:

"Headmaster, look, this is the key component that Muggles use to control the speed of film rotation. Through a sophisticated mechanical structure, it ensures that every frame of film can accurately capture the image during shooting, and that the image can be presented at the appropriate speed during playback, allowing the audience to see a coherent dynamic picture."

As he spoke, he gestured with his hands to show how the gears turned, his eyes flashing with familiarity and pride in these Muggle technologies.

Dumbledore leaned forward slightly, his eyes closely following Sirius's movements, listening carefully to his explanation, nodding slightly from time to time, a thoughtful look in his eyes.

Sirius then picked up a lens and continued, "This lens is even more amazing. By adjusting the combination and distance of the lenses, it can change the angle of refraction of light, thereby achieving focus and zoom on the subject. Muggles have used these optical principles to create countless amazing photographic works."

His voice was full of admiration for the wisdom of Muggles. Although he was a wizard, the more he learned about the Muggle world over the past year, the more he felt that Muggle technology was no simpler than alchemy.

After Sirius finished explaining in detail the principles and uses of various tools, the two fell into a brief silence.

They all turned their heads to look at Douglas, who was sitting in front of the computer, drinking tea and watching a movie.

This time, for research purposes, they bought a lot of video discs, and Douglas had to reluctantly revisit these classic old films.

Seeing the two looking at him, Douglas said quietly, "I'm just a consultant. I can't ask for a consultant right from the start, can I?"

Dumbledore rubbed his head and said, "In that case, why don't you go to the school dinner? You have nothing to do here."

Douglas blinked and said, "Because this is my home! I'm mainly worried that you might accidentally blow up my house while dismantling the Muggle props. As a consultant, I'm here to clean up any mess for you at any time."

Dumbledore (-@y@)

Sirius (ーдー)

The two looked at Dobby, who was taking notes of his work in a notebook.

Dobby said hurriedly, "Headmaster Dumbledore, Dobby doesn't know as much about this as Mr. Black."

Chapter 325 Magic Disc

Dumbledore stroked his beard leisurely, his eyes flickering with thought, and slowly said:

"After this period of research, I have a general understanding of the operating mechanism of Muggle movies. It is nothing more than quickly changing and projecting a series of images to create a kind of visual... visual..."

"It's persistence of vision, sir!" Dobby interrupted eagerly, his eyes full of a desire to show off his agility.

Dumbledore smiled amiably, nodded slightly at Dobby, and then continued to explain slowly:

“However, memory should be more accurately described as the visual representation of thought, which is itself a coherent combination of sound and image. If we break it down into scattered images and then attach them to film, we will not only miss the point but also greatly increase the burden on the production staff.

And based on my understanding of various materials, films that can attach memory substances require rare materials such as dragon skin fiber and unicorn hair, which will undoubtedly significantly increase the cost.

Let's turn our attention to the crystal ball. As a common divination tool, the crystal ball actually has the potential to be transformed into a memory retention tool.

Memory Infusion Magic can be used to infuse memory substances into specially treated crystal balls. These crystal balls contain magical liquids, such as a mixture of Veela tears and potion ingredients. This solution interacts with the memory substances, allowing the memory to be visually and audibly manifested within the crystal ball.

But it's not perfect. Its drawbacks are that the memory image can only be displayed inside or on the surface of the crystal ball, and can only be viewed by one person. Of course, most importantly, it's expensive and cumbersome to use.

After saying this, Dumbledore gently picked up the disc on the table and continued:

"Actually, I'm quite optimistic about this disc. It contains a wealth of information and can record both images and sound.

Since it can record information with the help of light, we might as well use it as the basic carrier, so that we can save our basic production costs.

The disc is further transformed with magic, and the edited memory material is then sealed in the disc's recording layer, and then played back using the appropriate tools, just like Doug watching a movie."

Sirius nodded thoughtfully, then added:

"According to my careful observation, among the many forms of information storage used by Muggles, optical discs are the only one that is not affected by magnetic fields. This means that even in an environment like Hogwarts, where magic is intertwined and magnetic fields are complex, no information will be damaged or lost."

Douglas turned around and looked at Sirius in surprise. He had originally expected Sirius to use the Marauder's Map's ingenious design and create something similar to a flat ink screen using parchment.

This would allow the wizarding world to keep pace with the Muggle world in terms of technological advancements in communication devices. (After all, the first PDA was released in 1993.)

Sirius noticed Douglas's strange look, and with a puzzled look on his face, he asked, "What's wrong? Is there something wrong with what I said?"

Douglas shook his head slightly and said with a smile:

"Nothing, it's just that your idea is a little different from my previous speculation. But you are right, optical discs do have unique advantages in stability.

However, we still need to consider how to make the storage of memories on optical discs more efficient and durable. After all, memory materials may be more complex and difficult to control than ordinary information data."

Dumbledore folded his hands, pondered for a moment, and said:

"Perhaps we can approach this from the perspective of magic circles, engraving a specific magic circle on the disc to enhance its ability to hold and preserve memory materials. Just like ancient magical artifacts, magic circles were often used to enhance their effectiveness and stability."

