I just returned to Konoha and found that all my clan members were gone.

Sasuke and the other man were surprised. They didn't expect that the other party, who was not even as good as a Genin, would discover the traces of themselves and Kisame, even though they did not try to hide themselves.

"Alas, it seems that my feeling was right, there are still two people."

When Sasuke and the others showed up, the other party was surprised, because it turned out that they were just bluffing.

"Can I slash this guy, Sasuke?"

Kisame didn't expect that he was fooled by an ordinary person and felt unhappy.

Sasuke rubbed his brows, suppressed the urge to hit someone, and persuaded Kisame.

"Wait a moment."

"So it's a ninja? I thought someone had their eyes on my things."

The middle-aged man was disdainful when he saw the two men. In his impression, ninjas were all poor people and would not use the things they forged if they were of no use to themselves.

"Isn't it a bit too hasty to directly draw a conclusion without knowing the reason?"

Sasuke walked straight forward and stated his purpose.

"I heard you built some kind of weapon that's pretty powerful."

"Humph, it's rare that you have such good vision. It's just a semi-finished product. I haven't finished it yet."

The man was not as humble as before in front of Sasuke. He didn't think any ninja would be interested in this.

"Which village are you from, Kumogakure, Kirigakure, or Konoha?"

The Iron Country is relatively close to these countries, while the Sand Village and the Iwagakure are even farther away, so it is normal to think this way at the beginning.

"Neither. We are from the Hidden Rain Village."

Sasuke took out a Amegakure forehead protector from his arms and gestured. In order to carry out the mission, Kisame did not even wear the rebel ninja's forehead protector, so Sasuke specially got a Amegakure forehead protector.

"What? It turns out to be Hanzo's man."

The man was even less interested. Although Hanzo was famous, Yugakure was not famous at all and was not even considered a big country.

The people in the ninja world are still unaware of Akatsuki's hiding in Amegakure. They still think that Hanzo is still the controller of Amegakure.

Sasuke didn't explain too much, but said in a somewhat tough tone, "Let's take a look at your newly developed weapon."

"As you wish."

The man knew that he was no match for the other party. Although he felt unhappy with the ninja, he did not stop him. He just opened the door and walked in.

Sasuke and Kisame went straight in and the man pointed to the backyard and said.

"My son is still debugging there. If you want to watch it, you can go wherever you want. I'm going to take a rest."

After saying that, he left without caring about Sasuke and the other man's feelings and just left them there.

Sasuke went from being a little impatient with this person at the beginning to becoming a little puzzled as to why this person hated ninjas so much.

With these questions they entered the family's backyard.

When he reached the backyard, Sasuke realized that his initial estimate was too low.

The family's backyard was larger than where they lived, about half the size of a playground, and several young men were tinkering with something on a strangely shaped machine.

That mechanical Sasuke had never seen before. It had a huge base connected to countless batteries. There was an operating table on the base with a display screen showing various parameters. There was a metal object similar to a speaker in the front of the operating table.

"Is this the weapon that guy was researching? How can he use it when it's so big?"

Kisame asked in confusion. It was very difficult to move this thing, and Kisame couldn't figure out how to use it to fight.

"Test No. 133, ready to begin!"

A dark-skinned man next to the machine began to give orders. He looked less than 20 years old, and his face was somewhat like the middle-aged man Sasuke had just seen. He must be that man's son.

Under this man's command, the others began to act in an orderly manner. Sasuke saw that the battery connected to the base began to discharge current and continuously began to transmit it to the machine.

Kisame and Sasuke both stopped to watch, they also wanted to know how to use this thing.

As the current continued to flow, the indicator lights on both sides of the operating table began to flash continuously, and the display screen on the operating table kept beeping.

The horn-shaped metal port at the front began to condense a huge amount of energy, and the light from the port became increasingly dazzling, making it impossible to look directly at it.

