"If you encounter an emergency, just enter Chakra into Kunai like you just did."
After a pause, Naruto reached out and patted Karin on the head. "If you feel bored and want to chat with me, you can activate it and call me."
"Normal things are fine, it doesn't have to be an emergency."
Karin nodded vigorously, put the ninja bag on his chest, and finally there was a little faint blood on his face.
"I've asked the boss to deliver the food. I'm going back first!"
Naruto smiled slightly, took a few steps back and locked his mind on Flying Raijin Kunai who was behind Konoha.
"Whoosh!"
The next second, his figure disappeared from the room.
Karin stood there and looked at the position Naruto had just left for a long time.
She took off her glasses, wiped the blurred lenses with the corner of her clothes, and then put them back on.
He took out Pentagram Kunai from his ninja bag, placed it next to the pillow, then took off his shoes and got into bed.
Lying on his side and staring at Kunai for a while, Karin closed his eyes, curved his mouth silently, and said softly:
"Thank you, Naruto."
Konoha
back mountain
"Whoosh!"
When Naruto appeared, Good and Evil Perception automatically spread and swept around.
Everything is fine, no one is around.
"Practice first!"
"Multiple Shadow Clone Technique!"
Without wasting time, Naruto separated out two hundred Shadow Clone Technique, and began to focus on integrating Lightning-Nature Chakra into Rasengan.
Two hundred Shadow Clone Technique began to condense Rasengan in the palm of the hand at the same time, and then tried to import Lightning Release Chakra into Rasengan.
Once the properties of Lightning Release Chakra are successfully integrated into Rasengan and given the disappearing property, then Naruto will have an invisible killer move that cannot be tracked by conventional sensing methods in combat.
If the disappearing property can be further applied to Rasenshuriken, the ultimate Wind Release Ninjutsu, which was originally strong enough to instantly kill Kage Level, will turn into a deadly ghost.
Just when Naruto and two hundred clones were concentrating on Lightning Release Rasengan's practice, a tall figure swayed up the mountain.
Jiraiya walked to the back hill and saw at a glance two hundred Naruto holding Rasengan and entering Lightning Release Chakra.
"Naruto, are you adding Lightning-Nature Chakra to Rasengan?"
Jiraiya walked over curiously, folding his hands on his chest.
Naruto raised his head and saw Jiraiya, put away Lightning Release Rasengan in his hand and stood up.
"It turns out to be Pervy Sage."
"Well, I'm trying to see if I can integrate Chakra Nature Transformation into Rasengan to increase its upper limit of power."
"Oh?"
Jiraiya's eyes lit up when he heard this, and he said in a serious tone, "Integrating Chakra Nature Transformation into Rasengan is the advanced direction of Rasengan."
"When the Fourth Hokage project originally created this Ninjutsu, it was hoped that it would eventually become the carrier of Nature Transformation, but Fourth Hokage left early and the project did not have time to be completed."
"I also tried to integrate the fire attribute into Rasengan back then, and almost blew up a mountaintop of Mount Myoboku!"
"This is not a field that ordinary people can touch, but since you kid has a cultivation method like Shadow Clone Technique, there is no harm in giving it a try."
"But why don't you start with the wind attribute first? Instead, use the Lightning-Nature Chakra you just cultivated?"
"Wind-Nature Chakra merges into Rasengan and I'm done."
"What we are trying now is the thunder attribute."
Naruto spoke calmly.
"What?"
Jiraiya's eyes widened and his lips moved.
"Wind attribute Nature Transformation is integrated into Rasengan?"
"You're done?"
"When did it happen?"
"Why didn't I know?"
"You..."
"Just a while ago!" Naruto nodded.
Jiraiya took a deep breath, and then pushed back the urge to ask.
He has gradually gotten used to it.
Being serious with this kid will only make your blood pressure more and more unstable.
But from this point of view, Naruto's current strength has far exceeded the level that Chunin should have. When taking him out to find Tsunade, he can teach some higher-level Ninjutsu theories on the way.
