I will use the ninja world to aid my cultivation of immortality.

True Qi not only surpasses chakra in quality, but it can also completely replace chakra in all aspects of application.

Like the Lightning Release technique used in the previous battle against the Shadow Clone.

Using true qi to unleash lightning release is not only effortless, but its power far surpasses that of lightning release using chakra.

"Techniques cast with true qi can perhaps be distinguished from those cast with chakra. I've got it! Since this is about cultivating immortality, techniques cast with true qi can certainly be called magic, that is, lightning release can be called lightning magic."

Naraku stroked his chin and began to ponder.

The more Naraku thought about defining the techniques that utilize true energy as spells, the better it seemed.

After all, even the immortals in this world can call their techniques "immortal arts," so what's wrong with calling the techniques I use with my true energy "magic arts"?

"Then the next thing to do is test the shadow clone technique."

Having decided on a name, Naraku refocused his attention on the test.

With his hands forming a cross in front of him, Naraku instantly created another shadow clone, accompanied by a cloud of smoke.

However, unlike the shadow clones used in previous tests, this time the shadow clones were created using true qi.

"let's start!"

Naraku looked at the true energy shadow clone he had created and gave instructions to it.

"Understood!" The True Qi Shadow Clone nodded without hesitation and immediately sat cross-legged, adopting the posture of five hearts facing the sky, to begin cultivating the Nameless Technique.

Seeing this, Naraku kept a close eye on the situation of the True Qi Shadow Clone.

While the techniques of ninjas may not reach the highest level of cultivation, they still possess unique advantages at the lower levels.

For example, shadow clones.

As a physical clone, a shadow clone can not only fight in place of the main body, but also feed back its own memories and experiences to the main body after it is deactivated.

The latter can also be applied to cultivation.

Just like Sage Mode, it allows you to absorb natural energy through shadow clones, thereby quickly condensing Sage Chakra.

Naraku's test at this time was to see if the True Qi Shadow Clone Technique could also help to quickly condense True Qi.

As for why it's a true qi shadow clone, instead of an ordinary shadow clone...

This comes down to the issue of spiritual roots.

The path to immortality requires two fundamental foundations.

One is spiritual energy.

Without spiritual energy, one cannot cultivate.

The second is the spiritual root.

The spiritual root is like a transfer station between the human body and spiritual energy. If one lacks a spiritual root, not only will it be difficult to absorb spiritual energy, but it will also be impossible to refine spiritual energy into true energy.

Naraku had previously tested the Shadow Clone Technique, but he eventually discovered that the Shadow Clone Technique created by chakra did not possess spiritual roots. In other words, it could not absorb spiritual energy to refine it into true energy.

So after these days of cultivation, with his true energy becoming much more abundant, he decided to see if his true energy shadow clone had changed.

At this moment, Naraku quickly observed that the surrounding spiritual energy was gradually being drawn into his body by the True Qi Shadow Clone.

"Success!"

Upon discovering that spiritual energy had entered the body of the True Qi Shadow Clone, Naraku was immediately overjoyed.

This is because it means that the True Qi Shadow Clone is different from the Chakra Shadow Clone, and can also apply spiritual roots to the Shadow Clone.

It could be because of the different world they live in, or it could be because they lack the affinity for immortality.

In short, Naraku was originally a person without spiritual roots. Under normal circumstances, even if he obtained the inheritance of immortal cultivation, it would be difficult for him to enter the realm of immortal cultivation.

However, as the bronze tower is suspected to be a treasure passed down by a certain immortal cultivation sect, it was clear that they had considered the possibility of it being obtained by someone without spiritual roots.

Therefore, when Naraku first entered the Bronze Tower and was recognized as its master, the Bronze Tower displayed its power to turn decay into magic, infusing his body with a divine power.

This mysterious power caused his body to transform, thus shaping his spiritual root.

However, it's possible that the Bronze Tower consumed too much energy while traversing the world, which is why it only created a low-grade spiritual root for him.

This gave him the foundation for cultivating immortality, but the cultivation aptitude brought by a low-grade spiritual root is relatively poor.

It's like the breathing of spiritual energy.

With the same cultivation method, the better one's spiritual root, the more spiritual energy one can absorb with each breath.

Conversely, the less the better.

Furthermore, the True Qi Shadow Clone successfully absorbed the spiritual energy.

This undoubtedly proves that Naraku can use his True Qi Shadow Clone Technique to accelerate his cultivation and thus make up for his lack of spiritual roots.

Time passed little by little.

