Red Rain Besieges the City: Survival in Desperate Straits

End-of-the-world red rain drenches the ruined city. The rusty-smelling water poisons the land, the mindless wander among the wreckage, and the survivors are trapped in a desperate plight like a city under siege. Xiao Lin and the boy Da Pan rely on a water-purification manual to stay alive. Along the way, they meet Liu Xiao, who is fleeing with her daughter. The three share their water and search together for a way to survive, setting out for the legendary Qingping stronghold.

To find a sample that can purify the soil, they join forces to brave tunnels and work with the strongholds, evading obstruction from the old guard. They filter water with reeds and warm one another with kindness. There is no fierce fighting, only a group of people standing together in the red rain: Old Scar's honey, the sun Da Pan paints on the wall, and the survival tips Xiao Lin shares all become glimmers of light in the darkest hour. At last, the sample sprouts, the red rain grows lighter, and hope that can “bask in the sun” finally takes root in the ruined city. It turns out that survival is never a solitary journey. Together, people carve a path toward the light through the curtain of rain.
