I'm in Konoha, and I started with Ashura Chakra.

Chapter 102 suddenly turned into a cultivation story.

Having just received the real-time information transmitted by the wooden clone, Yagyu immediately picked up a new Grell Stone, sat cross-legged, and began to absorb the special energy within.

Several hundred wood clones used the Mayfly Technique to escape, leaving only a small number of wood clones still fusing with Sage Chakra.

Among them were more than a dozen wood clones, which, like the previous wood clones, successfully fused the natural energy within the special energy with the chakra in their bodies to form Sage Chakra, and red face paint appeared at the corners of their eyes.

However, just like the wooden clones before, these wooden clones' Sage Mode only lasted for a few seconds before disappearing quickly.

Immediately afterwards, these wood clones also fled far away, heading to various places in the ninja world to act as spies.

In the end, only a few wooden clones came behind Yagyu, silently protecting his main body.

If the main body is found to be out of control again, help Yagyu absorb the special energy, just like before.

Although he had mastered the technique of fusing natural energy and chakra into Sage Chakra, Yagyu still dared not absorb the special energy inside the Grell Stone all at once, just like before.

After all, the special energy of such a stone required Yagyu to create hundreds of wood clones to dilute it, and only a dozen or so wood clones successfully fused to form Sage Chakra.

If it were absorbed all at once, it would definitely enter the immortal transformation again and go berserk out of control.

So, just like the first time he absorbed it, Yagyu only inhaled a tiny bit of the special energy.

The life force contained within the special energy is negligible to Yagyu's true form.

But even this tiny amount of natural energy made Yagyu's emotions become volatile again.

Before the natural energy could affect his reason, Yagyu put down the Grell Stone, placed his hands on his lap, left hand over right hand, thumbs touching, and made a meditation mudra.

To the average person, Yagyu looked as if he were meditating.

To a ninja, it looks like extracting chakra.

In fact, Yagyu was fusing the two types of energy within his body.

However, the ratio of these two energies is a bit exaggerated; even describing it as one hundred million to one is an understatement.

Soon, Yagyu opened his eyes.

The red pupils did not change color, and no red mask appeared at the corners of the eyes.

Failed!

Yagyu's chakra reserves are far greater than those of his wood clones, which contain only a "small amount" of chakra.

Picking up the Grell Stone, Yagyu absorbed its special energy once more.

The amount inhaled this time was dozens of times greater than before.

As soon as the special energy seeped into his body, Liu Sheng's expression immediately turned ferocious, and his red pupils turned into yellow vertical pupils again.

Yagyu quickly put down the Grell Stone, made the meditation mudra with both hands again, and absorbed the natural energy containing life force according to the information transmitted by the wood clone, merging it with his chakra.

Thanks to Yagyu's efforts, the special energy containing the poison in the tonic was quickly broken down into two types of energy, one positive and one negative.

The pure life force, having just broken free from the entanglement of natural energy, immediately merged into Yagyu's 130 trillion cells, making the already vibrant cells even more active and slowly changing Yagyu's physical attributes.

The amount is still small and not easily noticeable.

Once the amount increases, the changes in Yagyu's body will become more obvious.

Once he breaks through a limit, or breaks through several limits in succession, Yagyu's Sage Body may not only be healed by Hashirama Senju without a seal, but may also have Jugo's regenerated cells expelled.

Even his Yang power and Yang Release chakra possess the characteristics of the Grell Stone, enabling him to create wells that never run dry, allow livestock to grow overnight, and even have the characteristics of Yin sealing, allowing him to maintain his youth or greatly increase his lifespan.

After all, that ancient kingdom used the Grell Stone for research on preventing aging.

However, Yagyu hadn't thought that far ahead.

At this moment, he was focused on fusing Sage Chakra.

After a long time, red facial makeup gradually appeared at the corner of Liu Sheng's eyes as he meditated with his eyes closed.

The violent aura that had been amplified by absorbing a large amount of special energy gradually stabilized.

If someone could sense emotions, they would find that Yagyu's current emotions and aura are completely different from before, when he was full of violence and could lose control at any moment.

On the contrary, his aura became extremely restrained, as if he had merged with nature, returning to his original simplicity.

Unless it is a visual perception, ordinary perception cannot judge Yagyu's strength by sensing his aura.

Yagyu slowly opened his eyes. His yellow vertical pupils had returned to normal, but the color of his pupils was no longer red, but golden.

Whether it was a change in aura or the effect of eyeshadow, Yagyu's eyes appeared indifferent, yet full of majesty and a sense of oppression.

Yagyu looked down at his hands and murmured, "Is this Sage Chakra?"

A deep blue chakra aura suddenly appeared and quickly enveloped Yagyu's hands.

Within this chakra aura, Yagyu sensed a powerful energy fluctuation.

If this chakra were unleashed, its power would far surpass that of his previous self.

If this chakra is transformed into a nature transformation, then the power of all chakra techniques, whether it be the Five Elements Release techniques, Yin Release, or Yang Release ninjutsu, will increase significantly.

In addition, Yagyu also discovered that his body had become light and airy, and even without the protection of chakra, he would be fine if he jumped from a height of tens of meters.

Under the influence of this chakra, Yagyu's physical abilities, as well as his ninjutsu, taijutsu, and genjutsu, were all greatly enhanced, just like a buff in a game.

Unfortunately, this power came quickly and went quickly.

In less than a minute, the red mask around Liu Sheng's eyes and his golden pupils faded, returning to their original state.

