Planning for the Power of the Dragon Vein

"Sure enough, the Spirit Transformation Technique wasn't Impure World Reincarnation. Although I could occupy this body, it wasn't truly replacing my original one. I could still sense the existence of my real body."

"Even this specially made clone without a soul felt a slight rejection. Was that because of chakra?"

"Confirmed. The Spirit Transformation Technique should have a time limit, but if I increased the chakra carried by the soul, the duration of the technique would increase accordingly."

"What if the chakra ran out?"

Uchiha Yansheng controlled his chakra consumption. Once it was depleted, he quickly sensed his original body calling to his soul, along with a faint discomfort coming from within the clone.

Immediately afterward, two opposing pulls appeared at the same time, as though they were demanding that Uchiha Yansheng make the choice himself.

But Uchiha Yansheng could tell that if he continued staying in this body, while he could achieve something similar to body possession, this body would eventually begin rejecting his soul.

It was difficult to describe such a phenomenon in the Ninja World.

But according to memories from Uchiha Yansheng's previous life, this was clearly a case of soul and flesh being incompatible. He only needed to find a way to increase the compatibility between the soul and the body.

Or he could simply ignore it and switch bodies every few years.

The Spirit Transformation Technique plus some secret technique that devoured souls should be Impure World Reincarnation, right?

Uchiha Yansheng guessed recklessly without the slightest concern. It did not matter if he was wrong.

After all, what he was doing now had already achieved an effect similar to Impure World Reincarnation, and he could withdraw at any time without damaging his soul.

But Uchiha Yansheng had no reason to abandon his original body anytime soon. After trying it once, he returned to his real body.

Afterward, Uchiha Yansheng used the Spirit Transformation Technique again and carefully analyzed the data from the clone.

After moving his body a little, Uchiha Yansheng activated the Byakugan. Sure enough, veins bulged at the sides of his eyes.

That should confirm it. The reason he had been able to use the Byakugan without warning before was because the Byakugan inside his body had borne the burden of activating it.

And now...

Uchiha Yansheng stared at his original body for a long while, then placed his palm over the Eight Trigrams Seal on his abdomen. He drew the Byakugan's ocular power from the seal and nourished his eyes.

In the original story, the Tenseigan was the simplest path to power that Uchiha Yansheng could imagine and had the conditions to accomplish.

But unlike the Rinnegan, while the Tenseigan was immensely powerful and possessed a state similar to that of the Sage of Six Paths, along with Truth-Seeking Orbs—

Fundamentally, the Tenseigan should be considered a half-finished product.

After Toneri Otsutsuki was defeated...

No, rather, after that Giant Byakugan was destroyed, the Tenseigan regressed into a Byakugan again. It did not remain permanently in that state like the Rinnegan.

Still, Uchiha Yansheng only wanted power. Those hidden dangers were not important.

He had no intention of stopping there. His future enemies were powerful. At the very least, he needed strength comparable to a Ten-Tails jinchuriki before he could feel somewhat secure.

As for Kaguya Otsutsuki...

As long as Black Zetsu did not stab him through the heart, he should not become Kaguya Otsutsuki's vessel so easily, right?

A mess of thoughts ran through his mind until a faint swelling sensation in his eyes finally brought Uchiha Yansheng back to his senses.

These Byakugan seemed to have already begun evolving.

Over the next month, Uchiha Yansheng waited for the Byakugan to evolve. But after that first flicker of movement, its evolution slowed down.

"Toneri Otsutsuki's Tenseigan evolved very quickly in the story. Was it a matter of talent, or because I'm lacking the chakra of Hamura Otsutsuki's bloodline?"

If it had been before, Uchiha Yansheng might have needed to put in some effort. But now, it was much easier.

After releasing the Spirit Transformation Technique, Uchiha Yansheng returned to his original body.

He glanced at the corpse on the ground and lightly raised his hand. The body identical to his climbed up from the ground like an ordinary person.

Unlike those artificial humans, Uchiha Yansheng had injected a great deal of his own chakra when cloning this body. Therefore, it did not possess the faint soul that all the other clones had.

There was still a slight discomfort, but that was probably caused by the spiritual energy contained within the chakra.

