Weapons: Mountains and Seas!

"Success!"

Following the craftsman's excited shout, Gray's gaze inevitably drifted over.

With a beckon of his right hand, the ring resting on the workbench flew toward him under the influence of Gray's magnetic field control.

The entire ring was only one meter in diameter.

The Flying Wheel weapon featured a hexagram design, with the ring marked at the twelve o'clock position.

At each of the twelve hourly positions, steel beads the size of an adult's thumb were embedded through the frame.

Between the steel beads, six Flying Wheels were set within the remaining six points of the hexagram. The Flying Wheels were red overall, accented with black patterns, giving them an aesthetic that made it clear at first glance that they were no ordinary weapons.

(It was roughly like Luffy's Gear Fourth; black as the base with red patterns, though the protagonist's design was the exact inverse.)

The steel beads and Flying Wheels were Gray's primary means of attack, but beyond their offensive capabilities, the design of the ring itself was a sight to behold.

Drawing on his past life's heritage as a descendant of the dragon, Gray had carved two intertwined five-clawed golden dragons on the left and right sides of the ring.

Naturally, to match the two golden dragons, the entire ring was forged from solid gold, ensuring not only its beauty but also the mystery and power of the "two dragons playing with a pearl."

This was the ultimate weapon Gray had designed for himself: Mountains and Seas!

Excluding labor costs, the materials alone for the weapon had cost two hundred million Beli.

Controlling the magnetic field, Gray positioned Mountains and Seas behind his back, hovering at a distance of five centimeters.

"Looking sharp, young master Gray!" The many craftsmen all gave him a thumbs-up, sighing in genuine admiration.

Someone brought over a full-length mirror, allowing Gray to clearly see his own image.

At fourteen years old and nearly two meters tall, Gray's handsome face, paired with the mysterious and ornate Mountains and Seas, exuded an aura of a powerhouse.

If he were to fly into the sky, barefoot, the sheer suffocating intensity of it—Gray felt it was formidable just thinking about it.

"Zehahaha! I am very satisfied!"

"Of course, with the combined efforts of all our craftsmen, plus you melting the ore for us, it would have been impossible for us to forge a subpar weapon."

"I can guarantee that your Mountains and Seas, even if it doesn't reach the level of a Supreme Grade Sword, will be more than enough to qualify as a Skillful Grade Sword." Having poured their hearts and souls into the weapon, all the craftsmen had utilized their full expertise, so naturally, they wouldn't let the weapon turn out poorly.

"Hahaha! Excellent!"

"Rest assured! I will not only make this weapon famous, but I will also forge it to the level of a Black Blade."

"Once I have made a greater name for myself in the world, this—this will be a Supreme Grade Sword!"

Hearing this, the craftsmen were overjoyed. Even if they knew it was a pipe dream, being able to participate in the forging of such a weapon in their lifetime left them with no regrets.

Moreover, as people who had dealt with ore their entire lives, they knew that someone capable of melting ore through sheer ability alone—like Gray—would not be weak.

Even if Gray couldn't become a top-tier powerhouse, simply being a famous one would ensure this weapon was never buried.

"Haha! We believe in you, young master Gray."

"We'll talk about fame later; just wait and see." Having obtained his new weapon, Gray couldn't wait to test it out. "I have seen all of your hard work. Everyone will receive a six-month bonus; go add a gift for your families!"

"Now, I am going out to test the weapon!"

"Then thank you, young master!" Watching Gray fly directly away, the craftsmen, having already received their benefits, were naturally not stingy with their gratitude.

Whoosh!

Moving at lightning speed, Gray reached the high altitude. Looking down at the ground, an indescribable sense of exhilaration welled up in his chest, making him want to let out a loud roar.

Unfortunately, this was the family's secret weapon manufacturing base, and such behavior was ill-advised, forcing Gray to suppress the impulse.

Standing in the sky, his Observation Haki enveloped the world, and Gray viewed himself from a god's-eye perspective.

On the golden ring of Mountains and Seas behind him, the carved dragons playing with a pearl shimmered under the sunlight, lending Gray a touch of majesty.

Inside the inner circle of Mountains and Seas were six golden frames, within which the Flying Wheels were spinning.

These six frames had a purpose: when Gray wasn't using his ability, the frames remained magnetic, adhering to the Flying Wheels so they wouldn't fall out.

Once Gray activated his ability, the magnetic field became a unified whole, and the hollowed-out Flying Wheels inside would naturally rotate, spinning like little windmills.

Although the color and size of these Flying Wheels had changed, they still inherited the aesthetic of the snowflake pattern.

The fiery red snowflakes, accented with black patterns, gave the Flying Wheels a mysterious, alluring aura even without being snow-white.

The Flying Wheels were only ten centimeters in diameter, roughly the size of an adult's palms pressed together.

Of course, one shouldn't underestimate them just because they were small.

The primary material this time was mostly ore from the bottom of a volcano, which Gray had melted and purified to its absolute limit before combining it with two other materials to reach its final form.

The weight of a single wheel reached fifty kilograms, and the limit of the high temperatures it could withstand had been greatly expanded.

As for the specific numbers, Gray couldn't test them right now; he could only estimate based on the craftsmen's experience: likely between three thousand and five thousand degrees Celsius.

Though that might not seem like much, if coated with Armament Haki, the temperature the Flying Wheels could withstand would increase significantly.

If he could train it to the level of a Black Blade, even if Charlotte Oven were to come, he might not be able to do anything about it, no matter how hard he tried.

Gray controlled the magnetic field to keep Mountains and Seas behind him. Once the magnetic field was set in motion, he didn't need to waste any mental energy; he could control it instinctively, like breathing, allowing Mountains and Seas to follow him automatically.

Whether he was attacking or flying, it would not interfere with any of Gray's other actions.

Of course, if you say it's hard to get through the door, then pretend I never said anything.

"Then~ let the test officially begin!" Standing in mid-air, Gray held his left hand behind his back and flicked his right hand forward in a sword-finger gesture. A Flying Wheel automatically detached from the Mountains and Seas behind him, its rotation speed increasing rapidly under Gray's control.

At the same time, Gray drew the Armament Haki from within his body and imbued it into the Flying Wheel.

The originally red and black Flying Wheel was instantly covered in black, yet the red light seeping through the darkness made the entire wheel look like a volcano on the verge of eruption.

"Magnetic Field Rotation: Five Thousand Horsepower!"

Gray went all out right from the start.

Dense electric light masked the color of the Armament Haki, and the entire Flying Wheel flashed like a bolt of lightning, shooting out instantly.

Hum, hum.

The high-speed rotation of the Flying Wheel and its rapid flight caused the very air to vibrate.

Swish~

After the first Flying Wheel struck, the second and third followed in succession.

Under Gray's control, the three Flying Wheels streaked rapidly through the air within a hundred-meter radius around him.
