On the eve of the re-examination of the world, murder cases occurred one after another in Qingping County, where doors and windows were locked but the doorman gave no warning. Shen Yan, an official at the ancestral hall, found out that the deceased in the official household registration had already moved away, and the house he lived in had been owned by Yizhuang. As the investigation deepened, he discovered that the real murderer was using three lives to create a common ancestor for 137 refugees who did not exist in the official register.
