In a world of Xuanhuan, Jiang Yu transmigrates and finds himself sharing a womb with another fetus. This fetus, however, is quite unruly, constantly competing for cultivation resources. Luckily, Jiang Yu awakens a check-in system. Meanwhile, the Empress, Liu Ruoxi, is reborn after an assassination attempt, only to find herself in a womb with a male infant. Their constant competition for resources leads to hilarious situations, culminating in the Empress's premature birth due to frustration. Years later, the now-grown Empress seeks revenge, but her path intertwines with Jiang Yu's in unexpected ways.
