One Piece: The Max-Level Blacksmith of Marineford

Tina: ......

The only thought in their minds was, why could a knife make the sound of a hammer striking iron?

Looking at the wood again, it wasn't split in the middle; instead, it looked as if it had been hammered. The entire piece of wood was deformed, and the cracks were very clear.

"Why is a knife that can't chop but instead becomes a hammer???"

The scene before her eyes completely shattered Tina's worldview.

Even Iron Hammer, who knew the cause and effect, was speechless for a moment.

"Tina, I've realized that your abilities aren't suited for knives, swords, or guns; blunt weapons are more suitable for you."

"Look, this knife is such a great hammer, with a unique design and amazing effect."

"Hmm... I need to take this to that old man from the Warring States period; maybe I can burn his CPU dry."

Suddenly, a thought struck him. He decided to go back and tease the old man from the Warring States period to get revenge for what he had done before.

But just to be on the safe side, Iron Hammer decided to give it another try.

"Tina, get a few more hammers, I'll give it another try."

"it is good!"

Tina then obtained several more long black hammers, which she then forged into battle blades.

The result was the same: a sword model, but the capabilities of a hammer.

The blade fell with no smoothness, only immense force.

For a moment, the hammer was in a bit of a headache. Although the increased strength and hardness were good, it had lost its sharpness.

Sigh, it seems like from now on we'll only be able to make hammers using the Cage-Cage Fruit.

Even a flail wouldn't work, because without its sharpness, a flail that relies on spikes for damage would lose its power.

But Iron Hammer suddenly had a great idea for the new ability, and casually took out a box containing magma, a hint of anticipation flashing in his eyes.

I'm begging you all to give this a like, write a short review, and if possible, give it a five-star rating.

Chapter 131 Special Tempering Ritual

Magma is a peculiar substance with unique physical properties; it is both a hard solid and a soft liquid. Like red-hot glass, it can flow and bend, yet it is also extremely hard and dense.

Black Gun is a product of the Paramecia-type Cage-Cage Fruit.

Magma is a product of the natural type, Magmaberry.

If black guns can be forged, then there's no reason why magma can't be.

Previously, Iron Hammer didn't forge magma because he had no idea where to start, but since he mastered the Devil Fruit's ability to shape things, he has had a new idea.

"Wow, it's so hot, what's this?"

Once the magma is extracted, its extremely high temperature begins to dissipate.

The box he used had steel plates with seastone properties embedded inside, which was the only way to contain the magma; otherwise, an ordinary box would have been burned through long ago.

But then Hammer was a little confused. This thing was extremely hot. If he put it on the anvil, it would probably destroy the anvil.

How do you forge this?

Suddenly, a thought flashed through Iron Hammer's mind: if lava can't touch anything, then why not just prevent it from touching anything?

However, his abilities would cause a huge upheaval, so the arsenal is no good. If the arsenal is destroyed, tsk tsk tsk, the old man from the Warring States period will definitely swindle him out of his money.

"Tina, wait for me here, I'll be right back."

With a single shave, Iron Hammer vanished from his spot, dashing out of the armory and using Moonwalk to arrive at the back of Marineford Castle.

He found an open space and got ready to get to work.

He smiled slightly as he dragged the lava box.

"Let's do it!"

"Hammering shapes! Anvil!"

Holding the box in his left hand, he began to use his abilities with his right.

The terrifying hammer blows began to emanate, and Duang! Duang! They quickly coalesced into the shape of an anvil.

Then the hammer poured out the lava.

As soon as the magma, in a semi-liquid, semi-solid state, appeared, the hammer began to forge it.

Completely without any strategy, relying solely on his Devil Fruit ability, Iron Hammer unleashed a four-way hammer attack, combined with his large hand covered in Armament Haki.

He started hammering the lava wildly.

They quickly hammered the lava together into a block.

"Simply using lava won't work... Hmm... Will sprinkling salt work? Let's give it a try."

Iron Hammer skillfully sprinkled flux on it, but the magma was too hot and full of destructive power, and the flux was directly turned into slag.

"Well, it seems ordinary methods won't work. Let me think..."

"Raising the temperature caused it to reach a semi-liquid, semi-solid state... The Flame-Weaving Stone is needed..."

"For fusion shaping, mithril is worth a try."

"As for hardness, diamond..."

Without further ado, Iron Hammer took out the Flameweaver Stone, Mithril, Diamond, and other materials and placed them on the lava block.

"I'll smash it!"

"Duang!"

The hammers from all directions were activated again.

"Let's get this going!"

Fearing that the hammer might not reach the required temperature, they even utilized the power of the hammer's sparks.

For a moment, the sounds of hammering and roaring flames continued from behind Marineford.

Even the headquarters building could hear it very clearly.

Ms. Crane was the first to notice the anomaly and went to the window to look out at the back of the castle.

"Is that a hammer making that noise?"

He then immediately went to the old man's office.

Unexpectedly, she ran into Sengoku, who shared the same thoughts, in front of the old man's office.

The two exchanged a glance and then pushed open the door to enter.

Old Kong was also by the window, looking in the direction of the hammering sound.

"You're here! Come and see, that kid Iron Hammer is probably forging some kind of weapon again."

"This is quite a commotion."

The number of onlookers increased instantly, and the three high-ranking officials stood by the window, observing through their Observation Haki.

Moreover, the aura of flames was gradually rising.

As time went by, Iron Hammer's forehead was covered in sweat, but his eyes gleamed with excitement.

Finally, through his efforts, the magma was gradually shaped into the form of a giant axe.

Iron Hammer, panting heavily, looked at his work and nodded in satisfaction.

However, he did not stop, but continued to use his ability to gently tap and adjust the details.

Finally, he melted the remaining material and poured it onto the axe handle to make it stronger.

At that moment, a powerful aura emanated from the axe, as if the surrounding air had been ignited.

As Iron Hammer felt this power, a proud smile appeared on his lips.

"It's a success!" he whispered, his voice filled with joy.

"Huh? Is that a battle axe? That's impressive!"

A deep, surprised voice suddenly rang out from the side.

A Zephyr was standing at a distance, watching silently.

"I knew I could feel several eyes on me. It seems that besides you, Professor Zephyr, it must be Old Man Kong and the others."

"Fine, look if you want, but don't bother me, this isn't over yet!"

The forging process was in its final stages, and the hammer dared not slacken its efforts.

The shaping was successful, and the next step was quenching, but a problem arose.
