After years of hard cultivation, Su Rongrong, a thousand-year-old rabbit demon, had reached the final hurdle on her path to immortality, but could make no further progress. Just as she was fretting over her predicament, she unexpectedly became bound to the "Childbearing System for Those Destined to Have No Heirs." The System told her that only by traveling through three thousand small worlds and helping male leads fated to have no heirs overcome their fertility problems and have children to carry on their bloodlines could she accumulate enough merit to break through her bottleneck and ascend to immortality.
Clinging to her devotion to the Great Way, Su Rongrong resolutely embarked on her missions. With a rabbit demon's innate gift for prolific breeding and the pure spiritual energy she had cultivated, she precisely solved the male leads' fertility problems in each world. From a reserved prince in a royal manor, to a modern business tycoon, to the commander of an interstellar federation, she not only fulfilled her mission to bear children each time, but also found a different kind of warmth in her relationships with the various male leads.
As she completed one small-world mission after another, her merit gradually reached perfection and Su Rongrong drew ever closer to her goal of ascending to immortality. Thus began a cultivation journey across three thousand worlds, turning her dream into reality.
After reading the first story, I can only say that it is too immature. The target of the strategy is just a background. Gong Dou is also playing house and makes me laugh to death. The emperor does not know why he has no children until he dies. There is no love scene at all and he gets pregnant. The male protagonist of Small World has no personality charm.
