When Black Zetsu said Uesugi Shinji had mastered Senjutsu, Uchiha Madara furrowed his brow slightly and asked skeptically, "Are you sure? As far as I know, he shouldn't have had a chance to visit the Three Great Sage Regions."
A strange look flashed in Black Zetsu's eyes as well. "His Senjutsu bears no trace of the Three Great Sage Regions. If I couldn't tell that he'd successfully fused with Natural Energy, I wouldn't have believed that a human could use Senjutsu without going through the Three Great Sage Regions!"
