Masahiko stayed in Konoha for about half a month, and got 10 witness points each from the proposal of "Hero Saves Beauty" and Tsunade's medical ninja to join the team, which can be regarded as a full return.

Before leaving, he also sent Tsunade to the Wet Bone Forest, and learned from the Slug Immortal that Tsunade had the conditions to cultivate into the Immortal Mode, which made him even happier.

"Speaking of which, maybe Tsunade will be stronger than Jiraiya in the future?"

As for Orochimaru, Masahiko didn't make a comparison, and he didn't know in his heart which part of Orochimaru's strength should belong to.

"Survivability SSS, I can't afford to mess with it."

Rope Tree really followed Masahiko back to the country of Vortex, and it seems that competing with Fugaku for Uchiha Mikoto has become the biggest motivation for his cultivation.

Masahiko glanced at him with a smile, "Rope tree, you're 15 years old, Mikoto is also 14 years old, and she's going to get married later." ”

Rope Tree shook his head, "No, Mikoto said that she would wait for me to defeat Uchiha Fugaku!" ”

Masahiko's face froze, and he muttered: "What is the situation, it turned into a rope tree to rescue the captured princess Mikoto from the hands of the great demon king Fuyue?" ”

Shaking his head, he didn't believe it in his heart.

"I guess it's the kind Mai Trin encouraging him, right?"

Returning to the whirlpool, Masahiko did not look for Nagato in the first place, in his heart, there was one more important thing.

"Yuna, how's the kunai cutting machine being studied?" When Masahiko pushed the door in, Yuna was still busy.

Seeing Masahiko, she was stunned for a moment, and then looked at another Masahiko on the side.

"Grandpa Masahiko, you actually fooled me with a shadow clone!" Yuna's shouts came.

Masahiko's face froze, and he smiled wryly, then frowned.

He fully accepted the message sent back by the shadow clone, and sighed, "Did you fail?" ”

Yuna shook her head, "It's not a failure, Grandpa Masahiko." The accuracy can't be improved, we can let the ninja manipulate it, as long as there is a chakra control ability of the middle ninja, there will generally be no mistakes. ”

Masahiko nodded, but there was still some pity in his heart. In this world where chakra is the mainstream, in the end, there is still no way to develop a device that does not require chakra at all, although it can also be mass-produced kunai, but civilians are completely unable to participate.

Although Masahiko had forgotten all about economic development measures, he still knew that the country could only be strong if the common people had a stable economic source, so he proposed to build such a machine, but he didn't expect it to fail in the end.

Yuna saw that Masahiko was a little lost, and shook her head with a smile, "Grandpa Masahiko, it's not that there is no way at all, I can try again." ”

Masahiko nodded, "There shouldn't be anything I can help with after that, so I'll leave it to Nagato." ”

Yuna was stunned for a moment, and showed a smile, "Nagato is also five and a half years old, and it is indeed time to start practicing." ”

Masahiko waved his hand and turned to walk towards Iko, Yuna and his husband were busy during this time, and Nagato spent most of his time at Iko's.

Sure enough, when he came to the patriarch's hall, Xiao Nagato was sitting on the side, watching Yizi busy.

"Teacher, are you back?"

Masahiko nodded and smiled.

"When I come back, Nagato will become your little junior brother."

Yizi was stunned for a moment, "Teacher, do you actually want to officially accept him as a disciple?" ”

Over the years, Masahiko has taught many people, Sarutobi Sasuke, Shimura Ken, Kushina, Rope Tree, Hinata Brothers...... But Masahiko has always recognized the only disciples in his heart as the three of them, but now, Nagato is going to be added.

Masahiko nodded and looked at Xiao Nagato, who was still ignorant, "This kid's talent is very good, I'm ready to accept the fourth disciple." ”

For some reason, Yizi's face suddenly turned strange.

"You...... You won't teach Nagato to be like Hitomi, will you? ”

Masahiko was stunned, unable to cry or laugh.

Indeed, of the three disciples accepted, two girls are fine, one majoring in sealing and the other majoring in ninjutsu. However, the male disciple who majored in physical arts is really a black history.

"Don't worry, although the three of you have good talents, you can only refine the same. But Nagato is different, and he may have the hope of inheriting all of my ninjutsu, body arts, and sealing techniques. ”

Yizi still hesitated, "Ninjutsu and sealing should be enough......"

Masahiko glared, "How can a ninja have shortcomings." Just like you now, although your strength is not bad, you have never been able to become one of the top people in the ninja world......"

Masahiko began his disciple education.

After a long time, Masahiko stopped, said a few words to Konagato, and led him to the next door.

The first step in the initiation of ninjas, in addition to the history of the ninja world and the like, is to refine the chakra. And the history of the ninja world or something, in Masahiko's opinion, it really doesn't matter much, now he, he can be ashamed to say, he is the history of the ninja world!

Therefore, Masahiko is going to promote his own glorious history on the way to teach Nagato......

In short, the first step in Nagato's ninja enlightenment is chakra refining.

The so-called chakra refining method, Masahiko really has nothing special, or rather, the whole ninja world is such a fixed set.

Nagato's talent is indeed high, and the same method of refining chakra was successful in about ten minutes.

As for what level ten minutes is, you can see by looking at Masahiko's red old face that he was called the genius of the Uzumaki clan in ten hours......

There is no need for any chakra test paper, Masahiko Kagura's heart eye can be perceived as soon as Nagato's chakra attribute is opened, and after his yin attribute reaches the ninth level, Kagura's ability to heart eye has also been improved.

"Wind, earth, fire? That's a coincidence! "Masahiko is secretly happy, although Nagato, who has no eye of reincarnation, is not born with all five attributes, but it is just right, and the three attributes are the same as when Masahiko was young.

"In this way, it would be best to improve him according to the cultivation method I used when I was a child!" Masahiko muttered, "And born with wind, earth, and fire, there is hope for cultivating into the dust......"

After thinking about it, Masahiko sighed again, "I can only hope that he has talent." ”

Masahiko's cultivation is completely the credit of the system, he can only describe it in general, and he doesn't know how to teach others at all. Therefore, Yizi has not cultivated to the dust until now.

"From today onwards, I will officially teach you ninjutsu and accept you as your fourth disciple!" Masahiko looked at Konagato and said with a smile.

"Hmm!" Konagato was a little introverted and only agreed.

Masahiko was stunned, and a line of Chinese characters crossed in front of his eyes, "Witness and completely change the side plot of the Hokage World: Nagato's teacher, get 10 (*10) witness points." ”

"Is that okay?" Masahiko was overjoyed, "In this way, maybe I'm going to take in a fifth or even sixth disciple......"
