Hogwarts: Starting with full Unforgivable Curses

"Both require accumulating a large amount of magical knowledge and passing a series of rigorous tests. For example, Aurors need to be proficient in multiple areas such as defense magic, defense against the dark magic, and dueling skills, while healers need to have in-depth knowledge of herbalism, potion-making, and various healing spells."

The example Dylan chose successfully made most warriors who were unfamiliar with healing science understand just how difficult it is to learn this course or even access advanced knowledge such as "sympathetic magic".

As the warrior present who had the deepest understanding of blood magic, Viktor Krum reacted almost the instant Dylan finished speaking. He continued his analysis along this line of thought: "From the perspective of bloodline magic, our physical body is not that important. What is truly crucial is the connection between the soul and the blood."

“Dylan, you told us before that blood, as a ‘bridge’ connecting the soul and the body, originates from the heart. This means that the heart is the part closest to the soul and the core hub for the transmission of soul energy to all parts of the body.”

"The blood pumped by the heart can actually be seen as an extension of the soul. And black magic usually directly harms the soul. In this way, through the connection between blood and soul, we can indirectly heal the damaged soul, right?"

Dylan nodded approvingly and said affirmatively, "That's right, you completely understand the principle."

……

After the exchange.

Dylan went to get busy.

Harry, Cedric, and Draco walked down a relatively quiet corridor, where torches cast long shadows against the warm glow of the flames on either side.

Harry was the first to exclaim, his tone filled with the joy of his accomplishment: "I originally thought this exchange would just be a simple sharing of some healing magic techniques, but I never expected to learn so much, especially about blood magic and sympathetic magic, which completely exceeded my expectations."

Draco raised an eyebrow, his tone carrying a hint of his usual teasing: "So, you understood everything? I thought you were only interested in combat-related content and would find these theoretical things boring."

Harry shrugged helplessly and said honestly, "I'm not sure how much I actually understood. Many concepts are still a bit vague, but at least I got a lot of inspiration. For example, I finally understand why when we practiced the Patronus Charm underwater and tried to warm our bodies with the power of the Patronus, the warm feeling always started in our chest and then slowly spread throughout our body."

He paused, then continued, "I always thought it was just a coincidence, but now I know it's actually related to the heart being the core of the soul and blood. The Guardian Charm is magic originating from the soul, so its energy naturally starts from the heart, which is close to the soul, and then travels through the blood to other parts of the body. That's why the feeling of warmth starts from the chest."

Draco raised an eyebrow, a hint of disdain in his eyes, and said in a casual tone, "If even you can figure this out, I think everyone else here should be able to understand it easily. If we explain it according to the theory of blood magic, it's simply that the heart is the closest part to the soul, and the Patronus Charm itself is the embodiment of soul power, so the feeling of warmth will naturally emerge first from the heart... Harry, isn't that what you wanted to say?"

Seeing Draco's head held high and his condescending demeanor, Harry immediately frowned and retorted, "Knowing such obvious things is nothing to be proud of. Instead of showing off this knowledge that everyone knows, why don't you talk about things that even the other heroes might not understand—like what exactly 'similarity' and 'contact' in 'sympathetic magic' refer to? Can you explain that clearly?"

Draco, speechless after Harry's remark, turned his head away uncomfortably.

With only one day left before the start of the second event of the Triwizard Tournament, the midday sun shone through the sparse clouds, casting shimmering light on the Black Lake beside Hogwarts Castle.

A cool breeze, carrying a hint of moisture, brushed against Harry Potter's cheek. He had just finished a warm-up routine at the edge of the Forbidden Forest, and his arm and leg muscles still felt slightly sore. To prepare for a possible underwater match, he had been practicing breath-holding and underwater magic control almost every day, and now he wanted to dive into the Black Lake to test his newly mastered underwater movement spell.

Harry stretched his wrists and jogged along the gravel path by the lake.

The waters of Black Lake are a deep, dark blue-green, with a few water birds occasionally skimming across the surface, creating tiny ripples.

Just as he bent down to take off his coat and test the water temperature, he suddenly caught a glimpse of two familiar figures standing under the willow trees on the opposite bank of the lake.

One of the figures was tall and upright, wearing a dark wizard's robe, with slightly messy hair but exuding a cheerful air; the other was slightly thinner, wearing round-framed glasses, and had a gentle, scholarly demeanor.

Harry's heart skipped a beat, and he recognized them almost instantly.

"Sirius! Professor Lupin!" He couldn't contain his joy and shouted towards the opposite bank, his voice filled with disbelief and excitement, "How did you get here?"

Upon hearing Harry's voice, Sirius Black was the first to turn around, a wide smile instantly spreading across his face.

He waved at Harry, then raised his hands, opened his arms in a hugging gesture, and called out in a lighthearted tone, "Hey, Harry! Surprised? We came here especially to give you a surprise!"

Harry ran quickly across the small wooden bridge connecting the two sides of the lake and almost jumped into Sirius's arms.

The warm embrace reminded him of their reunion at the Screaming Shack last year, filling his heart with warmth.

After releasing Sirius Black, he turned to Remus Lupin, greeted him with a smile, then blinked and asked in confusion, "A surprise for me? But tomorrow is the second project, why did you suddenly come?"

"Didn't you tell me this in your letter before?" Sirius reached out and ruffled Harry's hair, his smile still bright. "You said you didn't know how the second event would be arranged, and you were especially worried that the audience wouldn't be able to see the underwater situation clearly during the competition, and that we wouldn't be able to cheer you on."

