Scavenger Chen Yan finds a diary in the radiation-ravaged ruins and uncovers the secret that the "sky screen" protecting the people is a century-old hoax. The source essence sustaining it is nearly depleted, and the elders are doing everything they can to bury the truth.
When the settlement's water turns foul and children fall ill, the only path to survival lies in the forbidden "key." Should they cling to a false sense of security and wait for destruction, or cut through the lies and walk toward a real dawn filled with unknowns? Chen Yan grips the burning-hot diary and heads for the heart of power. Behind him, wildfire spreads across the land; before him, rust-colored fog lies thick.
