The female ghost was driven by Shen Dongdong, who led Su Xiaotong to the sacrificial altar at the mountain peak and handed her over to him.
When Qin Zhao returned, he saw Su Xiaotong had fainted from the erosion of ghost energy, and Shen Dongdong was dragging her to the key location of the array.
Alerted by the noise, Shen Dongdong's eyes immediately turned wary and he fiercely clutched Su Xiaotong's throat.
"I've already agreed to your terms and let those two people go. Why have you come back?"
"I had no choice," Qin Zhao said, "she is my agent."
"No, I can't let her go again! My array must be activated successfully!"
"How about this: You tell me your wife's date and time of birth, and I'll help you summon her soul."
The soul summoning that Qin Zhao knew was much more advanced than this array. It didn't require a human sacrifice to summon a soul that hadn't yet reincarnated.
