When 18-year-old laboratory assistant Lu Linyuan discovers that his genes are marked as "Threshold-07", the memories of seven parallel worlds begin to erode reality. In the near future of New Shanghai, the AI system of the genetic monopoly is devouring "Lu Linyuan" from each world to improve the human evolution model. After teaming up with the homeless hacker Lao Gun, they discovered that the so-called synesthesia was actually a distress signal across time and space. When the boundary between virtuality and reality completely dissolves, Lu Linyuan must observe seven of himself at the same time to prevent human beings from being reduced to the optimal genetic arrangement.
