Frozen Apocalypse: I Am Reborn to Lay Out Global Railway Tracks

Three months before I was reborn in the apocalypse, I sold all my belongings and went crazy to lay railroad tracks around the world. Others laugh at me for being crazy, but I laugh at them because they don't understand. The glacial apocalypse is coming, and my steam train is the only way to survive. There was a riot at the bottom, and the rebel leader put a gun to my head: "Give me control!" I pointed to the weird snowflakes outside the window: "Do you know what the temperature was when the snow stopped last time? Seventy below zero!" "Guess how much it is this time?"
