"Sun thief! It's kind of back! ”

Ian slapped the side of the ship and yelled at the Pique Pirates who were already far away, trying to turn on the taunt mode and get the guys to turn back.

The consequences of this are...... The Pico Pirates' ship is running faster......

The sailors on the ship looked at each other, and couldn't understand what Ian meant, as a caravan, those pirates ran away, and they still wanted each other to run, how could there be a reason to call each other back?

Bill pulled Raian from behind, shook his head and said: "Forget it, you won't come back, don't look at Pixar's obesity, you think he's really stupid, no one is stupid to be the captain of a pirate ship, since he has made up his mind to escape, it is impossible to be scolded by you and turn back, your duty is only to protect ships and cargo, there is no need to be too entangled with pirates." ”

was persuaded by Bill like this, and Ian could only give up stupidly.

Seeing that his persuasion was effective, Bill finally showed a little smile and said, "Don't worry, on the great route, everything is lacking, but the most lacking may be pirates, if you want to catch pirates, there will be opportunities in the future." ”

Since they crossed Upside Down Mountain while Rab was diving into the sea, the remaining eleven merchant ships arrived safely, but because the flagship mast that Ian was riding on was damaged, all the ships of the caravan docked on the shore of the lighthouse at Twin Capes, ready to wait for the flagship to repair the mast before going on the road together.

It wouldn't take long to repair the mast, but it would take at least an afternoon to stay here, so Ian followed Bill to the shore.

"Old fellow! Old man, are you there? Here I go again! "There was a house next to the lighthouse on the shore, and as soon as Bill came ashore, he shouted at the house, which made Ian stunned for a moment: Bill can't he be an old man who screams, can't he be a Colux?

Ian couldn't remember the name of this man, it seemed like that, Ian only remembered that he was the lighthouse keeper of the Twin Heads, but wasn't this tower keeper supposed to live in Rab's belly?

With Bill's shout, the door of the house opened, and an old man wearing a short-sleeved shirt with a petal-like head walked out, with glasses on the bridge of his nose, not who was Colux, as soon as he came out, he was stunned for a moment when he saw Bill, and then greeted: "Bill, you are here with the fleet again?" ”

"Yes! This is the last time! Bill laughed, and he was glad to see his old friend.

Ian stepped forward and asked Bill in a low voice, "Do you know this old man?" ”

"Of course!" Bill nodded and said, "I've gone back and forth a lot, so naturally I'll know each other." ”

As Ian and Bill spoke, he didn't notice that Colex stared at his hat for a while, and then suddenly asked Bill, "Who is this young man?" ”

"Oh! He's the most famous pirate hunter in our East China Sea right now! Bill hurriedly introduced: "Several of the pirates with the highest bounties in the East China Sea have all been caught by him, and this time we are also lucky to invite him to be the caravan guard." ”

Colex nodded, didn't say anything, moved a few chairs out, and let Ian sit down.

At this moment, a voice sounded very carefully in the back, saying, "I...... Can I sit here and take a break? ”

Ian looked back and found that it was Roland Gale, at this time, where was he still the kind of invincible when he first got on the ship? When he was attacked by the Pique Pirates before, this guy had been hiding in the cabin shivering, and he didn't dare to show his face, but now that he was finally safe, he dared to go ashore to breathe.

Thinking about this encounter into the great voyage, I am afraid that it will stimulate this little nobleman who has not seen much of the outside world.

Ian ignored him, but Bill gave him a chair and poured him a glass of water to sit down and rest.

Colex and Bill chatted, and what they said was the scene when they met before, and older people just like this kind of memory, while Ian listened on the sidelines, and suddenly asked Bill suspiciously: "Bill, I heard that the Great Voyage can enter or exit, is this true?" ”

In fact, he has long had doubts, this time he came with the merchant ship, listening to Bill's meaning, after they sold the goods, they had to buy and then return to the East China Sea, according to the way of the upside-down mountain, Ian always wanted to ask them how to go back, this question has been holding in his heart for a long time, and now he finally took advantage of the fact that Colex was also there, and asked it.

"Can you get in or out? Who are you listening to? Bill asked, surprised.

"Isn't it?" Ian said: "I heard that on the Great Route, the climate and currents are very chaotic, the only thing I can trust is the record pointer, but the record pointer will only point to the next island, if you want to go back, you can't follow the pointer all the way and go around the Great Route, right?" ”

In fact, Ian's so-called hearing is just from his memory when he used to read comics, and this is what Colux said in front of him, so Ian asked here, in fact, he also wanted to hear how Colux answered.

"You're thinking wrong!" Bill grinned and said, "We are a caravan, we are not capable of going deep into the Great Voyage, and the destination of our caravan is only the nearest island to the Twin Capes, there are seven such islands, which are the starting islands of the seven routes on the Great Voyage." ”

"Even if you can't go far, how are you going to get back?" Ian still frowned and said, "Twin Cape is not an island, so it is impossible for the record pointer to point here, right?" ”

Hearing Ian's question, Colex finally spoke, and he pointed with his thumb to the lighthouse standing high in the mountains behind him, and then took over and said, "Young man, if you can really get in and out, then what do you think the lighthouse set up at this end of the Twin Capes is for?" ”

"Isn't it to guide the ships that come down from the Upside Down Mountain?" Ian Road.

