A global Extreme Heat Apocalypse (70°C) breaks out. Luke Lu, betrayed and killed by his girlfriend and brother, is reborn seven days before, awakening a Frost Replication Space (-18°C, infinite supplies).

They establish the Serene Cove safe zone, take in survivors, defeat criminal forces, contain Cholera, and lead reconstruction on the wasteland.
