Hogwarts: Wizards of Eternity.

Chapter 79 The Savior's Time Magic
Time is a very wonderful thing. The more you need it, the faster it passes. The more you hate it, the slower it passes.

For those who love magic, they simply want to devote all their time to it. But in the eyes of little wizards who are not so interested in magic, magic is just math and English with a different name, the same obscure theory and the torturous word count homework.

For Roger, time passed quickly during the experiment, and it also passed quickly for the students who had finally had a holiday to go home and play for more than ten days.

In the blink of an eye, it was January and Hogwarts started again.

This not only means the beginning of the second half of the semester, but also means that Harry Potter is finally about to begin his magical journey!

In the first half of the semester, Harry initially devoted his spare time to Quidditch training. After the Quidditch preliminaries, he had a long talk with Roger, which turned into experiencing the memories of his parents.

After that, he faced Snape, learned who Voldemort was, borrowed a second brain from Roger, began special combat training with Snape, and finally faced Voldemort with Snape on Christmas Eve with the determination to die.

Roger thought that Harry had been like a bow that was constantly being pulled over the past six months, with the string stretched too tight.

Cultivation requires a balance between relaxation and tension, and this state is not suitable for learning extremely sophisticated magic such as time.

So even though Harry wanted to study, Roger still gave him a holiday and told him to wait until school started.

That is now.

"Roger, I've finished reading the book you lent me yesterday." In the common room, Harry walked to Roger's side, returned an ancient booklet to Roger with a painful look on his face, and handed him a piece of parchment along with it.

This piece of parchment was the homework assigned to him by Roger to test his mastery of time theory.

Although Harry didn't hate magic, time magic was completely different from ordinary magic. Those extremely obscure theories and time laws that violated common sense really gave him a headache to learn.

Roger's exam was not an ordinary class assignment where he could just copy a few sentences from the book to get by. What he wrote down had to be what Harry fully understood and learned.

Time magic is such a dangerous thing that you cannot be careless with it.

"Let me see." Roger took the booklet he borrowed from the restricted area, put it aside, and looked at the parchment.

After taking a look, Roger smiled and said, "Not bad."

"Now that you have reached this point, I can teach you the time spell."

Magic is a miracle of the mind. The most important thing when using magic is belief and determination.

If you have no idea what time is, how can you believe it and be determined to make sure that your casting is correct?
Now that Harry had passed his initial test, Roger could teach him the 'practical' stuff.

"Time spell?!" Harry exclaimed in surprise.

During this period, he not only studied the theory of time magic, but also learned a lot about the control of time magic by the international wizarding society and the Ministry of Magic.

Not to mention the problem of how to obtain time magic under the Ministry of Magic's strict control over it, even the random use of time magic is not allowed by law!

Harry thought that he would have to carry out virtual calculations like the theoretical physicists in the Muggle society, and it would take a long time before he could...

Seeing why Harry had this expression, Roger patted him on the shoulder: "Don't worry, there won't be any risks here."

"First, this spell is one I created myself. It does not involve any classified information."

"Secondly, this magic does not involve changing the past. It is purely used to familiarize you with time magic, so it will not violate relevant laws."

"Finally, the spell itself is very safe. Even if you make a mistake when using it, there won't be any serious consequences... probably."

Although Harry had agreed with himself that he would study time magic for himself.

But with Harry's magical background, if he was left to slowly explore on his own, who knows when he would be able to achieve results. So Roger's plan was to help Harry for a while and guide him into the field.

After crossing the difficult entry threshold, when Harry is capable of conducting research on his own, I can let him grow wildly.

"I see." Harry breathed a sigh of relief when he heard Roger say that.

Now he has a better understanding of time, but if Roger takes out the time magic of the 'Hour Reversal Spell', he will not be able to perform it. Harry still has this self-knowledge.

Then, Roger drew out his wand and began teaching time magic in the common room as if no one was around.

