People are pirates, this navy is not very fair!

Hulk Island.

Tom, Espagu, Franky, and a big frog, Yokozuna, stood in front of a steam locomotive.

It took them three days to assemble it.

Franky was so excited that he hugged the frog Yokozuna, and he shouted happily:

"Mr Tom!

Great, we have assembled the locomotive.

Next, just let it run on the top of the sea track, and we have succeeded! "

"Hahaha! It's still early! Let's try it out first!"

Tom laughed and put his arms around the locomotive.

In order to test whether the train could run on the sea, the three had already built a short track near the coast of Hulk Island.

Under the terrifying power of the murloc, the steam locomotive weighing hundreds of tons was easily lifted up and placed on the starting point of the track.

Before Tom could give an order, Frankie volunteered with his golden eyes shining:

"Mr. Tom, let me drive this train!"

"Hahaha! It seems that you can't wait any longer, so it's up to you to start the train!"

Franky laughed, and quickly ran into the power room at the front of the car, began to add coal to it, and started a fire.

A moment later, steaming black smoke came out from the steam locomotive, and with the roar of "Boom, boom!", the locomotive slowly drove out, and the speed of the metal wheels was getting faster and faster.

however……

As soon as the front of the steam locomotive drove less than twenty meters away, the entire front of the locomotive fell uncontrollably into the sea. Franky was so frightened that he quickly abandoned the car and jumped into the sea, thus escaping the fate of being buried under the sea.

Seeing this, Tom jumped into the sea with a "Plop!", splashing a big pool of water.

He wasn't going to rescue Franky, he was very aware of the latter's water quality, as long as he didn't throw him into the huge vortex of the ocean current, he would basically be able to swim back alive and kicking.

What he was going to save was the steam locomotive!

If he scrapped a steam engine every time he failed, his wallet wouldn't be able to bear the waste!

The murlocs are the darlings of the sea. Compared to on land, they can fully display their racial talents in the sea.

Soon, Tom went down from the bottom of the sea, carried the head of the steam locomotive on his shoulders, and climbed onto the shore.

Frankie, who just swam to the shore from the sea, shook his wet blue hair, and said with a speechless expression:

"Mr. Tom, isn't the locomotive you built said it can sail on the sea?

Why did you fall into the sea..."

Hearing this, Tom suddenly laughed and scratched his head.

"Ahahaha! This is also impossible...

This situation will happen, in addition to the lack of buoyancy of the suspension device of the track and the car body, and the speed of the sea train is not fast enough...

I am also very distressed!

If the efficiency of the steam engine can be increased from [-]% to more than [-]%, it should be able to enter a state of equilibrium, right? "

"What if another mechanical device is used to provide power, and the energy efficiency can reach more than [-]%, or even [-]%?"

Hearing this somewhat familiar voice, Tom turned his head in surprise and looked at Sephiroth, who was walking slowly from a distance.

"If that's the case... then it's really loud!

Maybe, the sea train will be able to drive directly on the sea, hahahaha! "

"Oh!? Then I think you should be very interested in this thing."

Sephiroth opened a design drawing in his hand in front of Tom.

"Can you tell me how it works?"

Tom, the shipbuilder, looked at the mechanical schematic diagram and the rough cross-section of the internal combustion engine in the boy's hand, and he couldn't help but fell into deep thought.

He dared to boast in front of the judge, saying that a sea train connecting multiple islands could be built within ten years.

That's because his own mechanical engineering attainments are very good, and he knows that as long as he breaks through certain technical difficulties, he can turn the sea train into reality.

Therefore, Tom the shipbuilder understood many things in an instant when he saw this internal combustion engine drawing.

"This is a heat engine that uses diesel as fuel and can convert heat energy into power..."

Sephiroth told the world's number one shipbuilder of One Piece the internal combustion engine knowledge he had learned in high school in as much detail as possible, hoping that the other party could understand the existence of this machine as soon as possible.

Franky forced himself over. After listening to Sephiroth's explanation, an excited smile immediately appeared on his face:

"Mr. Tom, this thing is so interesting! I think I can try it!"

"Hahahaha! It's really loud!

Brother, you are willing to tell me the principle of this machine, you are really a resounding man! "

Franky can understand it, and Tom, as his teacher, naturally has no problem understanding it.

