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

With the Water Transformation Technique and the existence of the Manzuki, Orochimaru's three-fold reverse birth went very smoothly. He soon had his own ideas and had simply perfected the existence of the second level.

But Yusuke encountered setbacks. After Orochimaru handed him the Eight Gates of Dunjia, he began to study the acupoints and meridians based on the theory of the Eight Gates of Dunjia. The initial research was very smooth, and Yusuke really figured out something.

That is, the meridians themselves are unobstructed, and there are no problems with the acupoints themselves.

In the past, the so-called opening of the meridians by Taoism and Chinese medicine was to connect the acupoints one by one, using the meridians as a medium to form various systems, thereby affecting the internal system of the body, making people free from disease and disaster, and exerting power far beyond the limit.

However, the problem facing Yusuke at this moment is how to connect the meridians. The method of connecting the acupoints of the Eight Gates of Dunjia is too rough and simple. It can be said that it is to use external force to forcibly break through the acupoints, and then under the action of the body's self-protection mechanism, the opened acupoints will automatically close again.

Although this method can burst out powerful power in a short period of time, the damage caused to the body should not be underestimated.

There is no doubt that opening and closing these eight acupoints for a long time can gradually connect these acupoints. And this is why Kai was able to open the Jingmen directly. Since the previous seven acupoints are already connected to each other unobstructed, he can transfer power to the Jingmen in an instant and achieve such an amazing breakthrough.

However, for Xiongsuke, this method is not a good strategy.

What he pursues is a steady method-by opening the acupoints smoothly, so that they always remain unobstructed.

Compared with the rough method of breaking the acupoints such as the Eight Gates, Xiongsuke prefers a gentle and lasting method.

If it were not for the strong recovery ability of chakra and the human body itself, those acupoints that were forcibly broken would probably have been useless long ago.

Because of this, opening the eight gates will have extremely high requirements for physical fitness.

After all, only people with a strong physique can withstand this huge pressure and benefit greatly from it.

But fortunately, the Eight Gates also provided Xiongsuke with ideas and methods.

But after many experiments, he still failed. He even asked Orochimaru for some test subjects and clones, but in the end, he still felt that he was just one step away from finding the acupoint.

"It seems that I must feel the state of the acupoints being opened to verify my guess!"

"Open the door!"

""Open the eight gates!"

The two gates opened instantly, and Yusuke's chakra began to be consumed rapidly, running through the meridians at an unimaginable speed, making Yusuke feel a trace of pain for the first time in a long time.

He closed his eyes silently, and completely immersed his mind into his body, feeling the state of the two acupoints in his brain, concentrating his energy, trying to guide the flow of chakra, and looking for that tiny breakthrough.

He slowly adjusted his breathing, calmed his heart, and maintained this state.

Compared with people like Might Dai, Kai, and Xiao Li, Yusuke's chakra is like the Yangtze River. After opening the eight gates, the burden on the body is dozens of times theirs, and of course the endurance is dozens of times theirs.

So Yusuke can feel the mystery after the eight gates are opened by maintaining this state for a long time.

As time passed, fine beads of sweat oozed from Yusuke's forehead, and his face turned pale.

He clenched his teeth and persisted.

""Huh!"

Finally, Yusuke couldn't bear it anymore and closed the two doors. He gasped for breath, his face full of fatigue, but the smile in his eyes could not be hidden.

"The long-term maintenance has given me a sense of something. I believe that if I try a few more times, I will be able to create a way to open the acupoints!"

After a short rest, Yusuke began to try again.

With repeated efforts, his perception of the acupoints in his body became clearer and clearer, and he gradually understood the way to open the acupoints.

After another opening of the Eight Gates, he finally found the tiny breakthrough. With a thought, the originally violent chakra instantly became extremely gentle, flowing like mercury. The originally broken acupoints began to repair under the protection of the body, but they were not completely repaired, leaving a tiny channel for the chakra to flow in the acupoints.

"Success! The next step is to slowly expand these two acupoint channels and completely open up the acupoints!"

Xiongsuke showed excitement. Although this method of opening up the meridians did not increase strength as much as the Eight Gates, it might only be one percent, but it was more stable. Moreover, there were at least 720 acupoints in the human body. He dared not imagine how much power he could gain after all of them were opened up.

Xiongsuke was immersed in joy. He knew that this was just the beginning. The road ahead was still long, and there were countless challenges waiting for him.

He decided to take a good rest first to recover his physical strength and spirit.

During the rest, he also thought about how to better expand the acupoint channels.

"The eight acupoints of the Eight Gates of Dunjia are not suitable for me. The root of my practice is still in the Qi Sea seal in the four acupoints of Dantian, so the beginning of opening up the meridians and acupoints should be from Dantian."

"It just so happens that the expansion of the Qi Sea Seal has been slower and slower in the past two years, and opening up the four orifices of the Dantian should bring me different surprises!"

In the past two years, the improvement of the fairy chakra in the Qi Sea Seal of Yusuke is basically in quality, not quantity. The quantity has increased very little. This is the limitation of the Qi Sea Seal. It should be said that the attainment of the sealing technique is not enough.

With the study of the sealing technique, Yusuke gradually realized the essence of the sealing technique.

The essence of the sealing technique is Yin and Yang escape, but it is different from the traditional Yin and Yang escape. It emphasizes sealing the body and spirit, so the potential of the sealing technique can be said to be the greatest in the entire ninja world.

It is for this reason that Yusuke understands why the ninja world cannot accommodate the Uzumaki clan. If it is allowed to develop like this, it is estimated that the entire ninja world will not be the opponent of the Uzumaki clan.

……

As time went by, Yusuke's efforts gradually paid off. The opening of the four orifices of Dantian was very smooth. He could clearly feel that the chakra was constantly increasing, and the speed of progress was able to catch up with the time when he just obtained the seal of Qi Sea as a child.

However, he was not satisfied with this. He knew that only by continuous exploration and breakthroughs could one truly become a strong man.

This training lasted for two years. During this period, Yusuke and Orochimaru did not receive any tasks and were in a state of no one cared about them. However, this was also something the two were happy to see, as they could seize the time to practice.

In two years, Yusuke had already perfectly built the motor system and respiratory system. The training method was named Immortal Golden Body and Nine Breaths to Subdue Qi, but the progress of the endocrine system was very slow.
