After Uchiha Shūichi finished speaking, the meeting hall fell completely silent. Uchiha Fugaku looked distinctly uncomfortable as he spoke coldly:
"Even without help from the other ninja clans, so what? The Uchiha Clan alone is strong enough to stand against Konoha's leadership!"
"Itachi awakened the Mangekyō Sharingan. There isn't a single shinobi in all of Konoha Village who can stand against the Mangekyō Sharingan now!"
Uchiha Shūichi narrowed his eyes slightly and glanced at Uchiha Fugaku. Unlike the reluctant, halfhearted way he'd acted in the original story, the man now seemed genuinely intent on leading the Uchiha in a coup.
But after thinking it over, Uchiha Shūichi understood why. In the original story, Uchiha Fugaku knew only that he had awakened the Mangekyō; he didn't know that his son had awakened it too, and he also didn't know about Uchiha Shisui's Kotoamatsukami.
Now, although Uchiha Fugaku still didn't know about Kotoamatsukami, he knew that his son had awakened the Mangekyō. The power of two Mangekyō Sharingan together was already enough to stand against Konoha Village.
It wouldn't even matter if he or Uchiha Itachi died. The bond between father and son was no weaker than that between brothers; perhaps the two pairs of Mangekyō could be combined into a single Eternal Eye.
The difference between the Mangekyō and the Eternal Mangekyō wasn't just that using the latter didn't damage the eyes!
In fact, after awakening the Eternal Mangekyō, an Uchiha's Chakra reserves, Yin Release mastery, and Dojutsu Power all increased dramatically. The power of the Mangekyō Sharingan's Dojutsu also underwent a complete transformation.
Put simply, shinobi who awakened the Mangekyō Sharingan were generally among the strongest at Kage Level. Once the Mangekyō evolved into the Eternal Mangekyō, they'd more or less reached the threshold of Super Kage Level.
With that
