Hogwarts Passer-By Professor

"Does that mean the school changed the name of Defense Against the Dark Arts?" Ron preempted the words.

Hermione and Harry showed understanding, and then looked at Eisen as well.

"Basically it can be said that." Eisen nodded and said, "But the Defense Against the Dark Arts course was not canceled directly, but left vacant."

"Is there any difference?" Ron couldn't help scratching his head, "Since the name of the course has been changed to Defeat the Dark Arts, isn't the Defense Against the Dark Arts course still vacant, isn't it redundant?"

"I don't know, maybe Dumbledore has other ideas." Eisen shook his head decisively, not telling them the truth of the matter.

"Never mind the name of the class, what do you think Sirius is going to teach us?" Harry patted Ron on the shoulder.

"Will he teach us Annie Magus to transform?" Speaking of which, Ron suddenly became excited.

"That's impossible. Annie Magus Transfiguration is the content of Transfiguration, something that Professor McGonagall wants to teach us." Hermione retorted directly, "Besides, human body deformation is a very advanced content, and it will wait until we are in sixth grade. will teach us."

Ron smiled mischievously, but said nothing.

"Okay, don't think so much!" Eisen interrupted the discussion of the three, "The exam is over, so you don't have to stay up all night, you go to sleep."

...

Early the next morning, when Eisen was wandering around the school, he found that the entire castle was almost deserted.

The hot weather suddenly turned and stopped, which made many people breathe a sigh of relief. At the same time, because the exam was over, many people took time to visit Hogsmeade.

However, for Eisen, there is no need to worry about these. In addition to flipping through books in the library to fill the memory palace in the dream world, Eisen has been working on his magical abilities.

Of course, the trio was completely free.

In the second week of June, the last day of term, the school announced the students' test results.

Harry, Ron, Hermione, they passed every class. Yes, they even passed Snape's Potions exam.

Fred and George, narrowly passing the Ordinary Wizarding Ranks, took their owls certificates. As a graduate who is about to graduate, Percy successfully passed the most advanced s exam and successfully obtained the certificate.

At the end-of-term dinner, Gryffindor successfully won the Academy Cup because of his outstanding performance in the Quidditch competition. So, at the dinner, Dumbledore transformed the scarlet and gold decorations to celebrate.

Everyone was celebrating, especially the little wizards of Gryffindor, and everyone was laughing. Of course, compared to Gryffindor, the atmosphere of Slytherins on the other side is not so friendly.

The next day, the Hogwarts Express stopped at the station, waiting for the little wizards to board. Eisen meets the trio in the auditorium.

Apparently, after breakfast, they were going to go their separate ways.

"I went to see Professor McGonagall this morning, just now. I have decided not to take the Muggle Studies class." Eisen was sitting with Harry and the others at dinner, and Hermione broke the news out of nowhere.

"You have plenty of time and your test scores are excellent, how could you suddenly think of giving up?" Eisen looked at Hermione in surprise.

You know, Eisen not only gave Hermione a bracelet that can make her full of energy, but also gave her time to increase the buff. Eisen was a little surprised that she had dropped Muggle Studies anyway.

"Yeah, your test score is 320 percent!" Ron couldn't help but say.

"I know!" Hermione looked at Eisen, blushed a little, as if she was sorry for Eisen's hanging up on her, and hurriedly explained, "I feel a little uncomfortable with the frequent use of that timer. I have already handed it in Well, after Muggle Studies and Divination, I have a normal schedule."

"Very good, I support your decision!" Eisen nodded, but didn't blame anything. Anyway, Hermione can decide for herself.

"You didn't tell us about the timer, no wonder you can appear in two classrooms at the same time." Ron looked a little bitter, "Aren't we your friends?"

"That's really cool! Hermione, you should have told us earlier—" Harry nodded in agreement.

"I promised Professor McGonagall not to tell anyone." Hermione said solemnly, then seemed to remember something, saw the smile on Professor Eisen's face, and her face turned red again.

"Harry, are you coming to live with me during the holidays? I'll talk to my parents. I'll break the conversation with you. I already know how." Ron looked at Harry and changed the subject.

"That's a phone call, Ron!" Eisen corrected him.

"Okay, call. Thanks Professor!" Ron went on. "How about the Quidditch World Cup this summer? Come to my house and we'll go to the games together. My dad can always get some tickets."

"Yeah, I bet the Dursleys would be happy to let me go. Especially after what I did to Aunt Marge." Harry said, his face not so happy.

"The Dursleys?" Ron showed a surprised expression, "Don't you live with Sirius Black? Are you going back to the Dursleys?"

"That's right, Dumbledore told me I had to go back to the Dursleys' house once a year!" Harry said with a dejected gesture.

"Why is that?" Ron couldn't help but ask.

Seeing this situation, Eisen suddenly understood, presumably it was Dumbledore who told him about Harry's protective magic.

Next, as expected by Eisen, Harry briefly explained his situation. It was only then that Ron and Hermione realized what was going on.

"That is to say, the magic on your body requires you to go back to the Dursleys' house once a year to ensure that you will not be harmed by Voldemort?" After listening to Harry's explanation, Ron showed a look of shock on his face.

"Yes, Dumbledore used magic to connect the blood relationship as a bond, let me live with Aunt Petunia, and the protective magic on me will continue to protect me. Until I am an adult." Harry couldn't help but say Sighed.

"Dumbledore said you would go back once a year, right?" Ron asked suddenly as if he had thought of something.

"That's right!" Harry nodded as he ate the roll.

"But he didn't say how long you'll stay once you go back—" Ron suddenly laughed, "You can go to the Dursleys' house for a day, or two or three days, and then come and live with me? "

"Is this okay?" Harry was stunned for a moment.

"Well, theoretically there should be no problem." Eisen pondered for a moment, and then slowly said, "The effect of Dumbledore's spell is blood relationship as a bond, extending the magical protection on your body to the concept of home. Extends the duration of magical protection.

And the purpose of going home once a year should be to strengthen the bond that Dumbledore was connected with through spellcasting. If this is the case, then there is no need to stay for a long time, one day is enough. Of course, to be on the safe side, it would be better for you to stay for a few more days. "

"That would be really nice." Harry was finally in a better mood when he learned that he didn't have to stay at the Dursleys' house all the time.

"Harry, you don't have to go back to the Dursleys' house during the summer vacation." Hermione suddenly suggested, "Didn't Dumbledore say you have to go back to the Dursleys' house once a year? You can choose to go back to the Dursleys' house during the Halloween holiday or Christmas." Go back during the holidays."

"That's right, Harry." Ron immediately agreed, "In this way, during the two months of summer vacation, you can live with Sirius Black."

"By the way, Professor Eisen." When Harry was enjoying himself, he suddenly looked at Eisen, as if he suddenly thought of something, "Dumbledore seemed to cast a spell on me after he told me these things."

"Spell? Is it the one that makes you go back to the Dursleys once a year?" Before Eisen could speak, Ron couldn't wait to express his opinion.
