"A Youkai?" Uchiha Retsu's hand paused in mid-air. "A Youkai? Then... what about that Youkai?"
The woman blinked and looked at him strangely. "You killed it, my lord!" Seeing his brow furrowed in confusion, she carefully described the circumstances of his appearance.
While Yuriko went out to clean up the house destroyed by the Youkai, Uchiha Retsu sat alone in the room, a bit confused about the current situation.
"A Youkai could be some powerful Ninja Beast, but the Sacrifice for Edo Tensei can only be a human, right? Probably?"
Uchiha Retsu said this, though he wasn't sure. After all, if it's a Youkai or something, what if it works?
Uchiha Retsu looked down at his crack-covered hands, his brow furrowed. He was certain this was an Edo Tensei body, but the place he was in now was definitely not the Ninja World he knew.
"Could I have transmigrated again?" he muttered to himself, his voice full of surprise and bewilderment.
He was originally just an ordinary office worker on Earth, but he got lucky after stepping out, and when he woke up, he was in the Naruto World as a boy named Uchiha Retsu from the Uchiha Clan.
The original body he transmigrated into was the same age as Sasuke and was killed during the Night of the Clan Massacre. Since he was too young to have the Sharingan, he wasn't taken away by Root.
He transmigrated and came back to life while the Hokage's Anbu were disposing of the Uchiha Clan members' corpses. Afterward, under the protection of the Third Hokage, he entered the Ninja Academy and successfully graduated to become a Ninja.
Although he had no System or Cheats, he relied on the memories of his past life and the changes brought by transmigration, combined with his body's excellent talent.
Not long after entering the Ninja Academy, he awakened the Sharingan, and two years after graduation, he successfully awakened the Mangekyo Sharingan.
However, he couldn't find a second pair of Mangekyo Sharingan to fuse into the Eternal Mangekyo Sharingan. To prevent blindness from frequent use of the Mangekyo Sharingan...
He secretly sought out Orochimaru and, by providing some secret information from the plot, had Orochimaru help him with Hashirama cells fusion.
Ultimately, using the Ocular Powers of his Mangekyo Sharingan, he successfully fused the Hashirama cells. Not only did he gain Wood Release Ninjutsu, but he also completely resolved the risk of going blind from the Mangekyo.
However, knowing how overpowered the Fourth War was in the plot, he took precautions by creating many Edo Tensei scrolls and hiding them throughout the Ninja World to ensure he could be resurrected through them even after death.
His worries weren't misplaced. After the Fourth Great Ninja War broke out, although he could hold his own against the Edo Tensei Uchiha Madara with his Mangekyo Sharingan...
...when the Ten-Tails appeared and Six Paths Obito and Six Paths Madara showed up one after another, he finally understood what it meant for 'gods to fight while mortals retreat.'
Ultimately, while fighting Six Paths Madara, he died after his heart was pierced. Looking back now, Uchiha Retsu still felt a sense of helplessness; in front of those overpowered powerhouses, his efforts seemed like a joke.
Uchiha Retsu could conclude that he was not in the Ninja World, and the Root of that realization lay in the surrounding Natural Energy.
As a transmigrator familiar with the plot, he naturally did everything he could to learn Senjutsu—an attack method that could not only greatly enhance one's strength but even damage the Ten-Tails Jinchuriki later on.
Just now, when he tried to sense the surrounding Natural Energy to enter Sage Mode, he discovered an anomaly.
The current Natural Energy felt completely different from that of the Ninja World.
Unlike the stillness in the Ninja World, the Natural Energy here was exceptionally active, making it easy to sense and enter Sage Mode. Such a world-level change in energy state was unlikely to occur.
Uchiha Retsu reached out, picked up the scroll in front of him, and examined it carefully. "It really is the Edo Tensei scroll I made."
Unable to figure out the situation, Uchiha Retsu's fingers unconsciously brushed across the paper of the scroll as he pondered with a frown.
"There's one more way to confirm." Uchiha Retsu formed hand seals and slammed his right hand onto the ground.
"Summoning Technique!" A black summoning formula spread across the ground, but no summoned beast appeared at the center.
"I can't sense any contracts..." Uchiha Retsu frowned, looking at the summoning formula before him.
"If this isn't the Naruto World, why is this scroll here?"
He unfurled the scroll, looked at a mark at the end, and after thinking carefully, suddenly remembered something.
In the next second, his black pupils instantly transformed into the crimson Sharingan, the three-tomoe spinning rapidly before finally condensing into the pattern of the Mangekyo.
"Kamui!"
With a low shout, the space around him spiraled and twisted. His body vanished from the room along with the distortion of space, and in the blink of an eye, he entered a murky, gray dimension.
This was the power of Kamui, but it wasn't the Ocular Jutsu of his own Mangekyo Sharingan.
Both of his eyes possessed the ability 'Amenonuhonotama.' It was a powerful ability: as long as he maintained contact with a target and consumed Ocular Power, he could copy their Ocular Jutsu.
Although limited to copying Ocular Jutsu, the copied techniques could be stacked; a newly copied jutsu would not overwrite the previous one, and both the left and right eyes could perform the copy.
Copying required the continuous release of Amenonuhonotama and maintaining contact with the target for a sufficient amount of time. The stronger the Ocular Jutsu, the longer it took, but this time was cumulative.
The Kamui he copied was the ability of Kakashi's Sharingan, which could open a Barrier in his line of sight to teleport away attacks or the enemies themselves within that Barrier, or take himself and others to the other dimension.
Back then, using the excuse of sparring in Taijutsu, he accumulated enough contact time through physical collisions in battle after battle to successfully copy Kakashi's Kamui.
Unfortunately, he never managed to copy Uchiha Obito's right-eye Kamui; Obito's Intangibility always allowed him to evade touch, making it impossible to accumulate even a minute of contact time.
"Still the same as ever." Uchiha Retsu looked at the familiar Kamui Dimension before him and sighed softly.
He walked quickly toward the corner of the stone platform where he remembered placing the scroll, but that spot was empty.
"It's gone, as I thought..." He immediately understood.
"This Edo Tensei scroll fell out of Obito's Kamui Dimension?"
It was possible that after Obito's death, his Kamui Dimension collapsed, causing the scroll to fall into this world; the current Kamui Dimension was a new space regenerated after his own resurrection.
These were all just guesses, but for Uchiha Retsu, being alive was enough. As for whether he had transmigrated again, he no longer cared; after all, it wasn't the first time such a thing had happened.
"It's just this Edo Tensei body that's too much of a hindrance." He clenched his fist, feeling as if his body were encased in a heavy shell.
"I need to find a way to truly resurrect. Although an Edo Tensei body is essentially immortal, it's impossible to exert full strength."
He didn't know if it was because of the different world or the issue with the Edo Tensei Sacrifice, but this body placed significant limitations on his power.
He activated Kamui once more and returned to the room in the blink of an eye.
The room contained only a simple wooden table and bed, without any electrical appliances or similar items.
Through the large hole in the wall, he could see the villagers outside carrying logs to repair the houses, while some were treating the wounded. The air was filled with dust and a faint smell of blood.
From the villagers' clothing and the ugly Chonmage hairstyles of the men, Uchiha Retsu guessed it must be ancient Japan.
This room was originally a storage room in Yuriko's house. When the main house was smashed by the Youkai, one wall of this room was also knocked through, but since the building was still mostly intact, it became the place where he stayed after 'waking up.'
