"This black stone will stabilize his soul body and prevent it from being harmed."
Nian Shutong did not mention that the current Yu Zeming did not meet the strength required by a ghost cultivator's soul at all. This large black stone was the last place where Fu Yunhe's soul had an out-of-body experience, at the bottom of that deep pit, the same place where Fu Yunhe obtained the ghost cultivator's legacy.
Nian Shutong had already communicated with Fu Yunhe. These stones can nourish spiritual bodies, making soul bodies more solid.
What she needed now was to make Yu Zeming's soul body grow stronger. Only then could she take him away and put Yu Zeming on the path to becoming a ghost cultivator.
As for the cultivation technique for ghost cultivation, Nian Shutong had it. In her past life, several oblivious ghost cultivators had provoked her in the Cultivation World, and after killing them, their storage rings or any storage space became spoils of war.
