New Professor at Hogwarts

Xia Ran suddenly heard voices coming from outside the castle. He opened the window and let the cold wind blow in. He looked around and saw many students returning from Hogsmeade Village and returning to school.

"Sirius, don't go out for the time being. The students are coming back one after another." Xia Ran muttered, "During the dinner, Crookshanks will help, and more people will gather in the auditorium. Then you can try Let’s see if we can catch the mouse Banban.”

"Remember, you can't expose yourself in advance, otherwise if the mouse Banban is not caught, he will definitely run away immediately, and we will never find him again in the future." Xia Ran gave the final instructions, fearing that When Sirius saw Scabbers the mouse, he became so angry that he couldn't control himself.

The big black dog barked "woof" to show that he understood the pros and cons.

"By the way, let Crookshanks go back later, otherwise we won't be able to open the portrait of the Fat Lady at the entrance to the Gryffindor lounge." Xia Ran added, characteristic of the wizarding world, the wizard's portrait has wisdom, although There is a big gap between him and his original body, but he can already communicate normally. As the guard at the entrance to the Gryffindor common room, the portrait of the Fat Lady will definitely not let Sirius in without a password.

Crookshanks was Hermione's cat. It was normal for him to come and go in the Gryffindor common room, and no one would suspect it.

The big black dog communicated with the big ginger cat Crookshanks again. Dogs and cats barked one after another. What about animals?

call out!

He put a soundproofing spell on the door.

About another hour or two passed, during which the owl delivered a copy of the Daily Prophet. There was no meaningful news in it, it was all gossip or insignificant news, such as the time when a respected wizard was young. A senior official of the Ministry of Magic - said to be a leader of the Department of International Magical Exchange and Cooperation - took a sick leave.

It was getting dark outside, the wind and snow were getting heavier, and the temperature was getting lower, but it was still hot inside the castle.

"Meow." Crookshanks called, slipped out of Xia Ran's office, and returned to the Gryffindor lounge with his tail wagging.

"Ah, Crookshanks, you are finally back. I thought you wouldn't come back for another night." Hermione hugged Crookshanks and said happily. She and Ron had just returned from Hogsmeade. Came back and brought Harry a lot of food.

Ron glanced at the sleeping mouse Scabbers lying on his lap and snorted coldly.

Because the mouse Scabbers is Peter Dwarf Animagus, when Crookshanks first saw Scabbers, he discovered the strange secret hidden behind Scabbers, and it is natural for cats to catch mice, so Crookshanks He wanted to catch Scabbers, but was stopped by others countless times, but this had aroused Ron's resentment, and he disliked Hermione, the big cat named Crookshanks.

This also led to a relatively tense relationship between Ron and Hermione. As a good friend of the two, Harry felt extremely troubled when he was caught in the middle.

"Okay, the dinner is about to start, let's go down." Harry said, and everyone else in the lounge began to leave for the great hall one after another.

"I need to put Scabbers away." Ron said, holding the mouse Scabbers in his hands, and returned to his boys' dormitory.

Harry noticed that Crookshanks' eyes flickered and stared at Scabbers.

Harry suddenly had a headache and said, "Hermione, please put Crookshanks back."

He knew that if Crookshanks really caught Scabbers and ate him, Ron would definitely break up with Hermione, but he felt that it would be too difficult for a cat not to catch mice.

"Okay," Hermione said.

After a while, Harry, Ron, and Hermione left the lounge talking and laughing, and a big ginger cat came to the lounge lightly and sat cross-legged in a corner. There are still a small number of students who have not left.

On the other side, Xia Ran went to the auditorium, while Sirius ate some pastries in the office and waited for the Halloween dinner time to officially arrive. The best time for him to act was when the teachers and students of the school gathered in the auditorium.

When Xia Ran arrived at the auditorium, it was almost full of people. Thousands of pumpkins with candles decorated the auditorium, a large group of live bats flying around, and many orange banners with burning flames. Like a colorful water snake, it floats lazily on the ceiling where the storm is brewing.

The food at the Halloween banquet was so delicious that Xia Ran couldn't help but take a portion of each and stuffed her mouth full of it.

Beside him, Lupine and Professor Flitwick were chatting animatedly, mostly about some strange things in the wizarding world.

On the other side, Professor Trelawney ate aloofly and slowly, as if deliberately distinguishing herself from Xia Ran and not wanting others to misunderstand that she was as rude as Xia Ran.

Xia Ran was thinking in her mind, wondering if Sirius had entered the Gryffindor lounge and caught the mouse Scabbers?

"Xia Ran, what are you thinking about? You look a little distracted." Lu Ping took a sip of wine and asked softly.

Xia Ran smiled and said, "It's nothing, I'm just stumped by a few spells."

"Haha, Xia Ran, it's banquet time, let's put the curse aside for now." Professor Flitwick, who was further away, laughed.

The banquet ended with a performance by the Hogwarts ghosts, who jumped out of the walls and tables and formed various formations to perform gliding performances.

Gryffindor's ghost, the nearly headless Nick, reenacted his beheading experience with great success.

At this moment, several senior students who had left the auditorium early suddenly pushed open the door of the auditorium, looking extremely horrified.

"Sirius, the wanted criminal Sirius, has appeared!"

The auditorium fell silent for an instant, and you could hear a pin drop.

Dumbledore suddenly stood up and asked, "Where did you meet him?"

"Gryffindor...outside the Gryffindor lounge!" the students said with lingering fear.

"A few teachers will follow me to the Gryffindor lounge. The other teachers will keep order, take good care of the students, and don't let them leave the auditorium." Dumbledore said immediately, and walked out of the auditorium resolutely.

Xia Ran immediately followed Dumbledore. He frowned. What did Sirius do? Did something go wrong at that point? Why was he caught by others and his identity revealed?

Lupine, Snape, Professor Flitwick, and Professor McGonagall, the head of Gryffindor House, walked out of the great hall together with Xia Ran.

The little wizards looked at each other with confused and frightened expressions on their faces. There were so many dementors standing guard outside Hogwarts, how did Sirius sneak in?

…

The portrait of the Fat Lady at the entrance to the Gryffindor lounge was not damaged, but the Fat Lady looked dazed, as if she had been under a spell.

The portrait rotated and opened, revealing the passage inside, in which bits of various books and pieces of clothing were scattered. The entrance to the passage was full of pits, as if a wizard had just had a duel here.

When Xia Ran saw it, her brows suddenly furrowed even more tightly.
