Soon, Shusen finished praying.
Unable to wait any longer, Shusen removed the three-tomoe Sharingan from his left eye, then installed the newly fused Mangekyo. He gently swept over it with medical ninjutsu, reconnecting the optic nerve.
After finishing, he blinked. Everything within his field of vision was crystal clear, without the slightest discomfort.
He could not help but marvel at how convenient plug-and-play Sharingan were.
"Next, it's time to explore the Mangekyo's eye techniques."
Shusen took a deep breath and directed chakra toward his left eye.
The instant the chakra fused with his left eye, a strange sensation welled up inside him. The next moment, he understood what eye technique this Mangekyo possessed.
"Not Kamui..."
Shusen was somewhat disappointed. He had already gained a preliminary understanding of the nature of the Mangekyo's technique. It had no physical offensive power whatsoever; instead, it directly affected the mind, invading another person's brain and forcibly rewriting their will...
Wait!
Shusen's eyes widened.
Invading someone else's brain and rewriting their will—wasn't that Shisui's Kotoamatsukami?!
Shusen was at a loss for words. If he had a choice, he did not want this eye technique. He would rather have Tsukuyomi or Amaterasu.
Unfortunately, now that the eye technique had been determined, there was no way to replace it. Unless he could fuse another Mangekyo, there was nothing he could do no matter how unwilling he was.
After pausing for quite a while, Shusen sighed and could only accept reality, continuing to sense the nature of the eye technique.
Time passed, and the disappointment on his face gradually turned strange.
As his understanding of the Mangekyo deepened, he discovered something was off. His eye technique was not the same as Kotoamatsukami.
In the original work, Shisui's Kotoamatsukami could permanently alter another person's will, earning it the title
