[Conan Doujin] The Mystery of Theseus

Puzzle20 Sky is the best.

As if it was a predetermined matter embedded in the script, the night before the school trip must not be able to sleep well.But this is not the eve of the school trip, the troubled "poor sleep", nor the high spirits brought about by the anticipation of the trip.Lights that go off prematurely, alarm clocks that are programmed to wake up early, it's all at odds with what a high school student's body is used to.

The time has not reached zero, and this is clearly the best time for carnival, but at this moment they have to lie on their backs on the bed with their eyes wide open, staring at the nothingness with nerve signals floating in their field of vision.Rationality whipped the brain, and repeatedly warned that "if you don't sleep at this time, the alarm clocks with frequent intervals will not be able to save you", but the spirit has been kept awake like that. The desire to "want to eat train bento as soon as possible" clearly manifested in my mind, the taste buds simulated its taste, and even the aroma was clearly identifiable in the air.

...Why are you so hungry at such a time?

Being so hungry that you can't sleep just because you "want to eat a train bento" seems to be a kind of mental excitement caused by looking forward to traveling too much.

It seems that the target of the curse of the school trip is not limited to elementary school students.

The next day, the sky was so blue that you could touch it, and it was an extremely fine weather for traveling.Although the two who set the alarm clock in advance were hypnotized by the "sleep for another 5 minutes" cycle spell, they were very lucky to sit out of breath one second before the train started. seat.

Because they were in such a hurry, the two who almost missed the car had no time to worry about whether they had the right seats.After the train started, the unsteady breath due to running calmed down a little, and Kuroba remembered to check the tickets of the two of them.

"Fortunately, I caught up, otherwise it would have been a big loss..." Kuroba's fingers were still trembling when he took out the ticket from the outer pocket of his backpack.He looked at Edogawa who was sitting on the side of the aisle beside him, fanning the wind with a piece of advertising paper he received at some time, "It seems that your seat is by the window, do you want to change it?"

"Don't be so troublesome," Edogawa didn't stop fanning the wind, but just cast a look to show that he didn't care, "It's not a kid who has never traveled far, it doesn't matter whether he sits by the window or not."

After what he said, Hei Yu felt a little unhappy. "Speaking like I'm the brat who really wants the window seat..."

I don't know when, "seat by the window" has become an unwritten synonym for "prepared for children".Probably it is precisely because this window leads to the outside world, which is obviously immutable but full of infinite possibilities in the eyes of children who are pure as white paper, that the window has become their special seat.For some adults who prefer to stay in their own narrow world, the aisle seat that they can leave freely without asking the people around them is the personal space they pursue.

but……

I had only experienced a series of life-threatening runs in the train station a few minutes ago, and after I settled down now, my legs were indeed too tired to move.Feeling the loss of strength at the knee joints, Kuroba no longer bothered about the troublesome thing of "changing seats" that requires standing up, but raised his cheeks and looked out the window at the telephone poles that flashed more and more frequently as the train accelerated.

In the morning when the sun had not fully woken up, the air still had the chill of the night to some extent, but at this moment in the carriage, the flow of cold wind could no longer be felt, replaced by the warmth surrounding the whole body.The sunlight was filtered through the car window, and the coolness in the morning made the nerves that had been tense since waking up uncontrollably relaxed and drowsy.

But the sun was so dazzling that even if you close your eyelids, there is a brightness that makes you sleepless.

Narrowing his eyes uncomfortably, Kuroba stretched out his hand to block the sunlight that came in.to no avail.The sound of the wheels hitting the track loops rhythmically in the ear, forming an uninterrupted but not monotonous background sound.Just squinting at the flashing buildings outside the window and the almost unchanged sky and distance, Kuroba couldn't even remember why he was sitting here at the moment.

If it were me in normal times, I should still be lying on my bed at home at this time, enjoying the privilege of sleeping in on weekends.

But now he is sitting here, looking at the scenery that doesn't matter whether he looks at it or not...

Why is this so.

If... I am not here at this moment...

Not long after, the train entered the tunnel.The clean windows reflected the lights and everything else in the car like a mirror.You can see Edogawa sitting next to you without turning your head.The child-like detective seemed to have fallen asleep for a while after getting in the car, and was flipping through the news on the phone screen at the moment.He curled his lips indifferently, Kuroba didn't intend to disturb him, and at the same time blinked his dry eyes from staring out the window for a long time.Unfortunately, it didn't take long for the train to get used to the darkened vision, and the train left the tunnel.

The sky that has escaped from the shelter of the building hits the eyes so unexpectedly that people lose even words in an instant.

so blue...

The momentary exclamation drove away the only trace of drowsiness left in the consciousness, but left the confusion entrenched in the trance.

