Kabuto's god tree cell modifications had upset that balance-his chakra density had indeed reached tailed-beast levels, but the price was an extremely unstable system.
All it would take was an outside force pushing at the right frequency, and the entire system would collapse from within."
"So he didn't dare show up himself," Guy said. "Not because he didn't want to defend this experiment site, but because he knew the vessels' weaknesses all too well.
He knew that once the people Konoha sent found the resonant frequency, the vessels wouldn't hold."
"He knows how we severed the main root in the Bamboo Forest," Neji continued. "When Kabuto left Pheasant Feather Valley, he took fragments of the main root with him, along with records of its chakra fluctuations when it was severed.
He could work backward from those records and deduce that we used resonance.

Chisen switched off the analyzer, and the light from its screen faded from his face.
Dusk had completely enveloped the sea. The speedboat's bow light illuminated a small patch of water ahead, its light dancing constantly over the waves.
