Professor of Gemology at Hogwarts

On the morning before Halloween, the atmosphere was obviously different from usual. Everyone knew that today was the day to go to Hogsmeade, and there was a banquet tonight - although in the past two years, there would be some problems before and after every banquet, the year before last it was Troll, last year it was a basilisk.

Gray looked at the large glass window of the auditorium. An ugly dementor flew past the window from time to time, and he didn't know what was going on at Crookshanks.

"What are you thinking about? Gray." Lupine asked.

"It's nothing, I just feel like there are things floating around outside all the time, and I'm not used to it."

"It's better if you don't go see them." Lu Ping said in a brisk tone, "Just right, do you want to see the things I purchased recently?"

"What did you buy?"

"A Grindylow, I put it in the tank and it's in the office right now."

"Grindylow, are you going to prepare for the Defense Against the Dark Arts class?"

"That's right, this course can't just have theory, it must also be practiced. Last time it was Boggart, and later it was Red Hat and Kabbah. This time it's time for the students to see Grindylow. No matter which course they take, they have to prepare for it. You can protect yourself and be prepared in the future." Lu Ping drank the remaining drink in the cup, "Shall we go?"

The school is much cleaner today. Many students have gone to Hogsmeade. There are only two people in the corridor, Gray and Lupin, which makes Hogwarts seem even more empty.

"It's a very quiet day today," said Lupine. "Even Peeves didn't come out to play any pranks."

"After all, many students have gone to Hogsmeade. Potter came to see me a few days ago," Gray reminded. "He wants to go to Hogsmeade, but it's a pity that his aunt and uncle won't give him a signature."

"Yes." Lupine said gently, "I understand. Do you want me to talk to him?"

"That's right. It's better to have someone to chat with than to stay alone in the lounge. Ah, maybe you can teach him a new spell." Gray said, "Remus, after all, you are his favorite Professor."

"Favorite professor?" Lu Ping smiled, "I am very happy to hear this evaluation. It is an honor for me to be praised and liked by others."

Gray followed Lupine into the office. There was a large water tank standing in the corner.A disgusting green monster with sharp horns pressed its face against the glass, making various grimaces while constantly stretching and flexing its long and thin fingers.

"You should have seen it, right?" Lupine said.

"Not actually, I've only seen it in textbooks."

Gray approached the water tank and looked at it carefully. Grindylow bared its green teeth at him, and then buried himself in a tangled pile of water plants in the corner of the water tank.

"Would you like a cup of tea?" Lupine said, looking around for his teapot. "It's very comfortable to have a cup of tea after a meal."

"Okay." Gray nodded, but his eyes did not leave the water tank, but observed Grindylow's form through the gaps in the water plants.

"Actually, it's not unusual. There shouldn't be any difficulty in dealing with it. Although it looks strange, it's not very smart and can be easily caught." Lupine tapped the teapot with his wand, and a stream of water suddenly spurted out from the spout. steam.

"Grindylows live in lakes. It seems that there is one in the Black Lake in Hogwarts. Why don't you just catch one?"

"You think too simply, Gray," Lupine said with a smile as he opened a dusty jar. "The mermaids living in the lake have tamed the Grindylow there. If I go there rashly, Trapping non-wild Grindylows will piss them off."

"Okay," Gray knocked on the water tank, but the Grindylow ignored him. "There are not many reliable magical beasts for sale now. Many things are unavailable, or they are priced at sky-high prices. I heard The hunters in the north will be better, but obviously, their prices are reasonable, but they are often squeezed out by local merchants in Diagon Alley and Hogsmeade."

"By coincidence, I really know a reliable hunter, and I got this Grindylow from him." Lupine raised his eyebrows, "I lived in the north for a while before, and got to know some local people. Many of them are The Wizard of Inverness.”

"His name is Logan Aarons, a man who always smiles and lives in Innricks Village." Lupine said, handing Gray a cup of tea, "You can try to talk to him about the price, but I’m a little curious, what do you want to buy?”

"Some of the more precious things," Gray took a sip of tea without changing his expression, "like horns of horned camels, loba venom, fairy wings, etc... Sometimes the research on crystals doesn't always go well, so a lot of raw materials are needed. After all, no one can be sure about the crystal."

"Well... I thought you were going to buy something that would surprise me." Lupine said thoughtfully.

I hope this Logan Aarons can play a role and find a breakthrough for the Footless Monsters.

After a while, when Gray walked out of Lupin's office and was about to go to the Owlery to inform Claire, he was walking down the corridor when he noticed a small figure not far away.

"Neville? Why didn't you go to Hogsmeade?" Gray was a little surprised.

"Uh... I lost the permission form. I forgot where I put it." Neville said a little embarrassed.

"Lost the permission form?" Gray raised his eyebrows, "The permission form should be at your grandma's place, right?"

"Yes, it was at first, but since the last time you and I talked, I felt that I should train myself and believe in myself, so I asked my grandma to get the permission form back and promised that I would not lose it. ." Neville scratched his head, "But it seems that's not the case..."

"Maybe you could get your grandma to sign another one."

"No," Neville shook his head, "My grandma is very angry. She said that in order to make my memory long, she won't sign for me this time..."

"Okay -" Gray glanced at Neville humorously, "Maybe this will be of some use to you."

Neville smiled sheepishly.

"By the way, Professor, have you seen Harry? I was just looking for him, and he didn't go to Hogsmeade either."

"I don't know, um... he may be in Professor Luping's office now, and Professor Luping has something to do with him."

"All right--"

Neville looked scared. He was halfway through his words when he saw Snape walking towards them.

Holding a slightly smoking goblet in his hand, Snape walked between Gray and Neville, expressionless, and squinted at Neville, who was frightened by his eyes.

"Maurice, I have something to tell you." He said directly.

Have something to say to yourself?

"Okay," Gray said curiously, "Neville, go back first."

"Goodbye, Professor." After saying this, Neville turned and left quickly.
