Lin Yu, a project manager, travels to the wasteland a century after the catastrophe and becomes an 18-year-old orphan, bound to a damaged Civilization Reconstruction System. With no superpower shop, she relies on knowledge, infrastructure development, and management skills to survive. She builds a water purification device with her own hands, hunts mutated creatures, saves the scavenger Old Jack and the mechanically gifted girl Alice, and later rescues Ghost, a modified death soldier from the Black Prison, forming a team. Together, they escape the dangerous Rustwater Town, cross snowy plains, survive Deathclaw attacks, and risk stealing a nuclear battery to repair the reactor of the abandoned Shelter 73. In the brutal wasteland, they fight mutated giant beasts, raider factions, and pursuers from the Black Prison while building a base from scratch and struggling to rekindle the spark of civilization.
