Planning for the Dragon Vein's Power

"As expected, the Spirit Transformation Technique is not the Living Corpse Reincarnation. Although I can occupy this body, it is not a true replacement; I can still sense the existence of my original body."

"Even with this special, soulless clone, I can feel a slight rejection. Is it because of the presence of Chakra?"

"Confirmed: the Spirit Transformation Technique should have a time limit, but if the amount of Chakra carried by the soul increases, the duration of the technique should increase accordingly."

"What if the Chakra is exhausted?"

Ensei Uchiha controlled the consumption of his Chakra. Soon after it was depleted, he could feel his original body summoning his soul, along with a subtle sense of discomfort emanating from within the clone.

Immediately following this, two forces of attraction appeared simultaneously, as if demanding that Ensei Uchiha make a choice.

However, Ensei Uchiha could sense that if he continued to remain in this body, while he could achieve results similar to possession, this body would likely develop a rejection of his soul after a period of time.

In the Shinobi World, this phenomenon is difficult to describe.

But based on the memories of Ensei Uchiha's past life, this was clearly a case of incompatibility between soul and flesh; he only needed to find a way to increase the fusion between the two.

Ignoring it would also work; he would simply need to change bodies every few years.

Spirit Transformation Technique + some secret soul-devouring art—is that essentially the Living Corpse Reincarnation?

Ensei Uchiha guessed wildly without the slightest concern; it didn't matter if he was wrong anyway.

After all, his current actions had already achieved an effect similar to the Living Corpse Reincarnation, and it was one he could withdraw from at any time without damaging his own soul.

But in the short term, there was no need for Ensei Uchiha to abandon his original body, so after a brief trial, he returned to his true form.

Afterward, Ensei Uchiha performed the Spirit Transformation Technique again, carefully analyzing the data of this clone.

After moving his body slightly, Ensei Uchiha activated the power of his Byakugan, and sure enough, veins bulged on both sides of his eyes.

It could be confirmed: the reason he could previously use the Byakugan without warning was that the Byakugan within his body were bearing the pressure of activation.

And now...

Ensei Uchiha stared at his original body for a long while, placed his palm over the Eight Trigrams Seal on his stomach, and drew upon the ocular power of the Byakugan from within the seal to nourish his eyes.

In the original work, the Tenseigan was the most accessible path to power that Ensei Uchiha could imagine and potentially complete.

But unlike the Rinnegan, although the Tenseigan is powerful and possesses a state similar to the Sage of Six Paths as well as Truth-Seeking Orbs, it is essentially a semi-finished product.

After Otsutsuki Toneri was defeated...

No, it should be said that after that Giant Byakugan was destroyed, the Tenseigan regressed back into a Byakugan; it did not maintain a permanent state like the Rinnegan.

However, Ensei Uchiha only cared about power; those hidden dangers were unimportant.

He had no intention of stopping here. Future enemies would be very strong; he needed to master at least the strength equivalent to a Ten-Tails Jinchuriki to feel any sense of security.

As for the issue of Kaguya Otsutsuki...

If he didn't get his heart stabbed by Black Zetsu, he shouldn't easily become a vessel for Kaguya Otsutsuki, right?

His mind was filled with a chaotic mess of thoughts until a slight swelling sensation in his eyes brought Ensei Uchiha back to his senses.

These Byakugan seemed to have already begun to evolve.

Over the next month, Ensei Uchiha waited for the Byakugan to evolve, but since that first movement, the speed of the evolution had slowed down.

"In the story, the speed at which Otsutsuki Toneri evolved the Tenseigan was very fast. Is it a matter of talent, or is it because of the lack of Chakra from the lineage of Hamura Otsutsuki?"

If it were before, Ensei Uchiha might have had to expend some effort, but now it was much simpler.

After dispelling the Spirit Transformation Technique, Ensei Uchiha returned to his original body.

Glancing at the corpse on the ground, Ensei Uchiha raised his hand slightly, and that body, identical to his own, climbed up from the floor like a normal person.

Unlike those Artificial Humans, Ensei Uchiha had injected a great deal of his own Chakra when cloning this body, so there was no faint soul present as there was in other clones.

