Can I say that Philnet in this article is actually my dish?

Although it's a mouthless and introverted sullen personality, it's unexpectedly a gentle and good man. I'm the most disgusted with this kind of loyal dog man, cheek support...... (Crowd: You're enough!) ）

Holy Grail 2 (Positive): Understood

、

Hogwarts, England

、

After confirming the time period he was in, Opal immediately found a hidden corner and turned into a unicorn form, and rushed towards the centaur garrison in the Forbidden Forest.

During this time, in order to help Riddle find the information he wanted, Opal was almost crazy and devoured a lot of books on the principles of magic on his own, thanks to the generosity of the centaurs and Sensa Qianwei.

Perhaps because she already had the relationship of "Son of Gaia", the understanding of those difficult and complex magical principles was something that Opal could understand with a little concentration.

On this basis, Opal easily understood the principle and truth of the so-called "time return device".

The so-called time-turner is actually a small-scale leaping magic built on a network of timelines - jumping from a point in time in one world to a specific point in time in another world.

Strictly speaking, this is not a time magic, but should belong to the category of space magic.

In other words, after using the Time Returner, the user enters another parallel world that is derived at the same node due to the opportunity of "using the Time Returner" - although everything in this world is in the same vein as the original world, and then through another "choice" opportunity, he returns to the parallel world that originally belonged to him to continue his story.

Theoretically, being able to go back in time means that you can predict the future.

If you have a time returner, you can indeed achieve some degree of "foresight" - for example, Opal at this moment knows exactly what is about to happen.

Therefore, the indiscriminate use of the time-return device will cause many things to be unpredictable and complicated, and if you use the time-return device to tamper with the past at will, it will definitely lead to the collapse of the history of a world - so it can be judged from this point alone that the use of the time-return device should have its limitations.

After all, Opal didn't think that Qianwei-senpai would deceive herself about the laws of this world - "space-time uniqueness", which means that there will never be two identical individuals at the same time period.

In other words, although the "world" that uses the time-return device and the "world" that does not use the time-return device are in the same vein from the perspective of time and space, the individuals in the space are fundamentally different.

Therefore, when using the time returner, the first time frame for returning is a limit - the time limit of 12 hours before and after, which is to prevent the world from detecting the distortion of time and space and make independent corrections.

The second is the things that can be "predicted" by using the time return device and the things that can be interfered with - from the current situation, the preliminary inference that can be passed on to oneself in the past should only be some abstract things such as knowledge, information, and passwords, which will not disappear after being given; However, the physical object cannot be transmitted by the time-return device - that is, the time-return device cannot be used to reproduce the physical object.

In addition, even if you go back to the past, your physical condition is still "future" - that is, if you use the time returner frequently without taking coagulants, it is very likely that the result will be an overdraft of energy and a shortening of lifespan, which means that "others have only lived one day and your body has experienced XX days later".

However, the current self is only rewinding 12 hours ago, and this level of overdraft is still within the tolerable range.

It's just that if you need to use the time returner again in the future, you must first configure the coagulant - fortunately, most of the coagulant materials can be found in the Forbidden Forest, and a small number of special materials can also be obtained if you go to the secret realm of the lake.

However, these are only Opal's own speculations at the moment, and some things need to be verified by herself.

Biting his lip, Opal shook his head and forced himself not to think about what was there or not, and landed lightly on the centaur station.

"Miss Opal? How did you end up here at this time? ”

Bennas, who was in charge of patrolling the village, hurriedly saluted.

[I have something to look for, is it here?] ]

In the blink of an eye, Opal returned to his human form.

"His Highness Opal? Why did you come here so early today? No notice is given. ”

Just as Bennas was about to answer, Fei Leng Cui, who came out of his room because he sensed the commotion, showed a look of surprise.

[There's no time to say anything superfluous now, is Mr. Thestrals still resting in the old place?] ]

Recalling the previous events, Opal's tone was a little eager at the moment.

"What's going on, Your Highness Opal, it looks like you're in trouble."

Fei Leng Cui's brow furrowed, and he put his hand on her shoulder and patted her gently, signaling her to calm down.

[Hmm...... It's that I'm a little anxious......]

Opar, who sensed that his condition was wrong, closed his eyes and took a deep breath, then gathered his thoughts, [Do you remember the half-giant who lives on the edge of the Forbidden Forest? ]

"That Hagrid, who always does bad things with good intentions?"

Fei Leng Cui tilted his head, "Although he has the blood of a giant, he is still a big guy who is more popular with animals. Could it be that something is wrong with him? ”

[Good intentions do bad things?] Very apt evaluation. ]

Opal put a black line on his head, [Actually, that's why I'm here this time.] ]

"Did he keep any more dangerous breeds?"

