After the apocalyptic disaster, the rusted "Iron Dragon" train became a mobile hunting ground in the ruined continent. Lin Mo, who is cold, ruthless and logical, uses a decisive attitude to survive on the train. Faced with iron-eating rats, orbital crises, and the human game among survivors, the highly intelligent supporting characters all have their own agendas. In the hard-core road to survival without a heroine, only cold-bloodedness and resourcefulness can create a glimmer of hope in the apocalypse of the jungle.