Although there was still a slight sense of discomfort, this was likely due to the mental energy contained within the Chakra.

As for the method of making this body stand, it originated from the puppet control abilities of the Tenseigan.

Ensei Uchiha did not understand the principle of why his original body gained new power while he was halfway through activating the Tenseigan for the clone.

Perhaps it was because those 100,000 Byakugan were sealed within his body; he originally lacked the Byakugan Kekkei Genkai, so he couldn't activate the power of the 100,000 Byakugan and could only use them as a massive Chakra battery.

And now, the potential of the 100,000 Byakugan had been unlocked?

Ignoring this trivial matter, Ensei Uchiha communicated for a moment with the three-meter-tall Mini Ten-Tails behind him, then allowed this cloned body to gradually merge into the body of the Mini Ten-Tails.

Following this, Ensei Uchiha took out another pair of pure Byakugan and continued his previous actions.

After completing everything, Ensei Uchiha, his heart a mix of joy and hesitation, walked out of the laboratory.

He went to the location of the Cat Ninja Village, chatted with Granny Cat about the latest intelligence, requested a map of Sunagakure, and then left the village with a giant scroll half a person's height strapped to his back.

As for the Natural Energy research project he had promised Chachamaru...

Next time... he would talk about it next time!

Besides, the place Ensei Uchiha was heading to already contained rich Natural Energy, so he wasn't exactly breaking his word.

Ensei Uchiha traveled at a high speed, and since Sunagakure was hidden in a sparsely populated desert, he did not attract the prying eyes of any White Zetsu.

This situation left him feeling somewhat disappointed.

The White Zetsu captured previously had been mostly consumed; although a few samples remained, White Zetsu were not truly living beings, and ordinary cloning technology had no effect on their cells.

Therefore, Ensei Uchiha still very much hoped to encounter a few White Zetsu to capture.

But it did not matter; it was better not to have his tracks discovered by White Zetsu, as Ensei Uchiha did not want anyone to know the specific location or his movements regarding the place he was heading to.

Under the powerful observational capabilities of the Byakugan, Ensei Uchiha soon found his ultimate destination—Rōran.

Of course, it had already become a ruin by now.

In fact, there were many such ruins in the Shinobi World.

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

From this, it could be seen that the Shinobi World was also capable of giving birth to powerful civilizations.

It was just a pity that the power of these indigenous worlds became fragile and easily destroyed under the influence of an external force like Chakra.

With a sigh in his heart, Ensei Uchiha still moved forward toward the location of the Dragon Vein without hesitation.

Along the way, the clairvoyant ability of his Byakugan allowed him to easily avoid traps, eventually bringing him before a Flying Thunder God kunai.

And beneath that Flying Thunder God kunai lay the seal of the Dragon Vein.

"I wonder if the plot point of Naruto returning to the past still exists in this world."

Ensei Uchiha spoke with some emotion, then relied on his own understanding of sealing techniques to open a small gap in the Dragon Vein seal.

One had to know that the power of the Dragon Vein was immense; a fully unleashed Dragon Vein could even traverse time and space, and Ensei Uchiha could not allow such a thing to spiral out of control.

Taking the giant scroll from his back, Ensei Uchiha released the Mini Ten-Tails.

After that massive lump of white substance appeared, it crawled impatiently toward the location of the Dragon Vein seal, looking exactly like a white slime.

"Stop!"

Watching the Mini Ten-Tails act in such a way for the first time, Ensei Uchiha's heart stirred, and he suddenly shouted.

Although he could perceive the connection between himself and the creature, as well as his authority to command it, Ensei Uchiha still wanted to test whether it would defy his will.

Sure enough, the moment Ensei Uchiha spoke, the wriggling body of the Mini Ten-Tails finally came to a halt.

Immediately afterward, a sense of longing was fed back to Ensei Uchiha; it wanted to absorb the power leaking from the Dragon Vein seal.

"No!"

Ensei Uchiha refused quite decisively, and upon receiving the order, the Mini Ten-Tails crawled back to its original position at the same speed and remained motionless.
