Professor of Gemology at Hogwarts

The next morning, the clock tower bell rang.

"get out of class is over." Gray closed the book and said to the students in the classroom.

As usual, the students sorted the stones they used into wooden boxes in the classroom.After all the students left, Gray walked out of the classroom with two worn-out crystal science books under his arm.

Put the books back in the office, and then go to Hogsmeade - he had to see Sirius to feel at ease.

In the corridor, Filch stood at the door of the auditorium, holding a dirty mop in his hand to mop the floor. It had been raining heavily in the past few days, and the students who came back from outside the castle had trampled the corridor with mud everywhere. The corridor, which was dark because of the cloudy sky, looked even muddy.

"Why can't these annoying students clean the soles of their shoes!" Filch complained, "And this damn cloudy day! I have added several torches, but this gloomy weather makes people feel like At night. Those naughty students always take the opportunity to do some mischief, especially the Weasleys!"

Everything seemed normal, but at this moment, Gray saw a pair of eyes looking at him at the end of the corridor, in a dark blind corner, behind a strong pillar leaning against the wall.Suddenly, a bolt of lightning from the window not far away illuminated the dark corner - hiding there was the big black dog that Gray wanted to see.

Gray's heart almost rose to his throat. The big black dog that had been missing for several days actually appeared in Hogwarts Castle. After repeatedly making sure that no one around him noticed anything unusual, he walked straight to the corner. .

When the big black dog saw Gray noticing it, he stepped back and blended his entire body into the darkness.

"Leave quickly." Gray walked to the corner and whispered into the dark corner, "You shouldn't be here."

The big black dog raised its ears and barked twice in a low voice.

"We can't say much here. Let's go back to our old place quickly."

Suddenly, Gray felt a breeze, the air flow in front of him accelerated, and some things became distorted. Then a short figure appeared in front of him and bumped into him.

"Ouch!" the man cried out in pain.

Gray didn't see exactly when the man appeared, but he reacted quickly, took a step back, instinctively drew out his wand, and pointed it straight ahead.

A schoolbag fell to the ground with a thud, and the books inside were scattered all over the floor.He saw a girl with disheveled hair standing in front of him, covering her head with one hand and stuffing something into the pocket of her robe with the other hand.

"Miss Granger?" Gray lowered his wand slightly, "Uh... your head doesn't matter, does it?"

"It's nothing...ah, right...Professor Morris?" Hermione raised her head, and after seeing the wand in Gray's hand, she held her breath and showed a surprised look, "Yes...I'm sorry, Professor, I I accidentally bumped into you. I think I just ran too fast and didn't... stop at the corner..."

To enter this blind spot from the corner of the corridor, you need to pass behind Gray, rather than going directly to the front.Gray knew Hermione was lying and was afraid that his time-turner would be discovered by the professor.

"Okay, you have to be careful in the future. If you get injured, you'll be in trouble."

He wanted to follow Hermione's wishes and get this little girl out of here quickly. After all, there was a black dog hiding in the corner behind her.

"Thank you, Professor, I will pay attention." Hermione was obviously relieved when she heard Gray's words.

"tidy."

Gray pointed his wand at the pile of books lying on the ground. At the same time, he stood up his schoolbag, opened the mouth of the schoolbag, and put all the books scattered on the floor neatly into place.

"Thank you, Professor...Professor...?" But just as Hermione bent down to pick up her schoolbag, a flash of lightning appeared, and she saw two triangular pointed shadows (ears) on the stone floor under her feet. He turned around and saw a big black dog.

For a short moment, three people, no, two people and a dog, stood motionless.

"Oh my God, Professor..." Hermione began, "Where did it come from? Is there really a black dog in Hogwarts?"

The big black dog shrank back, but there was no retreat behind it, only a stone statue attached to the wall.Gray was about to send Hermione away when he saw her pick up her schoolbag and hold it in her arms. Everything seemed normal.

"No wonder!" Hermione said with a very certain tone, "Professor Trelawney may have seen it, which provided inspiration for the 'ominous' she made up."

"..."

The big black dog tilted his head.

"I have to tell Harry about this. There was a black dog in the school. If 'Ominous' was really so close to him, he would have died long ago. There is no need for him to be afraid. He believed in 'Ominous' too much. existence." Hermione sighed, "Professor Morris, I'm very sorry just now, but I think I have to go first."

Hermione glanced at the time, gave Gray an apologetic smile, and trotted past him, but as soon as her figure disappeared around the corner, Gray heard her speaking.

"Professor...Snape?" Hermione said.

Gray glanced at the big black dog and immediately turned around and left.

"Good morning, Professor Snape." Gray walked out like a normal person.

Snape looked past Hermione and towards Gray.

"What are you doing here?" Snape asked suspiciously.

"We... uh... I want to ask Professor Morris about crystal——"

"Am I asking you a question? Miss Granger," Snape said coldly.

"Miss Granger is right, milky quartz is very sensitive to light." Gray did not look into his eyes, but stared straight at his big nose. He put the "Mystery of Quartz" under his arm. "Took it out and flipped through it casually.

Hermione nodded in agreement.

"Talking about spar in a dark corner?"

Snape glanced at Hermione very suspiciously, and then fixed his eyes on Gray. Obviously, he did not believe this poor reason.

"If I remember correctly, class is about to begin, right? Miss Granger." Gray said.

"Oh, yes -" Hermione understood what he meant, "Professor, I think I have to go to class first." After that, she ran away.

"Let me pass." Snape's tone paused, and he almost said through gritted teeth.

"What?" Gray asked, "What was in the past?"

"I should be the one asking you." Snape said bluntly, "I heard something about 'Black Dog'. Now, get out of the way, Maurice."
