Who knows?
After ten years of struggling in the apocalypse, she was reborn with a broken conveyor belt!
The key is that she still remembers the lottery number that won the 100 million grand prize before the disaster!
She has space to store supplies, looks good enough not to worry, and has the leisure to watch other people's exams. Other people's apocalypse is hell, while her apocalypse is a vacation where she "lays down and spends 100 million"?
This wave of rebirth makes a lot of money!
