Today is the hundredth day for Uchiha Yu to absorb natural energy.

He felt the change, the rate at which the natural energy was absorbed was getting faster.

In fact, it wasn't his active behavior, in the entire Konoha Village area centered on the small courtyard, all the fire attribute natural energy was restless, and it took the initiative to converge towards him.

The natural energy of the fire attribute automatically crowded out other attributes, forming a red energy vortex, and the surging tank entered the body of Uchiha Yu, integrating into the meridians without hindrance.

[It's too fast, it's too fast.] 】

[It's a little scary......]

[But there is no feeling of discomfort in the body, and it should be fine...... Bar]

[No, it's too comfortable, I'...... Can't stop......]

The natural energy of the entire Konoha Village is rioting.

If there is a strong immortal in Konoha Village, he will be able to perceive the terrifying natural energy vortex and follow the flow of energy to find Uchiha Yu.

Very fortunately, there are no immortal powerhouses in Konoha Village at this time, and there are not even ninjas who can vaguely sense the energy of nature.

Naruto Sarutobi Hizashi is a natural politician, and Shinobu Dark Shimura Danzo is obsessed with intrigue, and people with dirty hearts are not qualified to feel the energy of nature.

Tsunade among the three ninjas is talented, and her grandfather is the strongest immortal powerhouse, inheriting her sensitive natural perception talent. But Tsunade's heart is not stable, and she even suffers from a mental illness called hemophobia, which is like a thick black cloth over her eyes, and she can no longer perceive natural energy.

Besides, Tsunade is currently running away from home and is not in Konoha Village.

The Toad Immortal is also pure in heart, and he has succeeded in cultivating the immortal art of Miaomu Mountain, of course, he can sense the changes in natural energy, but he is stranded in the Land of Rain, and he is not in Konoha Village.

Lengjun Orochimaru, a scientist who really understands natural energy, has to wait until twenty years later to find Shigego, in this child who can automatically become an immortal, has an intuitive understanding of natural energy, and develops a spell seal, before he can officially understand natural energy.

Because no one knows, there is maximum security.

No one bothered, Uchiha Yu gradually entered a state of forgetting things and me, fugue void, and the natural energy of the fire attribute in the meridians in his body became stronger and stronger, and finally forced the last trace of chakra out and was forced to return to the cells of his body.

There is only pure natural energy in the meridians, and the speed of the red torrent naturally accelerates, producing a stronger suction, and more natural energy pours in, and the red torrent becomes denser and denser, and gradually there are signs of atomization.

The dense atomized natural energy flowed at high speed in the meridians, converging towards the Rendu second vein in the center of the body in the Uchiha's natural state of tranquility and inaction.

From the curved bone point near the perineum, the midline of the body is played, driving the qi and blood to rise and surge, and after meeting with the head, the qi and blood are agitated, and the yin and yang are intertwined, and the nature has undergone a slight change.

[It turns out that this is the so-called dragon and tiger convergence, yin and yang Kaitai, it is really ...... It's cool! 】

After the natural energy converges, it turns around, and still goes down along the second vein of Rendu, penetrating through the sea of yin veins and the sea of yang veins of the human body, and converging again in the Qugu acupoint.

The two natural energies collided with each other, causing ripples, forming a resonance with the three inches above the curved bone acupoint, and the outline of the dantian that did not exist in the real became clearer and clearer.

[This is the dantian I have been looking for, but I have never been able to find it? It turned out that the dantian was not found, but opened up by itself. 】

After the impact, the natural energy will turn upwards again and start a new cycle.

After twelve rounds of reciprocation, Uchiha Yu lost his external perception as if he had been struck by lightning, and inexplicably felt a sense of rapid fall, and when he opened his eyes again, he found himself entering a chaotic space.

The red mist in the space was steaming, just like the clouds before the rainstorm, and the atmosphere was oppressive and impacting Uchiha Yu, and the light and quiet state of mind gradually had an unstable feeling.

He felt the crisis, and it seemed that after a heart breakdown, he would encounter a fatal hazard.

At the same time, something was also being conceived in the red mist, and his intuition told Uchiha Yu that what was conceived was the hope of lifting the danger, and he couldn't help but start urging.

[Hurry, hurry, no matter what the change is, hurry up, hurry up! ] 】

At the same time, he cheered himself up.

[Hold on, I won't die because of such a trivial matter.] 】

I don't know how long I held on, but there was a thunderstorm in the clouds and mist, and the red fog condensed into red raindrops, falling down in a trickle.

Uchiha Yu's heart suddenly relaxed, and an unprecedented ecstasy poured out, everything he felt and knew was transparent, and the whole person was as cool as flying.

Super cool!!

Although Uchiha Yu has never smoked grass in his life, he just feels that it is more enjoyable than sucking grass now.

If cultivating immortals is like this, it is a matter of course to indulge in cultivating immortals.

Just when Uchiha Yu was intoxicated with cultivating immortals, the red raindrops became more and more numerous and bigger, and a torrential rain erupted in the space.

The red mist quickly faded, and when it almost disappeared, layers of red mist poured in from all directions, and immediately turned into a downpour.

Uchiha watched as the water began to accumulate under the space, and it was clear that there was no ground, and the rain was just accumulating out of thin air, accumulating into a small puddle.

As the precipitation continued, the surface of the water gradually increased, and Yuu Uchiha's heart became clearer and clearer, breaking free from the intoxicating refreshment.

He looked at the growing puddles, and his heart was filled with a deep joy of peace.

It's a feeling of bliss.

When the water is large enough to be called a pool, the influx of red mist stops, and the red rain gradually stops.

Uchiha Yu felt himself involuntarily rising, his perspective getting farther and farther away, his speed getting faster and faster, and he soon saw the full picture of the space.

It was an oval like an egg, with a distinction between up and down, but no difference between heaven and earth, with a faint red mist above and a sparkling pool below.

【Dantian! 】

Intuition tells Uchiha that this is the dantian, a miracle that exists between the real and the unreal, capable of accumulating natural energy.

And he, Uchiha Yu, has just condensed the natural energy of the gaseous state into a liquid state, greatly improving the density and purity of the energy, and it should be called Tsukiki.

[From the time I absorbed the first red point of light, exactly one hundred days have passed, and a hundred days have been built. 】

What if we can't build the foundation today? 】

Uchiha Yu didn't continue to think about it, he had already succeeded in building the foundation, and it was pointless to think about the impossible things that could not happen.

As the feeling of ascending became more and more intense, he suddenly came to his senses and found himself lying on a bamboo couch in the posture of a reclining Buddha.

This is the sleeping position he unconsciously posed, obviously a strange and distorted posture, but under the dredge of the natural energy like the flow of rivers in the meridians, he can feel the unbelievable comfort of his body.

It's like the wonderful comfort of the muscles and muscles under the pain when you successfully perform yoga movements and pull your body to the limit.

Now he doesn't feel any pain and therefore feels more comfortable.

Wherever the natural energy in the meridians flows, it is like the earth moistened by the spring rain, awakening vitality.

Uchiha Yu felt every cell in his body cheering, and the rich natural energy turned into a powerful resource for the cells, pushing the body to become stronger and constantly changing.

Sure enough, it was the foundation building.