Fei Leng Cui frowned, "Actually, is it more serious than Arago, the eight-eyed spider?" ”

[I don't want to say that, but ...... I think it's probably more serious than that. After all, now that the eight-eyed spider has signed a contract with me, there will be no danger. ]

Speaking of this, Opal couldn't help but smile bitterly, [Do you know...... He's hatching a dragon? ]

"Dragon?!"

At this moment, a roar belonging to a dragon in the distance made all the centaurs present change their faces, "Why is there a dragon still here?" ”

[That's why I said it's serious!] ]

Opal sighed, [I'm here to inform you of this, and now I must go back to the castle first.] Then Mr. Thestrals, please let you know. ]

"Okay, I know what to do."

After exchanging a look, Bennas immediately ran in the other direction.

When Opal tried to change back into unicorn form, he was a little stunned to find that he couldn't change his form.

Counting the time, she should have turned into a unicorn and headed to Hagrid's cabin at this time, right?

Other words...... In the case of the human form, "now" and "future" can coexist, while in the unicorn form, there can only be "one" of the two?

"What's wrong with you, Your Highness Opal?"

Fei Lengcui was keenly aware of the difference in Opal's expression, and said with concern.

[I think...... You may need to send me to Hogwarts as soon as possible. ]

Rubbing his temples, Opal smiled bitterly again, [Actually, I was able to stand here at this time after using the Time Returner, and the real me at this time should be at Hagrid's house at the edge of the Forbidden Forest.] ]

"So you ...... now"

[I don't know why, but it's clear that there is only one person who can transform into a unicorn.] ]

"In that case......

Emerald bent down and took Opal to her back and sat her around her, "Hold on. ”

[Excuse me.] ]

Glancing in the direction Benas had left, Opal let out a sigh, [Hopefully Benas can notify Mr. Thestrals.] Otherwise, the rest of the matter will be really difficult to handle. ]

"Don't worry."

As if to understand Opal's concerns, Fei Leng Emerald turned her head and smiled at her, "We won't let you down. ”

[Ahh......h

I can only say that I hope so.

===================I'm =============== the dividing line of the switching scene

Hogwarts Forest Warden's Hut

、

Sitting on the body of Philant, he passed through the forest path and went around to the other side of the castle, and after bidding farewell to him, Opal immediately rushed towards the area where the intense pressure was erupting.

In fact, she originally wanted to rush directly from the Forbidden Forest, but before she could get close to the edge of the forest, she found that if she went from that side, she would pass through the territory of Arago, the eight-eyed spider - although she had concluded an equal contract with him, it was only for Arago himself, and Arago had many children in that area, and the danger of forcing her way through was too high.

Of course, Opal doesn't think it's just a coincidence.

Now it seems that the third limitation of the time-return device lies in this - although the use of the time-return device can go back to the past, it cannot change the "history" that has happened, and any attempt to change history is not allowed.

And what she has to do now is to push history forward in the direction she knows based on the actions made by the "human self" in her memory.

With this in mind, Opal saw himself in unicorn form as he competed with the female Norwegian Ridgeback Dragon.

[LingRan, Alison, in the name of Natural Gaia, stop!] ]

After reading the words in his memory, Opal watched as the figures chasing each other in the air immediately stopped as if they had pressed the stop button.

Real Name...... Is it?

In that case, Ling Ran is indeed hers...... Real name? It seems that she really hasn't completely gotten rid of the influence of the name "Situ Lingran" on her.

Recalling the dream, Opal pinched his eyebrows a little helplessly and smiled bitterly.

But she still had a lot of things to sit on at the moment, and she didn't have time to worry about such things for the time being—for example, dealing with an old fox who had become a master, and a certain professor who was looking at her with a gaze that could definitely be described as "gloomy", and...... A half-giant who was looking at himself with a feverish gaze.

But before that, Opal had already rushed to his unicorn form, and after checking the situation and finding that it was just a simple loss of strength, he nodded to the Fei Leng Emerald who came out of the Forbidden Forest and signaled "It's okay", and then glanced at Philnet, who had already hidden his form, and immediately got up and walked into Hagrid's cabin.

A few seconds later, Opal walked out with the Norwegian backback baby in his arms and stood in front of the female dragon, who had been quiet in the presence of the patriarch.

[I can understand a mother's anxiety about her child.] ]

Carefully placing the frightened baby dragon to the ground a few meters away from the female dragon, Opal looked up at it, with a humble attitude and no arrogance, [Now I return your child to you, and apologize for the unpleasantness caused by this incident.] But equally, I hope you can leave this field as soon as possible with your children. ]

The female dragon's eyes fixed on Opal for a long time, then swept over Filnet on the side, and finally lowered her title and raised the young dragon: "I respect your decision to be blessed as 'that one', and the king who guards this land, and I will not hold others accountable for this matter. 】

After that, it left with the baby dragon.

