Sig never found its "other half" around Dawn Island.
Six days later, Sig, Morio, and Yasopp set off together, preparing to travel from the Calm Belt to the New World.
As for why not everyone stayed behind to keep an eye on the Kingdom of Goa?
In Shanks' words, pirates are free; they can stay on land and work with kind and honest nobles to change the country. But they also have to do what pirates are supposed to do, such as hunting for treasure and sinking enemies...
Of course, through observing micro-expressions, Sig felt that Shanks probably had at least a small reason for this: he realized that he and Yasopp didn't get along with An'er in the same way Shanks did with An'er.
That's why Shanks decided to let Sig search for that Devil Fruit... Shanks could sense that Sig had designs on the Vampire Fruit.
As Shanks said when Sig joined the crew—this is not a place to cause Affliction to any of our comrades.
Although only three people were going to enter the Calm Belt, the Red Force still escorted them all the way to the edge of the Calm Belt before lowering their small boat—the same small boat that Sig usually used, with a "Bananaman joint."
It was already a bit cramped with three people sitting on it.
Sig is skilled in naval combat, and Yasopp doesn't have Devil Fruit, so the three of them entering the Calm Belt together isn't too dangerous.
"Bananaman is so convenient..." Morio remarked, looking at Bananaman transformed into a jet propulsion device and attached to the slot at the stern.
"Yes, but only if it's not cloudy." Sig nodded.
The boat is not moving very fast, just enough for Bananaman to use up all the energy she accumulated during the day.
Before long, all three of Sig keenly sensed that the wind had stopped.
The sea was as calm as a mirror, like a lake, but the danger hidden beneath the tranquility made the three members of the Red-Hair Pirates tense.
For Sig and his companions, ordinary Sea King were merely "extra food."
But...
Giant sea creatures that are tens of meters long are called Sea King, Calm Belt are also Sea King!
Being big is impressive. In a decade or so, Zunesha tens of thousands of meters long, could easily defeat Jack the Drought the Drought with a single swing of its trunk. Right now, in the Red-Hair Pirates, apart from Shanks himself, no one dares to say they can compare to Jack the Drought a decade or so from now.
Therefore, Sig and his companions remained tense and discreet even in the Calm Belt.
Now, a row of Seastone Bullets is embedded in the hull of Sig's ship—these are all Yasopp's stock, some captured during battles with the navy, and others brought by Gennosuke when he boarded the ship.
When Gennosuke, he used Seastone Bullets as travel expenses...
After learning about this from Morio, Sig became even more convinced that Gennosuke was a swordsman from Wano Country.
Placing Seastone at the bottom of a ship can prevent it from being spotted by Sea King, unless one is unlucky enough to be seen or touched by the naked eye.
However, the navy's warships that can navigate in Calm Belt probably don't just use Seastone in such a simple way; simply embedding some Seastone wouldn't provide the same level of concealment as naval warships.
Most of the day later, as night fell, Sig suddenly woke up and sat up.
Morio, who was on night watch, spoke to Sig upon seeing this, "Last time, when we went about this far in, Lucky Roo's oar unfortunately hit a Sea King was over 500 meters long on the head. Although it quickly stunned the creature, it still alerted the surrounding area, and more and more Sea King gathered. We could only rely on Lucky Roo burning its fat to 'blow' us back..."
The Red-Hair Pirates do have Record of successfully crossing the Calm Belt, it just takes a bit of luck.
As for now, at Bananaman's speed, he has probably only penetrated one-fifth of the depth of the Calm Belt. It will take at least two more days to completely cross it.
Seeing that Sig didn't seem inclined to lie back down or chat, Morio asked, "Hmm? Are you going to pee?"
Sig ignored him, continuing to look around with a serious expression.
Seeing this, Morio also became nervous. "What did you sense?"
Now, most of the Red-Hair Pirates members know that Sig can sense things that humans cannot.
"Who's speaking?" Sig asked, his face grim yet filled with anticipation.
"Huh? I'm talking, what's wrong?" Morio's mouth was always so talkative.
"I wasn't talking about you..." Sig stood up and called out in all directions, "Who's speaking? Are you Sea King? Can you hear me?"
Indeed, upon entering the Calm Belt, Sig heard a "sound" coming from the seabed.
Sig knew, of course, that in the original work, Roger and Kozuki Oden had heard the super Sea King speaking on their way to Fish-Man Island —they were exclaiming, "Our king is about to be born."
These colossal Sea King, unlike the other mindless Sea King, clearly possess a certain level of intelligence, and for some reason, they have been waiting for the birth of a "king"—which should refer to "Sea King" Shirahoshi.
When Sig entered the Calm Belt before, perhaps he didn't go deep enough to reach the location of these colossal Sea King, or perhaps they weren't speaking, or perhaps Sig, at Sequence 8, simply couldn't hear them...
[The king can speak now...]
[As expected of the king, so cute.]
[Unfortunately, they still can't hear our voices or communicate with us.]
[It's almost here, the appointed day is almost here...]
[This time, I'll definitely fulfill the promise I made!]
[Huh? It seems like someone else can hear us again.]
[Just like those two people not long ago, they weren't even kings...]
[For humans, this has been going on for a very long time, hasn't it?]
The colossal Sea King did not respond to Sig's call, while Morio and Yasopp, who had already woken up, were pulling at Sig, trying to stop him from yelling, lest they attract the Sea King's attention.
A small number of ordinary Sea King is not a problem, but if they attract a whole swarm, or those super-large ones, they can only flee.
Sig still shouted, "Is the person you're waiting for the Princess of the Dragon Palace? What exactly is this unfinished promise you speak of?" Sig spoke, he transformed into something resembling Fish-Man.
Because discovering that "unearthing unknown information," especially information that is important to the world and the times but has been buried, can greatly accelerate the progress of playing the role of "Knowledge Keeper," Sig would naturally be interested.
[He seems to... not only hear us talking, but also understand what we're saying?]
[It definitely shouldn't be "King"...]
[Wait, he looks like Fish-Man... Could he be the king?]
[Idiot! That's clearly a male Fish-Man. The king can only be Mermaid Princess, and didn't we all sense it when the king was born?]
"Huh? You two who arrived 'soon' ago, can't you understand what you're saying? Can you please pay attention to me? Actually, I also have a very kingly aura!"
Sig kept trying to strike up a conversation...
