Hogwarts Passer-By Professor

After thinking about these things, Eisen breathed a sigh of relief.

After all, if it's okay to interfere with his past behavior and not change history, then there will be no problems with Eisen now.

But once the history is really changed, it is hard to say whether the current memory of Eisen will change or not, even if he exists or not.

Thinking of his time travel behavior this time, Eisen suddenly felt that he was still a little reckless. He only focused on experimenting, but he didn't think that time was still a mysterious force for him.

With God's perspective fully open, Eisen's gaze has turned from the Leaky Cauldron to Diagon Alley.

Obviously, he has officially entered the wizarding world in the past. Next, enter Gringotts to exchange money, and then enter Ollivander's wand shop to buy a wand.

After withdrawing his gaze and changing the normal perspective, Eisen planned to go back.

However, before returning, Eisen stopped in his heart. Then, he cast magic spells such as confusion spells and concealment spells on his past self.

For a full five minutes, Eisen mobilized all the magic power in his body to cast these spells.

When Eisen stopped his movements, a little inexplicable expression appeared on his face, and a rather complicated light shone in his eyes.

For Eisen, he remembers very clearly that after he first entered the wizarding world, he has always set himself up as a Muggle-born wizard, and has lived in the Muggle world for a long time, and has been studying the life and habits of Muggles, etc. .

But if someone really looked into it carefully, he would definitely be able to find out all his origins.

At that time, after Eisen entered Hogwarts, he didn't pay much attention to his origin. One is that I don’t think there is anything to worry about, and the other is that I have confidence in the growth rate of my own strength.

So I don't care at all.

The purpose of casting spells on myself like this just now is to confuse and hide my "following feet". In this way, when others check his details, they will only find out the information that Eisen has spread—that is, a wild Muggle-born wizard.

If you continue to investigate in depth, you will be confused by the magic on him and get over it.

At this moment, Eisen even suspected that he could stay safely in Hogwarts all this time, maybe it was because he had cast a spell on himself.

Otherwise, how could no one go to investigate his details? Especially the Ministry of Magic and the Hogwarts Council. Wouldn't these institutions investigate a wizard of unknown origin and make him a professor of astronomy in the school?

Obviously, this should be unlikely.

There is a high probability that his "heel" has been imitated by his own spells, so that those who investigate him come to the conclusion that he is a Muggle-born wizard with a very clean history.

If the investigation ends here, then naturally there is nothing wrong with Eisen.

Although I don't know if this is true, but Eisen thinks it should be close. After all, with Eisen's current strength to cast spells, he is really confident that almost everyone will not be able to find out more information about him.

After trying to understand these things, Eisen didn't know what to say for a while. Take a closer look at your own situation. I didn't think about it before, and I didn't find anything.

But now, under his full concentration, he also felt that his name seemed to have faint traces of magic. But the effect seems to have evolved a lot after the baptism of time.

I only have a vague feeling that it does have effects such as expulsion, confusion, and anti-tracking.

Hey—wait—

Eisen's face froze suddenly, feeling that things were not that simple.

Because he suddenly thought of a question, that is, after casting a few spells on his past self, has history changed?

If history has changed, it seems that it has. Because now he suddenly found that he could feel some traces of magic from his name.

But it seems to be reasonable to say that history has not changed, because this is how history develops from the past to the future. Eisen's action of casting spells on himself may have evolved in this way in history.

After thinking about it for a long time, Eisen only felt a little pain in his head, and finally had to sigh the magic of time.

Sighing slightly, Eisen walked to the door of the bookstore next to the Leaky Cauldron. Then, on the floor tiles on the side of the door steps close to the Leaky Cauldron Bar, the trace of "∞" was carved.

After that, Eisen activated the power in his body and disappeared in place in an instant.

In April 1994, Eisen appeared in front of the Leaky Cauldron in an instant. Apparently, Eisen has come back from 1990 to the present.

After hiding his figure and squatting in the corner, Eisen waited quietly. A minute later, Eisen let out a long breath, not feeling the backlash from time.

Looking around, there were still people coming and going, which made Eisen feel a sense of intimacy for no reason.

With a thought in mind, Eisen walked to the door of the bookstore next to the Leaky Cauldron, and saw the clearly visible imprint of "∞" on the stone steps near the Leaky Cauldron.

Apparently, such imprints haven't disappeared - huh? Didn't disappear?

Eisen stared at it with wide-eyed eyes, then stretched out his hand to caress over the mark.

The imprint is indeed still there, but——this is unreasonable!

For a while, Eisen felt a little confused.

Previously, Eisen had tried several times. He obviously changed some objects in the past, but after returning to the present, he would find that the state of those objects changed by him would return to the state before they were not changed.

This is true of the Egyptian pyramids, even on the moon. How come this time, the changed state will always exist?

Is this where the problem arises? For a moment, Eisen's mind seemed to be filled with slurry, and he almost couldn't think.

Looking up at the sky, the sky in London is clear, with the slightest breeze blowing, it should be a beautiful day. But I don't know if it's the influence of psychological effects, but Eisen always feels a little weird.

Could it be that some evil god, outer god, or master of the restraining system invaded this world and brought strange changes to this world?

hiss--

Eisen almost gasped.

"Thinking too much—thinking too much—calm—calm—" Eisen cooed, trying to calm himself down.

A few minutes later, after Eisen calmed down, he began to think about the difference between this time travel and the previous times.

different location?

That's for sure, but it shouldn't have much to do with Eisen's problems.

If not, then is the time difference?

Eisen understands that the time travel back to the past is a little different these few times.

For example, the first two times, whether it was the traces left on the Egyptian pyramids or the traces left on the moon, the time was in 1900.

Only the imprint left near the Leaky Cauldron this time was in 1990.

But—this doesn't seem to make sense logically.

There is no reason why the traces left in 1900 will disappear after returning to the present, and the traces left in 1990 will remain after returning to the present.

This—is there any reason for this tm! It's neither science nor magic okay! Eisen scratched his head, feeling that the lake of pulp in his head seemed to be churning again.

Time passed slowly, and suddenly, Eisen's face changed as if he suddenly remembered something.

"It's okay, it's okay——" Eisen looked rejoiced, and began to mutter something continuously.

It suddenly occurred to him that returning to the traces left by 1990 and returning to the present is still preserved, which means that history has indeed changed.

But in doing so, Eisen is grateful for being cautious. Otherwise, wouldn't he almost really change his own past?

With a certain mind, Eisen then flashed back to Hogwarts directly.

Sitting in a chair behind his desk, Eisen began to reflect on the conclusions he had reached through time travel.

The conclusion is that the changes made by Eisen back in 1990 and back in 1900 have a very different impact on the present time.

However, there is one problem that Eisen needs to determine at present. That is, only by going back to the time nodes of these two years, the results of the changes are different, or is it the same in other years!

Obviously, this is indeed the key to Eisen's determination at the moment. If this problem is not resolved, then the next actions will not be easy to carry out.

Thinking in this way, Eisen disappeared from the office again in a flash, and started his own experiment.
