"The most powerful pirate hunter in the East China Sea? When did such a pirate hunter appear in the East China Sea?" Kurokas stared at Qin Shou and looked at him for a while.

Gailmore further explained, saying, "You don't know that he destroyed the Creek Pirates, the Dragon Pirates and the Bucky Pirates in the East China Sea. This strength is recognized by everyone. We are also lucky this time, and we escaped by chance with him."

Kurokas nodded thoughtfully, then brought a few chairs from the house for Qin Shou, Gaelmore and others to sit down. After sitting down, the group started chatting like this.

"By the way, I have to explain something to you. I am only responsible for your destination this time. If you return to the East China Sea, you will go back by yourself." Qin Shou said to Gaelmore.

Gailmore seemed to have heard of this from Hans, and nodded in no particular strangeness.

At this time, Isis thought of something and suddenly asked: "Captain Gael, according to my observation of the channel just now, it should be very troublesome for you caravans like the East China Sea who are traveling from the East China Sea to the Great Route to sell things and purchase them back to the East China Sea, right?"

"Girl, what do you mean? Can you make it clearer?" Gaelmore didn't seem to understand what Isis meant very much.

Isis expressed her doubts and said, "According to the way Mount Leverde, it is impossible to return the same route. Moreover, I have studied the great route before and heard that the currents above are very harsh and only record pointers, but record pointers only point to the next island. So if you want to go back, it is impossible to go all the way along the pointer and circle the great route for a week? That's why I said that it's very troublesome for you to go back and forth."

In fact, this is also Qin Shou's doubt. The mountain of Mount Levas is so high that the ship caves in the East China Sea or other seas enter great routes, such as the power of ocean currents, and now it is impossible to go backwards, right? This is almost impossible!

Galemore heard Isis's doubts and couldn't help but hang his big pipe and grinned: "Girl, it seems that you don't know enough about this great route. We are a caravan, and our general delivery purpose is just the island closest to Twin Cape. So we are not far away, and it is not difficult to come back."

"Even if you don't go far...how did the caravan come back? If it was a compass, it didn't seem to work." Isis frowned. She still had a lot of doubts in her heart, who didn't know much about the world.

Kurocas, who had not spoken at this time, finally spoke. He pointed at the towering lighthouse in the mountains with his index finger and said, "Little girl, what do you think is the point of setting up a lighthouse here in Gemini Cape?"

What is a lighthouse? It is a tower-shaped luminous beacon built near key parts of the waterway. A lighthouse is a fixed beacon used to guide ships to sail or indicate dangerous areas. Modern large lighthouse structures have good living and communication facilities for management personnel to live in, but there are also important lighthouses that are unguarded. According to different needs, different colors of lights and different types of fixed light or flashes are set. The range of lights is generally 1,525 nautical miles.

So the lighthouse is the road and guiding light that illuminates the waterway and boards the ships' journey!

When I heard this Isis suddenly realized: "So that's it... If there is a lighthouse and you can't walk far, you can find the way back when the compass fails, but I still have the last doubt... If there are only two ways to return to the East China Sea from here, one is the waterway we just came over, and the other is the windless belt. The ocean currents that go back are countercurrents and cannot be passed, but if you walk in the windless belt, you will be attacked by the sea kings, then it is..."

Gailmore took a sip of tea and moistened his throat before continuing to explain: "Don't say that a caravan like us would be very dangerous to walk on the windless belt. Even if it hits the naval warship with the most powerful cannon, it is impossible to pass through the windless belt every time. So there is definitely no way to walk on the windless belt."

Qin Shou was also Mo Mo listening, and when he heard this, he couldn't help but speak, "That's what we did? How did we do it?"

"Haha...so I said you young people have not enough experience. Now I'll ask you what are the factors that affect ocean currents?" Gailmore asked a question like a geography teacher.

Isis thought for a while and said, "The main reason should be the wind, then the density and air pressure of the sea breeze, etc.."

Gailmore shook his head and said, "So you only see the surface, but you ignore the most important factor."

After saying that, Galemore pointed at the top of his head.

Isis, Qin Shou and others all looked up at the sky and immediately understood.

"Is it... it's because of the moon?" Isis suddenly realized.

"Yes, the tidal power generated by the moon's tidal force is more than you imagined. The water flow of Mount Levers is not always like this. It actually flows countercurrently! Whenever the moon is full, the sea water from Gemini to Mount Levers will flow backwards and flow down the other four sea areas respectively. Our caravan uses the help of this time to return the same route. So the weather in our caravan's sea has the greatest impact on us. But this time the weather is obviously very good!" Galmore explained.

Isis's doubts were all resolved, and Qin Shou also gained knowledge. These were all things that were not mentioned in the original work. I have to say that One Piece's time is really magical.

"In this way, the most round moon is the most rounded and gravitational force that reaches its maximum is from July to August every year? No wonder there are so many merchant ships in Luoge Town at this time, all waiting for this golden time to enter the great route and return quickly." Qin Shou also understood many of them.

"Yes, it's probably from July to September... This time is golden time for ships running on the Great Route and the East China Sea or other seas. Hans and I only come once a year, and it has been back and forth more than a dozen times." Gailmore said as he felt a little excited and smoked a few big smokes.
