Infinity tells the story of an artificial man. Mi Xiaolei is the main character of this story. The story revolves around the mystery of Xiao Lei's life experience. She was originally a child with a family, but because she was captured in a laboratory when she was a child, she became one of the experimental subjects and had her DNA modified. From then on, she became an artificial person that is neither human nor human. Although she is a completely copied artificial human being, transformed from a real human body, there is not much difference.
As for the rest of the artificial humans, they are truly man-made humans. For example, Pink is a human created by scientists using human DNA and animal DNA.
In the process of searching for his own life experience, Xiaolei discovered that his unchanging heart was actually moved by one person. And that person turned out to be him... The boy who was related to the secret of her life experience...
