"Not bad!" Dumbledore nodded approvingly, then asked, "And what do you think of Hogwarts' internal management?" ”

"Since Hogwarts is a school, the Four Sages, in order to avoid disgust from the students, gave the portraits in the castle the ability to move freely, so that the portraits became the eyes and ears of the professors."

"But because the resident staff of the castle are basically underage wizards who don't know the height of the sky, the four sages have also arranged a large number of sculptures in the castle in order to monitor abnormal magic fluctuations at any time and avoid accidents, but the recipient of this information is only the current headmaster." Catherine couldn't help but look at Dumbledore as she said this.

"In fact, as early as September last year, just a week after the school started, I noticed that there was an extra wave of magic in Hogwarts Castle." Dumbledore walked over to the three-dimensional map Catherine had conjured up and pointed his wand at a location, "It first appeared in Severus's office, then suddenly scurried around the castle, but soon returned to the basement, and since then, it has followed Severus wherever he goes." ”

"I tried Severus, but he obviously didn't know that he had an extra attendant, and I had followed Severus closely for a while, but I couldn't figure out where his attendant came from, so I went to the castle records and found that it didn't come from outside the castle." Dumbledore said this, and suddenly looked at Catherine through the three-dimensional map.

The red-haired girl smiled dryly, but didn't open her mouth to explain.

"I watched for a while, and at last noticed that though he seemed to be as withdrawn as Severus, he sometimes approached Miss Lovegood's White Rabbit and Miss Jones's pigeons, which gave me a bold suspicion that perhaps they were of the same kind, so I inquired about Miss Jones." Dumbledore lifted his glasses and looked at Catherine with a smile.

"Miss Jones was kind enough to tell me that her pigeons, as well as Miss Lovegood's white rabbit, hatched from the 'eggs' you gave me. Coincidentally, Madam Pomfrey told me that Severus saved you with an 'egg' on the night of school, so I guess you want to repay the favor and hatch that little guy with a hidden head and tail! ”

Catherine tugged at the corners of her mouth in embarrassment, but she couldn't smile a little.

"After I roughly figured out where the little guy came from, I didn't pay much attention to it, but now I know that I underestimated it at all." Dumbledore grimaced. Looking at his office, "Not only did you give it the ability to integrate into Hogwarts, but you also gave it access to the school's defenses. ”

"I didn't realize I had access to the school's defenses until last night." Catherine blinked with an innocent expression on her face.

"It's been more than a year since you got the key, not to mention the fact that I reminded ...... on Halloween night last year," Dumbledore could finish his sentence before Catherine interrupted him.

"Then I figured out where the key came from, and how it would affect my future—" Catherine spread her hands helplessly. "I ignored its purpose at Hogwarts."

Dumbledore stared at the red-haired girl for a long time and sighed, "Okay! This was indeed an oversight on my part, as there had never been a situation where a student had been given a key since Hogwarts was founded. ”

Catherine glanced at the principal's office. Then he cautiously asked, "How did it do it?" ”

"I was still behind my desk, just got up to go to the Great Hall, and then—" Dumbledore turned to look at where his desk had been, "a whirlwind appeared at my feet. Instantly enveloped my chair, and as soon as I tried to take out my wand, it spun harder. Bounce everything around you completely. ”

"Because the wind was so strong, I had to raise my hand to cover my eyes, and then I felt my body float, but before I could react, gravity returned, and I fell into my chair, and it was calm, the only thing that was unusual was that it was Severus's office."

"Space Move!" Catherine's cry of surprise was met with Dumbledore's glare, and she hurriedly lowered her head, but the joy on her face could not be concealed.

"I thought I had been tricked by illusion, but after checking with my magic, nothing was out of the ordinary, so I opened the door and went out to see if I was in the cellar, and then I was shut out." Dumbledore thought of the arrogance of the serpentine sculptures in the basement, and couldn't help but glare at Catherine again.

Catherine pretended not to see it, and took over with a smile: "Then you found out that we were missing." ”

"Yes!" Dumbledore sighed and said, "You also know what happened next, I hid the news and waited for you to come back, but I didn't know that both of you actually avoided me." ”

"Where's Fawkes?" Catherine said left and right.

"First it was blown by the wind, then it was flooded, and now I am still angry, I guess I went to which volcano for a vacation." Dumbledore sighed again, he didn't know if he had been unlucky recently, otherwise why would he leave his pet to play.

