I, Uchiha Yu, am solely focused on cultivating immortality

Chapter 67 Sudden Enlightenment

With the breakthrough completed, wind-attribute natural energy merged into his meridians, further enhancing Uchiha Yu's digestive power. The digestion speed of rare metals increased, and both natural energy and chakra experienced a rapid increase.

But the worst-case scenario is that the growth rate gets completely out of control.

Uchiha Yu understood that he had to suppress the rate at which his ki was growing, and he absolutely could not let his ki become dominant, otherwise his body and mind would be dragged down.

So he sealed his pores to prevent the inflow of natural energy, using the natural energy to suppress his body cells, allowing the cells to act as reservoirs to hold more chakra.

The most important thing is to reduce the digestive capacity of the stomach, stop the digestion of the strange metals, and fundamentally reduce the growth rate.

During this process, Uchiha Yu was without thought or intention, and his body naturally assumed the Hunyuan stance, making various movements with the flow and changes of Qi, all naturally and spontaneously.

The disturbances in the natural energy of the outside world have long since ended. This is merely a stage breakthrough in the Foundation Establishment stage, and it is completely incomparable to the disturbances that occur when one breaks through the Foundation Establishment stage in a hundred days.

As the effects of the lightning gradually subsided, Miwa Masayo returned to normal and immediately used a fire jump to return to Uchiha Yu's side.

But at this moment, Uchiha Yu's Hunyuan Zhuang had entered the Natural Summoning Realm, concealing all his aura, sealing off all internal and external communication channels, and merging his entire being into the world and nature.

This was a great opportunity. The ninja world revealed to Uchiha Yu some of the most fundamental rules, and the laws governing the universe were laid bare.

However, in Miwa Masayo's view, Uchiha Yu had indeed inexplicably entered a state of silence, and as the silence continued, Miwa Masayo also fell into panic.

The tabby cat began to sit, then circled around Uchiha, finally jumping onto his shoulder and meowing loudly in his ear. When she received no response, she frantically scratched his hair with her paws and even licked his cheeks, desperately trying to wake him.

Miwa Masayo was really anxious. Only then did she realize that she had become so used to being with Uchiha Yu that she couldn't imagine how she would survive without her human in the future.

Fortunately, Uchiha Yu didn't encounter any problems, but rather entered a wondrous spiritual realm, which, in cultivator terms, is called "sudden enlightenment."

For Uchiha Yu, ki includes both the natural energy circulating in the meridians and the chakra in the body's cells, but these two are different.

As the strange metal was digested, the natural energy was strongly stimulated, and the newly acquired wind element became restless, which in turn affected the fire element, which was suppressed with the help of the earth element.

While suppressing the wind element, it is also necessary to ensure its strengthening so as to quickly establish a tripartite balance of power, lest the natural energy of the wind element be excessively suppressed and become stagnant.

Chakra is another matter entirely.

The digested metal released a large amount of chakra. The quantity of chakra wasn't particularly terrifying, but the quality of the chakra was beyond Uchiha Yu's comprehension.

If the chakra released by the strange metal is steel, then the chakra repeatedly forged by Uchiha Yu is just water vapor; the two are not comparable at all.

Faced with such a disparity, his chakra had no room to resist and could only allow his cells to be infused with chakra, which then took the initiative and merged with the original chakra.

If Uchiha Yu's foundation hadn't been Sage Mode, and if his natural energy hadn't been strong enough after reaching the Foundation Establishment stage, the chakra of the rare metal might have invaded his meridians.

When the external chakra comes into contact with natural energy, the two will automatically combine to form Sage Chakra, and Uchiha Yuu will be finished.

His path will be destroyed, forcing him to return to the traditional path of the sage in the ninja world. While his combat power will soar, his path to immortality will be almost severed.

The native Sage Mode practitioners in the ninja world are extremely powerful in combat. The Sage of Six Paths was able to defeat his mother, who was of a higher level, using Sage Mode. Hashirama Senju was able to overpower Madara Uchiha using Sage Mode. Naruto Uzumaki was able to overpower the Rinnegan using Sage Mode.

But so what? Uchiha Yu didn't even look at her.

It should be noted that Hagoromo Otsutsuki and Hamura Otsutsuki were originally long-lived beings, but because they cultivated this kind of immortal technique, they were both unable to live for a thousand years and died.

Even if the soul hides in the Pure Land, it is still death; nothing is as comfortable as longevity.

Toad Pill was old and frail, White Snake Immortal was exhausted, and only Slug Immortal's condition was unknown.

In short, this kind of immortal path is highly problematic and is considered rubbish by Uchiha Yu.

Immortality that cannot lead to eternal life—what rubbish that is!

But maintaining balance is incredibly difficult, especially when one's essence, energy, and spirit are affected by external forces during a breakthrough, causing the energy to increase exponentially. Uchiha Yu himself simply cannot maintain this balance.

Fortunately, he entered a state of enlightenment, in which his soul resonated with heaven and earth, and heaven and earth accepted his body, making it a part of nature.

The human body is merely a microcosm of nature, and cannot be compared to the vast world of heaven and earth.

The differences between Uchiha Yu's physical evolution, chakra and natural energy growth, and spiritual growth are enormous, but when incorporated into the natural world, the so-called differences become insignificant, even minuscule.

In the grand balance of nature, this difference is silently eliminated.

With the balance of vital energy and spirit achieved, digestive ability was also brought under control. Through the coordination of internal and external natural communication, the rare metal, as an element for growth, was successfully incorporated into Uchiha Yu's life system.

As the new life system matured, Uchiha Yu's body gradually became separated from the world and nature, and little by little he became independent from the world and nature. His soul was also rejected from the world and nature at the same time.

Thus, the crisis that led to this breakthrough was completely eliminated, and the opportunity for enlightenment also came to a complete end.

Uchiha Yu benefited from the misfortune, making a significant leap forward in his Foundation Establishment progress. Driven by the new chakra, his physical strength doubled, and his spirit also experienced a tremendous increase.

In the realm of the mind, a new heart shape has been conceived and is undergoing its final solidification. It is unknown what form this heart shape, belonging to the wind element of the lungs, will take.

But the greatest gain was the insight into the most fundamental rules and the laws governing the universe that he saw during his enlightenment. Although he couldn't understand them or remember them, they left a slight impression on him deep in his mind.

But this is already a precious treasure that can benefit one for a lifetime, and it will take Uchiha Yu a lifetime to slowly digest it, and this "lifetime" may be infinite.

Even now, Uchiha Yu has already made significant gains.

In a moment of enlightenment, Uchiha Yu used the power of cosmic deduction to prove that the cultivation system of his previous life was unworkable.

The natural energy that exists in the ninja world does not match the five elements, the most basic rules of the cultivation system, so the higher-level laws and structures are naturally also flawed.

Moreover, the higher one goes, the greater the errors become that cannot be corrected, to the point that the existence of the Nascent Soul cannot be deduced at all.

The path of cultivation in the ninja world is blocked. Even if there is a superficial similarity, it only goes up to the Golden Core stage. There are no elements to learn from if you go any further.

This deduction made Uchiha Yu realize that he was extremely lucky to have started with the fire element. If he had started with any other element, he would not have been able to establish a balance between the three elements of wind, fire, and earth.

Neither the conflict between water and fire, nor the turbulence between wind and thunder, could achieve the most basic stability, and Uchiha Yu had no chance to merge with the natural world.

Therefore, there are only two possible outcomes for his breakthrough today:

Either natural energy and chakra merge, and his unique Sage Mode comes to an end, turning him into an ordinary sage native to the ninja world.

Either the natural energy goes berserk, or this is the end of his life.
