The tyrant Gu Qing disregarded human life and did so many bad things during his lifetime that he could not even go to hell after his death. He could only go to the Palace of Hell to work as a laborer - the God of Death.
***
In the Palace of Hell:
Gu Qing: "Damn! Why should I act like a bull and a horse for you?"
Yan Jun: "Meeting performance standards will allow you to see your wife again."
Gu Qing: "Deal."
Intention: Never give up in life after life
