Reborn Naruto: Starting with its own system

After returning home, Naruto sat cross-legged and began to turn left to practice the "Phantom Spirit Technique". In this difficult year, he hardly stopped for a moment and devoted himself to practice. Finally, he successfully broke through to the 5th level of Qi training, and his own strength was almost the same as that of the Kage level.

However, as his training progressed, Naruto gradually felt unprecedented difficulties. It turned out that the spiritual power in the air of the Ninja Realm was almost zero, which made it impossible for him to use the spiritual power from the outside to improve his cultivation. He could only rely on his own chakra to practice, which was undoubtedly a huge challenge.

Although Naruto has the blood of the Uzumaki clan and is born with a huge amount of chakra, the chakra required for training is huge, and every breakthrough requires a huge amount of chakra. Gradually, his chakra reserves began to become stretched.

But Naruto was not discouraged by this, he knew that on this difficult road, retreating meant failure. He began to control and use his chakra more finely, constantly exploring new training methods, trying to break this dilemma.

Suddenly, an idea flashed through his mind. As the original owner, his own strength was not that strong, but he had a cheat. And at this moment, the cheat was lying quietly in his body.

Nine-Tails. The most powerful tailed beast, with almost endless chakra. Since your own spiritual power is not enough, then use it as a power bank.

Before dawn the next day, Naruto came to the edge of a cliff deep in the forest alone.

It has been four years since I came to this world. I have tried to communicate with the Nine-Tailed Fox many times, but each time it was like a stone falling on earth, with no response.

In his memories, the first time Naruto entered the sealed world inside his body was when he was learning summoning techniques and was thrown into the abyss by Jiraiya, putting him on the brink of life and death.

Then, without thinking any more, Naruto leaped forward, followed by a 720-degree spin and plunged headfirst into the abyss.

One second, two seconds, three seconds... the speed was getting faster and faster. In Naruto's perception, the bottom of the abyss was approaching rapidly.

I sighed helplessly in my heart: "Is it still not working?"

Just when his naked eyes could clearly see the bottom of the abyss.

A "thump" sound, like the sound of a heart beating violently, came to my ears.

Then everything went dark.

When he opened his eyes again and looked around, he found himself in a dark and damp passage.

Naruto was delighted: "It worked!"

At this time, I heard the roars of wild beasts.

Naruto walked quickly towards the direction of the roar, and soon he appeared in front of a large metal door.

On the metal door, a talisman with the word "seal" written on it was firmly stuck on it.

Just as Naruto walked closer to take a closer look, a head emitting red chakra appeared in the door - the Nine-Tails!

"Boy, come closer!" Nine-Tailed Fox's deep voice followed.

Naruto didn't think too much about it and walked straight towards the metal door.

Suddenly, the Nine-Tailed Fox inside stretched out its claws and stabbed Naruto fiercely.

With a "boom", Naruto stopped and looked at the Nine-Tails with disdain.

“Is there any point in you doing this?”

On the other hand, the Nine-Tailed Fox's claws were only 10 centimeters away from Naruto, fortunately there was a metal door blocking it.

"Hahaha, little brat. You are quite courageous. Come on, tell me your purpose."

Naruto did not respond to Kyuubi's question, but closed his eyes. The moment he opened his eyes, Naruto's eyes had changed, showing a three-magatama Sharingan.

In more than a year, Naruto has evolved the two-magatama Sharingan into a three-magatama Sharingan through the system.

Naruto stared at the Nine-Tails with sharp eyes, and his bright red eyes made the Nine-Tails' hair stand on end.

"Sharingan, Sharingan. How come you have Sharingan? You are not from the Uchiha clan, why do you have these evil eyes?"

Naruto raised the corners of his mouth slightly, revealing a mysterious smile, and said: "Nine-Tails, this is not what you should worry about. At this moment, you should think about whether you are willing to cooperate with me."

The Nine-Tails glared at him and shouted, "Humph, even if you have the Sharingan, what can you do? Don't think you can threaten me like this!"

The three magatama in Naruto's eyes spun rapidly, and powerful pupil power spread out: "Nine-Tails, I don't want to be your enemy, but if you insist on not helping me, don't blame me for being merciless."

Kyuubi felt the extremely oppressive force and was shocked, but he still roared stubbornly: "Little devil, don't be arrogant!"

Naruto said slowly, "I have been through countless pains and sufferings, and these eyes are the witness. Kyuubi, I firmly believe that we can accomplish each other."

Kyuubi was silent for a moment, and then said: "Let me see your determination and strength. If you can convince me, I may consider it."

Naruto took a deep breath, and the three magatama in his eyes began to spin rapidly.

Soon, the Nine-Tails was deeply immersed in the powerful ability of the Sharingan.

In the illusion: Nine-Tails witnessed a series of major events that will happen in the future ninja world, including Uchiha Madara's conspiracy, the appearance of Kaguya Otsutsuki, and the mysterious Otsutsuki clan. Especially the scene where the tailed beasts were recovered one by one, which made Nine-Tails furious.

About half a quarter of an hour later, the Nine-Tails finally recovered from the influence of the Sharingan's power.

But at this moment, the Nine-Tailed Fox was silent, and the entire sealed space was terrifyingly quiet. Only the occasional sound of dripping water was particularly clear in this silence.

Once Kyuubi had digested all the information, a violent aura surged out from the seal.

"Uzumaki Naruto, is everything that happened true?" Nine-Tails asked with a roar.

"Kurouma, you and I are one. I believe you can sense some of the power in me. I am only 4 years old now. Do you think there is any need for me to lie to you?" Naruto replied in a low voice.

The Nine-Tails' eyes were filled with anger and vigilance. It stared at Naruto and said, "Even if all this is true, what can you do? You little brat are still so weak now."

Naruto chuckled and said firmly: "That's why, Kurama, I need your strength. Together we can deal with future crises."

Kyuubi snorted coldly: "You want my power? That's not that easy, you have to prove that you are qualified first!"

Naruto's eyes narrowed: "Kurouma, my power may not be strong enough now. I came to you this time not to ask you to help me wholeheartedly. I just want to borrow some chakra from you." After saying that, the momentum of the 5th level of Qi training suddenly burst out.

The Nine-Tails widened its eyes, looking at the little Naruto in front of him bursting out with such momentum, and couldn't help but feel a little surprised, "Kage level, definitely reached Kage level, really scary, what's more scary is that he is only 4 years old. What a scary monster," the Nine-Tails thought to himself.

But he still said firmly: "Humph, you want to borrow my chakra?"

Naruto didn't mind at all and said loudly: "Kurama, I know you still have doubts about my strength, but with your chakra, I will be able to grow faster and play a greater role in future crises."

Kyuubi pondered for a moment and said in a cold voice: "It's not impossible to lend you chakra, but if you can't control it and are swallowed by this power, don't blame me!"

Naruto showed a determined smile on his face: "Don't worry, Kurama, I can definitely control it!"

The Nine-Tails snorted, and then a powerful chakra surged out of the seal and rushed towards Naruto. Naruto only felt a force inserted into his body. After all, he had reached the fifth level of Qi training, so it was very easy to control this influx of chakra.

When Naruto finally absorbed and stored the chakra, he smiled knowingly and said, "Thank you, Kurama."
