Looking at the pure potion in the potion bottle in front of him, Yang Su whispered.

"Hahaha~ Finally let me finish! I finally found that feeling, and I finally didn't need to rely on luck to complete the refining of this potion! ”

Putting the prepared potion in the preservation box, Yang Su left his dormitory. He decided to take a walk around the school, he stayed in the dormitory every day for the past few days, studying the enchantment, Yang Su felt that although his body had used a cleaning spell, Yang Su still felt that he was about to become moldy and needed to bask in the sun.

After finding a good position, Yang Su took out his sun lounger, and with a pair of sunglasses, he lay on the sun lounger leisurely to rest.

"Meow~" After watching Yang Su ignore him again, Schrödinger ran away to play alone, he had recently gotten close to Filch's cat. According to two Gryffindors, who asked not to be named, "It's a smart kitten, and sometimes we even suspect he's some Animagus. He was always able to take Filch and his cat to the secret passage where we were hiding. ”

In short, due to Yang Su's long-term indulgence, Schrödinger has become familiar with the layout of the entire campus and various secret passages. For some reason, he decides to help Filch and his cat catch the students who make mistakes.

Several times when Filch walked up to Yang Su to thank him for his help, Yang Su felt confused, and he didn't know about Schrödinger's recent events until a conversation with Ryan before the holiday.

Sometimes Yang Su feels like a failure, and he doesn't even bother to care about his cat. But on second thought, Schrödinger is not really a cat, although it is only a fragment of the soul of the body, but he is a person after all, ah, no. He's a sapient creature after all.

"Professor Robin, what have you been up to lately? It's been a long time since I've seen you put it here so leisurely. At this time, looking at Yang Su who was lying on the sun lounger, Dumbledore approached and asked.

"Why are you here?" Putting away his sunglasses, Yang Su straightened up and asked with a smile, "Aren't your things very busy?" ”

"yes, we've just hired a new Defence Against the Dark Arts teacher at our school. He's a celebrity. Looking at the leisurely Yang Su in front of him, Dumbledore said with a smile: "It's really busy, I just came back and I'm going to be busy again." I really feel sorry for Quirrell, if he had been stronger, maybe I wouldn't have been so busy. ”

"That's no way around it," Dumbledore said helplessly when he heard Chilo Yang say about it, "Who let his luck go bad?" I ran into Voldemort, a terrorist. I think he had only one way to give in. Even Voldemort, the remnant, is not comparable to ordinary people. ”

"I hope I don't look at the wrong person this time." Listening to Yang Su's words, Dumbledore said helplessly.

"I forgot to ask, who is the new Defence Against the Dark Arts professor, don't show this sad expression, I think there should be dozens of candidates on your list."

"Haha, when did you see it." Listening to Yang Su's words, Dumbledore smiled: "This is also something that can't be helped, almost every year or two the teachers of the Defense Against the Dark Arts class will have an accident, so you can only prepare first." The new teacher is my former student. Gilderoy Lockhart of Ravenclaw. The recipient of the Order of Merlin, who was also an internationally renowned person, should not be a Death Eater like Quirrell. ”

"I hope this Defence Against the Dark Arts professor can be a few more years, after all, if something happens once a year, even if you have a lot of people on your standby list, there will be times when you don't have enough."

"I hope so." Listening to Yang Su's words, Dumbledore suddenly thought of something, and then said: "By the way, I want to tell you a good news, there is an exchange student from the Huaxia Academy of Magic. Even though it's only been one year, he still takes your course. ”

"Hey, there's such a thing as an exchange student? How am I not the Tao? Listening to Dumbledore's words, Yang Su asked strangely.

"It was only decided this year. One exchange place per year. At the end of the semester, the respective students will be allowed to return. "I don't know how I got a notice from the school board out of the blue. As for the candidate to go to Huaxia, it was decided by the school board, and it seems that Percy, who is from the Welles family, has been confirmed.

"Seventh graders over? How old is that student who came? Listening to Dumbledore's words, Yang Su asked suspiciously.

"18 years old." Regarding Yang Su's doubts, Dumbledore smiled and said, "There is also only one magic academy in Huaxia. It seems to be a Muggle university with a branch. It is said that these Eastern shamans were taught by their elders when they were young. When they become adults, they take the college entrance examination together to determine the top 20 people to enter the school. Get some resources and magic books for practicing magic. ”

Listening to Dumbledore's description of the Huaxia wizarding world, Yang Su's impression of Huaxia deepened a little more in his mind. He had already roughly guessed the situation in the Eastern Magical Realm.

"I see, my magic is a system of its own anyway, and it doesn't conflict with other magic, they can learn it if they want."

"Well, since that's the case, I'll go back and get busy, I really don't know when I will retire and rest well."

Looking at Dumbledore's departing figure, Yang Su waved his hand, put on his sunglasses, and lay back on the sun lounger. He pursed his lips and said, "After a lifetime of hard work, I may not be able to let go of this school even when I die, these students." ”

……

Time flew by, and in the blink of an eye, it was evening. And Yang Su, who woke up, sighed a little about the passage of time, opened the dimensional crack, took out a small table and put it beside him, and there were knives, forks and saucers on the table. Yang Su had already informed the house-elves at Hogwarts that he wanted dinner. Soon there was a delicious treat on the plate, a large piece of fully cooked steak. A few pieces of bread appeared in the bamboo basket next to it. There are also several small plates next to the steak filled with various sauces.

After picking up a knife and fork and dividing the beef on the plate in front of you, you will stick the divided meat with a fork and move it to a saucer with sauce, dip it and put it in your mouth.

Yang Su doesn't know any table manners, he is not a foodie, and he pays attention to these things. For it, as long as it eats happily and likes the taste of the food, it's fine.

After finishing the steak in his own way, Yang Su picked up the white bread in the basket next to him and ate it.

A large steak with a few pieces of bread Yang Su's dinner is just that. After tidying up the chair, Yang Su took a walk around the campus. He planned to find Schrödinger and return to the dormitory. At this time, Yang Su guessed that Schrödinger should be at Filch's.
