Crossover Anime: From DanMachi to Becoming a Garbage Scavenging Master

Fishman Island, Dragon Palace Reception Hall.

"You said—you're going to liberate the slaves?!"

King Neptune's voice deepened, and he confirmed the matter with a hint of seriousness.

"I've had enough." Explorer Tiger didn't avoid that gaze, but his voice trembled slightly from suppressing his emotions for so long. "The lives those people lived... it was hell on earth!!"

Even now, they are still being treated inhumanely—

"I've made up my mind!!"

Veins bulged on his forehead, and it sounded like thunder was roaring in his chest.

"Tiger," Neptune's voice lowered, "what exactly did you see along the way?"

"What I saw," Tiger said, raising his head in a low voice, "was the madness of humanity and the unfathomable malice of the World Government!"

A moment of silence fell over the hall.

Princess Otohime stood to one side without saying a word. Possessing a special kind of Observation Haki, she could hear the innermost thoughts of others.

She could hear the anger in Tiger's heart, a lament that pierced through his calm exterior and fell straight into her chest. Tears streamed down her cheeks, but she didn't wipe them away, nor could she utter a single word to stop him.

Just then, the void in the center of the hall suddenly distorted.

A deep blue whale silently emerged from the void, its body formed from condensed water. Its enormous fins gently brushed the air, creating a moist sea breeze. The whale opened its mouth, and five figures stepped out, landing steadily on the ground.

"Who is it!"

Tiger reacted instantly, flashing in front of Neptune, his fists clenched, his muscles tense like a fully drawn bowstring.

The man at the head of the group seemed completely unconcerned about the tense atmosphere. He glanced at the people present, then suddenly clapped his hands, a meaningful smile playing on his lips: "Sea Calendar 1506, it seems the time and place are just right!"

He took two steps forward and said in an almost chanting tone, "A new Poseidon has been born, and the world is about to undergo a great change."

Neptune's pupils constricted slightly.

Poseidon… that’s the name of an ancient weapon, and a secret passed down through generations of royalty. How could this person know about it?

"As children of the Sea God, are you ready—to welcome the arrival of the Third World?"

After speaking, the man raised his hand, and a ball of clear, deep blue water slowly condensed in his palm, emitting a strange fluctuation—

That wasn't the aura of a Devil Fruit, but some kind of ancient, purer power.

The shimmering water spread outwards like ripples, sweeping over the three people in front of them and continuing to extend outwards.

Neptune sensed neither hostility nor oppression from the shimmering water. The water reminded him of the sound of the tide he heard when he first secretly went to Chambord as a child, making him instinctively want to get closer.

Otohime's Observation Haki allowed her to hear the whispers of the entire ocean through the shimmering water.

Tiger also felt that magical power. It didn't have the alien feeling of a Devil Fruit user; instead, it soothed the mind and body, bringing a sense of peace.

The person in front of me seems to have the seawater as an integral part of his body.

Not long after, a commotion suddenly arose outside the Dragon Palace. A huge shadow was cast upon the coral dome, so large that it covered the entire sky.

The guards' exclamations came from afar, followed by the sound of hurried footsteps.

"Reporting to Your Majesty!"

Jinbe walked into the hall, followed by the blue fishman Arlong.

This man, who would later be known as "Sea Knight," was usually calm and collected, but at this moment, he couldn't hide the astonishment on his face.

"Your Majesty, five colossal sea kings have appeared around the Dragon Palace! They are merely guarding the perimeter, not approaching, and—"

He paused, as if to confirm that he hadn't misread it.

"And each of them had a large amount of sea king meat in its mouth, just sitting there on the reef... as if they were waiting for something."

Aaron stared at Tiger, laughing excitedly, "Hahaha, Boss Tiger! Those guys are all behaving themselves, not even daring to wag their tails! This is truly the first time I've ever seen anything like it!"

Neptune turned abruptly and looked at the man.

He didn't speak immediately; as the king of Dragon Palace, he knew better than anyone else—

The fact that the Sea Kings could gather here without showing any hostility indicates that it's not a matter of strength, but rather a higher level of ability.

If the other party harbored malicious intent, Dragon Palace City would probably no longer exist by now. Realizing the crux of the matter, he quickly calmed down.

"What... what is this?"

Zheng Tianxing opened his hand, and the ball of water slowly rotated in his palm, the ripples gradually subsiding.

"My name is Prometheus, and this shall be a celebratory gift—a joyous feast to celebrate the birth of the mermaid princess, Shirahoshi!"

Neptune took a deep breath, as if making a decision, and then ordered, "In that case, issue the order! A grand banquet will be held in the Dragon Palace today, and the entire nation will celebrate Princess Shirahoshi's 100th birthday!"

"yes!"

He paused, then turned to Tianxing and said, "As for the colossal sea kings outside the city, I request that Lord Prometheus accompany me to settle them."

Otohime stood to the side, her gaze unconsciously falling on the spot where the shimmering water had vanished, savoring the moment. She heard it; within that shimmering water, there seemed to be a faint voice—

She said, "Let him go, he will bring eternal joy to his people."

-----------------

Neptune watched as the man who called himself Prometheus stood in front of the several colossal sea kings and whispered something to them, as if he were communicating with them.

Then, as if they had reached some kind of consensus, the sea monsters quickly turned around and swam back to the deep sea.

The prey on the rocks on the shore was left aside, and Neptune ordered his soldiers to drag the sea king meat into the Dragon Palace in batches and hand it over to the chefs who were preparing the banquet.

Then, the couple, carrying Shirahoshi, led the group to the Sea Forest at the request of the person in front of them, and stopped in front of the stone tablet with the Poneglyph.

"Lord Prometheus, this is the Poneglyph of the Dragon Palace."

Tianxing examined the stone tablet before him, his gaze sweeping over the ancient characters. Sure enough, he couldn't understand a single word.

But it doesn't matter—he didn't come to the pirate world for the One Piece.

"Is this Nika's apology?"

Neptune didn't answer immediately, but his mind was already racing.

Poseidon, an ancient weapon, a royal secret...

The person in front of me knows too many secrets, and he can also control the power of the ocean. Could it be that the sea god really exists?

With the birth of the White Star, the ancient weapon Poseidon re-entered the world, prompting the sea god to no longer remain hidden and descend to earth to oversee the situation.

This logic is surprisingly reasonable.

Thinking of this, Neptune's gaze towards Tianxing held even more respect, though a lingering doubt remained in his heart—

What exactly does the so-called Third World refer to?

Tianxing noticed the change in Neptune's expression and silently made a mental note of it. Using information asymmetry to pretend to be a charlatan—this tactic was indeed quite effective.

He turned to Otohime and asked, "Would you like to live on the surface?"

Otohime's eyes lit up.

"That's been the wish of our fish-men for hundreds of years." Her voice wasn't loud, but it carried an undisguised fervor.

"It's not difficult to go ashore and live alone. The most important thing is to find a place that is willing to accept you fish-men to live together."

"I know a good place, I'll tell you when the time is right."

"Furthermore—" he paused briefly, "I will take care of Shirahoshi's future education."

Neptune understood immediately; they had indeed come for his subordinates.

Lord Poseidon, you truly have put in a lot of effort...
