Su Li, a programmer, dies in a car crash, only to be trapped inside a digital purgatory known as the City of Death.
This marks his seventh cycle of reincarnation. All six previous versions of himself perished within this city, their remains locked in mortuary lockers bearing the identical serial number: 0714.
He leads his teammates to investigate the truth, only to uncover a horrifying revelation—the mastermind behind everything is his original self. At the core of the city lies his younger sister, who passed away from illness years ago. To break the endless cycle, he must erase her entirely, wiping every trace of her from the memory of the whole world—including his own.
