Naruto: Can't learn ninjutsu? I'll just practice immortality!

That's right, the Five Elements Divine Thunder can complete the spiritual roots!

In the early stage of cultivating immortals, when refining essence into qi and refining qi into spirit, the fewer spiritual roots the better, and the speed of cultivation is the best with a single spiritual root, followed by two spiritual roots.

But in the second stage of cultivating immortals, after the perfection of the Qi Refining Spirit Realm, if you want to break through the third stage of Refining Spirit and Returning to Void, you need the fusion of the five elements.

At this stage, only by completing the five elements of spiritual roots can you sense the five elements, and then integrate them and break through the Refining Spirit and Returning to Void.

The method of completing spiritual roots recorded in the Basic Qi Refining Art mainly relies on natural treasures or demon beasts' inner elixir.

Originally, Asakawa Naoki's realm was still low, and he didn't worry about the problem of completing spiritual roots.

But after a few years, with the help of Samadhi True Fire and the Yin Nine-tailed Fox in his body, his cultivation speed is as fast as flying a sword.

Although he is not very old, Asakawa Naoki's cultivation has reached the middle stage of Qi Refining Spirit in the second stage of cultivating immortals.

According to his estimate, within ten years, he should be able to reach the late stage of Qi Refining Spirit, or even perfection.

When he wanted to break through the Refining Spirit Return to Void, the biggest headache for Naoki Asakawa was the method of completing his spiritual roots.

At the beginning, he was going to find some natural treasures of the five elements to complete his spiritual roots.

He gave up this idea until he killed Hanzo and let his avatar become the leader of the Hidden Rain Village.

According to the records of the Hidden Rain Village and the information obtained by the Anbu ninjas of the Hidden Rain Village, there were almost no natural treasures of the five elements in the ninja world.

Then, Naoki Asakawa set his sights on the inner elixir of demon beasts.

But there were no demon beasts in the ninja world, only summoned beasts.

As we all know, summoned beasts have no demon elixir.

So, he finally set his sights on the tailed beasts.

Strictly speaking, the tailed beasts are not even considered creatures, because the tailed beasts are made up of chakra.

Naoki Asakawa's original plan was to erase the consciousness of the tailed beasts, use the fire of air to refine the essence of the tailed beasts, and use the essence of the tailed beasts as the material to complete the spiritual roots.

But then, Asakawa Naoki was a little desperate.

He was a dual-spiritual cultivator. The fire spiritual root was naturally needless to say. The thunder spiritual root was a variant of the wood spiritual root, which was equivalent to him having dual fire and wood spiritual roots. He only needed to complete the three spiritual roots of gold, water and earth.

The water spiritual root was easy to say. The three-tailed Isobu was a tailed beast that mastered water escape. It was quite good to use its origin as a water spiritual root.

The earth spiritual root was also okay. The four-tailed Sun Wukong was a tailed beast that mastered lava escape. Lava escape was a fusion of fire escape and earth escape. If the fire escape part was separated, the origin of the four-tailed Sun Wukong would be used as an earth spiritual root.

But the last gold spiritual root, no tailed beast could have it.

So, Asakawa Naoki had been thinking about taking it one step at a time.

Until he broke through the middle stage of Qi Refining and Spiritualization, he had not thought about how to complete the gold spiritual root.

But now, a better way appeared directly in front of him, how could he not be happy.

In addition to not having a gold spiritual root, using the tailed beast essence to complete the spiritual root has another disadvantage.

The tailed beast comes from the sacred tree and is too closely connected to the Otsutsuki Kaguya clan.

Asakawa Naoki is not afraid of Otsutsuki Kaguya, but he is worried that the tailed beast essence chakra may have some secrets.

Especially after discovering that ninjas with chakra cannot cultivate mana, Asakawa Naoki is still a little wary of Otsutsuki Kaguya, the ancestor of chakra.

Now, with the Five Elements Divine Thunder, a method that only relies on one's own five internal organs to complete the spiritual root, how could Asakawa Naoki consider the inconvenient thing of the tailed beast essence?

There is not much to do recently, so Asakawa Naoki began to practice the Five Elements Divine Thunder.

This method can only complete the spiritual root until it is fully developed, and there is no need to worry about affecting his practice speed.

......

When Asakawa Naoki's body was practicing the Five Elements Divine Thunder, a team of five Rain Hidden Anbu ninjas were searching for something at the border of the Wind Country.

"Minister Yuchuan, is this really the place?" an Anbu ninja asked.

"Could that Hyde be lying to us? There is no vein of Grayer Stone in this broken place." Another Anbu ninja echoed.

"Hyde's memory has been searched by torture ninjutsu, so it can't be wrong." Yuchuan shook his head and said:

"The vein of Grayer Stone should be in this area, keep searching!"

"Got it, Minister Yuchuan!" The remaining four Anbu said in unison.

The endurance of Anbu ninjas far exceeds that of ordinary ninjas. They won't even cry out for torture that ordinary ninjas can't bear.

But after searching this desolate area for a month, nothing was found, and even they couldn't help but complain a few words.

In fact, Yuchuan didn't say anything.

Hyde's memory would not deceive them, but the information Hyde got was not necessarily true.

If Hyde's information was so detailed, the other party would have found Grayer Stone long before their Rain Hidden Anbu arrived.

But now, Yuchuan can't sayOtherwise, the confidence of these Rain Hidden Anbu will be severely hit.

If the people are scattered, it will be difficult to lead the team.

It is okay if the team is difficult to lead. If we cannot complete the task of Master Akiba and fail Master Akiba's expectations, that will be a big deal!

"Yuhe, did you sense any chakra?" Yuchuan looked at a Rain Hidden Anbu.

"Sorry, I didn't feel anything." Yuhe shook his head.

Even the perception ninja in the team could not sense it, so the remaining few people naturally could not sense the location of the Gray Stone vein.

"It's okay, take a rest here, and we will continue later." Yuchuan said.

"Thank you, Minister." Yuhe was about to sit down to restore his chakra, but he sensed something, frowned slightly and said:

"Minister, there is a situation!"

"Sensed the Gray Stone vein?" Yuchuan's eyes flashed with joy.

"No, it seems that the second team has a conflict with the Sand Ninja!" Yuhe reported.

"Got it, get ready for support!" Yuchuan stood up and led the team to the scene of the accident quickly.

Soon, Yuchuan's team found the second team of Anbu besieged by the Sand Ninja team led by two senior ninjas.

In fact, the strength of the Rain Hidden Anbu team is not weak, but the water-scarce country of Wind has too severe a restraint on water escape. The five-member Rain Hidden Anbu team can only barely resist the offensive of the Sand Ninja.

However, after the addition of the Yuchuan team, the field showed a crushing trend.

Although Yuchuan's strength is not at the level of Kage, it still exceeds that of ordinary senior ninjas. One person can deal with the two teams, not to mention the cooperation of other Anbu.

In the end, at the cost of two Anbu ninjas being slightly injured, the two Sand Ninja teams were annihilated.

Although the opponent was completely annihilated, Yuchuan was not happy at all.

Although it is not known what mission the two Sand Ninja teams came to perform, the two teams disappeared here, and it is likely that it will not take long for the Sand Ninja Village to search here.

By then, it will be difficult to find the Greyer Stone vein.

But at this moment, Yuhe showed joy on his face and shouted excitedly:

"Captain Yuchuan, I found it!"
