Yongye could feel the air vibrate, but it was nothing like ordinary hearing.
It bypassed his eardrums and formed a recognizable sound directly in his mind, as though imprinted on his thoughts—clear, directed, and never spilling into the air.

His gaze shifted toward the line of prisoners and settled on Asuma's profile. Looking at Asuma's deathly pale face, he let the corner of his mouth lift slightly.
