The moment the shackles closed, Lin Mu sensed faint formation fluctuations spreading through the metal. 'Formation shackles.'
The masked cultivator stepped back and the apparent leader calmly raised one hand. His index and middle fingers extended together as a simple hand seal formed.
Then he spoke a single word. "Restrain."
The shackles instantly activated and Lin Mu felt tremendous force seize control of his limbs. His wrists snapped together while his ankles followed. His entire body straightened and his back became perfectly upright.
His shoulders aligned on their own and even his head adjusted itself. Within a heartbeat, Little Bull stood ramrod straight. Every attempt at movement immediately failed as the restraints ignored physical strength entirely. They directly controlled posture itself.
Lin Mu quietly experimented, only the slightest amount and the restraints indeed proved impressive. Breaking them remained possible.
