Mechanical Shrine

In the apocalyptic wasteland, the rules are the laws of physics. People who break the rules will be silently deleted - those who crawl over will survive, and those who walk past will disappear. There is only one person in the entire wasteland who can see the "notes" under each rule. Others rely on fate to test the rules, but he relies on the rules to make money. His name is Lu Chen. After ten years of scavenging, he saved thirteen screws. Until he discovered that the "oil" behind the rules was almost exhausted.
