Twelve years after the nuclear explosion, the sky was gray.
Lin Wanqing was once a biological researcher in a shelter and is now the mother of a five-year-old boy. Her son Xiaoyuan suffers from stage three poliosis - a strange disease awakened by radiation that turns a person's skin inch by inch into a gray crust, eventually turning him into a living statue. The course of the disease is three to four months. In her hands, she only had half a bottle of water purification tablets, a rusty scalpel, and a metal plaque that her husband had given her on the day of the nuclear explosion.
There is a line of words engraved on the back of the metal plate: White Crow 17.3K.
In order to save her son, she walked out of the shelter and set foot on the surface. There are mutated dogs, bears, and insects in the wasteland, there are thinking primates, there are markets where water purification tablets and bullets are traded, there is an armed settlement that calls itself the "Iron Throne", and there is also a legend that there is an oasis without radiation in the south.
She met the one-armed Lao Chen. He exchanged his robot hand for food and guarded an abandoned gas station with a dog named Huihui. His daughter died in the year of the nuclear explosion. He has never accomplished a big thing in his life.
She met the taciturn White Crow. She once studied ash disease and now practices medicine in the wasteland, carrying a metal box on her back that cannot be opened. Her daughter is called Niannian, and she loved sunflowers the most during her lifetime.
She met Zhao Tiezhu. He rules the Iron Throne and believes in a saying - "Hope is the biggest lie." He once heard "Oasis" on the radio in a shelter, and then all the people in that shelter died.
Everyone has their own ruins. Everyone is looking for someone who can't go back.
