[Marvel·Dog Chain lv.11: 0/4 (The target that is chained will become humble and obedient like a dog, ineffective against intelligent creatures, ineffective against targets above level eleven; cannot be upgraded)]

Thinking about these things, Yang Yuan released the Dog Chain and jumped down from the back of the Funeral Crow.
