In the thirty-seventh year of modern times, the sky was shrouded in rusty metal clouds, and the technological remains of the old era piled up on the earth to form absurd city-states. The rain is stained with blue-green rust, and when it falls on the skin, fleeting old-world advertising slogans emerge. People survive by dismantling "memory chips" in the ruins. The chips contain fragments of other people's lives. Some people use them to piece together the past, while others use them to escape reality.
When Lu Jinye woke up, there was only half a bronze gear engraved with unfamiliar patterns in his pocket. He had no memory, but he could understand the "whispers" of the mechanical remains in the ruins. He traveled through the deformed market where "lies" were the currency, and met a one-eyed merchant who sold dreams, a tower keeper who raised electronic butterflies, and a crazy old man who called himself the "Time Tinker."
As the lines of the gears gradually became clearer, he discovered that every time he touched the core machinery in the ruins, a distorted "image of yesterday" would be triggered. And the fragments of these images point to a secret that has been deliberately erased - above the rusty sky, there seems to be a huge lie that can subvert the entire apocalypse. His path of pursuit continues to stretch between absurdity and reality, stepping on the bones of the old era and the delusion of the new era at every step.
