Xiao Niannian, a female special forces soldier in the apocalypse, accidentally traveled to Xiaojia Village in the Longxia Kingdom in the 1970s. She relied on her skills and mysterious system to resolve the crisis of forced marriage, protect her grandmother, and regain the property embezzled by her relatives and the state-owned Red Star Mine to collect clues. On the way south, she encountered a dangerous situation on the train and was forced to protect the elderly and rescue abducted children. She formed a tacit understanding with Lu Jing, the rescue captain of the Red Star Mine, and thus entered the life of the mining area. After entering the women's rescue class of the Red Star Mine, Xiao Niannian continued to prove herself in ordinary basic training and mine rescue duties. In the forced response time and time again, Xiao Niannian kept her name, family ties, position and the right to choose life.
