Tenseigan Successfully Synthesized

Looking at the Mini Ten-Tails' obedient appearance, Ensei Uchiha still harbored some concerns, but at this moment, he did not have the luxury of questioning it too much.

Ordering the Mini Ten-Tails to stay put, Ensei Uchiha began setting up barriers throughout this underground space and leaving Flying Thunder God Kunai marks in various hidden corners.

The process of setting up barriers was long; while Ensei Uchiha's sealing jutsu level was decent, it was still far inferior to Kushina Uzumaki's.

Furthermore, barriers generally required multiple sealing ninjas to set up together.

Since Ensei Uchiha was alone and had very high standards for the barriers he constructed, it was only natural that progress was a bit slow.

Once the barriers were completed, Ensei Uchiha took out four Artificial Human puppets.

Currently, the bodies of No. 1, No. 2, and No. 3 had already been sealed with a portion of Tailed Beast Chakra; although it wasn't much, it was perfectly sufficient for dealing with enemies in a pinch.

Moreover, even if they were outmatched, they could combine with No. 4 to cast the Four Red Yang Formation.

This technique could even withstand a Tailed Beast Bomb from a Ten-Tails, so it would certainly have no trouble holding off enemies for a period of time.

Following this, Ensei Uchiha set up other measures, such as Self-Destruct Flies, Patrick Stars, and some technological items like explosives.

After finishing all these tasks, three days had passed.

During this period, the Mini Ten-Tails remained obediently in place, showing no movement other than expressing a sense of hunger whenever Ensei Uchiha approached.

Ensei Uchiha thought for a moment, had the Mini Ten-Tails separate a small piece of itself, and then sealed it away.

Afterward, he carved hundreds of Flying Thunder God marks onto the Mini Ten-Tails and buried a Flying Thunder God Kunai inside its body.

Only then did Ensei Uchiha allow the Mini Ten-Tails to absorb the Natural Energy in this space.

Because the Dragon Vein seal had been leaking for three days, the Natural Energy here had naturally become very abundant, but the Mini Ten-Tails did not choose to consume it until Ensei Uchiha gave the order.

From this perspective, the Mini Ten-Tails seemed trustworthy.

However, Ensei Uchiha believed he still needed to maintain the utmost vigilance.

Two more days passed, and the food Ensei Uchiha had brought with him was nearly exhausted, so he used the Flying Thunder God to go to a town in the Land of Fire to replenish his supplies.

Out of caution, Ensei Uchiha activated his Byakugan's X-ray vision and discovered several White Zetsu lurking beneath the town.

What a stroke of luck to find them without even trying!

Ensei Uchiha was ecstatic inside, but he acted as if he knew nothing and left the town.

Once the White Zetsu were within a range of about 100 meters, he feigned discovery and captured one in a single stroke.

After one White Zetsu was caught, the remaining ones fled in a hurry.

Just as Ensei Uchiha thought he would only have one White Zetsu to show for the day, more White Zetsu suddenly approached within a 100-meter range.

This behavior was clearly a test.

Ensei Uchiha did not hesitate and immediately moved to capture another.

Following that, as if struck by a sudden thought, he moved rapidly through the vicinity, capturing every White Zetsu that entered within 100 meters of him.

After catching two in this manner, the remaining White Zetsu dove deep into the ground, beyond the 100-meter range.

After wandering around twice more and failing to "discover" any more White Zetsu, Ensei Uchiha decisively used the Flying Thunder God to return to the Uchiha Clan's research lab.

At this moment, although the various equipment in the lab was still there, the traces of it having been searched were glaringly obvious, as if there had been no intention to cover them up at all.

Konoha people? How interesting.

After placing the scroll containing the captured White Zetsu into a hidden compartment, Ensei Uchiha did not hesitate to use the Flying Thunder God to reach a hidden corner on the border between the Land of Fire and the Land of Lightning.

Only then did he use the Flying Thunder God again to return to the Rōran Ruins.

After observing for a few more days, Ensei Uchiha finally ordered the Mini Ten-Tails to head to the location of the Dragon Vein seal.

He instructed it not to destroy the Dragon Vein seal, but only to absorb the Natural Energy leaking from it.

Subsequently, Ensei Uchiha threw two cloned bodies, containing the Byakugan and the bloodline of the Hyuga Clan, into the Mini Ten-Tails' body, letting it perform targeted cultivation.

In the time that followed, Ensei Uchiha extracted a massive amount of ocular power every day from the 100,000 Byakugan sealed within his Eight Trigrams Seal to nurture the clones inside the Mini Ten-Tails.

Sure enough, with the help of the Mini Ten-Tails, the progress of the Tenseigan's fetal movement accelerated significantly.

Finally, after a few months, the third fetal movement concluded, and the power belonging to the Tenseigan finally emerged.

Unable to wait, Ensei Uchiha used the Spirit Transformation Technique to enter one of the bodies; there was slight discomfort at first, but soon Ensei Uchiha felt a wave of refreshment.

At this moment, it felt as if his entire soul had been cleansed.

After Ensei Uchiha tested it, it seemed that was indeed the case, as his mental energy had suddenly increased by a large margin, likely due to the feedback from this body.

Immediately after, Ensei Uchiha tried the second body.

This time, there were no other changes, only a feeling that his adaptability to the body had become stronger.

In the following period, Ensei Uchiha began to test the abilities of the Tenseigan and his combat limits.

In terms of power level, it had certainly reached the level of the Rinnegan, and in some aspects, it even surpassed it, such as the ability to condense Truth-Seeking Orbs.

However, compared to the Rinnegan, the Tenseigan seemed to lack stamina; if he fought at full strength, the duration was relatively short.

Of course, the short duration was only relative to the Rinnegan.

If quantified by Chakra, it was roughly equivalent to the Chakra of half an Eight-Tails.

If the Chakra of the Tenseigan were to be exhausted, it would need to draw power from the Byakugan sealed within Ensei Uchiha's body, or otherwise absorb external Chakra as a supplement.

Hmm, the Tenseigan does not possess the ability to self-recover its power.

Much like the Rinnegan, the Tenseigan possesses the power to absorb Chakra, and it does not even require physical contact; it only needs to be within a certain range.

As a weapon at the current stage, even though the Tenseigan has many shortcomings, it is undoubtedly qualified when viewed solely from the perspective of combat power.

At the same time, Ensei Uchiha tested the limits of the Spirit Transformation Technique and discovered that as long as he carried enough Chakra, it would be no problem to remain away from his original body for even several months.

However, Ensei Uchiha would never abandon his original body; this was merely an expedient measure for now.

Incidentally, he prepared to have the Mini Ten-Tails conduct a comprehensive cultivation of his body, and if possible, he wanted his body to possess the peak talent of the Otsutsuki Clan.

After conveying his thoughts to the Mini Ten-Tails, Ensei Uchiha watched as it gradually swallowed his body bit by bit.

After thinking it over, Ensei Uchiha decided to toss those two Mangekyo Sharingan in as well.

Rather than awakening eyes with unknown abilities, it was better to choose Kamui and Kotoamatsukami, though whether it would succeed would depend on luck.

He dispelled the Spirit Transformation Technique to return to his original body once, and after sensing the feeling of being inside the Mini Ten-Tails, Ensei Uchiha cast the Spirit Transformation Technique again to enter the Clone Body.

For the next few years, he would likely be using this body.

After placing the other body possessing the Tenseigan into the Mini Ten-Tails as well, Ensei Uchiha took one last lingering look before finally deciding to return to Konoha.
