Chapter 416: Open the Door and Release the 9-Tail

What Mito asked Naruto to prepare was naturally the Sage Mode.

After a few words with Mito, seeing that a fight was about to begin, Nine-Tails knew how powerful Naruto was in Sage Mode. If it were a different environment, he was confident that he would have no problem fighting Naruto, but now... It would rather lose the battle than the fight. Then Nine-Tails stopped talking, sank deep into the cell and began to gather strength.

"When you gain the Nine-Tails' Chakra, its consciousness will also erode you. You should have known that state more or less when you used the Nine-Tails' Chakra before. Don't get lost."

"Anyway, you should try to defeat the Nine-Tails first. The more chakra you extract from it, the weaker its resistance will be. It's a two-pronged approach."

In the past, when practicing ninjutsu at a high intensity or trying to enter the tailed beast state, Kakashi and Jiraiya would be as nervous as facing a formidable enemy, but this Uzumaki senior made it seem like controlling the Nine-Tails was a piece of cake... However, the strength improvement brought by the Sage Mode is incomparable to the past, which does make Naruto less worried.

"Okay! Then I'll get started."

"In your mental space, be more confident in your actions."

Sasuke gave one last instruction, and Naruto responded by removing the seal, then twisting the "key" in his hand towards his abdomen, unlocking the seal on the prison door.

Minato left a crack in the seal to let Naruto get used to the Nine-Tails' chakra from a young age. Jiraiya wanted to do something, so he opened the crack a little wider. In addition, Naruto had never been able to maintain the formation, so the Nine-Tails gradually wore away the seal. Before the seal was opened, Naruto could get in touch with the Nine-Tails' chakra in small amounts, so the Nine-Tails could naturally absorb energy from the outside world and store it up, rarely using it.

If we were to say how strong this half of the Nine-Tailed Fox is now, it would probably be at least 7 or 8 points.

The prison door opened wide, and a huge fox head quickly poked out from the darkness. Naruto, who was in the state of a sage, was always on guard, so he easily dodged it. However, the Nine-Tailed Fox did not roar or yell as usual, and opened its mouth without intending to bite...

The moment the bloody mouth opened, a small-sized Tailed Beast Ball that had been stored in the mouth quickly expanded to a diameter of about 10 meters and quickly rolled towards Naruto who was dodging. The seemingly clumsy Tailed Beast Ball showed an anti-intuitive ballistic speed.

Naruto jumped up, creating several gusts of wind, and used the reaction force to fall to the ground, passing by the Tailed Beast Ball.

The huge Tailed Beast Ball continued to fly straight to the edge of the spiritual space...

Sasuke, who was watching, suddenly remembered something. His pupils shrank suddenly in fear, and then quickly turned into Mangekyō Sharingan.

Does the fight in the spiritual world have any impact on the outside world?

It would be strange if there was no effect. The energy in the spiritual space was real and fake, but such a big tailed beast ball was a solid ball of chakra. The Nine-Tails sprayed out, but Naruto did not absorb or disperse it. Sasuke didn't dare to believe that it disappeared out of thin air. The conservation of energy is also a law in the ninja world.

As his vision left the spiritual space, a violent chakra burst out from Naruto's body. Susanoo only stretched out one hand and quickly held Naruto. Susanoo had not yet reached its complete state, and chakra squeezed out from between its fingers and surged in the house.

Fortunately, with Naruto as the container to filter it, the Tailed Beast Balls in the spiritual space were relatively scattered in reality, and Sasuke stopped it in time without any losses.

The floor, walls, and ceiling were faintly lit with runes and chakra pathways, which were also connected to Susanoo. The chakra that overflowed in the room was quickly absorbed and returned to the energy cycle of Yakumo Castle.

"What happened? Did Kyuubi's attack just now affect the outside?"

Karin noticed something was wrong and followed Sasuke out. Fortunately, this little accident did not cause any serious consequences.

"It's solved. It's really worrying."

Even if Yakumo Castle has a head of steel and bones, it will definitely not be able to withstand the torment of the tailed beasts. If Sasuke wants to have a big family and a big fortune, he naturally has to pay a price for it, and this will also lead to new weaknesses.

Susanoo did not retreat, and Karin also set up a temporary barrier to intercept any accidents that might occur later. When Naruto returned to the spiritual space again, he and the Nine-Tails were already fighting fiercely.

Sasuke had no choice but to put forward his idea in a weak voice. His voice was not loud and he did not care whether the man and the fox who were fighting fiercely could hear him. It sounded more like he was complaining.

"How about you two stop for a while? I'll take you to another place to fight again?"

They should have been sent to the desert to fight in the first place...

"They've already started fighting, do you think they can stop?"

"They were fighting in my room, I wasn't afraid, so why are you afraid~"

Even if the room was destroyed, it was Sasuke who funded it, and it was not Mito's fault. It was easy for him to talk without any pain, and it was obvious that he was making fun of him. He looked at the Nine-Tails fighting for a few more times, and when it found his gaze, the corners of its mouth were raised. Sasuke felt that the Nine-Tails might be deliberately pitting him... In this situation, who could he choose to support?

The battle didn't last long. Naruto's Sage Mode could only last for 5 minutes at most. With dense yellow hair, waving balls and various ninjutsu, the high power output of the battle made the Sage Mode last even shorter. The Nine-Tailed Fox played whack-a-mole under the suppression of the formation, and eliminated countless shadow clones, but due to its huge size, it was inevitable that it could not take care of everything.

Although Mito said that she would not take action, Naruto had taken advantage of the time, place and people from the very beginning. During the fight, he dragged the chakra out of the Nine-Tails, and finally a trace of the Nine-Tails' chakra reached Naruto.

Defeating Kyuubi was always the easiest.

At this moment, the Nine-Tails suddenly stopped resisting, allowing a large amount of its own chakra to flow smoothly into Naruto's body. Naruto's shadow clone was still attacking the Nine-Tails, but as the chakra of the original body went out of control, the movement suddenly stopped and disappeared, and then Naruto began to transform into a tailed beast.

"It's not that easy to control my chakra!"

As the Nine-Tails' chakra intensified his emotions, Naruto began to become irritated and angry.

Although Sasuke accompanied Naruto for a while during his growth period, it must be said that Sasuke also led Naruto to face a lot of the dark side of Konoha. Naruto's negative emotions accumulated due to his excessive pursuit of recognition from others, although he tried his best to be lively and outgoing, and at this moment he had a way to vent.

Naruto entered a deeper spiritual world in his own spiritual space, and was stuck with all the negative memories of the past.

What is different from previous tailed beast transformations is that this time the Eight Diagrams Seal is completely opened, so along with the Nine-Tails' chakra entering the body, there is also...

Under the stares of the three people nearby, the Nine-Tailed Fox was very "refined" and did not continue to attack. He was even too disdainful to try a sneak attack (in the spiritual world, he probably couldn't kill anyone even if he tried to do it). That's right, there were only so many tests, and he didn't win anyway. As long as Naruto could wake up on his own, it would be a smooth journey.

But whether the battle continues is not up to the Nine-Tails unilaterally. Before Naruto wakes up, the Uzumaki ancestral diamond chain bursts out from his body. This very familiar chakra is obviously not from Naruto. It was clearly agreed to be a one-on-one fight. The Nine-Tails roared the name of the caster.

"Kushina!"
