When the earth suddenly suffered an extreme cold wave of minus 60 degrees, the zombie virus mutated and evolved in the ice and snow, and Kyoto became a frozen purgatory. Subway engineer Li Mingyuan and his wife and daughter hid in the underground network, but unexpectedly discovered that behind this disaster were hidden the shocking secrets of the military's "Ice Princess Project" - ice crystal monsters, gene editing, underground rivers of radiation, and the fire of human civilization lingering on the three underground floors.
From the defense battle of Zijin Station to the competition for resources at Jubao Station, from the decisive battle between man and machine in the main control room to the exploration of the dark river abyss, Li Mingyuan's family struggled to survive in the apocalypse. His wife Zhou Hui's scalpel slits the zombie's throat, his daughter Li Xiaoran's stuffed rabbit hides a mutation code, and the subway map left by his father actually points to the "seventh container" that can save the survivors. When the homemade flag is raised at the vent, the boundary between human nature and bestiality gradually blurs in the absolute low temperature...
This is a wasteland epic about survival and redemption. In the frozen underground Great Wall, every choice questions the bottom line of civilization.
