Lu Yi, an insurance claims investigator, was drawn into the never-day Ember City on the commuter subway and was forced to participate in a death game led by the Twenty-Two Mysteries. When the survivors began to awaken to supernatural powers, thinking that they could become gods as long as they cleared the level, Lu Yi discovered through loopholes in the game rules: This was not a god-making trial at all, but a soul harvest to delay the collapse of the high-dimensional world. The only way to break the game was to completely destroy the Truman world.
