I use the ninja world to help me cultivate immortality

The essence of the Qi Shadow Clone is just an energy body constructed by Qi. Even if the spiritual root can be projected on the clone, it cannot fuse the spiritual energy with the spirit and spirit like Naraku himself, and thus refine it into Qi.

Naraku frowned slightly.

If the Qi Shadow Clone cannot refine the spiritual energy, then the help it brings to cultivation will undoubtedly be greatly reduced.

After all, if the spiritual energy cannot be refined into Qi, in addition to the reduced efficiency, the maintenance time of the Qi Shadow Clone will also be limited.

Just like the Qi Shadow Clone just now, breathing in too much spiritual energy will burst the body.

In other words, there is an upper limit to the spiritual energy that the Qi Shadow Clone can accommodate.

This upper limit depends on his cultivation.

After all, Naraku has only been cultivating for less than half a month.

With his low-grade spiritual root qualifications, and the fact that the concentration of spiritual energy in the Naruto world is far less than that in the cultivation world, it is naturally impossible for his cultivation to improve very quickly.

In fact, he can now have the current cultivation, thanks to the nameless cultivation method.

Although this method of cultivating immortals has no specific name in the inheritance of the Bronze Tower, it must be said that this method of cultivating immortals is definitely the core inheritance of the Bronze Tower.

If you want to describe it, you can call it the immortal version of the Nine Yang Magic Art.

Its method has various extraordinary characteristics when practicing.

It can be roughly summarized as follows:

1. The amount of spiritual energy in breathing is far better than ordinary immortal cultivation methods.

2. The speed of the true energy rotation is extremely fast, and ordinary consumption can be restored almost immediately.

3. When the true energy is running, ordinary punches and kicks can also burst out with great power.

4. Extraordinary defense, not only will the true energy automatically protect the body when attacked, but it also has the effect of rebounding external forces.

5. After entering the practice, your own understanding will be blessed.

6: It has a miraculous effect of healing, which can prevent people from all diseases and poisons.

For example, Naraku was able to continue practicing the Qi Shadow Clone after fighting with the Shadow Clone and performing the Lightning Release without stopping. This was because he quickly recovered the Qi he consumed when he used the nameless technique.

Let's talk about Naraku's current cultivation.

With the extraordinary Wuming technique, his cultivation speed is comparable to that of a mid-grade spiritual root.

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

This shows how much help a good technique can bring.

It is also enough to prove the extraordinary Wuming technique.

"Don't be greedy. Being able to breathe in and out spiritual energy now is actually a very good result."

Naraku's frown did not last long and soon relaxed.

He is not a person who doesn't know what's good for him.

Although the Qi Shadow Clone does not have the ability to refine spiritual energy, being able to breathe in and out spiritual energy can already speed up his cultivation speed.

With such a gain, what is there for him to be dissatisfied with?

"From the experience of the Qi Shadow Clone just now, with my current cultivation, the Qi Shadow Clone that I split out with all my strength can probably breathe in and out spiritual energy for half an hour.

However, with my current Qi recovery speed, I can completely split out the Qi Shadow Clone multiple times in a short period of time, thereby increasing the number of Qi Shadow Clone."

Naraku thought quickly and soon came up with an idea.

Without hesitation, he immediately started the second round of testing.

Getting up and performing the Shadow Clone Technique again, Naraku split out another Qi Shadow Clone and let it continue to breathe in and out spiritual energy.

Then, he immediately operated the nameless technique to restore the consumed Qi.

When Qi circulates through the meridians, the breathing speed of spiritual energy is much faster than when improving cultivation and recovering.

This is a bit like the principle of a water tank.

It is much more difficult to increase the storage space of a water tank than to refill it with water after the water in the water tank is used up.

The extraordinary recovery speed allowed Naraku to recover his Qi in a short time.

He immediately used the shadow clone again, splitting out the second Qi shadow clone, and let it also start to breathe in and out spiritual energy.

He restored his true energy again and again, and split out the true Qi shadow clone again and again.

Until the first shadow clone was burst by spiritual energy because of breathing to the limit, Naraku had already split out ten true Qi shadow clones.

When the first true Qi shadow clone was released, the spiritual energy fed back was refined, which not only restored the true Qi that Naraku had just consumed, but also improved his cultivation to a certain extent.

Without pausing, Naraku continued to split out new true Qi shadow clones while refining the spiritual energy.

He refined the spiritual energy fed back by the true Qi shadow clone again and again.

After busy efforts, he gained a rapidly improved cultivation.

The sun sets and the moon rises, and the moon sets and the sun rises.

When the first ray of sunlight in the east shone into the dense woods, Naraku seemed to have practiced all night like this.

"Is it dawn? Time flies!"

Feeling the sunlight, Naraku, who was refining spiritual energy again, stopped and stretched.

Although he practiced all night, Naraku did not feel much tired.

This was not only because of the extraordinary recovery ability brought by the nameless technique, but also because of the great improvement of the true qi in his body.

One true qi shadow clone can breathe in and out spiritual energy for half an hour.

Ten true qi shadow clones can breathe in and out spiritual energy for five hours.

In other words, after Naraku refined the spiritual energy breathed in and out by ten true qi shadow clones, it was equivalent to practicing for five hours at ordinary times.

Even if the time for true qi recovery is also included.

But after feeling the improvement in his cultivation tonight, Naraku made a rough estimate and found that the results of his cultivation this night were comparable to the eight previous nights of cultivation.

This undoubtedly proved that the use of the True Qi Shadow Clone to assist in cultivation had increased his cultivation speed by more than eight times.

"Perfect! With the current cultivation efficiency, I estimate that in another month, I should be able to improve my cultivation to the first level of Qi training."

The greatly improved cultivation speed made Naraku happy.

With the concentration of spiritual energy in the Naruto world and his low-grade spiritual roots, it was definitely very fast to be able to improve to the first level of Qi training in such a short time.

"But in the current situation, I can no longer return to the apartment to practice. I can only stay in the training ground for a long time, but it doesn't matter."

Naraku thought, touching his chin.

The apartment is limited in area and obviously cannot accommodate too many True Qi Shadow Clone for cultivation.

But Naraku is not opposed to settling in the training ground.

Compared with the training in the Root Organization, such a wild life is completely child's play.

As for the Ninja School, it's all handled by the Shadow Clones, so it doesn't matter where he stays.
