A Certain Hogwarts Magician Professor

"Today is a practice class."

Felix said from the podium. With a wave of his hand, hundreds of wooden jars appeared in the air, and these wooden jars floated in the air. Then he waved his hand again, and the space in the classroom began to expand in all directions, widening to half the size of the auditorium in the blink of an eye.

The students exchanged excited looks and whispered to each other.

Then, a quaint tome appeared in Felix's hands. He opened the first page, and a flood of ancient runes with bright colors poured out from the book, each half an inch in size. It looks like some kind of tiny flying creatures are entangled and connected, like an unrolled long scroll, and like a long ornate carpet - just not woven with thread, but made of rune .

Felix and the students silently looked at the rune that surrounded them like a wall for a while, and then said:

"Some of these runes are special, they can't be well integrated with the characters around you, all you have to do is to pick them out - both your eyesight and your skills, because a little carelessness will destroy nearby Structure... The next one is successfully picked, plus one point, you can use chestnut wood cans to store the extra rune symbols, the final score is related to the length of your homework today, let’s start.”

"Oh, yes, no wands. This will be the norm for future practice classes."

The students stepped forward one after another to choose their favorite jars, and Felix himself sat in the soft chair, recalling the just-concluded academic conference.

There were many people present, from all over the world. According to the original plan, the party in the evening of the first day was like taking the wind out of the dust. Real people don't match up.

Therefore, someone must act as a host, and the best candidate in Felix's mind is naturally Slughorn. The old professor was like a duck to water. After the whole party, the smile on his face never stopped.

The Tonks also came.

They stopped for a long time in front of the huge booth. In fact, they didn't quite understand what these people were discussing, and they couldn't accurately distinguish the meaning of the rune sequence frozen by Felix's magic, but every time they heard the exclamations of experts in their ears, the position in their hearts Just shake a point.

The hall on the first floor of the sword castle was overcrowded, and they searched for the figure of their daughter. Finally, they found her beside a spacious column, and Lupin beside him was calm but excited. He remembered Felix's promise-like speech: With the invention of the wolf poison potion, new theories will emerge one after another, and the werewolves will be better off.

To a certain extent, these words have indeed come true. In just the past two years, improved formulations of the wolf's poison potion have appeared, and the cost has been greatly reduced; the Ministry of Magic has also passed legislation that any registered werewolf can enjoy a discount on the purchase of the wolf's poison potion.

As a result, a considerable number of werewolves chose to be neutral during the war.

But none of this was more heartening to him than what he had heard earlier in the evening, that Lupin had learned of Felix's two solutions—ancient magic that would harness the transformation of a werewolf; and Deep human metamorphosis in which the internal structure of the body is deformed together - both methods he hopes to achieve, and the latter can even make him temporarily become a real human, which means that he can have a very healthy child.

God knows how ecstatic he was when he got the news.

In fact, werewolf symptoms are not 100% inherited to future generations, but for Lupin, this is equivalent to waiting for God's judgment. He has been tortured by werewolf for decades, and he can't bear this uncertainty.

There was also an interlude on the day of the dinner.

Lucius Malfoy made a high-profile appearance with his wife, and the couple were gorgeously dressed, promising a generous donation of fifty thousand Galleons for a good cause. This has brought many people who live abroad and are not politically sensitive around him to listen to him talk about his son Draco's "healer dream".

This effect...not bad.

"The paper said," Hermione said, carefully looking at the glowing scroll in front of her, which was like a tight brick fit together, "more than two hundred people were present, all of them potions, healers, and alchemists. Experts in three fields, as well as officials from the Ministry of Magic of different countries were present."

She put her right hand on the rune wall and easily took off a glowing ancient rune.

"That's a lot of money," Harry said admiringly.

"But the strange thing is that the host of the conference is Professor Slughorn." Hermione said.

"It's not surprising," said Ron, who saw that Harry had also successfully taken down an ancient rune, and eagerly reached for the glittering wall, "we all know he's good at this, think about it Who can deliver a heartfelt eulogy in the face of a giant, hideous spider corpse? Oh, no."

He groaned, trying to stuff the ancient runes he took down, but it was too late, and the dozen or so runes in front of him flashed a dangerous red light.

