Bring Disaster to People

The undertaker, Shen Du, groomed the deceased during the day and got off work on time at night, locking the door and sleeping. He can sense the remaining obsessions in the last breath of the deceased - this skill is called "listening to disaster". One night during the night shift, he discovered that part of a corpse had been taken away. Following the clues, we found that there were forty-seven accidental deaths in the past ten years, all of which were taken away by someone using the same method. What is the other party collecting? And why is he the only one who can find traces? The embalmer, who was afraid of trouble, was forced to be involved in a long mystery that spanned ten years.
