Battle of Observation, Historical Mist

"Lady Brulee, all the materials have been delivered."

Because Cocoa Island, where Brulee lives, is located on the edge of Whole Cake Island, all sorts of 'dream ingredients' plundered from the New World were transported from here to Whole Cake Chateau, so there were actually some left over. — This is also why Brulee suggested making a new 'wedding cake'.

"Brulee Pudding, today should have been your joyous day, but it was ruined by Germa 66, the Straw Hat crew, and the Fire Tank Pirates. We are all indignant on your behalf..."

"It's alright. Compared to myself, the people of the Whole Cake Island are more important. Our top priority now is to make a 'wedding cake' to cure Mom's Hunger Pangs. Don't worry, I won't let the Whole Cake Island be destroyed."

Faced with the energetic young girl, a group of people from Chocolate Town were moved to tears.

"Lady Brulee is so strong!!"

The other chefs involved in making the 'wedding cake' were also transferred to this Chocolate Town via the 'mirror tunnel' to await orders, so:

"Hurry up, everyone! Every second counts!"

Upon seeing Brulee dressed as a chef, Sanji's eyes lit up with hearts as he reverted to his old ways.

"Wow—Little Brulee's chef's outfit is so cute~~!"

Snap,

Brulee cannot rise again.

?!

Is it really necessary to 'monitor' these two guys?

Charlotte Custard rubbed her temples, feeling that sending her to warn them about the 'poisoning' was completely unnecessary. She'd be more worried about whether those two could even make a decent cake...

As it turned out, her worries were completely unnecessary.

"Quickly, everyone get moving! You're in charge of baking the cake; Brulee, watch over the tempering of the chocolate..."

Once in cooking mode, Sanji becomes full of confidence and control. All the chefs in his hands become like interlocking gears, methodically and rapidly turning various raw materials into ingredients, leaving Charlotte Custard dumbfounded.

She's a cake-making expert, after all, but compared to Sanji...

It's not worth mentioning.

"The younger generation is truly formidable!"

Even 'Streusen' has to admit that some people are truly born to be 'kings' in a certain field!

"Rubber King Ape Crow Cannon!"

Facing a dense barrage of fists, Charlotte Katakuri stood rooted to the spot, letting the rain of blows pierce through his body! Even though the fists were coated with Haki capable of splitting mountains and shattering seas, they couldn't harm him in the slightest. Even if:

"Rubber Lion King Seal!"

Boom—

After his fist attack failed, Luffy unleashed a powerful palm strike, causing an indescribable shockwave and roar that instantly reverberated throughout the entire battlefield. It was as if the ground beneath Katakuri's feet had been bitten off by an invisible Sea King, and a massive trench hundreds of meters long was carved across the land! Debris flew everywhere like cannonballs, and the entire battlefield trembled violently.

"Armament Haki? Useless."

Although Luffy's attacks were incredibly powerful, neither his tangible fists nor his intangible Haki could harm Katakuri. And his attacks:

"Rubber Ape—"

"Kakumochi!"

A fist covered in Armament Haki slammed into Luffy's raised arm, not only halting Luffy's attack but also causing Luffy's arm, which was also covered in Armament Haki, to feel a piercing pain.

"Rubber Rhinoceros—"

"Yan Mo!"

Katakuri's kick landed on Luffy's lower body first, causing Luffy, in his 'Fourth Gear' state, to stumble and fall to the side.

Oops!

Ignoring his disheveled Luffy quickly rolled to the side to dodge, and at the same time, as he stood up, he threw a punch in the direction that his Observation Haki had sensed.

"Rubber Cluster"

"Nuri Ashi!"

However, just like before, before Luffy could even throw a punch, a dense barrage of mochi- Armament Haki slammed into him, shattering his attack. Those were Katakuri's arms formed from mochi, much like the 'Gum-Gum Crow Cannon' Luffy was about to use, only:

"Aaaaaaah!!!"

After a sudden, frustrated roar as he stood up, Luffy was forced to face reality:

"Feeling anxious, aren't you? You try to throw a punch and I attack your arm; you try to kick and I attack your lower body; you don't even get a chance to 'strike' before I've already subdued you..."

"This is the result of having your moves read; you are no match for me."

Katakuri wasn't being sarcastic; he was simply stating the facts.

"But this isn't your fault. You're still young, so just obediently submit to 'Mom's' command—"

"No way!"

Luffy took a deep breath and assumed a fighting stance once more.

"If I submit to 'Big Mom's' command, how can I ever become the King of the Pirates? Besides:"

"I absolutely hate that guy who destroys other people all the time!!"

········

"Don't you like it? What a capricious reason."

Faced with Luffy, Katakuri said nothing more, for to do so would be to insult Luffy and himself.

