The Northern Myanmar Hellhole: Men and Women Alike Are Abused

I Read a Novel Where the Male Lead Tricked Ghosts and Harvested Their Kidneys, But He Didn't Start Out Doing That

I'm looking for a novel about making a fortune by harvesting kidneys. There's a scene where the protagonist invites several villains over. The villains on the other side all think one of them got into a fight with the protagonist, and they seem to have both been badly hurt. Then the male lead comes over and harvests their kidneys. Does anyone know what book this is?