Douglas glanced at the Pensieve beside him:

"Professor, didn't you say last time that you didn't understand magic circles very well?"

In modern magic, magic circles have almost been lost. Only some rudimentary magic circles are used in alchemy, and most of them are arranged using ancient magic patterns and then enchanted. This is why Dumbledore was so surprised by the teleportation circle made by Douglas last time.

Dumbledore shrugged and said:

"I can't, but don't I have you? I've already thought about it. You design a magic circle that can protect the memory material, and then use a Muggle laser to burn the magic circle into the recording layer of the disc. Then we use magic to store the memory. This will also effectively prevent people from cracking our technology."

Dobby blinked his big eyes and suddenly had an idea:

"Sir, can we use the magic of the house-elves to help? We are very good at some subtle magical manipulations, and perhaps we can help with the magical transformation of the disc.

Furthermore, Dobby's attempt to use a Muggle laser to burn the magic patterns might not be effective. Using elven magic to burn them directly would provide a safety net. After all, few people pay attention to the magic of house-elves.

Sirius stroked his chin and said thoughtfully:

"That's an interesting idea, but we first need to figure out the compatibility between the house-elf magic and our regular magic, to avoid accidental magical conflicts that could damage the disc or memory material.

Hey, no one would have thought that a disc would contain the skills of wizards, house-elves, and Muggles."

As the last bit of holiday leisure drifted away with the summer breeze, the new semester at Hogwarts began with the urging of the first ray of sunshine over the Black Lake.

With mixed emotions of excitement and reluctance, the students bid farewell to the laziness of the holiday, stepped back into the familiar yet mysterious campus, and quickly immersed themselves in the courses of the new semester.

In the early morning, before the first ray of sunlight completely dispelled the mist, the sound of orderly and powerful footsteps could be heard in the open space in front of Hogwarts Castle.

Professor Lupin stood tall and straight on one side of the clearing, like an ancient pine tree, still resolute despite having weathered wind and rain.

Since the end of this trip and his attendance at the Heroes Memorial Meeting, his temperament has quietly changed.

He has a thin face, but exudes an elegant temperament from the inside out. A few strands of hair flutter gently in the breeze, adding a bit of casualness to him.

Those deep eyes were like the twinkling cold stars in the night sky, gazing at the running students gently and firmly, as if they could see through the hearts of every student and give them silent encouragement.

He was wearing a somewhat old but neat robe, the corners of which swayed gently as he walked, and his every move showed his composure.

The weekend Defense Against the Dark Arts practice classroom remains one of the busiest corners of Hogwarts.

During the evening study time, students from all grades flocked to the study room with enthusiasm and desire for magical skills, making the originally spacious classroom seem bustling and overcrowded.

The freshmen opened their eyes wide, holding their wands nervously and excitedly. Following the demonstration of their seniors, they carefully tried out elementary defensive spells. Although the power of the spells was still immature, their seriousness was touching.

The senior students were more calm and confident. They gathered in groups of two or three, practicing their skills with each other. Brilliant magic lights flashed in the classroom from time to time, accompanied by the sound of spells and occasional exclamations, creating a warm and tense learning atmosphere.

In another corner of the campus, seventh-grade seniors are still taking on a special challenge - a level-breaking game transformed from a secret room. Unfortunately, no student has been able to complete a single subject so far.

This has led to professors of various subjects raising their expectations for seventh-grade students, and the seventh grade, which used to be relatively free, has now added additional tutoring courses.

Chapter 326: Hogwarts School of Witchcraft and Wizardry Final Exam Batch Examination System

The wizarding world outside Hogwarts is also in turmoil.

The much-anticipated Quidditch World Cup is about to be held in the UK. It should be a carnival feast for all wizards, but as the event approaches, a cloud of uneasiness is quietly looming.

The Ministry of Magic is well aware that such a large-scale gathering can easily become a breeding ground for dark forces to stir up trouble. In order to ensure the smooth progress of the event and the safety of the majority of wizards, Aurors came out in full force and launched strict patrols and control across the UK.

In the streets and alleys, and in magical villages, you can see pairs of Aurors in black robes and with stern expressions everywhere. They always hold their wands tightly in their hands, and their sharp eyes scan every move around them, not missing any suspicious signs.

In this tense atmosphere, two people were huddled in a remote country village, living in constant fear. They were Wormtail and Voldemort.

Voldemort, who once was so powerful that he wanted to rule the entire wizarding world, was now in such a precarious situation. Due to the unprecedented increase in patrols by the Ministry of Magic, he and Wormtail were forced to hide from place to place, like frightened birds, and dared not show themselves in public at all.

In the small, dim farmhouse, Voldemort's skinny figure hid in a package, his face distorted with anger and unwillingness. The red eyes that once frightened countless people were now burning with rage. As he became emotional, the densely covered words on his body would appear in different colors.
