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

Uehara Shu looked towards the corner.

There are a lot of materials displayed here.

And among them was a small piece of chakra metal.

Chakra metal is very rare.

Even Asuma's status and position in Konoha couldn't be improved much.

However, Uehara Osamu was, after all, the head of the forging department in Kirigakure.

A master blacksmith who forged numerous ninja tools.

Uehara Shu could still produce a small amount of chakra metal.

"The technique of combining earth and fire in smelting!"

The effect of the combined lightning and fire smelting technique was called lightning transformation by Uehara Shu.

The technique of combining earth and fire in smelting can increase the solidity of materials.

Uehara Osamu's idea was to use chakra metal to create a circuit.

Next, the ordinary materials were forged into two blades.

The circuit is clamped between the two blades to form a broadsword.

Because of the limited material in the middle circuit, Uehara Osamu was worried that the impact and vibration of the broadsword during combat would affect the circuit.

Therefore, the more solid and resilient the circuit, the better.

"Breathing Training Method!"

Through repeated forging, the chakra metal became even more resilient.

Then, only the part that is shaped into a circuit remains.

No quenching, no annealing, no polishing required.

Before long, Uehara Osamu had shaped the chakra metal into the form of an energy storage circuit.

It looks like a crooked wire.

Uehara Osamu directly grasped the circuit.

Chakra input.

"boom!"

A burst of force erupted.

Uehara Shu's eyes flickered.

"Because there is too little chakra metal, this energy storage circuit can only last for a short time, unlike the Blade of Destruction which can store energy for as long."

In other words, while an explosion of chakra is possible, the amount of chakra used in that explosion will not be as much as that of the Blade of Destruction.

"However, adding the inherent power of the Rock Stream itself won't be bad either."

If conditions allowed, Uehara Shu would naturally prefer to use more chakra metal.

However, there's only so much chakra metal.

"Forge the blade, assemble it, and give it a try."

Uehara Shu returned to the corner and retrieved a large piece of ordinary metal.

First, the Chakra Fusion Technique.

Rebreathing and training method.

When shaping the blade, Uehara Osamu's idea was to use a one-piece molding method, with the blade, guard, and handle all made from the same piece of material to maximize the strength of the broadsword.

They did not use the method of merging two knives into one.

Instead, they bent a piece of iron plate over.

A gap is left in the blade.

In the middle, Uehara Osamu deliberately created a groove to correspond to the shape of the circuit.

Only after the circuit is placed inside is it hammered again to completely eliminate the gap in the middle.

Next, pound the blade area.

The repairs are being carried out slowly.

Let this iron plate gradually transform into the shape of a broadsword.

"Quenching!"

A large amount of water mist was released.

Uehara Osamu placed the quenched broadsword in a flame to slightly heat it, reducing its brittleness and increasing its toughness.

"The Immortal Refinement Technique!"

With the polishing finished, this broadsword is officially complete.

This took up almost an entire day of Uehara Osamu's time.

However, since this was the first time it was being built, Uehara spent some time thinking and making adjustments during the repair process.

If the test results are good.

Then the subsequent development process will inevitably be much more efficient.

Furthermore, it is not necessary for Uehara Osamu to complete the entire process.

The second group of people, including Arasen, can also participate.

Currently, the forging department has three blacksmiths besides Uehara Osamu.

The production capacity of surgical scalpels alone is already quite sufficient.

Because the profits were still acceptable, the forging department didn't experience much pressure.

However, it would be incorrect for the forging department to only have scalpels as its business in the future.

If the Land of Iron also manages to break through the Scalpel Project.

Even if the quality of the scalpel is inferior to that of the scalpel from the Kirigakure forge.

However, as long as the price is low enough, the effect of bad money driving out good money can be achieved.

Uehara Osamu had seen many such examples in his previous life.

The broadsword was the second project in Uehara Osamu's plan.

"I created the circuit; the people of the Land of Iron simply don't know how."

"However, I need to do something with the circuit."

"Let the circuit automatically break when the broadsword cuts through."

"Otherwise, if someone else finds a broadsword, they can simply copy my circuit."

"It's like a ninja who gets a Sharingan from the Uchiha clan and can just plug it in and use it."

"I need to add this restriction to the loop."

"It's like the Caged Bird Seal of the Hyuga clan."

Uehara Osamu arrived at the training ground with his newly completed broadsword.

Both hands gripped the knife handle tightly.

Then he swung his knife fiercely at the target opposite him.

At the same time, chakra is inputted.

"boom!"

In addition to the slashing motion, there is also a considerable impact force that erupts at the moment the blade strikes.

Therefore, the target in front of Uehara Osamu was not broken in two.

Instead, it simply shattered.

"not bad."

Uehara Osamu nodded.

"It's better than a single circuit. With the blade as a support, the circuit performs even better."

"The impact of this attack is comparable to that of ninjutsu."

"The power of the broadsword was already very strong when it was charged up, and with this added, it will only become stronger."

"In terms of defense, apart from the broadsword, it depends on the user of the broadsword."

"As for the counterattack, it's the best I can do with the limited materials available so far."

Uehara Osamu put down his broadsword.

"However, there are a few minor areas that still need to be revised."

"Yoshikame Hoshigaki said that when it is necessary to retaliate, one should be able to take care of what is behind them."

"Then the handle of the broadsword can be extended slightly."

"but"

Uehara Osamu suddenly realized a problem.

That is, if chakra power is also released at the hilt of the sword, then it is very likely to accidentally injure the user.

The user would certainly not point the handle of the knife at themselves.

The problem is that during a battle, the situation is not always under one's control.

Instead, there will be many unexpected situations.

"If we want to increase the explosive power of the hilt, then we don't have to make it into the shape of a broadsword, but rather into the shape of a horse-slaying sword, greatly extending the hilt."

"In this way, it will be much less likely to accidentally injure the user."

"However, another problem arose immediately afterward."
