In this world, time no longer passes, but comes like the weather.
It will rain, it will snow, it will fog, it will frost. If you get caught in a time rain, you may age for decades in a few seconds; if you encounter a reverse time frost, you will be dragged back to the most painful day in your life, repeating the cycle until you go crazy.
Jiang Ling is an observer in a low-lying area. She has a secret: she can smell time disasters. The smell of ozone before the time rain comes, the smell of rust during the time snow, and the smell of sweet rot when the reverse time frost comes.
Twelve years ago, a time disaster took away her sister. Everyone said that my sister was dead. Jiang Ling didn't believe it.
Until that day, she picked up a line of words in the reverse time frost:
"Stop checking, you will kill everyone. - From you 27 days later."
The sender is herself. From your future self.
And the future version of her wants to kill a child.
The child, now hiding behind her, calls her sister.
