A "graphene virus" caused all petroleum-based plastics around the world to degrade within 72 hours - infusion tubes disappeared, hard drive racks were shattered, and supply chains were broken. There are no zombies, no superpowers, just human civilization that suddenly fell into the pre-industrial era.
Nurses remade IV tubes from bamboo, programmers carved codes into wooden boards, and farmers discovered an ancient plant fiber that could replace plastic... But these scattered glimmers were quickly snuffed out by a company that monopolized the formula of "bio-based plastics." They used patents to build city-states, asked the people to exchange food for materials, and used technology to recast shackles.
An "Open Source Commune" composed of farmers, nurses, librarians and retired soldiers decided not to be Avengers, but to be enlighteners. They used radio broadcasts of breeding methods, used open letters to break down patent barriers, and used ten years of perseverance to prove that the world was not destroyed by garbage, but by people who forgot to think.
This is not about survival in the wasteland, but a chronicle of ordinary people rebuilding civilization. When the clay is turned again and new conventions are born on the scorched earth - you will find that the real end is never the collapse of matter, but the exhaustion of imagination.
