There are still seven hundred days before the natural disaster strikes, and the world has fallen into chaos. Mechanic Chen Feng was sent to the deserted Patrol Area No. 14 With the task of repairing the abandoned signal tower. However, he discovers a secret under the tower - a giant nest of genetically mutated worms, which contains a living supplier that converts wanderers into biofuel. Chen Feng must use his recycling skills to piece together weapons from scrap metal and corpses, destroy the worm nest before the countdown ends, and reveal the conspiracy behind the signal tower. This is not a story about saving the world, but an ordinary person's struggle to survive in the apocalypse.
