The Jade Cicada Is Silent

I knelt in the ancestral hall and tied a red rope on Ah Su. The veins on the back of his hands popped out, and there was blood between his fingernails, which was left when an iron hook pierced his shoulder last night. But he was still alive, standing in front of me, his breath warm. This is not right. Ah Su died a long time ago. On the night my son fell into the water, he sank into the lotus pond and no bones were left. And now, I personally take him out of hell and absolve him of his sins. I want to touch his face, like I did when I was little. But I remember... I am his master, and he is my secret guard, but Po Meng said that Asu's soul has returned to Wangchuan and has been unable to reincarnate. Why? Why?
