The Ultimate Rat In The World of Ninjas!

In the evening, Naruto moved the table to a corner, secretly avoiding Anbu's surveillance, finished a cup of instant noodles, a grilled fish, and a fresh apple contentedly, and then laid down on the bed.

The apple still maintained its original appearance, with a slight dent on one side.

The items stored in Rat Treasure would remain the same as is at the moment they were put in, so there was no need to worry about the fruit going bad.

As for the grilled fish, it was grilled on the second night after meeting the Third Hokage. Now Naruto basically either went fishing during the day, picked mushrooms, or simply slept at home.

There was no other entertainment, and he didn't want to go to the main street to get stared at.

"Didn't I just get the Chakra refining technique? Let's give it a try!"

Just as Naruto sat up, he stopped.

"It doesn't seem right. Although I can't perceive Anbu's position for the time being, the feeling proves that they have been staring at me. It's not good to be so direct. I should go to the bathroom."

Naruto knew that before he entered the ninja school, he would not be free. He would always be watched by Anbu who hid in the dark, and they would not leave until he was under the school teacher's supervision.

Naruto went to the bathroom, only here was the safest and most shielding place, after all, no matter how bored Anbus were, they would never peep at a kid taking a bath unless Naruto stayed too long, then they needed to pay attention.

Naruto sat cross-legged on the floor while filling the bathtub.

"System, extract the Chakra refining technique."

Because there was no need for this Chakra refining technique to continue to be stored, Naruto directly extracted it. Of course, as long as it was ninjutsu that Naruto knew, it would be detected by the Rat System in the form of data.

[Extracted.]

Immediately, the knowledge and methods on how to use Chakra appeared in Naruto's mind.

And it was the kind of direct comprehension that could be used at any time. It did not need to be learned slowly like reading a book.

Chakra was an energy produced by the fusion of spiritual energy and physical energy. It was the source of energy for performing ninjutsu, genjutsu, and taijutsu.

And this kind of energy was roughly composed of 1. The body's energy was absorbed one by one from the cells in the human body. 2. The spiritual energy exercised through many practices and accumulated experiences.

And Naruto, mental energy was second only to physical fitness, as high as 9 points.

Moreover, children practiced Chakra at the earliest age of 4, and now Naruto was 5 years old. In addition to the unique physique of the Uzumaki family, the successful extraction of Chakra was a matter of course.

Personal attributes:

Chakra: 10+10

...

"You're finally here, kid!"

In an extremely dark and eerie space, a pair of blood-red vertical pupils appeared out of thin air.

Those blood-red eyes were full of hatred, disgust, violence, and cruelty. It seemed that all negative emotions had been gathered in those eyes, and they were watching through the thick darkness, a kid who was sitting cross-legged under the light. Naruto.

[Nine Tails Chakra 0.1% detected, do you want to save it?]

"???"

Naruto opened his eyes in surprise, why did Nine Tails chakra appear?

[Nine Tails Chakra 0.2% detected, do you want to save it?]

"Don't tell me the Nine-Tails is secretly infiltrating his Chakra out of the seal, trying to influence me?"

"Could it be that I didn't detect it before because my Chakra was too little, even Nine Tails couldn't use it to affect me, but now that I actively extracted Chakra, the amount has increased, and the effect has been reflected?"

[Nine Tails Chakra 0.3% detected, do you want to save it? ]

"Save it! System, no matter how much Chakra comes from Nine Tails next time, you can save it directly!"

[Saved 0.3% of Nine Tails Chakra, you can get 100 times the return after ten days, you can withdraw it at any time in the middle, but the reward will disappear. ]

Naruto remembered that in the anime, his Clone Technique could not always be used well because Chakra from Nine Tails interfered.

As for why multiple Shadow Clone Technique was able to work, it was because Naruto had too much Chakra, and the interference of Nine Tails would not work. Instead, it was the previous fine control and Chakra control that was the most difficult.

"Now, no matter how much Chakra you have, Nine Tails, I will keep it!"

The corners of Naruto's mouth curled up, this was the second surprise of the day, and they were all closely related.

Without the Chakra refining technique, there would be no connection to Nine Tails, and Nine Tails would not think about infiltrating the seal. In the end, they would silently work for Naruto.

"Brat, you are just waiting to be... huh?"

Kurama, who was trying to penetrate the seal, suddenly felt something was wrong.

According to the Chakra amount of that kid, the gap in the seal should have been filled by the Chakra he sent out, right?

"Why does it feel like... disappearing, like a stone sinking into the sea?"

Kurama continued to increase the amount of Chakra unbelievingly, 

[0.5% of Nine Tails Chakra has been detected and has been directly deposited into the Rat treasure. ]

[Nine Tails Chakra 0.7% detected, has been directly deposited into the Rat treasure. ]

[Nine Tails Chakra 1% detected, has been directly deposited into the Rat treasure. ]

...

"What did you do to me brat?!"

After reacting, Kurama was instantly furious. Feeling that he was being deceived, it was swinging its nine big tails in the sealed space furiously. If it wasn't because Naruto didn't come in now, Naruto would have been sprayed severely by Kurama.
