In 2073, the "Scarlet" virus accidentally leaked out of Binhai City. Within ten minutes, the infected mutated into bloodthirsty and violent alien species, turning the once prosperous city into a living hell. Shen Yan, the chief mecha engineer of Xinghan Heavy Industry, glimpsed the tip of the iceberg of disaster from a seemingly ordinary laboratory accident warning at midnight when the apocalypse broke out.
When police sirens tore through the rainy night and the roars of zombies replaced the neon lights, Shen Yan relied on his logical thinking and emergency response capabilities far beyond those of ordinary people, armed with an emergency kit and a homemade electromagnetic pistol, and started a road to survival in a high-rise apartment on the 28th floor. On the way, he met doctor Lin Yue and detective Zhao Lei. The three of them broke out in embarrassment at the beginning, crossed the occupied streets, solved the crisis in the convention and exhibition center, and rushed towards the military base in the west of the city step by step - that was the only hope of survival in their eyes.
However, military bases are not pure lands. Not only is the scarlet virus core sample "Scarlet Matrix" raging here, but it also hides the shocking secrets of Xinghan Heavy Industries' genetic experiments. Shen Yan was forced to shoulder the heavy responsibility of weapon research and development, integrating mecha engineering technology into the transformation of doomsday weapons, from electromagnetic pistols to electromagnetic guns, from virus inhibitors to fortification upgrades. He used wisdom and courage to build a line of defense against alien species.
Mutated creatures continue to evolve: from cat-sized fast-attack aliens, to two-meter-tall, invulnerable mutant lords, to self-healing scarlet matrixes with terrifying energy. Every crisis is refreshing mankind's understanding of the doomsday. And the contradictions within human beings are equally sharp: conflicts caused by competition for resources, concealment of the truth about the virus
