Under Cardo's questioning, the old man began to tell the story of Skull Rock Island.

"About 10,000 years ago, people found the carcass of a sea turtle on the surface of the sea, this turtle is as huge as an island, the thickness of the shell alone is hundreds of meters, no one knows where the turtle came from, how it grew so big, and why it died."

"The body of the turtle floated around the world, until one day it knocked down a volcano on the sea, the volcano that was violently hit erupted instantly, and the dust filled the world, like the end of the world, the eruption of the volcano lasted for half a month, half a month later, there were bold pirates who went there to check, the body of the turtle had disappeared, and people at that time thought that the body had been burned to ashes, who knows, after five thousand years, the body of the turtle reappeared, leaving only an empty turtle shell floating on the sea, It's like a giant floating island."

"At that time, the inhabitants of an island moved from their hometown to escape the persecution of pirates and moved to live on the empty shell of the turtle, but for some reason, the turtle's shell only had rocks and no animals or plants, so this island was also called Skull Rock Island."

"A few years later, the turtle's shell disappeared from the sea again, some say it floated to the sea where no one knows, some say it has sunk to the bottom of the sea, until three hundred years ago, the turtle's shell reappeared, there is no trace of human beings on it, but in the shell of the giant turtle appeared a special plant, this plant is called crystal vine, because it is as transparent as crystal, and it contains a lot of water, after cutting a section, it can be eaten directly."

"After the discovery of the crystal vine, some people in the desert area still want to transplant some back, using the crystal vine as a water source, who knows that this plant can only survive on Skull Rock Island, and cannot be transplanted at all, because there is no use value, so people can only let Skull Rock Island drift on the sea."

"Until the appearance of a group of pirates, this group of pirates belonged to the most famous pirate group at the time, the 'Naga Pirates', whose fleet was routed by the navy, and fled to Skull Rock Island under the leadership of their leader Naga, because it was secluded enough and there were crystal vines as a water source, they settled on this island."

"After a long time, the original Naga Pirates have all died, leaving only their descendants, two hundred years ago, their descendants established a Naga kingdom on Skull Rock Island, and the king is Naga's direct grandson."

"In the past two hundred years, the kingdom of Naga has gradually become accepted, and even became the most famous tourist destination for a time, many people who want to see the remains of giant sea turtles will visit here, the only thing that is not beautiful is that Skull Rock Island will always float around, no one can predict the direction in which it will float, and sometimes it will even float into the windless zone for years, because this has happened so many times, so no one will be worried."

"Until twenty years ago, this island drifted back into the windless sea, the people of the Naga Kingdom have become accustomed to it, and do not take these things seriously, who knows that this time the floating actually lasted for twenty years, during which in addition to being able to fall from the shipwreck to the population of Skull Rock Island, knowing some news from the outside world, this place has become similar to the primitive society, and even the clothes are gradually decreasing, and some ordinary residents can only find other ways to cover their bodies."

"Is that the kind of animal skin you are wearing?" asked Cardo, pointing to the unknown animal skin on the old man's body.

"Hehe, yes, I am also a native of the Naga Kingdom, and I have been living here since this island entered the windless zone" The old man smiled and picked up his cigarette pouch again and smoked: "What I just told you is the legend of this island, and the credibility is not high, but it is true that this island is a turtle corpse, and I have seen the bones of the turtle with my own eyes" Speaking of this, a proud look appeared on the old man's face, as if it was an honorable thing to be able to see the bones of a turtle.

"By the way, what's that red crystal on this," Caldo asked, pointing to a large pile of glowing fiery red crystals on the rock wall at the top of the space.

"These are magma crystals, and they can be easily found where volcanoes have erupted, and they are almost as shiny as gemstones, but they are of no use at all except for illumination," the old man explained.

"And one last question, why is this place called Aquaman's Lair?" asked Cardo.

