Mysteries? Joy Boy? The Ancient Kingdom?

After Robin finished her reflections, she asked the question that had been bothering her.

Her intuition told her that Haku must know something!

So Robin spoke up, "Do you know Joy Boy?"

Haku's lips curled into a smile as she said, "It seems that the apology letter has given you quite a few questions."

"You knew all along!" Robin's eyes flashed with understanding. She knew Haku always knew things that others didn't.

Haku smiled and said, "Joy Boy was a man born 900 years ago in a highly civilized Kingdom, and also the first person to be called a 'Pirates'."

Robin's pupils contracted slightly, and she murmured, "The first person to be called Pirates!"

"That's right, exactly!" Haku said matter-of-factly.

He continued, "Joy Boy was a real human who existed during the 'Void Century,' and was once a companion of Zunesha. Furthermore, deep within the Sea Forest of Fish-Man Island, Joy Boy made a promise to Mermaid princess who was then the 'Poseidon' Poseidon. Unable to fulfill this promise to Fish-Man Island, he left behind the Poneglyph as an apology."

"So that's how that apology came about!" Robin exclaimed, drawing on his knowledge of history.

"Can you tell me why he failed to keep his promise to the Mermaid princess?" Robin asked again, revealing the question that had been on her mind.

Her intuition told her that Joy Boy might be directly connected to something the World Government was trying so hard to cover up!

Haku paused for a moment, seemingly weighing whether to tell Robin all the information. Looking into Robin's eager and determined eyes, he knew she wouldn't easily give up on exploring this mystery.

He began, "Robin! I don't know if I'm right or wrong, because this matter has been covered up for so many years! What can be reconstructed may not be accurate! Are you sure you want to hear it?"

Robin was slightly disappointed; even Haku wasn't sure about those things! But she still said, "Tell me about it, I want to hear it!"

Haku nodded. "The story of Joy Boy is closely linked to what we know as the 'Void Century.' In that deliberately erased period of history, Joy Boy played a crucial role. The reason he failed to fulfill his promise to the Mermaid princess was because..." Haku's voice lowered, "... he tried to save his own Kingdom, the Ancient Kingdom!"

Robin's breathing quickened; she felt as if she were standing before a door to an unknown world. She asked eagerly, "Ancient Kingdom? What are those?"

Haku took a deep breath and continued, "The Ancient Kingdom were a highly civilized nation, their technology far surpassing modern technology. However, it was precisely this immense power that alarmed the World Government. Fearing that the Ancient Kingdom's strength would threaten their dominance, the Ancient Kingdom World Government united with other forces and launched a war against them."

"The outcome of the war was brutal. Although the Ancient Kingdom possessed advanced technology, they ultimately perished under the combined attack of the World Government. However, at the moment of their demise, the King of the Ancient Kingdom inscribed an important message in the Poneglyph and spread it throughout the world."

"As you know, anyone who studies the Poneglyph, which are the secrets of that time, will inevitably face ruthless destruction from the World Government!"

Robin was stunned; she had never imagined she would hear such a shocking story. She suddenly realized that the truth she was seeking might be far more complex than she had imagined.

"Haku, do you know the location of all the Poneglyph? And do you know the real information contained in the Poneglyph?" Robin asked eagerly.

Haku shook her head. "Nobody knows. The Poneglyph are scattered all over the world. Only by finding all of Poneglyph can we piece together the complete information. Otherwise, I wouldn't be so unsure if the information I reconstructed is accurate! And the World Government has been secretly searching for these Poneglyph, trying to completely erase the existence of the Ancient Kingdom."

"I see!" Robin said softly.

Haku didn't offer any further explanation; what she had just said was enough for Robin to process for a while.

Just then, Haku heard Luffy shout, "Hey! Everyone, we can see the sea now!"

Haku smiled and said, "Welcome to the New World!"

The Thousand Sunny quickly crossed the sea, and Dark Clouds filled the sky, making it seem as if raindrops were about to fall.

Of course, this is New World, and those who truly venture here won't easily assume that what's in the sky are really raindrops.

Haku smiled and said, "Ready? Let's begin!"

Haku's words drew everyone's attention.

Suddenly, a huge hailstone fell from the side of the Thousand Sunny!

Zoro, Luffy, Sanji, and all the other combatants on the ship used their unique abilities to shatter the hailstones that were about to hit the Thousand Sunny!

"How could such huge hailstones fall here! What is this? Cotton?" Just when he thought he was about to kick a piece of hailstone, Chopper pointed to a ball of cotton!

Haku began, "Those are snowflakes, and there are more than just a few!"

As soon as he finished speaking, a thick layer of snow fell from the sky, blotting out the sun!

Seeing this, Robin used the power of the Flower-Flower Fruit to create two giant hands to block the heavy snow!

But that's not all!

Just when everyone thought it was over, a heavy rain began to fall! And the sea where the Thousand Sunny was located suddenly parted!

The Thousand Sunny was beginning to sink below the surface of the sea!

"What do we do! This sea is too strange. Are we really going to fall into the sea like this?!" Usopp said, clinging to the edge of the boat.

"Perhaps it will be smashed by Rock that are spat out before it even reaches the bottom of the sea!" Robin added quietly.

Soon, under Franky's control, the Thousand Sunny flew out of the separated the Sea!

As it was in the sky, lightning began to fall.

However, with both Katniss and Nami as users of the Rumble-Rumble Fruit, most of the lightning was absorbed by Nami before it even hit the ship.

Of course, most of the lightning in the sky was actually eaten by Zeus.

Once they reached normal waters, Haku smiled at the somewhat numb group and said, "How was it? Isn't the New World fun?"

"No! That wasn't fun!" Except for Luffy, who was full of energy and excitement, the others didn't want to go through what they had just experienced again!

However, this is just an appetizer in the New World!

The real problem is those marines who are eyeing the Pirates and waiting for them to come up from the sea!