"Your Highness Opal, the situation of the unicorn is dangerous."

Then, after receiving Opal's eye signal, Emerald immediately rushed to Dumbledore, who came over after confirming that the alarm was lifted, and said, "We need your help." ”

[I see.] ]

Opal turned his face and looked at Dumbledore with an inquiring gaze.

"Do what you want to do. No one wants to see unicorns hurt. ”

Stopping Snape and Hagrid, who seemed to want to speak, Dumbledore nodded at Opal as a nod of permission, "I'll grant you leave." But hopefully when the unicorn wakes up, you can come to me and tell me about it. ”

[Please feel assured.] ]

Opal nodded, then let Fei Leng Emerald carry him and put him on its back, and followed the centaur clan with "herself" in a coma back into the Forbidden Forest.

、

[Mr. Thestrals, excuse me.] ]

After returning to the Centaur station, Opal turned to look to the other side, [Because the situation is more complicated right now, I would like to contact Miss Vivien.] ]

Standing there was a horse-like creature that was hard to see once it was in the prototype.

It has a beautiful black body and a mane of the same color, but its head is like a dragon - but in the sockets of his eyes are white pupils with no pupils, and from the shoulder blades on his back, a pair of dragon-like black membranous wings extend, and the hooves are burning with blue flames.

Thestrals, creatures of dark attributes that can only be seen by those who have experienced the cycle of death. And in front of Opal at this moment is the king who stands at the top of the Thestrals' Nightmare.

The Thestrals' silver-white pupils swept over Opal, nodded silently, and then disappeared without a trace.

"Has Thestrals already left?"

Although they couldn't see it, they clearly felt that the sense of coercion that seemed to be absent was gone, and the centaurs, including Fei Lengcui, were obviously relieved.

[Yes.] ]

Nodding his head, Opal turned his gaze back to his comatose "self" - it was a strange feeling to see him, and he frowned and remembered something else, [Nagini. ]

{What?} Miss. }

A hissing voice swam over, and Nagini was now coiled on her side, [Nagini, you should be able to contact Riddle, right?] ]

{Miss Opal has something to look for her master?} }

Nagini did not answer Opal's words directly, but only confirmed the content first.

[I want Riddle's timer, if only you could help me convey this to Riddle.] ]

Opar had always felt familiar to Vivien of what she had seen at Vivien, and when she saw Nagini, she remembered that she had seen the same thing with Riddle as a child—but at the time she had no idea what it was for.

Anyway, the "future" has already told her the solution to the problem about the right to use the time returner......

As for how Riddle got the timer that belongs to the controlled product...... Opal felt that he was not interested in this kind of thing, and there was no need to figure it out. (Tianyin: My setting here is that this time return device belongs to Myrtle.,Anyone who has watched the second part of HP should know what's going on.。 Anyway, JK didn't say anything about Myrtle's college. ）

{Okay.} }

After watching Nagini disappear from his sight, Opal, who knew that things were almost completely on the known trajectory, exhaled and rubbed his temples.

Just as she was about to breathe a sigh of relief, the Thestrals, who had left earlier, reappeared in her field of vision—and this time not in the form of Thestrals, but in his human form.

Her long, inky black hair was simply tied up behind her ears and hung down at the back of her head, and two strands of silver-white sideburns were left on either side of her cheeks. Under the sword eyebrows that are obliquely raised into the sideburns, the eyes with beautiful eyes are closed, and the facial features are more delicate than handsome - but because of the temperament, they do not look feminine at all.

Dressed in a black outfit with a blue flame pattern on it, similar to a corset knight's suit, the "Thestrals" Filnet is more like a guardian knight from the Middle Ages than a king.

[Mr. Thestrals?] ]

Tilting his head, Opal looked at him curiously and waited for the following.

"The Secret Land of the Lake."

Philnet, who could make a voice because she had taken on a human form, stretched out her hand in the direction of Opal, and placed a disposable portkey made of amethyst in her open palm, "You and her." ”

[I see.] ]

Opal nodded and took the portkey from Filnet's hand, [Mr. Thestrals, come over and help, I can't move myself as a unicorn.] ]

Philnet means that she will go to the secret realm of the lake with her in human form and her unicorn.

If he hadn't been with him for a considerable amount of time, others would definitely think his words were clueless.

But for Opal, she was used to his way of saying it, though it did make a lot of jokes at first.
