When World's World Pirates roamed the seas, the Rocks Pirates were entrenched in the New World, and the God Valley Incident had not yet begun.
Oldest One, Bondi World simply wanted to go on an adventure at sea and dreamed of being free to see the world.
However, as he became wanted by the World Government and clashed with the Navy and even the CP Organization several times, World began to become increasingly violent.
World originally only wanted to explore freely, began to become addicted to power.
The officers of the World Pirates initially wanted to build a submarine to avoid conflict, but at World's insistence, they changed their minds and built a giant cannon to deter enemies from fighting them.
Indeed, the power of the More-More Fruit is terrifying; even without sophisticated development, it has demonstrated immense destructive power.
Ultimately, it was the CP Organization that turned a group of crew members against him, leaving World vulnerable on all sides, which finally led to his capture.
Moreover, after capturing him, he was neither executed nor imprisoned normally, but instead frozen in ice—in order to ensure that World could "survive" for a long time and prevent the More-More Fruit from reappearing!
This also made this "World Destroyer" Sig's primary target...
Freeze!
There are always unexpected things; it wouldn't be surprising if someone just froze and died, would it?
Sig felt that even if it were discovered, the World Government should look for the cause in the provider of the cryogenic technology.
Moreover, it hasn't been discovered yet—after Sig killed World in his sleep, he used the Rose Bishop's power to corrupt Wald's flesh and blood, making him appear as if he were a living dead, yet his body still showed signs of life.
If it were anyone else, the anomaly would have been noticed long ago.
But World is frozen in ice; as long as he still has a breath of life, no one will notice anything...
Although Sig is not currently a user of the More-More Fruit, he is already able to wield its power— the Shepherd's ability—and has already controlled More-More Fruit Devil!
Because there are no other beings with special abilities, the Momo Devil is currently in its most primitive form, almost unrecognizable as human. It appears to be composed of countless spheres forming its body, limbs, and even what looks like an exposed brain. Each sphere is constantly expanding and then shrinking, making it look extremely bizarre.
The Prison Demon and the Thunder-Thunder Demon appear more human-like because they incorporate parts of Sig's will.
The Shepherd's ability is to control Devil Fruits, so in terms of power scale, it is at its maximum from the start, equivalent to an Awakening state, but it can only control one Devil at a time.
At this moment, the "Momo Devil" appeared beside Sig in a semi-transparent form, invisible to ordinary people...
[We're almost at Marineford, aren't we? Aren't you their enemy? Can't resist causing some trouble?] Momo the Devil spoke in a seductive voice.
[No, it's still a long way off... The guy I most want to kill isn't here right now.] Sig communicated directly with the one who was bewitching him on a mental level.
The figure of Momo the Devil faded away, somewhat unwillingly...
The name "More-More Fruit" sounds a bit strange; it would be more accurate to call it "Genggeng Fruit."
It's almost the exact opposite of the power of the Float-Float Fruit.
The More-More Fruit can also change the properties of an object related to its "mass," such as gravity and inertia, but it doesn't reduce or even reverse them; instead, it can increase them by up to 100 times!
He can increase the volume, mass, and even speed of objects a hundredfold, causing terrifying destructive power, which is why World is known as the "World Destroyer".
Of course, no single ability is omnipotent; ultimately, it depends on one's own strength...
In the original work, World enlarged and accelerated the cannonballs of the super cannon by a hundred times, but he was still cleaved in two by Hawk Eyes.
If you look closely at Shiryu's words, you'll see that he uses his thumb to push against the guard, causing Raiu to extend slightly beyond the scabbard by about half a finger's length. Then, Raiu will quickly "slam" back into the scabbard at an extremely fast speed.
Although the acceleration distance was only half a finger's width, it was delivered with tremendous force with each pull...
Sig is also adapting to how to use the power of the More-More Fruit to enhance his combat abilities—directly using it to enhance projectiles and ranged weapons. Although simple and convenient, it's not enough against truly skilled opponents.
Like Hawk Eyes...
Even if Shiki threw an island down... or even if the Press-Press Fruit pulled down a small meteorite, he could still split it in two.
Simply increasing the power of projectiles may bring great strength, but it lacks soul.
Thanks to the Triangle Current, Shiryu traveled from Impel Down Marineford, the Marine Headquarters, in just a few hours.
"Shiryu" was nominally there to report on his duties, not to conduct an inspection, so Sengoku naturally wouldn't personally greet him.
However, a major was still waiting at the naval port. After the warship docked, he immediately led "Shiryu" to the Fleet Admiral's office.
"Hello, Vice Warden Shiryu, I've heard so much about you... I'm Daimyo Brannu. Fleet Admiral Sengoku sent me here to wait for you. Let's go see the Marshal now!" Brannu, with short green hair and a slightly receding hairline, welcomed Sig into the headquarters.
Throughout the entire process, Sig maintained Observation Haki, regardless of whether others noticed or considered it impolite.
If he realizes it's a trap and his identity has been exposed, Sig will react immediately.
Furthermore, Observation Haki is not as easily detected as the Byakugan's gaze; it is quite subtle, and very few people can detect it.
Thump thump thump--
Upon arriving at the door of the Fleet Admiral's Office on the top floor of Marine Headquarters, Major Brannu knocked. "Reporting to the Marshal, Vice Warden Shiryu has arrived."
"Yes, come in." Sengoku, standing behind his massive desk in a Commander Ikari posture, nodded to Brannu and said, "Major Brannu, you can go and work on the materials we discussed earlier."
"Yes!" Brannu readily agreed.
Brannu's fighting skills weren't particularly outstanding, but he was clearly in a crucial position for promotion, usually responsible for flipping through PowerPoint presentations and explaining the situation during meetings.
In the original story, seven years later, he had already risen to the Commodore...
At this moment, Shiryu unceremoniously pulled over the chair that had been prepared in front of Sengoku's table and plopped down on it.
At this moment, there was no third person in the Fleet Admiral's Office, only a pet sheep.
"I've already looked into the situation at Impel Down. Vice Warden Shiryu indeed fulfilled his promise, and even Warden Magellan praised you in his letter." Sengoku ignored Shiryu's minor rudeness.
"Haha, so I also made a token report, writing a few good words about him, so that others wouldn't think I'm petty." Shiryu said righteously, revealing his ulterior motives.
Sengoku:...
"I am satisfied with your actions in Impel Down. Now... are you ready to take on an even more important mission?" Sengoku knew Shiryu was a smart man, so he asked directly.
"No, I don't think this is more important than guarding Impel Down, but preparations are indeed underway. After all, Impel Down can be managed without me for now, so... does Fleet Admiral Sengoku have anyone he'd like to send to Impel Down?"
Shiryu a bit too direct, but Sengoku didn't deny it...
