Sasuke looked bewildered. "Concentrate it in one eye?!"
"This is only a suggestion."
Hyuga Kagami did not dwell too deeply on the matter.
Whether Sasuke could awaken a single Rinnegan as he had in the original timeline by concentrating the Power of All Creation into one eye was impossible to say. All Hyuga Kagami could do was offer a hypothesis—or rather, an idea. As for whether Sasuke could actually pull it off, that was beyond his control.
"Oh."
Sasuke responded, then fell into thought. He had clearly taken the suggestion to heart.
Before long, Hyuga Kagami finished preparing the fusion fluid and injected it into Sasuke's body.

When it came to researching the First Hokage Cells, he was currently among the very best in the Ninja World. He had not only performed transplant surgeries on Shisui, Itachi, Shinichi, and Karin, but had also completed cell fusion, developed a Yang Release clone containing First Hokage Cells, and created Biological Armor as a byproduct of the Yang Release clone.

"This went even more smoothly than expected." After remarking on it, Hyuga Kagami said to Sasuke on the operating table, "The surgery is complete. Rest here for a while. Once
