The baby who died at the beginning actually was elevated to a xian, while her twin sister Xie, the girl found in the temple, does not, and seeks to follow her sister's step. Both of them have double pupils in one eye, a sign of emperor and God since ancient time. Turns out the twin tried to became Xian in previous life but failed. In this life, xie, with the help of her sister haunting the detective's daughter, rendering her not able to speak, has to kill five morally reprehensible people to represent the hell of ice, fire, heart-removing, intestine-removing and tongue-removing. The two men were their apprentices in last life and are there to help Xie in this one. The finishing step is for the detective to kill her. And for that, he is allowed to elevate with her. But in the end, his daughter who can finally speak makes him shed tears. Maybe he comes back to life. Maybe not. But the text running at the very end shows that with love there is no regret, or with love, one is there to stay(in two different versions of the ending).