"boom!"

Ron was overwhelmed by the black smoke, he coughed while covering his mouth, and Harry and Hermione hurried to the side, nearly pushing Neville against the wall. "I'm sorry, Neville!" Harry said apologetically to Neville, who was rubbing his chin, with tears in his eyes. "It's okay."

Ernie on the side didn't pay attention to this little accident at all, and kept talking to himself, "Justin has scored six points, I don't want to lose to him."

When the smoke cleared, Ron muttered to Harry and Hermione in dissatisfaction, "It was fast enough, I almost sprayed the leaves of the mandrake, Hermione, you should have reminded me."

"The target you chose is right, but there is something wrong with the technique." Hermione pointed out his mistake, then flicked her fingers, dexterously took a rune from the wall and raised her hand towards him.

"As such, use your own magic to stabilize the connection points around. We just need to pick out the characters that look discordant, so it's easier."

"I know," said Ron feebly. "My attention has been diverted, and we shouldn't be talking about Slughorn, we might as well think about—" He paused, clenching his teeth like he was pulling blocks It's like taking down an ancient rune.

At the same time, a word came out of Harry's mouth: "Blood."

Hermione sucked in a breath of cold air, her fingers trembled, and a figurative character turned into pure magic, spreading out like smoke. "Be careful!" she cried nervously, quickly condensing an ancient rune from her fingertips and stuffing it back, the three carefully stared at the wall for a moment, until the red light above stopped flickering, they breathed a sigh of relief .

"It's an exciting game," said Ron justly, in a better mood.

Hermione glanced left and right. Everyone's eyes were attracted by the movement made by Cormac McLaggen. She took the opportunity to lower her voice and said, "I think it's better not to say it, especially when it comes to that person." She had an incredible look on her face, as if she was about to scream in the next second, but she tried her best to hold back.

"It's incredible, I mean the principal and..."

Harry was silent, and took the glowing characters from the wall, which he had seen from last week's Pensieve. At this point, he couldn't hide it. He was deep in it and desperately needed to find it. After discussion, the people he trusted most in the school were undoubtedly Ron and Hermione.

In the last lesson, Harry saw new, subversive memories.

Young Albus is in high spirits preparing for his graduation trip, but tragedy strikes him in the blink of an eye. His mother tragically passed away from Ariana's uncontrollable magic, and he had to return home to take care of his younger siblings. Harry saw his pain and anxiety the whole time, and for the first time blamed Albus for showing impatience. Of course, the person in the memory can't refute it, but the owner of the memory can, but Dumbledore all acquiesced.

This made Harry feel a little regretful. Put another way, if he had to stay with the Dursleys as an adult, he would absolutely go crazy. But that's his own family after all, isn't it? But when he saw Albus forming a friendship with a young man, Harry was genuinely happy for him.

until he heard that name.

"Hi, my name is Gellert Grindelwald."

Harry suddenly remembered the letter he had read. In the letter to Sirius, his mother Lily mentioned that Dumbledore and Grindelwald once had a good relationship, but maybe because of space limitations, Lily did not mention it in the letter. And the cause and effect, not to mention the time. So when Harry heard the name from the blond boy in front of him, who was not much older than him, he seemed completely defenseless.

What followed was a large fragment of memory, but enough to make Harry realize how quickly their friendship was progressing, and he even read a few glowing letters from a bystander's point of view, in a sudden, deeply uncomfortable way. The way is presented in front of him, Muggle, rule, government, army... These words appear in front of his eyes like thorns, constantly poking his heart.

But none of this compares to the picture that emerges from the barn.

Two men - two young men of future fame - Dumbledore and Grindelwald, face to face with wands to cut open their palms, then join hands, blood meet, and a blinding light illuminates the two Young and solemn face.

Harry felt dizzy. Finally, when the fused, indistinguishable beads of blood were covered in a metal shell, he asked aloud what it was, and Dumbledore was speechless, telling Harry almost compulsively in a weak but strong voice It was the "Blood Alliance", and he and Grindelwald made a blood oath.

The lesson came to an abrupt end, in the way Harry least wanted.

