In the Pure Land, the Sage of Six Paths stared intently at the conversation on the Sky Screen, his brows tightly knitted and his expression utterly grave.
Watching Black Zetsu casually deceive Indra, speaking so lightly of Yin-Yang Release and Truth-Seeking Orbs, he could not help shaking his head, filled with helplessness.
Others had no idea how terrifying the requirements for those two powers were. Even the extraordinarily gifted Indra on the Sky Screen had been kept completely in the dark.
He sighed inwardly, silently reviewing the true principles governing the world's powers.
Quite a few people could indeed gain a rudimentary grasp of Yin-Yang Release and barely wield a fraction of it, but that hardly counted as mastery.
Truth-Seeking Orbs, however, were absolutely not something one could obtain through arduous training, obsession, or effort!
Across the entire Shinobi World, from ancient times to the present, there had only ever been one orthodox path to creating Truth-Seeking Orbs oneself.
Only by fully mastering Yin-Yang Release while simultaneously controlling all seven chakra natures-fire, wind, lightning, earth, water, yin, and yang-could one create Truth-Seeking Orbs.
Those requirements were harsh in the extreme.
Even among the countless prodigiously gifted shinobi who came later, even among the successive reincarnations of Indra and Asura, not one had ever accomplished it.
The reason he and his younger brother, Hamura Otsutsuki, had mastered them so easily and could create them at will was not training at all. They had been born with that ability!
Only by inheriting the fundamental bloodline and chakra of their mother, Kaguya Otsutsuki, had they possessed the necessary qualifications.
Apart from the two brothers, no one in the world could obtain that power through orthodox training.
Beyond that, only two shortcuts existed in the entire world for accessing the power of Truth-Seeking Orbs.
