Genetic Doomsday Timing

The countdown to the end of the world started on the day my brother died. He sent a final warning: "The drug that makes the world perfect... Is poison." What was then unlocked was a map of genetic bombs all over the world. The red dot flashes, and there are 71 hours and 59 minutes left in the super city where I am. My name is Wang Qiang. In my previous life, I watched civilization collapse after seventy-two hours. In this life, I return with memories. Those giants who use genetic medicine to create "perfect humans" think they are promoting the era. I'll tell them with bullets: Who is the era itself. ——Hard-core science fiction survival "Genetic Doomsday Timing", an entry for the Galaxy Essay Competition.
