Smuggling Dna — Sunny Day

Lilly read the largest pre-Columbian empire on Earth was destroyed by the Spaniards' smallpox, horses, and guns. As the Spaniards took over the Incas' mines they increased the silver and its dust making them the first massive toxic-air polluters on Earth.
Lilly decided to write a science fiction story about evil scientists destroying people not with viruses or guns but with contaminated DNA. She'd rescue humans with help from her family, friends and Futurism, a non-carbon-based being. Futurism would use mysterious floating-molten dust to repair Lilly's DNA while he taught her how to properly respond to someone who was flirting with her.
Naturally, Lilly would practice his lessons while she told Futurism her story about stopping time, traveling to Earth's last ice age, and Smuggling DNA.
