Three hours before the zombie virus broke out globally, former special warehousing expert Chen Feng exposed the coordinates of twelve secret reserve granaries, and instantly became the 'Doomsday Grain King' that the entire Internet begged for refuge. Female doctor Zhao Shuang defected with a mutated virus sample, but attracted the covetousness of the careerist He Ting. Chen Feng led the survivors to establish a base in the granary, resisting the tide of corpses while fighting openly and covertly with He Ting's warlord forces. From the young hacker Shen Mo to the veteran Fang Dashan, every defector has a secret that no one knows. When Chen Feng discovered that there was a conspiracy behind the virus leak involving an international biological company, and that the granary he disclosed was actually a trap carefully set by others, the real end had just begun.
