Beside the ruins of burning houses, shards of charred wood lay on the floor.

As if it had only been a moment, and as if it had been a long time, the center of the shards of wood all over the ground shook slightly, and then a black head was lifted from underneath.

Clark, who had just been knocked unconscious by the wooden beam, struggled to stand up, touched the back of his head with his hand, and then looked up not far away, just in time to see "himself" picking up the injured Hermione.

"Damn it!"

Clark slammed his fist into the ground in front of him, and twice in a row, he missed the opportunity to rescue Hermione.

To say that it was just a coincidence, he was the first to disbelieve it.

How could there be such a coincidence in the world, as soon as he wanted to save Hermione, he was interrupted by various accidents and missed the opportunity.

It's just that there is less information gathered now, and although Clark has some guesses in his heart, he is not sure yet, and he is ready to try again, and do an experiment first.

Clark got up from the rubble, found a no-man's corner, and turned the time turner again, this time, he turned the time turner three times, ready to go three hours ago.

Once again, the familiar feeling came, and the process was no different from the previous two times.

However, with the increase of Clark's accumulated travel time, the evil consequences of frequent time changes and time travel have gradually brewed and formed in the void.

Relying on his keen perception, coupled with a little insight into time brought about by the prophecy psychic ability, Clark vaguely felt that at the very moment when he used the time turner to shuttle, something was whispering and looking at him greedily in those almost materialized seas of time.

Something that is outside of time, rejected by this universe, is watching him.

These things do not come into contact with life or matter in this universe at any given time, but now Clark feels that as he repeatedly uses the time turner, going back in time, he appears more frequently in the same timeline, and the risk of being exposed to those dangerous beings also increases.

So much so that the protection of this universe for himself in this aspect seems to be weakening, as if some invisible hand is pulling him, making him feel a little heavier in his body.

This little bit of weight is so insignificant, maybe even a fragment of time, less than a thousandth of the mass of an electron, but it's a very bad sign......

So, the barrier between him and these things is being weakened!

At this time, he combined the knowledge he saw in the books in his home collection, and the warning of the professor when he obtained the time turner, and finally came back to a little bit of the taste - time is a constraint for the life in it, but it is also a protection.

It's like a four-dimensional world, although we can decide the fate of the characters in the two-dimensional pictures at will, but once we really want to get in touch with the characters in those pictures, we first have to reduce a part of ourselves to the two-dimensional world, and this process of dimensionality reduction may produce some accidents.

Time also has an impact on those guys.

However, this short shuttle time did not give Clark more time to think, and soon, when Clark landed, he found himself three hours ago, guarding the gate of the Fire Dragon Park with the guards, stopping the werewolves trying to break into the park.

Clark looked at the hot battle scene in the distance, and had no intention of getting involved, nor did he take advantage of the chaos to solve the idea of the werewolf who hurt Hermione.

He just glanced at it from a distance, then turned and walked in the opposite direction, the hill not far away.

Walking up the stairs, carefully dodging Neville and Werewolf Greyback as they fought halfway up the mountain, Clark soon reached the top of the mountain.

At this time, the top of the mountain was empty, and even Charlie didn't know where he had gone, only a kind voice, in the big shed not far away, calling him through a psychic link.

"Clark, you're finally here, what's going on down the mountain?"

Clark heard the eager idea in Nobeta's words, and when he walked into the shed, he saw that the guy had already gotten up and waved his wings, and he was a little eager to fly out.

"It's okay, it's just some clowns." Clark comforted her softly, and kept looking out of the shed, waiting for the arrival of the mysterious black-robed man who controlled Nobeta.

However, Clark waited left and right, and did not wait for the arrival of the mysterious man for half a day...... Then, he suddenly understood that where there was a mysterious person in a black robe, what he saw was himself.

So Clark took the black robe that hung on the wall of the shed, put it over and put it over on Nobetta's back, and gave her orders.

In an excited roar, a dragon and a man spread their wings and soared into the sky.

The wind blew across Clark's cheeks, and on his command, Nobeta quickly flew over the gates of Dragon Park, and then fell from the sky, crushing the gates of the park.

This act of destroying things filled the young Nobeta with the thrill of venting her power, and she roared excitedly, wanting to join the battle against the werewolves.

At this moment, another "Clark" suddenly appeared in front of a man and a dragon.

"How come there are two Clarks?" Nobeta only felt that her small brain was a mess, could this be double the master, double the happiness?

But soon, she felt double the pain, and after the master who appeared after yelling, she and the master on her back began to fight on a spiritual level, and the battlefield was her head.

It was as if there were countless villains chattering in her head, making the dragon upset and manic.

"Enough!"

A dragon groan came out of Nobeta's mouth that only two Clarks could understand, and with a flick of her tail and wings, she deliberately avoided the guards and swept down several werewolves.

The past version of "Clark", who still didn't understand the specific situation, was stunned for a moment, and took advantage of this opportunity, the future Clark, who was riding on Nobeta's back, hurriedly ordered her to take off into the air and fly towards the forest not far away.

A crisp breeze brushed Clarke's cheeks, as if he were driving an open-top Maybach and resting his hand on the window.

There was no doubt in Clark's heart, and after the verification of himself just now, he finally confirmed his guess, that is-

You can go back in time and influence the subsequent development of history, but you can't change what has happened/experienced. Because the world you live in and the things you experience are already the result of being influenced by your future self!

