Reborn Naruto: Starting with its own system

Soon, Naruto saw everyone's expressions and waved to Itachi, signaling him to stop. Naruto's goal had been achieved, and there was no point in continuing the fight. Moreover, Naruto still had a stronger strength.

Naruto came in front of all the friends, looked at them and said, "How do you feel?" Everyone looked at each other, but no one spoke. It was as if the one standing in front of them was no longer the familiar Naruto. They were all deeply immersed in the powerful strength displayed by Naruto, and could not extricate themselves for a long time.

Seeing that everyone was silent, Naruto then said: "My strength has just been fought against Brother Itachi, I believe everyone has understood it. Then I will ask you again, do you want to learn powerful skills from me?"

Sasuke was the first to respond, his eyes determined as he said, "Naruto, I want to learn!"

Shikamaru stopped being lazy and said seriously, "Count me in."

Choji swallowed and said loudly: "Naruto, I want to learn too!"

Ino nodded along, "I don't want to fall behind."

Ya clenched his fists: "Of course I have to learn!"

Shino pushed up his glasses and said, "I'll join."

Hinata blushed and said quietly but firmly, "Naruto-kun, I do, too."

Naruto smiled knowingly, and then began to teach the "shaving" training method.

"Everyone, listen carefully! The key to the 'Shave' skill lies in the precise control of the instantaneous explosive power of the leg muscles." Naruto explained solemnly with a serious expression.

"First, you have to concentrate and deeply feel the strength of your leg muscles. Try to concentrate the strength on your calf area." Naruto explained while personally demonstrating the standard movements.

The little friends all stared intently, not daring to miss any details.

"Then, at the moment of exerting force, it should be like this..." Before Naruto could finish his words, he kicked the ground suddenly, and his figure instantly disappeared from the original place, and then appeared steadily not far away.

"Wow!" Everyone couldn't help but exclaim.

"You must remember to practice continuously. You may fail at first, but never give up easily." Naruto looked at everyone with a firm and encouraging gaze.

Shikamaru scratched his head and said with a bitter smile: "This is really difficult."

Naruto smiled and responded, "Shikamaru, as long as you keep practicing, you will definitely succeed."

After trying several times, Choji was exhausted and panting, and complained: "Naruto, this is too difficult."

Naruto patted his shoulder and comforted him: "Chouji, have faith in yourself, you will definitely be able to achieve it."

Under Naruto's patient guidance and constant encouragement, the friends worked hard and practiced the "shaving" technique with all their might.

Naruto turned to Itachi and said, "Brother Itachi, I will teach you the training method now." After that, he stretched out his finger and pointed at Itachi's forehead. The moment he touched it,

A surging stream of information instantly poured into Itachi's mind like a torrent. Itachi only felt a sharp pain in his head, but he clenched his teeth, endured the discomfort, and concentrated on trying to understand and absorb this information.

At this moment, Itachi was filled with shock and excitement. This was a brand new training system. He never expected that the training method mastered by Naruto was so exquisite and profound, far beyond his imagination. He knew very well that once this training method was leaked, the ninja world would usher in a brand new earth-shaking change. At the same time, he was sincerely happy that Naruto could teach him without reservation. But he was also deeply puzzled by Naruto's mystery, wondering how Naruto got such a magical training method.

After a long while, Itachi slowly opened his eyes, a look of understanding in his eyes.

"Naruto, thank you." Itachi said sincerely.

Naruto smiled and waved his hand, saying: "Brother Itachi, there is no need for us to be so polite. If you have any questions, feel free to come to me."

At this moment, Itachi was deeply impressed by Naruto, who had such talent at the age of 6. Then he bowed deeply to Naruto and said, "Naruto, I will always remember this friendship."

Naruto quickly helped Itachi up and said, "Brother Itachi, don't be so polite, let's make progress together!"

When the friends around heard their conversation, they looked at Naruto with a little more admiration and envy.

Itachi stood up straight and looked at Naruto with a firm gaze, as if he secretly swore in his heart that he must cherish the precious friendship given by Naruto and live up to Naruto's trust and expectations of him.

Day after day, month after month, the group of friends made rapid progress under Naruto's guidance. They have completely mastered the Marine 6 Styles.

Shikamaru's "Shave" is as fast as the wind, and his movements are unpredictable; Choji's "Iron Block" is extremely hard, like an unshakable hill; Kiba's "Paper Painting" is light and agile, like a dancing butterfly when dodging attacks; Sasuke's "Finger Gun" is sharp and swift, and each blow contains great power; Hinata's "Moon Step" is elegant and agile, and her figure is light when moving in the air; Ino's "Storm Kick" is powerful, and the wind blades it kicks out are incredibly powerful; Shino's "Paper Painting" is skillfully used, and he can always avoid attacks just right.

They competed with each other on the training ground and showed strengths that were completely different from before. The powerful skills that were once out of their reach were now able to be used freely.

In terms of cultivation, everyone's progress was extremely slow. After many hardships, several people barely reached the 5th level of Qi Naking. Even Itachi, who was the most talented, only reached the 7th level of Qi Naking. Naruto often patiently explained the key methods and problems to everyone, and sometimes even took out precious enlightenment pills for everyone to take, but the effect was still not very obvious.

In fact, Naruto knew very well that the biggest reason was that the spiritual energy in the air of the ninja world was extremely thin, which resulted in the extremely limited chakra they could produce. Unlike himself, as a descendant of the Uzumaki clan, they were born with a huge amount of chakra, and they also had the Nine-Tails in their bodies, which could be called a super charger. The most important thing was that Naruto also had a natural body. This series of unique conditions made him smooth sailing on the road of cultivation, while his friends were not so lucky.

Naruto sighed helplessly. He could provide support and help in other aspects, but he was helpless in terms of spiritual energy. It seemed that this matter could only be considered in the long run. However, Naruto was quite satisfied with the progress of everyone's strength. They already had the strength to compete with the jonin. Moreover, everyone was still young, and there were more unlimited possibilities in the future.
