Although Harus said that there are still many unruly guys and wandering pirates who will ignore the unspoken rules of the route and launch attacks, perhaps it was the luck of this voyage that was really good, so after setting off from Neidian Island, the "Kosi" never encountered a pirate ship again, but let him and Xiao Ya end up a few days of leisure.

However, what Xiao Ya didn't expect was that three days later, Lazar would come and ask him about the route with Harus, "Decide the direction of sailing, shouldn't this be your job captain?" "Anyway, the other party knows that he is a rookie, so there is no need to hide it.

"Oh, if it's just a boat, that's true," Lazar said, "but sailing on the Great Passage is never as simple as sailing a boat," he said with a wry smile on his face, "and we've been away from Neipoint Island for three days, and according to our records, we should have reached the midpoint between us and the next island, so it's up to you to decide whether we'll continue on to the next island, or turn to the open sea now." ”

"The former will sail along a route connected by three islands, just as we did earlier to the Inner Point Island, and then pass through two islands to reach the City of the Seven Waters; The latter will move away from the islands and head directly from the open sea to the City of the Seven Waters. ”

Although Xiao Ya is still a layman to navigation, but in connection with what he has heard in the past few days, he also understands that now this route is sailing along Pirate Island, according to the rules of the pirates, this can avoid the attack of some pirates, but it will also increase the chance of encountering pirates, whether there will be a battle depends more on whether the other party "abides by the rules"; The other route chooses to bypass and sail directly from the open sea to the City of Seven Waters, which will reduce the possibility of encountering pirate ships, but on the other hand, as long as you encounter pirates, there will definitely be conflicts!

In addition, the pirates encountered in the former are more "sitting households" who are active in the coastal sea, while the latter is not necessarily, only Xiao Ya knows that it includes but is not limited to: rookie pirates who do not know the great shipping routes, adventure groups that explore various secrets of the world, "supernova" pirates who are in batches of a year or several years, and pirates who plan to become the Seven Martial Seas...... The risks are different, and the amount of work he faces for bodyguards like Harus is of course different, so there is still a lot of say, so it is no wonder Lazar said that "on the great waterways, sailing is never just about driving a ship".

"Then which route is faster...... Before he finished speaking, Xiao Ya knew that he was stupid again, on the great channel, there was no faster or slower at all, "Oh, closer?" He tried to change his tune.

"Mr. Xiao Ya, you are really joking," but even Lazar, who has always maintained respect for Xiao Ya, couldn't help laughing, "On the great channel, you can't even determine the direction, the ship just follows the direction of the pointer, and as for the speed, it can only depend on the weather, how can you know the distance." ”

"Oh, yes," Xiao Ya also laughed self-deprecatingly, distance is determined by speed and time together, I don't know the speed, I can't determine the distance at all, "Oh, huh? No, it occurred to him that distance can be said in another way, that is, length, and to determine length, there is more than one way to measure distance, for example, the Pythagorean law is one of them, and all that is needed is an angle and a known length......

"That is, we don't know the distance between the islands, do we?" Xiao Ya asked.

"It's not that we don't know at all, but by comparing the direction of the island with the record pointer, we can roughly get the direction of the island, and then compare it with the navigation record, and then we can roughly guess the time required for the voyage, otherwise how to arrange the navigation plan," this is the category of navigation, so it is still Lazar who answers.

"I see," Xiao Ya nodded silently, as if he had discovered something amazing, if he could really follow his own thoughts, it would be easier to sail on the Great Channel, no, it could completely change the navigation rules of the Great Channel! Mastering that will definitely lead to untold riches......

For a while, Xiao Ya was completely immersed in his own thoughts, and even Lazar and Harus didn't pay attention to what they said later, it should be about choosing a route, as if they decided to take a long sea route, but it didn't matter, anyway, he didn't understand what the difference would be.

But when the conversation was over, Xiao Ya asked Lazar for a book on navigation, and then, to his dismay, he found that he could not read it...... Yes, although he inherited Anilu's memories and thus mastered the language and writing of this world, this does not mean that he can read all the books without barriers, because different fields and professions will have corresponding terms and descriptions, which require corresponding knowledge to interpret and understand.

And this is especially true for the nautical aspect, because really. There is no concept of navigation on the empty island where Anilu lives, otherwise this guy can't bring any pointers, so he plans to leave the empty island and go down to the blue sea, which is really scummy! Xiao Ya can only say that this is the sadness of inheriting the memory of a scumbag!

Fortunately, there is still ...... to the journey to the City of Seven Waters Oh, I don't know how long, anyway, there should be a long time, so there is some kung fu for Xiao Ya to ponder slowly, every day in addition to the routine meeting with Lazar and Harus, and accompanying Anya to relax, he spends the rest of his time studying nautical books, while constantly refining his idea.

"Huh?" Like most of the past few days, Xiao Ya, who was immersed in reading a book, suddenly raised his head, it was because a heart sound entered his sensing range, and, "At this altitude and speed, is he flying?" A moment later, after locating the other party's location through the heart net, he was surprised to find out about this situation.

In Xiao Ya's memory, the ability to fly in the One Piece world was very rare, and even his previous true . Anilu can't do it, and if you want to stay in the air, you still need to rely on Yunbei's ball cloud, so who is this heart sound? He frowned, trying to search in his mind, as if there was a birdman who had eaten a Devil Fruit in Abarastan or something, and then a few natural systems, which could be considered floating, and who else......

"Oh, and Mother? All morning? Serious general? Is it really a masterpiece? Will I come back? Xiao Ya repeated the words he had heard from his heart, trying to narrow down the search, but he still had no clue, "Who is this?" It doesn't seem like a boss-level guy, and he can call his mother. ”

However, Xiao Ya soon found that he didn't have much time to think about who this flying guy was, because the height and speed of the other party were constantly decreasing, and if it continued like this, it wouldn't be long before he would rush into the arms of the sea, so what should he do? Xiao Ya hesitated.