Anyway, I have already told Dumbledore that Harry wants to use the Way of Time, so there is no need to keep it secret. As for whether teaching directly here will lead to others learning magic...

If a young wizard who had never received any relevant training could learn his magic just by listening to some of his explanations, Roger would only be surprised!
Found another genius who is suitable for harvesting... ahem, suitable for studying magic together!
Placing his wand on the parchment Harry brought, Roger chanted his own spell: "Time Cinema!"

The next moment, a white light appeared on the parchment, and then a large amount of film, like the ones used in old-fashioned movie theaters, floated into the air with magical light and hovered above the common room.

Roger held the wand over the reels of film that were being drawn out.

Then, everyone in the room saw how this parchment was produced, how it was sent to Hogwarts, and Harry's crazy expression as he scratched his ears and looked like he was writing his understanding of time on this parchment in the library.

"The effect of this magic is very simple. You can extract the 'past image' of the target and project it." Roger's explanation sounded.

The Time Cinema Spell originated from a sudden idea that Roger had when he was studying prophecy and time magic.

In addition to the premonition of crisis, Roger also learned some other ways of prophecy at Hogwarts, but they were far less powerful than his prophetic ability.

Only divination in the past tense is acceptable, but it is not 100% accurate.

Originally, Roger did not take this matter to heart. After all, the crisis premonition was enough, and he did not force other predictive abilities.

Instead of investing energy in a field where the marginal diminishing returns are too high, it is better to study more about the theory of three-dimensionality.

It was not until he was preparing lessons for Harry that he suddenly remembered this.

"Can I combine prophecy with time and create a magic that allows me to directly view the past?"

Roger tried it, and direct live broadcast viewing didn't work. But after adding a 'medium', the magic actually worked!

...In fact, to be precise, it is not impossible to directly watch the past time and space, but the difficulty of casting the spell is dozens of times more difficult than the method of extracting the "time film" of the object of the spell and projecting it.

Anyway, it was impossible for Roger to do it with his not-so-high attainments in time magic. The fact that he was able to complete the development of the Time Cinema Spell was largely due to his foundation in prophetic magic.

Fortunately, developing magic is not as difficult as using magic, otherwise Roger would not have used this magic to help Harry get started.

When Roger was explaining.

Seeing this new magic that they had never seen before, many little wizards in the common room came up to Roger with curiosity in their eyes and listened together.

But there were also some older male and female senior wizards who were originally very interested, but for some reason, they suddenly grabbed their clothes, looked with horror at Harry Potter who was being taught by Roger how to use this magic, and couldn't help but take a few steps back.

Roger, who was explaining, also saw their appearance, but didn't care.

It is normal for young boys and girls who are different from innocent children and have their own little secrets to be afraid of this kind of magic that can check your "browser history" at will.

Of course, this is just a metaphor. It is now 1992. Google search engine appeared in 1998, and Baidu was born in 2000. We have not yet entered the era of information explosion.

Amid the surprise of the younger students and the fear of the older students, Roger quickly finished teaching Harry.

The Time Cinema Spell is the type that is easy for those who know it, but difficult for those who don't. For someone like Harry who has some theoretical knowledge of time magic, it is not difficult.

Swish!
Watching the time film bloom under Harry's wand, Roger nodded with satisfaction, and then reminded: "You can use this time theater spell to familiarize yourself with time magic, but it's best not to use it on other people's personal belongings."

"Okay, I remember that." Roger noticed the abnormality of some people around him, and Harry naturally noticed it too.

After finishing his teaching, Roger stood up and left the common room, taking the quaint booklet with him. It was a book borrowed from the library and he had to return it after use.

But just as he was on his way to the library, someone stopped him.

"Roger, I want to discuss something with you."

The tall figure stood in front of Roger, and Roger saw a rare restraint on his familiar face.

"What's the matter, Headmaster Dumbledore?" Roger felt a little curious. There were not many things that could make Dumbledore show such an expression.

"It's about... Grindelwald." After hesitating for a long time, Dumbledore finally said the name!
