"Aside from our own chakra interference, what is the reason why we can't perceive the natural energy?" Rokuzawa fell into deep thought again.

The interference of their own chakra is not the main cause, the root cause is still their cognitive impairment of natural energy.

If you can sense the natural energy just by emptying the chakra in your body, then it is too easy to cultivate immortal arts.

You must know that as strong as Madara Uchiha, even if he has the 'Eternal Kaleidoscope Writing Wheel Eye' and the legendary 'Reincarnation Eye', he can't really see the existence of natural energy.

In the end, during the Fourth Ninja World War, he still used the ability of the 'Reincarnation Eye' Hungry Ghost Dao to forcibly absorb it from the body of the Thousand Hands Pillar, and only then did he obtain immortal energy.

This shows that human beings do have cognitive impairments in natural energy, so even the most top-level children's art cannot see the objective existence of natural energy.

"Why does this cognitive impairment exist?" Rokuzawa was confused.

Compared to human beings, spiritual life does not seem to have such a problem, to be precise, it is not serious.

He had consulted the Great Elder Panda, and the pandas only needed to practice seriously and slowly absorb the natural energy to evolve the essence of life, and they would naturally be able to get through this hurdle, so that they could truly feel the existence of the natural energy.

"Why is there such a difference?"

"Could it be that the nature of life is different?" Rokusawa thought of more.

Careful comparison, in addition to the difference in appearance, the difference between spiritual life and human beings is mainly reflected in the affinity for natural energy.

They are closer to nature than humans.

Like Toad Ji, even if he has not cultivated to become an immortal, in the process of growth, he will involuntarily absorb some natural energy and integrate it into his body to reach a certain amount.

When performing ninjutsu attacks, it will also involuntarily attach some natural energy.

Although it is not as good as the formal immortal arts, it does have some of the effects of immortal arts.

This is also the reason why in the fourth ninja world war in the previous life, in the face of a water bomb that Toad Ji spit out at random before leaving, the six Uchiha Obito also need to seriously resist it, instead of carrying it with his body.

And although humans can rely on instinct to absorb a little bit of natural energy, this amount is so small that it is almost negligible.

This result is due to the difference in the affinity of natural energy between the two parties.

"Then why is there such a difference between human beings and spiritual beings?" Rokuzawa began to think further.

In terms of natural affinity, immortals are naturally the strongest, then spiritual beings, and finally humans.

Further sort out the relationship between these three.

Through the cultivation of immortal arts, spiritual beings can make their own life essence be transformed, so that the immortal state can be permanently solidified and become a real immortal, instead of being like humans, who can only obtain a short duration.

Then, the key to improving the affinity of natural energy in spiritual life lies in the evolution of the nature of life.

They fuse natural energies to cause their bodies to evolve in a tendentious way, and it is only natural that their natural energy affinities are enhanced.

Thinking of this, Liuze suddenly came to a conclusion.

"In this way, if I want to truly perceive the natural energy, I must also integrate the natural energy and evolve my body."

Knowing this, he immediately thought of something more.

Cultivating immortal art is actually a process of absorbing natural energy and promoting the evolution of life.

It's the same for spiritual life as it is for human beings.

It's just that, because of their congenital deficiencies, human beings can't directly do it in one step like spiritual life, and can only cultivate that temporary immortal state.

But as far as the end point is concerned, the final result of a human immortal will also become a spiritual life, a permanent immortal.

As for those innate immortal physiques, it is actually the stage between spiritual beings and true immortals.

They are closer to nature than spiritual beings, but they still need to evolve further before they can reach the permanent immortal state of the slugs.

"It seems that if you want to truly perceive natural energy, you can only integrate your own sensory organs into the evolution of natural energy and deepen your affinity for natural energy!" Rokuzawa sighed secretly.

I figured out everything, but there is no shortcut, I can only accumulate little by little, so that the quantity changes into qualitative changes.

However, it wasn't all meaningless to understand this, at least he understood the direction of his cultivation and understood the root of immortal arts.

Even in this stage of cultivation where he is unable to control the natural energy freely, he is not just like everyone else, he can only move forward in ignorance, he can also grasp certain advantages.

So, Liuze silently calculated in his heart.

"Human perception is mainly composed of five senses, namely eye, ear, nose, tongue, and body."

"Through the power of these five senses, people and other beings are able to perceive the world."

"As for consciousness, it is the spiritual perception that comes from the soul."

"Humans, on the other hand, have cognitive impairments in natural energy, so they cannot directly use their consciousness and five senses to perceive and observe."

"Therefore, it is necessary to absorb natural energy little by little, so that the five senses on the body can be evolved."

"When the five senses are evolved, and the existence of natural energy is objectively perceived, it will naturally be able to break the cognitive barrier, so that consciousness can also evolve simultaneously."

"Therefore, my next practice should start with the five senses, and the five senses are the first parts of my body to perceive the existence of natural energy."

"By focusing on how they change, I can break down the cognitive barrier faster."

Although by swallowing purple jade bamboo shoots, you can absorb natural energy and allow your whole body to evolve, not all of them will help Rokuzawa.

For example, his muscle cells, even if they are fused with natural energy evolution, cannot skip the five senses in the case of cognitive impairment, allowing him to directly feel the natural energy.

Immediately, Rokusawa focused his next observation on his tongue.

Purple jade bamboo shoots are food, which is absorbed by him by chewing and devouring.

Based on this foundation, among the five senses, the most affected by the purple jade bamboo shoots should naturally be his tongue sense. The influence of the other four senses is slightly smaller, and the evolution will be much slower than that of the tongue senses.

If you can focus on the changes in your tongue, you will definitely be able to break the cognitive barrier faster than normal people.

After all, if ordinary people don't understand these things, they can only rely on the accumulation of time little by little, and wait until the five senses have evolved to a certain level to break the cognitive barrier.

As time passed, the purple jade bamboo shoots were further absorbed, and the natural energy accumulated in his body again, producing another round of erosion and mutation.

But this time, because of the focus on the tongue, Rokuzawa faintly felt that the previous feeling of the lake was much clearer.

Comparing the rest of his body closely, he found that the feeling of the tongue area was indeed much clearer.

"It seems that my analysis is completely correct!"

Rokuzawa was excited, and became more and more focused on perceiving the changes in the tongue area.
