Hogwarts Passer-By Professor

"What spell?" Glancing at Ron, Eisen nodded at Harry, gesturing for him to continue.

"I just wanted to hear Dumbledore say 'astral projection', and then I fell asleep—" Harry said with a puzzled look on his face.

"Astral projection - what kind of spell is this?" Ron showed a surprised expression, and even Hermione next to him looked at Eisen expectantly, waiting for his explanation.

"Astral projection?" Eisen's face was startled, but his mouth began to mutter.

"Professor Eisen, is there something wrong with this spell?" Seeing Professor Eisen's gesture, Harry couldn't help but speak.

"Oh, of course it's okay, Dumbledore won't hurt you." His thoughts were interrupted, and Eisen didn't show any abnormal expression. After he said something, he continued to ask: "Did you feel any way after you woke up that day?"

"Well——, I don't know what's going on, I feel very relaxed." Harry recalled the feeling at that time, "Yes, and I slept very comfortingly that night, and my spirits were very good the next day."

"It must have been the night Professor Lupine left Hogwarts!" Recalling that Harry's face was indeed radiant that day, Eisen nodded thoughtfully.

"I remembered, you were indeed different that day!" Ron looked at Harry in surprise.

"That's right, after Professor Lupine left, I wasn't in a good mood, I thought I couldn't sleep well, but I slept well that night—" Harry said softly.

astral projection --

Could it be that Dumbledore has already solved the problem of Voldemort's soul fragment in Harry? Such thoughts popped up in Eisen's mind uncontrollably.

If that was the case, wouldn't it mean that Voldemort had only one Horcrux left, Hufflepuff's golden cup intact.

In other words, if Eisen sneaks into Gringotts and destroys Hufflepuff's golden cup, Voldemort is basically done for.

Tsk tsk, this Dumbledore really deserves to be the greatest wizard of our time, if he doesn't make a move, he solves a big problem directly.

But, why didn't he tell himself? Thinking of this, Eisen couldn't help showing a strange look on his face.

However, if Voldemort's Horcruxes were all destroyed, there was a question that made Eisen curious. That is whether Voldemort's remnant soul will continue to exist, or it will simply dissipate.

Of course, before talking about this, it must be clear that the reason why Voldemort's remnant soul can exist without the body and escape to the Albanian forest to parasitize animals is because the Horcrux still exists.

Moreover, Voldemort was parasitic on animals, and he was able to maintain his consciousness for more than ten years. Obviously, this is also the credit of the Horcrux.

So, back to the previous question. If all of Voldemort's Horcruxes were destroyed. Will his remnant soul hidden in the Albanian forest dissipate out of thin air without the support of the Horcrux?

Or, because the remnant soul is parasitic on animals, even without the Horcrux, his remnant soul can still survive!

In other words, without the support of the Horcrux, although Voldemort's remnant soul can parasitize on animals, it cannot maintain a clear consciousness. Just like Nagini who was under the blood curse, his consciousness was gradually wiped out?

Thinking of all the guesses, Eisen shook his head slightly, but he couldn't hide the smile on his lips.

"Harry, did Professor Trelawney make any predictions during the Divination exam?" Eisen asked with a flash of inspiration.

"Professor Trelawney? No prophecy!" Harry froze for a moment, then shook his head.

Eisen nodded and fell into thought again.

He vaguely remembered that according to the original plot, Trelawney actually made a prophecy in front of Harry during the divination class exam. The content of the prophecy can be summed up as follows: Peter Pettigrew will find Voldemort and help him rise again.

But now it is obviously impossible to have this prophecy anymore.

After all, Pettigrew has been imprisoned in Azkaban. Then, of course, Voldemort's remnant soul will continue to live in the Albanian forest.

What an unrecognizable plot! Sighing like this, Eisen restrained his divergent thoughts and stopped thinking about it.

"Professor Eisen, goodbye!"

"Goodbye, professor!"

...

After dinner, Harry and Ron, as well as Hermione, said hello and goodbye to Eisen.

Afterwards, the trio left Hogwarts Castle and boarded the Hogwarts Express.

The trio went back to their respective homes, while Eisen continued his book moving business in the library. Recently, Eisen's Oneiroi spell has been continuously cast, and the power accumulated in the dream world has become more and more sufficient, but it seems almost meaningless to have a qualitative change.

In this regard, Eisen was not in a hurry, but just waited quietly.

On this day, when flipping through books in the library, Eisen was a little absent-minded, always feeling that something was overlooked by him. After several struggles, Eisen simply left the library and went directly to the secret base.

Feeling the chilly environment around him, Eisen's mood went through, a flash of inspiration flashed in his mind, and he suddenly thought of what he had overlooked.

astral projection --

Before the trio left Hogwarts, something Harry had said resurfaced in Eisen's mind, and then he came up with the term "astral projection".

"But——, is there anything strange about astral projection?" Eisen sat straight on the chair behind the long table in the alchemy laboratory, and then muttered.

"Astral projection, a new spell created by Dumbledore, can knock Harry's soul out of his body, and then solve the problem of Voldemort's soul fragments—no, not this one!"

"The function of astral projection, the power of astral projection...the principle of astral projection—the source!"

"The source, that's right - the creative source or function of astral projection was used by Marvel's supreme mage Ancient One to travel the multiverse! Multiverse - parallel world!"

Eisen stood up abruptly, his eyes flashed brightly, and he suddenly thought of something.

"Parallel world?" Eisen started pacing in the open space of the laboratory. "Could it be that I used the time travel feature to go back to the past. Before 1972, I really went back to the past. And before 1972, I actually went to the parallel world." world?"

When he came to this conclusion, Eisen was a little shocked for a moment.

After thinking about it for a long time, Eisen realized that if nothing unexpected happened, it should be true. This also explains why none of the changes he made before 1972 would have any impact now.

Because the changes in the parallel world must not affect the world where Eisen is now. After 1972, it is the past of Eisen's world, so some changes made can affect the present.

wait--

Eisen suddenly thought of something. He remembered very well from his previous time-travel experiments that some of the changes he made in 1901 seemed to show no signs of change in 1902.

If it's just a parallel world, then how can this be explained!

Eisen continued to meditate, his brows furrowed unconsciously. After a while, Eisen frowned slightly, as if thinking of something.

"Unless—every time I return to the past before 1972, I actually enter a brand new parallel world!" Eisen was shocked by the conclusion he drew, "This is the multiverse???"

[To be honest, I have been using Yeguo to read and read books recently, change sources, and read aloud with many timbres, yeguoyuedu Android and Apple are all available. 】

For a moment, Eisen felt that his mind was full of blood, and he was in a daze.

After a long time, Eisen stopped pacing and continued to sit down.

But when it comes to time travel and parallel worlds, I still don't understand it. Well, if you want to talk about multiverses or parallel worlds, it is reasonable to say that there is no problem.

After all, Eisen has been directly reborn in this world through time travel, so it is not incomprehensible to add the concepts of parallel worlds and multiverses.

But the problem is, the time-traveling characteristic integrated in Eisen, even though the grade has reached the legendary level, is only a time-traveling characteristic. How could he travel to another parallel world out of thin air?

Eisen can still understand if time travels, but time travel makes Eisen feel a little strange.

After thinking about it for a long time, Eisen couldn't figure out what was going on, so he could only blame it on his Gold Finger.

"Perhaps, Gold Finger already existed at the moment I was born, and it was only activated when I went to work after the age of eighteen." Such a thought suddenly appeared in Eisen's mind, which made him a little dazed.
