This is what Ravenclaw looks like.

"It's a little late, Tyler."

When Andrew handed the book to Hughes and ran all the way over, Professor McGonagall was in the office preparing things for the next class.

"Sorry, Professor, the first class is magic text. I went to look through the magic glyph collection, and I was a little late."

Andrew explained seriously that the professor shouldn't care about this kind of thing.

"Ancient runes, yes, my professor also used that book to lie to me. Later I found that my talent was not in translating those things, but I have to admit, it was indeed interesting."

Professor McGonagall's expression was not nervous. She looked at Andrew with a smile, and there was even a hint of recollection in her expression. "If you need it, you can come over in the afternoon and use the time converter to translate, but I don't recommend that you do it to yourself." Gotta be in such a hurry.”

"Indeed, Miss Granger's class schedule," Andrew sighed, "I feel a little suffocated just looking at it."

"That was her choice, and basically top students in every class will choose to do this, using a Grand Slam certificate to prove their excellence." The professor didn't seem to be disgusted with that choice, "It's just unexpected. Tired, I almost didn’t hold on.”

ah?

That's right, Professor McGonagall was undoubtedly the first - as far as the style of time turner is concerned, it is undoubtedly not new.

"You are different, Taylor. Overexertion is not conducive to your maintaining a good condition in the transformation technique. It's okay if you use it properly, but four hours is too tiring."

"I know very well, Professor, that overexertion will reduce your control over magic and emotions. This is a taboo for transfiguration."

Andrew is not a fool—his body transformation is too late to pursue stability. Excessive use of the time turner or something is asking for trouble.

His current state is actually the best. He just goes to class on time every day, works and rests. In fact, the workload has not increased. It's just that the professor secretly gave him two hours of extra rest time every day.

"Well," the professor nodded, "you must always pay attention to this. Your transformation technique is too strong, which makes it much more difficult to transform the human body."

'Because the strength of your spell is too high, it will be easy for others to fail to save you. Professor, please don't whip the corpse repeatedly...'

Andrew nodded, "Shall I start using it?"

"Don't worry, Taylor. The safest way is to use it when no one is around. You have to find a secluded place - behind the curtain over there, I used transfiguration to create a small space. After I exited the office, 伱Just do what I said that day, remember?”

"I remember, Professor - put it on your neck, twist it twice slowly, and then don't look for yourself in the same time and space, otherwise you will kill yourself."

Andrew recited the content skillfully, and Professor McGonagall nodded.

"Well, let's get started, Taylor."

The professor left and locked the door to the room.

Andrew took out this small thing from the wooden box, then put the chain around his neck according to the instructions, and carefully turned it twice.

The darkness began to disappear, and he felt a strange force pushing him - but he restrained his curiosity and desire to explore, trying not to come into contact with that force, let alone analyzing the rules.

He was carried flying up in confusion until there was a violent tapping sound in his ears.

‘On landing, no, it’s the feet touching the ground. ’

Then he tried hard to stop himself from thinking - Damn it, why didn't he know that he still had such a thirst for discovery?

'Stop. ’

Andrew breathed a sigh of relief, feeling the friction between the gold chain and his neck.

He opened his eyes, and the surroundings were darker - which meant that the sunlight outside the window was no longer irritating.

Obviously, once it succeeds - or this thing can give a student time to transmit for three years without any problems, it is indeed very stable.

He came out of the curtains created by the transfiguration spell, and then looked at the sky - there was no doubt that it was just breakfast time.

‘I’m afraid I’ll have to adjust my pocket watch every day in the future. ’

He glanced at the table - the class schedule had been taken away by him, and the rest of today's work was on the table.

There was no doubt that the professor had been prepared.

'Actually, I can have a little something to eat in the morning...'

He regretted eating too much in the morning - but it didn't matter, let's finish today's work first. There was no homework on the first day of school, and there were no reports from the professor, so work was very leisurely.

He even finished the job in less than an hour.

But he can't go out next - because unlike other students, he really has the possibility of killing himself.

After getting started with the transformation technique, I still studied my own version for a long time - well, a new five-legged monster can be born.

"Review, the next lesson is magic."

Andrew cleared the table and then started to preview. During the summer vacation, he previewed less than half of the book, but reading it again can be regarded as reviewing the past and learning something new.

'Interesting, this seems to work...but you can't cast random spells in Professor McGonagall's office. ’

'In this case, would it be possible if the wand shifted slightly when casting the spell...'

…

"Tyler."

Professor McGonagall's voice rang out, waking Andrew up from his research - strange, the bell didn't ring, and besides, his pocket watch also had a reminder set, so the magic pocket watch function was acceptable.

"Professor, have you finished your class?"

"I left a little early, what should you do next?"

Professor McGonagall put down her book and looked serious.

"Hide until the other me comes after class, and then wait for him to disappear using the time turner to ensure the time loop."

Andrew blurted out - he had been sternly admonished.

"Yes, this is a step you must remember, including closing the door and knocking before you come in, so that there will be enough fault tolerance."

The professor nodded, "I have a separate room on the other side, and you can take shelter in it."

"Yes, Professor."

Andrew didn't listen to the end of get out of class bell and didn't even count the time he had to go to the library.

The best thing to do is to make arrangements in advance - if you are in a hurry or something, it may look cool, but in fact it is just stupid.

He hid in, closed the door, and waited for his other self to visit the professor without any curiosity at all.

'Borrow books from the library and come here...'

Andrew counted the time and then heard a knock on the door.

"Professor, I'm sorry."

"It's a little late, Taylor."

Professor McGonagall said.

"Sorry, Professor, the first class is magic text. I went to look through the magic glyph collection, and I was a little late."

…

Next, he entered the curtain.

Andrew didn't dare to open the door, but he felt the force - but this time he was even more afraid to touch it.

Time begins to cycle.
