If Rokuzawa wants to perceive the existence of natural energy, he must understand why, and then he can prescribe the right medicine to solve the problem better and faster, rather than relying on luck.

"Could it be that it's because the natural energy is different from the chakra?" Again, he had a guess.

Chakra itself is also a kind of energy, a kind of biological energy that has been artificially transformed and refined, and then go back to the roots, biological energy comes from the food ingested by the human body from the outside world.

The energy contained in food, such as wheat and rice, comes from photosynthesis, and the source of photosynthesis comes from solar energy.

So, the roots of natural energy and chakra energy are actually the same thing.

However, after many transformations, the chakra energy they refined had been tainted with too many things.

It's like a clear spring, after many repeated uses, it will naturally be mixed with many impurities, and it will never be the original appearance again.

This is also the source of the difference between chakra energy and natural energy production.

Thinking of this, Rokuzawa couldn't help but be shocked.

"Could it be that it's because the chakra is more 'dirty' that the natural energy is more inconspicuous and difficult to observe?"

There is already this cognitive barrier between normal people and natural energy, and coupled with the interference of chakra, it is even more difficult for them to recognize natural energy.

"Perhaps, I can drain as much chakra as I can from my body before I try!" Rokuzawa suddenly had an idea.

Immediately, he spread out his hands, silently condensed them in the palm of his hand, and took the initiative to disperse them in the air.

And as Chakra was lost little by little, a sense of weakness couldn't help but creep up in his heart.

Without the support of Chakra, the ninja is just an ordinary person with more acute senses.

After nearly ten minutes, he felt that the chakra was almost exhausted, and he didn't force himself anymore, silently gathered his mind, and continued to sense his physical state.

Although he can still squeeze his physical strength to refine the chakra, his purpose is not to completely drain the chakra, but to expel the chakra that has already been refined.

If you really want to squeeze to the limit at all costs, it will kill people.

After all, chakra is a mixture of the body's biological energy and spiritual energy.

However, Rokuzawa ran out of chakra and was extremely weak in his body, but his spirit became excited.

Because he found that his spiritual perception did seem to be much more sensitive than before, as if he had taken off a thick coat, his entire mental state was much more relaxed, and many places in his body that he had not perceived in the past have become much clearer.

"It seems that I guessed correctly, the presence of chakra will indeed interfere with my spiritual perception!" Rokuzawa secretly rejoiced.

On the outside, this interference is not obvious, but on the inside, it is very serious.

In particular, the natural energy and the chakra energy are of the same origin, and it is difficult to distinguish between the two when they are mixed, and coupled with the cognitive impairment, it is even more difficult for him to accurately perceive the existence of the natural energy.

Now that there was no chakra distraction, it was easier for him to feel exactly the presence of natural energy.

Immediately, he concentrated his energy and carefully felt the changes in his body.

After about an hour, the natural energy that he digested and absorbed accumulated to a limit, and his body could no longer bear it, and involuntarily began to change.

As usual, the flesh and blood tissue closest to the stomach and small intestine became more and more active, and then this state began to spread rapidly around like an infectious disease.

When the mutation spread to the surface of the body, the exact change of the mutation was also revealed in front of Rokuzawa's eyes.

I saw that the muscles were bulging, the muscles were expanding, and some black and white hairs were growing rapidly from his skin.

He's panda-like again.

However, this time is different from usual, because without the interference of his own chakra, Rokuzawa also has a clearer grasp of the changes in his body.

Although he still did not observe the existence of natural energy for sure, he faintly felt something in the midst of this erosion and upheaval.

"There's hope, there's hope, there's hope!"

Rokuzawa was so excited that he couldn't help but shout out loud.

Although he was still far from success, he had already seen the direction of success and really took the first step, unlike the previous month of penance that had been standing still.

Hearing his exclamation, the originally sleepy four-headed panda was suddenly startled.

"What's hopeful?"

"Can you already feel the energy of nature?"

……

The four pandas asked one after another, and even the slug immortal clone coiled on Liuze's shoulder was curious.

"Not quite successful!"

Rokuzawa shook his head and said with a smile: "However, I have already found the direction, and it may not be long before I can get through the first hurdle." ”

"It's really fake!"

The four pandas could no longer sit still, and immediately pulled up and down.

Of course, it's hard to say whether they are curious or take the opportunity to avoid cultivation.

When the slug immortal saw this, he immediately scolded: "You four stupid bears, who made you up!" ”

"Hurry up and sit back for me to continue cultivating!"

"You've been cultivating for decades or still standing still, don't you know how to put your heart into it?"

Hearing this, the four-headed panda suddenly stopped, then glared at the slug immortal hatefully, reluctantly returned to the same place, and continued to meditate.

It's just that the slug immortals also know that this group of pandas is only superficially obedient and has not practiced seriously at all.

But if you know, you know, there's nothing it can do about it.

No matter how powerful it is, it can't control the minds of this group of pandas.

Then, it asked Rokuzawa again, "Then how long do you estimate it will take you to truly feel the natural energy?" ”

"I don't know!"

Rokuzawa shook his head again and sighed, "It's a long accumulation process, and I can't estimate how long it will take. ”

"However, I finally see hope and direction, and I am not as desperate as before."

"Then, I'm looking forward to your next progress in cultivation!" The Slug Immortal smiled and silently began to withdraw the natural energy from Rokuzawa's body.

The erosion of natural energy has intensified, and it cannot be allowed to continue.

Immediately, Liu Ze felt that the position attached to his shoulder by the slug immortal seemed to have an extra suction, sucking the kind of thing he vaguely felt, the kind of lake that he faintly felt.

And as those inexplicable things left his body, his originally alienated body began to retract again, quickly recovering towards its original appearance.

But in an instant, Rokuzawa changed back to his original appearance again.

Without wasting time, he gathered his mind and continued to think and comprehend, hoping to further accelerate the progress of his cultivation.
