After the "Four Emperors' Pact," Red-Hair and his crew went to the North Blue to search for treasure, causing Big News Morgans. This also revealed Sig's absence, leading Rayleigh to speculate that Sig might have returned to Fish-Man Island. However, he never saw him and instead went to find Shyarly...
Shyarly couldn't predict when Sig would return to Fish-Man Island, but Rayleigh asked her to predict something else related to Sig, which Shyarly refused. Also, because of Arlong, Rayleigh believed that if Sig came to Fish-Man Island, Shyarly might have news of him.
But unexpectedly, Sig!
Even in front of Rayleigh, who knew the truth, Sig didn't budge on the matter of "Sea King," so Rayleigh didn't bring it up again.
"You're not someone who wants to become the 'One Piece,' are you? Why are you looking for One Piece? Is it just for your Captain?" Rayleigh asked curiously.
"Why? If the reason is this Kabu, which is about as much milk as it's filled with, it's probably for our boss..."
Sig also wondered why Shyarly's Kabu was so bitter...
"Half?" Rayleigh confirmed.
Shyarly exhaled a puff of smoke, then explained, "Sorry, there's no milk today."
Sig:...
Hmm, it's a bit of a mismatch between what was advertised and what was actually delivered. The coffee shop always seemed to have a lot of milk in it when you first entered.
"Actually, what I was trying to say was that there is a little bit," Sig explained.
I had thought there would at least be some milk!
Rayleigh:...
"What about the coffee?" Rayleigh pressed for the main reason.
Sig grinned and said, "Isn't it obvious? Although we don't know exactly what it is, it's definitely something that will make the World Government uncomfortable."
Seeing that Sig made no attempt to hide his "harmful but self-defeating" nature, Rayleigh couldn't help but rub his messy head.
"Perhaps it's different from what you think, otherwise... Roger probably wouldn't have left those words behind," Rayleigh said vaguely.
Sig could tell that Rayleigh meant that One Piece was at least not some kind of super weapon.
"When you were in the East China Sea, you met an interesting little boy, right? I heard he had a similar dream to my Captain..." Rayleigh suddenly changed the subject.
Although Rayleigh acted as if he had just happened to think of Luffy, Sig could tell that his real purpose was still with him, and mentioning Luffy was just a pretext.
Rayleigh's Observation Haki meant he was able to detect Sig's spying, so Sig didn't use Observation Haki to directly read his emotions, but rather "read his face".
"Come to think of it, he's not a child anymore," Sig added.
Sig estimates that it will be about two or three years before Luffy — Sig doesn't know exactly whether it's 1519 or 1520, since the story doesn't start with Luffy sail. However, in the original work, the Paramount War definitely happened in 1520, at which point Luffy had been in the Grand Line for less than six months...
This is a speedrunning pirate!
Judging from Sig's expression and tone, Rayleigh understood that Sig knew what that "dream" referred to.
That is to say...
A global party.
"What do you think? Hahaha, isn't that childish?" Rayleigh seemed to be joking, but he was actually quite concerned about Sig's attitude.
"It wasn't exactly childish. Actually... I did teach Luffy a way to achieve his dream back then!" Sig said seriously.
"Oh? You have a way to make that much money? No wonder you're called the Sea King." Rayleigh was clearly not serious; this wasn't something he cared about.
"No, I mean, with so much money, how do you invite the whole world to a banquet... After all, there are still some difficult guys, right?" Sig moved closer to Rayleigh.
Upon hearing this, Rayleigh's eyes lit up, as if he were eagerly anticipating the answer...
"Just take care of all the troublesome ones, after all, there's no need for a feast for the dead... Hahaha." Sig said with a tasteless laugh.
Shyarly looked at the two of them with disdain, thinking to herself: Why would someone drink coffee and then suddenly start banging on the bar? Why don't you go to a pub?
However, Rayleigh did not laugh; instead, his expression became somewhat serious.
"If you really want to see One Piece... remember, think twice before you act," Rayleigh finally reminded Sig earnestly.
Because his expression was too serious at that moment, Sig couldn't read anything, and because his powerful Conqueror's Haki was already subtly overflowing, Sig naturally couldn't read his thoughts using the power of the mystical realm.
Sig didn't necessarily intend to use Rayleigh as a breakthrough point to obtain clues about One Piece.
It wasn't for reasons like "pirate spirit" or "treasure hunting passion," but rather... Firstly, Rayleigh's Conqueror's Haki was too strong, so even if Sig had planned and prepared meticulously, the chances of successfully hypnotizing him were slim; secondly, Sig was already prepared to use the "prophecy" of Laugh Tale's direction as his own Promotion Ceremony.
In short, the information pointing to Laugh Tale is undoubtedly "important enough," and Sig already understands the principle behind Laugh Tale —the "Sun's Harmony" uses the four islands on the front and back sides of the Blue Star for comprehensive positioning.
Furthermore, this scene is cyclical. If Sig can simulate this scene in his mind, then it is undoubtedly a kind of prophecy—the content of the prophecy is "the positional relationship of the four islands when the Sun's Harmony occur in the future!"
For some reason, Rayleigh's reminder gave Sig a bad feeling.
However, Sig didn't think too much about it—with his current "Visionary + White Tower" mindset, if he didn't think of it immediately, he wouldn't be able to come up with anything further without gathering more information.
The authority over "prophecy" seems to be opening a breach precisely in this area!
After Rayleigh left, Sig continued to linger at the Mermaid Cafe...
After failing to get close to Shyarly by using "Arlong" as an excuse, Sig simply told the truth: he just wanted to explore Shyarly's prophetic abilities.
Unfortunately, Shyarly herself didn't understand where this ability came from.
However, Sig could sense that he was getting closer and closer to gaining the ability to "prophesy"...
Back on Whole Cake Island, Sig had already acquired a considerable amount of "prophetic" authority from the three Troll sisters—authorities that truly originated from Sig himself!
Although their prophetic abilities are nowhere near the level of a "prophet," they do indeed possess a portion of the "White Tower Path's" authority in prophecy...
Having already glimpsed Sig of hope, Sieg anonymously "worked" at the Mermaid Cafe —completely mimicking Shyarly's daily routine in order to get closer to obtaining information about her prophetic abilities.
