"Moonstep? I can fly, and my elemental body is as light as a feather. Learning Moonstep will allow me to move at high speeds in the air, which is like adding wings to a tiger. However, I still need to defeat a marine who can do it."

Next, let's look at the blueprint of the weather modification machine core we just collected:

"Weather Modification Machine Core: A lost technology from the small sky island nation of Visalia. This core of the Weather Modification Machine could arbitrarily modify the weather in a small area. Later, the core was damaged and the blueprints were lost. The name "Weather Country" was no longer worthy of its name, and only a few simple weather manipulations could be achieved manually."

"Isn't this the place where Nami was blown away in the original novel?" Nami studied there for two years, and Jiang Bo only saw a glimpse of the plot. Jiang Bo was shocked. He didn't expect that this was because the core of the weather machine was lost.

"I'll go there when I have the chance and see if we can become friends. I'll also exchange the manufacturing drawings of the meteorological machine for them." It's useless to have the core drawings without the meteorological machine drawings, so Jiang Bo decided to go and take a look when he had the chance.

"Is the thunderstorm on this island caused by the scientist Hercules?"

There was nothing more to gain afterwards. Those technical personnel also handed over their technical information. Jiang Bo and others could not understand it, so they just packed it up and took it away. In addition to these, there were also firearms, which Jiang Bo planned to take out and sell for a good price.

On the way, Jiang Bo found Hercules' laboratory and saw the so-called weather control instrument, which looked like a huge round iron ball with an operating room in the middle. After hearing from the technical staff that this instrument could only change the weather conditions of cloudless, thundercloud and raincloud, Jiang Bo thought to himself that it was rubbish.

Hercules looks impressive, but his technological prowess is just so-so. Giving you a technical core and you're able to create three types of weather patterns—isn't that rubbish? Jiang is talking without any hesitation.

Asking the technical personnel to shut down the thunderstorm weather on Thunder Island can be considered a goodwill gesture to the residents of the island.

"Bulu bulu bulu, bulu bulu bulu." Jiang Bo had just turned off the weather instrument when he heard the sound of bulu bulu. A snail with its eyes wide open was calling nearby.

"Could this be the Den Den Mushi?" To be honest, this was the first time Jiang Bo saw this thing, one of the biggest black technologies in the world of One Piece.

"Sir, this should be a call from headquarters, asking about the progress of Lei Metallurgy. Do you want to connect?" The technical staff member next to him explained patiently.

"Answer it, why not?"

"Moshimoshi, Hercules, why did you take so long to answer my call?" A neutral male voice came from the Den Den Mushi, and the Den Den Mushi also turned into a square male face.

"Although I don't know how to address you, let me introduce myself first. I'm the captain of the Fallen Angel Pirates. My name is Jiang Bo, and I chose my nickname myself. You can call me Lucifer Jiang Bo." Jiang Bo's joking voice came from the microphone of the Den Den Mushi.

The man on the other side of the Den Den Mushi's face changed. "Fallen Angel Pirates? You're so brave! Do you know the consequences of provoking Germa 66?" the man on the other side threatened.

"I really don't know, but I do know that I seem to have found a little thing called Thunder Metal here, which seems to be very useful to you guys?" Jiang Bo replied calmly. "Am I afraid of you? If you have the guts, just jump over from the Den Den Mushi and hit me!"

"How much do you want?" the person on the other end of the Den Den Mushi pondered for a moment and asked.

"You are so cold-blooded. Haven't you asked about the situation of your subordinates yet? I don't want to talk to you. I don't want money. As long as you are unhappy, I will be happy. Goodbye!" Jiang Bo did not play by the rules and hung up the phone directly.

This thunder metal seems to be something very important to Germa 66. It's even more of a treasure. Exchange it for money? Dream on!

If you wait another two years, you will be wiped out by all members of the navy. I have no interest in dealing with you. I just introduced myself. It would be great if you could help us promote our business. It's a no-cost business. I can make money from Lei Metallurgy and save some publicity fees. Perfect!

There wasn't much to do after that. By evening, the laborers had finished refining the Thunder Iron, and Jiang Bo, keeping his promise, let them go. From there, it was the researchers' turn.

For two consecutive days, Jiang Bo practiced the transformation of small-scale thunderclouds and achieved some results. The researchers' thunder metallurgy forging was also nearing completion.

Just when Jiang Bo and his friends went to the laboratory to watch the Lei metal being produced, a small accident happened.
