Where is this place?
Yamato looked at the uneven ground beneath his feet with a sense of bewilderment. All the way to the boundless horizon in the distance, everything was so empty, and the sky was pitch black.
"A dream... let's see if this is better," Sig said matter-of-factly.
Just now, after Yamato's reminder, Sig thought of something and told Yamato to go to sleep first.
Yamato was confused, but out of trust, he quickly fell asleep...
Well, even with Yamato's Conqueror's Haki, Sig couldn't hypnotize her; she fell asleep so quickly on her own merits.
In terms of trust in his "comrades," Yamato is still very much like "Oden."
Sig then entered Yamato's dream and wove this scene together.
"What are you going to show me?" Yamato asked, looking at Sig Yamato a puzzled expression.
"We're on the moon right now... Of course, I've never been to the moon either; I just imagined this scene from the shadow I saw when I looked up at the night sky," Sig explained.
Because it's a dream, it doesn't make sense; even though there's no light, Yamato can still see Sig right in front of him.
But in the next moment, light appeared...
"There, is the Sun... Hmm, about this big and this hot, that's good." Sig simulated the Sun again in his dream.
Because it was a dream, even though it was the Sun, it wasn't dazzling to Yamato when he looked directly at it.
"Next, there is the Blue Star," Sig said, quoting the name given to the mother planet on the high seas.
This word is rarely heard in Wano Country.
The blue star appears blurry, but one can still see the Red Line Continent and the Grand Line that intersect to divide it into four parts.
Glaciers exist in the North Sea and the South Sea, and the Blue Star slowly rotates around these two ends as its axis.
The reason we can see the "Grand Line" is because the area representing this region is extremely blurry, making it impossible to discern anything...
"The chaotic magnetic field and disordered atmospheric refraction make the true face of the Grand Line unknown to anyone," Sig said helplessly.
These are the fundamental rules of this world, Sig's White Tower route... at least the Sequence 6 White Tower route, is beyond deciphering!
"However, we can make an assumption."
As Sig spoke, three islands appeared on the Grand Line between the North Blue and the West Blue: one rising abruptly from the ground, one with a towering tree reaching the sky, and one with a giant skull rock— Wano Country, Elbaf, Hachinosu!
If they were really on the moon, Yamato wouldn't be able to see such detail from this distance. However, in a dream, logic doesn't matter; as long as Sig wants her to see it, that's enough.
"And then?" Yamato still didn't understand.
"Something's still missing, this strange light, and... strange atmospheric refraction." Sig said, and the rules of "light" in the dream began to change.
Whether on land, sea, or in the sky, there is Seastone Factor, only the concentration varies. Perhaps this is why the atmospheric refraction here is so strange—on the Grand Line, the concentration of Seastone Factor in the atmosphere is higher and more disordered, which makes it particularly peculiar.
Sig began studying the refraction of light from the very beginning of "ozone production through electrical discharge," and the reasons... need no further explanation.
At this moment, Sig, on Earth and on the Moon, simulated atmospheric refraction and moved Earth so that, from the Moon's perspective, it would completely block the Sun... well, not completely, only the central part; a large ring could still be seen.
However, the effects are already evident!
On Earth before Sig's journey, when the Earth completely blocked the Moon, a red Moon could be seen instead—because while direct sunlight was blocked, refracted light was not completely blocked and was predominantly in the red spectrum.
In the world of One Piece...
After being refracted by the atmosphere of the Seastone in the Blue Star, the Blue Star, which blocks the center of the Sun, appears even more blue, and some shadows seem to overlap on its surface.
Because the side of the moon that is actually facing the sun is the side that is not illuminated, and should normally be completely dark, however, due to atmospheric refraction, from the moon's perspective, the side facing the Sun is refracted.
If you were on Earth, you would see a faintly blue, but very blurry, Moon.
Meanwhile, on the moon, the blue shadow in the center of the Sun, along with the indistinct islands, is the shadow of the side of the blue planet facing the Sun. The dark side is merely a "screen"—because the moon is obscured and does not receive direct moonlight, the screen effect becomes even clearer.
"So what we're seeing now is the side of the Blue Star facing the Sun? So what?" Yamato still didn't understand.
Sig then controlled the simulated rotation, positioning the three islands directly opposite the other side, and said, "Now the shadows of Wano Country, Giant Country, and Hachinosu are all reflected on this side... If Bilca could send a signal, for example... if there were a 'lamp' that could be seen even from the moon..."
Under Sig's control, a point of light illuminates between the three islands...
"What is that? Laugh Tale?" Yamato asked Yamato and excitedly.
Sig said helplessly, "I don't know either, I just feel... it would be nice to have a lamp."
It wasn't just Imagination; it reminded me of "The Lights of Skypiea."
For the Warrior of Skypiea, the "light of Skypiea" is actually the Golden Bell, and the so-called "lighting" actually means "ringing".
However, from a linguistic perspective, the phrase "ringing the Golden Bell" must be interpreted as "lighting the lamp of Skypiea" for a reason; perhaps... there really is a lamp? Or perhaps it's not a lamp, but something that emits light.
As for Skypiea, although it was on Jaya Island, Sig had actually guessed it beforehand. Returning it to the sky and back to Bilca was something the Moon person had planned... it's just that too many things happened that they hadn't foreseen.
At that moment, Sig imagined a light signal, which he found perfectly reasonable.
In other words...
When the Sun, blue star, and Moon are aligned, the moon can see the reflection of the "light-facing side" on the "shadowed side" of blue star. At this time, as long as Mishima is on the light-facing side, and Bilca on the shadowed side releases a light signal, the location of Laugh Tale can be pointed out!
"So... Laugh Tale is right there?" Yamato pointed at the point of light, his eyes shining brightly.
Sig could sense that she even had an urge to skip work and join Sig on his "final adventure," but a sense of responsibility suppressed that feeling.
This made Sig even more embarrassed...
"Ahem, I can't be sure about the locations of the islands on the Grand Line either. The three islands and the light... are all just my imagination." Sig wasn't embarrassed at all. Being able to simulate it to this extent was already worthy of the Sequence 6 White Tower route!
However, Yamato's expectant look made Sig a little embarrassed.
Sig finally understood why Roger and Oden had gone to Ohara!