As for the method that allowed this body to stand up, it came from the Tenseigan's puppet-control ability.

Uchiha Yansheng did not understand why his original body had instead gained some new abilities after he had only halfway awakened the Tenseigan in the clone.

Perhaps it was because the hundred thousand Byakugan were sealed inside his body. Since he originally did not possess the Byakugan Kekkei Genkai, he could not activate the power of those hundred thousand Byakugan and could only use them as an enormous chakra reserve.

But now, the potential of those hundred thousand Byakugan had been unlocked?

Without paying attention to such a minor matter, Uchiha Yansheng communicated briefly with the three-meter-tall Little Ten-Tails behind him, then had the body he had cloned gradually merge into the Little Ten-Tails's body.

Immediately afterward, Uchiha Yansheng took out another pair of pure Byakugan and continued his previous work.

After completing everything, joy and conflict intertwined in Uchiha Yansheng's heart as he walked out of the laboratory.

After heading to the location of Cat Ninja Village and chatting with Cat Granny about the latest intelligence, Uchiha Yansheng asked for a map to Sand Village. Then, carrying a massive scroll tall enough to reach half a person's height on his back, he left Cat Ninja Village.

As for the natural energy research plan he had promised Chachamaru...

Next time... next time.

Besides, the place Uchiha Yansheng was going this time was naturally rich in natural energy anyway, so it was not as though he was breaking his promise.

Uchiha Yansheng traveled quickly. Since Sand Village itself was hidden in a sparsely populated desert, he did not draw the gaze of any White Zetsu.

That actually disappointed him somewhat.

The White Zetsu he had captured before were nearly used up. Although he still had some samples remaining, White Zetsu were not truly living beings, and ordinary cloning techniques could not do anything with White Zetsu cells.

Therefore, Uchiha Yansheng had hoped to encounter a few White Zetsu that he could capture.

But it did not matter. It was better that White Zetsu had not discovered his trail. The location he was heading to was somewhere he did not want anyone to know about.

With the Byakugan's powerful observation ability, Uchiha Yansheng soon found his final destination—Loulan.

Of course, it had now become ruins.

In fact, there were many ruins like this in the Ninja World.

For example, the Empty Zone inhabited by the Ninja Cat Clan, the place where Yugito Nii was captured in the original story, and the location of the Gelel Stone were all types of ruins.

This showed that the Ninja World had once been capable of nurturing powerful civilizations.

Unfortunately, under the influence of chakra, an external power, the strength of these native civilizations had become exceedingly fragile and could easily be destroyed.

Though he felt some emotion, Uchiha Yansheng still headed toward the Dragon Vein without hesitation.

Along the way, the Byakugan's penetrating vision allowed him to easily avoid the traps. In the end, he arrived before a Flying Raijin Kunai.

Beneath that Flying Raijin Kunai was the Dragon Vein Seal.

"I wonder whether Naruto Uzumaki traveling back to the past still exists in this world."

Uchiha Yansheng spoke with some emotion, then used his understanding of sealing techniques to open a small gap in the Dragon Vein Seal.

The Dragon Vein's power was extremely formidable. A fully unleashed Dragon Vein could even travel through time and space, so Uchiha Yansheng could not allow something like that to lose control.

Taking down the giant scroll on his back, Uchiha Yansheng released the Little Ten-Tails.

As soon as that massive lump of white matter appeared, it eagerly wriggled toward the Dragon Vein Seal like a mass of white slime.

"Stop!"

Seeing the Little Ten-Tails make such a move for the first time, Uchiha Yansheng's heart stirred, and he suddenly shouted.

Although he could sense the connection between them and his authority over it,

Uchiha Yansheng still wanted to test it and see whether it would disobey his will.

Sure enough, the moment Uchiha Yansheng spoke, the Little Ten-Tails's wriggling body finally stopped.

Then, a yearning consciousness was conveyed to Uchiha Yansheng. It wanted to absorb the power leaking from the Dragon Vein Seal.

"No!"

Uchiha Yansheng refused decisively. Upon receiving the order, the Little Ten-Tails wriggled back to its original position at the same speed and remained perfectly still.
