堅尼地道殺人事件

The master trainer's business has developed into a conglomerate and is being developed in a community center in an impoverished area. The community center is ostensibly a non-profit volunteer organization, but in reality, it uses the elderly and infirm to help the organization to engage in criminal activities and make huge profits. A group of young volunteers from the center gather secretly in the basement every night, and the master trainer brainwashes them with the idea of hating the rich and making the world a better place by assassinating the rich and committing drug crimes for the organization, so that they can regain the goal of their lives and help the organization loyally.