Bang!

"Gomu Gomu Thor Elephant Gun!"

"Gigant Mochi!"

The two enormous, swollen fists collided, and the battle resumed once more.

!?

"Hehe~~ Are you getting anxious now that your captain is at a disadvantage?"

Roman didn't respond to Perospero's smug words at all. He wasn't even paying attention to Luffy —after all, he believed Luffy was the type to grow stronger against stronger opponents, but the information in his hands was...

This is the 'Poneglyph' that Brook copied from Big Mom. One of the maps is the coordinates of the sea chart. Roman doesn't even want to look at this! Although he can understand it, if Roman dares to do it himself, he will definitely make a huge mistake. It's better to leave it to Nami.

The other two are very... eerie. Holding these two 'Poneglyph' translated by Robin, even with a mask on, Roman's fluctuating aura speaks volumes about the turmoil within him.

'Roman, have you seen Robin's translation?'

Nami's voice reached his ears, and Roman only needed to 'think' for a moment to convey what he wanted to say.

'Hmm, this thing...'

'Right? It's like it was tailor-made for us.'

The first Poneglyph features a weapon that Roman and Nami are very familiar with!

Railgun.

This is a weapon that combines the advantages of coilguns (which can fire large-mass projectiles) and railguns (which can fire hypersonic projectiles). It is a... space-based weapon! Simply put, it is the Railgun 3.0. That's right, it is an advanced version of the 'Railgun' carried by the Sunny Merry.

Of course, the 'Railgun' on this piece of paper is also powered by Devil Fruit abilities, which is very characteristic of this world.

If the first 'Poneglyph' was somewhat normal, then the second 'Poneglyph' was the reason for Roman's agitation! The second 'Poneglyph' wasn't a weapon, but a declaration:

My friends, today I want to tell you that although we will face all kinds of difficulties and setbacks in the present and the future, I still have a dream.

I dream that one day we will end this barbaric, war-torn, and bloody world, and spread the light of civilization across the oceans, truly fulfilling the promise we made together: that peace and joy will fill the world, and that all men, regardless of race, will be created equal!

I dream that one day, on the Red Line, giants and Fish-Man will be able to sit together and share their brotherhood.

I have a dream that one day in Mary Geoise, all the kings of the nations will come together to settle their disputes through peace talks rather than war.

I dream that one day all people will be judged, not by the degree of their birth but by the degree of their character, in their country, just as we are.

I dream that one day, the Longarm Tribe and Longleg Tribe will end their hundred-year war, the Giant race and Tontatta will be able to walk openly in any country, and the Fish-Man and we will no longer be legends and myths.

I dream that one day the islands will rise, the red serpent will break apart, the whole world will be united, cheers will resound across the Four Seas, and smiles will grace the faces of all intelligent beings.

I believe that day will come eventually. My comrades, with you by my side, I will forge ahead without hesitation!

—Joy Boy

········

"It's really... it's really..."

Roman stared at the 'Golden Dream' on the paper, looking it over and over. Although he couldn't discern anything 'absurd' between the lines, it was just too—

"Something that is utterly speechless."

That's impossible!

Could it be that Dr. Jin also time-traveled? However:

"As expected, Joy Boy..."

As mentioned above, 'Fish-Man and we are no longer legends and myths,' but eight hundred years ago, the only ones who would be called 'myths' were the Skypieans, or Moon Person, who descended from the sky with wings on their backs and possessed technology that was like a 'miracle.'

The Poneglyph in his hand is most likely the one Jinbe found in the underwater ruins. —And Roman remembers those underwater ruins as a corner of what was once a 'Great Kingdom'.

Therefore, the so-called 'Void Century' and the vanished 'Great Kingdom' were most likely nations established by the Moon Person. Otherwise:

A nation suddenly appears within a hundred years, then becomes so powerful that only a twenty-nation coalition, the precursor to World Government, can contend with it. Then, all that's needed is to erase a hundred years of history, and the answer becomes obvious:

The Great Kingdom is made up of Moon Person fell from the sky!

Only·····

Golden Dream—?

'Roman, Roman, Roman!!'

?!

Sorry, I was just thinking about something.

'Honestly, you can't wait to get anything that can enhance your combat power...'

Unfortunately, even Nami, who understands Roman well, misjudged the situation this time. Roman wasn't due to that 'Railgun' but rather...

"Never mind, "Nami's voice brought Roman back to his senses. He shook his head. "This is just an ancient relic from eight hundred years ago. Whatever its secrets, it's all gone now. What's important now is..."

Luffy was being forced to Luffy by Katakuri.

P. S.: Ahem, Oda is too long-winded, hiding things away, so I'll fill in the background myself. Of course, it's all based on being as 'reasonable' as possible.
