Following Kirabi into the waterfall, Naruto was pleasantly surprised to find that there was a very wide cave hidden behind the waterfall. This cave is obviously not naturally formed, the shape of the whole cave is a boxy square, the cave wall is flat and smooth, and it is obvious that there are traces of artificial excavation. Because there is no sunlight entering, the light in the cave is very dim, Li Xiao stood at the entrance of the cave and looked at it for the first time, and found that there were many huge stone statues in the cave, all of which maintained the posture of sitting cross-legged on the stone base, but there was one thing very strange: these stone statues all had no heads, and the incisions on the necks were smooth and flat, as if they had not made heads when they were made at the beginning.

"Wow! What kind of place is this? Naruto asked curiously.

"This is the place where the pillars of the past generations of people in Yunyin Village have practiced, and it is here that I learned to master the power of the tailed beast." Kirabi was at the forefront, leading the way.

Kirabi led the group to the innermost part of the cave, where the head of a beast was carved into the innermost wall, and the beast had a bloody mouth with a mouth full of stone fangs, as if it was roaring at its enemies, and it looked terrifying, its mouth wide open enough for an adult to stick his head into.

"Now, Naruto, stick your head in." Kirabi walked up to the beast's head and pointed at the beast's gaping mouth.

Naruto stared at the beast's big black mouth, and couldn't help but feel a little stunned in his heart, "Are you sure this is okay?" It doesn't close suddenly. ”

Kirabi slapped Naruto in the back, "Stop rubbing, Nine-Tails."

"Hey! It's not a joke, it's fine, right? Yamato also confirmed with Kirabi with confidence.

"If I say this is the only way to master the power of the Tailed Beast, do you stretch it or not?" Kirabi said that under his sunglasses, it was impossible to see what was hidden in his eyes.

Kirabi's words touched Naruto, and Naruto immediately took a deep breath and said loudly with determination, "Okay! I'm stretching! Then, before Yamato could stop him, Naruto stuck his head into the beast's mouth. Two seconds later, Naruto pulled his head out unharmed.

"How? What's inside? Yamato asked worriedly.

"There's a mechanism in there." After Naruto finished speaking, there was a sudden sound of gears rubbing against the wall, and then under the surprised gaze of everyone, the wall "rumbled" open - it turned out that there was a secret room hidden behind this wall.

This secret room is very spacious, accommodating twenty or thirty people, there is nothing in the room, it is empty, and it is a real "four walls". However, there is one thing that is very magical about this secret room, I don't know what kind of special stone the whole secret room is made of, its walls, ceiling and floor all emit a gentle white light, although there is no light in the secret room, but it is "brightly lit".

"Let's go." Kirabi led the way into the secret room, followed by Li Xiao and the others.

After entering the secret room, Kirabi turned around and said to Naruto, "Sit down, then close your eyes and concentrate, and you will see the Nine-Tails, just like at the waterfall."

Naruto sat cross-legged and asked suspiciously, "And then?" What am I going to do after meeting the Nine-Tails? ”

Kirabi: "When you see the Nine-Tails, touch the Nine-Tails' chakra with your chakra so that the chakras of the two of you will stick together, and then just pull the Nine-Tails' chakra out of its body." But again, there are risks associated with this practice, and if it fails, your chakra may also be dragged out by the Nine-Tails. ”

"Sounds like a tug-of-war!" The little sister shouted excitedly on the side.

"Oh! The little girl summed it up very well, that's right, it's a tug-of-war! Kirabi stretched out his hands, a cool little girl, and then continued to Naruto, "You and the Nine-Tails will have a tug-of-war with chakra as a bet, and the winner will win the chakra of the loser. As the saying goes, risk and reward coexist, the greater the risk, the greater the reward, once successful, the chakra of the Nine-Tails will always be at your disposal. What do you think? Naruto, do you dare to take this risk? ”

Kirabi's last words immediately aroused Naruto's fighting spirit, Naruto frowned, and said loudly with high morale: "Of course you dare!" Without further ado, let's get started now! ”

Li Xiao stood next to Naruto, and couldn't help but be a little enthusiastic by Naruto's high-spirited fighting spirit, Li Xiao liked Naruto's stunned spirit of not being afraid of heaven and earth.

