Jiraiya's white hair instantly stretched, forming long white ropes, and flew towards four-tailed Naruto.

  Ninjutsu using hair is one of the major features of Jiraiya.

  With its powerful strength, it is also one of Jiraiya's most commonly used Ninjutsu.

  The long white hair formed the shape of a lion's head, and then entangles the four-tailed Naruto tightly.

  The four-tailed Naruto's limbs are completely restrained!

  "Roar!"

  The four-tailed Naruto screamed and snarled, trying to break free of Jiraiya's annoying hair.

  "Now!" Jiraiya shouted in a low voice. Hearing this, Kakashi used Shunpo directly and rushed towards Naruto.

  Holding the sealing paper in his right hand, he was about to stick it on Naruto's forehead.

  But, at this moment, the four-tailed Naruto struggled crazily, and the shackle formed by Jiraiya's white hair was broken directly!

  The white hair scattered, and then a paw was scratching towards Kakashi.

  Kakashi was shocked, and quickly backed away.

  The sharp claws swiped the clothes on Kakashi's chest, and in an instant, a shallow tear appeared.

  Kakashi get back to Jiraiya's side and Jiraiya asked, "Are you okay Kakashi?"

  "I'm okay. I just didn't expect that he would break free so quickly. He's really powerful." Kakashi said.

  "Yeah, it is much more troublesome than I thought. It will be hard to subdue him without causing damage to Naruto." Jiraiya murmured.

  Kakashi also nodded when he heard this.

  At this time, the four-tailed Naruto is indeed very strong, and the general Kage-level expert is probably not his opponent.

  But compared to Jiraiya and Kakashi, there is still a big gap.

  It is not difficult for them to kill Naruto, but the problem is that they want to subdue Naruto without causing any harm.

  In the original work, Jiraiya was even seriously injured by Naruto.

  It's not that Jiraiya couldn't defeat the four-tailed Naruto, but Jiraiya has to subdue him without causing major damage to Naruto. So the difficulty has risen by several levels.

  After all, Jiraiya's Ninjutsu is not suitable for capturing, and they are usually used to kill.

  With Jiraiya's strength, maybe the only one who can defeat him before the war is Nagato.

  Even Nagato himself admits that if Jiraiya knows his secrets, he will be the one who lose.

  "Jiraiya-sama, to restrict Naruto's actions, let's use Earth Release," Kakashi said.

  "Well, I will continue to try and hold him. You should find a way to get close to him, but be careful, the strength behind his attack is not a joke," Jiraiya said.

  "Don't worry, I know about it."

  Kakashi said, and he once again moved to the side.

  When Jiraiya saw this, he removed the oesophagus on the ground, and then went formed hand seals!

  "Doton: Yomi Numa!" (Earth Release: Swamp of the Underworld)

  In an instant, a swamp formed under Naruto's feet, and Naruto sank directly!

  "Roar!"

  The four-tailed Naruto released another roar. He is obviously angry at this time.

  The swamp gradually swallowed Naruto's body, and soon, only half of his body was left.

  The four tailed Naruto is now furious!

  The four tails thrust into the swamp abruptly, trying to get his body out.

  Seeing this, Kakashi narrowed his eyes, 'Now!'

  Using Shunpo, he directly rushed from behind Naruto, and then, he directly thrust the sealing paper on his hand onto Naruto's forehead!

  "Roar!"

  With a weak roar, the Kyuubi's Chakra on Naruto receded like a tide.

  All that was left was a weak Naruto, whose skin had been corroded by Kyuubi's Chakra.

  Kakashi picked up Naruto, jumped out of the swamp and landed next to Jiraiya.

  At this time, Naruto has already unconsious, and did not know what happened.

  "The Kyuubi's Chakra is really terrifying. It actually directly erodes the skin on Naruto's body." Jiraiya frowned.

  "It is indeed terrifying. The Kyuubi's Chakra originally has strong resilience, and using that kind of Bijuu Chakra Cloak will cause corrosive damage to his body. This action will cause great damage to human cells. I am afraid that if things go on like this, Naruto won't be able to live long," Kakashi said and then, green Chakra appeared in his hand as he starts to heal Naruto.

  "Well, it seems that this way of mastering is really not good. I have to think of another way." Jiraiya murmured.

  Kakashi took back his Chakra and gave up the treatment.

  Kakashi knew that this kind of injury can't be cured by his half-baked Medical Ninjutsu.

  "That's really the safest way. But we should need Naruto to grow up a little more before we can try another way," Kakashi said.

  "Yeah, you're right." Jiraiya nodded.

  "Let's go back first. With Naruto like this, I'm afraid it will take some time before Naruto can train again." Kakashi said.

  Jiraiya scratched his head and said with a smile: "It seems to be like that. Fortunately, I called you over this time. Otherwise, I'm afraid that it will be really troublesome."

  Kakashi smiled and didn't say anything.

  In the damp sewer, Naruto once again appears here.

  There is stagnant water on the ground, and a dark road ahead.

  Naruto was dazed, but there was a force that led him to walk forward slowly.

  Finally, he once again reached the huge iron cage, housing the huge figure.

  "Idiot, you're here." said Kyuubi coldly.

  Naruto was shocked when he heard this and reacted.

  "Smelly fox? Why am I here again," Naruto asked in surprise.

  "Idiot, I don't even know why you came here. How is it, isn't my strength awesome?" Kyuubi mocked.

  Memories started to flood into Naruto's head. After a while, Naruto reacted.

  "Smelly fox! It's you again, right?" Naruto yelled.

  "Hmph, it's your own fault. After all, you are the one who open my seal slightly and let my power leak out. Since you want to, then I can't let you down. It's just the power of four tails, but you already can't bear it. You're really weak." Kyuubi mocked.

  Naruto was furious when he heard this, but there was nothing he can say. After all, it was indeed his lack of strength that prevented him from mastering the power of the four tails this time.

  "Smelly fox! Just you wait! One day, I will master all of your power!" Naruto swears loudly, pointing at Kyuubi.

  "Oh? What an arrogant brat. Who do you think you are? Thinking that you can master the strength of the Legendary Kyuubi!" Kyuubi said with disdain.

  "Because I am Uzumaki Naruto! Smelly fox! One day, you will recognize my strength! After all, I will become the Hokage!"

  Kyuubi was slightly startled, and then said: "Boring."

  "Aaah! Smelly fox, what are you talking about!"

  "Get out, you're really noisy."

  With a wave of Kyuubi's paws, Naruto felt dizzy, and then fainted.

  "Sure enough, the reincarnations of Asura are all idiots."
