Regarding the topic of time retrieval, both Muggles and wizards have conducted quite complex explorations and studies, but in the end, no one has been able to find a conclusion.
As a former Muggle, Maka is not a scientist and does not know Novikov's self-consistency principle and a series of rules about time paradox; but now, as a wizard, he is also far from being able to do so. To the extent that one is exposed to the rules of time, it is even less possible to understand the mysterious and mysterious principles of magic.
Even though he had even met his future self once, even though he had witnessed his future self die in front of him, he still failed to accurately estimate the true horror of the rules of time.
Now holding the time converter in his hand, all he knows is that going back in time will bring a huge burden to people. If the backtracking time exceeds about five hours and twenty-three minutes, the human body will be damaged.
This rule is not a conclusion drawn from some theoretical research, but has been tested by wizards who have used time turners in the past years with their living lives.
If we look at the situation of the future self when we first met, this rule, which has no theoretical basis at all, cannot be ignored at all.
But what can we do with more than five hours
Maka didn't know, but she couldn't allow him to think too much now. He had to use the time-turner immediately. After using it, it was not too late to think about it again.
After putting the four extra converters into his waist pocket, he quickly hung the gold chain of the converter left in his hand around his neck and started to turn the small hourglass in the middle of the golden ring.
The moment Maka started to turn the hourglass, a loud "bang" sound suddenly appeared in his ears, as if someone had struck a gong with enough strength in his ears.
The strong discomfort made him frown immediately, but he did not stop his hands.
As the little hourglass turned, everything around him seemed to be covered with an inexplicable layer of mist. The fog was not thick and had no color, but it made it impossible for him to see anything around him.
And then, when a large number of colorful objects entered his field of vision, he finally understood what the "four-dimensional vision" that his future self had mentioned a little bit was all about.
As time continued to go back, the colorful things that appeared in front of him were also growing and extending... extending from behind him to the front, and then from the front back to behind him, intricately surrounding him, and he There were long, winding things in his eyes.
Maka guessed that those long objects should all be people. That is what human beings look like in the four-dimensional world, the so-called "disgusting worms" in their future self's mouth.
If someone's spatial position at each point in time is fixed, such a scene will form.
But since humans exist like that in the four-dimensional world, what will it look like when I am using the time turner
While he continued to turn the hourglass, he quickly turned his head and took a look.
No, there is nothing behind me. In other words, as a time traveler, I am both free from time constraints and fixed on the original spatial coordinates.
But if this is the case, when the moment comes when he stops turning the hourglass, he will obviously be in a void universe, right
Even though he has not learned any complicated theoretical knowledge, he still knows that the earth is rotating all the time. And it’s not just about rotation, you know, it’s still revolving around the sun!
If you think about it further...
No, before he could continue to think, the hourglass had already turned five times. Maka hurriedly put away the things in her mind, and immediately stopped moving her hands.
Suddenly, his vision shook violently and his whole body twisted. Immediately, he realized that he was no longer in the Time Hall of the Department of Mysteries.
After hurriedly looking around, he discovered that he was standing on a hill near Hogwarts!
"... Was that the feeling of apparating just now?" Maka thought for a moment, then nodded.
Maybe that's right, the whole body twisting at the end should be the phantom transformation spell.
That unpleasant experience is like having the whole person stretched, flattened, and stuffed into a tube. Even if it is not apparation itself, it should be a similar way of moving in space.
After thinking for a moment, he confirmed this and understood that his previous worries were completely unnecessary. What's more, it's not like no one has used the time turner before. He is just imagining it on his own.
Time retrieval does not fix the traveler at a spatial coordinate, but goes backwards as time turns. At the moment when the backtracking ends, the traveler will be moved by the time converter to near his position at that time point, so as to break away from the coordinate point where he was in the past.
After putting aside these messy time and space issues, Maka couldn't help but sigh. Because he discovered that even though he had experienced time travel once, the key points were still missing. It is conceivable that the rules and runes about time are far beyond his reach now.
Is this a secondary rule? No, this is definitely the depth that can only be achieved by those few third-level rule runes.
Although I have a strong desire for this mysterious knowledge, it is obviously not the time to think too much now. It should be already past 4 o'clock in the morning, and in less than four hours, Voldemort and Grindelwald, who is hiding in a floor-to-ceiling round mirror, will follow.
There wasn't much time left for him.
He didn't need to think too much about Voldemort, Grindelwald was the target he wanted to deal with. Even if the opponent never seemed to have any specific malice, he must stop the opponent's actions.
But where Greenwald is now, he has no way of knowing.
Maka, who had a time converter hanging around her neck, could hear a slight but clear sound ringing continuously in her ears. The "click, click, click" kept ringing with clear intervals.
This sound seemed to remind him all the time that time was marching mercilessly towards the terrible future step by step.
What he can currently try to do is to evacuate the people in the castle.
However, as soon as Maka's right leg took a step, her whole body froze immediately. Time passed by second by second, but he was still unable to take the second step.
"...can't pass."
Yes, he can't pass. Because he discovered that if he entered Hogwarts at this point in time, he would definitely be noticed by himself at this point in time.
What would happen if your past self discovered your future self
Maka, who had personally experienced a similar situation, immediately fell into hesitation for a while. He was not sure whether the death of his future self was due to this reason; he was also not sure whether the spherical three-dimensional rune array also had the function of preventing this from happening.
I remember Dumbledore once told Hermione that during time travel, you need to avoid being exposed to the eyes of others as much as possible, especially your past self.
At this moment, Maka couldn't help but feel distressed about her ability to sense magic for the first time.
After he stayed there for more than ten minutes, he deeply realized the difficulty of being a time traveler. A yoke called "rules" has been placed heavily on him, a rule breaker, and he has the illusion of being unable to move forward.
It was only then that he finally realized how hard the old Maka who died in front of him had worked to break this indestructible shackles and come to him.
Now he doesn't even dare to say that he understands something. He just guesses that there must be countless problems that he doesn't understand. In order to solve these problems, he will sacrifice at least his whole life.
After confronting his various fears for a long time, he sighed blankly.
While lamenting that he had been sighing a lot recently, he had no choice but to put the unknown dangers first, and on the premise of avoiding the worst possible situation from happening, he began to plan his next step. road.
There were too many things he didn't understand. Just a time rule was much more complicated and complicated than all the topics he had studied so far. He had to force himself to be extremely cautious.
If you make a mistake and die in the past, nothing can be undone.
Maka looked around again. The snowy night scene and the cold air made him feel refreshed. But no matter how refreshing the environment he was in, he couldn't suppress the boredom in his heart.
After hesitating again for a moment, he simply waved away a piece of snow and sat on the ground.
Not far away was Hogwarts, but he didn't dare to take a step closer there. Endless worries kept him from moving forward time and time again. Even though those worries might be just unnecessary speculations, he still found it difficult to move forward.
"At this moment... I should still be checking the rune array in the front courtyard of the castle, right?" He thought to himself, then shook his head with a wry smile, "It's all in vain."
In this way, Maka pondered for two full hours on the snowy slope near Hogwarts. When a layer of gray light appeared faintly on the top of the mountain to the east, he realized that dawn had arrived unexpectedly.
"In that case, just intercept Grindelwald outside Hogwarts!"
Looking at the castle that gradually became clearer in the field of vision, Maka nodded silently and took out his staff. Counting the time, Dumbledore's funeral will start in a little while.
