Sleepwalking Zero

2041, Yungang. A police detective who specializes in catching "out-of-control androids" is tracking down a series of murders in the city - each of the androids who commit crimes repeats a sentence in his dream before dying. He thought he was tracking the murderer until one day, he saw the joint on the back of his neck in the reflection of the one-way glass. Seven lives, panic in a city, and a "Pure Humanity Act" that is about to be passed - it begins with one thousand one hundred and thirty-seven days of silence.
