The Western Demon King, frightened by the pack of wolves, jumped up and realized that the previous bindings and controls were gone, allowing him to move flexibly, and so he began to run away at speed.
"Howl"
Suddenly, a transformed Wolf Demon appeared in the space, a form definitely not of their kind. At first, the pack only surrounded and observed it without attacking, driven simply by curiosity.
Then, the guilty escape of the Western Wolf Demon caused the pack to howl but not to attack, having received no orders from the Wolf King to do so against this foreign species.
The Hell Palace Artifact Spirit enlightened them that this was a Wolf King from the West and that he had followers, albeit some were annihilated by their master.
The reason for bringing it into this space was its loose tongue; it had insulted its master as foolish and claimed that Western wolves were mightier than Eastern wolves.
