Evan told him part of his conversation with Keresis, the suspicious figure he had seen in the hallway with Hermione last night, his suspicions about Professor Moody's identity, the recent events in the wizarding world, his concern that Voldemort was regaining strength, and the conspiracy going on at Hogwarts. Pen, fun, and www.biquge.info

Although there was a lot of exciting news in it, Evan didn't see any surprise reaction on Dumbledore's face.

As he expected, he already knew about it and was prepared.

Dumbledore generally agreed with and supported Aven's response, and promised to cooperate......

As for the few loopholes in the entire discourse, Dumbledore didn't ask about it, nor did he ask Evan if he knew about it.

Anyway, every time Evan looked up, he could see the principal's kind and encouraging smile, as if encouraging him to say more.

It's a terrible feeling!

What Dumbledore's intentions were, Evan didn't know.

He tried not to look into the other person's eyes the whole time, because that was the key to the dementor's mind.

All in all, after agreeing on what to do and deciding on what to do, Evan left the principal's office.

Instead of rushing downstairs to the auditorium for lunch, he walked down the corridor on the eighth floor to the wall of the Room of Requirement.

It is a blank stretch of wall, devoid of portraits and decorations, and on the opposite side hangs a tapestry of the silly Barnabas teaching trolls to dance ballets.

The Room of Requirement is also known as the "House of Coming and Go" and can only be entered when one really needs it.

It comes and goes, but when it does, it's always arranged to meet the needs of the person seeking help.

To get into this room, you need to concentrate and think about what you need.

Walk back and forth in front of this wall three times, and the room you need will appear.

Evan was inside the secret room where the potions were prepared, and for the past year, he had become very proficient in how to enter the Room of Requirement.

After making sure that there was no one around, he walked back and forth in front of the empty wall three times.

In his mind, Evan thought he needed a place to hide.

When he ran through for the third time, the door appeared!

Evan pushed the door open and entered, and inside was a room the size of a cathedral.

The pillars of light cast by the high windows reflect a city with high walls.

It was all made up of items that had been hidden by generations of Hogwarts people, and had been densely packed for thousands of years.

The streets and alleys were lined with crumbling piles of broken furniture, perhaps crammed here to hide evidence of mistaken magic, or hidden by house-elves who maintained the castle's decency.

There are thousands of books here, undoubtedly banned, scribbled, or stolen.

Among the piles of items were winged slingshots and wolf-tooth saucers, a few of which were still limp hovering over the mountains of forbidden objects, and some broken bottles containing solidified potions.

On top of that, there were hats, jewelry, cloaks, things like dragon eggshells.

A few gagged bottles still glowed with an evil light, along with a few rusty swords and a blood-stained axe.

It was the first time that Evan had been here, and he was shocked by what he saw.

This room hides secrets for nearly a thousand years, and it contains illegal items hidden by countless Hogwarts students, as well as the evil results of thousands of forbidden experiments, and countless secrets and useless miscellaneous items.

For dark wizards and treasure hunters, this room is simply heaven to be able to find something satisfying here.

But the whole process takes time and takes a lot of time.

Even if Evan knew a rough idea, it would be difficult to find Ravenclaw's crown.

"The crown is flying!" he tried, raising his wand.

It didn't work, nothing happened.

This room is protected by mysterious magic, protecting what is hidden here.

As for the ontology and operation principle of the Room of Requirement, Evan has always been curious, who left this magical room?!

It is able to prepare rooms and various props according to its needs, and that room obviously did not exist in Hogwarts Castle before, cannot be identified by the map, and only exists in the user's mind.

But these assumptions can be embodied in the real world through the Room of Requirement.

This room involves extremely advanced spatial magic and wishing magic, and Evan still hasn't figured out how it works.

He even speculated that the Room of Requirement was connected to Hogwarts Castle through a door, but in fact the main body existed in the void, which was the space through which the evil god existed and the apparition appeared, and now he could enter the void world by pushing the surrounding walls to it.

Of course, this is just a guess on the part of Aven, who knows what exactly is outside the wall, and whether it is suitable for human survival.

Space magic is a very esoteric and complex branch of magic that has always been at the forefront of research in the wizarding world.

Aven's gaze skimmed through the piles of debris, and then walked into an alley among the piles of treasure.

After walking a few steps, he saw a specimen of a troll, a full fifteen feet tall.

It was contained in a large glass bottle filled with potions that seemed to be green as preservatives.

Evan smacked his tongue and made trolls into specimens, which was a strange hobby.

One can imagine the image of a mad wizard who lived hundreds of years ago practicing dissection with the corpse of a troll......

Next to the troll specimen was a small pile of dusty books, and Evan picked up the top one and flipped through it.

This is a "Manifesto of Knights", which records the code of conduct of knights at the end of the Middle Ages, as well as several practical combat techniques.

It seems that a student from a knightly family brought the book to Hogwarts.

He put the book down and picked up a black-covered magic book.

It's also a martial arts book, which introduces the techniques of using a spear to charge.

Evan put the book down, and felt that something was not quite right, so he took out his wand and tapped the book gently.

"Show your secret!"

As soon as he finished speaking, the black ink on the book faded into red handwriting, complete with terrifying patterns.

It is a hidden book of dark magic, and the dark magic it says is called "Hell Howl".

This black magic can actually produce a terrible wail in a person's spirit, making him feel fear like never before.

The spell itself can be classified as a hybrid of soul and demonic magic, which Evan had seen in the library before.

However, the records on the book in his hand are not exactly the same as those in the library, and changes have been made in several key places, and Ewen can be sure that using this magic according to the spells and wand swings on the book during the battle will definitely not have the desired effect.

If you don't get it right, it will be a counter-spell that will damage the caster's own soul.

It's really scary, whoever it is, it's not good to leave this book here at all......
