Hogwarts Blood Wizard

Hermione was startled by Ivan's guess, she was so surprised, she couldn't help but ask."You mean Professor Moody's imprisoned another person in the castle, so he needs to prepare extra food for him?"

"If this is possible, I would prefer that person hide in his office." Ivan nodded.

"That's why he doesn't allow the elf to clean his room..." Hermione muttered to herself, she already wondered why Ivan had asked those questions before.

"But why did Professor Moody do this? I heard that he was a powerful Auror before. He has captured a lot of dark wizards and Death Eaters. It is impossible to serve the mysterious man!" Hermione was very confused.

If Ivan hadn't told Moody's all kinds of doubts, she couldn't imagine that Professor Moody might be a bad person.

"I don't know... I'm just guessing!" Ivan shook his head. He couldn't be sure whether it was true or not. There were too many doubts.

Moreover, Moody himself is a very suspicious person. It is normal not to allow house elves to enter the room. This is also the reason why he has noticed something strange before but has no doubt.

"Could someone pretend to look like Professor Moody with the compound decoction and hide the real Professor Moody?"

Hermione immediately thought of the possibility, only then "Professor Moody" must provide food to another person, lest he starve to death.

"It shouldn't be... the time effect of the compound decoction is limited, unless he can replenish it at any time, otherwise it will definitely reveal the stuff!" Ivan shook his head. He had checked this a long time ago, and Moody did not carry the wine with him. It is the habit of the gourd to not drink a certain kind of beverage from time to time during class.

"In contrast, I suspect it is the Imperius Curse!" Ivan said hesitantly.

Hermione’s eyes widened. Of course she understood what the Imperius Curse was. Moody just explained the effect of this magic in the Defence Against the Dark Arts class this year. It can control a wizard without knowing it, and is even more affected. Listed as the three unforgivable curses!

"Moody is a very cautious Auror. His willpower is not weak. It is impossible for ordinary people to control him for such a long time. I guess it was a mysterious person who did it himself. And in order to prevent Moody from breaking free, he must be alone. Supervise him and consolidate the effect of the Imperius Curse regularly..." Ivan talked freely.

Ivan has also practiced such a practical black magic as the Imperius Curse, and is clear about the drawbacks of it being broken away by the strong-willed.

As for the solution to the shortcomings, it is not impossible, just like he controlled Nott, dispatching a special person to monitor and consolidate the Imperius Curse on a regular basis can greatly prevent the opponent from getting out of his control.

Of course, this method is not perfect.

Because it is easy to cast the Imperius Curse on the same person in a short period of time, it is easy for the other party to develop corresponding resistance, which greatly weakens the power of the spell, which requires more frequent spells, until it falls into an infinite loop.

Hermione’s understanding of Ivan’s curse was far less clear than Ivan’s, but she could understand the seriousness of the matter, so after Ivan finished her guess, she quickly dragged him upstairs. ."Since Professor Moody is under control, let's go and save him!"

"Wait, Hermione!" Ivan helplessly stopped Hermione's movements, and then said again in the little witch's puzzled eyes.

"I just doubt it, there is not enough evidence to prove it! What if Professor Moody is really a big appetite, and happens to like to eat midnight snacks when working overtime at night? This is not impossible."

Hermione was dumbfounded, she stared at Ivan blankly, and after a while, she pursed her lips in distress and spoke."Then... Then what should we do?"

"Of course I go back and think about it and see if I can find more clues in the past few days..." Ivan said hesitantly, but before he could finish this time, Hermione interrupted directly.

"Don't lie to me, you must be going to find Professor Moody alone later!"

The little witch bit her lip and stared at Ivan very angrily. How could she not guess that Ivan was going to fool herself, and then ventured on her own, and she couldn't hate to say a few words for a while.

But thinking that she might not be able to help with following, Hermione swallowed the words that had arrived again, feeling depressed in her heart, and finally had to whisper aggrievedly.

"This is too dangerous. You should at least tell Professor Dumbledore about this! What if this is actually a trap, and someone deliberately exposes a flaw to lure you into being fooled?"

Ivan looked at the little witch in front of him, sighed for a long time, and said in compromise."Well, you are right this time!"

Due to the inconvenience of revealing a lot of information, Ivan has become accustomed to solving all things by one person over the years, and occasionally has been tricked a few times, but Hermione reminded him this time that there is indeed no need to risk some things alone.

...

Half an hour later,

In the headmaster's room on the top floor of the tower, Ivan briefly explained his guess, while Dumbledore was pacing in the wide office with his brows frowned.

"Halse, can you be sure that Alastor was controlled by the Imperius spell?" Dumbledore asked.

Ivan shook his head. Everything he said was just guessing, and couldn't be 100% sure.

"Professor Dumbledore, is there no way to detect this kind of dark magic?" Hermione said suspiciously.

"Unfortunately, Miss Granger, as far as I know, there is no special counter-curse for the Imperius Curse, otherwise it would not be classified as an unforgivable curse." Dumbledore replied.

Ivan nodded. The magic of the Imperius Curse is very tricky. It once caused a lot of trouble to the Ministry of Magic. Death Eaters like Lucius used it to escape from sin. They rely on the Imperius Curse to be difficult. Features of forensics.

Only those clever masters can find some clues by browsing the memory.

But Moody's vigilance is really too high, if someone uses sanctuary on him, he will definitely be noticed.

Ivan recalled several previous contacts and found that Moody's almost always used that magic eye to look at himself. It was obvious that the other party was consciously guarding against this.

Dumbledore pondered for a long time. Alastor was one of his most trusted friends.

In the past half of the school year, the other party has not revealed anything wrong, everything is so familiar, so he never doubted this old friend, and even entrusted the other party with the heavy task of investigating the Goblet of Fire...
