The Last City: Four Hundred Days to Survive

A sudden gray-fog catastrophe strikes Blue Star. Unknown spore viruses spread on the wind, with no incubation period and no discrimination in who they infect.

The dead rise as zombies. Any living person whose wounds touch the gray fog or zombie bodily fluids is infected instantly.

The virus continues to evolve: ordinary zombies → fast zombies → armored zombies → mutant nests → disaster-class aberrations.

Cities lose power, internet, and water. The law collapses, and order falls to zero.

The protagonist is in Linjiang City, Jiangbei, an ordinary young man from the bottom of society. With no System and no cheats, he relies on hard-core survival, using reason, courage, teamwork, and infrastructure-building to make it through four hundred days of apocalypse.
