Hogwarts: Wizards of Eternity.

Chapter 39: A way to 'cheat' time?

Time is flowing every moment.

But there is no definitive conclusion on what time is. Muggle science has its own definition of time, and wizard magic also has its own understanding of time. Roger knows a little about both theories of time.

Although the principle is not clear enough, Roger does have some practical operation information.

Most of the books that Professor McGonagall lent to Roger were theoretical research and data reports, including an internal research report of the Ministry of Magic that was published long ago.

Roger, who has acquired absolute memory, uses magic to reprint a copy of the book based on his impressions.

Transfiguration is really useful once you master it.

"Summary of Time Travel Experiments, 1899".

In the report, the author from the Department of Mysteries described in detail that no one who had traveled through extremely long time periods in the past had survived.

After many tests by experimenters, the safe limit of time travel is within a few hours.

Of course, this safety is relative.

In fact, it is not that short-term travel is risk-free, but when the journey is too short, the impact you cause will not be amplified too much by the chaotic butterfly effect of long time and space. As long as you don't deliberately make trouble, the possibility of being backlashed by the power of time will be reduced.

At the same time, the Department of Mysteries has verified through experiments that directly casting time and space spells such as the Hour Reversal Spell is not the best choice for time travel.

The release of the spell itself will be affected by the wizard's distracting thoughts. It is okay to release small spells such as the levitation spell, but some tiny errors due to distracting thoughts may not even affect the completion of the spell.

But the time and space spells are different. A slight mistake can lead to a huge error!

The best way to use this kind of unstable magic is to encapsulate the time and space spells into an enchanted object and make it into an alchemical item... Well, the result of their research and development at that time was the time converter.

At the end of the report, the author mentioned the disaster that the Department of Mysteries had caused this year.

In 1899, Eloise Mintab was trapped in the year 1402 for five days. When she returned to the present day, her body had aged five centuries, causing irreparable damage. She died shortly afterwards at St. Mungo's Hospital for Magical Maladies and Injuries.

Not only that, during the five days she traveled through ancient times, she severely disturbed everyone she had ever met, drastically rewriting their lives. At least twenty-five of their descendants disappeared from the present and became people who had never been born.

This is only the consequence that has been observed by the Ministry of Magic. Who knows, because she moved a wooden stake five centuries ago, more Muggles will quietly "disappear" without anyone knowing.

There is no further content in this report.

Because since 1899, ultra-long time and space travel has become a taboo in wizard civilization. There are at least hundreds of legal bans specifically established for time and space travel, and related experiments in the Department of Mysteries have been permanently stopped. This is still the case in 1991, nearly a hundred years later.

...We have to stop. Even a top wizard like Dumbledore can't withstand the attack from the upstream timeline. What if someone suddenly has a brain attack and rewrites the past, destroying the whole world?
Time is so chaotic that sometimes just moving a chair or destroying a horseshoe can completely change the world line.

No one wants to disappear. If anyone dares to play tricks on this, don't blame the world's most powerful wizards and the five Blue Star gangsters who have learned the information for coming to have a heart-to-heart talk with you!
The Ministry of Magic has always been in contact with the British government, and other countries are similar. The Statute of Secrecy applies to most people, and the real upper class of Muggle society has always known about the existence of wizards. While looking at Roger's freshly printed report and listening to Roger's explanation, Harry couldn't help but look back at him: "... According to what you said, reversing time and space to save my parents is simply impossible?!"

Seeing Harry's expression of 'are you kidding me?', Roger smiled and shook his head: "No, on the contrary, the way to salvation is in this report."

"It is known that time travel itself will accelerate the aging of travelers. If we can achieve immortality, wouldn't that mean there will be no such side effect?"

"Changing the established facts of the past will cause unpredictable consequences for the future, so don't change them. Instead, complete your operations in the 'dead corner of time'."

As he spoke, Roger gave an example.

"For example, now your heart has stopped beating and your body has died. This is an established fact that has been observed. If you rewrite it, it will cause the 'world line that continues based on your death' to be destroyed, and time will flow in another unknown direction."

"Then I can take advantage of the 'blind spot in time and space'."

"When I have the ability to reshape the bodies of the dead souls in the future, I will return to this moment, deceive my perception at this moment, take away your soul, and revive you. At the same time, I will completely 'freeze' your body and consciousness in a space gap that I have opened up using space magic, and no one can open it except me."

"I will return to the future, awaken your consciousness after it has been resurrected, and take you out of the 'space-time sealing capsule' called the space gap. During the whole process, I will not change anything in the past, nor will I bring anything from the past to the future, thus minimizing the backlash of time and space."

"Of course, if you really want to practice, the problems you encounter will definitely be more numerous, more complex, and more difficult than the example I gave."

“But it is indeed an idea to solve the problem.”

Roger said to Harry.

Harry's parents' bodies have long decayed and their souls are nowhere to be found. Time travel is indeed the easiest method to resurrect them among many methods.

Harry's pupils lit up for a moment, but then quickly dimmed.

He remembered that his parents were killed by Voldemort. If he wanted to do what Roger said, he must at least be able to hide from Voldemort's perception and do it under his nose.

…Is this possible?
Not to mention immortality which is somehow achievable.

"You don't have to worry about immortality. If I have any results, I will help you get it... Of course, it won't be free."

"You just need to think about how to reverse time and space. This is difficult. You may have a long way to go. It may take hundreds of years."

"But, a little hope is better than no hope, isn't it?"

Roger patted Harry on the shoulder and said, "Anyway, you now have a general understanding of the difficulties involved. If you still want to take this path, come to me tomorrow and I will make a list of books for you."
