After that night, Lei Luo began to devote all his body and mind to the cultivation of the immortal mode, with the help of the presence of toad oil, he immersed himself in sensing natural energy, and tried his best to explore the connection and difference between space-time energy and natural energy.

Based on the analysis of all the information obtained so far, Lei Luo gradually understood the existence of these two forms of energy, and slowly figured out their principles:

To put it simply, space-time energy and natural energy are intertwined and fused with each other, and they complement each other, and they should be inseparable from each other.

At least, in the body of an old toad like Fukasaku, the relationship between space-time energy and natural energy is like this, which is the key information that Lei Luo perceives by touching the other party's body.

But on Lei Luo's side, the situation has changed, because he can sense the space-time energy in the natural energy, or rather, the natural energy in the space-time energy, and separate the two, and selectively ingest one of the energies into the body.

On the surface, a veteran immortal like Fukasaku could not sense space-time energy, which seemed to prove that space-time energy was far more subtle than natural energy, and more imperceptible and untouchable, invisibly showing the essence of space-time energy being higher than natural energy in terms of rank.

For example, in the order of two rituals giving birth to four elephants, and four elephants giving birth to eight trigrams, space-time energy is the two yi, and natural energy is the four elephants, gossip.

Space-time energy forms the material basis, and natural energy derives all things on this basis, this is Lei Luo's understanding, although he doesn't know whether it's right or not, but judging from the various phenomena observed so far, this guess is undoubtedly quite reliable.

It was also from this point of view that Lei Luo felt that the reason why the Great Toad Immortal was able to predict the future might not only be because of its talent in this area.

After thousands of years of accumulation, it is likely that the Great Toad Immortal has the ability to time system because of the huge amount of natural energy stored in the body, so the quantitative change causes the qualitative change, and the initial contact with space-time energy.

"Fukasaku Immortal, I wonder if you have ever tried to perceive natural energy in a subtle way?"

"It's like using a magnifying glass to observe every line on the palm of your hand, using the taste buds on your tongue to taste every microsecond of smell change in the air?"

Sitting under a waterfall made of toad oil, Relo was bare, revealing his muscles, and under the impact of the faint yellow liquid that was constantly pouring above his head, he suddenly stopped thinking and looked up at Fukasaku on the shore.

Maybe Lei Luo's question was quite unusual, and he frowned and thought for a while, and after a while, he replied in an uncertain tone:

"It's true that the old man has carefully sensed natural energy, but I don't know if my subtle sense is as you described."

"I want to hear about it." A look of interest appeared on Lei Luo's face at the right time, and he said with a smile.

Fukasaku put his hands on his chest, coughed twice, organized his language for a while, and then said unhurriedly:

"Now that you know the principle of the Immortal Mode, then I'll tell you about the first time I condensed the Immortal Chakra."

After about ten minutes, after listening to Fukasaku's slow statement, Lei Luo lowered his head and held his chin in his hands, and fell into a deep state of thought again.

Fukasaku's subtle perception is not so much about understanding the nature of natural energy as it is about studying the optimal ratio of natural energy and spiritual energy with physical energy, and how to create the highest quality immortal chakra.

For example, condense and compress the density of natural energy, and make it so pure that it matches the superior physical and mental qualities of the toad family.

In this process, Fukasaku does not talk about the microscopic nature of natural energy itself, it only knows that natural energy originates from the world, and it is an energy that exists in heaven and earth, just like the air that living beings breathe.

Like two oxygen atoms combine to form an oxygen molecule, an oxygen atom and two hydrogen atoms combine to form a water molecule, natural energy, this substance, in Lei Luo's understanding, must also have some trace elements.

Studying its microscopic atomic composition may have the opportunity to understand the nature of natural energy, and then the nature of space-time energy, and finally reach a true understanding of the cosmic cornerstone of the Hokage world.

Although it is conceivable that this level of research will inevitably be full of resistance, after all, he has not had an effective microscopic intervention method until now, but this topic is undoubtedly very valuable for research.

After this trip, let's let the scientific research institute and the industrial park open another project, natural energy, which may really be one of the levers that pry the earth.

After finishing his thoughts, Lei Luo came back to his senses, and saw that Fukasaku was staring at him, with a hint of urging in his eyes, he knew that the time had been delayed for a long time, and he immediately entered the state of sensing natural energy.

Although it has only been three days since he came to Miaomu Mountain to cultivate, and most of them have spent most of his time exploring the application of space-time energy, and successfully made the product of time clone, Lei Luo actually doesn't care much about this time.

This is because the natural energy, now, after selectively ignoring the space-time energy, was quickly sensed by him who had calmed down.

Maybe it's because the spiritual power has completely surpassed ordinary humans, maybe it's the intercolumnar cells in the body that are working, or maybe it's because the effect of toad oil is really powerful, in short, the step of inducing natural energy was completed smoothly.

Then, just as Lei Luo was about to make persistent efforts and directly carry out the second part of his cultivation, that is, ingesting natural energy and creating immortal chakra, an unexpected call interrupted his cultivation steps.

"Daddy, Lei Luo, excuse me!"

Hearing the identity of the caller, Lei Luo was a little unhappy in his heart, but he still opened his eyes patiently, looked at Zhima who was running in a hurry, and then saw that the other party was holding a thick pile of documents in his hand.

Realizing that these eighty percent were looking for him, Lei Luo sighed helplessly, stood up with his legs slammed on, and then flew over the pond with one step, and instantly arrived at Fukasaku Shima's side.

"Lei Luo, the document sent by Konoha said that it was waiting for you to get an idea." Seeing Lei Luo flash in front of his eyes in an instant, Zhima was not surprised, and directly handed out the document bag in his hand, which was taken by Lei Luo, and after opening it, he carefully flipped through it.

Before leaving, Lei Luo gave Ye Naiyu a lot of authority, and he felt that the other party should not bother him with ordinary trivial matters, so he read it very carefully, for fear of missing something big.

Looking at it, Lei Luo's brows furrowed slightly, not because of the mess in Konoha, but purely because of these things on the documents, which were simply a bunch of trivial things in his mind.

Ye Naiyu, is it a little too careful?

In other words, mother-in-law?
