Project Rebirth: the Incompetent

One day in the future, every 15 years, the whole world will jointly select 1/5 of the world's population for talent screening. Those who fail the screening are called "incompetent people". They will be stimulated with unprecedented potential and kill each other until they are finally trained into war machines, and they will also become the victims and trump cards of the war. We will use Neo's vision to experience and understand this cruel screening plan. What is Neo's experience and what will happen in the end?
