The ghost sword hero of the pirate

“I’ve finally waited for this day, and I can’t wait any longer!”

On the beach on the main island of Twin Islands, Dan was in a happy mood, looking at the work he had participated in in front of him.

Today is the day for the airship test flight. The results of the two months of hard work will be tested, and there will be a result whether it is successful or not.

"Inflate it!"

Tesla was so confident in his design that when everyone was present, he issued the order.

呲——

As Dan pressed the switch, a large amount of gas began to be ejected from the two pipes connecting the pod to the airbag. The shriveled pufferfish skin that originally needed to be hoisted by a rope slowly bulged up.

"Captain, this one is much more domineering than the previous Pufferfish."

Parnell stood next to Ferro and praised him without hesitation.

Although Parnell had seen the spiny pufferfish caught by Dan that day, it was not an exaggeration to say that the pufferfish was already dead at that time and the bone spurs all over its body had shrunk.

But now, after the skin of the spiny puffer fish is filled with gas, the bone spurs gradually expand, making it look more and more ferocious.

"Haha, since it's an upgrade, of course we have to use the best materials. I just don't know what Morgans' expression will be when he sees it."

Ferro chuckled and was quite satisfied with this time.

A few minutes later, the airbag was fully inflated, and everyone was already under the huge shadow, looking up at the full view of the airship.

The pod under the air bag is also suspended steadily off the ground. If it were not tied to a cable, it would have taken off long ago.

I saw that two streamlined metal shells have been installed on both sides of the pufferfish's pectoral fins, and there is a propeller at the tail of the shell.

Two metal wires are led out of the shell, close to the pufferfish's skin, and extend to the top of the pod below.

The Pufferfish's eyes are replaced by two large light bulbs, so that the Pufferfish can see clearly what's ahead at night.

"Tesla, it uses your ability as its power source, right?"

This airboat is twice the size of the original Fugu, and the ordinary power system simply cannot drive such a large volume, so Ferro made this guess.

"Yes, at the beginning of the design, I considered using the power of lightning. The advantage of this is that it can save a lot of fuel and does not need to come down every once in a while to replenish it.

Also, by abandoning the steam engine, there can be one-third more space inside the pod, and there is no need to worry about fresh water."

The previous Pufferfish had never been able to satisfy Tesla due to various restrictions, so after obtaining the Thunder Fruit, Tesla, who had no restrictions, finally unleashed his creativity. When he heard Ferro's inquiry, he was proud of it.

explained.

"Hey? Tesla, if something happens to you and you can't get away, wouldn't this airship become a decoration?" Walton asked.

After hearing Walton's words, everyone fell silent and looked at him in surprise. If these words came from other people, everyone would not be like this. However, they did not expect that it was Walton, a guy who doesn't like to think, who first proposed it. Everyone really

I didn't expect it.

"Hey! What are you looking at? Are you looking down on Mr. Walton? I'm just too lazy to think about it. I'm not an idiot, okay?"

Walton realized the deep meaning in everyone's eyes and stopped immediately.

It was Tesla's kindness that diverted everyone's attention and said, "Don't worry, I've thought of this a long time ago. Look at the pufferfish's bone spurs."

Everyone looked in the direction Tesla was pointing and discovered what was hidden. There was a long metal needle inserted into the bone spur, all the way into the airbag.

If you look carefully, the bone spurs inserted into the metal needles are concentrated on the back of the puffer fish, very regularly.

"This is my latest invention, which uses the conductivity of metal to collect high-altitude lightning into the air bag.

Inside the airbag, there is an electrical storage device made of metal sheets. If the battery is fully charged, the vehicle can drive continuously for more than five days.

Of course, if it’s safe, don’t worry, the pod has been installed with a lightning protection device.” Tesla jumped on the back of the pufferfish, pulled out a metal needle, and taught everyone about it.

"Five days is enough. Considering the weather in the New World and the Grand Line, the chance of no thunder and lightning in five days is very small."

After saying something with satisfaction, and seeing that everyone was eager to give it a try, Ferro gave the order directly.

"Boys, let's set sail!"

"oh......!"

...

After half a day of testing, the airboat returned to the sky above the Twin Islands.

Everyone responded with great enthusiasm to the fully upgraded airboat, taking turns to experience the pleasure of controlling it.

And Tesla did not disappoint everyone. All aspects of the airship's performance were unanimously recognized by the pirate group.

"By the way, Captain, is this airboat still called the Pufferfish?"

The last person to experience it was Parnell. He controlled the airship to slowly descend and asked.

Hearing Parnell's inquiry, Ferro was startled and realized that the airship had not yet been named.

After thinking for a while, Ferro didn't have any good ideas, so he began to solicit opinions from the crew.

"Let's see, let's call it Fatty. It goes well with the pufferfish's round body shape."

Walton was the first to propose, and after speaking, he winked at Parnell proudly.

"Keep this name to yourself."

Rolling his eyes at Walton, Parnell expressed his thoughts, "I think it's better to call it the Big Blowfish. The positive name echoes the previous Blowfish."

This name is more reliable. After hearing Parnell's proposal, everyone expressed their approval.

"What about you? Tesla, this is your masterpiece, what do you think?" Ferro looked at Tesla.

"Actually, I thought of a name at the beginning of the design, and it's right here." Tesla took out the drawing and handed it to Ferro.

Everyone also gathered around curiously, and the first thing they saw was a line of big characters - Feitian Netherworld.

"Okay! Just use this name!" everyone said in unison.

...

Two days later, after preparing enough food and fresh water, the Feitian Netherworld left the Twin Islands at noon.

The purpose is to go to Del Salado to mine the seastones. The paddle steamer has been built for several months, but the only problem is that the seastones on the bottom of the ship have not been installed.

Therefore, on the third day of the Feitian Nether's test flight, Dan and Parnell led a team to mine.

"Okay, it's time for us to go back. The progress over at Salles is almost complete."

With that said, Ferro used his ability to make his soul vibrate at a special frequency.

This is the only special way of contact between him and Toral. As long as Toral is not too far away, he can sense Ferro's call.

A few minutes later, with a roar, Toral returned to Ferro.

"Let's go, Walton."

Leading Walton to jump onto Toral's broad back, Ferro looked at Tesla worriedly, "Be careful yourself, Tesla."

"Don't worry, Captain. Even if I encounter a strong enemy, I can escape without any problem."

"Okay, let's go Toral!"