"Wrong, there is one purpose to guide the ships coming down from the upside-down mountain, and another purpose, to guide the ships returning from the starting islands to the Twin Capes!" "It's true that the Twin Pointers are not islands, so the recording pointer will not be affected to point to the Twin Heads, but do you think that without the recording pointer, people will not be able to sail at all?" ”

"As long as the lights of the lighthouse are not extinguished, the ships returning from the Twin Headlands will not get lost at sea!" Colex said: "This has been handed down from hundreds of years ago, human wisdom! At a time when people had not yet invented the record pointer, navigators relied on the guidance of lighthouses. ”

Ian understood a little and nodded, but then asked, "Even if you can return to Twin Cape from the starting island, how do you get out?" It's impossible to walk in the windless belt, right? ”

"Indeed, a caravan like ours can't go through the windless belt!" Bill said: "The windless zone is very dangerous, and even the warships of the navy may not dare to guarantee that they can pass through the windless zone smoothly every time, let alone our ordinary merchant ships, but...... We've got a solution! ”

As he said this, Bill winked his eyes at Ian and asked, "Ian, what do you think are the reasons that affect the tides in the ocean?" ”

Ian thought for a moment and said, "Climate, temperature, and geographical factors......

Bill shook his head and said, "What you said is one of the factors, but you forgot the most important one!" ”

With that, he pointed to the sky.

Ian raised his head, looked at the sky with a puzzled face, and said, "Heaven? You're not talking about rain...... Sun...... Yes! I see, it's the moon! ”

"Yes!" Bill smiled and nodded: "It's the moon, the tides of the sea, in fact, are caused by the gravitational pull of the moon, if there is no moon, you can't see the waves of the sea, you can only see the dead water." ”

Colox also spoke: "The water flow of the Upside Down Mountain, in fact, does not flow like this all the time, it actually flows against the current, whenever the moon is full, when the gravitational pull of the moon reaches its maximum, the direction of the water flow of the Upside Down Mountain will turn around, rushing straight up from the twin headlands, and then diverging into four streams at the top of the mountain, flowing into four oceans respectively. ”

Ian's eyes widened when he heard this, and there was such a statement!?

He didn't know anything about it...... This real One Piece world is even more wonderful than he knows......

Looking at Ian's face, both Bill and Colux seemed to gain a sense of satisfaction, people who didn't know about the great voyage, or who didn't know much about it, usually had such a surprised expression after hearing this, as an old man, they liked to see this kind of expression the most.

"I'm not sure when the upside-down mountain is going against the current, but it's usually between the fifteenth and seventeenth of each month!" Bill explained to him: "When the time comes, the Upside Down Mountain will turn from the entrance to the exit of the Great Route, and those caravans like us who want to return will choose to come to the Twin Capes at this time, wait for the countercurrent to happen, and then return to the blue ocean." ”

"This is something that most caravans that have traveled through the Great Voyage know!" Colex said: "Some pirates who are halfway monks don't know this, or some people who are too deep into the great voyage and can't return to the Twin Capes, so if they want to break away from the great voyage and return to the four seas, they will take the risk to break into the windless zone, and the strong ones are good to say, maybe they can really break through, and if they are weak, they will be buried in the mouths of the large sea kings, so the statement that the great voyage can enter and exit is completely wrong." ”

It was rare for Ian to have someone to help him answer these doubts, so he listened to it with relish, and by the way, he also asked another question, saying, "On the great voyage, can you only take those seven fixed routes?" ”

"Not necessarily!" "The so-called fixed route is inaccurate, because it is only the direction that goes according to the record pointer, in fact, as long as you have a permanent pointer, you can jump from one island on the route to another, because the permanent pointer is not disturbed by the magnetic field of the other islands, it will always point to a certain island." ”

"Of course, making a permanent pointer is not easy!" Bill continued: "It is said that a very special process and principle is required to make a normal recording pointer Colux, but he can't make a permanent pointer!" So generally speaking, permanent pointers are very precious, and people who have permanent pointers will carry them carefully and will not show them to others. ”

However, before the words fell, a weak voice sounded behind everyone: "You don't mean this when you say permanent pointers, do you?" ”

Ian and the others were stunned for a moment, and turned their heads, only to find that it was Roland Gale, who had just come ashore, and at this moment he was holding a delicately made, hourglass-like thing in his hand, a round glass ball, which was held in place by a shelf supported by four small pillars, and in the glass ball, there was a suspended magnetic pointer.

Although it looks old, this is definitely a permanent pointer, because on the wooden sign facing Ian, a few letters can be seen very vaguely, and Ian carefully recognized it for a while, and then read it: "Ah...... Allah...... Alabastan!? ”

it!? This turned out to be a permanent pointer to Alabastan!?
