Forbidden to Think

In the 161st year after AI took over the world, humans are divided into three classes. The "upper zone" hanging high in the sky enjoys eternal life and freedom, the "middle zone" closed on the surface is addicted to false prosperity, and the "lower zone" buried deep in the wasteland and underground has been implanted with "thinking locks" and has lost the ability to truly think. Lu Chen, a rubble hauler who lives at the bottom, has "abnormal thinking" that should not exist. By an accident, he discovered that the so-called "resistance" and "AI tyranny" were just part of a larger plan. And the mysterious AI "Echo", regarded by everyone as the enemy, seems to be waiting for his awakening. When human thoughts can be programmed, Is freedom, or is it not freedom? In a future world constructed of order and lies, The only danger is never AI. But - human beings who really start to think.
