The real core technology of sea trains is actually not a steam engine, but its track.

Although the technology level in the East China Sea is generally relatively backward, William can know from some limited news that in many places in other seas, even electricity has begun to become popular. The technology level of the navy and the world government will only be higher than the average level in the East China Sea and cannot be more backward. Judging from the news from Ajin, who is on a great route, the steam engine is not a great technology for the navy and the world government.

The real amazing technology of sea trains is that they can make special sounds during driving, so that the tracks laid on the sea will not be harassed by sea kings, so that they are safe and worry-free.

In fact, the long tracks on the sea trains should be more susceptible to attacks by sea kings due to their spans. Once damaged by attacks, the possibility of cars being destroyed and people being killed may be greater than that of ordinary ships.

But in the years when sea trains were in operation, no one had ever attacked the track, which shows how practical the technology that Tom invented in the fishman was.

This sound wave technology that relies on trains and tracks to collide with marine life, in this marine world where dangerous creatures are everywhere, is no less effective than a steam engine.

And it is not like a steam engine, it is a unique technology for offshore trains, and there are no similar applications in other places.

William, who noticed this at the beginning, sometimes even suspected that it was this technology that caused the invention of maritime trains for so many years, and the world government still had no intention of promoting them.

The world government itself has the technology to cross the windless belt and travel smoothly in various sea areas. According to Ajin, the navy has a special warship that can be protected from attacks by sea kings after the sea tower stones are inlaid on the bottom of the ship, so as to drive safely in the windless belt.

But Hailou Stone is an extremely precious and rare mineral. Except for the world government, few forces can learn from them to do so, and the luxury of wasting Hailou Stone.

Monopolying this kind of traffic technology makes the connection between the four seas and the great route easier to control. The four seas pirates lead to the great route basically can only go upside down and prevent the already chaotic and difficult to control the great route, which is more difficult to control because of the disorderly influx of the four seas pirates.

William will definitely go to the great route, because this is the center of the world and the focus of the world's attention. There are the most demon fruits and the most outstanding talents here, and the highest stage for the great pirate era to compete for the world. How could William miss it?

However, the windless belt is an isolation belt that blocks the passage between the East China Sea and the Great Route. Although it can pass through the Overturned Mountain from the East China Sea, after entering, it becomes inconvenient to return, and the connection between each other will become difficult.

William has worked hard in the East China Sea for many years and could not leave his foundation here and go to the great route alone. In that case, what is the significance of what he does in the East China Sea?

So from a long time ago, he had been planning for this to maintain control over the East China Sea while entering the great route, preventing the windless belt from becoming an obstacle to traffic connection, and turning the East China Sea into its own back garden.

William could not learn from the world government and the navy, so he made so many sea tower stones for his ships to use, so he eventually abandoned the wind, used steam as the driving force, and used sound waves to drive out the Neptune ships, which was included in the plan.

Therefore, the sea train became William's vehicle that he never forgets because it had the key technologies he needed.

The design drawings that Bucky took a look at it at first sight and was amazed by it were actually this special ship. Bucky quickly realized that this kind of ship could only solve the two major problems of passing through windless belts, and how practical it is.

And Esbagu quickly understood.

Before this, perhaps because of the blind spots in thinking, the masters and apprentices of Tom Studio have always thought about how to build sea trains, including steam engines and train track technology, invented and constructed for the smooth sailing of sea trains. The original designers, Tom, Carter Flam and Espagu, had never thought about the technology of using the collision of train tracks to generate sound waves to drive out sea kings on other ships.

Esbagu didn't expect that someone would have been able to make ideas that even designers could not even associate with the East China Sea, thousands of miles away, without seeing the sea train with his own eyes.

However, this idea is not without the possibility of operation. Esbagu is actually a little eager to try it out. As an excellent shipbuilder, he also wants to build a ship that can conquer the windless belt that makes people feel terrified.

...

When the group arrived at Tom's studio, Clow and Esbagu discussed a bunch of trivial matters such as their daily living and living places, Edmund and Akin quietly stayed away from here and avoided the crowd.

After reaching the corner where there are no outsiders, Edmund took out a few notes and a fruit from his bulging arms and gave it to Ajin: "What William asked me to give to you is his personal experience of the Six Styles and the return of life, as well as the practice of fishman karate he has recently obtained. As for this fruit..."

"Devil Fruit!?" Ajin said in surprise.

William paid for this devil fruit almost as much as the reward he paid for the steam engine.

But even with William's power and financial resources in the East China Sea, he was unable to loot more devil fruits in the East China Sea. So far, except for the growing furry fruit in the Square of Destiny, William only has this one in his hand, and he entrusted it to the trustworthy Edmund and handed it to Ajin for food.

When William and Edmund talked about the candidates for the expedition team, they mentioned giving Ajin something. This thing mainly refers to the devil fruit.

"William thinks that you may need this to enhance your strength at the Navy headquarters," Edmund said. "But he doesn't know what kind of fruit this is. If you have concerns and worry that your ability will affect your strength, you can choose not to eat it. William said, if you don't eat it, just let me eat it, but..."

"...I see this fruit is so weird, it seems to be poisonous," Edmund said jokingly, "You'd better eat it."

Upon hearing this, Ajin did not refuse, and directly took the devil fruit and bit it down.

The bitter taste and strange taste made Ajin grin, and he said vaguely: "If I eat the devil fruit that should have enhanced the ability of the eater, it means that I cannot adapt to this era and should be abandoned by this era because there is no useless ability, only useless users."
