Tang Li Xue hastily looted the mine supervisors' storage treasures before she used her [Ethereal Form] and [Void Barrier] to conceal herself and quickly leave that place.
She just killed more than a dozen mine supervisors after all.
There was no guarantee that the Region Head Master Yu could not sense that more than a dozen mine supervisors, who had chased after Lucia and Yaya, had already been killed.
Just like Tang Li Xue had expected, Master Yu actually came to the location where more than a dozen mine supervisors had been killed and checked what had happened.
"These damn rats! It should be impossible for that stupid bird to kill all the mine supervisors by itself. It means there are actually more rats helping it! Just wait! I will make sure to uproot you all!" Master Yu said angrily.
Master Yu patrolled around a few more times to find Tang Li Xue, Lucia, and Yaya, but unfortunately for him, they were no longer there.
