Head Hunter.

Shi Lang did not leave the Asura hall right away. He told Yang Niao to have a few disciples go down to the valley and converse with the ghost cultivators to see if they could reach a collaboration. This will be progressive for them. He also made an array plate that would trigger the mental demons faced by all the cultivators in the group. 

This allowed them to temper their minds and achieve a better spiritual ground. If the disciples were to reach a level where they could not continue, the array would stop and send them out. At the same time, he assigned a task to the array of master disciples in the Asura hall to develop an artifact that could be used to communicate even from a great distance.
