"Facts speak louder than words." Catherine didn't say anything more, she directly waved her wand to make an address book on the spot, and then Ixissi couldn't help but be stunned.

For Catherine's process of making zuò was indeed as she had announced, without the slightest deviation, but there was no accident at all that happened to Ixissi.

"It's exactly the same, but why would I directly destroy my real room at the last moment?" Ixissi was puzzled.

"At the last minute, it's just a magical network connected to the castle!" Catherine looked at the address book she had just made in her hand, and then jerked into her right hand.

"What's wrong?" Ixissi immediately noticed Catherine's anomaly, "Did you find out what the problem was?" ”

"Yes." Catherine smiled wryly, "I forgot that Hogwarts Castle's magical network is not something that anyone can borrow at will. ”

Ixissi was stunned, and his eyes widened suddenly, and he exclaimed, "Don't sue me, my experiment just now invaded the school's magical defense system. ”

"Yes, and—" Catherine lowered her head and said unusually embarrassed, "because you're already an eighth order, Hogwarts Castle judged your threat level to be high, so that's why you ......"

Catherine didn't say any more, for Exissia was already clenching her fists and wand, and was glaring at herself through gritted teeth.

"Catherine!" Ixissi shouted loudly, "Do you know that I will graduate in five months, and if I am punished by the school at this time, or even worse, how can you let me explain to my family!" ”

"Tell you the truth, Senior Ixes!" Catherine blinked her eyes and said with an innocent face, "When I announced the method of making the system, the people in the know who had the ability to verify it were all professors in the school, even if Percy was unexpectedly promoted to the eighth rank later, he obviously couldn't control his magic power freely until he graduated. ”

"And I'm a guy who has the ability to verify. But unluckily bumped into you and disappeared suddenly, but I couldn't resist my curiosity and desire to learn, and I tried it rashly like Gryffindor. So—" Exace slammed down the cabinet next to it, cried out angrily, "I did it myself!" Is that right? ”

"Nope! If it weren't for my negligence, Senior Ixas, you wouldn't have had this kind of accident. Catherine solemnly apologized, "So allow me to compensate you for your loss!" ”

"And what if the school gets me in trouble?" Ixissi raised an eyebrow.

"Professor Snape is currently in the medical wing, and Headmaster Dumbledore's eyes and ears can't yet access Slytherin, let alone the space behind 'SC'." Catherine smiled confidently, "So please rest assured, Senior Ixis. I'll take care of that. ”

Ixace let out a long breath before apologetically, "I'm sorry, Catherine, please forgive me for my selfishness, after all, this is the first time I've broken into such a big accident and invaded the school's magical defense system—" He shook his head self-deprecatingly, "I'm afraid that adult didn't even do anything like that when he was in school!" ”

"He who does not know is not guilty!" Catherine reassured, "What's more. If I hadn't published this method and carelessly forgot to explain why, this would not have happened. ”

"Oh!" Ixissi suddenly looked at Catherine meaningfully, but did not dwell on it. "Then again, have you forgotten one thing?"

"How could I forget that incident!" Catherine smiled and said, "If it hadn't been for the accident before, I wouldn't have had time to talk to you in detail." Know your wishes, so you don't dare to make your own decisions, so now when you are free. I immediately rushed to ask the seniors about you. ”

"Here, allow me to solemnly ask Your Excellency if you would like to join the SG team?" Catherine's attitude was unusually serious.

Ixissi replied with a wry smile: "After this happened, can I still not join?" ”

"Apparently not." Catherine smiled brightly, handed the newly made address book to Ixissi, and then took out her own.

Katherine To-All: Now allow me to introduce a new member, my senior, Brast. Ixissi.

Ixissi To-All: Good evening, everybody.

Prefects?—Draco, Pansy, Breth, Daphne, Theodore

It's me! -- Ixissi

The Slytherin students immediately began to give a variety of welcome speeches, and among these flowery words, one was particularly striking.

