Yechen shifted his gaze to the people gathered around the Seven-Tails.
Indeed, several Takigakure ninja were beside the Seven-Tails deep within the cavern. They lay prone on the ground, concentrating intently on drawing the Sealing Jutsu Formula.
The Sealing Jutsu Formula appeared to consist of two sections, like two semicircles joined together.