He remembered the time Hermione had forgotten to go to Charms class when she had overslept and had forgotten to go to Charms class and had missed the Happiness Charm.

As a result, after Clark and the others reminded her, Hermione didn't use the time turner to travel back in time and go back to Charms class.

Because Harry and the others did not see Hermione in the Charms class at that time, this has become an established fact, and if you want to change this fact, then in addition to time travel, if you want to change history, you also need to change the memory of everyone in the class at that time, including Professor Flitwick.

So whether Hermione tried it or not, she couldn't change the fact that she hadn't learned the Happy Charm.

And the situation is similar to this incident, but the result is very different, it is the time when Hermione and them save Buckbeak in the original book.

In the original book, Buckbeak, a winged beast with a winged horse, faces the fate of being judged and beheaded by the Ministry of Magic for scratching Malfoy.

And Harry and the others were looking for Hagrid when they happened to see the Ministry of Magic executioner enter Hagrid's room, and they also heard the sound of beheading.

After that, Hermione and Harry used the time turner together, and went back a few hours to save Buckbeak with great ease.

It was only then that they realized that the sound they heard of the chopping of heads was nothing more than the sound of the executioner chopping the stump in a fit of rage.

In this way, all the logic of time is closed, and Buckbeak in the original book was successfully rescued and flew into the distance with Sirius.

After carefully analyzing these two events, combined with the several attempts he had just made to save Hermione, plus some time-related knowledge he had gained from the Godhead fragments, Clark finally had a general understanding of the rules of time unique to the entire Harry Potter world.

Yes, different worlds have different rules of time, but they can be roughly divided into three categories.

The first type is the "fixed timeline", just like the "sacred timeline" shown by Kang the Conqueror in the American drama "Loki", it is a fixed line that extends towards the future, in this timeline, history presents a state of "circulation" and "closure", and the characters' traversal behavior cannot change history.

In this state, the time of this world, or history, itself has a restorative and logical nature, and it forms a fate that people often like to talk about.

Even if the time traveler goes back in time, what they do will not change the future, all events remain on a fixed "timeline", and the actions of the time traveler have become a part of history, and even because of his arrival, these histories that they have seen have been formed.

The world of Harry Potter where Clark is now also falls into this first category.

In the third part, when Harry encounters the Dementor crisis, it is precisely his future self who travels back to save him, forming a "loop", and what Clark has just tried to ride a dragon and meet his past self is also the same operation.

The second type of time rule is the "dynamic timeline", in the world with this kind of timeline, history is also linear, and there is only one, but it can be changed, and the changed history will also affect the future.

The only thing to note is that this effect can be both good and bad for future changes, and it is likely that one of your time crossings will lead to your own disappearance and even future destruction.

There's an old movie called "Crossing the Future" that tells about this situation.

In addition to the above two, the third type of time rule is the "multiverse", or "parallel universe".

In the time and space before Clark traveled, the third phase of Marvel Film and Television focused on the concept of "crazy multiverse", and this point was also first seen in Avengers IV.

For a world set in the "Multiverse", a traveler travels back in time to the past, and a new, divergent timeline is generated on the basis of the original timeline at the first time you change the past.

This is just like in the TV series "Loki", when the female Loki killed Kang the Conqueror, on a "sacred timeline", because no one maintained it, countless branch lines emerged, splitting into infinite parallel universes.

In this case, the time traveler can do anything with impunity in history, because doing so will only split a new timeline.

Of course, the rules of "time" in the heavens and worlds are not so simply divided into three categories, sometimes they are mixed together, and they are effective at the same time, and even occasionally because of some powerful being.

For example, in the Marvel Universe, on the basis of the concept of "multiverse", the concept of "fixed timeline" is also combined.

After understanding these concepts related to "time" and "history", Clark also understands why every time he tries to save Hermione, who is injured by a werewolf, an accident occurs.

Because Harry Potter's time rules are the first type of "fixed timeline", in this world, the history that happened in the past is fixed, and it is the history that cannot be changed by people.

Any attempt to change this history will be affected by the "fate" in the dark, and will lead to failure, so Clark will be discovered and interrupted for the first time, and will be hit on the head by a wood for the second time, resulting in a coma.

In this way, trying to save Hermione from the curse of the werewolves seemed to be wishful thinking.

However, Clark found a loophole in this rule that was not considered a loophole.

Is that the so-called history, really the "real" history?

It's like the incident that saved Buckbeak in the original book, at the beginning, Harry and Hermione heard the sound of beheading, so for them, Buckbeak's beheading is history.

But later, after they traveled through time and rescued Buckbeak, they found out that the fact that Buckbeak was beheaded was not the real "history", they just misunderstood before, and the real "history" was that the stake was cut down.

So you see, a lot of times, a lot of things, what we have witnessed, heard with our own ears, and even experienced ourselves, are not necessarily the truth of the matter.

History, too.

How many traitors and thieves we think are actually loyal ministers and good generals, and how many heroes we talk about are actually despicable villains.

It's like the case of Sirius Black and Peter Pettigrew, who knows what the truth of history is without putting the evidence in front of us, and perhaps before we delve into it, he is both good and bad.

For this, Clark called it the history of Schrödinger.
