Materials science graduate student Chen Guo transmigrated into a doomsday tool-character female supporting role, decisively ran away, and opened a waste maintenance station in the garbage district. Broken radios, old watches, broken radio stations, all come back to life in her hands. She only wants to fix things, not men, but who knew that fixing one radio would lead to receiving signals that shouldn't be received. Oases, military control committees, and caravans take turns visiting, while the secrets of A-07, K-00, and the North Bank Center emerge one after another, and a key pushes her into the limelight even more. The doomsday maintenance station is now in trouble.
