The Black Duke of the Pirate

"Where is this?" Luffy shook his head, his eyes were very surprised.

"There must be a general controller here, wait for me, I'll go look for it."

"There is a sound that keeps ringing."

At this time, Sanji suddenly said.

"sound?"

Everyone was stunned for a moment, "What's the sound? Why didn't I hear it?"

Even Luffy didn't hear it.

Sanji felt that the sound was like a rumbling tsunami, rushing toward his ears.

"there!"

Sanji immediately pointed in the direction of darkness in the distance.

"Let's go over and have a look."

The closer Sanji got, the stronger the sound in his ears became.

Soon after, everyone came to a location blocked by an iron gate.

"I'll knock down this iron gate." Luffy said immediately, but was stopped by Franky.

"Wait a minute, Luffy, this iron gate is mixed with sea stone, so users with abilities cannot cause damage."

"Then leave it to me and watch me cut him into pieces!"

Zoro showed a confident smile, and the Yama in his hand suddenly passed through, and the iron door mixed with seastone material broke immediately.

"boom!"

Suddenly, a violent roar rang out, and everyone quickly covered their ears, but Sanji's power was so powerful that he didn't react at all to the sudden roar, and his head felt like a needle prick.

"Sanji, are you okay?"

Luffy immediately shouted worriedly.

Sanji shook his head, and after breathing quickly for a few times, he recovered slightly: "It's okay, this voice is too powerful."

After the baptism of sound just now, everyone has become accustomed to this roar.

"What is this sound?" Nami asked in surprise.

"This is the sound wave caused by the rotation of the machine. There must be a terrifying machine running inside."

Franky said, he was indescribably shocked. It was unbelievable that there was such a machine running all the time in this underground space.

The light on Franky's body shone, and soon he entered a huge room. A roaring engine appeared in the room, roaring like a wild beast.

"The sound insulation effect is really amazing. You can't hear the sound of this machine at all from outside, but the sound of the machine inside is so strong."

Brooke said.

"I have never seen this kind of sound insulation material." Frankie shook his head and said, at least in the technological knowledge he had learned, there had never been a material that could achieve such a terrifying sound insulation effect.

"It is indeed this thing!" Franky said in surprise.

"There's another room over there."

Luffy said suddenly, and quickly ran towards the room.

Others noticed, too.

"Luffy, don't move!"

After seeing Luffy rushing into the room and preparing to touch a host device, Franky immediately stopped him.

Luffy stopped what he was doing and looked at Franky in confusion.

"Don't touch this equipment. Keep it in its most original state. I want to study it carefully. It may have an important mechanism that can control the entire underground space."

Everyone in the Straw Hat Pirates walked in. After closing the door, the sound of the equipment outside could no longer be heard.

Now everyone listens to Frankie's arrangements.

Franky scanned the device for a long time, then a small steel claw appeared in his huge palm, and he searched for the densely packed buttons. After a while, he gently pressed one of the buttons.

Click...a crisp sound sounded, and the device seemed to be started.

After seeing this scene, everyone was overjoyed.

Beep beep beep...the lights in the room turned on immediately, and then the lights in the entire underground space also turned on at the same time.

"Warning, Human Secret Base No. 003 has been activated..."

"Warning, Human Secret Base No. 003 has been activated..."

"Warning, Human Secret Base No. 003 has been activated..."

Three consecutive hollow mechanical sounds sounded.

"This... doesn't seem to be something from our world."

After Frankie looked at it for a long time, he gradually understood.

The hollow echo of machinery kept coming to his ears.

Human secret base No. 003...

"What the hell is this?"

Before he finished speaking, the screen on the host lit up, and then a young man appeared.

The man has a Chinese character face, short black hair, and is wearing a very weird black suit with five buttons on the chest, four square pockets, and a stand-up lapel at the collar.

This black suit is very weird, but it looks beautiful, elegant and stable, which only adds to its elegant temperament.

"I am Wang Shen, the supreme commander of Human Secret Base No. 003."

Suddenly, the man in the picture said something.

"Did this guy speak?"

Luffy asked in surprise.

"This is a photo, similar to the function of the video phone bug." French said.

"Wang Shen... I seem to have heard of this name somewhere." Brooke said suddenly, but then shook his head, "No, it's not that the names are the same, but that the names are similar."

"Such a name seems to be rare."

"By the way, I remembered." Brooke said suddenly.

"Fifty-two years ago, I once met a young man on the first half of the Grand Route. His name was Wang Zhi."

"Wang Zhi..."

"Isn't that the crew of Rocks Pirates back then?"

Robin suddenly said, she is a historian, so she naturally knows these famous pirates in the history of pirates.

"The names are basically the same."

Robin's eyes scanned the room, but suddenly he found a line of text.

"This is... what Roger left."

"Roger, the Pirate King, once came here."

Just as Robin finished speaking, Wang Shen's voice continued to come from the screen:

"Welcome to Narcissus Base. Narcissus is a beautiful planet. I like it there very much..."

"So is this Narcissus Island?"

Robin looked slightly sideways, staring at the face of the handsome man on the screen.

She suddenly thought of something again, so she took out four pieces of text with directions.

"This is the outpost..."

"What outpost?" Franky asked.

"Outpost of the Final Island!"

In other words, the next island is the final island, the island that Roger visited back then.

After hearing this, Luffy immediately laughed: "Yeah, Pirate King, here I come..."

"Don't be happy too early."

Robin gave him a basin of cold water.

"That island... is under the sea!!!"

"What?"

Everyone was extremely shocked.

"There are many pirates in the New World, and there are pirates in every corner. Think about it, if it is on the sea, how come there is no information about the final island."

"The location pointed by the four coordinate texts is exactly the bottom of the sea!"

"Like Fishman Island?"

"Maybe..."

At this moment, Franky's eyes became serious and he said in a deep voice: "Luffy, I discovered a major secret. It is a huge secret that we have never imagined."
