From Azkaban to Hogwarts.

"I need to know exactly what kind of harm he can cause, and I also need to convince him before we can talk..."

As William spoke, his body swelled up dramatically.

Unfortunately, he was missing one, or more than one—but it's not a big problem now. William swung his left hand and smashed down the giant's arm that was trying to pull the pine tree.

This is a more effective provocation than "What are you looking at?"

Grop started to roar, but William nimbly dodged it, circled around half a body length, and slapped him on the waist—unfortunately, the height difference was too great.

William then kicked out, trying to knock Gropp off his balance.

Hagrid watched anxiously from the sidelines, unsure of whom to help—hitting William was out of the question, and he couldn't bear to hit his own brother…

...

"boom!"

To Hagrid's astonishment, William vanished in a flash, then reappeared behind Grop, slapped the struggling Grop to the ground, sat down on him, and nodded to make sure he didn't intend to stand up.

"Perfect…"

William stood up, looked at Grop who was having trouble getting up, and resumed his previous demeanor. At this moment, Grop looked at William with a very 'kind' gaze.

“Don’t hit Hagrid…” William said, using hand gestures as he spoke.

The giant nodded.

“You are not allowed to leave this area,” William gestured, “five hundred paces away!”

Grop nodded, lying down. His comprehension was limited, but he could accept what William said.

"Very good, that's all!"

William shouted loudly—and sure enough, the smuggling experience of his teammates was still very effective.

Giants occasionally drop the hides of magical creatures. Defeating them and then communicating with them can lead to a large profit through a single trade… however, very few people can actually defeat them…

"William, can you communicate with him?"

"Just a few commonly used ones, not many..."

William was a little embarrassed. He had actually used magic normally, but he got a bit carried away and... so he used Animagus to transform and take him down...

'Wait... what's that over there?'

William pricked up his ears, joking and laughing with Hagrid, his right hand in front of him, while his left hand secretly made rapid gestures.

Chapter 572 The Mysterious Unicorn Umbilical Cord Blood

"So, William, you mean Klopp can stay in the Forbidden Forest?"

"Not yet. I don't have the authority to decide. I've only confirmed that his danger level isn't that high, and that given the limited area he can move in, he won't pose a greater threat to the students than other creatures in the Forbidden Forest..."

William explained to Hagrid with a smile, while constantly gesturing with his left hand.

Without the aid of a wand, casting a sufficiently powerful spell was still somewhat difficult for him.

But luckily, his opponent gave him enough opportunities.

As the last gesture was made, William swiftly drew his wand from his right hand and pointed it directly at the spot he felt was amiss.

Over there, the enormous trees began to deform wildly, their branches twitching as if they came to life, and the leaves that had just begun to show signs of life shot out like knives, covering the ground without leaving any blind spots.

Immediately afterwards, a violet spell shot out from William's wand, leaving a frosty white trail on the ground halfway through its flight—this was William's most proficient form of dark magic.

It's hard to imagine that an ordinary student could follow along without making a single mistake. William is more inclined to believe that the opponent is someone from the Dark Lord's faction, given the current pervasive danger in the magical world.

However, to his surprise, the transformation spell he had been preparing for so long failed. He even lost control of the tree. Instead of forcing the hiding creature out as William had hoped, it blocked its leaves and William's dark magic.

The powerful freezing magic almost instantly enveloped the battered tree trunk, and in a flash, a hard and crystalline ice shell appeared on the tree.

'This is troublesome…'

Before such a thought even crossed his mind, William had already cast the Iron Armor Charm and the Bubble Hair Charm on himself. "Run!"

He shouted at Hagrid and the giant whose name he had forgotten, then pointed his wand to the sky and his left hand behind his back to the other side, preparing to send a signal for help.

He can still make a judgment, whether he can win or not...

"Stop!"

Dumbledore shouted out in a helpless and slightly panicked voice. If the castle were to descend into chaos again, he wouldn't have time to clean it up!

Now, it's not McGonagall who's in charge of everything in the castle, it's him. Heaven knows how much cleanup work he'll have to do after this alarm is raised.

Dumbledore even regretted coming to watch the commotion—it was just a little noise, why couldn't he restrain himself?

But he can't just use Apparition to run away, can he?

That would be even more ridiculous—either admit to it, or prove that someone else has mastered the art of apparition on campus…

He could imagine how troublesome the latter would be: first, investigation and analysis, then targeted discussions, and then a comprehensive upgrade of protection... people would die.

"Ok?"

William paused for a moment, but his left hand behind him continued moving until Dumbledore came into view.

'Is he really the principal?'

He paused for a moment, then shook his head helplessly. If it were Dumbledore, it would be perfectly normal for his carefully crafted Transfiguration spell to fail—given Dumbledore's mastery of Transfiguration, the fact that he could successfully cast a Transfiguration spell so close to him was enough to prove that his hard work on Transfiguration during this period had been very effective.

