"How could there be so many Death Eaters?" In the Ravenclaw break room, hearing William's answer, Ike asked with his mouth wide open and in disbelief.

"Of course, do you know how many Death Eaters there were who followed the mysterious man in the first place? In fact, basically half of the patriarchs of wizarding families in the British wizarding world are following the mystery man.

After the First Wizarding War, the patriarchs of most families have cleared their past. William recounted the history to a few people, and it wasn't a hard source to come by.

The wizards have never had a closed attitude towards these histories, but they have not paid attention to this knowledge.

In fact, if the students were careful enough, they could have deduced Snape's past based on the information available, just as Terry and the Weasley brothers did.

"Can it be whitewashed so easily?" Ike asked, a little incredulous.

"Of course, this is mainly due to the existence of the Imperius Curse, do you know the Imperius Curse Ike?" After setting up the silencer spell in all directions, William asked Ike.

For the sake of safety, the next thing he was going to say was not to let everyone in the lounge hear it, after all, it was not a great thing.

Thanks to the alchemy cards, the Ravenclaw Lounge is now very popular. Every time he returned to his dorm, William would find a whole host of different students from various colleges.

Suffice it to say, because of the game invented by William, there has been a lot more communication between the various colleges.

Prior to this, the main and most intense form of communication between the various houses was probably Quidditch.

"As you can guess from the name, this isn't a friendly spell." Ike craned his neck, and he sensed acutely that William might be about to say something terrible.

"Yes, this is an evil black magic, and the lowest threshold of the three unforgivable spells, he can manipulate the human soul, and if you can't break free right away, you will be controlled by the spellcaster, and act exactly according to the spellcaster's consciousness.

It's quite a scary thing, because when you do something that you don't want to do or can't do, your consciousness is clear, and you're clearly aware of what's going on, but you're powerless to resist. ”

William popularized some knowledge related to the three unforgivable curses like his friends, and the British wizarding world will become more and more chaotic in the past few years, William feels that his roommates still know some things better.

And even if he doesn't talk about it now, in two years' time, Professor Moody, who was dropped by Barty Crouch Jr., will talk to them.

Sooner or later, they're going to have to come into contact with it, and knowing it helps them realize the cruel and cold side of magic.

For wizards, magic is definitely a double-edged sword.

Therefore, with this consideration, William and several others talked in detail about how to resist the Imperius curse.

"In the face of a psychic attack, the best defenses that wizards can choose are undoubtedly two spells, the Occlumency Spell and the Patronus Charm."

The former can help wizards build a mental barrier in their minds against psychic attacks like the Imperius Charm or the Dementor Mind.

The latter, on the other hand, is a more sophisticated spell that can defend against not only psychic attacks but also some common evil spells and attacks by dark creatures, making it a very useful spell. ”

"We're both second-graders, how do you know so much?" Terry interrupted William's remarks in some confusion.

"Of course, because of studying, when you are acting as a quiet salted fish in the lounge or playing chess and cards, I am constantly absorbing knowledge, so although we are both in the second grade, I know and master a lot more than you."

"Alright, let me move on to the connection between the Imperius Curse and the Death Eaters' Transformation.

Due to the sudden defeat of the mysterious people at that time, they disappeared from the British wizarding world overnight, and these Death Eaters could not find their masters, so they were naturally powerless to resist the Aurors of the Ministry of Magic.

For this reason, most of the Death Eaters chose to protect themselves, and they all said that they had been seduced by the Imperius Curse unleashed by the mysterious man, and they had to fall into the darkness. ”

"And the British Minister of Magic at that time had no choice but to compromise in the face of this situation." While William was taking a breath, Terry ended up talking.

"Because there are too many of these wizards who have fallen under the Imperius curse, and most of them are also the patriarchs of various families in the British wizarding world, and the leaders of the major fields.

If the Ministry of Magic had really tried these people, then the British wizarding world might cease to exist.

The Divine Twenty-Eight have heard of it, and at that time, more than half of them had an inexplicable connection with the mysterious people, and there were very few people like the Crouch family who openly opposed the mysterious people, so you can imagine how huge the mysterious people were at that time. ”

"Lying about being under the Imperius Curse has allowed many wizards to escape trial, and the only Aurors at the Ministry of Magic have captured are the fanatical Death Eaters who are loyal to the mysterious people, and some of the hapless people who have been caught red-handed."

The two of them gave Ike and Earl a good understanding of this dark history.

"All I want to know now is, William, what's going on in that secret room?" Earl asked, a little frightened.

He was in the midst of the crowd of onlookers, and he heard Malfoy's shouts as well.

"It is said that during the time of the Big Four, Gryffindor and Slytherin had a disagreement over their teaching philosophy, as Slytherin did not like Muggle wizards, believing that their inclusion would be harmful to pure-blood wizards and the wizarding world.

The two had a big fight, and Slytherin left Hogwarts in a huff, but it is said that he left some decorations behind as he left.

This is the origin of the Chamber of Secrets, and wizards believe that Slytherin at that time most likely left such a secret room at Hogwarts so that one day his heir could return to the castle, open the Chamber of Secrets, and rid the castle of all Muggle wizards. ”

"That's all I know, these stories are so old that I can't tell if they're real or just legends made up by posterity." William told the few people in the room what he knew.

"That's all I know, and if we want to know something more specific, maybe we can ask the ghosts of Hogwarts again."
