The red mist swept across the world, giving birth to mutated creatures and fog-keeper organizations, and humans fell into a desperate situation of escape. The protagonist Lu Chen awakens the ability to control fog, which can be deeply integrated with metal. With vehicle modification as the core, he forms a team, starting from a pickup truck, and gradually builds the ultimate mobile bunker "Rock Fortress", leading the survivors to resist the fog keepers, destroy the source of the red fog, and rebuild their homes.
