"It seems that the Kyuubi's Chakra has begun to leak out," Kakashi said.

  "Yeah, but this intensity is really amazing. It is just a tail, but it already has the aura of Jōnin. I wonder what happened if the Kyuubi is not split into half." Jiraiya said with emotion.

  Kakashi nodded as he is also very curious about how strong the intact Kyuubi was.

  The original Kyuubi had two powers, yin and yang. Now, what is in Naruto's body is only Yang half of the Kyuubi.

  But even if it was just the Yang half, during the war in the original work, Naruto with the help of Kyuubi could fight against five Bijū at the same time and still had the upper hand.

  If it is a complete Kyuubi, does that mean that all the other eight Bijū won't be his opponents?

  It must be said that when distributing the power of the Bijū, Sage of Six Paths is too biased towards the Kyuubi.

  Compared with the other Bijū, Kyuubi got the most power.

  "Naruto, how do you feel?" Kakashi asked.

  "It feels good, but there is a killing intent in my heart. There is also a burning sensation on my skin," Naruto said.

  "It seems that the current Naruto can now control the power of one tail freely." Kakashi muttered.

  "Yeah, after all, it's just equivalent to Jōnin's strength, so it is to be expected. Now, let's continue." Jiraiya said.

  Time continued to pass by.

  The Bijū Chakra Cloak on Naruto's body became more and more red, and after a while, the second tail appeared!

  Naruto only felt that the burning sensation on the skin was a bit stronger, but it was still bearable.

  Soon, the third tail grew out!

  "Jiraiya-sama, the speed of the strength is getting leaked is becoming faster," Kakashi said.

  Jiraiya's expression also became a little serious.

  He can feel that Naruto's strength is gradually approaching towards the Kage level strength.

  "The strength of the three tails is around Elite Jōnin. Then, is the fourth tail equivalent to the Kage-level strength?" Jiraiya muttered.

  "It should be correct, but it seems that Naruto can't hold it any longer."

  Naruto was already on all fours at this time, and with the Bijū Chakra Cloak on his body, he looked like a fox.

  The beard on his face became more obvious, his nails grew a lot longer, and even fangs appeared.

  "Aahhh!"

  Naruto roared, and a powerful wave of air shook the entire space!

  Kakashi narrowed his eye and secretly thought: 'The power of Kyuubi is really terrifying. It's just the third tail but it already has this level of strength. It seems that the fourth tail is equivalent to the Kage-level strength. No wonder Naruto can fight against Orochimaru with the fourth tail and still has the upper hand.'

  When Kakashi is still thinking, the three blood-red tails wrapped Naruto tightly.

  The skin seemed to be fading away little by little, and Naruto's appearance can no longer be seen.

  At this point, Naruto is like a small Kyuubi, his whole body appeared black and red, and his eyes became white.

  "Roar!"

  A roar like a beast came from Naruto's mouth!

  "It seems that the situation is a bit bad. Naruto can no longer control the Kyuubi's power after reaching the fourth tail and he already lost his reason." Jiraiya said solemnly.

  "Yes, the power that Naruto can control today is only up to the third tail. As for the fourth tail, he can't do it. In this case, I am afraid that it will be long before Naruto can completely control the full power of Kyuubi. Moreover, I am afraid that this way of mastering is not the right way. Right now, Naruto probably has already lost all of his skin. I heard that the Hachibi's Jinchūriki, Killer B has a good relationship with the Hachibi, and he can turned to Bijū anytime," Kakashi explained.

  "Become a friend with Kyuubi? Naruto can only rely on himself for that, but I now understand where Naruto's limits are at. In the future, I can also do some more focused training," Jiraiya said.

  "In that case, let's disperse the Kyuubi's Chakra from Naruto as soon as possible. I am afraid that his body will not be able to support it if he stayed in that state for a long time," Kakashi said.

  "Yeah."

  Just after Jiraiya responded, the four-tailed Naruto suddenly opened his mouth, and a little bit of red and blue Chakras condensed in the air.

  Kakashi was surprised and said: "Damn, Naruto is condensing Bijūdama!"

  Jiraiya was also surprised when he saw the terrifying Chakra that was condensed. If it hit him head-on, he knew that he would die without leaving corpse.

  Bijūdama was ready in no time, but the four-tailed Naruto didn't launch it directly, but swallowed it into his mouth.

  In an instant, the body of the four-tailed Naruto quickly swelled.

  "Not good! Get out of the way!"

  As soon as Kakashi's voice fell, the terrifying Bijūdama was spurted out of four-tailed Naruto's mouth!

  The Bijūdama moves towards Kakashi and Jiraiya.

  However, these two are powerful expert, so how can they be hit by Bijūdama when they are prepared.

  Bijūdama failed to hit any of the two, and finally bombarded the oesophagus of the Rock Lodging.

  In an instant, a big hole was formed on the stomach wall.

  But soon, the big hole was quickly repaired.

  "What a terrifying power. The defensive power of the Rock Lodging's oesophagus is strong but I didn't expect it to be broken by just a blow." Jiraiya murmured.

  Jiraiya now understands why Minato bet on putting the Kyuubi on Naruto's body at the end of his life.

  Because Minato knew the power of Kyuubi very well, after all, he was the man who slept with Kyuubi's Jinchūriki.

  Therefore, Minato knows that once Naruto fully mastered the power of Kyuubi, he will have the confidence to face the unknown enemy.

  "Jiraiya-sama, Naruto has lost his mind now, so we have to find a way to re-seal the power of Kyuubi," Kakashi said.

  "Yeah, I am already prepared." Jiraiya said, taking out a piece of paper from his pocket.

  "This is the sealing paper that can seal the Kyuubi's Chakra. We just need to stick it on Naruto's forehead."

  After Jiraiya finished explaining, he handed the sealing paper to Kakashi and said, "Kakashi, you are faster than me. After this, I will hold Naruto, I want you to take that opportunity to stick this sealing paper on Naruto's forehead."

  "Okay, no problem." Kakashi took it and moved to the side, waiting for the opportunity.

  Seeing Kakashi is ready, Jiraiya looked at Naruto.

  At this moment, Naruto has already lost his reasoning. He is on all fours, and his eyes were extremely hollow.

  "Sure enough, this kind of thing can't be done randomly."

  Jiraiya said as he rushed towards Naruto.

  But before he got close, Naruto's four tails turned into sharp weapons and shoot towards Jiraiya!

  Xiū xiū xiū!

  Seeing this, Jiraiya moved around flexibly, avoiding the tail attack.

  Jiraiya then began forming hand seals with both of his hands!
