Uchiha Setsuna looked at himself in the mirror as his two Sharingan slowly spun.
One had three tomoe, while the other was a Mangekyō Sharingan.
Inside the container beside him, one Mangekyō Sharingan had already lost its color and turned somewhat pale. It had clearly lost all vitality and ocular power.
"In the original story, Uchiha Shin possessed Mangekyō Sharingan and numerous clones, yet he still failed to fuse an Eternal Mangekyo Sharingan."
"And it remained an ordinary Mangekyō."
"Orochimaru knew of the Eternal Mangekyo's existence. There was no way he had never conducted an experiment like this."
Uchiha Setsuna looked at his reflection, his expression somewhat strange.
"And this time, I..."
"Failed."
"But I could also say I succeeded."
Uchiha Setsuna recalled what had just happened.
He had first transplanted one Mangekyō Sharingan into his eye socket, then used Chakra to guide it into absorbing the ocular power of the other Mangekyō Sharingan.
The ocular power of the other Mangekyō Sharingan had indeed been absorbed.
In other words, the two Mangekyō Sharingan had truly fused completely.
But what resulted was not an Eternal Mangekyo.
"Maybe it would be more fitting to call it a Critical Mangekyo."
"The fusion of two Mangekyō strengthened the Mangekyō. Put differently, the Kamui I used would be more powerful, equivalent to a ninjutsu amplification."
"But it also has a drawback."
"Still, that drawback does not affect me much."
The drawback of the Critical Mangekyo was that its side effects were somewhat greater, but Uchiha Setsuna had fused Hashirama Cells.
With Hashirama Cells, that slight increase in side effects did not have much of an impact on Uchiha Setsuna.
However, the increase in power provided by the Critical Mangekyo was extremely useful to Uchiha Setsuna.
Uchiha Setsuna was at the Kage level.
Even among those
