It was Adamantine Sealing Chains!
This was one of the Uzumaki Clan's most powerful Sealing Jutsu, said to possess the terrifying power to suppress even a Tailed Beast. Of course, Naruto was using only a small fraction of that power now, deliberately keeping the chakra within the chains at a level equal to Satsuki's.
Faced with the golden chains shooting toward her, Satsuki used the Body Flicker Technique without hesitation. Her figure flashed, narrowly escaping their coils. Knowing she could not afford to touch them, she immediately formed hand seals as she retreated.
"Fire Release: Phoenix Sage Fire!"
Several blazing fireballs hurtled toward the pursuing Adamantine Sealing Chains like scattered crimson lotuses! Yet the golden chains burst through the smoke of the exploding flames completely unscathed, racing toward Satsuki's new position without slowing!
This is trouble! Satsuki kept changing positions with the Body Flicker Technique to evade them, her eyes fixed on the thick mist ahead.
My vision's completely blocked. I can't see Naruto himself at all. And those chains are so fast that I have to keep using the Body Flicker Technique just to barely dodge them. It's burning through too much chakra. I won't last long at this rate!
And how is Naruto pinpointing my position through all this fog?
There was no time to puzzle it out. Satsuki knew that continuing to defend passively would only lead to defeat. She had to take a risk to break the stalemate!
Her thoughts raced, and a plan took shape. After her next Body Flicker Technique carried her clear of the chains, Satsuki anticipated that they would immediately turn toward her new position.
This time, however, she did not dodge again. Instead, she quickly pulled a small scroll from her ninja tool pouch—a secret scroll containing a specific Ninjutsu.
