Harry Potter’s Strongest Senior

Although Sean knows that the time-time converter is overdrawing the user's future time, but the four-school friendly match is approaching, he doesn't mind overdrawing the future time, and learn some advanced magic first.

However, the time-turner was not as easy to apply for as he thought. After being educated by Snape, he had a deep understanding of the time-turner.

After the last Potions class on Friday, Sean came to Snape's office again. During this time, Sean went to Snape's office quite frequently.

Snape had just returned to the office after class, and seeing Sean following him, he couldn't help but frown. Although he promised Sean that he could come to him with any questions, his character obviously didn't make him a patient and good teacher.

"Grylls, you are such a good student who is diligent and inquisitive, what's the matter?" Snape asked.

"Professor, I always feel that I don't have enough time recently. I have to go to training after class, and I have to learn flying spells at night. If only I had a few more hours a day than others." Sean said with emotion.

"Stop dreaming, if you have time to think about messy things, why not read a book." Snape said without raising his head.

"If there is any magic, it would be great to make me double or turn back time, so that I can learn more." Sean hinted frantically.

Holding the Potions textbook in his hand, Snape suddenly glanced sideways at Sean, then walked towards him, with a pair of gloomy eyes staring at Sean under his curtain-like bangs.

"Did you hear something from somewhere? You should stop thinking about it and go to training if you have nothing to do."

"Professor, I heard that the Ministry of Magic has an alchemy tool called a time-turner, which can turn back time. Is it true?" Sean is bound to interpret the image of a curious baby to the end.

"So you want a time-turner. Do you know how troublesome it is to apply for a time-turner from the Ministry of Magic, how much it costs, and how long you have to wait?" Snape asked Sean three soul-questioning questions.

Sean shook his head. He had no way of inquiring about these details. He even just learned that applying for this thing requires money.

"Is it expensive?" Sean asked sincerely.

"Billed by the hour, ten Galleons per hour, what do you think?" Snape said.

"Professor, is the hour you mentioned the time you hold after you get the Time Converter?" Sean asked suspiciously.

Snape snorted coldly, and looked at Sean as if looking at an idiot, "It's your time to turn back time, you turn back a few hours, and you will be charged the corresponding Galleons in total."

Time is money. This sentence is really suitable here. Hermione should be reimbursed by Professor McGonagall in the name of Hogwarts for Hermione's use of the time-turner. It stands to reason that Sean can do the same.

Sean reckoned that Snape just found it troublesome and didn't want to help him with those complicated applications. Sean suddenly envied the Gryffindor students for having Professor McGonagall's kind and friendly dean.

Sean was persistent. In his impression, this shouldn't be a difficult task. Since Professor McGonagall can apply for a time-turner for Hermione, it's okay if Snape pays attention.

But then Snape taught him coldly, and at the same time popularized science with him about the preciousness of the time-turner and the strict management of it by the Ministry of Magic.

Firstly, the material used to make the time converter is called moon gold, which is produced in Uganda, Africa, and is a magic metal with very little mining.

Moon gold is mined and traded by the government, and the management is extremely strict. Even the supernatural black market has never appeared moon gold. The British Ministry of Magic can only buy a small amount of moon gold from Uganda every year.

The preciousness of raw materials is just the beginning. The time converter involves time and space magic, and an alchemist who is proficient in these two magics is required to melt the magic frame into the time converter.

Alchemists of this level are rare in number, and all of them have made an unbreakable oath with the Ministry of Magic, and they only make Time-Turners for the Ministry of Magic.

There have been no illegal time-turners in the past two centuries, and even in the dark decade of Voldemort's rule, the management of time-turners was still orderly.

The original use of the time converter in the Ministry of Magic was to deal with some accidents, and the time converter can be used to go back in time and investigate the course of the accident, and later evolved into multiple purposes.

These include helping outstanding students, advancing time in the future, and taking a few more elective courses.

Every time the time converter is turned, the time will be reversed for one hour, but Sean only knew after hearing what Snape said that each time converter has an upper limit for the number of times it can be used. If it is turned a thousand times, the magic frame on the converter will be will crash.

"One thousand times means one thousand hours, 41.6 days, and a brand new time converter can only go back 41 days." Sean secretly thought.

"It seems to be about the same. A thousand hours is enough for Hermione for a school year."

Forget it, Sean, Hermione doesn't use the Time-Turner every day, and it only takes one or two hours for her to take elective courses, a thousand hours is more than enough for her, plus Hermione is a very self-disciplined person, except Take classes, and don't use Time-Turner for other things.

In fact, Sean didn't know that Tom Riddle also applied for a time-turner with the help of Horace Slughorn back then. Professor Slughorn, everyone knows that he is especially good to good students eccentricity and care.

"Professor, I think if I have a time-turner, I can learn the flying spell before the forest of the valley begins," Sean said.

"I think you're dreaming." Snape replied angrily.

Sean was worried, who made Snape the Headmaster of Slytherin, in terms of the process, Sean had to apply for Snape in order to be in the queue. The Time-Turner would notify Snape.

"Professor, if you can't learn it, I will bear the 10,000 Galleons myself." Sean made a big bet, and 10,000 Galleons is not a small amount.

Snape sneered, "What do you take on?"

Snape also knew about Sean's financial situation. With his Uncle Hearns' salary, he was reluctant to buy Sean even a new dress.

"Professor, I have no money now, and I will have the money to repay the student loan after I graduate." Sean said confidently.

Sean regards the ten thousand galleons as a student loan, which is actually similar in nature, but in order not to pay the ten thousand galleons, he will redouble his efforts to learn the flying spell.

Snape was soft-hearted again, a kid said that, and he shouldn't go into a corner, arguing about whether he has money or not.

"Okay, you go to training, I will discuss this matter with the headmaster." Snape said impatiently.

When Sean heard this, there was something to be said. Snape's character would not fool the students casually. Now he was waiting for the Time-Turner, but no one knew how long he would have to wait.

The Time Converter is a bug in Harry Potter, and Rowling can't explain it herself. Here I made my own settings, which is simpler.
