Lightless Era: Day Zero

The boy tells his father's nanorobot to "absorb electrons" and "copy yourself," and the world's electricity completely disappears within five seconds. Cities were paralyzed, civilization regressed, and modern people returned to the farming era overnight. The father took his family and witnessed in the darkness that the neighbors turned against each other, order collapsed, and trust became a luxury. This is not a disaster caused by a virus or war, but a chain reaction caused by an accident. When the coat of technology is peeled off, humans are forced to relearn how to make fire, how to walk, and how to love each other.
