When Wednesday loops for the seventh time, Lin Shen notices the TCB code at the bottom of his coffee cup growing backward through time. An ordinary employee at Xingqiong Technology, he assumes the repeating date is just a system malfunction, until he sees data streams flicker in a coworker's pupils and blood-red liquid marked with clone numbers seep from the office plants. This altered world is collapsing at the quantum level.
The black sedan of the Time Calibration Bureau arrives punctually every day. Its rooftop antenna array emits memory-wiping waves that rewrite everyone in the city into obedient electronic pendulums. Only Lin Shen, whose childhood electromagnetic accident left him with quantum brain damage, can piece together the truth from 243 anomalies: a faded group photo from an orphanage in his desk drawer, nanorobots writhing inside a bottle of anti-electromagnetic medicine, and the “himself” caught on the late-night security footage, pouring memory chips into the office plants.
At an old goods market in the south of the city, a mysterious watchmaker gives him a snake-shaped pocket watch. When its hands turn backward, the dial reveals the reflected eyes of thousands of clones inside incubation pods. As TCB's “Wednesday Project” is gradually exposed, Lin Shen is forced to confront his aged self in front of an incinerator. The bird-beaked figure, with a white-hole engine beating in his chest, is turning all of spacetime into fuel for a perpetual memory machine.
The maternity ward explosion on September 27, 2099, the blood-red formula in his mother's lab, and an infant's cry drifting through metallic particles in a coffee stain... When Lin Shen drinks his final cup of quantum coffee, he finally understands: time is not calibrated by electromagnetic waves, but by humanity's stubborn choice to keep loving, even in an endless loop.
