Farewell

The power increase granted by the Mangekyō Sharingan was directly tied to how often and how frequently it was used.

But this would inflict permanent damage on any Mangekyō Sharingan that had not reached the Eternal Mangekyō Sharingan. It was a difficult choice.

If one wanted to grow stronger, one had to accept the fate of gradually going blind.

For shinobi who relied on the Sharingan, that was simply too cruel.

The only solution was to transplant the ocular power of another Mangekyō Sharingan of the same kind.

For the time being, Mizuki did not have to worry about chakra depletion like Hatake Kakashi did.

However, whether it was Uchiha Obito or Itachi Uchiha, reaching the level where they could use the Perfect Susanoo was not something that could be achieved in a year or two.

But the remaining three pairs of Mangekyō Sharingan did not come from closely related brothers. Mizuki could only hope that transplanting Mangekyō Sharingan between distant relatives would work as theorized.

"If the Shinobi World remains limited by its original upper limit of power, let alone sealing Kaguya Otsutsuki, it may not even have the strength to resist. Even the First Hokage, Hashirama Senju, who possessed the Eternal Mangekyō Sharingan and Wood Release Sage Art, would find it difficult to play a decisive role—and they were already powerhouses hailed as the 'God of Shinobi.' If we do not expand the upper limit of power and create a group of strong individuals, the Shinobi World may truly have no hope."
