November 2019 Wattpad Sci-Fi Challenge: Write a story in exactly 100 words containing "One Earth"

This is the story of how I, Christopher, got the nickname Mercury, and it is less than pleasant.

Clouds darkened my hometown and everything silenced. Little did I know that scientists pumped something into my body from day one. That something was liquid mercury.

The scientists ran tests, trying solve what effect I had on Earth's climate - it was huge. At this very moment, my 'blood' was killing Earth, and that wasn't good - we only have one earth, after all.

Silence washed the town in blood-red air, then the dust came. It was too late. It all died.
