The state of what appeared to be the Mangekyo Sharingan suddenly regressed to the image of a Three Tomoe Sharingan; at first glance, it seemed as though the strength of Ensei Uchiha had diminished.
But in reality, the combat power of Ensei Uchiha had become even stronger, and his control over the one hundred thousand Byakugan pupils sealed within his body had also improved.
The most intuitive manifestation of this was that Ensei Uchiha now possessed a perspective ability similar to that of the Byakugan.
Moreover, it was not black and white, but in full color.
No, using "color" to describe it might be slightly inappropriate; perhaps it should be said that he could perceive the inherent colors of things themselves?
As for seeing through the human body... it wasn't exactly intelligent; he had to manually distinguish the layers of clothing he wanted to peer through. Unless someone was wearing only a single layer, he shouldn't be able to see them naked.
The Hyuga Clan—it was no wonder they used such harsh clan rules to restrict their members. This likely involved not only the issue of their Byakugan being gouged out, but also the need to prevent their own people from inciting hostility from the outside world.
That Neji in the Infinite Tsukuyomi wasn't beaten to death—it really was just because Konoha was too peaceful!
"Ensei? What's wrong?"
Kushina Uzumaki watched as Ensei Uchiha stared at her in a daze once again, and she felt that the whole situation was a bit strange.
"Uh... nothing, it's just that I didn't expect modifying the seal would cause such a massive change to my body."
Ensei Uchiha offered a simple, perfunctory excuse, then continued to ask Kushina Uzumaki for knowledge regarding the Flying Thunder God.
Fortunately, when he activated this perspective ability, the veins around his eyes did not bulge.
Come to think of it, even the Otsutsuki Clan would have bulging veins around their eyes when using the Byakugan to see through things, and they were unable to maintain it for long.
Yet he, for some reason, did not have this trait, and maintaining it didn't seem to put much pressure on him.
Could it be that all this pressure had been transferred to the one hundred thousand Byakugan sealed within his body?
Ensei Uchiha felt a surge of excitement. Although he instinctively felt that this was merely his own conjecture, the fact that this state had appeared for the first time made him unable to stop his mind from racing with more ideas.
One had to know, if by any chance it were true.
This would be a feat that surpassed the Otsutsuki Clan!
Kushina Uzumaki, who was speaking at his side, noticed that Ensei Uchiha had drifted off again, and she immediately understood that today was indeed not the right time to continue the lesson.
"Ensei, don't be too impatient when learning sealing techniques, especially when it comes to unknown ones. Do not try to touch them, as it is very easy to cause a major disaster."
"Let's stop here for today. You should go and adapt to the Eight Trigrams Seal within your body first. If you have any other questions, you can come find me at any time."
Hearing Kushina Uzumaki's words, Ensei Uchiha knew she was right. Furthermore, he truly had many experiments he wanted to try, so he chose to take his leave in a very crisp and decisive manner.
Before leaving, Ensei Uchiha happened to run into Naruto Uzumaki, who had just returned from the Ninja Academy. After a brief greeting, he prepared to depart.
But after walking a short distance, the sound of Naruto Uzumaki complaining to Kushina about trivial matters at the Ninja Academy drifted into his ears.
For some reason, Ensei Uchiha's mood suddenly became much lighter, and the pressure that had been echoing in his heart all this time quietly dissipated at this moment.
"Peace, huh? It actually seems quite nice."
Just as Ensei Uchiha was rewriting the seal within his body, inside an abandoned laboratory of the Root in Konoha, a figure was frantically practicing something.
In front of him, besides a Kirigakure ninja who had already fallen unconscious, there lay a small piece of flesh that had already begun to rot.
"Impure World Reincarnation Jutsu..."
Finally, after countless attempts, this loyal follower of Danzō finally succeeded in casting the Impure World Reincarnation Jutsu.
Countless specks of dust rose from the ground, enveloping the unconscious Kirigakure ninja.
Even though he was in a state of deep unconsciousness, the Kirigakure ninja still let out a shrill, miserable scream at this very moment.
It was a pity that this was the lowest level of the Root base, and since the base had long been abandoned, it was impossible for anyone to notice what was happening here.
If you can't find the book title, you can try searching for the author; perhaps it just changed its name!
Before long, the figure of Shimura Danzō finally replaced the original Kirigakure ninja.
Opening his eyes, Shimura Danzō understood the current situation in an instant.
"Impure World Reincarnation, is it? Well done, Shingaraki."
Feeling the power he now possessed, Shimura Danzō suddenly reached out without warning and gripped Shingaraki's throat tightly.
"I am very grateful for your contribution. Konoha will remember you."
As Shimura Danzō exerted force with his palm, Shingaraki, the only loyal follower still devoted to Danzō, died just like that at his hands.
Looking at the dead body of Shingaraki, the eyes of the reanimated Shimura Danzō were filled with an indescribable complexity.
"I'm sorry, the caster being the only flaw of the Impure World Reincarnation is unavoidable. For the sake of Konoha, I have no choice but to do this."
"That Monkey is too soft-hearted. If it weren't for me, Konoha would surely..."
In the dark, abandoned base, the voice of Shimura Danzō, filled with guilt, echoed.
Not long after, Shimura Danzō toured the abandoned base alone and felt his own power, discovering that it had declined severely, to only one-third of what it was in his lifetime, if not less.
He felt a bit disappointed in his heart, but he quickly adapted to it. Afterward, Shimura Danzō hid in the shadows and quietly observed Konoha.
When he discovered that Konoha was just as it had always been, an indescribable sense of grievance welled up in his heart.
But in an instant, the gaze of Shimura Danzō became firm once again.
Next, Shimura Danzō began to summon some of the old members of the Root.
However, because Hiruzen Sarutobi had disbanded the members of Root and reintegrated them into various parts of Konoha, only a small fraction of the die-hard loyalists could be found by Shimura Danzō.
After learning the situation from these gathered former subordinates, the fury in Shimura Danzō's eyes could no longer be concealed.
Yet for some reason, he did not act immediately; instead, he quietly went to Hiruzen Sarutobi's residence and sought him out.
"Danzō... aren't you dead?"
Upon seeing Shimura Danzō's figure, Hiruzen Sarutobi was momentarily stunned, but he quickly realized that these were the eyes characteristic of Impure World Reincarnation.
"Impure World Reincarnation, how could you..."
The reason he remembered these eyes was that he, too, had once researched Impure World Reincarnation during Konoha's most difficult times.
But in the end, Hiruzen Sarutobi had given it up.
He just never expected that the forbidden jutsu he had abandoned would actually be used on himself by Danzō.
Although records of Impure World Reincarnation existed only in Konoha, Hiruzen Sarutobi still prepared himself to fight at any moment.
As an old partner who had worked alongside Hiruzen Sarutobi for decades, Shimura Danzō naturally understood what Hiruzen Sarutobi was thinking at this moment.
"Don't worry, Monkey. I am not being controlled by anyone; the person who brought me back with Impure World Reincarnation is already dead."
Following Shimura Danzō's explanation, Hiruzen Sarutobi became even more tense.
"What exactly have you done? Explain it to me clearly!"
Afraid of waking Biwako, who was sleeping, Hiruzen Sarutobi's voice was very low, yet it was laced with intense anger.
Seeing that Hiruzen Sarutobi was truly angry, Shimura Danzō quite straightforwardly told him everything he had done.
Following the normal course of events, Hiruzen Sarutobi would have been unable to listen halfway through and would have told Shimura Danzō to handle it himself.
But now... there was no choice; Danzō was already dead, and he could not be allowed to act recklessly any longer.
Who knew what might change now that he was dead?
