In the early 1940s of the twenty-first century, inside a laboratory in Beiping, Xiang Shan was sitting at the control panel. Behind him were several experts, including Chen Feng. These researchers mostly came from the field of cognitive science.
Opposite them was a man sitting on a chair. The man was roughly in his fifties, wearing a device on his head that somewhat resembled the goggles of a video game character's cosplay. However, the device was fundamentally decorative, intended to mitigate the uncanny valley effect caused by his oversized prosthetic eyes—his wife and children had complained multiple times before that his prosthetic eyes were "scary".
Early prosthetic eyes were slightly larger than the eyeballs of Natural Persons.
