In 2077, when nuclear winter has enveloped the earth, the surface has become a distortion zone, and humans are huddled in underground cities.
Lin Shen, an orphan with "empathic touch", was forced to become a doomsday courier because of a mysterious mechanical pocket watch. Each package is connected to the obsession of the dying person, and the bloody past can be seen at the touch - the mechanical dog that sheds tears hides the dying data of the scientist, the mutated flower core that sings is embedded in the girl's cochlea, and even the radioactive soil screams the grievances of the rebels.
His team each has its own secrets: the AI navigator Su Li is a fragment of the scientist's consciousness, the old knife with a broken leg hides the suspicion of matricide, and the petrified girl Xiao Qi's blood can cure radiation.
When the pocket watch unlocked the genetic code left behind by his mother, Lin Shen was shocked to realize that what he had sent was not hope, but the truth that could subvert the world - the aberration zone was a genetic pasture, and the Hope Center was raising new humans, and he was the perfect experimental subject.
"Mission failed, nerves burned." When the cold command sounded, he clenched his pocket watch and chuckled: On this express delivery, I will send myself to see the answer.
