Reborn: My Scorching Revenge

After her Rebirth, Elara Cole learns the apocalypse changes from Arctic to 70°C high temperatures. She builds a heat-resistant safe house, stockpiling supplies. Her colleagues, who betrayed and cannibalized her, hoard cold supplies. Desperate, they retaliate, and villagers besiege her for supplies. Elara Cole uses The System's props and wits to resolve crises. She joins scientists, stops the apocalypse (at cost of rebirth), avenges past life, and gains freedom.
