The water polo practice method, which Jiraiya came up with, is a more useful method for learning Rasengan.
Before the training began, he conducted a thorough test on Naruto's chakra control as usual.
The test results were somewhat beyond Jiraiya's expectations, and Naruto's basic skills were surprisingly solid.
However, he probably guessed that this was due to Uchiha Sasuke.
The method of using shadow clones to learn was really effective. Under the influence of the shadow clones, in just an hour or two, Naruto began to gradually master the tricks of water polo training.
But as time went by, Jiraiya also discovered the disadvantages of using shadow clones to learn.
As Naruto uses shadow clones more and more times, the chakra originally used to suppress the Nine-Tails chakra is gradually decreasing.
Jiraiya's expression turned serious.
Although he didn't say anything, his body was already in a state of war.
Unlike other people in the village who were afraid of the power of the Nine-Tails, he very much hoped that Naruto could control and control the power of the Nine-Tails.
And to take control, you must first get in touch.
He approached Sasuke and whispered:
"Sasuke, if something unexpected happens later, you don't need to worry about me. Just leave Naruto as far away as possible."
"leave?"
Sasuke frowned and stared at Jiraiya.
"I need a reason."
"You should know about the Kyuubi inside Naruto, right?"
Of course Sasuke knew this. He had even seen Naruto bursting out with Nine-Tails chakra when he fought Zabuza before.
"I know, what does this have to do with it?"
"I don't know how you discovered the method of using shadow clones to practice ninjutsu. This method is indeed useful for Naruto, but it also has disadvantages."
Jiraiya's expression became more serious.
"Naruto's chakra is very large, but the chakra that can actually be used accounts for only a small part of this chakra. Most of his chakra is used to suppress the nine tails' chakra."
"And the extensive use of shadow clones, a ninjutsu that consumes a lot of chakra, may awaken the chakra of the Nine-Tails."
"Naruto will go berserk."
"As more Nine-Tails chakra leaks, Naruto's sanity will decrease. He will gradually be controlled by the Nine-Tails in his body, lose his mind, and destroy everything he sees."
"If the Nine-Tails chakra is completely leaked, the consequences will be disastrous."
Hearing that Naruto was in danger of losing control when using the Shadow Clone Learning Technique, Sasuke immediately stood up and tried to stop Naruto who was still training.
But he was grabbed by Jiraiya beside him.
"What are you going to do?"
At this time, Sasuke looked at Jiraiya with evil eyes, and his Sharingan eye had already turned out the three magatama. As long as the other party did anything wrong, he would immediately turn on the kaleidoscope and use the Susanoo.
After all, they just met this uncle today, and Sasuke has not completely let down his guard. Now that he heard that Naruto might be at risk of being controlled by the Nine-Tails in his body, yet he stood idly by, Sasuke was already suspicious of him.
Jiraiya was very pleased to see Sasuke so concerned about Naruto's safety.
"Don't worry, don't worry. Since I didn't stop it, I will naturally be able to solve it. I just want to remind you that when a battle does break out, I may not be able to take care of you."
"The reason why I do this is because I hope Naruto can control the power of the Nine-Tails early."
"Although that power is a time bomb, if handled properly, it will be a powerful help to Naruto."
"Sasuke, you don't want Naruto to be feared or even discriminated against by others because of the Kyuubi, right?"
"I believe Naruto."
Jiraiya's eyes were very firm at this time, and his tone was calm, as if he was confident.
His words also made Sasuke fall into deep thought.
When Naruto was a child, he was shunned by others and gossiped about him. The image of him hiding alone by a river and meeting him by chance also appeared in his mind.
Even when he was in the ninja school, Naruto was not popular because of the Kyuubi.
Jiraiya's words convinced Sasuke.
The other party seemed to be sincerely interested in Naruto. Although Sasuke didn't know why Naruto had such high expectations for such a sudden appearance of the Sannin, he could feel the sincerity in the other party's words.
"knew."
Sasuke nodded, but did not show any sign of flinching, but looked more cautiously at Naruto who was still practicing in the field.
Approval does not mean full trust. If something unexpected happened, he believed that he would be able to rescue Naruto.
…
Sure enough, as time went by, after Naruto released his shadow clone again, the accumulated fatigue also fed back to Naruto's body. This time, Naruto did not fall down as usual, but stood sluggishly.
In place.
"Is it coming?"
Jiraiya took a deep breath.
Naruto's eyes turned blood red in an instant.
Today, because of the last round of the Chunin Exam, his mood fluctuated frequently, causing the seal in his body to loosen.
The Kyuubi in his body discovered this, so he kept testing and increased the power of chakra output. This wave of suppressed chakra became less, which directly allowed Kyuubi to seize the opportunity and violently output chakra.
A layer of scarlet chakra covered the surface of Naruto's body.
"Lovable Immortal, I feel a little strange in my body...I feel inexplicably irritable..."
Naruto also noticed the changes in his body. Although he tried his best to control it, the scarlet chakra became more and more. There was a voice in his heart that was fighting with him for control of his body.
At this time, his body surface was completely covered by the chakra coat leaked from the Nine-Tails, and two tails were formed swaying in the position of the tail spine ghost.
"It's two tails so soon..."
Jiraiya's face became more solemn, and he held the suppression talisman prepared in advance with one hand, ready to take it out at any time.
"Naruto, calm down, try to control this power, don't be controlled by it!"
Naruto in the second-tailed state looked ferocious, with his hands propped on his knees, as if he was trying his best to control his will.
"I...try my best."
With the encouragement from Jiraiya's words, the red chakra on Naruto's body faded slightly, and the chakra tail did not continue to increase.
Just when Jiraiya breathed a sigh of relief and thought he was done, a sudden change occurred.
The nine-tailed chakra on Naruto's body skyrocketed again and spread rapidly throughout his body. The chakra tails on his body jumped from two to four. Although he still maintained his human form, as the tailed beast chakra poured out, Naruto's
The skin was completely fused with chakra and covered with a dark red coat of tailed beast chakra.
Oops, Naruto still can't control this power.
Seeing Naruto in this state, Jiraiya felt something bad in his heart.
This place is not far from Konoha. If Naruto goes berserk here, the consequences will be disastrous.
Make a quick seal and slap the ground with both hands.
"Escape from Earth: Huangquan Marsh."
The swamp appeared at the feet of the four-tailed Naruto as he activated his ninjutsu, submerging half of Naruto's body.
Naruto, who was in the Four-Tails state, had completely lost his mind. Looking at himself deep in the mud, a dangerous smile appeared on his face covered with dark red chakra.
A claw made entirely of scarlet chakra protruded from Naruto's back and swung in the direction of Jiraiya and Sasuke.
"Danger!"
Jiraiya didn't care about his own danger. He only had time to push Sasuke away from him with one hand, but he was scratched hard by this claw.