Welcome! - Percy

Percy, are you sure you're right? - George

It should be "fuck off", right? - Fred

George! Fred! You two don't mess around here! Makes you laugh, Prefect Ixes! You're welcome to join us! - Hermione

Welcome. - Harry, Ron, Neville

Hello! Slytherin prefect, I'm Luna from Ravenclaw. Lovegood. - Luna

That's Megan from Hufflepuff. Jones. It's a pleasure to meet you, no, you should be very welcome! I'm sorry! I'm stupid to speak! -- Minegen

Ginny. Weasley salutes you, Brast. Governor Ixes! Please forgive me for the ridiculousness of my twin brothers! - Ginny

Our dearest sister! How can you be so eccentric! - Fred

You can't be snatched away by the blonde beauty of Slytherin! - George

Weasley Twins! If you two dare to make up rumors about my sister again, then I will dare to beat you two up in front of the whole school! - Daphne

Sister! Ginny and I are just friends, just like Megan and Luna. - Asteria

My dear! Need help you find the Weasley twins? - Theodore

Remember to let me know when you find it! I'm going to do it right away! -- Brays

Since the two of them have itchy skin and need to clean it up, I think it is also appropriate to reluctantly help them! - Draco

It's too cheap to beat them up! - Pansy

The next time you talk about this kind of revenge, don't let me know! - Dumbledore

There was silence in the address book for three seconds, then it was broken by Ixasi's statement.

Hello! Headmaster! I'll be optimistic that they won't cause trouble in the school. -- Brast

Hehe! It's okay! It hasn't happened yet, has it? - Dumbledore

Ixissy and Catherine couldn't help but look at each other, but before they could do anything, Dumbledore spoke again.

Catherine, you're free tomorrow morning, right? - Dumbledore

The red-haired girl hesitated for three seconds, because whether it was the accident leaving the school or the accident that Ixissiy had just caused, Dumbledore could roughly guess her attitude, and the headmaster also knew that Catherine had just taken a leave of absence, and Snape and Lupin were still arguing over her schedule, so he asked so specifically in the address book, and the only explanation was that something happened that he didn't expect, and it also involved Catherine.

Something? - Catherine

Yes, there is something. - Dumbledore

I'll be free tomorrow after breakfast. - Catherine

Come to my office then. - Dumbledore

Good! - Catherine

"I remember the Headmaster's pet, it looks like they can walk freely through Hogwarts!" Ixissi asked suddenly.

"Yes!" Catherine frowned slightly.

"Then why didn't the headmaster let it inform you privately?" Ixissi asked.

"There's obviously a reason why you can't do that!" Catherine closed her address book and smiled, "I think it's time for me to take my leave." Good night! Ixesi seniors! ”

"Good night!" Ixesy politely sent the red-haired girl away, "I hope I can have lunch with you tomorrow at noon." ”

Catherine glanced at Ixissi, then smiled, "Of course, I'll be waiting for you in the dormitory tomorrow at noon." ”

"Thank you!" Ixissi showed a pleasing smile, but with his half-darkened face at this time, it was really difficult to look at it directly.

"Goodbye!" Catherine hurriedly lowered her head, then turned and walked briskly into her dormitory.

As soon as her figure disappeared, Ixissi conjured a water mirror, then immediately clenched his fists and gritted his teeth at the door.

After breakfast in the dormitory the next morning, Catherine came to the principal's office, but as soon as she entered, she was shocked to find that everything had been blown into the corners, the wall decorations were all scattered, and the bookshelves and cabinets had fallen to the floor.

"What's going on here?" Catherine shouted in shock, "Is it because of last night's ......?"

"No, it has nothing to do with last night." Standing in the middle of the room, Dumbledore waved his hand, "This was the case a few days ago, but I haven't cleaned it up because I haven't figured it out yet. ”

"A few days ago?" Catherine asked.

"When you and Severus left Hogwarts, to be exact." Dumbledore paused for a moment, then looked at Catherine and asked seriously, "What do you know about the school's defenses?" ”

"Hogwarts' defense system is a super-large composite three-dimensional magic circle arranged by the four sages, but the elements of the magic circle are not all kinds of strange and precious materials, but inconspicuous walls, pipes, corridors, fireplaces, and even classrooms and rooms themselves, because the four sages used their abilities to completely transform this historic castle." With a wave of her wand, Catherine conjured up a three-dimensional map of Hogwarts and told her about her understanding of the school's defenses.

"Although the idea of turning the castle itself into a magic circle is enough to make all intruders take it lightly, what is really amazing is the ability they give the castle partial transformation, which diversifies the composition of the magic circle, thus making the school's defense system more complex and elusive, which is why the headmasters of Hogwarts must be sages, because only sages can use the full effectiveness of Hogwarts' defense system."
