Naruto started cultivating immortality from creating the Six-fold Immortal Thief

Yusuke's strength is now infinitely close to that of Uchiha Madara and Senju Hashirama at their peak, especially after completing the motor system, respiratory system and cardiovascular system. His physical strength is several times stronger than the two, and his recovery ability is comparable to that of Hashirama's sage body. It's just that his chakra amount and the nature of chakra changes are still far behind the two, so his strength is not as good as the two at their peak.

Feeling Yusuke's strength, Minato's heart, which had been hanging in the air, relaxed, and said with a smile:"Since you already have an idea, then do it according to your idea. If you need anything, remember to come to me and Kushina, the two of us will definitely help you."

Kushina nodded repeatedly:"Yeah! Yeah!" Yusuke felt warm in his heart, and smiled:"If you need anything, we will definitely help you."~！"

After that, he took out two scrolls from his wristband, the improved"Sage Body" and the"Reverse Life Triple" created by Orochimaru, and placed them in the hands of the two men.

"Brother Minato, sister! This is the subsequent training method that my teacher and I have perfected. You two can practice it when you have time. It should help you improve your strength."The current Namikaze Minato has completed the training of the Sage Mode using some of Yusuke's theories, and has accumulated a lot of Sage Chakra in his body, which is much stronger than the same period in the original work.

Although Kushina does not know Sage Techniques, she has the Nine-Tailed Fox, an oversized power bank, in her body, and her strength is still above that of Namikaze Minato.

However, Yusuke can also see that the strength of the two has reached a bottleneck. If they want to increase their strength again, they can only let time settle, or Kushina can completely master the power of the Nine-Tailed Fox.

That's why Yusuke taught these two training methods to the two.

Minato and Kushina glanced at the scroll briefly, stuffed it back, and said in unison:"Yusuke, we can't take this. I can see that this is the crystallization of your and Lord Orochimaru's wisdom. It must have taken a lot of time and energy. You should give it to your people."

Yusuke stuffed the scroll into the arms of the two again:"I have already given it to my parents. As for the tribe members, I don't plan to give it to them for the time being. The three tribes of Ino, Deer and Chou are still very loyal to the Sarutobi tribe. I am worried that if I give them the training method, it will soon appear in Sarutobi Hiruzen's place. This is something I don't want to happen.

So it's best to give the skills to you two, Minato brother.""

"But……"

"Brother Minato, actually I have selfish motives in giving you the skills. You also know that these skills are all my ideas, which I have explored like crossing a river by feeling the stones. Every step forward is full of difficulties.

I also want you to help me with experiments and provide me with new ideas!"

Yusuke was right about this. As his strength grew, he found it difficult to innovate new skills. The method of practice is not just about having ideas, but also requires a lot of theoretical foundation and practice.

The initial practice was okay, and the theoretical foundation required was not much. It was not enough to rely on Orochimaru's large number of experiments.

Therefore, the more people who practice in the future, the better. Only in this way can we pool our wisdom and embark on the road of evolution together.

Of course, Yusuke also kept a trick up his sleeve. The method of practicing the immortal body that he handed over was only to condense the immortal body, and did not create the perfect eight systems. Even Orochimaru did not know the most important knowledge of the acupoints.

"Okay, then we'll take it." The Minato couple understood Yusuke's good intentions and accepted the scroll.

"In addition, there is one more thing."Yusuke looked at the two of them with a serious expression,"Regarding the Nine-Tails, I hope you can master its power as soon as possible.

Kushina asked puzzledly:"Why do you say that?" Yusuke said solemnly:"Because Uchiha Madara, I always feel that he is planning something behind the scenes?! You know, this senior has been secretly planning for decades, and no one knows what kind of earth-shattering event he is going to do.……"

Yusuke has always been in awe of Madara, and is also preparing to deal with Madara's infinite moon reading plan in the future. Because of this variable, he is not at ease to leave the fate to the future Naruto and Sasuke.

Not only Madara, but Black Zetsu is a greater threat. As an old monster who has lived for a thousand years, even if his power is insufficient, his experience, knowledge, insight and wisdom are not comparable to Yusuke. What's more, there is the threat of the Otsutsuki clan, so the more powerful people in the future ninja world, the better. This is the only way to deal with future crises.

A trace of worry flashed in Minato's eyes:"You mean, the enemy will be very powerful?"

Yusuke nodded:"Yes, and the enemies in the future may be beyond our imagination. So we must be fully prepared."

Minato took a deep breath:"I understand. Kushina, we will start to practice hard after we go back."

Yusuke looked at the two of them, full of confidence.

But the first thing to do is to deal with Sarutobi Hiruzen, who is good at internal wars but not external wars.

Thinking of this, Yusuke did not disturb Minato and Kushina's world of two people. Except for the Senju clan, he walked towards the Uchiha clan opposite.

The current Uchiha clan has not moved away from the core area of Konoha as in the original work. Their land is just opposite the Senju clan. That is why Kushina and Mikoto often visit each other and become best friends.