"Of course, it's because there are many sea kings here" Seeing Cardo's surprised look, the old man hurriedly explained: "But don't worry, these sea kings are blocked from the outside by the empty shells of sea turtles, and it is impossible to hurt the people inside, but because there are many large and small caves here, many sea kings like to survive and reproduce in these caves, and regard those caves as their own homes, so the residents of the island often enter these caves to hunt, get some sea king meat, and improve their lives" A smile appeared on the old man's face, As if reminiscing, he said, "Back then, I was an expert hunter, and together with my buddies, I could catch about two or three sea kings in a day, which was one of the best in the entire Skull Rock Island."

"Is there a shortage of meat here" Cardo took out a pink transparent rattan from a passerby's backpack, stuffed it into his mouth and sucked it up, sure enough, this rattan contains a lot of water, and there is a hint of sweet taste, except for the crystal vine that the old man said, this thing has a pink color, and the crystal vine is no different, it should be a new variety of crystal vine.

"Yes, if you want to eat meat, you can only work hard, or risk your life to go out hunting" The old man glanced at the crystal vine in Cardo's hand, and said secretly, this kid is very fast, and he doesn't know where to get the pink crystal vine, this is a high-end drink.

"Gollum"

Cardo rubbed his stomach and said to the old man, "Uncle, can you tell me where I can catch the sea kings, I'm dying of hunger."

"Hehe, if you're really hungry, I can treat you to a meal," said the old man with a smile.

The thick-skinned Cardo didn't say a word, and followed the old man to the cave where he lived.

The cave looked rather rudimentary, a rocky bed with some worn animal skins for a quilt, a larger pile of rocks and a few smaller piles for tables and chairs, and nothing else.

"People are too old to work, so they can only live in such a humble place," the old man asked Cardo to sit on the stone pier, and ran to the corner of the cave, where he made a place that looked a little like a stove.

Cardo, who was in a hurry to eat, did not sit still, but stepped forward to help, hoping that with his help, he could eat earlier.

The old man took out a small piece of jelly-like something out of nowhere, lit it with a flint, and explained to the surprised Cardo: "This is manatee fat, a small piece can burn for a long time, and the inhabitants of Skull Rock Island use this thing to make fires."

"This world is really full of wonders" Cardo secretly sighed, in the world of One Piece, there are indeed many strange things, which he can't even think of on Earth.

"Hey, let's try it," said the old man as if he were nervous as if he were nervous after cooking a lot of sticky things.

The hungry Cardo didn't think much about it, picked up the stone spoon, and ate it in a big gulp.

"Don't you have any other uncomfortable feelings?" The old man stuck his head in front of Cardo and stared at him.

"No, it's delicious," Cardo puffed out his mouth, a little puzzled, how could the old man ask such a question.

"Oh, it turns out that it can really be eaten" The old man breathed a sigh of relief and said, "I didn't expect that crystal vines and kelp grass can really be eaten as rice when mixed together."

"What!" Cardo almost spit out the food in his mouth, and there were black lines all over his head.

"Nothing, nothing" The old man waved his hand again and again, apologetically: "I heard that this is a new way of eating invented by the victim, he said that he is the top chef in the world, he likes to crazy research on various ingredients and new cooking methods, after coming here, he invented this way of eating, although I heard that it can indeed be eaten, but I am a little worried, so I specially asked you to try."

"I was used as a guinea pig!" Cardo didn't feel angry, he was used to it, and Sanchi often made strange things for himself to try.

"Wait, Sanchi" Cardo suddenly woke up, the new victim, is still the top chef from all over the world, and he likes to study new ways to eat the most! Is this guy obviously Sanchi's bastard, I didn't expect to be his guinea pig again unintentionally.

"Old fellow, tell me quickly, what is the name of that chef, where he went, tell me, and I will forgive you, otherwise, just by the fact that you treat me as an experiment, I will tear down your broken nest" Cardo, who was eager to know where Sanji was, spewed out a series of questions, and even a little disrespectful in his tone.

"Ahem" the old man said embarrassedly: "It seems to be called, business opportunity, pheasant, or Sanchi, I can't remember clearly, but I heard that he was invited by the king to go to the palace to cook food."

After eating the rest of the paste in one go, Cardo asked the direction of the palace and ran out of the cave, leaving the old man with a strange look behind his buttocks.
