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

One is enough.

"it is good."

Kakuzu breathed a sigh of relief, and his expression softened.

"Let me explain it to you first, and then I'll demonstrate it for you."

"it is good."

Kakuzu's explanations were as meticulous as ever.

It's expensive.

But it's worth the price.

As someone who isn't short of money, Uehara Shu isn't afraid of high prices, but rather that the other party will take the money and not do the job.

Half a day passed, and Kakuzu had finished his explanation.

"Next, I will teach you this Lightning Release ninjutsu, called Lightning Release: Hand Grenade."

Osamu Uehara: "???"

Hand grenade?

The grenade that's similar to a hand grenade?

Kakuzu continued, "This ninjutsu is a lightning release technique that I stole from Kumogakure. It involves condensing lightning release chakra in the palm of your hand and then activating it."

"It looks like a rope, but it also looks like a snake."

"It will entangle itself around the other party."

"Once it hits, it will cause paralysis."

"If you use enough chakra and the opponent is weak enough, you can cause more damage."

"I named this ninjutsu myself."

"I don't remember what the place is called exactly."

Uehara Osamu thought to himself, "No wonder he's so casual."

"Alright!"

After saying that, Kakuzu began his demonstration.

Chakra condensation.

Immediately, a chakra rope appeared from Kakuzu's hand.

Under Kakuzu's control, it attacks the wooden target opposite.

Even if wood is an insulator.

However, lightning can also cause damage when the voltage is high enough.

A wooden target is not an absolute insulator.

It's just that the resistance is relatively high.

"Snapped!"

The target crumbled instantly.

"remember?"

Kakuzu withdrew his gaze and looked at Uehara Shu.

Uehara Shu closed his eyes.

Kakuzu sat down to one side.

Based on his previous experience, Kakuzu felt that Uehara Shu would need at least ten days, or even longer, to learn this ninjutsu, and could wait patiently.

But soon, Uehara Shu opened his eyes.

"Lightning Release: Hand Grenade!"

Uehara Osamu felt that this name was not quite right, but for now, he would still follow the name provided by Kakuzu.

The next moment, something happened that surprised Kakuzu.

Kakuzu saw that Uehara Shu had successfully condensed Lightning Release chakra in his hand.

And this lightning chakra successfully transformed into a bolt of lightning.

It turned into a shape similar to a rope.

"Snapped!"

The target in front of Uehara Shu was attacked and shattered.

Kakuzu's eyes widened.

He first looked at the target, then at Uehara Osamu, and then at the target again.

Kakuzu wore an expression of disbelief.

Is this person really the same one from last time?

You learned it after listening to it once and watching it once?

Why was it so difficult to learn the Fire Release technique last time?

Could they be twins?

Was it intentional last time?

Or perhaps, he simply has a high talent for Lightning Release but a low talent for Fire Release?

But if you have such a high talent for Lightning Release, why did you learn Fire Release?

Why not just learn Lightning Release directly?

Kakuzu was completely baffled.

"Senior Kakuzu, do I consider this a mastery?"

Upon hearing Uehara Shu's voice, Kakuzu finally snapped out of his daze, his expression somewhat complicated.

"Learned."

"Thank you for your guidance, senior."

Kakuzu nodded, seemingly wanting to say something but holding back.

"Kakuzu-senpai, is there anything else you'd like to say?"

Kakuzu hesitated for a moment.

"Um, would you like to learn another Lightning Release ninjutsu? The price is negotiable."

Uehara Osamu raised an eyebrow slightly.

With his exceptional talent, Uehara Shu is all he needs is a single Lightning Release technique.

However, if Kakuzu is willing to teach more, Uehara Osamu wouldn't mind.

Uehara Shu remembered that Kakuzu possessed a very powerful Lightning Release technique.

Even if I don't need it myself, teaching it to Ringo Ameyuri should at least help improve her strength.

"Alright, Kakuzu-senpai, what other Lightning Release ninjutsu do you have?"

"A high-level Lightning Release ninjutsu, Pseudo-Darkness, but it will also be more expensive."

The professor's use of Fire Release to make money was a source of great torment for Kakuzu.

But this time, the professor's use of lightning release was completely different.

Kakuzu didn't want to miss this easy opportunity to make money.

However, Kakuzu didn't know much about Lightning Release.

There are only two in total.

Uehara Shu started bargaining.

Kakuzu offered to teach this course, and Uehara Shu wasn't short of money, but he wouldn't just accept whatever price Kakuzu quoted. Doing so would not only result in greater losses but also invite contempt.

Before long, the two had agreed on a price.

Kakuzu began his explanation.

"False Darkness uses Lightning Release chakra to condense into the shape of a spear, sweeping from near to far. It requires a high degree of concentration of Lightning Release chakra and is highly destructive."

"If mastered properly, it can even penetrate rock."

"Moreover, it is extremely fast, making it very difficult for the opponent to dodge."

After saying that, Kakuzu gave a demonstration.

seal.

Open your mouth.

A beam of lightning shot out from Kakuzu's mouth.

"boom!"

It's like a laser.

Uehara Shu immediately thought of this.

Lightning is extremely fast, capable of hitting its target in an instant. It doesn't disappear upon impact but remains there as long as chakra can be continuously supplied.

In terms of appearance, it is no different from the laser beam emitted by a laser pointer.

But its power is many times stronger than that of a laser pointer.

After it is used, it can also be used as a ninja sword with an extremely long blade.

It can be used to kill people.

"Come and try."

As before, Uehara Shu closed his eyes, carefully recalled the events, and mentally rehearsed them.
