Laplace's AI: Under All Seeing

You are being observed. Your anger, jealousy, greed, arrogance and other evil thoughts are clearly visible. After a hundred years of cataclysm, [Happy City-State] is the last isolated island of mankind. The omniscient Laplace AI system - it monitors your emotions of the seven deadly sins through everyone's eyes, and quantifies the root sins into colors in real time, all for the continuation of human civilization under order. Green is safe, yellow requires treatment, orange is contained, and red… Here, original sin is not just evil thoughts, but also some unspeakable thoughts. Lu Bai witnessed all this. And his own readings are always green - all because of a code deep in his consciousness, this programming that spans centuries. Until one day, he saw traces of that code on an old piece of paper before the disaster. It was something that could not appear in this era. When AI began to assign him to investigate cases that "shouldn't exist," he discovered that the city's deepest sins were hidden in the cleanest green.
