Kakashi looked at Kuragami Uchiha. To be honest, their situations were very similar to some extent. They both had the Sharingan and used Lightning Style as their main attack method. They also had some experience in swordsmanship.
Therefore, Kuragami Uchiha should have a way to help him improve his strength.
"Although you have used the Sharingan that my cousin left you very well, you are too obsessed with the ordinary Uchiha fighting style."
Kuragami said: "It is easy to copy ninjutsu with the Sharingan, but your Chakra cannot support the huge consumption of temporarily copied ninjutsu. You know, even the real Uchihas only used a few ninjutsu that they had practiced a lot in their daily lives when facing a strong enemy." Kuragami Uchiha said.
"So, what you should improve now is your control over Chakra."
After saying that, Kuragami Uchiha made a seal.
Lightning appeared beside Kuragami and then condensed into a human figure. Then, the details of the person transformed by the dark blue lightning gradually became clear. Kakashi was surprised to find that the lightning man in front of him was exactly the same as him.
At this time, the expression on the face of the lightning man in front of him also changed, and it was exactly the same as his.
"This…"
Kuragami Uchiha's move shocked Kakashi so much that he couldn't help but pull up his forehead protector and open his Sharingan.
What Kuragami Uchiha used was not a lightning clone or even a ninjutsu.
It was simply a fine control of the form and nature of Chakra. Although this method was useless in battle, this kind of fine control that can reach every detail is probably not inferior to Tsunade, who has always been famous for her control over Chakra, right?
Kuragami snapped his fingers, and the man formed by lightning disappeared instantly.
Kuragami smiled and said to Kakashi: "If you can achieve this level of control, then you'll be able to do something like this with only a tiny amount of Chakra."
Kuragami took out a kunai from the tool bag and then used a little lightning Chakra to build an electromagnetic field.
In Kakashi's surprised eyes, the kunai that was released from his hand was suspended in the air and then began to rotate sideways at high speed.
Kuragami Uchiha raised his hand and pointed in a direction, and then he suddenly clenched his fist.
The kunai flew out at high speed in an instant, so fast that even Kakashi's Sharingan could not catch it.
It reached a hundred meters away in almost the blink of an eye and hit the huge boulder heavily. The huge kinetic energy directly broke the boulder with a diameter of nearly one meter into pieces.
Kakashi looked at Kuragami in disbelief. Although any ninja above the level of Chunin could do the same thing, the flying speed of this kunai must have reached three times the speed of sound.
Even a Jonin who excels in speed cannot easily dodge it. More importantly, Kuragami had used barely any Chakra, less than what was required for even the most basic clone jutsu.
"How did you do this?" Kakashi asked.
"Kakashi, have you carefully explored the electric current brought about by the change in the nature of Lightning Style?"
Kuragami smiled: "The change in the nature of Lightning Style can produce electric current like natural lightning, and if the control is good enough, it can create a strong magnetic field. Only a little bit of Chakra is needed, and the constructed magnetic field can accelerate any metal material to the one I show. I call this trick a Railgun."
"If you can learn it, then your problem of insufficient Chakra won't be so big."
After that, Kuragami Uchiha took out a scroll, threw it to Kakashi, and said: "Go back and practice according to what is written on it. Except for me, you are the only one who can learn this technique. Without the dynamic vision assistance of the Sharingan, it is difficult to even aim. And most of my other clansmen have no talent for Lightning Style."
"This is too valuable."
Kakashi said after taking the scroll.
"If you think it's valuable, you can exchange it with your Chidori. I can use it to teach Sasuke. The ninjutsu I developed is not suitable for laying the foundation for children." Kuragami Uchiha said.
Kakashi heard this and smiled helplessly. The ninjutsu that he had worked so hard to develop in the past was used by Kuragami Uchiha to lay the foundation for children?
But after thinking about it, of all the things he had, except for the White Light Blade placed in the ancestral hall, only the Chidori was barely worthy of the ninjutsu that Kuragami Uchiha taught him.
"I will send you the scroll of Chidori before you leave."
Kakashi said.
"By the way, if you go to Village Hidden in the Mist, take this with you."
Kuragami Uchiha smiled, took off the Swift Thunder from his waist, and threw it to Kakashi.
"Is it necessary?"
Kakashi was a little puzzled after taking the sword. "I haven't practiced swordsmanship for a long time."
"This sword is not for you."
Kuragami Uchiha said with a smile: "For those rebel ninjas from Village Hidden in the Mist, as long as they see this sword, it will work better than any ninjutsu."
"Okay, I understand."
Although Kakashi didn't quite understand why Kuragami Uchiha said that, Kuragami Uchiha gave him the ninja sword that almost never left him, so there must be a purpose.
… … …
The next day, Kakashi received a report on the mission.
Just as Kuragami expected, alongside him, several of the fourth Hokage's former subordinates, such as Genma Shiranui and Raido Namiashi, were organized into a team to go to the southeastern border of the Land of Fire to assist the ninja troops at the border to clear out the rebel ninjas who escaped from Village Hidden in the Mist village.
That afternoon, Kakashi went to the Academy to pick up Naruto and took him to the Uchiha Clan territory.
"Kakashi-nii, where are we going?" On the way over, Naruto found that this didn't seem to be the way home and asked curiously.
"I have to go out to do a long-term mission during this period, so I ask Mikoto-sama to take care of you for a while."
"Huh?" Naruto was surprised to hear this and then said: "I can take care of myself."
