When Su Tang got divorced at the Civil Affairs Bureau, the blood on her fingertips dripped on the agreement, but time went back three seconds. She discovered that her husband Shen Yanzhou had the same silver chain hidden in her best friend Lin Wanhe's sleeves, and her attendance record was marked as off-duty by the system at 23:17 every night. Shen Yanzhou's ability to look back over the past three years was used as a power bank, and every time she looked back, she took away her luck. HR Chen Yu handed over a USB flash drive and revealed that she was a replica of experimental subject S-07, and that her mother died in the Return to Origin Project. Lin Wanhe left a warning letter in the nursing home, Zhou Che secretly monitored it, and Shen's mother's mirror concealed a chain. Su Tang swallowed the timing seed chip, transparent lines appeared on his right arm, he became deaf in his left ear, and time became a prison. She must crack the return-to-origin plan within 72 hours, otherwise she will be completely adapted.
