My name is Chen Mo, a former criminal police officer, and now I have an unpopular job - helping people deal with haunted houses.
There are always people grabbing cheap second-hand houses, but not everyone can touch a haunted house. In each haunted house, there is a rule sheet left by the previous deceased. The rules are true and false. If you violate them, you will die. If you do not survive for seven days, you will become part of the house.
My grandpa is a Feng Shui master. I know how to see ghosts with my celestial eye, and how to transcend and send souls. I have a brain trained as a detective to break through these rules and traps.
What you earn is money for working hard. If you solve a haunted house, you will get a 10% commission. As long as you can survive for seven days, you will get the money and leave.
After all, there are always people who want to buy cheap houses, and there are always people who have to help them clean up the mess in their houses.