"What brings you here, Professor?"

William was somewhat suspicious—he didn't think Hagrid bringing his brother along would frighten Dumbledore; he guessed Dumbledore already knew about it.

Watching the show?

That's even more impossible. Dumbledore isn't Adams; he wouldn't have that much free time...

'this…'

Dumbledore looked at William and Hagrid, who looked ashamed, and found himself at a loss for words.

Let's see what violations Hagrid has committed.

Hagrid certainly believed it, but Professor William on the other side...

Besides, stalking your own professor isn't exactly a good thing...

"I was taking care of some things here... I overheard some fighting, so I came to check it out."

The First White Wizard was not the First Conman; he hadn't put much effort into his eloquence, and the excuse he came up with on the spot earned him a rather puzzled look from William.

'Handling things?'

'It can't be herbs. Professor Sprout is at the school; Dumbledore doesn't need to find herbs.'

'It can't be a conflict within the Forbidden Forest. Hagrid has handled that very well; there haven't been any problems in years. Dumbledore wouldn't come personally.'

'Could it be...?'

William realized a reason that made Dumbledore evasive—Hordeal weapons!

"Yes, Hagrid doesn't know about Horcruxes, so Dumbledore can't explain it clearly..."

'These are the kinds of things that require personal involvement; you can't delegate them to others…'

'The Forbidden Forest is also part of Hogwarts. One can imagine the Dark Lord must have explored this treasure-filled place quite a bit back then—how come I never thought of that!'

He even admired Dumbledore's idea to some extent, but that wasn't important. The most important thing right now was to cooperate with Dumbledore to deal with the Horcruxes and, incidentally, trick Hagrid away.

Hagrid wouldn't casually mention Horcruxes, but Dumbledore had his reasons for not revealing them, so he could only silently apologize in his heart, just like Dumbledore…

"That's great! I was just wondering how to report this."

William smiled broadly, then nudged Hagrid with his finger and whispered, "While Dumbledore is here, make Grop look harmless, then we'll get his residency application sorted out."

Having received the hint, Hagrid quickly followed suit, and then, at William's prompting, took his leave—the excuse being to show Klopp around the new house to prevent Dumbledore from seeing him impolitely pulling up trees to play with.

"very nice…"

William watched his brother's departing figure and smiled. "I originally thought he and Mrs. Maxim would be together, then he wouldn't be so lonely. Now it's not bad to have a younger brother to talk to..."

“Yes,” Dumbledore nodded. He trusted Hagrid a great deal and naturally hoped that Hagrid could have a better life.

"So, Professor, you have a clue about the last Horcrux? It's hidden in the Forbidden Forest?"

???

How did you come up with the idea of ​​Horcruxes?

Dumbledore looked at William, unable to understand for a moment what his self-defense professor was thinking, connecting the Forbidden Forest with Horcruxes.

But after hearing what William said, he seemed to have some doubts as well.

The Forbidden Forest might just be where Tom hid his Horcruxes—how many Hogwarts students aren't curious about it?

'Then hurry up and search the Forbidden Forest to see if anything is amiss…'

He was just about to make that suggestion when he remembered the unicorn he had blessed…

Searching the Forbidden Forest was not too difficult for the professor of self-defense, and with him and Hagrid, although it took some effort, it was still feasible.

But what about unicorns?

That unicorn that's about to give birth, that's...

However, before Dumbledore could come up with an excuse to stop him, William, with the help of magic, had already climbed to the top of a tree and began to observe his surroundings.

"There's a unicorn over there, Headmaster!"

William shouted from the treetop—his detection magic was quite good, especially since the unicorn was currently lazily eating…hmm?

William's eyes widened. He tapped the treetop with his left hand, conjuring a long rope, and swung directly to the unicorn to observe it—he knew these magical creatures well enough to know he couldn't get close to it.

The core of his wand is the tail of this magical creature, and its tail hair has always been very valuable.

But few dare to hunt this creature, and the unicorn tail hairs on the market are mostly things that have fallen off on their own at some unknown time—even in the legends of the audacious smuggling gangs, harming this creature would bring bad luck to the entire team, causing them to be blocked by the attackers.

However, there are ways to deal with this creature. When you encounter it, you just feed it until it's full and watered, treat it like royalty, and then when it's full and moving around in the bushes, one or two of its tail hairs will naturally fall off...

Don't underestimate it—this thing is sold by the root, and the purchase price for a single root is over five gallons…

If he's lucky, this old man covered in gallons will start shedding his antlers—just like deer antlers—and then he'll make even more money, 20 gallons per antler, no bargaining.

However, as an apothecary and a somewhat skilled professor of self-defense, William knew very well that this walking Garon not only carried the legendary curse, but also a real one. As long as some unicorn blood was added to the potion, the opponent would experience an experience far more painful than the Cruciatus Curse while having their lifespan extended…
