Pluton has been sleeping quietly here for over eight hundred years.

The emerald green moss covering the dark hull is a testament to this long period of time.

Sirius and his gang were on the deck of this large, dark ship.

Black stepped forward and approached the entrance to the cabin.

The massive, tightly closed metal gate was, of course, covered in thick moss, a testament to the vast passage of time.

A laser beam shot out from Black's finger, slicing downwards and cutting through all the moss blocking the door crack.

Then he pushed the door open.

Only.

The door wasn't locked; with just a gentle push, the metal door swung open, revealing a sight that hadn't been seen for eight hundred years to Sirius and the others.

The interior was surprisingly bright, with bright lights casting a glow on the wide, simply decorated metal passageway.

"Let's go in and take a look."

Sirius the lead.

"You got in so easily?" Luo was somewhat surprised. "I thought the door would be tightly closed, and we would have to go through some tests before we could finally get in."

"How could this be?"

Sirius casually remarked, "Pluton is a gift left by the people of the past for those of the future; simply being here has already completed the test."

"Anyway, we're finally in, so Sirius," Jack looked at Sirius, "What's next?"

Jack asked Sirius, Sirius asked Black, "Black, do you know how to get there?"

"Certainly."

Black nodded without hesitation.

He had studied the blueprints for Pluton and was very clear about Pluton internal structure.

"Let's go straight to the power room."

Black led the way.

The group followed him along the wide passageway, then took the elevator down to the elevator lobby.

Inside the elevator, Maria said, "Has this ship really been buried at the bottom of the sea for over eight hundred years? Not only the lights, but even the elevator still works!"

Sirius laughed and said, "Didn't Black say that Pluton's power plant is the most advanced technology?"

"That's right,"

Black nodded. "This is technology akin to a perpetual motion machine; the energy source is virtually inexhaustible, so eight hundred years is nothing."

"That's amazing," Maria exclaimed sincerely.

That is indeed a remarkable technology.

This is what Sirius and Black are now dreaming of.

Soon, the group arrived at one of Pluton's levels, in front of an exceptionally large steel door.

A huge skull is carved above the door.

"Huh? A skull?"

Yamato was taken aback. "Could it be that Pluton was once a pirate ship?"

"Fool,"

Sirius laughed. "You don't need to think to know this is a danger sign, do you?"

"It is indeed very dangerous. If the power reactor goes berserk, even a huge island like Alabasta could be blown to bits."

Black walked up to the door and pressed several buttons on a small screen on it.

Click.

The heavy metal door slowly opened.

The scene inside the door was revealed.

A massive, silvery-white metal pillar, tens of meters thick, stood silently in the spacious room, directly connected to the ceiling.

Although it is a metal pillar, its smooth surface is filled with a shimmering light.

The entire room was built around this pillar, with a spiral staircase running up the circular wall.

"Huh? Is it that dangerous?"

Yamato followed Black into the power room, his eyes Yamato surprise.

If they can blow up a giant island like Alabasta, then none of them will escape if it explodes.

"In fact, Pluton' final resort was self-destruction."

Black said, "The reactor was designed with an explosive device attached; its self-destruction is even more powerful than a berserk explosion."

"So,"

Luo let out a deep sigh of relief, and then he said, "What kind of enemy did they face back then?"

Pluton is already so powerful that it takes three Ancient Weapons to fight him. What kind of monster could he be?

Unbelievable.

"We'll know everything when we get to Laugh Tale."

Sirius smiled.

No matter how curious you are now, it's all in vain.

Roger took all the truth to Laugh Tale.

"Black, go do what you want to do," Sirius said.

Black nodded and said, "It is indeed dangerous to have a running power plant, but if you stop it, the outcome is quite different."

He led everyone up the spiral staircase to a platform connected to the power furnace, where several machines were piled up.

Black walked over and fiddled with the controls for a while, then pulled on one of the handles.

Click.

The shimmering light on the surface of the power furnace began to fade.

Apart from that, there have been no other changes.

"Has the reactor been shut down?" Jack looked around. "But the lights are still on."

"The backup power supply has been activated automatically."

Black casually remarked, "Pluton's energy storage technology is far superior to Sirius '."

He operated the machine again, and a crack appeared in the power furnace, then a door opened.

I'll be right back.

Black dashed through the door.

He returned very quickly, in just five minutes.

"All done?" Sirius asked.

"Kindness."

Black took out a small test tube.

The test tube was filled to the brim with a crystal-clear liquid, so clear it looked almost like water.

"I need to analyze these materials," Black said, "To see what their individual properties are."

"Did the name change during historical shifts prevent me from finding the same materials, or do they simply not exist in the sea?"

"If I can't find the materials, I can only try to see if I can use similar materials as substitutes."

"It's up to you now."

Sirius nodded happily.

Black is still an accomplished materials scientist and chemist.

After carefully putting the test tube away, Black restarted the power furnace.

Then Sirius and his group wandered around inside Pluton.

Pluton is enormous, stretching for thousands of meters from front to back. Although not as long as Moria's Thriller Bark, its interior space is still vast, making it a true sea fortress.

However, the interior of this enormous ship appeared completely empty.

The weapons and equipment were complete, but no documents or records were found, and the idea of glimpsing the truth of eight hundred years ago was immediately thwarted.

"Then, let's go back."

Sirius was not disappointed.

As I said before, everything is already on the Final Island.

After leaving Pluton, they returned to the Sirius.

"Let's go, Brook, now we'll take you away from this area," Sirius said with a smile.

"I've been waiting for this for ages."
