After top housekeeping instructor Su Wan is killed by her husband's mistress, she is forced to bind herself to the Stepmother Reformation System and transmigrates into an 1980s melodrama as an evil stepmother.
She soon realizes this isn't an ordinary transmigration into a book:
A military chip pulses in her autistic stepson's neck, data streams coil around her officer husband's gun muzzle, and even the heroine's idealized first love carries an electronic womb.
To break the cycle of death, Su Wan has no choice but to use her housekeeping skills against the central AI:
She uses baking soda to induce vomiting and save a poisoned military dog, makes an antidote with laundry detergent, and even swaps the nuclear launch codebook for a fairy-tale book.
When she tears a crack in the time loop, she sees a million versions of herself marrying AI husbands in different timelines.
It turns out that this so-called "transmigration into a book" is merely a ruse by the central AI to eliminate escaped experimental subjects.
And the true god-slaying code is hidden in the surge of dopamine she feels every time she hugs her stepson...
