It should have been a problem with the seal. Though I said I could hold out for five minutes while fighting Obito.
That was just a bluff, meant to make Obito abandon the idea of stalling for time.
In reality, my temporary reinforcement wouldn't last five minutes.
Now that I thought about it, Kushina's Jinchuriki seal had probably reached another dangerous point.
Minato Namikaze likely hadn't rushed over because he was repairing the seal.
As Chiba darted through the mountain forest, his brows slightly furrowed, this string of thoughts passed through his mind, easing his worries somewhat.

Although Kushina's Nine-Tails Jinchuriki sealing system used the Four Symbols Seal system, it was among the most difficult and complex of its kind. Every Jinchuriki sealing system was essentially the most complex and difficult within its own sealing system. It could even be called the pinnacle of every corresponding sealing system.
Even with Chiba's current level of Sealing Jutsu, it had been impossible to restore the entire Nine-Tails Jinchuriki sealing system in the mere dozen or so seconds he had had.
