After modern woman Yu Sisi dies in a car accident, she accidentally time-travels to ancient times, becoming an abandoned postpartum outcast kicked out of the house by her husband's family. In desperate straits, she discovers she possesses a portable spatial dimension--the pink electric scooter and supermarket supplies she rode before her death, which regenerate daily. She acts neither as a saint nor bothers to take revenge, scraping together the last grain from the abandoned village, filling the electric scooter with supplies, carrying her daughter on her back, and riding the electric scooter straight into a chaotic world where famine is spreading.
