What does the end of the ten deadly sins mental hospital imply?

First of all, you may not have noticed a sentence that the writer Liu inadvertently wrote on the wall: "What disappears above will meet again below." The above refers to this superficial mental hospital, and the following refers to the corpse processing factory. The hunchback said that Liu was discharged from the hospital unintentionally ten years ago. But will the dean and nurse of this mental hospital let him out? Of course not. In other words, Liu was killed unintentionally ten years ago and his organs were taken away. Then this organ was transplanted to Du Ping. Didn't you say that the transplanted organ carried the consciousness of the former owner? This kind of character, for Du Ping. In order to uncover this secret, the clever Liu unintentionally led the prisoner to take revenge step by step and led the task force to solve the case.

Ten deadly sins is a horror novel written by the writer Spider. This book is adapted from a real case. The place names involved are all pseudonyms. It introduced ten terrorist murders that happened around us, each of which was tightly blocked by the media and kept secret by the authorities. For example, snowmen on all fours, ghosts on rainy nights, cellar slaves, fur men, perverted perverts ... and the case of Diao dismembered bodies that caused a sensation on the Internet.
