One Piece: I'll copy Luffy at Marineford and save Ace!

Su Mu knocked Vander Deiken away, preventing Noah from falling, which was tantamount to giving Fishman Island a new lease on life.

Meanwhile, the rest of the Straw Hat crew were fighting for Fishman Island and for the King's Army. They managed to defeat so many Fishman pirates in the plaza.

As humans, they saved Fishman Island and selflessly risked their lives for it amidst an army of 100,000. How could the people not love and be grateful to them?

The Ryugu and the Sunny drifted slowly across the sky.

As he passed through the streets, everyone who saw him cheered and shouted "Hero!"

Luffy, hearing someone below shout "Hero!", immediately became displeased. He grabbed at the coating on the side of the ship and shouted down:

"Don't call me a hero, give me the meat! Meat!"

"Oh, and there's wine too."

Zoro added from the side.

Not long after, the Sunny followed the Ryugu and arrived at Ryugu Castle.

The scene was pitch black, but after a short while, the palace lights suddenly came on, revealing a bright and beautiful stage.

Su Mu glanced at it and immediately understood that the people of Fishman Island had managed to create such a grand scene in just a few dozen minutes.

The entire palace was like a concert venue.

At the very center was an exquisitely decorated dining table, upon which various delicacies were prominently displayed.

The food was more varied and more delicious than what Luffy and his crew had eaten at the palace before.

It seems that, unlike last time when there was still some distance between them, Neptune put in a lot more effort at this banquet.

Every ordinary person also put in a lot of effort; otherwise, such a beautiful scene could not have been created in such a short test paper.

As the ship came to a stop, Luffy, Zoro, and the rest of the Straw Hat crew eagerly headed towards the central dining table!

Not far from the dining table was a stage, where many beautiful and eye-catching mermaids had appeared, singing and dancing to their hearts' content, their laughter echoing.

Sanji completely forgot about asking the chef on Fishman Island for that recipe, turned around and ran towards the stage, dancing with the beautiful mermaids.

The mermaids were overjoyed to see the hero on stage, and they even circled around Sanji.

Sanji's eyes were filled with hearts; he looked like he was about to ascend to heaven!

For a moment, the air was filled with singing and joy.

Su Mu was also starving. He grabbed a fish fillet in one hand and a cream dessert in the other, and devoured them in no time.

In contrast, Luffy's eating ability is as astonishing as ever. While others can eat a whole suckling pig in three bites, he can eat three suckling pigs in one bite.

The scene was filled with cheers from the beautiful mermaids and local residents, as well as busy delivery workers covered in sweat.

They stared blankly at the dishes that had vanished in the blink of an eye, marveling at how much this group of people could eat.

Su Mu took a sip of the wine brewed on Fishman Island; it had a strong grape flavor and a rich sweetness.

The sunshine here is continuous, which is equivalent to having no night, so the fruits grown here are exceptionally sweet due to the full effect of photosynthesis.

After finishing his wine, Su Mu started eating grapes and mangoes. Just as he was enjoying his meal, Nami suddenly came over.

"Let's go! The national treasury! Treasures! Su Mu, didn't you say you'd come with me to move the national treasury?"

Su Mu, who still had grapes in his mouth, paused for a moment upon hearing this, then nodded.

"Right, let's go. Do you know where the national treasury is?"

"do not know."

Upon hearing this, Su Mu looked up at Neptune at the table without any hesitation and asked:

"King Neptune, where is your treasury? Can we go and take a look... I mean, have a look?"

"Treasury?"

Neptune paused for a moment, then remembered his previous promise, and smiled, beckoning to the Right Minister who was not far away:

“Minister, our heroes wish to visit the national treasury. Take them there and give them whatever they desire.”

"Your Majesty...this..."

Upon hearing this, the Right Minister's expression turned troubled.

"Go ahead. You need to know that without them, Fishman Island will cease to exist. Treasure and such are meaningless."

"No, Your Majesty..."

"Go quickly, what are you hesitating for?!"

Neptune was somewhat displeased. Even he, a king, didn't seem troubled by the treasure, so why was a mere minister causing him trouble?!

"To tell you the truth, Your Majesty, our national treasury was inexplicably robbed during the recent battle in the square!"

"There's nothing left inside! We just got back and only just received the news; we haven't had a chance to tell you yet!"

"Oh, it got stolen..."

Neptune nodded thoughtfully, then his expression changed:

"What?! It's been stolen?!"

Upon hearing this, Nami's expression changed slightly, showing a hint of pain.

"W-what happened? The national treasury was robbed? The Fishman Island's national treasury can be robbed?"

Su Mu frowned and looked at Nami. Nami was clearly unhappy; the Straw Hat crew was supposed to get a share of the treasure...

"Take us there and let me see what's going on."

Su Mu looked at the Right Minister and said.

"Fine……"

Afterwards, the Right Minister led Su Mu and Nami out of the banquet hall and arrived at the gate of the national treasury.

When they saw the completely empty treasury, practically devoid of any resources, Su Mu and Nami were both slightly taken aback...

"How, how is it possible..."

Nami's eyes trembled slightly as she collapsed weakly to the ground, as if she had missed out on the treasures she could have obtained.

“Su, Sumu…”

Nami looked up at Su Mu with teary eyes, seemingly feeling a little sad.

Su Mu scratched his head and sighed helplessly.

He thought about it carefully, and if the theft of the national treasury wasn't committed by Vander Decken or Hody Jones's pirate crew, then there was only one other person.

That was the wet hair they brought on board, Caribou.

I had forgotten about him before, and I didn't know how he was after falling into the water, but now it seems that he is fine and still has the energy to steal treasure.

"Nami, I know who stole it. Don't worry, we'll get it back."

"Russing..."

As soon as Su Mu finished speaking, a commotion erupted from one of the rooms.

Immediately afterwards, a soft scream was heard and then vanished.

Nami and the Right Minister didn't hear it, but Su Mu heard it clearly.

But there was no worry on his face; instead, there was a hint of joy.

"As expected... you're still the same as ever, Caribou, trying to take Shirahoshi away, huh..."

Su Mu's lips curled into a smile as he looked at Nami:

"Nami, I know where the person who stole the treasure is. Come with me."

Upon hearing this, Nami's lifeless eyes suddenly lit up. She glanced at Su Mu and then looked at the Right Minister.

The Minister of the Right naturally understood Nami's meaning and shrugged indifferently:

"The king said you can take whatever you want, and if you find the treasure, it will all be yours."

"Su Mu! Let's go!!!"

Upon hearing the Right Minister's words, Nami instantly transformed into a streak of smoke, grabbing Su Mu and running away.

…………

The room where Shirahoshi is located.

"Beautiful mermaid princess! Hahahaha!"

Caribou suddenly appeared, transformed into a swamp.

The already tired Bai Xing's expression changed drastically. She screamed for less than a second before her mouth was stuffed with a lump of mud.

“Mermaid Princess… I just heard it! The King of Fishman Island, your father, said that you are the Ancient Weapon, the Sea King!!”

"The mermaid princess of Fishman Island, Poseidon the Sea King... either title would fetch a good price!! Hahahaha!"

Caribou burst into laughter:

"We've emptied Fishman Island's treasury again, and now we can even sell the Little Mermaid Princess. This trip was definitely worth it! Thanks a lot, Straw Hat crew, and thanks a lot, Bowl Cut!"

Caribou activated the Swamp-Swamp Fruit's power, merging half of Shirahoshi's body into it.
