Lanzhou was shrouded in gray-white plague fog overnight. The LS-7 gray plague swept across the city, and aberrant monsters wandered in the ruins.
Everyone thought that the natural disaster monster was the culprit of the apocalypse, but no one knew that the source of this disaster that destroyed tens of millions of people was just a silent and thin little girl.
She is a living virus experimental subject secretly cultivated by the government, a walking source container. The fall of the entire city was never a natural disaster, but a planned sacrifice experiment.
Wen Xiao and his team of survivors were trapped in the ruins on a rainy night. Their retreat was blocked by an official hunting team in black uniforms. The road ahead was filled with a steady stream of corpses.
The other party pretended to cease war and cooperate, but in fact they only wanted to capture the girl alive, control the power of the virus, and restart the taboo experiment.
Protect her, and the whole team will be buried in the gray mist; hand her over, and the entire human world will become an experimental purgatory.
There are bloodthirsty monsters on one side, and greedy people on the other. Everyone is plotting every step, and there is only a thin line between good and evil.
When the whole world wanted to sacrifice this innocent child, only this group of ruin walkers, against all conspiracies and malice, revealed the truth of the doomsday buried in the fog.
