"If maternal love can fold time and space, I am willing to lose you thousands of times in countless parallel universes."
On the night his mother died of illness, 33-year-old Chen Mo accidentally traveled back to the primary school classroom in 1998 through a rusty school sign. When he opened his eyes amidst the chalk dust and the chirping of cicadas, he found that he was trapped in a quantum superposition state - his 9-year-old body carried adult memories, and the countdown bracelet that appeared on the inside of his arm was counting down to 719 hours, tearing his cells between two time and spaces.
The formulas on the classroom blackboard were automatically rewritten, the mathematics class representative's homework book exuded four-dimensional creases, and the school janitor Zhang's mechanical watch rotated counterclockwise... Chen Mo gradually discovered that this time travel was a desperate move by his mother that spanned thirty years. The ordinary female worker mother in her memory was actually the "space-time anchor" that maintained the stability of the multiverse, and the textile factory badge she wore was actually the highest-authority key to the quantum laboratory.
When Chen Mo tried to correct the fate of his mother's death, the man in blue from the Space-Time Administration followed him everywhere. A blood-written warning from his future self appeared in the classroom locker. Every explosion at the west city substation reshaped the world line. He had to escape between multiple dimensions: writing future equations in the playground sandpit in 1998, deciphering the star map in his mother's body in the morgue in 2023, and witnessing the death of three hundred parallel mothers at the same time in the rain of memory crystals in the sea of imaginary numbers.
As the countdown reaches zero, Chen Mo glimpses the ultimate truth at the edge of the black hole's horizon: the destruction of every universe is the choice made by his mother to continue his life. To break this bloody Möbius strip, he must sacrifice himself as a new
