Wizards are a very closed and conceited group, and for a long time in the past, wizards have walked the world as "gods". Even if the wizarding community is closed for various reasons, this sense of superiority is still clearly reflected.

For example, the term Muggle actually has some derogatory connotations in it.

And this sense of superiority is even more vividly manifested in Muggle studies classes.

Perhaps almost everyone in the ordinary world has imagined what it would be like if they knew magic, which made those wizards born from ordinary families unconsciously assimilated after entering Hogwarts, even if the arguments in the Muggle studies class were very ridiculous in Ike's opinion, but it did not prevent some young wizards from ordinary people from listening to it with relish and nodding from time to time.

Still, there are some merits. At least in Ike's opinion, the most important thing in Muggle studies is what wizards and ordinary people think about the same thing, and how they deal with it.

There's no denying that many things are more convenient to do magically.

But as the saying goes: magic only blooms in a few.

After all, this is not universal, and perhaps one of the reasons why wizards have closed themselves off now.

After the Muggle Studies class was over, Ike ran straight to the hallway on the left side of the fourth floor. didn't have a big grinning past, but put a phantom spell on himself and hid in the innermost part of the corridor.

As soon as he hid, he saw another self hurriedly walk in, pushed open the wooden door and walked in.

In the next second, an inexplicable feeling of exhaustion came up, and after a while, the exhaustion doubled.

"Sure enough, three sections are stronger than one......"

Ike sighed and took a deep breath before walking to the dormitory.

The exhaustion of the accumulation confirms one of Ike's points: the time-turner does not open up new timelines, but rather folds and layers the same timeline.

In a nutshell, every time you use a time converter, you leave a node on the timeline, and it's a point that automatically reads the file. In other words, at the same node, two things will happen, "leaving" and "returning" at the same time. Throughout the timeline, there is only one and only Ike jumping sideways from side to side.

It's like the chorus part of a song is repeated three times, and the song is still the same song, but from Ike's point of view, he hears a song with more chorus on both sides.

Ike himself has a time that has been repeated twice, and can be repeated.

As long as he chooses to use the time converter again.

"It's worth studying......" Touching the time turner in his clothes, Ike felt like he was full of energy, and he was already on fire.

Since there is no such thing as a "parallel time and space", Ike decides to step up. Halfway through, he turned back to the Bing Room on the eighth floor, and used the time turner again to go back two hours earlier, just after the morning Charms class.

It took about 10 minutes to get from the Room of Requirement, which was the time it took for the young wizards to walk from the classroom to the auditorium. Then I pushed the door and left, went straight to the library, found a corner and started writing today's homework.

As he expected, when it came to around 1:50, Ike felt tired again.

This time, it's a bit unbearable. Ike has been studying for more than 250 minutes in a row, more than 4 hours.

Normally, it's time for dinner.

Fortunately, he was prepared.

When he returned to the dormitory, he took out the cockroach pile he had treasured last night, ate a few of them to make him hungry, and then came to the place where he used to sit in the common room, holding a book and reading it quietly.

In the evening, Ike rarely did not go to the forbidden book area. First, it is inappropriate to violate the school rules on the first night of the official class; Second, he was too sleepy.

Learning can make people happy, but "staying up late" can make people tired.

It can also make people bald.

The next day, Friday, Ike's classes were more closely scheduled.

In the morning, there is herbology and transfiguration, in the afternoon there is an arithmetic divination, followed by Defence Against the Dark Arts.

There was nothing to say about herbalism, and Professor Sprout led the group to plant a very ferocious magical plant called "Bargan Bean". When the balgan beans have passed their infancy, if they are not divided into bowls and pots, they will fight each other, and the winner will eat the loser until there is only one left in the pot.

In the process, even wearing dragon skin gloves will risk being bitten and broken, and these brutal magical plants will take off their gloves. Therefore, when the balgan beans are in their juvenile stage, that is, when they have just sprouted, they are divided into pots.

This time is probably next week.

Professor McGonagall was still strict in her Transfiguration class, first checking what had been taught last year and the year before, and after reprimanding a few young wizards who had given her back their knowledge, she began a new lesson.

The difficulty has increased a lot.

In the past, matches were turned into needles, beetles into buttons, etc., but the shape and nature of the changes were just changes, but this year the size and quality have changed.

One person gave a button and turned them into a rat the size of a palm......

Without exception, even Ike overturned in this class. Until the end of class, Ike was only able to turn a button into a mouse, but it was still the weight of a button.

The afternoon arithmetic divination is arguably the least magical class at Hogwarts. This method of divination, which originated in ancient Greece, only requires a piece of paper, a pen and the ability to spell, add and subtract, and is very scientific and materialistic.

Unlike divination lessons, arithmetic divination requires the memorization of a large number of words, all of which mean and symbolize each number in different divination questions. You must know that arithmetic divination has a history of more than 2,000 years, and I don't know how many divination problems have arisen in such a long time, and each question must be written down with the symbol of each of the nine numbers from 1 to 9.

Just by looking at the list of required reading books for the third grade sent by Victor, the professor of arithmetic and divination class, Ike felt a little bald on the top of his head.

But happily, arithmetic divination is not very difficult. Following Professor Victor's rhythm, Ike only tried it slightly, and the words "Arithmetic Divination LV1 has been learned" appeared on the waste notebook system.

It's really a typical easy to get started and hard to master.

After finishing his arithmetic divination lesson, Ike went straight to the Defence Against the Dark Arts classroom on the fourth floor.

The classroom was already full at this point, but no one seemed to be expecting what Professor Lupin would teach everyone.

The painful experience of the first two years made almost everyone not hope much about it, after all, Hogwarts' Defence Against the Dark Arts class was notoriously unreliable, and the whole of Europe was notorious.

Ignoring the speculation of Stewart and the others on the side, Lupin would make a fool of himself in front of everyone, and Ike wondered if this lesson would face Boggart as he remembered.

And what will you be most afraid of?
