"Actually, it's nothing to tell you." I thought I was angry, but Harry and the others became a little restrained, but I took the initiative to say it, "I know that the tragedy of my family is a huge weakness in my heart, so when I was sensible, I used the meditation pot to replay that night over and over again until I could calmly watch everyone in the family being killed."

Hearing my words, Harry and the others shivered suddenly. They suddenly felt that I was often expressionless and being indifferent to anything was actually an understandable thing. After all, if someone can remain calm in the face of the blood of his family, what else can surprise him?

"But it's not good to do this, child, after all, you are still a child, and you still have a wonderful life." At this time, Professor Lupin came back and said to me.

"Thank you, professor, but my last name is Harvey." I answered very politely, but with distantness.

"...Is it from Harvey?" Professor Lupin seemed to understand something. He nodded and said to me: "I understand why as a third-grade student, you can easily defeat a dementor, but I still hope you can live like a child."

"Thank you, professor, I will try my best." I still said in a calm tone.

The train started again, and we didn't talk much about the rest of the journey. Finally, the train finally stopped at Hogwarts Station. When we got off the train, it was really busy. The chirping of various animals resounded throughout the platform, and the small platform had already frozen and the cold rain was still falling. Seeing this situation, I added a waterproof spell and a warm spell to everyone in the box, so that we could at least walk into Hogwarts dryly.

On the way, Malfoy actually wanted to provoke us with the fact that Harry fainted, but we all thought he was air and no one paid attention to them. Professor Lupin, who happened to pass by, asked, which made Malfoy honest. However, when he saw the patch on Professor Lupin's robe and the ragged box, he returned to his arrogant look.

When entering the castle, Harry and Hermione were taken away by Professor McGonagall, but they soon returned and missed the branch ceremony - but I always felt that it was nothing, as long as I didn't miss Dumbledore's next words.

"Welcome!" Dumbledore said, his beard shining with glittering light from the candle, "Welcome to Hogwarts in the new school year! I have a few words to say to you all, one of which is very serious, and I think it's better to make it clear before you are confused by this delicious meal..."

Dumbledore cleared his throat and said, "You must know after they searched the Hogwarts Express. At present, our school is going to receive several dementors from Azkaban. They come here to perform official duties in the Ministry of Magic."

He paused and continued, "They are stationed at all entrances to the school venue. During their stay, I must make it clear that no one is allowed to leave the school without permission. Dementors will not be deceived by tricks or disguise - even in the Invisible Clothes." He added without expression, Harry and Ron glanced at each other. "Dementors are born to not understand what a request or excuse is, so I warn each of you: don't give them any excuses to hurt you. I hope that the predecessors, as well as our newly appointed presidents of the Boys and the Girls Student Union, you must ensure that no student will clash with the Dementors."

Percy was sitting only a few seats away from us, and at this moment he raised his chest again and looked around in an impressive manner. Dumbledore paused again, and he looked around the auditorium very seriously, no one moved or made a sound.

“It’s more gratifying,” Dumbledore continued, “I’m happy to welcome two new teachers to our ranks this year.”

"The first one is Professor Lupin, who is willing to accept the vacancies in teaching the Dark Magic Defense."

There were some scattered and uninviting applause from the audience. Only the students who had met him on the train applauded vigorously, and Slytherin was simply quiet - Professor Lupin sat among all the well-dressed teachers, which made him look particularly shabby.

"Look at Snape!" Ron whispered.

Potion class teacher Snape stared at Professor Lupin along the teacher's long desk with resentment. Everyone knows this reason because Snape always wanted to be a teacher in the Black Magic Defense Arts class.

"As for the second teacher we appointed," Dumbledore continued after the unenthusiastic applause for Professor Lupin disappeared, "Well, I regret to tell you that our teacher in the Conservation of Magical Biology, Professor Keitelborne, retired late last year to have more time to be with his remaining little naughty, yet, I am happy to say, it is not someone else, but Rube Hager to fill his vacancy, who has agreed to serve as a teacher in addition to the hunting ground guard."

Harry, Ron and Hermione stared at each other and were stunned, and then they joined the applause, and the applause on the Gryffindor table was particularly warm. I clapped and looked at Hagrid's red face, staring at his big hands, his smile hidden in his messy black beard.

