The man behind Hogwarts

The stall owner said cautiously: "The wizards who just entered may be similar to the ones from two years ago. You'd better be careful. Something may happen this time."

"If you think something is going to happen, why don't you leave quickly?"

"Think about it, if something happens, what's the safest thing to do?" The stall owner smiled mysteriously.

What's the safest thing to do?

After hearing his words, William was slightly silent.

"If something happens, of course it is safest to operate with a large force."

Looking at the stall owner's calm expression, he secretly thought to himself, "It's strange that he had to move like a mountain. It turned out that he didn't dare to act alone, so he stayed in the gathering and wanted to follow the large army."

Seems solid and cowardly!

William asked: "Did you smell the blood on their bodies just now? I suspect they may have set up an ambush outside."

The stall owner's cheeks trembled: "What's the smell of blood? I didn't smell it."

"Did you really smell it? That's troublesome. There are two groups of them. This group of people often goes out and the other group comes in... If there is really an ambush outside, the people who left before will be fierce. There is less luck."

As he said this, his eyes lost their calmness and his face became ugly.

William thought for a while and asked: "Who organized this market? Are these people related to the organizer?"

The stall owner shook his head: "There is no fixed organizer of the market. All big shop owners contact each other spontaneously. Even if they have problems, we can't be sure who they are."

After continuing to ask a few questions and finding out that the stall owner had no other news, William immediately found Crohn.

Tell him the whole story and ask for his opinion.

In the cabin, the two of them sat on the chairs created by the transfiguration technique. Crohn listened quietly, unable to see other emotions on his cold face.

"It seems that there is probably something wrong with those people."

William asked: "Professor, I have a question, why did the wizards who left the assembly not use apparation to leave directly, but first walked outside the market?"

This was his problem all along.

Even if there are adverse reactions to using Apparition, wizards should use it more flexibly for such a convenient spell.

Moreover, Crohn made it clear that there is no 'anti-Apparition' spell here.

Crohn said softly:

"The reason is very simple. It is determined by the characteristics of the 'Apparition' spell."

"Apparition is a very advanced magic, and it is also a very dangerous magic. It is so dangerous that even many old wizards are very afraid of it."

"In addition to the basic requirements for casting spells, wizards also try not to use this spell in places where many wizards gather."

"Could it be that the number of wizards at the location of use will interfere with this spell?" William guessed.

"That's right." Crohn sighed, "If the difficulty when I use Apparition to the Muggle world is 1, then the difficulty when I use Apparition to Diagon Alley is 7, or even higher."

"Once the spell is cast incorrectly, life may be in danger."

"It is precisely because of this restriction that wizards prefer to use floo powder, flying broomsticks and the like when going to certain places."

Crohn's simple and straightforward explanation.

After hearing these words, William understood that although Apparition sounds wonderful, it also depends on the situation and the person.

Perhaps a strong man like Dumbledore could use Apparition without any scruples.

After thinking for a while, he said:

"We'll take a look at the situation tomorrow and decide."

"Professor, be prepared to notify the Ministry of Magic. If that doesn't work, you will have no choice but to call the Ministry of Magic."

Crohn nodded.

There are more than a dozen wizards in one group of the other party. No matter how confident he is, he can't say that he can leave safely under the siege of so many people.

William saw his serious expression and said with a smile: "Don't worry, if it doesn't work, we can still wait. It's also a good idea to wait for the market to end and leave with the large group."

Although the stall owner’s idea is timid, it is really useful.

After thinking about a few more countermeasures, the two of them relaxed a little, and William talked about his own curse.

"Professor, in the magic notes you gave me, I have learned the Iron Armor Spell and Mire Confinement, but I have not found the Apparition."

Crohn stopped drinking water and looked at him in shock.

"Have you learned these two spells?!"

It had only been two months since he gave William the magic notes. In such a short period of time, he had learned two such difficult spells.

William smiled calmly, "Yes, I learned it. These two spells are indeed quite difficult. I have been studying them during this time."

Crohn was slightly heartbroken.

He reluctantly took a sip of water and said thoughtfully: "William, do you want to learn how to apparate?"

He nodded, "This spell is very powerful in terms of displacement. Whether it's on the road, chasing, or escaping, it has an irreplaceable role. I definitely want to learn it."

But I heard that this spell is more difficult to learn.

Crohn thought about it and said, "The reason why I didn't record this spell in my notes is because I learned it at the Ministry of Magic and had a special period of training. It took me almost half a year to learn it. ”

"And if a wizard wants to use Apparition, he must obtain a license from the Ministry of Magic, otherwise it will be illegal."

"This spell is too dangerous.

William, how about you wait another two years before studying? At that time your magic is stronger and more docile, making it safer to cast the spell. "

A trace of worry appeared on Crohn's cold face.

He was really worried, because even Aurors had to use this spell with caution.

Even in Hogwarts, only students in sixth grade and above are eligible to learn this spell, and not everyone can. Those who want to learn can only pay for the training class.

The teachers in the training class are also elite wizards sent by the Ministry of Magic.

Even with such caution, many wizards suffer accidental casualties every year due to this curse.

After hearing this, William pondered for a moment.

After taking another look at Crohn's expression, he nodded.

Before Crohn could put down his worries, William said firmly: "Professor, do you know any other spells, any other spells as difficult as Apparition?"

"William, what do you mean?"

"First of all, I agree with you, Professor. The magic spell of Apparition is very special and must be used with caution.

However, I would not be willing to give it a try. Professor, you can teach me a spell that is equally difficult but less dangerous. If I can learn it, does that mean I can also use Apparition? "

Crohn thought for a moment, and suddenly his eyes lit up.

"There really is such a magic..."
