After discussing all the options they had, the exorcists unanimously agreed to try to gather information from other sources first, and avoid approaching Pi Enshu unless absolutely necessary. She probably wouldn't be willing to cooperate, anyway. Someone who murdered so many people, and with such brutality, was unlikely to show any remorse.
They didn't know what exactly bound the woman to this world, but knowing she was the killer, it couldn't possibly be anything good. Perhaps even after death, she was unable to let go of her murderous tendencies… In such a case, appeasing her would be out of the question. Once they found out everything they needed to solve the case, they would exterminate her ghost. Her soul would then be destroyed, and she would never be able to reincarnate, but she deserved such an end. Even Yu Qingyu agreed on that.