Catherine glanced at Tracy, who had been stepping on top of Dumbledore's head since she entered the door, and suddenly realized another use of the blue bird, and couldn't help but ask with a dry smile: "Is there anything else going on with the headmaster?" ”

"Two things!" Dumbledore reluctantly, "Take care of that little guy and bring my chair back." ”

Catherine glanced at the fireplace in the Headmaster's office and made sure that Dumbledore's plush chair was absolutely impassable, before nodding her head, "I'll do it now!" ”

"Go ahead!" Dumbledore waved weakly, looking at his miserable office again.

Catherine glanced up at Tracy, then turned and quietly left the Headmaster's office, and the little bluebird bounced twice above Dumbledore's head before spreading its wings and flying towards its master.

Catherine rushed to Snape's office in one breath and carefully inspected the room with her magic before seriously asking about her pet.

"What the hell are you?" Catherine asked, looking around cautiously.

[He lied to you] Tracey puffed out her cheeks.

"Thank you! Tracy! Catherine couldn't help but take the little blue bird into her arms, but then asked with a straight face, "Are there any sequelae?" ”

[How is it possible] the blue bird held his head high and looked proud.

Catherine tapped Tracey's little head with her fingertips before she looked at the unusually abrupt high-backed chair in the middle of the office, this fiery red wooden chair covered with velvet didn't match the black and green style of the room, and if Snape saw it, it would definitely be split directly as firewood.

But Catherine couldn't rush it out, as the Potions Professor's office was on the basement floor, and the Headmaster's office was on the eighth floor, so she had to take the secret passage unless she wanted to make it known.

[Under Headmaster Dumbledore's chair, open a shortcut to the door of the Headmaster's office.] Catherine uttered the command in the language of the snake.

This time, the red-haired girl could clearly perceive that when she gave the order, the castle immediately formed a detection magic array under the office, and then a magic wave quickly swept through her body, and after detecting the storage of the essence of water in her right hand, the castle transformed again into a teleportation magic array, and opened a space door on the floor of the office, connecting to the ceiling at the entrance of the principal's office.

As Catherine followed the high-backed chair through the space door, the space door closed above her head, and the teleportation magic circle immediately split into hundreds of independent modules and scattered to all corners of the castle.

"Headmaster!" Catherine knocked lightly on the door, "I've brought your chair here." ”

"Come in!" The door to the office opened, the clutter was gone, Dumbledore had magically put most of the things back in place, and only a few had to be carefully repaired.

Catherine magically returned Dumbledore's high-backed chair to its place, then softly closed the door and left.

As for Tracy, it had no intention of leaving its master's shoulder this time, for Fawkes had returned, standing on its gilded perch, holding its head high and looking down at the surroundings.

Leaving the Headmaster's office, Catherine used the snake language again to open a shortcut to the medical wing, but this time the castle did not make a spatial door, but instead created a zigzag slide, and the exit was on the wall of the medical wing, which happened to be directly opposite an empty bed, but the movement was still a little louder, alarming the others.

Mrs. Pomfrey did not reprimand Catherine for her actions, but glanced at her angrily, and went back to busy, but Snape, perhaps because he was idle, glared at the red-haired girl until she honestly came to her side to "listen to the lecture".

Snape and Lupin quarreled for a night and the result was no result, and the two couldn't convince each other at all, so the training plan made by the two, Catherine had to accept it all, plus the homework and review plans assigned by the professors of several other subjects, the red-haired girl immediately felt that five months was not enough time.

Snape and Lupin also knew that the training plan was in a hurry, so they both decided to choose a focus, which meant that they had to continue arguing, because they both thought that their own arrangements were the main point, so Catherine did not wait for the bell to ring, and immediately made an excuse to leave, and she did not even have the energy to listen to their quarrel now.

However, while listening to the training at Snape's side, Catherine also looked around distractedly, and soon she noticed the whereabouts of the "Patronus", but the little one was too cunning, and as soon as she noticed that the red-haired girl noticed her, she immediately fled into the castle.

Catherine didn't dare to let Snape notice, so she didn't continue her pursuit until she left the medical wing and returned to the Potions professor's office, when she spread out her right hand and revealed the four slowly spinning droplets of water and brought them closer to her eyes.