Harry followed Sirius's gaze and suddenly noticed a group of wizards dressed in Hogwarts support staff uniforms, busy around several huge baskets not far behind him.

The baskets were filled with dark green aquatic plants with large leaves that seemed to shimmer with a faint fluorescence.

The wizards took turns carrying baskets to the lakeshore, carefully dumping the waterweed into the Black Lake. Three or four of them first cast a Bubble Charm on their heads, creating a transparent membrane of air around them, before plunging into the lake, seemingly to transport the waterweed to a more distant part of the lakebed. Seeing this, a bold conjecture suddenly popped into Harry's mind.

He pointed at the busy wizards, then turned to Sirius, his tone uncertain: "Sirius, are they preparing for the second project? Could it be... I heard Hermione mention a rumor that the competition will have a special viewing method? Will these water plants turn into a temporary viewing platform after they reach the bottom of the lake? And then you'll have to go to the Black Lake to watch the competition?"

"Build an underwater viewing platform?" Sirius stroked his chin, seriously considering Harry's guess, then looked at him with a hint of curiosity in his eyes. "Harry, do you prefer this kind of viewing experience? If you were to design it, what do you think the underwater viewing platform should look like?"

"No, no, no, that's just a guess."

Harry quickly waved his hand, explaining somewhat embarrassedly, "I just saw them throwing seaweed into the lake and was curious about what the seaweed was for, that's why I thought that."

What I really want to know is how you plan to solve the problem of underwater viewing.

“We’re planning to broadcast your second project live!” Sirius suddenly lowered his voice, raising his eyebrows with a hint of pride. “I read in a Muggle newspaper that their TVs can broadcast sports games live, and you can see the live footage no matter where you are, as long as you turn on the TV. Now we wizards can do the same thing! I remember Muggles use a machine called a 'camera' to capture and save the footage, and then transmit the image to the TV screen…”

He pointed to the baskets filled with aquatic plants and explained, “We don’t use cameras; instead, we use ‘developing aquatic plants.’ These plants have special magical properties that allow them to automatically capture and save the surrounding scene, then transmit the image to a special screen, just like a Muggle live stream, so viewers can see the game in real time.”

"That's amazing?" Harry's eyes widened in surprise. "Can it really achieve the same effect as Muggle live streaming? Can it clearly show every movement underwater?"

“Of course!” Sirius nodded firmly, then took a folded white curtain from his pocket and handed it to Harry. “Would you like to try it yourself now? Just follow the instructions on the curtain and you can see the scene from our test just now.”

Harry excitedly took the curtain and carefully unfolded it.

The curtain is made of a very thin yet exceptionally durable material, and when unfolded, it is about the size of two newspapers.

Just as he unfurled the curtain, Sirius walked to a basket not far away, took out a clump of fluorescent developing seaweed, and held it to his chest, seemingly preparing to cooperate with him in testing.

On the white curtain, lines of clear text were printed in bold black ink, immediately drawing Harry's attention.

The title at the top reads: "Visual projection screen - Exclusive viewing equipment for the Triwizard Tournament".

The following is a detailed description: "This screen is made using the core magical principles of the 'Mirage Spell' and is designed to provide the audience with an immersive live viewing experience, clearly capturing every key detail of the competition, so that you can feel the tense and exciting atmosphere of the competition even if you are not at the venue."

Harry eagerly looked down, searching for the spell to activate the curtain.

He quickly found the key information in the middle of the explanatory text.

The activation incantation for the 'Displaying Projection Screen' is the same as the 'Mirage Incantation'.

Harry silently repeated the spell several times, feeling the rhythm of the pronunciation.

Judging from the pronunciation of the incantation, the "Mirage Incantation" is not complicated. As long as you accurately grasp the stress and ending sound, it should be easy to succeed.

He looked up at Sirius, his eyes sparkling with anticipation: "Sirius, I'm ready. Let's begin the test now!"

"Mirage!" Harry took a deep breath and, following the instructions on the screen, recited the spell word by word.

He deliberately slowed down, and after finishing the incantation, his gaze immediately fell back onto the curtain as he continued reading the remaining explanatory text.

Following the instructions, Harry turned his head slightly and focused intently on the blank area in the center of the curtain.

In just a few seconds, a faint glow suddenly appeared on the originally white screen, and then a clear image slowly emerged—in the very center of the image was the clump of developing seaweed that Sirius Black was holding up, and the fluorescence on the surface of the seaweed was particularly obvious in the image. On the right edge of the image, he could also see Professor Lupin bending down to count the basket next to him, his fingers occasionally jotting something down on a piece of paper, his movements so clear that it seemed as if he were right in front of him.

“Harry, look—” Sirius’s voice came from the side as he slowly approached Harry with the developing seaweed in his hand.

Almost simultaneously, Harry clearly heard Sirius calling his name from the screen.

He quickly looked up at Sirius in reality and found that the other was indeed walking towards him; then he quickly looked down again and his gaze fell back on the screen—Sirius in the picture was also moving towards the "camera," while Lupin, who was originally at the edge of the picture, had gradually disappeared from the screen's field of vision.

When Sirius reached Harry's side, Harry was surprised to find that his own image was also in the image on the screen—he was looking down at the screen, his hair was swaying slightly in the lake breeze, and even the surprised expression on his face was clearly visible.

“Then I mean…” Harry’s gaze shifted from the screen to the emerging seaweed that had been thrown into the Black Lake. A thought suddenly popped into his head, and he asked excitedly, “Through this screen, we can also see what’s at the bottom of the lake? That way, during the competition, you’ll be able to clearly see my movements underwater?” (End of Chapter)
