The Price of X-Ray Vision

After Black Zetsu fled, Danzo Shimura chose to surrender voluntarily.

As for Shisui Uchiha, after several sealing techniques had been placed on him, he collapsed headfirst onto the ground. He had likely passed out.

"Yansheng, are your eyes all right?"

Although Fugaku Uchiha had arrived rather late, he had still clearly witnessed that unbelievable scene and immediately understood that it had been the effect of Izanagi.

As the head of the Uchiha Clan, Fugaku Uchiha certainly did not want a genius of the Uchiha Clan to damage one of his own eyes because of an outsider.

That had been a Mangekyo Sharingan, after all!

Hearing Fugaku Uchiha's question, Uchiha Yansheng quietly opened his palm. Resting there was a lump of white, clay-like matter: replicated Hashirama Cells.

Wrapped within those Hashirama Cells was a Three-Tomoe Sharingan that had lost its light and turned somewhat pale.

Perhaps because of the Hashirama Cells, this Three-Tomoe Sharingan, which had already used Izanagi, had not turned completely white. Instead, faint traces of white tomoe remained.

This method of using the Sharingan as a tool made Fugaku Uchiha's heart tighten as a chain of possible consequences surfaced uncontrollably in his mind.

But when he saw Uchiha Yansheng close his palm again without saying anything, he finally showed a trace of understanding.

That was right. This technique absolutely could not be leaked.

Otherwise, no matter how powerful the Uchiha Clan was, it would become a treasure coveted by the entire Ninja World.

The cleanup naturally fell to the clan head. After examining Kushina Uzumaki's condition, Uchiha Yansheng brought the unconscious Shisui Uchiha back to the laboratory.

Such an opportunity was rare, so Uchiha Yansheng naturally intended to take this chance to study what special changes occurred in the brain of someone who had awakened the Mangekyo Sharingan.

While he was at it, he would check whether any hidden tricks had been left inside Shisui Uchiha's body. It would have been wonderful if he could find a fragment of Black Zetsu for research.

Hmm... the conclusion was that there was no difference at all from an ordinary clan member.

Nor did the Black Zetsu fragment Uchiha Yansheng had hoped for appear. There were only things like curse marks, which should have been easy to remove.

It seemed that the evolution of the Mangekyo Sharingan only caused special changes at that exact instant.

After several hours of work, Uchiha Yansheng deactivated the x-ray vision of his eyes. The instant he shut it off, his vision went black, and he nearly fell over.

At the same time, a sensation of his eye power being both abundant and depleted surged through him.

So using the power of the Byakugan was not without a price. After all, his own eyes were Sharingan. Drawing upon the Byakugan's eye power would naturally affect the Sharingan.

Whether that effect was good or bad, however, was difficult to say.

After all, the origin of the Sharingan was the Byakugan. And who could say how the modern Byakugan differed from that of the Ōtsutsuki Clan?

After resting his eyes for a while, he opened them again, yet that same feeling of abundance and depletion remained.

After recording the specific signs of declining Mangekyo Sharingan vision he had observed on Shisui Uchiha, Uchiha Yansheng went to rest.

By then, the sky had already begun to brighten.

When Uchiha Yansheng woke up, Hiruzen Sarutobi and Kushina Uzumaki had already been waiting outside for a long time.

Their reasons for coming were, first, to tell him Danzo's fate, and second, to deal with the unconscious Shisui Uchiha.

In truth, even without being told, Uchiha Yansheng could guess that Danzo had long been dead. What existed now was merely a remnant produced by Impure World Reincarnation.

Sure enough, Danzo's Impure World Reincarnation was released, and his soul returned to the underworld.

As for Shisui Uchiha...

After being unconscious for some time, Shisui Uchiha had now awakened, though the seals on his body had yet to be removed.

Under the watch of several ninja cats, Shisui Uchiha obediently remained in Uchiha Yansheng's laboratory and was forbidden from touching anything inside.

The moment Shisui Uchiha looked toward somewhere he should not, the ninja cats' claws would rake across him immediately.

Ever since Uchiha Yansheng began researching natural energy, the entire Ninja Cat Clan had become his personal subordinate. They obeyed every one of Uchiha Yansheng's commands without condition.

"Looks like you've recovered quite well."

Without the slightest precaution, Uchiha Yansheng led Hiruzen Sarutobi and Kushina Uzumaki into his laboratory and spoke to Shisui Uchiha, who had not dared move all morning.

The moment he entered the laboratory, Hiruzen Sarutobi quietly surveyed everything within.

Though he saw only the surface of the laboratory, there were death-row prisoners soaking in nutrient solution, Hashirama Cells in the corner, and all sorts of bizarre chunks of flesh floating in the solution...

"Hm? Yansheng, the experimental equipment here is incredibly advanced. It could already serve as top-tier medical equipment."

"If Konoha Hospital had equipment like this, some patients could probably recover several times faster."

Kushina Uzumaki, however, did not care about those test subjects.

Although she was the Nine-Tails' jinchuriki, she was already an adult and understood very well that the Ninja World had never been some glorious fairy-tale world.

"It's very expensive. I doubt that so-called daimyo would allow ninja to spend this much money."

Uchiha Yansheng spoke casually.

That utter lack of respect for the daimyo made Hiruzen Sarutobi frown.

The Ninja World was not a place where strength alone ruled supreme.

Hiruzen Sarutobi wanted to offer a few words of advice, but after considering it for a moment, he ultimately chose to let it go.

"Yansheng, could you make them stop staring at me like that?"

After noticing Uchiha Yansheng, Shisui Uchiha finally raised the head he had kept lowered, revealing a face covered in more than a dozen claw marks.

"Pfft."

Kushina Uzumaki could not hold it in and burst out laughing on the spot.

Shisui Uchiha answered her with a resentful look.

It could not be helped. Kushina Uzumaki's sealing techniques were truly powerful. At that moment, Shisui Uchiha did not have the slightest bit of strength left in his entire body.

Not only could he not use chakra, he could not even use any of the Sharingan's ocular techniques. He had completely become an ordinary person.

And Shisui Uchiha's jonin-level physical condition was simply not worth mentioning before the Ninja Cat Clan, which Uchiha Yansheng had strengthened.

"Sorry, sorry. You were captured by the enemy, after all. Being able to keep your life is already a blessing."

Kushina Uzumaki gave him a reminder, then was about to remove the seals on Shisui Uchiha when she suddenly seemed to recall something and looked toward Uchiha Yansheng.

Uchiha Yansheng did not stop her. He even thoughtfully pointed out several hidden tricks that had been left on Shisui Uchiha.

Very quickly, with the help of Kushina Uzumaki, a master of sealing techniques, Shisui Uchiha successfully regained his original strength.

The instant his strength returned, Shisui Uchiha fled Uchiha Yansheng's laboratory as though escaping for his life.

Of course, he did not go far. He simply did not want to enter that laboratory again.