Naraku did not rush to dispel the True Qi Shadow Clone, but allowed it to continue absorbing spiritual energy, wanting to see how far it could cultivate.

Bang!

About half an hour later, suddenly, the True Qi Shadow Clone actively dispelled itself.

No, to be precise, it was the continuous absorption of spiritual energy that caused his body to burst.

The moment the True Qi Shadow Clone dissipated, Naraku immediately felt a surge of spiritual energy within his body.

This startled him. Without hesitation, he immediately sat down cross-legged and began to circulate his nameless cultivation technique to refine the surging spiritual energy.

After circulating the energy for several cycles, the spiritual energy was refined into true energy, which improved Naraku's cultivation level.

"It seems I was too optimistic. Although the True Qi Shadow Clone can absorb and exhale spiritual energy, it is ultimately just a clone. Therefore, it cannot directly refine the absorbed spiritual energy into true qi. Instead, it can only feed back the absorbed spiritual energy to me for me to refine."

Naraku, having refined the spiritual energy, did not rush to get up. Instead, he sat down on the ground and began to ponder.

The dissolution of the True Qi Shadow Clone is achieved not only through the feedback and inhalation of spiritual energy, but also through the experience of cultivation.

True Qi Shadow Clone is indeed different from Chakra Shadow Clone; it can project spiritual roots and breathe in and out spiritual energy.

However, Naraku also discovered a problem from his experience cultivating the True Qi Shadow Clone technique.

That is, true qi is different from sage chakra.

The latter is the fusion of natural energy and chakra, while the former is the fusion of spiritual energy and spirit.

Anyone here? Single-player games are so boring. If anyone is, please let me know in the comments so I know someone's watching.

Chapter 11 Efficiency Improvement

The essence of the True Qi Shadow Clone is merely an energy body constructed from True Qi. Even if a spiritual root can be projected onto the clone, it cannot, like Naraku himself, fuse the spiritual Qi he breathes in with his essence, Qi, and spirit, thereby refining it into True Qi.

Naraku frowned slightly.

If the True Qi Shadow Clone cannot refine spiritual energy, then the cultivation assistance it provides will undoubtedly be greatly reduced.

After all, if one cannot refine spiritual energy into true energy, in addition to reduced efficiency, the duration of the true energy shadow clone will also be limited.

Just like the True Qi Shadow Clone, absorbing too much spiritual energy will cause the body to burst.

In other words, there is a limit to the amount of spiritual energy that a True Qi Shadow Clone can contain.

This upper limit depends precisely on his cultivation level.

Naraku had only been cultivating immortality for less than half a month.

With his inferior spiritual root, coupled with the fact that the spiritual energy concentration in the Naruto world is far less than that in the cultivation world, his cultivation progress naturally cannot be very fast.

In fact, his current level of cultivation is thanks to the nameless cultivation technique.

Although this cultivation technique is not even specifically named in the Bronze Tower's heritage, it must be said that this cultivation technique is definitely the core heritage of the Bronze Tower.

If I had to describe it, I would call it a cultivation version of the Nine Yang Divine Skill.

Its techniques are practiced and it possesses many extraordinary characteristics.

The following statements can be summarized as follows:

First: The amount of spiritual energy it can absorb far surpasses that of ordinary cultivation techniques.

Second: The speed of true qi circulation is extremely fast, and ordinary consumption can be recovered almost quickly.

Third: When circulating true qi, even ordinary punches and kicks can unleash tremendous power.

Fourth: It has extraordinary defensive capabilities. Not only does its true energy automatically protect the body when attacked, but it also has the effect of deflecting external forces.

Fifth: After entering the path of spiritual practice, one's own comprehension will be enhanced.

Sixth: It possesses miraculous healing effects, preventing people from contracting any diseases and resisting all poisons.

For example, Naraku was able to continue his cultivation by using True Qi Shadow Clone Technique after exchanging Lightning Release with his Shadow Clone, because the True Qi he consumed was quickly restored under the influence of his Nameless Technique.

Let's return to Naraku's current cultivation level.

Thanks to the extraordinary nature of the nameless cultivation technique, his cultivation speed was comparable to that of a mid-grade spiritual root.

This is because the spiritual energy in the Naruto world is not as strong as that in the cultivation world. If he were in the cultivation world, his cultivation speed would probably be able to catch up with those cultivators with high-grade spiritual roots.

This shows how helpful a good exercise method can be.

This is enough to prove the extraordinary nature of the nameless martial arts technique.