"We should have known it long ago!" Ron shouted excitedly, pounding the table, "Who else would let us get a biting book?"

At this time, we found that Hagrid was secretly wiping his eyes with a tablecloth.

"Well, I think the important things have been finished," Dumbledore said at the end, "get to eat."

After using up the rich meal, Dumbledore announced his sleep, which made Harry and the others find an opportunity to congratulate Hager. Hager was also extremely excited and sighed. It seemed that I still have to do the work of pouring cold water.

"Hag, although I know I don't have this qualification, I still want to give some suggestions on the lesson you are taking," I said to Haag.

"Oh? You said." Hagrid was still excited, and seemed to just agree to my words casually.

"Hagir, are you going to introduce us to some huge, dangerous creatures in your first class? Of course, I mean the creatures that are dangerous to us." I asked. Hearing my words, Hermione suddenly showed an enlightened expression and looked at Haiger.

"Oh, probably, I'm going to introduce you to the first class of the eagle-headed, horse-body winged beast." Hager replied.

"Oh my God! Hagrid, you will lose this hard-earned job if you do this!" Hermione exclaimed, and Harry and Ron nodded in horror, because you can tell from the name that this is not a gentle animal.

"But, I think the eagle-headed, horse-body winged beast is a very interesting animal..." Hagrid was a little at a loss for the sudden blow.

"You're a little aggressive, Hagrid." I said gently, "You can make some cute and dangerous creatures first, such as Jueyinbird or Moonmad beast, or even unicorns."

"Unicorns are good, but Jueyin Bird or Moon Mad Beast...they are not interesting..." Hagrid said with some doubt.

"Hagge, now you are our magical biology teacher, and you should consider our reactions rather than your point of view." Hearing this sentence, Hage was a little dissatisfied, and I paused and continued, "Then, Hage, at Hogwarts, you are the person most familiar with Forbidden Forest, right?"

"Of course." Hagrid raised her chest.

"You know everything inside, right?" Hermione understood what I meant and then said.

"You're right!" Hager replied proudly.

"Then, as long as we go step by step, Hagrid, you will become the best magical biology teacher in Hogwarts' history!" I said in a sure tone at the end.

"Fortunately, Lina, you realized this and reminded Hagrid, otherwise the first magical biology class would turn into a disaster." Hermione said with lingering fear after Hagrid left.

"You should understand what kind of animal Hagrid likes. If no one says to him, he will have more than 90% chance of doing this." I shrugged and replied.

In this way, our third semester began. During the first magical biology class, Hagrid really followed our advice and did not bring the eagle-headed, horse-body winged beast, but a unicorn cub. Although this cub hates all men except Haig, it also excited the students - including the students of Slytherin.

Harry and the others encountered many unknowns in the divination class, all kinds of strange unknowns - these were said by Professor Trelawney, the teacher of the divination class. When they told me and Hermione about this, we had the same reaction, which was to sneer, but Harry seemed to believe one of the prophecies, because he encountered a black dog the night he left Dursley's house.

"In London in the 70th century, many people abandoned their pets for one reason or another. These pets could only wander in the city. There must be many black dogs. Is it true that those who see these black dogs will die?" I said a little unhappy.

Professor Lupin's black magic defense class surprised us. Although he was not well dressed (Ron's words) and seemed to be a little malnourished (this is Hermione's observation), his first class brought joy to all of us. His first class introduced us to a creature called Bogt, and it also taught us how to defeat it. This creature called Bogt will become what you fear the most. He feeds on people's fear, but laughter will hurt it and can even kill it.

The most exciting part of this class is that the professor asked Neville to deal with Boggart. Boggart became Snape - obviously, the one who was most afraid of was Snape. However, after the professor's guidance, Neville successfully defeated Boggart with a spell, and he made Boggart - or Snape become a long, lace-embroidered woman's suit, wearing a tall hat, with an old eagle specimen that had been worm-eatened, and a huge scarlet handbag was swaying in his hand, which made people laugh at the first glance.

OK, professor, maybe this is your teaching method, but how do I think it is like avenging private revenge?
