"Since you want to confess, then detail how you became an Immortal, how you took lives, and how you manipulated people!"
Seeing that Xu Qing was intent on killing, the female ghost's spirit wavered and had to confess the truth.
As for the specifics, it all started last year, during the twelfth lunar month.
At that time, Chen Mancang used the Nightmare Technique to bewitch someone at Qushui Stockade and was seen by the woman in the red dress.
To be fair, this female ghost was not a genuine Immortal; she merely took over the incense offerings at Qushui Stockade's vacant shrine, which had no real deities.
However, to become an Immortal, having a shrine isn't enough. You need to gain the support of other Immortals as guarantors.
To legitimize her status, the red-dressed female ghost allied herself with other dismal Immortal halls in neighboring villages.
