Blue Star suffered erosion by the "gray mist", civilization collapsed, and survivors struggled to survive. Lu Yuan, a 28-year-old retired reconnaissance soldier, unexpectedly awakened the talent of "material analysis and recombination" in a desperate situation, being able to transform waste into survival supplies. He teams up with Lin Xia, a calm and resolute mechanic, and Lei Hu, a bold and forthright scavenger. The three of them must not only face the threats of a harsh environment, but also deal with the covetous desires of raiders. On the resource-scarce wasteland, Lu Yuan relies on his talent and wisdom to lead the team to build a sanctuary, uncover the truth behind the gray mist, and find a glimmer of hope for humanity.
