Chapter 81 (2/2)
In fact, Ian's so-called listening and speaking only comes from his memory when he used to read comics, and this is what coke said in front of him. So when Ian asks here, he also wants to hear Coke's answer.
”You are wrong!” Bill grinned: ”we are caravans. We can't go deep into the great route. Our caravans' destination is just the nearest island to Gemini headland. There are seven such islands, which are the starting islands of the seven routes on the great route.”
”Even if it's not far, how can you come back?” Ian frowned and said, ”Gemini cape is not an island. Can't the record pointer point here?”
When he heard Ian's question, Cox finally spoke. He pointed his thumb at the high lighthouse on the mountain behind him, and then said, ”young man, if you can really get in or out, what do you think the lighthouse at this end of Gemini cape is for?”
”Isn't it guiding the boat down from the upside down mountain?” Ian road.
”Wrong, it's only one purpose to guide the boat down from the upside down hill, and another purpose is to guide the boat back from the starting island to Gemini headland!” ”It's true that Gemini point is not an island, so the record pointer will not be affected. Point to Gemini Point, but do you think people can't sail without the record pointer?” Cox said
”As long as the light of the lighthouse is not out, the ships returning to Gemini Point will not lose their way at sea!” Cokes said: ”this is handed down from hundreds of years ago, human wisdom! At that time when people had not invented the recording pointer, navigators were guided by lighthouses
Ian understood a little, nodded, but then asked, ”even if you can return to Gemini promontory from the starting Island, how can you get out? It's impossible to walk in the windless zone, isn't it
”It's true that caravans like us can't walk in the windless zone!” Bill said: ”the windless zone is very dangerous. Even the warships equipped with hailou stone can't guarantee to pass through the windless zone every time, let alone our ordinary merchant ships. But we have our way!”
Speaking of this, Bill squinted at Ian and asked, ”Ian, what do you think are the reasons that affect ocean tides?”
Ian thought about it and said, ”climate, temperature and geographical factors.”
Bill shook his head and said, ”what you said is one of the factors, but you forget the most important one!”
Then he pointed to the sky.
Yi'an raised his head, looked at the sky with doubts and said, ”heaven? You don't mean rain or sun! I see. It's the moon
”Yes Bill nodded with a smile and said, ”it's the moon. The tides of the sea are actually caused by the gravity of the moon. If there is no moon, you will not see the surging waves of the sea. You will only see the dead water.”
Cokes also said: ”the water flow of the inverted mountain does not always flow like this. In fact, it goes against the current. Whenever the moon is full and the moon's gravity reaches its maximum, the water flow of the inverted mountain will turn around and rush up from the twin headlands. Then it will flow into four streams at the top of the mountain and flow to the four oceans respectively.”
Ian's eyes widened when he heard that. What's more!?
It was something he didn't know. The real world of the pirate king was more wonderful than what he knew
Looking at Ian's face, bill and Cox seem to have gained a sense of satisfaction. For those who don't know or know little about the great route, they usually have such a surprised expression after hearing about it. As an old man, what they like most is this expression.
”The time of reversing the mountain and the current is not sure, but it's usually between the 15th and the 17th of every month!” Bill explained to him: ”at that time, the upside down mountain will turn from the entrance to the exit of the great route. Caravans like us who want to return will choose to come to Gemini Cape at this time, waiting for the counter current to happen, and then they can return to the blue sea.”
”That's what most caravans who have traveled great routes know!” Cokes said: ”some half time monks don't know this, or some of them are too deep into the great sea route to return to Gemini headland. If they want to leave the great sea route and return to the four seas, they will venture into the windless zone. It's a good thing to say that if they are strong, they may be able to break out. If they are weak, they will be buried in the mouth of large sea kings, Therefore, it is totally wrong to say that the great route can enter but not exit. ”
Yi'an seldom had someone to help him answer these questions, so he listened with interest. By the way, he also asked another question and said, ”can we only take those seven fixed routes on the great route?”
”Not necessarily!” ”The so-called fixed route is not accurate, because it is only the direction according to the recording pointer. In fact, as long as you have a permanent pointer, you can jump from one island on one route to another, because the permanent pointer is not interfered by the magnetic field of other islands, it will always point to an island,” Cox said
”Of course, it's not easy to make a permanent pointer!” Bill then said: ”it's said that it needs a very special production process and principle, ordinary recording pointer coke can do, but he can't make a permanent pointer! So generally speaking, the permanent pointer is very precious. People who have permanent pointer will carry it carefully and will not show it to others easily. ”
However, the voice is not down, a weak voice behind the crowd sounded: ”you say the permanent pointer, do not mean this?”
Ian, they were all in a daze. They turned around and found that it was Roland Gail who had just come ashore. In his hand, he was holding a delicate, hourglass like thing, a round glass ball, which was fixed by a shelf supported by four small pillars. In the glass ball, there was a suspended magnetic pointer. Although it looks very old, it is definitely a permanent pointer, because on the side of the wooden card facing Ian, several letters can be seen vaguely. Ian carefully identified them for a while, and then read out: ”alaalabastan!” what the fuck!? This is actually a permanent pointer to alabastan!?
