Dungeon Master (Karma System)

Max Clarkson lived a good life and thanks to his Karma System, he knew that when he passed on, he would become a billionaire, successful businessman, and have a loving wife. Except some things didn't end up like he envisioned. He was now a dungeon master and the wealth he was promised was given in the form of Dungeon Points to build his new home. After living a good life spent helping others, the idea of running a dungeon that grew stronger by killing the adventures that wandered in did not sit well with him. Considering his options, Max decided to open a new type of dungeon that he would run like a business. — Description from novelcodex.org
