One Piece: Trainers on the Straw Hat Pirates

He immediately summoned a signpost fly.

No language communication is required.

Having already visited several Celestial Dragon castles, they followed the trail of flying insects with practiced ease, heading towards the Celestial Dragon's treasure vault.

……

……

Meanwhile, on the other side...

"Another Devil Fruit!?"

A glint flashed in Sanji's eyes as he looked at the strangely shaped, black-and-white fruit that Apoo had handed him.

Since entering Mary Geoise, this is the sixth Devil Fruit they have discovered in the Celestial Dragons' treasury!

On average, there is one Devil Fruit in almost every two Celestial Dragon treasuries.

In addition, there are countless precious swords and spears, and rare treasures!

The treasures, worth hundreds of millions, could be described as commonplace items in the Celestial Dragons' treasury.

This shows just how extravagant the Celestial Dragons' lives were.

The next second, Sanji raised his hand and threw the Devil Fruit in his hand directly at Capone, who had already transformed into a castle, and it landed precisely in a room specifically for collecting Devil Fruits.

"I wonder if there's a Devil Fruit that would suit that green algae-headed guy..."

Sanji murmured softly, his gaze sweeping over the mountain of treasure.

Although the Speed-Speed ​​Fruit's powerful abilities allowed him to gain the upper hand in his battles with Zoro, it was precisely because of this that Sanji became even more aware of just how terrifying Zoro's talent truly was!

Even if Zoro gains Devil Fruit powers, he could very well change the current situation and once again completely overwhelm him in terms of combat strength.

But Sanji still hopes to compete fairly with Zoro.

As time slowly passed, the gold and jewels in the entire vault were quickly packed into Capone's body castle by the group of supernovas.

After doing all this, Sanji frowned slightly, pondered for a moment, and then said to the Supernovas:

"This can't go on!"

"We don't have much time; the Celestial Dragons will soon discover the anomaly."

"We must be selective in what we take from the treasure vaults, only taking the precious items that are easy to access."

"We understand."

The Supernovas nodded in agreement, understanding Sanji's concerns as well.

only……

The thought of having mountains of gold and silver treasures right before their eyes, yet having to pretend not to see them, filled them with sorrow.

However, Sanji could not empathize with their pain at all.

"Alright, let's tidy up and get ready for the next place!"

With a wave of his hand, Sanji led the Supernovas away from the castle.

Under the cover of night, they quickly made their way towards the adjacent castle area.

……

……

Pangu City, the residence of the Celestial Dragon Clan Chief.

"Hey, Nami, we've been walking for ages, haven't we found the treasure yet?!"

"Shh! Stop making noise!!!"

In the spacious, luxurious corridor, Luffy, who had been walking cautiously with his head up every step for half a day, suddenly looked up and revealed an impatient expression.

From the moment they entered Pangu City, they had been hiding and constantly on guard against the various patrolling guards.

That's nothing.

The key is……

From time to time, news of Usopp's team and Sanji's team's victories would be broadcast on their telepathic public channel!

One minute they've freed dozens of slaves here, the next they've discovered a Devil Fruit or some other treasure over there...

They receive such a message almost every ten minutes or so.

On the other hand, Luffy's four crew members had been in Pangaea for over an hour, and they were either dodging patrols or climbing various pipes.

This kind of drop in status was a huge blow to Luffy!

In fact, Luffy wasn't the only one who felt bored and annoyed.

Nami is the same!

Even though the location of the treasure, as indicated in my mind, is not far ahead, I must proceed slowly...

This tormented her even more than the recurring images of finding treasure in her mind.

But there was no other way.

Pangu City is absolutely enormous!

In some respects, the size of this building is comparable to that of some small islands or countries.

Without being able to use the mobile mechanisms inside Pangu City, reaching the location where the treasure is imprisoned is truly a difficult task.

Fortunately, just then...

A streak of pale green ghostly fire suddenly appeared from the ceiling and crashed directly into Luffy's skeletal body.

"Brook is back!"

Upon seeing this, Luffy's eyes suddenly lit up.

Nami and Robin also quickly turned their gazes over.

"Hehehe~"

"Sorry to keep you all waiting."

Brook, now back, chuckled softly and apologized to his companions.

Nami, who had just been trying to quiet Luffy, suddenly asked excitedly:

"How's the situation?!"

"Is the Celestial Dragons' treasure vault guarded?!"

After more than an hour of "long journey", they have finally arrived at the destination marked by Nami's picking-up ability.

However, this area is very strange. The building materials seem to have been specially treated, as they can actually block the exploration of spiritual power!

Not only could their Observation Haki not detect anything above, but even Robin's psychic powers were powerless against it.

fortunately……

In addition to their mental abilities, they also have additional methods of detection.

That is Brook, who possesses a three-dimensional soul!

only……

When asked by Nami, Brook first nodded, then immediately shook his head.

This scene made Nami and the others instantly feel strange.

But Brook explained:

"There are indeed no guards up there, but that room upstairs isn't some Celestial Dragon's treasure vault..."

"It's more like... a research base!"

"A research base!?"

Upon hearing this answer, Nami and Robin exchanged a glance, both seeing a hint of confusion in each other's eyes.

Robin even spoke directly:

"A research base capable of isolating mental energy... this is very likely an important experimental area for the World Government."

"So Brook, did you see what treasure Nami sensed!?"

"Ah."

Upon hearing this, the will-o'-the-wisp in Brook's skull eye sockets flickered suddenly.

"If nothing unexpected happens, I think Nami sensed it..."

"It must be the Devil Fruit from that room!!!"

"There's a whole box of Devil Fruits in that room!"

"And some of them were even placed directly on the table."

"If the labels on the table are correct, the names of those Devil Fruits are..."

"Zoan type, Bird-Bird Fruit, Mythical Zoan type, Suzaku form;"

"Zoan type, Cat-Cat Fruit, Mythical Zoan, White Tiger form;"

"Zoan type, Snake-Snake Fruit, Mythical Zoan type, Black Tortoise form;"

"as well as……"

"Zoan Type, Ox-Ox Fruit, Mythical Zoan Type, Kirin Form!!!"

"Suzaku, Byakko, Genbu..." Robin's eyes lit up upon hearing Brook's introduction, "plus Kaido's Azure Dragon Fruit..."

"Aren't these the four divine beasts that Crimson introduced before!?"

"Red said that the Azure Dragon Fruit originally belonged to the Celestial Dragons, but it ended up abroad due to an accident."

"So it turns out that the Celestial Dragons collected these powerful Mythical Zoan fruits quite early on."

"Four Mythical Zoan Devil Fruits and a box of Devil Fruits with unknown abilities?!"

"Nami's pickup ability is way too powerful!?"
