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

The army's movement was slow, and with the addition of thousands of Sand Ninjas whose chakras were sealed, the already slow speed was even slower. It took them half a month to get back to Konoha.

"How handsome, Lord Orochimaru!"

"I want to have little snakes with you, Lord Orochimaru!"

……

As soon as he entered Konoha, the Konoha villagers who had already gathered here suddenly called out loudly, especially Orochimaru's female fans who were even more crazy, and expressed their desire to have children with Orochimaru.

Hearing these bold courtships, Yusuke looked at Orochimaru with some surprise, and found that Orochimaru was indeed very handsome, especially his gloomy face, which was very attractive to girls. Orochimaru felt a little strange and didn't understand why Yusuke was looking at him, but he didn't want to ask more now, as he had things to do.

"Yusuke, go back and have a good rest! We will probably be heading to the Earth Kingdom battlefield tomorrow, and the situation over there is very dangerous!"

Obviously Orochimaru has already received intelligence from the other three kingdoms, and knows that the two of them will soon be heading to the Earth Kingdom battlefield, so he wants Yusuke to take advantage of this time to have a good rest.

Yusuke also nodded, and disappeared from the team in a flash, leaving Orochimaru alone to report to the Hokage.

He had been eating ration pills and dry food most of the time in the Wind Kingdom for so long, and now he wanted to have a good meal. As soon as he entered the house, he smelled a familiar fragrance. He saw his father Akimichi Kazuki busy in the kitchen wearing an apron, and his mother was carrying various prepared meals to the dining table. A large table was already full.

"" Xiongsuke!"

Seeing Xiongsuke, the mother put down the food, stepped aside, and hugged Xiongsuke tightly in her arms. After hugging for a while, the mother let Xiongsuke go, and then looked him up and down, and asked while looking at him:"Xiongsuke, are you hurt anywhere?!"

"Let mom see if you have lost weight!"

"……！"

Hearing his mother's caring words, Yusuke's heart warmed up and he said with a smile:"Mom, with your son's ability, how could he be in trouble?!"

"I'm glad you're okay!"

"I'm hungry!"

……

After having a nice meal with his parents, the family sat on the sofa and listened to Yusuke telling about the battlefield in the Kingdom of Wind. Even though Yusuke deliberately ignored many details, the two could still hear the danger. After chatting, Yusuke returned to his room and took out a notebook from the sealed wristband, recording his feelings about cultivation during this period. Yusuke

's cultivation started from scratch, and he explored every step by himself. He didn't know what the road ahead would be, so every feeling in the cultivation was very important, and even a detour. The cultivation methods in various novels in his mind were just theories for Yusuke, and most of them were useless. Only a few of them could provide him with some useful ideas.

Using this idea and combining it with certain scientific theories, he successfully created the chakra version of the Six-Story Immortal Thief representing the digestive system.

The success of the Six-Story Immortal Thief theory gave Yusuke great confidence, so he has been creating new cultivation methods later, and also set his sights on the motor system and respiratory system, which are one of the eight systems of the human body, along with the Six-Story Immortal Thief.

The reason for choosing the motor system is very simple. First, there are many ninjutsu in the ninja world that involve this aspect, especially the Yang escape represented by medical ninjutsu and Akimichi secret technique, which is the representative of the flesh.

Second, the organs that make up the motor system are relatively less dangerous. Whether it is bone, joint or muscle damage, it can be quickly restored through medical ninjutsu, and there is no fear of repeated attempts.

The last point is that his cheap teacher Orochimaru has a lot of human experimental data, which makes him very familiar with the human body.

Now he has succeeded in most of the exercises in the motor system. He has completed the bones and muscles of his limbs. This is also the reason why he can easily hit ten tons of power on the battlefield this time, and with the instant burst of chakra, he can knock away Shukaku, which weighs eight thousand tons.

The rest is the spine and skull, and what he is writing at this time is the speculation about the practice of the big dragon of the spine.

As for the respiratory system, it is because of the fairy technique. The breathing method is the main reason for maintaining the fairy technique time. The general fairy mode cannot last too long, and Jiraiya can only last for five minutes.

The reason why Yusuke can always maintain the Sage Mode is that he has converted all the chakra in the Qi Sea Seal into Senjutsu Chakra, so as long as the Qi Sea Seal is not consumed, his Sage Mode will not exit.

However, this will eventually lead to exhaustion, so being able to use breathing techniques to create a breath-eating technique is Yusuke's top priority.

After being taught by the White Snake, Fukasaku, and Shima, he also has his own ideas about creating a perfect breathing system and a breathing method based on the Myoboku Mountain breathing method.

"In the cultivation concepts of various novels in the past life, whether it is the various systems of qi and blood, true qi or magic power, the spine is regarded as a bridge connecting heaven and earth.

These concepts are likely to be borrowed by the author from the Taoist theory.

I have also seen these theories in many film and television works and novels.

The main thing is to open up three important roads - the coccyx point, the Jiaji point to the Yuzhen point, so that the essence, qi and spirit will be connected, completing the gathering of the three flowers and reaching the legendary innate state.

"

"But chakra is completely different from true qi and mana. It flows freely between the meridians and acupoints without any blockage. But I also don’t have the feeling of the essence, energy and spirit flowing through. So the so-called opening of meridians and acupoints by true qi is not due to blockage. It should be said that it is not because of impurities in the human body that these places are blocked."

"Maybe I should go find Might Guy and learn how to break through the eight gates of the Eight Gates!"

Thinking back on the practice during this period, Yusuke also understood the difficulty of creating his own skills from scratch. He had learned about the meridians and acupoints, otherwise it would be impossible to complete the Qi Sea seal with acupoints.

Now all he can do is to use the fairy chakra to temper the spine and skull as carefully as he exercises his limbs.

After recording the insights of his practice, Yusuke sat cross-legged on the bed, using meditation to concentrate his attention, and very carefully used the fairy chakra to temper the spine bit by bit.

There are a total of twenty-four vertebrae, and now Yusuke is tempering the last coccyx, which has the least impact on the human body when there is a problem with the coccyx.

With the experience of practicing the limbs, Yusuke successfully completed the practice of two vertebrae in just one night.

In the morning!

Yusuke came to the family's training ground and began to practice boxing to stretch his muscles. After a set of boxing that combined various physical techniques and soft fists,

"It is worthy of being called the bridge between heaven and earth. After only two sections were successfully opened, my explosive power increased by about 20%. This is the tail vertebra at the end, which is basically not used for exerting force. If all of it is opened, how powerful will my power be?"