"Harry, Harry?" Ron called. "We're already behind, and I don't want to add two inches to my homework today."

"Got it," Harry muttered, busy but already made up his mind.

Before get out of class ended, students lined up to be tested.

"Susan Burns, 52, well done, homework - one foot; Anthony Goldstein, 47, one foot two; Millison Burst, 29, well, you need Practice a lot or you won't be able to keep up with the next stage - the work is a foot and a half long."

Felix commented casually, and the long queue gradually decreased.

Harry deliberately stayed in the back, holding the chestnut jar, waiting for Ron and Hermione to walk away and stepped forward.

"Harry Potter, let's see - 59, pretty high ranking, very good, seven inches of homework."

Harry racked his brains to ask two questions, anxiously waiting for the other students to pack their bags and leave the classroom. Ron and Hermione knew what he was going to do, waved at him, and left first. Felix looked at him thoughtfully.

"It looks like your real problem can't be heard by anyone else."

"Well, yes...Professor, I want to ask what is a blood alliance?"

Felix looked surprised.

He thought for a few seconds in his mind—

"There are many contracts in the magic world, ranging from verbal agreements with no binding effect to magic contracts. Among them, the most solemn and prudent type of contract is treated with care. Once signed, it cannot be violated. Because the cost of breaking it is too high."

"Dead?" Harry asked softly.

"...Yes, such as the Unbreakable Oath, and of course the blood alliance. It's just that the latter conditions are more stringent and only exist in legends."

"Why? Don't they have similar effects?" Harry asked in confusion. "Besides the number of people, the Unbreakable Oath needs a witness."

"I could say a lot of different things, like - like you said, the Unbreakable Oath takes three people," Felix said, and Harry blushed, feeling a little sluggish, completely ignoring the "many differences" the professor said. .

"But the most important thing is the content of the oath. The unbreakable oath is more flexible. I can swear that I will never eat chocolate frogs in my life, or I can let myself enter the door with my right foot from now on... In short, no specific requirements. But the blood alliance Different, it has its own magical core, no need to say the contract to abide by, which has a very serious impact, can you find out, Harry?"

Harry tried his best to think, no need to swear...what does that mean? Don't waste your tongue? No, not this... wait, no language... no restrictions...

"The blood alliance will not be deceived by lies?" he blurted out.

Felix nodded with a smile.

"The unbreakable oath is closer to the word 'contract', so the content of the oath must be determined in words, words... can be teased, there are always loopholes to follow, as long as the final requirements are met. In other words, it controls It's your behavior, and there's a certain lag."

"In extreme cases, a person with a will to death can sign any unbreakable, 'false' oath."

"But the blood alliance is not like that," Harry said excitedly. "It has a fixed content, which makes it impossible to be deceived by rhetoric, two people must be absolutely sincere, even the idea of ​​breaking an oath-" He looked affirmatively. to Felix.

"You guessed it right, the blood alliance binds the heart, and any thought of trying to violate it will immediately lead to backlash."

"And what was it about?" Harry asked impatiently.

Felix hesitated.

"As far as I know, they don't hurt each other."

"Can it be destroyed? I mean, a token of the blood alliance?" Harry continued.

Felix glanced at him, "Did I mention the token?"

"Oh, uh—"

"Maybe it can be destroyed." Felix did not pursue the loophole in Harry's mouth, but simply said: "I have never signed such a contract, and I don't know the specific results."

In fact, all the contracts he signed had one thing in common: he could tear up and twist them at any time. But he has no interest in touching those that are not sure to destroy - whether it is an unbreakable oath or a blood alliance. Knowing is also very limited.

Harry left with a heavy heart.

Felix stayed where he was, watching him disappear, then suddenly raised his head to stare at the ceiling, his eyes seemed to penetrate the wall. He stared thoughtfully at the location of the headmaster's office tower.

Maybe Harry didn't realize it himself, but the direction in his question was obvious.

"Blood... Dumbledore and whom? Evenly matched—yes, only Grindelwald."

Trivial information from the past keeps pulling from memory, and Felix tries to piece together a complete story. The first thing that came to his mind was the secret that Newt had inadvertently mentioned that could not be revealed more and involved Dumbledore.
