Lighthearted, slow-paced, apocalypse
A week before the extreme heat arrives, the ordinary protagonist receives one piece of good news and one piece of bad news.
The good news: they have a System.
The bad news: the System can't provide much in the way of practical help.
The ordinary protagonist says:
Huh? Wait, you haven't got the wrong Host, have you? I'm just an ordinary person. What makes you think I can save the world?
Later, the System watches this Host, who calls themself “ordinary,” lift a hundred-ton car and punch a meteorite.
Host, are you telling me an ordinary person can shatter a seven-kilometer-wide meteorite with one punch and come away unscathed?