"Pervy Sage, why did you come to see me?"
Naruto brings the topic back.
"One of Tsunade, Konoha Sannin, and also the granddaughter of First Hokage Hashirama Senju."
"We are going to find her and invite her back to Mu to serve as Fifth Hokage."
Jiraiya poked his chest with his thumb. "So this immortal decided to take you out for a long experience."
"Okay, when do you leave?"
"We will meet at the entrance of the village early tomorrow morning."
"I have already said hello to Kakashi. Your mission has come to an end for the time being. Please follow me out to practice."
"You continue to practice first."
"Pervy Sage, don't be late tomorrow." Naruto reminded.
"Only Kakashi will be late, and I will never be late!"
"I'm not of the same species as that masked man!"
Jiraiya Hearing this, he immediately walked down the mountain angrily.
While walking, Jiraiya suddenly stopped.
"Eh, that's not right."
"Didn't Naruto just say that he had integrated the properties of Wind-Nature Chakra into Rasengan?"
"How did this brat do it?"
"Why did I forget to ask? No, I must ask him carefully on the road tomorrow."
Jiraiya stroked his chin and thought for a moment, then waved his hand.
"Forget it, it's not too late to catch this guy tomorrow and ask him again. Anyway, the road from Konoha to Tanzaku Town is long enough, so there is plenty of time."
Thinking of this, Jiraiya wandered towards Konoha.
After Jiraiya left, Naruto continued to study Lightning Release Rasengan with two hundred clones.
time passes
When the sun slides from overhead to the edge of the mountain, the entire back mountain is dyed warm yellow.
When Shadow Clone Technique released itself due to exhaustion of Chakra, Naruto archived all two hundred training memories and then slowly opened his eyes.
The results of this whole day's practice are very subtle.
It is not difficult to integrate Lightning-Nature Chakra into Rasengan. Under the precise control of Absolute Control, Lightning Release Chakra can be injected into the rotating layer inside Rasengan as accurately as threading a needle. The stability and power improvement data are very beautiful.
But the problem lies in the vanishing property.
No matter how he adjusts the proportion of Lightning Release Chakra, adjusts the import timing, and adjusts the rotation frequency inside Rasengan.
Fusion Lightning-Nature Chakra's Rasengan can never disappear into thin air like Boruto's Rasengan.
On the other hand, Fusion Lightning-Nature Chakra's Rasengan will fly out with lightning, and when it hits the target, it will explode with the paralysis and penetration effects of Lightning-Nature Chakra, but it will not become invisible.
All day long, there was no sign of disappearing.
"What's wrong?"
"Why can't it be done?"
Naruto stood up, patted the grass on his knees, and frowned slightly.
He used Absolute Control to make every Lightning Release Chakra operation precise to the millimeter, and all parameters were adjusted to the optimal solution, but the disappearing characteristic just didn't come out.
This shows that the essence of the disappearing characteristic is not at the operational level of Chakra, but in another dimension.
Naruto dug out the memories of his previous life and compared them again.
The fact that Boruto's Rasengan will disappear seems to be directly related to his natural Jōgan.
Jōgan is the special pupil technique of Boruto, which can see through the connection of time and space and see the direction of Chakra. This level of eyes itself has spatial attributes beyond the conventional Ninjutsu system.
"If simply integrating Lightning Release Chakra Nature Transformation into Rasengan can make it disappear, then there is no way Minato Namikaze that developed Rasengan could not have been tried."
You must know that Minato Namikaze can even be researched by Tai Chi Rasengan. It is impossible not to try to integrate Lightning-Nature Chakra into Rasengan.
Kakashi has copied thousands of Ninjutsu, and Lightning-Nature Chakra is one of his main attributes. It is impossible that he has not studied it, which shows that this is not a simple Lightning Release problem."
"It seems that this road ends here for the time being."
Since Lightning Release Chakra Nature Transformation cannot give Rasengan the disappearing property, then Naruto will no longer take advantage of it.