"Brother, can you show me the relevant part size drawings."

Hearing this, Sephiroth shook his head decisively, and casually said:

"I don't have that kind of thing at all. This is all I figured out on the spur of the moment."

As a surgeon, if someone asks Sephiroth to talk about medicine, he can talk about it in detail and make sense.

but……

mechanical engineering?

If he can draw a rough schematic diagram of an internal combustion engine, it would be great if he could draw a rough schematic diagram of an internal combustion engine. Asking him for parts dimensional drawings or something like that is really difficult!

"Oh! That's it! That little brother, you are also very powerful...

By the way, what's the name of this machine? said Tom with a laugh.

"internal combustion engine."

…………

After chatting with Tom about the internal combustion engine, Sephiroth took the swordfish and headed home.

Professional things are left to professional people.

In the case of the sea train project, that's all he can do.

Of course, he is not without extra gains, at least he has won the favors of Tom, Franky, and Asbagu.

If he wants to ask the three of them in the future, with their personalities, as long as it is not too troublesome, the other party should help...

When Sephiroth returned home, a guest had already arrived in the living room of his house, and the three Boya sisters were sitting on the sofa next to them, waiting for his return with each other.

The guest was Hughes Silk, the president of the Hughes Shipbuilding Company. He was a red-haired middle-aged man with a burly figure and a tough face in a black suit.

"Sephiroth, it's really you...it's great that you're fine!

I heard that your passenger ship was attacked by pirates...

By the way, where's your father Parr? " Hughes Silk said excitedly.

"He was killed by pirates to protect me..."

As he spoke, Sephiroth sighed lightly, his eyes a little sad.

The man named Carl D. Parr was a great father who could sacrifice his life for his son.

Karl D. Sephiroth's mother died of illness not long after he was born, and only his father raised him.

Therefore, in Yuan Bo's heart, his father is the most important existence in his heart...

Hearing this, Hughes Silk also sighed lightly. He looked at Sephiroth and said solemnly:

"How about it!... Sephiroth, how about you come to work in the shipbuilding company from now on?

Although the company is in a downturn right now, you come to work in the company and you have a stable income..."

"No, thank you for your kindness! Uncle Silk, to be honest, I am going to join the navy..."

Hearing this, the three Boya sisters next to them suddenly spoke in unison and shouted in surprise:

"Navy!!!" x3

"Sephiroth, why do you want to be in the navy?" Boya Hancock frowned slightly, his tone full of doubts.

"Because...! Not only do I need strength, but I also need to have the power to rival the Hundred Beasts Pirates in order to take revenge...

Joining the navy is my best choice at the moment. "

Sephiroth's eyelids were lowered, and there was no emotion or anger on his face, but his tone sounded very firm.

The navy of the One Piece world is established by the world government to serve the world government members and world nobles.

The navy has no right to interfere in the internal affairs of other countries, and even less has the right to disobey the orders issued by the world government. Their duties are only to maintain the law and order of the sea, fight against pirate forces, and help the world government do some dirty work, and sometimes even kill people. They also help set the fire...

However, even though the navy has various constraints and disadvantages, it is undeniable that the navy already has a fairly mature system for cultivating talents.

Anyway, after this period of training, Sephiroth can be regarded as able to see that he has the overlord-like arrogance and the phantom beast-like vampire fruit, but he does not have a systematic way to become stronger, and he cannot exert these things to their maximum effect .

As a result, even if he spends ten hours a day exercising, he only feels that his physical fitness has improved slightly. In terms of combat experience, he is still almost equivalent to a blank sheet of paper...

In this world, there has never been a shortage of top powerhouses who grew up from constant fighting, Roger, Kaido, Charlotte Lingling, Edward Newgate...

but……

Compared with Ye Luzi becoming a monk, Sephiroth, who had received a systematic education in his previous life, still believes in the training of a professional class system, and the navy is a more reliable existence.

"Is that so? Both strength and influence are necessary..."

Boya Hancock murmured thoughtfully.

Seeing this scene, Hughes Silk stood up from the sofa, patted Sephiroth's shoulder lightly, and sighed:

"Hey! Sephiroth, since you have already made a decision, I won't persuade you anymore.

If you need my help in the future, you can come to me..."
