Gray rain pours down, the virus destroys the city, the doomsday comes, and the world becomes a hunting ground.
A strange acid rain overturned the world, living people were alienated, zombies were rampant, and all the former prosperity turned into a ruined wasteland.
Lin Wan, a former nurse, is obsessed with finding a girl. She wanders alone in the dead ruins. She encounters the cold engineer Shen Yan and takes in the orphaned girl Aya. The three of them team up to survive in a desperate situation.
They thought the refuge base was the last pure land, but little did they know that there were surging undercurrents and a shocking conspiracy hidden underground.
Man-made biochemical experiments, brutal plundering of villains, and more powerful mutated monsters followed.
When the world sinks into darkness, there is a fierce battle between good and evil in human nature.
To survive in a desperate situation, use flesh and blood as a shield to guard the glimmer of light in your heart.
The gray rain will never end. Only by moving forward together can we find a glimmer of hope in the desperate situation of the end of the world!
Purpose: After the collapse of civilization, human nature's choices of good and evil struggle against the dignity of ordinary people
