Exchange student at Hogwarts

Following the strange sounds, Harry and the four of them wandered around the second floor, and in an instant they came to an area they had never been to before.

"Harry, what the hell is going on?" Ron said, wiping the sweat from his face. "I can't hear anything"

"Follow him, I also felt some movement." Zhang Chen frowned, "Fuck, this consciousness can only be released for twenty meters, which is really a hindrance."

They followed Harry to the third floor again, almost covering the entire third floor. Hermione suddenly stopped, called to everyone, gasped, and pointed down the corridor.

"Look"

On the wall in front of them, something glistened. They approached slowly, squinting to make out the details in the darkness. Between the two windows, on the wall a foot high from the ground, there are some writings daubed on it, which shine in the light of the burning torch.

"The secret chamber has been opened,

Be wary of those who are enemies of the heir. "

There is also a strange black shadow under the writing.

"What's that hanging down there?" Ron said, his voice trembling.

"It smells of blood, follow me." Zhang Chen blocked them and slowly approached. There was a large puddle of water on the ground, and Harry almost slipped. They approached the sign little by little, staring intently at the black shadow below. The four people saw what it was at the same time, and jumped back in fright, causing a splash of water. "It's Mrs. Norris"

Filch the caretaker's cat, its tail hanging from the torch stand, its body as stiff as a board, its eyes wide and staring. The three people stood motionless for several seconds, and then Ron said: "Let's get out of here quickly." "Should we try to rescue him..." Harry said not very fluently.

"Listen," said Ron, "we don't want to be discovered here."

"Yes, some things can't be explained at all." Zhang Chen is not a womanly person, and fully agrees with Ron's Mingzhe strategy of protecting himself.

But it was too late. A low noise, like distant thunder, told them that the banquet had just ended. From both ends of the corridor where they were, there was the sound of hundreds of feet climbing up the stairs, as well as the cheerful chatter and laughter of people after they had had their fill of tea and food. Then, students crowded into the aisle from both ends.

When the people in front saw the upside-down cat, the lively and chirping sounds suddenly disappeared. Harry, Ron and Hermione stood alone in the middle of the corridor. The students fell silent for a moment and crowded forward to watch this terrible scene.

In the silence, someone spoke loudly.

"Those who are enemies of the heir, beware that you will be next, Mudblood" is Draco Malfoy. He had already pushed his way to the front of the crowd, his cold eyes became vivid, and his usually bloodless face turned red. He looked at the still and stiff cat hanging there with a sinister smile on his face.

"What's wrong with my cat, my cat, Mrs. Norris?" Filch heard the sound and rushed over. He screamed at Zhang Chen and the others, "You, you, you killed my cat. You killed it. I want to kill it." I want you to pay with your life if you die.”

"Filch" Dumbledore arrived on the scene, followed by many other teachers. In the blink of an eye, he passed by everyone, flicked his wand and unhooked Mrs. Norris from the torch holder.

"Come with me, Filch," he said to Filch, "and you, Zhang, Mr. Potter, Mr. Weasley, and Miss Granger."

Everyone came to the classroom of Defense Against the Dark Arts teacher Lockhart. Dumbledore put down Mrs. Norris and kept tapping her with his wand. Finally, he muttered something. Professor McGonagall and Snape were also walking around. He went there and observed carefully, while Harold kept making suggestions on the side. At one moment, he said that this must be a transformation and torture curse. He knew how to solve the curse but it was too late now; at the next moment, he said that he had seen it in Ouagadur. Similar phenomenon, and he used the amulet to protect an entire village of people. I don't know if this method was an afterthought or a fantasy, which made Zhang Chen feel dizzy and wanted to knock him out with a punch.

"It's not dead, Filch. It's petrified." Dumbledore observed for a long time, tried several spells, and finally determined Mrs. Norris's current situation.

"Ah, I think so too," Lockhart added quickly.

"It is impossible for second-year students to do this," Dumbledore said firmly. "It requires the highest degree of dark magic."

"They did it, especially Harry Potter. He is a troublemaker. He wanders around the school every night. He was found in my office." Filch burst into tears and his fat face turned red. " Found out I was a squib.”

"I haven't touched Mrs. Norris at all," Harry shouted. "I don't even know what a squib means."

"Principal, I don't think the chance of a dark wizard sneaking into Hogwarts is very high, but I remember reading in the book Fantastic Beasts and Where to Find Them that some magical creatures can cause petrification. Is it possible that some magical creatures are responsible? "Zhang Chen already knew the answer when he heard the word petrification, and took the opportunity to put forward his own spoiler opinion. Ron explained the details of their participation in Nick's anniversary party.

"It's possible." Dumbledore gave Zhang Chen a deep look, and Zhang Chen nodded gently to Dumbledore. Dumbledore then looked at Harry with a searching look. Facing the gaze of his piercing blue eyes, Harry felt like he was being seen through.

"As long as you are not proven guilty, you are innocent, Filch." Dumbledore said firmly. "Mrs. Sprout recently obtained some mandrakes. Once they grow to maturity, I have a potion that will bring Mrs. Norris back to life. Everyone, please disperse, Zhang, and Harry, come with me." .”

Arriving at Dumbledore's principal's office on the eighth floor, Zhang Chen sat down opposite Dumbledore in a familiar manner: "A cup of hot cocoa and some food, thank you."

Harry was a little nervous and sat half-assed next to Zhang Chen, very reserved.

"Relax, Harry, what do you want?" Dumbledore looked at his little disciple with a kind face.

"Same as Zhang."

"Professor Dumbledore, on the way back after attending the anniversary party, I heard a strange hoarse scream, and kept saying some evil words, such as, I am going to kill you, you damn thing and so on. We also found Mrs. Lolita by following the voice." When Harry faced Dumbledore, he didn't need Zhang Chen to remind him. He told him everything he knew, and he quickly told everything that happened that night as if he were pouring beans out of a bamboo tube.

"Old Deng, I suspect that there are some magical creatures or ghosts that can walk through the walls of Hogwarts. This matter must be clarified, otherwise it will be a very big security risk." Zhang Chen carried out his own analysis.

"Harry said that only he could hear Zhang, couldn't you hear it either?" Dumbledore asked for more details.

"Yes, I can't hear it either. I can only feel that there is something moving at high speed in the wall. You know that after I have achieved success in Xuan Gong, my consciousness cannot be released, but I also have the ability to illuminate the sky and see the nature. Ability, I can sense danger or powerful enemies very keenly. This time I feel that there is a very powerful creature not far away from us."

After hearing Zhang Chen's narration, Dumbledore also realized the seriousness of the matter, "I will investigate the entire Hogwarts. This castle is too big, and there are many secrets that even I don't know."

"Some things are lost in the dust of history. Only the castle itself knows." Zhang Chen said a strange thing, and then told Dumbledore about the information he got from the ghosts at night: "The ghosts told me at night that in the south of France There have also been several incidents of unicorn deaths. Lao Deng, you need to find someone to check it out. Some things are better not to be taken out of the fire. Danger can be strangled in the cradle."

"I never thought I would need you to teach me a lesson, haha. I will handle Voldemort's matter myself, and I will tell Filch and Snape to investigate Hogwarts. It's getting late, you go to bed." Dumbledore said The arrangements were flawless, Zhang Chen and Harry went back to the dormitory after eating some desserts.
