Sasuke's expression darkened as Indra spoke, like the sky before a storm.
The Mangekyo Sharingan's ocular power was inferior to the eternal Mangekyō Sharingan's. He had already noticed that discrepancy.
But at the time, his attention had been almost entirely drawn to the apparent fact that "Black Zetsu was controlling Itachi." Driven by the urge for revenge, he had neglected to examine his surroundings more deeply and failed to immediately see through the high-level genjutsu enveloping him.
And by the time he belatedly realized something was wrong and his eternal Mangekyō Sharingan began breaking through the illusion on its own... Itachi had already dispelled the encompassing genjutsu himself.
It seemed the initiative had never been in his hands to begin with.
"Now that you're back in reality, you should have calmed down."
Indra's voice sounded in Sasuke's mind.
"As a practitioner of ninshu..."
Indra seemed to feel a flicker of nostalgia for that ancient term, which then turned into a barely audible scoff. "Heh. You call yourselves ninja now, don't you?"
"Whatever the name, the essence remains the same. As a ninja who pursues power and engages in combat..."
Indra's voice abruptly grew stern. "You must remain absolutely calm when you fight.
Your emotions can only serve as fuel. They must never become a fog that blinds you, much less the reins that control your actions.
A ninja ruled by emotion, however powerful, is nothing more than a beast. Sooner or later, he will fall into a trap laid by a calmer hunter.
Just now, you nearly became a mindless beast."
"If you want revenge, now is the perfect opportunity. He may look composed, but he's secretly trying to catch his breath. His physical condition has deteriorated badly. The Mangekyo Sharingan alone is already a heavy burden on him."
