September 6, 2069, Apocalypse Day, D-100
100 days after Apocalypse Day, the Joint Train led by Dragon Mountain No.1 and Infinity proceeded east from Akse into the vast uninhabited areas.
At 10:02 AM, the sun burned like a white-hot forge rod, piercing straight into the bare spine of the Gobi Desert. The Joint Train raced over the rust-brown gravel plains, and the saline-alkaline soil on both sides of the tracks evaporated into mirages, twisting distant wind-eroded rock pillars into flickering candle tears.