Just staring blankly at the exaggeratedly blue sky with his chin in his hands, Kuroba subconsciously expressed his inner thoughts.

"Why is it blue..."

But these barely audible murmurs can easily be caught by the neighbors in the quiet carriage.Stopping the fingers that swipe the screen, Edogawa looked at him.

"Did you say anything?"

"Huh?" Hei Yu, who regained his composure in an instant, turned his head as if waking up from a dream, "What did I say?"

Edogawa said he did not hear too clearly. "I seem to hear 'blue'...?"

"Blue, blue... Ah!" Repeatedly focusing on the key word, Kuroba finally remembered those messy thoughts that flashed in his mind for a moment and were about to be forgotten. "I was just wondering...why is the sky blue."

"Why is it blue?" Frowning slightly, Edogawa's tone was a little laughing, "Even elementary school students don't ask such questions these days. Has your common sense been eaten away by something?" He pushed the glasses that were about to slide off the bridge of his nose with one hand, "The sky will appear blue because the particles in the atmosphere will scatter the light—"

"No, no, that's not what I'm thinking about," Hei Yu hurriedly waved his hands, indicating that he still possesses that knowledge as a high school student, "What I want to say is, why must it be 'blue'?"

Why not red, purple... or something else?

To Edogawa, this question is not fundamentally different from the previous one.He sorted out the knowledge he had mastered a little bit, and then started a new round of scientific explanation.

"That's because among the scattered light, the blue light has a shorter wavelength, and it is not easily absorbed during the transmission through the medium—"

"I know this!" With a high-five motion to signal Edogawa to stop his scientific lecture, Kuroba's brows and eyes showed helplessness, "I don't mean 'why is it blue' at the scientific level," trying to put Wu He sighed slightly after trying to sort out the logic, "I said, in the color spectrum of light, the normal order is always 'red orange yellow green blue blue purple'... right?"

"Everyone knows this level of knowledge." The interrupted Edogawa seemed to be upset about losing an opportunity to show off.

"I mean...why does it have to be in this order?" Despite the specific case, he felt like he was getting further and further away.Slightly swinging his fist in a frantic manner, Kuroba has already begun to regret that he specifically asked this question, "If 'blue' was not defined as 'blue' in the first place, would we still see blue? If there were other possibilities, could we see the sky in other colors?"

"Let me tell you, what's the difference between your question and 'Why is there a 1 after 2'?" There was something wrong with the black and white picture being reversed. Facing Kuroba who seemed to have entered a pattern of [-] whys, Edogawa couldn't help feeling a headache. "We can see that the sky is blue, but it doesn't mean it is really blue, but because the light of that wavelength is perceived as blue by the naked eye—"

As he tried to continue following the path of science to the end, he gradually stopped speaking as he spoke.

"After you said that," his voice also fell into the confusion of muttering to himself, "yes, why is it blue..."

But this confusion only stayed in his mind for a moment.What followed was an overwhelming sense of déjà vu that was almost suffocating.

blue sky……

There seemed to be a similar conversation between them, but at the wrong time, at the wrong place, and at the wrong point of entry.Everything is in the wrong context.

Stupid, the two are completely different.The blue of the sky is...

please...

You really don't have a dream.

If you simply indulge in your dreams, then...

"I said," recovering from the brief suffocation, Edogawa pushed his neighbor with his elbow who was still staring at the blue sky outside the window, "Have we... discussed this issue before?"

Kuroba, who turned his gaze back, blinked suspiciously, "No...no."

But the déjà vu just now is...

"Have you ever..." After pondering for a moment, Edogawa decided not to think too much about these things.In general, if they hadn't decided to go to Osaka and had changed the time and place, even if they had changed each other's identities and all the premise, they would have talked about this topic naturally.

All this is not accidental, but "must".Just like "the sky is blue", even if some things don't happen now, they will happen at another time and in another form as scheduled.It's like a script whose order has been shuffled, no matter how messed up the cause and effect are, its content will not change.

nothing will change...

Feeling vaguely that he had been thinking too much under the guidance of Kuroba, Edogawa shook his head, planning to do something to calm his mind.He looked at the watch on his wrist.

"Although it's still relatively early, we haven't had much breakfast yet," he called out Kuroba's attention, "Don't you really want to eat, train bento."

That's right, if you divert your attention, you won't be distracted by those inexplicable thoughts and déjà vu.

The scent of the train bento and the unchanging destination of the trip are the reality they are in now.

The author has something to say:

Gong Jun has something to say:

The philosophy of the color of the sky may be the same as the taste of ice cream, seemingly insignificant but important.

Or maybe it seems like something important, but it doesn't matter at all (laughs)

Have you all been stunned?

It doesn't matter if you get dizzy, come to a box of train bento to calm down (ah ha ha
