Hogwarts passer-by professor

Chapter 204 Time travel again

Yellow sand is everywhere on the plain, and those stone mausoleums are extraordinarily magnificent.

Standing on the top of the pyramid, Eisen could vaguely feel that there was a faint magical aura coming from deeper inside. However, standing at the top of the pyramid, the magical aura seemed to be isolated and no longer flowed outwards.

Looking up at the sky, the sky is cloudless, and the sun is shining directly down, causing the temperature here to rise rapidly.However, none of this can affect Aisen's movements.

With a thought, Aisen turned into light and rushed towards the sky.

Troposphere, stratosphere, mesosphere, warm layer, escape layer.Almost instantly, Eisen rushed out of the atmosphere and entered outer space.

Eisen who turned into light did not stop, but flew straight towards the moon.

There was silence in space, but for Eisen, he felt nothing.Because when he transformed into light, he fell into an extremely quiet situation.

Counting from the moment when Eisen turned into light and flew into the sky to the moment when the moon landed on the back side of the moon, it took less than two seconds in total.

After landing in a meteorite impact crater, Eisen regained his human form and stood on the ground.

Looking at the desolate and lonely moon, even though the moon is the closest satellite to the earth, Eisen could not help but feel lonely.

There is no air on the moon and it is impossible to breathe, which is a big problem for Eisen.But as if the magic effect was solidified on his body before, Aisen felt that he could hold his breath for a long time.

As soon as the idea came to mind, I put a bubble head charm on myself.Eisen found that it had no effect at all.But it's no wonder when you think about it. The effect of the Bubble Charm is to isolate the unpleasant temperatures in certain environments and provide sufficient oxygen underwater.

The reason why it can provide oxygen, whether it is underwater or in other environments, is that oxygen exists.But there is not a trace of oxygen on the moon, so the Bubble Charm is completely useless.

Although he could still spend a lot of time on the moon, Eisen still had his own goals, so he did not waste time.

Using the power of time in his body, Aisen disappeared instantly.

On January 1900, 1, Eisen's figure appeared out of thin air in a crater on the back of the moon.

Looking at the surrounding environment that still hasn't changed at all, Eisen knew that his experiment of time travel on the moon was successful.

only--

If the time is different, the position of the moon should be different.When thinking of this, Aisen was also a little confused.After all, the moon is always orbiting the earth.

He returned from the moon at a certain moment in April 1994 to the moon on January 4, 1900, but the location did not change at all, which is very confusing.

Or is it that the frame of reference only refers to where he is?

After gathering his thoughts, Eisen squatted down and carved an extremely obvious mark on the ground, and cast a firming spell on it to ensure that the mark could be maintained for a long time.

After completing this action, Aisen did not stop and returned directly to modern times.

On the moon at a certain moment in April 1994, Eisen's figure suddenly appeared, as if he had never moved.

After appearing, Aisen squatted down and looked at the place where the traces had been carved.But I found that there was no trace at all.

After taking a look around the carved marks, I saw that the rugged moon surface had not changed much from before.This shows that the surrounding area has not been changed by external forces in the past hundred years.

But the traces that Eisen carved were missing, and the traces that were protected by his magic were missing.

What does this mean?
This shows that Eisen’s changes to the past will automatically be restored to their original state after he returns to the present!Or to put it simply, it's like Eisen has never made those changes in the past.

But how could this happen?Eisen was puzzled by this.

Time passed by second by second, and when Aisen felt a little depressed, he stopped thinking about it for the time being, and turned into light and rushed towards the earth.

More than a second later, Eisen returned to Earth, and then an invisible phantom returned to his office at Hogwarts.

After conjuring a recliner, Eisen lay down and gradually thought about what this experiment represented.

Since some changes in the past will be restored when returning to the present, doesn't it mean that even if he changes history arbitrarily, there will be no problems when he returns to the present?
Do not--

Some previous experiments can only prove that some objects can be restored to their original appearance after being returned to modern times.However, Eisen cannot guarantee the consequences of changes made to characters and real historical events.

