When quantum light shines in the radiation fog in the Rust Belt, garbage dump scavenger Lin Ye is forced to become the "key" to the apocalypse. An awakened mecha engraved with Fibonacci cracks, and a string of transplanted memories encrypted by the military, drew him into the strangulating vortex of the Mechanical Cult, the plutocratic group, and the alien sowers. In the electronic sound of AI "Zero" becoming more humane, in the crystalline growth of the body's alienation into a quantum state, he discovered that he was actually the living key to the "Ark Project" twenty years ago. When the seven-day twilight protocol starts counting down, the pulse signal of the underwater city resonates with the computer array on the dark side of the moon. The truth of the end of the world is actually the button for advanced civilization to restart the universe - will it become the last observer of mankind, or will it become the light of entropy reduction in the mechanical dawn? Cyber fighting is intertwined with quantum philosophy. Every time the memory lattice is shattered, it is closer to a cruel awakening.
