One day, Gray took Elsa to visit a scientist named Allen (Harrison Gilbertson), who designed the artificial intelligence chip STEM, which amazed Elsa. On the way back, the unmanned car that Gray and Elsa were riding in broke down and took the two to a slum where thugs gathered, where the two were attacked, Elsa was unfortunately killed, and Gray was seriously injured and paralyzed in the lower body. Gray, who was full of pain and despair in his heart, wanted to avenge his lover, so he found Allen and implanted the STEM chip into his brain. Under the control of STEM, Gray stood up again.