"Naruto, I'll protect you." As soon as Li Xiao raised his hand, the AT force field instantly changed into a huge golden "box", enclosing everyone inside. Then, Li Xiao also sat down cross-legged in front of Naruto, and he said to Naruto with a serious expression. "Naruto, I can enter your spiritual world to help you, but because it is your spiritual world, I can't exert my full strength, so I can only try my best to assist you."

When Naruto heard this, he was overjoyed: "Akatsuki, thank you so much!"

Li Xiao grinned: "Thank you, you and I are buddies!"

Kirabi also said to Naruto, "Since Li Xiao has decided to enter your spiritual world to help you, then I won't interfere, too many people entering will also have an impact on your spiritual world." Naruto, now close your eyes, concentrate, and get ready to start. ”

"Good!" With that, Naruto closed his eyes.

Seeing that Naruto was about to start, Li Xiao also closed his eyes. His method of infiltrating Naruto's spiritual world is very simple, Naruto is sitting in his AT force field enchantment at this time, and the AT force field is essentially a spiritual force, so as long as Naruto himself does not reject Li Xiao, Li Xiao can easily enter Naruto's spiritual world.

When Li Xiao opened his eyes again, the environment in front of him completely changed, a huge dungeon appeared in front of Li Xiao, at the other end of the cage, the nine tails lay there quietly, their huge body was like an orange hill, and a pair of red eyes stared at Li Xiao coldly.

As soon as he opened his eyes, he saw the big face of the nine tails, Li Xiao was immediately startled, and involuntarily took two steps back: "Woo wow! ”

Then, Li Xiao suddenly felt a warm hand on his back, and he saw Naruto standing beside him with a smile of surprise on his face: "Xiao, you're really here!" ”

Seeing that it was Naruto, Li Xiao couldn't help but breathe a sigh of relief, and also laughed: "Can I still lie to you?" ”

This is the second time Li Xiao has entered Naruto's spiritual world, and Li Xiao has also entered once in order to save Jiraiya. Li Xiao first looked at the surrounding environment, the place where the Nine-Tails was imprisoned was still the same, a dark and damp dungeon, dark and dark, and shallow water on the ground slowly flowed from nowhere, just past the instep. Li Xiao turned his head to look at the Nine-Tails again, and the Nine-Tails were still the same old look, and the only thing projected from its red eyes was coldness and hatred.

Although I managed to borrow chakra from the Nine-Tails last time, it didn't seem to improve the relationship between the Nine-Tails and Naruto. Li Xiao looked at the eyes of the Nine Tails, feeling the hatred for humans seen in those eyes, and thought silently in his heart.

Nine-tails lay lazily behind the prison door, looked at Li Xiao with a pair of red eyes, and then said coldly: "It's you two again, what do you want to do when you come to me this time?" Want my chakra again? ”

Li Xiao and Naruto glanced at each other, and the two nodded understandingly. Before this practice, Li Xiao and Naruto had already discussed the countermeasures against the Nine-Tails, Li Xiao proposed to salute first and then soldiers, first try to use Naruto's mouth to influence the Nine-Tails, if it can succeed, it is naturally the best, then there will be one less big battle with the Nine-Tails, if it fails, then it is not too late for Li Xiao and Naruto to make a move.

Originally, Naruto was also very disgusted with the Nine-Tails, after all, because of the Nine-Tails, his childhood situation was very bad, but because he successfully borrowed Chakra from the Nine-Tails last time, and Naruto had let go of the hatred in his heart, so now Naruto's impression of the Nine-Tails has changed a lot, so he accepted Li Xiao's suggestion.

So now, in the face of the Nine-Tails' cold questioning, Naruto took two steps forward, he looked up at the Nine-Tails, his expression was serious, and he said sincerely: "Nine Lamas, Xiao and I came here today to be friends with you. ”