Immediately afterwards, Yagyu picked up the Grell Stone from the ground and absorbed its special energy once more.

Having learned from his previous experience, Yagyu quickly entered Sage Mode this time.

However, his brow furrowed slightly, and he murmured, "I can't sense it. Is it because it's nighttime, or is my Sage Chakra insufficient?"

What Yagyu said he couldn't perceive was precisely the natural energy in nature.

Even though he had already entered Sage Mode, Yagyu couldn't sense any natural energy.

If he cannot sense natural energy, Yagyu will be unable to enter Sage Mode by absorbing energy from nature, or extend the duration of his Sage Mode.

When entering Sage Mode, you will also need to use the Grell Stone.

This Sage Mode is similar to how Jugo gave his Sage Chakra to Sasuke Uchiha during the Fourth Shinobi World War, giving him a different kind of Sage Mode.

Of course, Yagyu knew that his Sage Mode was very pure.

The reason why I can't sense natural energy is probably because my immortal body hasn't fully developed yet, and my compatibility with natural energy is not high enough.

Once the Sage Body is fully developed, just as Hashirama Senju said, natural energy will automatically come to him.

Soon, Yagyu's Sage Mode was deactivated again.

"what?"

Having just exited the incredibly powerful Sage Mode, Yagyu seemed to sense something, his face beaming with delight as he exclaimed, "Just as I suspected, the Yang Release chakra... is getting stronger!"

Yes, Yagyu sensed the life force within his body.

That was a life force that had broken free from the entanglement of natural energy, a life force of unparalleled purity.

These life forces are fusing with his cells, making them more vibrant and unleashing more and stronger physical and mental energy.

If this continues, the amount of chakra Yagyu can extract will become even more astonishing.

Once the Sage Body is fully developed, Yagyu's chakra reserves will be so vast that even Naruto, who also possesses the Sage Body, plus half of the Nine-Tails' chakra, can only match his, or even—almost match mine.

Just as Yagyu had thought, the life force within the Grell Stone could allow his immortal body to quickly reach its full potential.

It doesn't matter if we can't perceive natural energy now.

As long as he continues to absorb the special energy from the Grell Stone, Yagyu's immortal body will grow rapidly.

Once he reaches a certain level of maturity, he will naturally be able to sense natural energy. Just like Hashirama Senju, he can enter his own Sage Mode by clapping his hands together.

Moreover, its endurance is so long that unless its own chakra is exhausted, it can absorb natural energy and fuse with Sage Chakra while fighting.

Thinking of this, Liu Sheng's expression suddenly turned strange, and he muttered, "The special energy contained within the stone, absorbing it can enhance one's energy and strength... Why does this feel so familiar?"

Looking at the large expanse of stones shimmering with green light on the ground, Liu Sheng remained silent for a moment, his lips twitching slightly.

Good heavens, isn't this a spirit stone?

No wonder it felt familiar; it turns out it suddenly turned into a cultivation story!

While mentally complaining, Yagyu quickly collected the Grell Stones from the ground and put them into his spatial backpack.

Once the number of overlapping spaces in a single grid reached ninety-nine, Yagyu stopped collecting them, then took out an extra-large storage scroll and continued collecting Grell's Stones.

However, after the explosion, the mineral veins that could destroy half the continent were completely destroyed. Even if Yagyu filled his extra-large storage scroll or even his spatial backpack, he could only take a tiny fraction of what he could get.

However, Yagyu did not intend to take it all; he only took a certain amount and then used the Mayfly Technique to escape far away.

Very few people in this era know about the Grell Stone, and only Yagyu, Naruto, and Jugo are currently capable of fully absorbing its energy.

Even Naruto, unless he learns Sage Mode and has the means to absorb chakra, cannot absorb the energy of the Grell Stone.

If Yagyu wants to absorb the life force in the mineral vein, he must first absorb the natural energy within it.

He is not yet able to absorb a large amount of Grell Stones at once.

So it would be better to just take a batch of Grell Stones back, absorb them, and then come back to collect them, or have the Wood Clone deliver them.

Anyway, with the Mayfly Technique, whether it's Yagyu or his Wood Clone, a round trip only takes a few hours.

Once the Flying Thunder God Technique is mastered, it will be done in an instant.

Yagyu, who was moving at high speed underground, was in a very pleasant mood.

Yagyu never expected that the Phantom Underground Ruins, which was originally considered the most boring theatrical version, would bring him such a big surprise.

He originally thought that the spirit communication array in the Time-Space Cave was the greatest gain.

If I can find the trick to learn the Flying Thunder God Technique, then this trip out for a break will be a huge success.

Unexpectedly, the Grell Stone vein turned out to be the real treasure.

Even though Yagyu was a transmigrator, he could only think of two ways to quickly achieve the physique of an immortal.

First, becoming the Ten-Tails' Jinchūriki automatically grants one a physique superior to that of a Sage.

Secondly, it was through the power-up provided by the Sage of Six Paths that Naruto temporarily surpassed Hashirama Senju.

However, when Naruto lost Yin-Yang Release and the Nine-Tails, his Sage Mode was clearly no match for Hashirama Senju, indicating that even in Boruto, Naruto's Sage Mode had not reached its full potential.

Without relying on external cheats, the only way for a celestial being to reach their full potential is through aging.

Now, however, Yagyu has found a new shortcut and is expected to achieve the Sage Body before Shippuden ends. How could he not be happy about this?
