Chapter 1 Zhang Shan
"Hey! Good morning, Zhang Shan!"

On the streets of Konoha, a yellow-haired boy and a red-haired girl were walking side by side. At this time, the yellow-haired boy was greeting a black-haired boy not far from them.

The three of them were of similar age and were graduates of the same ninja school. They were all Genin who graduated from the school this year.

"It's Minato and Kushina, are you two out on a date again?" Turning around, Zhang Shan teased the two familiar people.

Being teased by an acquaintance, the thin-skinned Kushina blushed immediately and stumbled to make excuses: "Who! Who is dating this guy? We just happened to meet after we went out!"

Seeing this, Zhang Shan just smiled, without exposing Kushina, and asked the two with a smile: "Don't you have any mission today?"

Minato nodded, his tone slightly helpless: "Well, Jiraiya-sensei has been sent to the front line. For a long time to come, our team will exist in name only."

Although he was only ten years old, Minato was a precocious guy. He knew in his heart that once the war started, it would be difficult to end. At least, it would be difficult to end within a few years!

Therefore, he never thought about asking Jiraiya to teach him. If he wanted to become stronger, he still had to work hard on his own, and...

Minato set his eyes on his good friend Zhang Shan. The other party's strength was even above his own. He had even developed very powerful ninjutsu. He was also developing other techniques recently. Their power was also very strong, not inferior to the previous Rasengan!
That’s right, my name is Zhang Shan, a time traveler. I came to this world called Naruto a year ago and became a classmate of Minato.

In a year, Zhang Shan, with his adult soul, got along well with Minato and clung to the thigh of the future Fourth Hokage. He also brought Minato and Kushina together in advance. The two are now in love, but Kushina is still shy and unwilling to admit it when faced with other people's inquiries.

By the way, as a time traveler, a golden finger is an indispensable thing. Zhang Shan also has his own golden finger, a mysterious space that can communicate with other worlds.

When he just traveled through here a year ago, Zhang Shan met himself who had traveled through time to the pirate world in that mysterious space. The other party was of noble birth, and when they met, the other party's strength was already very powerful. The two of them simply bumped fists in the space, and the strength of both sides was immediately connected. He not only possessed his own very powerful physique in the pirate world, but also the domineering aura and cultivation memory cultivated by the other party!
After leaving the space, his strength increased greatly and he directly reached the level of a ninja in the Naruto world. Moreover, because his physical strength increased, his chakra also became much more abundant. His current chakra amount is about three times that of Minato!
Don't think that Minato has very little chakra. For someone who can become a Hokage, chakra is definitely not a shortcoming! In this case, Zhang Shan's chakra is three times that of Minato. You can imagine how terrifying Zhang Shan's chakra is now. He can easily use ninjutsu such as Rasengan!

Speaking of which, when he was trying to develop Chidori a few weeks ago, he showed the Rasengan in front of Minato. The other party took a liking to this move at first sight and learned it from Zhang Shan. I wonder how he is practicing it now?

However, at that time, Zhang Shan only told Minato the training methods for the first and second stages. If Minato had mastered them, he could start the third stage.

"Hehe! Zhang Shan, come to training ground No. 7 in the afternoon!" Minato winked at Zhang Shan in front of him, his tone full of joy.

Zhang Shan immediately understood what the other party was planning to do, but he did not refuse. He nodded and agreed to Minato's invitation.

After that, the two separated, Minato and Kushina continued their date, and Zhang Shan had his own things to do.

In the past two days, in addition to practicing, Zhang Shan has also been thinking about his next path.

It has been a while since Zhang Shan graduated from the Ninja School, and he has come to understand that his teammates are all just fillers. Such teammates may give up on becoming ninjas and go home to farm after experiencing a battle.

Therefore, the teammates are unreliable. Although the team leader is a jonin, according to Zhang Shan's perception with domineering, the other party is just an ordinary jonin, and his strength is not as good as Zhang Shan himself.

What I can teach Zhang Shan is just some experience. The rest is of no help to Zhang Shan. "I haven't appeared in the Pirate World for a long time. I wonder what's going on over there?"

Since their brief encounter a year ago, Zhang Shan has never seen his self in the Pirate World again. He is a little worried that his self over there is dead...

Because everyone's time of travel is different, although they are the same person at the beginning, they will definitely be affected by the surrounding environment over time, and after a long time, they will definitely be different from the beginning.

For example, the ninja Zhang Shan has only traveled through time not long ago and is still very cautious, while the pirate Zhang Shan has traveled through time for several years and has long lost his initial vigilance. Instead, he has become somewhat careless as his strength has grown.

He returned to his cabin and sorted out his things in an orderly manner. After having lunch, he got up and went to the place where he had an appointment with Minato.

When he arrived, he already saw Minato.

"Minato!" With a light laugh, Zhang Shan jumped to Minato's side and asked, "Have you finished your training?"

"After two weeks of practice, I have finally completed the training of this move!"

Looking at the delighted Shuimen, Zhang Shan made way and pointed at the wooden stake behind him and said, "Hit the stake to test its power!"

Without hesitation, a ball of violent blue chakra instantly appeared in Minato's palm, and he pressed the ball in his hand directly onto the wooden stake!
boom

With a loud bang, the wooden stake in front of him was directly hit by the high-speed rotating chakra, leaving a vortex-shaped crack. Seeing this, Minato nodded with satisfaction and looked at Zhang Shan, waiting for his evaluation.

"Yes, this is considered the completion of the second stage of training of the Rasengan." Zhang Shan nodded. Under Minato's puzzled gaze, Zhang Shan also gathered a Rasengan in his hand and gently pressed it towards the wooden stake!

Boom boom boom

When the blue sphere in Zhang Shan's palm touched the wooden stake, it did not explode and disappear like Minato's Rasengan. Instead, it was like a meat grinder, completely crushing the part of the wooden stake it touched into sawdust that scattered on the ground!
Even until the Rasengan in Zhang Shan's hand pierced through the wooden stake in front of him, the Rasengan in his hand still did not disappear!
"What?!" Minato was shocked when he saw this. He had previously felt that he and Zhang Shan were practicing different things. Now it seems that they are indeed different things, right? !
"Hariyama! How did you manage to keep the Rasengan from exploding?"

"This is actually not difficult, as long as you keep the chakra in your palm!" Zhang Shan smiled and took out a balloon from his pocket, blew it up, tied it tightly and handed it to Minato: "The last stage of the training of Rasengan officially begins!"

*_*???

Minato looked at Zhang Shan with a question mark on his face, not understanding why the other party gave him another balloon.

"The third stage of cultivation is to maintain the results of the first two stages of cultivation in this small balloon!"