Finally, as if the energy could no longer be controlled, a strong electric current was emitted directly from the port.

The electric current concentrated fiercely on the target fifty meters away, turning it into powder in an instant. Just as Sasuke and Kisame were surprised by the power of this thing.

The electric current began to thin rapidly after it exceeded seventy meters, and disappeared completely before it even reached a hundred meters.

Boom—

Before Sasuke could come to his senses, an explosion came from the other end of the machine. He saw that the horn-shaped metal object exploded and the front end was blown to pieces.

Even if no one else said it, Sasuke could see that the experiment had failed.

"This thing..."

Kisame didn't know how to comment on it. He was also shocked when the strong electric current was emitted, but he didn't expect that the power was so weak. What's the use of this thing if it can only reach fifty meters?

Black flames were emanating from the machine, and many experimenters began to put out the fire skillfully. It seemed that this kind of thing had happened more than once or twice.

The dark-skinned man saw Sasuke and the other man after being reminded by his companions, so he dropped his experiment and ran over.

"I'm sorry to make you laugh. My father asked you to come here to look at the investment, right?"

The man, who already had dark skin, became even darker now, and he ran over without even having time to wipe his face.

"It's just a little disappointing, so to speak."

Even if Sasuke didn't understand, he could tell that it must have cost a lot to make this thing, but it only had this much effect. It was definitely disappointing.

"Haha, actually, now we just need to break through the durability of the barrel and make the current gather for a longer time, and the range will probably double."

The man touched his head awkwardly. The performance of the unfinished product was indeed disappointing.

"What's this thing called?"

Sasuke asked.

"Call the electromagnetic cannon. Wait, weren't you invited by my father?"

The man looked puzzled, knowing his father's character, he understood that if his father wanted to recruit people, he would definitely praise this thing to the sky, but in the end he didn't even know the name of the person who came.

"We took the initiative to look for your father, but when he heard that we were ninjas, he asked us to come directly here."

After hearing what Sasuke said, the man immediately understood and explained.

"Because we were born in the Iron Kingdom, which is a country of samurai, it is inevitable that father has some opinions about ninjas. Don't take it too seriously."

"It's okay. I haven't asked for your name yet."

Sasuke waved his hands. He understood that before the ninjas, the samurai had always been in control and the ones who originally carried out the missions were samurai. Now the samurai have fallen on hard times, so it is normal for them to have some opinions about the ninjas.

"Look at me, I've forgotten everything. My name is Akutagawa Ryuichi, and my father's name is Akutagawa-do."

Akutagawa Ryuichi stretched out a hand and said with a smile, knowing that the other party was a ninja, his father must not have told his name, so Ryuichi said his father's name as well.

Sasuke looked at the other person's dusty palm and felt a little unhappy. He had no habit of shaking hands with other people, so he ignored the other person and spoke directly.

"Electromagnetic cannon. The name is fine, but its effect is probably not as good as that of a Chunin. This thing must be very expensive."

Long Yi withdrew his hand awkwardly and said with a laugh.

"I told you it's just a semi-finished product, as long as..."

"Even if it's like what you said, the distance is only doubled to a little over a hundred meters. I've seen the charging time of this thing. Even a Chunin can run two round trips in this amount of time. It's impossible for others to stand still and let you hit them."

"We have thought about what you said. As long as we have enough research and development funds, we will definitely solve this problem!"

Long Yi said unconvincedly that this thing embodied all the hard work of him and his father, how could it be easily denied by others.

"I've seen that most cannons use batteries as their energy source. This is expensive. Have you ever thought about changing to another energy source?"

Sasuke walked to the electromagnetic cannon. The fire produced by the explosion had been extinguished by the experimenters. He looked at it carefully.

"Another one?"

Long Yi really didn't think about this problem, and batteries were the only solution they could think of.

"Actually, this thing doesn't have to be called an electromagnetic cannon. It can be called a chakra cannon."
