The ghost sword hero of the pirate

Windless Zone, Twin Islands.

At this time, a large amount of sand and gravel had been cleared out of the trench between the two islands, and the bottom was no longer visible at a glance.

As the trench deepened, it became a good dock, and the first ship to dock here was the Netherworld.

"Oh, it's so boring! If I had known better, I would have stayed in Dressrosa."

Walton leaned on the mast and complained listlessly.

He has been staying on this desert island for a month, leading the crew to continuously build the island every day. Compared to the atmosphere of the arena, this place is simply not a place for people to live.

"I don't know who said it. The captain must take him with him next time he goes to sea. Now that he is taking you, why are you blaming others?"

Parnell was in a very good mood. He was holding a fishing rod and sitting on the bow of the boat, catching fish leisurely.

Suddenly there was a strong force coming from the fishing rod. Parnell shouted "I'm hooked" and pulled up the fishing rod with all his strength.

However, the fishing rod was stretched to the limit and the fishing line submerged in the sea still did not move upward at all.

"Hey! You lazy guy, come here and help me, I have a feeling it's going to be a big guy!"

In desperation, Parnell shouted to Walton.

"I've told you a long time ago that this is a windless zone, so don't fish randomly. Now even the sea kings have taken the bait."

Although he complained, Walton still got up and went to the bow of the boat. He grabbed the fishing rod and worked hard with Parnell.

Snapped!

With the combined strength of the two of them, they could even lift the boat. Naturally, the slender fishing rod couldn't withstand such a pull and broke off in an instant.

"Hey! You idiot, do you know how to fish? Now it's better, even the fishing line is broken."

Throwing the fishing rod down, Parnell said angrily that he now regretted asking Walton to help.

Wow——

Before Walton could refute, huge waves suddenly appeared on the sea surface, and a giant pufferfish full of bone spurs emerged from the sea.

Then a figure followed closely, crossing out of the sea and landing steadily on the deck of the Netherworld.

"Did you help me just now? Thank you very much."

The man spoke slowly, it was Dan who had left the Twin Islands for a few days.

"Of course, we figured that you would be coming back, so we specially gave you a hand."

Parnell and Walton looked at each other and said at the same time that although they always made trouble for each other, Dan could not let Dan know about the embarrassing incident just now.

"Okay, you clean the internal organs of the spiny pufferfish as soon as possible, and then drag it to the shore to tan it."

After chatting for a few more words, Dan turned back and said to the fish people who were still in the sea.

The fishmen were very experienced in dealing with such large puffer fish and immediately started cleaning them up on the shore.

"It seems that our Pufferfish is about to be upgraded. You really caught a big guy!"

Parnell was very clear about Dan's purpose of going out this time, which was to look for bigger river dolphins.

The previous Blowfish had been delivered to Morgans a month ago, which was what Ferro had promised.

In fact, after the Blowfish was built, Morgans approached Ferro for it. However, the pirate group needed to go to Sky Island at that time, so Ferro postponed the delivery on the pretext that the Blowfish still needed testing.

On the third day after Ferro returned to Dressrosa, Morgans visited the island with the purpose of taking over the Fugu.

At that time, Morgans' pained expression when he showed Pele, Parnell still remembers clearly now, he paid double the price and advertised for free in the arena to get the Blowfish number.

Therefore, after Dan came to the Twin Islands, he began to look for a more suitable sea dolphin, because Tesla wanted to build a fantastic airboat this time!

"Haha, we were very lucky this time. We actually found the rare spiny puffer fish. In order not to damage its skin, we spent a lot of effort to catch it."

Dan chuckled, with a nonchalant expression on his face, but the dangers involved can only be understood through personal experience.

It wasn't that Dan wanted to take risks in the windless zone, it was just that such a large river dolphin could only be found in the windless zone, so he had no choice but to do so.

"By the way, I heard that your eldest brother Tom is a pufferfish mermaid, right? Don't you feel strange that you attack pufferfish?"

Walton asked weakly.

Bang!

What answered him was the thick and powerful tail fin of the wolffish.

"Ah, Dan, I was wrong, please save me! I can't swim!"

"You deserve it! I'll make you mouth-watered!"

...

At this time, inside the main island of Twin Islands, there was a laboratory that had just been built.

Although various facilities are not yet complete, simple experiments can already be carried out.

Sizzling——

A piece of whitish metal that had been heated out of thin air was dropped into the cooling water by Tesla.

"It should work this time. If it doesn't work again, we have to think of other options."

Tesla, who has failed dozens of times and has mastered a large amount of experimental data, said with confidence.

"I hope so."

Ferro knew nothing about materials science, so he had no choice but to let Tesla do his thing.

After a few minutes, seeing that the metal had cooled, Tesla clamped it out and placed the prepared sea-floor stone on a solid stone platform.

Click!

Tesla picked up the metal block, pointed the sharp side at the sea floor stone, and pushed it hard.

Visible to the naked eye, the sea floor stone was suddenly chipped away by the metal. The experiment was a success!

"Well done Tesla."

Picking up the piece of metal, Ferro asked, "How about using this metal to make weapons?"

Seeing the hardness of metal, Ferro first thought of making swords. In the past month or so, the pirate group has recruited hundreds of pirates, and these people are in urgent need of weapons.

If they can all be equipped with such sophisticated weapons, then the strength of the pirate group will be greatly improved, and they will be able to better cope with future wars.

"I'm afraid this won't work, although after refining, the hardness of the metal has exceeded that of sea floor stone.

But its toughness is so poor that it cannot withstand several impacts, and now it can only be used for mining sea floor stone."

Tesla naturally knew very well what he had developed, and immediately gave up Ferro's illusions.

"Okay, let's leave it at that for now. The mining of Hailou Stone is still the main focus at the moment. Don't worry about other things."

Tesla's analysis was very clear, and Ferro no longer struggled. With Tesla, his fantasy would one day come true.

As for using this metal to make bullets, Tesla and Ferro both thought of it, but neither proposed it.

Because, based on the cost of this metal, if it were made into bullets, even the wealth of the Netherworld Pirates would not be able to afford it. In that case, instead of shooting bullets out, they would shoot out shells one by one.

profit!

"Captain! I have caught a suitable pufferfish and can make the airbag in a few days." Dan walked into the laboratory.

"Oh, great! Now I can take the next step!"
