Tenseigan Successfully Synthesized

Watching the Little Ten-Tails behave so obediently, Uchiha Yansheng still had some reservations, but at this moment, he did not have much right to question it.

After instructing the Little Ten-Tails to stay put, Uchiha Yansheng began setting up barriers throughout the underground space and leaving Flying Raijin marks in concealed corners.

The process of setting up the barriers was lengthy. Uchiha Yansheng's sealing skills were fairly good, but compared to Kushina Uzumaki, he still fell far short.

Moreover, barriers generally required many sealing ninja to set them up together.

Uchiha Yansheng was alone, and his standards for the barriers were high, so the slow progress was only natural.

Once the barriers had been completed, Uchiha Yansheng took out four artificial Human Puppets.

At present, the bodies of Numbers One, Two, and Three had each been sealed with a portion of Tailed Beast chakra. Although it was not much, it was more than enough for them to briefly fend off enemies at a critical moment.

And even if they were outmatched, they could join forces with Number Four to cast the Four Crimson Yang Formation.

This technique could withstand even the Tailed Beast Bombs of ten tailed beasts. Holding off enemies for a while would definitely not be a problem.

Next, Uchiha Yansheng arranged several other measures, such as Exploding Flies, Patrick Star, and technological items like explosives.

By the time he finished everything, three days had passed.

During that time, the Little Ten-Tails had remained obediently where it was. Other than conveying its hunger whenever Uchiha Yansheng approached, it made no other movements.

After some thought, Uchiha Yansheng had the Little Ten-Tails separate off a small piece, which he then sealed away.

Afterward, he carved several hundred Flying Raijin marks onto the Little Ten-Tails and buried a Flying Raijin kunai inside its body.

Only then did Uchiha Yansheng allow the Little Ten-Tails to absorb the natural energy within this space.

Since the Dragon Vein Seal had been leaking for three days, the natural energy here had naturally become extremely abundant. Yet before Uchiha Yansheng gave the order, the Little Ten-Tails had still not chosen to feed.

Judging from that alone, the Little Ten-Tails should have been trustworthy.

However, Uchiha Yansheng believed that he still needed to remain as vigilant as possible.

Another two days passed, and the food Uchiha Yansheng carried with him was nearly exhausted. He therefore used Flying Raijin to replenish his supplies in a town somewhere within the Land of Fire.

Out of caution, Uchiha Yansheng activated the Byakugan's penetrating vision and discovered several White Zetsu hiding beneath the town.

What a stroke of luck!

Uchiha Yansheng was overjoyed, but he pretended to know nothing and left the town.

Only after the White Zetsu came within roughly a hundred meters of him did he pretend to notice them and capture one in a single move.

After one White Zetsu was caught, the others hurriedly fled.

Just when Uchiha Yansheng thought that one White Zetsu would be his only gain for the day, another White Zetsu suddenly approached to within about a hundred meters.

This behavior was obviously a test.

Uchiha Yansheng did not hesitate and immediately made his move, capturing another one.

Then, as though he had suddenly thought of something, he began moving rapidly through the area. Whenever a White Zetsu came within a hundred meters of him, he captured it directly.

After he caught two in a row, the remaining White Zetsu finally burrowed more than a hundred meters underground.

After circling the area twice and failing to "discover" any more White Zetsu, Uchiha Yansheng decisively used Flying Raijin to return to the laboratory located within the Uchiha Clan.

The laboratory's equipment was still there, but the traces of it having been searched were glaringly obvious, as though there had been no intention of concealing them at all.

Konoha's people? How interesting.

After placing the scroll that sealed the White Zetsu in a hidden compartment, Uchiha Yansheng did not hesitate in the slightest before using Flying Raijin to arrive at a concealed corner along the border between the Land of Fire and the Land of Lightning.

Only then did he use Flying Raijin again to return to the Loulan Ruins.

After observing for several days, Uchiha Yansheng finally ordered the Little Ten-Tails to head to the location of the Dragon Vein Seal.

He also instructed it not to damage the Dragon Vein Seal and only to absorb the natural energy leaking from it.

Then, Uchiha Yansheng tossed two cloned bodies containing Byakugan and Hyuga Clan bloodlines into the Little Ten-Tails, allowing it to cultivate them in a targeted manner.

Over the following period, Uchiha Yansheng extracted a large amount of ocular power every day from the hundred thousand Byakugan within the Eight Trigrams Seal in his body to nurture the clones inside the Little Ten-Tails.

Sure enough, with the Little Ten-Tails' help, the Tenseigan's gestation progress sped up considerably.

Finally, after several months, the third gestation cycle ended, and the power of the Tenseigan finally emerged.

Unable to wait any longer, Uchiha Yansheng used the Spirit Transformation Technique and chose one body to enter. There was a slight discomfort at first, but he soon felt a wave of soothing comfort.

At that moment, it felt as though his entire soul had been cleansed.

After Uchiha Yansheng tested it, that indeed seemed to be the case. His spiritual energy had suddenly increased by a great deal, likely due to feedback from this body.

Next, Uchiha Yansheng tried the second body.

This time, there were no other changes. He merely felt that his adaptability to the body had grown stronger.

For the next stretch of time, Uchiha Yansheng began testing the Tenseigan's abilities and the limits of its combat power.

In terms of power level, it had definitely reached the level of the Rinnegan. In some respects, it even surpassed it, such as its ability to condense Truth-Seeking Orbs.

However, compared with the Rinnegan, the Tenseigan seemed somewhat lacking in endurance. If used in an all-out battle, it could only be sustained for a relatively short time.

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

Measured in chakra, it was probably equivalent to the chakra of half an Eight-Tails.

If the Tenseigan's chakra was depleted, it needed to draw power from the Byakugan sealed within Uchiha Yansheng's body, or absorb external chakra to replenish itself.

In other words, the Tenseigan did not possess the ability to restore its own power.

Like the Rinnegan, the Tenseigan could absorb chakra, and it did not even require physical contact. It only needed to be within a certain range.

As a weapon at this stage, the Tenseigan had many flaws, but purely in terms of combat strength, it was undoubtedly qualified.

At the same time, Uchiha Yansheng tested the limits of the Spirit Transformation Technique and discovered that as long as he carried enough chakra, it would not be a problem even if he did not return to his original body for several months.

But Uchiha Yansheng would not abandon his original body. This was merely a temporary measure.

Incidentally, he planned to have the Little Ten-Tails comprehensively cultivate his body. If possible, it would be best for it to gain the Ōtsutsuki Clan's greatest talents.

After conveying his thoughts to the Little Ten-Tails, Uchiha Yansheng watched as it gradually swallowed his body.

After thinking it over, Uchiha Yansheng still tossed those two Mangekyo Sharingan into it as well.

Rather than eyes that would awaken unknown abilities, he would prefer Kamui and Kotoamatsukami. As for whether it would succeed, that depended on luck.

He dispelled the Spirit Transformation Technique and returned to his original body once, feeling what it was like inside the Little Ten-Tails. Only then did Uchiha Yansheng use the Spirit Transformation Technique again and enter the clone.

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

After placing the other body with the Tenseigan inside the Little Ten-Tails as well, Uchiha Yansheng gave it one last reluctant look before finally deciding to return to Konoha.
