Anchor No. 07

This is my first time writing, a short story, a bit like a composition, please forgive me. During the autopsy, forensic doctor Chen Yuan found that the spots on the body were on the pulse, which became a warning of death. Am I performing an "autopsy" on a living person? Time is turning back, and a company is implanting nanomachines in the human body, turning "time" into a controllable plague. Chen Yuan was marked as Anchor No. 07 Because of the unexpected death of his wife. What he examines is the corpse, and what he pursues is time. What is saved is the person whose death is predicted.
