Shen Mo returned to Green Cloud Cave Heaven soon after, and marked a plot of land in the Demon Zone, releasing billions of creatures from Bliss Island.
To prevent mortals from being used by evil cultivators and strong aliens to practice evil magic, he thoughtfully divided the area into two sections... The larger area accommodated mortals, with an environment only slightly worse than the Mountain-River Zone; sustaining billions of people with agriculture or fishing and hunting would be no problem. The smaller area accommodated transcendent beings, and an array prohibition was set up to suppress their cultivation to prevent excessive slaughter and depletion of mining labor.
The task of selection was entrusted by Shen Mo to the Enforcement Hall and the Evil Punishing Hall, with disciples from both halls chosen to carry out this duty.
