The Hidden Mist Blacksmith, forging the glory of the Ninja Sword Style!

"Thank you for bringing the materials. Please also thank the Mizukage for me, and everyone who worked hard to find the materials."

Goujujing smiled.

"Minister, this is what I should do. The Mizukage also hopes that you can forge more Zanpakuto. You are the one who works the hardest."

Goujujing spoke in a flattering tone.

"I will try my best to make good use of this material and not let everyone's efforts be in vain."

Uehara Osamu knew about Yagura's idea of ​​having Kyōkaku deliver the materials.

Instead of sending the ANBU ninjas, they sent Kyo Karatachi.

It's simply a matter of having Kyokuro Kyo come to the forging department to make himself known.

Currently, the Forging Department is more important than any other department in Kirigakure.

And it will exist for a long time.

The lifespan of a ninja sword is much longer than that of a ninja.

Yagura is now the Mizukage, which is good.

Therefore, the Karatachi clan gained a superior status in Kirigakure, and various resources followed one after another.

This was not Yagura showing favoritism.

Rather, it was inevitable as long as Yagura was in that position.

However, Yagura knew that he would eventually have to step down from the position of Mizukage.

The Hozuki clan was incredibly powerful back then.

But now?

The current situation of the Hozuki clan is somewhat similar to that of the Taketori clan before they were "extinct".

Yagura wanted to establish a closer relationship between the Karatachi clan and the blacksmithing company.

That would be of good help to the future of the citrus family.

However, Uehara Osamu wouldn't necessarily be against Yagura's arrangement.

It's just human nature.

With the materials in hand, we entered the forging room.

Uehara Osamu began to think.

"The material itself has fire properties, so the ninja swords forged from it must also have fire properties."

"Let's melt it down first and see how it goes."

Uehara Osamu placed the stone in the smelting furnace.

"Chakra Fusion Technique!"

Fire and lightning chakra entered simultaneously.

At this time, Uehara Shu had not yet mastered the Chakra Fusion Technique, which combines the three attributes simultaneously.

Moreover, Uehara Shu was not confident that he could master it in a short period of time.

Therefore, choosing a combined chakra fusion technique using lightning and fire attributes with high proficiency yields the best results.

"Crack!"

A crack appeared on the stone.

Then, the cracks grew larger and more numerous.

Until it completely burst open.

"boom!"

Impurities scattered around, while the metal in the center gradually melted and coalesced.

Under the influence of Uehara Shu's chakra, it was continuously refined and refined.

In fact, such a stone needs to be roughly refined before it can be smelted.

Now, Uehara Osamu has simply omitted the rough refining process.

By spending more time smelting, the rough refining process is bypassed, so that the material can be forged.

There are two reasons.

One reason is that, currently on Forging Island, apart from Uehara Shu, no other blacksmith would attempt to refine this stone.

It's not that the technical level is insufficient.

It simply requires time to study.

Another point is that Uehara Osamu himself needs to add equipment for rough refining.

Compared to the other two methods, Uehara Shuu's method of smelting instead of refining is more time-efficient.

Half a day had passed, and the metal had been almost completely melted down by Uehara Shu.

Take it out.

Only a small piece, about the size of an adult's fist, remained.

"From the perspective of the material's properties alone, it has enough hardness, but lacks toughness."

"It's too crispy."

"Because it has been transformed into a lightning shell, it can provide some protection, but it's not enough."

Uehara Osamu took some auxiliary materials from the side.

Some high-quality charcoal powder.

The carbon powder and the cooled metal are placed into the furnace.

A second smelting process is carried out.

They added carbon powder little by little, while keeping a close eye on the changes in the metal.

Toughness and hardness are often relative terms.

Too much hardness will inevitably lead to brittleness, causing it to break at the slightest touch.

However, excessive toughness also has its drawbacks.

When forging a ninja sword, one cannot go to extremes; rather, one must find the right balance.

It took another half a day for Uehara Shu to finally finish the adjustments.

A lump of metal is placed on the forging table.

"If we forge one kunai, we can make a little more."

"A dagger, that's about right."

"Let's forge it into a dagger."

Uehara Osamu made a decision.

Zudun's Hammer was taken out.

One-piece molding.

Next, another type of metal is wrapped around the handle, and then another layer of non-flammable, heat-resistant material is wrapped around this metal, carefully wrapped around it.

The handguards are made slightly larger to increase their sturdiness.

It makes it easier to engage in knife fights with enemies.

If the opponent is also a ninja who uses a ninja sword.

Besides Kirigakure, other ninja villages also have ninjas who practice the Ninja Sword Style.

Even those who are not ninjas of the Ninja Sword Style will often use kunai in battle.

"laugh!"

A mist appeared.

Uehara Osamu completed the quenching.

"It's a little too crispy."

So I annealed it and made some minor adjustments.

Carrying a dagger, he entered the polishing room.

"The art of refining immortal techniques."

Polishing is actually a very important step in the appearance of a ninja sword.

It might not be that helpful in improving the attributes of the ninja sword.

However, the appearance of the ninja sword is completely different before and after polishing.

The dagger, which had been somewhat dull just moments before, was now fully illuminated.

The entire dagger was fiery red.

It looks like there are flames burning on it.

The hilt, on the other hand, is a dark gold color.

Layers of patterns are stacked on the blade.

Uehara Osamu gripped the hilt of the sword and channeled chakra into it.

Immediately, flames burst into flames on the blade.

Uehara stopped inputting chakra, but the flames did not go out immediately; instead, they continued to burn for a while.

"The effect looks okay."

However, Uehara Osamu did not retract his ninja sword.

"Try this again!"

Uehara Osamu was not satisfied with simply forging the materials into a ninja sword.
