Lu Yin took hold of the slipper and climbed onto Prison Dragon's back. Suddenly, Prison Dragon shivered, as if something bad was about to happen. It slowly turned its head, one claw still in its nostril, and looked at Lu Yin on its back. Then its eyes fixed on the slipper in Lu Yin's hand, its pupils shrinking.