It is possible that history will correct itself without causing any changes, but it is also possible that it will be changed beyond recognition.

Therefore, even knowing that changing an item in the past will not affect the future, Eisen still feels that he should be more cautious when traveling through time in the future.

However, if we really go to the experiment, how to grasp one of the degrees is a problem.

Time passed bit by bit, and Aisen was immersed in his own thoughts.

Suddenly, Eisen seemed to have thought of something. He stood up from the recliner, restored it to its original position, and left Hogwarts.

On Charing Cross Street, outside the door of the Leaky Cauldron, the invisible Eisen appeared out of thin air.

Appearing here, Eisen plans to travel through time again.

Seeing that no one could see him on the street with people coming and going, Aisen suddenly sighed.Thinking about it, he was also a member of the crowd before. Fortunately, he awakened the golden finger and was able to see the real side of the world.

With a thought, Eisen's figure disappeared instantly.

On July 1990, 7, Eisen's figure appeared out of thin air at the door of the Leaky Cauldron.After appearing, Eisen did not make any extra moves. Instead, he hid his figure, retreated to the corner of the Leaky Cauldron near the bookstore and waited quietly.

People walked from one side of the street to the other, passing bookstores, record stores, burger shops, and movie theaters, but they just turned a blind eye to the Leaky Cauldron next to it.

Time passed slowly, and when the time came after twelve o'clock, a figure looking left and right appeared in front of Eisen.

If nothing else, it was him who had just resigned.That is, he had just activated the golden finger and left the Emerald Forest Film and Television Company.

Judging from the time, he had just entered a coffee shop in the past, and was trying to create his own "Eight-Nine Mysterious Skills" and "Magic Body Refining Technique" there.

Thinking of this, Eisen couldn't help but smile.Looking at himself in the past, Eisen couldn't help but feel as if he had passed away.

Obviously less than five years have passed, but Aisen feels that a long, long time has passed.

My past self walked slowly over, and was attracted by the Leaky Cauldron Bar. I stopped straight away, glanced back and forth, and then set my sights on the Leaky Cauldron Bar sign.

Then, he seemed to think of something, and a shocked expression appeared on his face.

A moment later, he walked straight into the bookstore next to him. Eisen, who was hiding aside, did not move. Instead, he opened his God's perspective and saw himself in the bookstore talking to the bookstore owner.

A few minutes later, he walked out with a volume of Encyclopedia Britannica in his hand.Before arriving at the door of the Leaky Cauldron, he looked down at his appearance, then smiled, opened the door and walked in.

Aisen, who was hiding aside, nodded slightly and was about to go in and try to make some changes to his whereabouts, but suddenly stopped.

Do you really want to make some changes to your past self?Eisen was still a little hesitant.

Several of his previous time travel experiments showed that he actively changed the state of an object in the past, and after returning to the present, those objects would return to their original state before being changed.It was as if Eisen had not made any changes.

Therefore, during this time travel, Eisen planned to directly intervene in his past self.However, the problem before Eisen is that if he is really interfered with in the past, it may cause some consequences that he cannot bear.

Objects in the past were changed without any impact on the future, but he could not interfere with his past behavior and it would not have any impact on him in the future.

"Be careful, be cautious!" Thinking of the 'code of conduct' he had previously set, Aisen took a deep breath.

Suddenly, Eisen figured it out.Since you want to conduct interference experiments on characters or historical events, you don't need to do it on yourself.In fact, interfering in other people's lives can also achieve your goals.

Furthermore, even if you really want to interfere, you only need to select a target and interfere very slightly.As long as the target's life trajectory changes slightly in the future, it can be proved that interference with characters and historical events can change history.

If the target's future life trajectory does not change at all, then a slightly more obvious intervention is being carried out.If there is still no change at all.

That basically confirms that whether Eisen changes the state of objects in the past or changes the development process of someone or something, he will not change history.
