The Sternest Godfather of 100 Billion Demons

"Brother, let me tell you a trivia fact. There are about 100 billion human beings on the earth who have lived and passed away. That is to say, if every dead person becomes a ghost, each of the 8 billion people alive now can be assigned 12 ghosts." "No, what do I need a ghost for? Don't give it to me!" "That's the problem. No one wants ghosts. Let me manage them all. Can I manage 100 billion evil ghosts?" "No, it means you can control ghosts? Can they listen to you?" "That's a good question. My usual approach is to give them an offer they can't refuse." Ps: This book has a supernatural setting, but it is not the main focus. Readers can read it with confidence.
