That night when scarlet spores rained down like blood, humans finally understood that they were not the masters of the universe. Alien alien "Star Eaters" tear through the ionosphere, their biological warships can swallow nuclear bomb energy, and their stretchable silicon-based tentacles can instantly crush main battle tanks. What's even more terrifying is its method of reproduction - transforming living humans into wriggling hatchlings. The city's sewers are filled with half-human, half-monster aberrations.
When Lin Feng, a former member of the special forces, rescued surgeon Su Qing on the run, the human regular army had been defeated for 97 hours. They hid in the subway tunnel, behind them were alien hounds that could sense life through vibrations, and only had shotguns and scalpels in their hands. When Su Qing cut open the alien larvae and discovered that its nerve bundles were sensitive to infrasound waves, this remnant team, composed of teachers, auto mechanics, and retired police officers, began to use fire axes to split ventilation pipes and use gas cans to make improvised bombs. In the maze of steel and concrete, they dug the last way out for human civilization.
