The wizard in Hogwarts is unscientific

After the dinner, the prefects of each college need to send the first-year wizards to their dormitories. The second-year wizards and above can move around freely... However, on the first day of school, everyone still needs to tidy up their dormitories.

Andy is not so crazy that he goes to the library to read on the first day of school.

Back in the dormitory, Andy shared some snacks with his roommates and talked about their summer vacation lives.

There is an elective course registration form on the bedside table.

Andy signed up for all the elective courses as planned.

After washing, Andy lay quietly on the bed, thinking about the time turner he was about to get, and couldn't help but feel a little excited.

A magical item that can turn back time!

Logically speaking, no matter which world it is in, the props that can control time should be the kind of very high-end treasures - they are usually carefully kept and only used at the most critical moments to use them to change things. situation.

But in this world...

The time converter is just a learning tool, and its purpose is to allow you to take a few more elective courses.

So low!

No matter what Andy thinks, this kind of thing feels incredible.

In the end, Andy could only attribute it all to the fact that the "Harry Potter" novels are fairy tales. Fairy tales... no matter how incredible they are, they are understandable.

Thinking about it, Andy fell into a deep sleep.

Early the next morning, when Andy got up, he found that the elective course registration form on the bedside table had disappeared.

After washing up, Andy put on his new wizard robe and went to the Ravenclaw common room.

"Good morning, Hermione."

Andy waved his hand and asked, "How long have you been waiting for me?"

Hermione stood up from the sofa, raised her hands in the air and stretched, "I just got here, less than five minutes ago."

Andy raised his eyebrows slightly, his eyes a little startled.

Hermione in third grade has started to grow.

If Hermione was still a young girl two years ago, then Hermione is already quite pretty now.

It's still a little flat, but Andy has a sharp eye and can see it.

"Huh? What's wrong?" Hermione looked at Andy in surprise.

"It's okay. Let's go! Let's go eat first."

Andy said with a normal expression: "By the way, have you also signed up for all the elective courses?"

"certainly!"

Hermione said: "Divination classes, Arithmetic Divination classes, Ancient Marks, Care of Magical Creatures classes, plus Muggle Studies classes... I'm very interested in them all."

"I know, you want to ask me why I signed up for the Muggle Studies class even though I'm from the Muggle world..."

Before Hermione could finish speaking, Andy smiled and said, "You want to see the Muggle world from a wizard's perspective and see what the differences are."

Hermione nodded and smiled: "That's right! You know me very well!"

"After all, we've known each other for two years," Andy said.

While chatting, Andy and Hermione had already walked to the auditorium.

While eating breakfast, the Ravenclaw prefect suddenly came over. He told Andy that Dumbledore asked Andy and Hermione to go to the headmaster's office.

"Thank you!" Andy nodded.

After breakfast, Andy and Hermione went to the principal's office together.

The principal's office looked the same as before. The circular room looked very spacious, with a desk in the middle with some documents and ornaments scattered on it. Dumbledore sat on the chair behind his desk and winked at Andy.

"Good morning, Professor Dumbledore." Andy and Hermione said politely.

"Good morning, Mr. Collins and Miss Granger."

Dumbledore said: "Please sit down!"

"Why did you come to us?" Andy asked.

Dumbledore looked at Andy, "I think you already know that, don't you?"

Hearing this, Hermione turned to look at Andy and asked curiously: "What is going on? Do you have any secrets?"

Andy touched his nose.

There was obviously no point in pretending in front of Dumbledore, so Andy simply said bluntly: "Professor, are there any other conditions needed to get the time turner?"

"Of course not."

Dumbledore took out two time turners from the drawer - it was a beautiful timepiece with a long and thin gold chain on it.

"What is that?" Hermione asked.

"The time-turner, it can turn back time and take you back in time."

Dumbledore said: "You just need to hang it around your neck, and then turn the timer - remember, turning it once can take you back to an hour ago."

Having said this, Dumbledore crossed his arms, looked at Andy with his blue eyes, and continued: "I hope you can understand that the time turner's capabilities are also limited and very dangerous."

"If you use it with the intention of changing the past, you will gain nothing and may even lose your life."

Andy's face turned dark when he heard this.

How worried do you think you are about me when you say this?

"Of course, I understand!"

Andy quickly assured: "Professor! In fact, I am very taboo about the power of time. If I were not sure that the time turner is safe and harmless, I would not use it at all."

Dumbledore nodded and said in a serious tone: "You must promise me that you will never use the Time Turner for anything other than study, so that I can safely hand it over to you."

"Of course, we promise!" Hermione said quickly.

The little witch's attention has been completely attracted by the time turner.

Back in time!

What a magical power, a magical ability that only appears in movies.

"Professor, if it breaks..." Andy ventured.

Dumbledore's veins twitched on his forehead, "If it is only used for study, the Time Turner will not be damaged."

Andy touched his nose and said, "Studying the time turner...should be considered learning, right?"

Dumbledore felt that he might have thought wrong before!

From Dumbledore's perspective, Andy would never be interested in knowledge other than power.

But this time, Andy signed up for all the elective courses.

Muggle Studies, Care of Magical Creatures... Dumbledore never thought Andy would study these two courses.

Then Andy's purpose is obvious.

He's here to get the time-turner!

Dumbledore originally thought that Andy wanted to use the power of the time turner to change the past or achieve some ulterior purpose.

But now it seems...

Andy may simply want to dismantle the time turner!

"Making a time turner requires very advanced alchemy skills."

Dumbledore said: "In addition, you also need to learn the time reversal spell."

"But this spell has long been lost in the wizarding world."

"In other words, no one can make a time-turner now!"

Andy frowned when he heard this, "Lost? Didn't anyone write it down in a book?"

Damn it, I typed it wrong! This is Chapter 403 (/ω＼)
