In Spirit Star, because cultivation requires many heavenly and earthly treasures, many cultivators have no intention to seek another cultivator for Dual Cultivation.
Engaging in Dual Cultivation with another means sharing one's cultivation resources with someone else to a certain extent.
However, these cultivators still wish to have a child to accompany them.
Thus, they directly go to the Yanling Sect, using such a method to give birth to their own offspring.
Some families also choose to do this due to a lack of heirs.
Only, the Long Family had never done so.
They believe that although the child may indeed have the bloodline of the Long Family, since they were not conceived through normal means, there was always a thorn in their heart.
On the other hand, the essence blood of a cultivator, especially from a major clan, should never be disclosed.
Once the essence blood is leaked, those who obtain it can use it to find many ways to target the original owners.
