One of them of them was named Bing Ling while the other was named Yue Ling. Both of them were Gold Core experts. They had privileged positions in Extreme Yin Gate as they were disciples of Old Devil Purple Yin Kidd (Purple Yin). They were also his concubines and cauldrons.
Furthermore, the rest of the Harmonious Spirit female cultivators were also Purple Yin's concubines.
All of the seventeen girls had one similarity – they were all virgins. Since they were all virgin, their Yin energy was still pure. This was quite a special case as females who practiced Evil Dao would not remain chaste.
These girls were Purple Yin's women that were nurtured by him as cauldrons. The only reason that he nurtured them as such was to absorb, through plucking, their Yin energy to supplement his Yang energy when he reached the Nascent Soul ream.
